2004 Dodge Dakota Owners Manual

ments, refer to the 9Shifting Procedure9 for your transfer case, located in this section of the owner’s manual. The SERVICE 4WD warning light monitors the electric shift 4WD system. If this light remains on after engine start up or illuminates during driving, it means that the 4WD system is not functioning properly and that service is required.

WARNING!

Always engage the parking brake when powering down the vehicle if the (Service 4WD( light is illuminated. Not engaging the parking brake may allow the vehicle to roll which may cause personal injury.

NOTE: Do not attempt to make a shift while only the front or rear wheels are spinning. The NV244 transfer case is not equipped with a synchronizer and therefore the front and rear driveshaft speeds must be equal for the

shift to take place. Shifting while only the front or rear wheels are spinning can cause damage to the transfer case. When operating your vehicle in 4LO, the engine speed is approximately three times that of the AWD or 4HI positions at a given road speed. Take care not to over- speed the engine and do not exceed 25 mph (40 km/h). Proper operation of 4 wheel drive vehicles depends on tires of equal size, type and circumference on each wheel. Any difference in tire size can cause damage to the transfer case. Because 4 wheel drive provides improved traction, there is a tendency to exceed safe turning and stopping speeds. Do not go faster than road conditions permit.

STARTING AND OPERATING 159

WARNING!

You or others could be injured if you leave the vehicle unattended with the transfer case in the Neutral (N) position without first fully engaging the parking brake. The transfer case Neutral (N) position disengages both the front and rear driveshafts from the powertrain and will allow the vehicle to move regardless of the transmission position. The parking brake should always be applied when the driver is not in the vehicle.

For additional information on the appropriate use of each transfer case mode position see the information below: AWD Normal All Wheel Drive High Range - Employs inter- axle differential. Allows front and rear wheels to rotate at different speeds. All road surfaces.

160 STARTING AND OPERATING

4HI 4 Wheel Drive High Range - Locks the transfer case inter-axle differential. Forces front and rear wheels to rotate at the same speed. Additional traction for loose, slippery road surfaces only. 4LO 4 Wheel Drive Low Range - Low speed 4 wheel drive. Locks the transfer case inter-axle differential. Forces the front and rear wheels to rotate at the same speed. Additional traction and maximum pulling power for loose, slippery road surfaces only. Do not exceed 25 mph (40 km/h). Neutral - Disengages both the front and rear driveshafts from the powertrain. To be used for flat towing behind another vehicle. See Recreational Towing for more infor- mation.

Shifting Procedure - NV244 Transfer Case

If any of the requirements to select a new NOTE: transfer case position have not been met, the transfer case will not shift.The indicator light for the previous position will remain ON and the newly selected position indicator light will continue to flash until all the requirements for the selected position have been met. To retry a shift: return the control knob back to the original position, make certain all shift requirements have been met, wait five (5) seconds and try the shift again.

AWD to 4HI or 4HI to AWD Rotate the 4WD Control Switch to the desired position. Shifts between AWD and 4HI can be done with the vehicle stopped or in motion. With the vehicle in motion, the transfer case will engage / disengage faster if you momentarily release the accelerator pedal after turning the control switch. If the vehicle is stopped the ignition key must be in the ON position with the engine either RUNNING or OFF. This shift cannot be completed if the key is in the accessory position. NOTE: On vehicles equipped with a Anti-Lock Brake Systems, the 4x4 system will not allow shifts between AWD/ 4HI if the rear wheels are spinning (no traction). In this situation the selected position indicator light will flash and the original position indicator light will remain ON. At this time, reduce speed and stop spinning the wheels to complete the shift. There may be a delay up to 10 seconds for the shift to complete after the wheels have stopped spinning. NOTE: Delayed shifting out of the 4HI position may be experienced due to uneven tire wear, low tire pressure, or excessive loading.

STARTING AND OPERATING 161

4HI to 4LO or 4LO to 4HI NOTE: When shifting into or out of 4LO some gear noise may be heard. This noise is normal and is not detrimental to the vehicle or occupants. Shifting can be performed with the vehicle rolling 2-3
mph (3-5 km/h) or completely stopped. USE EITHER OF THE FOLLOWING PROCEDURES: Preferred Procedure 1. With engine RUNNING, slow vehicle to 2-3 mph (3-5
km/h). 2. Shift the transmission into NEUTRAL (depress clutch on manual transmissions). 3. Ensure ignition key is in the ON position with the engine either RUNNING or OFF. While still rolling, rotate the transfer case control switch to the desired position. 4. After the desired position indicator light is ON (not flashing), shift transmission back into gear (release clutch on manual transmissions).

162 STARTING AND OPERATING

Alternate Procedure 1. Bring the vehicle to complete stop. 2. With the key ON and the engine either OFF or RUNNING, shift the transmission into NEUTRAL (de- press clutch on manual transmissions). 3. Rotate the transfer case control switch to the desired position. 4. After the desired position indicator light is ON (not flashing), shift transmission back into gear (release clutch on manual transmissions). If steps 1 or 2 of either the Preferred or Alternate NOTE: Procedure are not satisfied prior to attempting the shift or if they no longer are being met while the shift attempt is in process, then the desired position indicator light will flash continuously while the original position indicator light is ON, until all requirements have been met. NOTE: The ignition key must be ON for a shift to take place and for the position indicator lights to be operable. If the key is not ON then the shift will not take place and no position indicator lights will be on or flashing.

LIMITED-SLIP DIFFERENTIAL — IF EQUIPPED The limited-slip differential provides additional traction on snow, ice, mud, sand and gravel. It improves traction when there is a difference between the characteristics of the surface under the right and left rear wheels. During normal driving and cornering, the limited-slip unit is similar to a conventional differential. But on a slippery surface, the differential delivers more of the driving effort to the wheel having the better traction.

WARNING!

On vehicles equipped with a limited-slip differen- tial, never run the engine with one rear wheel off the ground. The vehicle may drive through the rear wheel remaining on the ground and cause you to lose control of the vehicle.

Care should be taken to avoid sudden accelerations when both rear wheels are on a slippery surface. This could cause both rear wheels to spin, and allow the vehicle to slide sideways on the crowned surface of a road or in a turn.

PARKING BRAKE The parking brake should be applied whenever the driver is not in the vehicle. The foot operated parking brake is positioned below the lower left corner of the instrument panel.

To apply the parking brake: Place your foot on the parking brake pedal and push firmly downward as far as the pedal will go. When the parking brake is applied and the ignition is ON, the BRAKE light in the instrument cluster will light.

STARTING AND OPERATING 163

NOTE: The BRAKE light in the instrument cluster indicates only that the parking brake is applied—it does not indicate the degree of application. To release the parking brake: Pull the parking brake release handle towards you. The BRAKE light in the instrument cluster will go out when the parking brake is disengaged. To park on a hill: You must make sure that the parking brake is fully applied and the gear shift lever is in PARK (for an automatic transmission) or in REVERSE or FIRST (for a manual transmission). You should apply the park- ing brake before shifting to PARK; otherwise, the load on the transmission locking mechanism may make it diffi- cult to move the shift lever out of the Park position. When parking on a hill, turn the front wheels: † Toward the curb on a downhill grade. † Away from the curb on an uphill grade.

164 STARTING AND OPERATING

WARNING!

† Always fully apply the parking brake when leav- ing your vehicle, or vehicle may roll and cause damage or injury. Also be certain to leave an automatic transmission in Park, a manual trans- mission in Reverse or first gear. Failure to do so may cause the vehicle to roll and cause damage or injury. † Be sure the parking brake is fully disengaged before driving. Failure to do so can lead to brake failure and an accident. † Leaving children in a vehicle unattended is dan- gerous for a number of reasons. A child or others could be injured. Children should be warned not to touch the parking brake or the gear selector lever. Don’t leave the key in the ignition. A child could operate power windows, other controls, or move the vehicle.

BRAKE SYSTEM In the event power assist is lost for any reason (for example, repeated brake applications with the engine off), the brakes will still function. The effort required to brake the vehicle will be significantly increased over that required with the power system operating. If either the front or rear hydraulic system loses normal capability, the remaining system will still function with some loss of braking effectiveness. This will be evident by increased pedal travel during application, greater pedal force required to slow or stop, and activation of the Brake Warning light and the ABS light during brake use. Rear Wheel Anti-Lock Brake System This Anti-Lock Brake System provides increased vehicle stability and brake performance under most braking conditions. The system automatically controls the opera- tion of the rear brakes to prevent rear wheel lockup. The system remains operational in the four-wheel drive mode. The level of performance is reduced when the front brakes are locked up. This will cause the rear brakes to lock-up through the drivetrain, which may reduce the effectiveness of the anti-lock system.

During severe braking conditions, particularly with changing road surfaces, such as ice to concrete, a slight drop or minor pulsation may be felt in the brake pedal.

WARNING!

Both Anti-Lock Brake Systems contain sophisticated electronic equipment. It may be susceptible to inter- ference caused by improperly installed or high out- put radio transmitting equipment. This interference can cause possible loss of anti-lock braking capabil- ity. Installation of such equipment should be done by qualified professionals.

Four-Wheel Anti-Lock Brake System — If Equipped This Anti-Lock Brake System is designed to aid the driver in maintaining vehicle control under adverse braking conditions. The system operates with a separate com- puter to modulate hydraulic pressure to prevent wheel lock-up and help avoid skidding on slippery surfaces.

STARTING AND OPERATING 165

The system’s pump motor runs during an ABS stop to provide regulated hydraulic pressure. The pump motor makes a low humming noise during operation, which is normal. The Anti-Lock Brake System includes an amber ABS warning light. When the light is illuminated, the Anti- Lock Brake System is not functioning. The system reverts to standard non-anti-lock brakes. Turning the ignition OFF and ON again may reset the Anti-Lock Brake System if the fault detected was only momentary.

WARNING!

Pumping of the Anti-Lock Brakes will diminish their effectiveness and may lead to an accident. Pumping makes the stopping distance longer. Just press firmly on your brake pedal when you need to slow down or stop.

166 STARTING AND OPERATING

WARNING!

† Anti-lock system (ABS) cannot prevent the natu- ral laws of physics from acting on the vehicle, nor can it increase braking or steering efficiency be- yond that afforded by the condition of the vehicle brakes and tires or the traction afforded.

† The ABS cannot prevent accidents,

including those resulting from excessive speed in turns, following another vehicle too closely, or hydro- planing. Only a safe, attentive, and skillful driver can prevent accidents. † The capabilities of an ABS equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others.

When you are in a severe braking condition involving use of the Anti-lock Brake System, you will experience some pedal drop as the vehicle comes to a stop. This is the result of the system reverting to the base brake system. Engagement of the Anti-lock Brake System may be accompanied by a pulsing sensation. You may also hear a clicking noise. These occurrences are normal, and indi- cate that the system is functioning properly.

POWER STEERING Your power steering system will provide mechanical steering capability if power assist is lost. If for any reason the hydraulic pressure is interrupted, it will still be possible to steer your vehicle. Under these conditions you will experience an increase in steering effort and a noticeable amount of “free play” in the steering wheel.

ROCKING THE VEHICLE If vehicle becomes stuck in snow, sand, or mud, it can often be moved by a rocking motion. Move the gear selector rhythmically between FIRST and REVERSE, while applying slight pressure to the accelerator. The least amount of accelerator pedal pressure to main- tain the rocking motion without spinning the wheels or racing the engine is most effective. Allow the engine to idle with the transmission selector in NEUTRAL for at least one minute after every five rocking-motion cycles. This will minimize overheating and reduce the risk of transmission failure during prolonged efforts to free a stuck vehicle.

172 STARTING AND OPERATING

Tire Loading and Tire Pressure

Tire Placard Location NOTE: Some vehicles have a “Tire and Loading Infor- mation” placard located on the driver’s side “B” pillar.

Tire and Loading Information Placard

This placard tells you important information about the, 1) number of people that can be carried in the vehicle 2) the total weight your vehicle can carry 3) the tire size designed for your vehicle 4) the cold tire inflation pressures for the front, rear and spare tires. Loading The vehicle maximum load on the tire must not exceed the load carrying capacity of the tire on your vehicle. You will not exceed the tire’s load carrying capacity if you

adhere to the loading conditions, tire size and cold tire inflation pressures specified on the Tire and Loading Information placard and the Vehicle Loading section of this manual. NOTE: Under a maximum loaded vehicle condition, gross axle weight ratings (GAWR’s) for the front and rear axles must not be exceeded. For further information on GAWR’s, vehicle loading and trailer towing, see the Vehicle Loading section of this manual. To determine the maximum loading conditions of your vehicle, locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on the Tire and Loading Information placard. The combined weight of occupants, cargo/luggage and trailer tongue weight (if applicable) should never exceed the weight referenced here. Steps for Determining Correct Load Limit 1. Locate the statement “The combined weight of occu- pants and cargo should never exceed XXX pounds” on your vehicle’s placard. 2. Determine the combined weight of the driver and passengers that will be riding in your vehicle.

STARTING AND OPERATING 173

3. Subtract the combined weight of the driver and pas- sengers from XXX kilograms or XXX pounds. 4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if “XXX” amount equals 1400 lbs. and there will be five 150 lb. passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lb. (1400–750 (5 x 150) = 650 lb.) 5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in step 4. 6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle. NOTE: The following table shows examples on how to calculate total load, cargo/luggage and towing capacities of your vehicle with varying seating configurations and number and size of occupants. This table is for illustra- tion purposes only and may not be accurate for the seating and load carry capacity of your vehicle.

174 STARTING AND OPERATING

NOTE: For the following example the combined weight of occupants and cargo should never exceed 865 lbs. (392 Kg).

WARNING!

1. Safety—

STARTING AND OPERATING 175

Overloading of your tire is dangerous. Overloading can cause tire failure, affect vehicle handling, and increase your stopping distance. Use tires of the recommended load capacity for your vehicle. Never overload them.

TIRES—GENERAL INFORMATION

Tire Pressure Proper tire inflation pressure is essential to the safe and satisfactory operation of your vehicle. Three primary areas are affected by improper tire pressure:

WARNING!

Improperly inflated tires are dangerous and can cause accidents. † Under inflation increases tire flexing and can result in tire failure. † Over inflation reduces a tire’s ability to cushion shock. Objects on the road and chuck holes can cause damage that results in tire failure. † Unequal tire pressures can cause steering prob- lems. You could lose control of your vehicle. † Over inflated or under inflated tires can affect vehicle handling and can fail suddenly, resulting in loss of vehicle control. † Unequal tire pressures from one side of the vehicle to the other can cause the vehicle to drift to the right or left. Always drive with each tire inflated to the recom- mended cold tire inflation pressure.

176 STARTING AND OPERATING

2. Economy— Improper inflation pressures can cause uneven wear patterns to develop across the tire tread. These abnormal wear patterns will reduce tread life resulting in a need for earlier tire replacement. Underinflation also increases tire rolling resistance and results in higher fuel consumption. 3. Ride Comfort and Vehicle Stability— Proper tire inflation contributes to a comfortable ride. Overinflation produces a jarring and uncomfortable ride. Tire Inflation Pressures The proper cold tire inflation pressure for passenger cars is listed on either the face of the driver’s door or the driver’s side “B” pillar. For vehicles other than passenger cars, the cold tire inflation pressures are listed on either the “B” pillar, the Certification Label or in the Tire Inflation Pressures brochure in the glove compartment. Some vehicles may have Supplemental Tire Pressure Information for vehicle loads that are less that the maxi- mum loaded vehicle condition. These pressure condi- tions will be found in the “Supplemental Tire Pressure Information” section of this manual.

“B” PILLAR

The pressure should be checked and adjusted as well as inspecting for signs of tire wear or visible damage at least once a month. Use a good quality pocket-type gauge to check tire pressure. Do not make a visual judgement when determining proper inflation. Radial tires may look properly inflated even when they are underinflated.

CAUTION!

After inspecting or adjusting the tire pressure al- ways reinstall the valve stem cap–if equipped. This will prevent moisture and dirt from entering the valve stem, which could damage the valve stem.

Inflation pressures specified on the placard are always “cold tire inflation pressure”. Cold tire inflation pressure is defined as the tire pressure after the vehicle has not been driven for at least 3 hours, or driven less than 1mile (1 km) after a 3 hour period. The cold tire inflation pressure must not exceed the maximum inflation pres- sure molded into the tire side wall. Check tire pressures more often if subject to a wide range of outdoor temperatures, as tire pressures vary with temperature changes. Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C) of air temperature change. Keep this in mind when checking tire pressure inside a garage especially in the winter.

STARTING AND OPERATING 177

Example: If garage temperature = 68° F (20° C) and the outside temperature = 32° F (0° C) then the cold tire inflation pressure should be increased by 3 psi (21 kPa), which equals 1 psi (7 kPa) for every 12° F (7° C) for this outside temperature condition. Tire pressure may increase from 2 to 6 psi (13 to 40 kPa) during operation. DO NOT reduce this normal pressure build up or your tire pressure will be too low. Tire Pressures for High Speed Operation The manufacturer advocates driving at safe speeds within posted speed limits. Where speed limits or condi- tions are such that the vehicle can be driven at high speeds, maintaining correct tire inflation pressure is very important. Increased tire pressure and reduced vehicle loading may be required for high speed vehicle opera- tion. Refer to original equipment or an authorized tire dealer for recommended safe operating speeds, loading and cold tire inflation pressures.

178 STARTING AND OPERATING

WARNING!

High speed driving with your vehicle under maxi- mum load is dangerous. The added strain on your tires could cause them to fail. You could have a serious accident. Don’t drive a vehicle loaded to the maximum capacity at continuous speeds above 75
mph (120 km/h).

Radial-Ply Tires

WARNING!

Combining radial ply tires with other types of tires on your vehicle will cause your vehicle to handle poorly. The instability could cause an accident. Al- ways use radial ply tires in sets of four (or 6, in case of trucks with dual rear wheels). Never combine them with other types of tires.

Cuts and punctures in radial tires are repairable only in the tread area because of sidewall flexing. Consult your authorized tire dealer for radial tire repairs. Compact Spare Tire — If Equipped The compact spare is for temporary emergency use with radial tires. It is engineered to be used on your style vehicle only. Since this tire has limited tread life, the original tire should be repaired (or replaced) and rein- stalled at the first opportunity.

WARNING!

Temporary use spare tires are for emergency use only. With these tires, do not drive more than 50 mph (80 km/h). Temporary-use spare tires have a total tread life of 3,000 miles (4 800 km). Be sure to follow the warnings which apply to your spare. Failure to do so could result in spare tire failure and loss of vehicle control.

Do not install a wheel cover or attempt to mount a conventional tire on the compact spare wheel, since the wheel is designed specifically for the compact spare. Do not install more than one compact spare tire/wheel on the vehicle at any given time.

Tire Spinning When stuck in mud, sand, snow, or ice conditions, do not spin your vehicle’s wheels above 35 mph (55 km/h). See the paragraph on Freeing A Stuck Vehicle in Section 6 of this manual.

STARTING AND OPERATING 179

CAUTION!

WARNING!

Because of the reduced ground clearance, do not take your vehicle through an automatic car wash with the compact spare installed. Damage to the vehicle may result.

Fast spinning tires can be dangerous. Forces gener- ated by excessive wheel speeds may cause tire dam- age or failure. A tire could explode and injure someone. Do not spin your vehicle’s wheels faster than 35 mph (55 km/h) when you are stuck. And don’t let anyone near a spinning wheel, no matter what the speed.

180 STARTING AND OPERATING

Tread Wear Indicators Tread wear indicators are in the original equipment tires to help you in determining when your tires should be replaced.

These indicators are molded into the bottom of the tread grooves and will appear as bands when the tread depth becomes 1/16 inch (2 mm). When the indicators appear in 2 or more adjacent grooves, the tire should be replaced. Many states have laws requiring tire replacement at this point.

Replacement Tires The tires on your new vehicle provide a balance of many characteristics. They should be inspected regularly for wear and correct cold tire inflation pressure. The manu- facturer strongly recommends that you use tires equiva- lent to the originals in size, quality and performance when replacement is needed (see the paragraph on tread wear indicators). Refer to the Tire and Loading Informa- tion placard for the size designation of your tire. The service description and load identification will be found on the original equipment tire. Failure to use equivalent replacement tires may adversely affect the safety, han- dling, and ride of your vehicle. We recommend that you contact your original equipment or an authorized tire dealer with any questions you may have on tire specifi- cations or capability.

WARNING!

† Do not use a tire, wheel size or rating other than that specified for your vehicle. Some combina- tions of unapproved tires and wheels may change suspension dimensions and performance charac- teristics, resulting in changes to steering, han- dling, and braking of your vehicle. This can cause unpredictable handling and stress to steering and suspension components. You could lose control and have an accident resulting in serious injury or death. Use only the tire and wheel sizes with load ratings approved for your vehicle. † Never use a tire with a smaller load index or capacity, other than what was originally equipped on your vehicle. Using a tire with a smaller load index could result in tire overloading and failure. You could lose control and have an accident. † Failure to equip your vehicle with tires having adequate speed capability can result in sudden tire failure and loss of vehicle control.

STARTING AND OPERATING 181

CAUTION!

Replacing original tires with tires of a different size may result in false speedometer and odometer read- ings.

wear.

Alignment And Balance Poor suspension alignment may result in: † Fast tire wear. † Uneven tire wear, such as feathering and one-sided † Vehicle pull to right or left. Tires may also cause the vehicle to pull to the left or right. Alignment will not correct this condition. See your dealer for proper diagnosis. Improper alignment will not cause vehicle vibration. Vibration may be a result of tire and wheel out-of- balance. Proper balancing will reduce vibration and avoid tire cupping and spotty wear.

182 STARTING AND OPERATING

SUPPLEMENTAL TIRE PRESSURE INFORMATION A light load vehicle condition is defined as two passen- gers {150 lbs (68 kg) each} plus 200 lbs (91kg) of cargo. Cold tire inflation pressures for a lightly loaded vehicle will be found on a “Supplemental Tire Pressure Inflation” label located on the face of the driver’s door or in the Tire Information Pressures pamphlet in the glove box.

TIRE CHAINS Use only Class S chains, or other traction aids that meet SAE specifications. Chains must be the proper size for the vehicle as recommended by the chain manufacturer. These cautions apply to all chain traction devices, includ- ing link and cable (radial) chains.

CAUTION!

To avoid damage to your vehicle, tires or chains observe the following precautions:

† Because of restricted chain clearance between tires and other suspen-

about 1/2 mile (0.8 km).

sion components, it is important that only chains in good condition are used. Broken chains can cause serious damage. Stop the vehicle immediately if noise occurs that could indicate chain breakage. Remove the damaged parts of the chain before further use.

† Install chains as tightly as possible and then retighten after driving † Do not exceed 30 mph (48 km/h). † Drive cautiously and avoid severe turns and large bumps, especially † Install only Class S chains on 4x2 and 4x4 vehicles. † Do not install tire chains on the front wheels of 4x2 vehicles. † Do not install tire chains or traction devices on rear wheels of 4x2
† Do not install tire chains or traction devices on front wheels of 4x4

installation, operating speed, and conditions for usage. Always use the lower suggested operating speed if both the chain manufacturer and the vehicle manufacturer suggest a maximum speed.

SNOW TIRES Snow tires should be of the same size and type construc- tion as the front tires. Consult the manufacturer of the snow tire to determine any maximum vehicle speed requirement associated with the tire. These tires should always be operated at the vehicle maximum capacity inflation pressures under any load condition. While studded tires improve performance on ice, skid and traction capability on wet or dry surfaces may be poorer than that of non-studded tires. Some states pro- hibit studded tires; local laws should be checked before using these tire types.

therefore,

STARTING AND OPERATING 183

TIRE ROTATION RECOMMENDATIONS Tires on the front and rear axles of vehicles operate at different loads and perform different steering, driving, and braking functions. For these reasons, they wear at unequal rates and tend to develop irregular wear pat- terns. These effects can be reduced by timely rotation of tires. The benefits of rotation are especially worthwhile with aggressive tread designs such as those on all season type tires. Rotation will increase tread life, help to main- tain mud, snow and wet traction levels, and contribute to a smooth, quiet ride.

184 STARTING AND OPERATING

Follow the recommended tire rotation frequency for your type of driving found in the “Maintenance Schedules” Section of this manual. More frequent rotation is permis- sible if desired. The reasons for any rapid or unusual wear should be corrected prior to rotation being per- formed.

FUEL REQUIREMENTS Your engine is designed to meet all emissions regulations and provide excellent fuel economy and performance when using high quality unleaded “regular” gasoline having an octane rating of 87. The routine use of pre- mium gasoline is not recommended. Under normal con- ditions the use of premium fuel will not provide a benefit over high quality regular gasolines and in some circum- stances may result in poorer performance.

Light spark knock at low engine speeds is not harmful to your engine. However, con- tinued heavy spark knock at high speeds can cause damage and immediate service is required. Engine damage resulting from operation with a heavy spark knock may

not be covered by the new vehicle warranty.

Poor quality gasoline can cause problems such as hard starting, stalling and hesitations. If you experience these symptoms, try another brand of “regular” gasoline be- fore considering service for the vehicle. Over 40 auto manufacturers world-wide have issued and endorsed consistent gasoline specifications (the World- wide Fuel Charter, WWFC) to define fuel properties necessary to deliver enhanced emissions, performance and durability for your vehicle. The manufacturer recom- mends the use of gasolines that meet the WWFC speci- fications if they are available. Reformulated Gasoline Many areas of the country require the use of cleaner burning gasoline referred to as “Reformulated Gasoline.” Reformulated gasolines contain oxygenates, and are spe- cifically blended to reduce vehicle emissions and im- prove air quality. The manufacturer strongly supports the use of reformu- lated gasolines. Properly blended reformulated gasolines will provide excellent performance and durability for the engine and fuel system components.

Gasoline/Oxygenate Blends Some fuel suppliers blend unleaded gasoline with oxy- genates such as 10% ethanol, MTBE and ETBE. Oxygen- ates are required in some areas of the country during the winter months to reduce carbon monoxide emissions. Fuels blended with these oxygenates may be used in your vehicle.

CAUTION!

DO NOT use gasolines containing METHANOL. Gasoline containing methanol may damage critical fuel system components.

MMT In Gasoline MMT is a manganese-containing metallic additive that is blended into some gasoline to increase octane. Gasolines blended with MMT provide no performance advantage beyond gasolines of the same octane number without MMT. Gasolines blended with MMT reduce spark plug life and reduce emission system performance in some vehicles. We recommend that gasolines free of MMT be

STARTING AND OPERATING 185

used in your vehicle. The MMT content of gasoline may not be indicated on the gasoline pump; therefore, you should ask your gasoline retailer whether or not his/her gasoline contains MMT. It is even more important to look for gasolines without MMT in Canada because MMT can be used at levels higher than allowed in the United States. MMT is pro- hibited in Federal and California reformulated gasolines. Sulfur In Gasoline If you live in the northeast United States, your vehicle may have been designed to meet California low emission standards with Cleaner-Burning California reformulated gasoline with low sulfur. If such fuels are not available in states adopting California emission standards, your ve- hicles will operate satisfactorily on fuels meeting federal specifications, but emission control system performance may be adversely affected. Gasoline sold outside of California is permitted to have higher sulfur levels which may affect the performance of the vehicle’s catalytic converter. This may cause the Check Engine or Service Engine Soon light to illuminate. We recommend that you try a different brand of unleaded gasoline having lower

186 STARTING AND OPERATING

sulfur to determine if the problem is fuel related prior to returning your vehicle to an authorized dealer for ser- vice.

CAUTION!

If the Check Engine or Service Engine Soon light is flashing, immediate service is required; see onboard diagnostics system section.

Materials Added To Fuel All gasolines sold in the United States are required to contain effective detergent additives. Use of additional detergents or other additives is not needed under normal conditions and would result in unnecessary cost. There- fore, you should not have to add anything to the fuel.

ADDING FUEL

Fuel Filler Cap (Gas Cap)

The gas cap is behind the fuel filler door. If the gas cap is lost or damaged, be sure the replacement cap is for use with this vehicle.

CAUTION!

Damage to the fuel system or emission control system could result from using an improper fuel tank filler tube cap (gas cap). A poorly fitting cap could let impurities into the fuel system.

WARNING!

† Remove the fuel tank filler tube cap (gas cap) slowly to prevent fuel spray from the filler neck which may cause injury. † The volatility of some gasolines may cause a buildup of pressure in the fuel tank that may increase while you drive. This pressure can result in a spray of gasoline and/or vapors when the cap is removed from a hot vehicle. Removing the cap slowly allows the pressure to vent and prevents fuel spray. † Never allow any lit smoking materials near the vehicles while removing the cap or filling the tank. † Never add fuel to the vehicle when the engine is

running.

STARTING AND OPERATING 187

Fuel Tank Filler Tube

NOTE: On some models, the fuel tank filler tube has a restricting door about 2 inches (50 mm) down from the opening. If fuel is poured from a portable container, the container should have a flexible nozzle long enough to force open the restricting door.

CAUTION!

To avoid fuel spillage and overfilling, do not “top off” the fuel tank after filling.

NOTE: When the fuel nozzle “clicks” or shuts off, the fuel tank is full. NOTE: Tighten the gas cap until you hear a “clicking” sound. This is an indication that the gas cap is properly tightened. The Check Engine light will come on if the gas cap is not properly secured. Make sure that the gas cap is tightened each time the vehicle is refueled.

188 STARTING AND OPERATING

WARNING!

A fire may result if gasoline is pumped into a portable container that is inside of a vehicle. You could be burned. Always place gas containers on the ground while filling.

Fuel System Cautions

CAUTION!

Follow these guidelines to maintain your vehicle’s performance: † The use of leaded gas is prohibited by Federal law. Using leaded gasoline can impair engine performance, damage the emission control system, and could result in loss of warranty coverage. † An out-of-tune engine, or certain fuel or ignition malfunctions, can cause the catalytic converter to overheat. If you notice a pungent burning odor or

some light smoke, your engine may be out of tune or malfunctioning and may require immediate service. Contact your dealer for service assistance. † When pulling a heavy load or driving a fully loaded vehicle when the humidity is low and the temperature is high, use a premium unleaded fuel to help prevent spark knock. If spark knock persists, lighten the load, or engine piston damage may result. † The use of fuel additives which are now being sold as octane enhancers is not recommended. Most of these products contain high concentrations of methanol. Fuel system damage or vehicle performance problems resulting from the use of such fuels or additives is not the responsibility of the manufacturer and may not be covered under the New Vehicle Warranty.

NOTE: systems can result against you.

Intentional tampering with emissions control in civil penalties being assessed

STARTING AND OPERATING 189

† Keep the liftgate closed when driving your vehicle to prevent carbon monoxide and other poisonous ex- haust gases from entering the vehicle.

CATALYTIC CONVERTER The catalytic converter requires the use of unleaded fuel only. Leaded gasoline will destroy the effectiveness of the converter as an emission control device. Under normal operating conditions, the catalytic converter will not require maintenance. However, you must keep the en- gine maintained to assure proper operation and prevent possible damage. Intentional tampering with emissions control NOTE: systems result in civil penalties being assessed against you.

Carbon Monoxide Warnings

WARNING!

Carbon monoxide (CO) in exhaust gases is deadly. Follow the precautions below to prevent carbon monoxide poisoning: † Do not inhale exhaust gases. They contain carbon monoxide, a colorless and odorless gas which can kill. Never run the engine in a closed area, such as a garage, and never sit in a parked vehicle with the engine running for an extended period. If the vehicle is stopped in an open area with the engine running for more than a short period, adjust the ventilation system to force fresh, outside air into the vehicle. † Guard against carbon monoxide with proper mainte- nance. Have the exhaust system inspected every time the vehicle is raised. Have any abnormal conditions repaired promptly. Until repaired, drive with all side windows fully open.

190 STARTING AND OPERATING

CAUTION!

Damage to the catalytic converter can result if your vehicle is not kept in proper operating condition. In the event of engine malfunction, particularly involv- ing engine misfire or other apparent loss of perfor- mance, have your vehicle serviced promptly. Contin- ued operation of your vehicle with a severe malfunction could cause the converter to overheat, resulting in possible damage to the converter and vehicle.

As with any vehicle do not park or operate this vehicle in areas where combustible materials such as grass or leaves can contact a hot exhaust system. A scorching odor may appear if you continue to run a malfunctioning engine. The odor may indicate severe and abnormal catalyst overheating. If this occurs, the vehicle should be stopped, the engine shut off and the vehicle allowed to cool. Service, including a tune-up to manufacturer’s specifications should be obtained imme- diately.

vehicle.

To minimize the possibility of catalytic converter dam- age: † Do not shut off the engine or interrupt the ignition when the transmission is in gear and the vehicle is in motion. † Do not try to start the engine by pushing or towing the † Do not idle the engine with any spark plug wires disconnected or removed, such as when diagnostic testing. † Do not idle the engine for prolonged periods during very rough idle or malfunctioning operating condi- tions.

† Do not allow vehicle to run out of fuel. NOTE: systems can result against you.

VEHICLE LOADING

Certification Label As required by National Highway Traffic Safety Admin- istration Regulations, your vehicle has a certification label affixed to the driver’s side door or pillar.

This label contains the month and year of manufacture, Gross Vehicle Weight Rating (GVWR), Gross Axle Weight Rating (GAWR) front and rear, and Vehicle Identification Number (VIN). A Month-Day-Hour (MDH) number is included on this label and shows the Month, Day, and

STARTING AND OPERATING 191

Hour of manufacture. The bar code that appears on the bottom of the label is your Vehicle Identification Number (VIN). Gross Vehicle Weight Rating (GVWR) The GVWR is the total permissible weight of your vehicle including driver, passengers, vehicle, options, and cargo. The label also specifies maximum capacities of front and rear axle systems. Total load must be limited so that GVWR is not exceeded. Payload The payload of a vehicle is defined as the allowable load weight a truck can carry including the weight of the driver, all passengers, options, and cargo. Gross Axle Weight Rating (GAWR) The GAWR is the maximum permissible load on the front and rear axles. The load must be distributed in the cargo area so that the GAWR of each axle is not exceeded. Each axle GAWR is determined by the component in the system with the lowest load carrying capacity (axle, springs, tires, or wheels).

192 STARTING AND OPERATING

Heavier axles or suspension components sometimes specified by purchasers for increased durability do not necessarily increase the vehicle’s GVWR. Tire Size This is the minimum allowable tire size for your vehicle. Replacement tires must be equal to the load capacity of this tire size. Rim Size This is the rim size that is appropriate for the tire size listed. Inflation Pressure (Cold) This is the cold tire inflation pressure for your vehicle for all loading conditions up to full GAWR. Curb Weight The curb weight of a vehicle is defined as the total weight of the vehicle with all fluids, including vehicle fuel, at full capacity conditions, and with no occupants or cargo loaded into the vehicle. The front and rear curb weight values are determined by weighing your vehicle on a commercial scale before any occupants or cargo are added.

Loading The actual total weight and the weight of the front and rear of your vehicle at the ground can best be determined by weighing it when it is loaded and ready for operation. The entire vehicle should first be weighed on a commer- cial scale to insure that the GVWR has not been exceeded. The weight on the front and rear of the vehicle should then be determined separately to be sure that the load is properly distributed over front and rear axle. Weighing the vehicle may show that the GAWR of either the front or rear axles has been exceeded but the total load is within the specified GVWR. If so, weight must be shifted from front to rear or rear to front as appropriate until the specified weight limitations are met. Store heavier items down low and be sure that the weight is distributed equally. Stow all loose items securely before driving. Improper weight distribution can have an adverse effect on the way your vehicle steers and handles and the way the brakes operate.

WARNING!

Gross Vehicle Weight Rating (GVWR) 6500 LBS.

STARTING AND OPERATING 193

Do not load your vehicle any heavier than the GVWR or the maximum front and rear GAWR. If you do, parts on your vehicle can break, or it can change the way your vehicle handles. This could cause you to lose control. Also, overloading can shorten the life of your vehicle.

A loaded vehicle is shown in the following example. Note that neither GVWR nor GAWR capabilities are exceeded. Overloading can cause potential safety hazards and shorten service life. NOTE: The weights shown in this chart are not necessarily the weights for your vehicle. Also, the amount of load added to both the front and rear axles can be computed after the vehicle has been weighed both in its (curb weight( condition, and in its (loaded and ready for operation( condition.

194 STARTING AND OPERATING

LOADING WIDE BUILDING MATERIALS Four foot wide building materials can be conveniently carried in the Dakota pickup box. For occasional use up to 600 lbs (272 kg) of unrestrained material [9 pcs. 3/49
(19 mm) plywood] can be supported on 2 X 6 lumber placed crossbody in indentations provided in the pickup box inner walls. See illustration.

WARNING!

† Care should always be exercised when operating a vehicle with unrestrained cargo. Vehicle speeds may need to be reduced. Severe turns or rough roads may cause shifting or bouncing of the cargo that may result in vehicle damage. If wide build- ing materials are to be frequently carried, the installation of a support is recommended. This will restrain the cargo and transfer the load to the pickup box floor. † If you wish to carry more than 600 lbs (272 kg) of material suspended above the wheelhouse, sup- ports must be installed to transfer the weight of the load to the pickup box floor or vehicle damage may result. The use of proper supports will permit loading up to the rated payload. † Unrestrained cargo may be thrown forward in an

accident causing serious or fatal injury.

See your dealer or a reputable installer of aftermarket equipment for further information on the installation of these supports.

WARNING!

It is extremely dangerous to ride in a cargo area, inside or outside of a vehicle. In a collision, people riding in these areas are more likely to be seriously injured or killed. Do not allow people to ride in any area of your vehicle that is not equipped with seats and seat belts. Be sure every one in your vehicle is in a seat and using a seat belt properly

TRAILER TOWING To maintain warranty coverage, follow the requirements and recommendations in this manual concerning ve- hicles used for trailer towing. Definitions The following trailer towing related terminology defini- tions will assist in understanding the subsequent sec- tions: GROSS COMBINATION WEIGHT RATING (GCWR) is the total permissible weight of your vehicle and trailer when weighed in combination. (Note that GCWR ratings include a 68 kg (150 lb.) allowance for the presence of a driver.) Tongue Weight (of a trailer) is the weight placed on a vehicle’s trailer hitch by the trailer. GROSS TRAILER WEIGHT (GTW) is the weight of the trailer plus the weight of all cargo, consumables and equipment (permanent or temporary) loaded in or on the trailer in its 9loaded and ready for operation9 condition. TRAILER SWAY CONTROL is a telescoping link that can be installed between the hitch receiver and the trailer

196 STARTING AND OPERATING

tongue that typically provides adjustable friction associ- ated with the telescoping motion to dampen any un- wanted trailer swaying motions while traveling.

CAUTION!

† During the first 500 miles (805 km) your new vehicle is driven, do not tow a trailer. Doing so may damage your vehicle. † When first towing a trailer, limit your speed to 50
mph (80 km/h) during the first 500 miles (805 km) of towing.

Consider the following items when computing the weight on the rear axle: † the tongue weight of the trailer † the weight of any other type of cargo or equipment put

in or on your vehicle

NOTE: Remember that everything put into or on the trailer adds to the load on your vehicle. Also, additional factory-installed options, or dealer-installed options, must be considered as part of the total load on your vehicle. Refer to the Certification label located at the driver’s door for the Gross Vehicle Weight Rating. Perform maintenance services as prescribed in the Main- tenance Schedules section. When your vehicle is used for trailer towing, never exceed the gross axle weight rating (GAWR) and GVWR.

WARNING!

Improper towing can lead to an injury accident. Follow these guidelines to make your trailer towing as safe as possible: † Be sure the trailer is loaded heavier in front, with 60% to 65% of the weight located ahead of the trailer’s axles(s) sufficiently to place result in tongue weights of between 10% and 15% of the GTW loaded trailer weight on the tow hitch of your vehicle. (For a 95th

Wheel9 style trailer, this range of loading on the 9King Pin9 should be between 15% and 25%.) Loads balanced over the wheels or biased toward 9heavier in the rear9
can cause the trailer to sway severely side to side which will cause loss of control of vehicle and trailer. Failure to load trailers heavier in front is the cause of many trailer accidents. † Do not interconnect the hydraulic brake system of your vehicle with that of the trailer. This could cause inadequate braking and possible personal injury. † Trailer brakes are recommended for trailers over 1,000
lbs. (454 kg) and required for trailers in excess of 2,000
lbs. (907 kg). † Use an approved trailer harness and connector. If a hitch is ordered, the proper wiring will be provided. † When hauling cargo or towing a trailer, do not over- load your vehicle or trailer. Overloading can cause a loss of control, poor performance or damage to brakes, axle, engine, transmission, steering, suspension, chas- sis structure or tires.

STARTING AND OPERATING 197

† Make certain that the load is secured in the trailer and will not shift during travel. When trailering cargo that cannot be fully secured, dynamic load shifts can occur that may be difficult for the driver to control. † All trailer hitches should be professionally installed on † Safety chains must always be used between your † Connect trailer lighting and brakes using factory har- nesses only.

vehicle and trailer.

your vehicle.

Trailer and Tongue Weight Gross Trailer Weight (GTW) means the weight of the trailer plus the weight of all cargo and equipment loaded on the trailer when in actual underway towing condition. The recommended way to measure GTW is to put your fully loaded trailer on a vehicle scale. The entire weight of the trailer must be supported by the scale. Tongue Weight is the weight placed on the vehicle’s trailer hitch by the trailer. Always load a trailer with 60%

198 STARTING AND OPERATING

to 65% of the weight in the front of the trailer. This places 10% to 15% of the GTW on the tow hitch of your vehicle.

Trailer sway control and equalizing hitch are required for tongue weights above 350 lbs. (159 kg). Trailer Towing—Hitches: With a Class I Hitch, your vehicle can be equipped to tow trailers with a Gross Trailer Weight (GTW) of 2,000 lbs. (907 kg) maximum. Vehicles equipped with a rear step bumper are rated for a Class I Hitch.

With a Class II Hitch, your vehicle can be equipped to tow trailers with a Gross Trailer Weight (GTW) of 3,500
lbs. (1,587 kg) maximum. Tongue weight must be equal to at least 10% of GTW, but no more that 15% of GTW. With a Class III Hitch, your vehicle can be equipped to tow trailers with a Gross Trailer Weight (GTW) of 5,000
lbs. (2,268 kg) maximum. Tongue weight must be equal to at least 10% of GTW, but no more that 15% of GTW. With a Class IV Hitch, you can tow a trailer with a Gross Trailer Weight of up to 6,700 lbs. (3039 kg.) depending on your vehicle equipment. The Trailer Tow Package in- cludes the platform hitch receiver, and a 7 lead wiring harness mounted on the hitch. NOTE: When towing a trailer, the following require- ments must be adhered to: † GCWR must not be exceeded † Total weight must be distributed between the tow vehicle and the trailer such that the following four (4) ratings are not exceeded: 1. GVWR

2. GTW 3. Tongue weight rating for the trailer hitch uti- lized (This requirement may limit the ability to always achieve the 10% to 15% range of tongue weight [15% to 25% for a (5th Wheel( style trailer] as a percentage of total trailer weight.) 4. GAWR ratings

NOTE: Towing a trailer equipped with more than the standard lighting (turn, tail, stop and backup lights) may cause an abnormally high electrical current draw through the headlight switch, causing the switch to fail. To prevent a recurring switch failure install a trailer tow wiring harness overlay kit with relay to bypass headlight switch (available from your dealer).

Trailer Towing Requirements All Dodge Dakota trucks are intended to tow trailers up to 2,000 lbs. without added equipment or alterations to standard equipment. Your vehicle may be factory equipped for safe towing of trailers weighing over 2,000
lbs. with the Trailer Tow Package. The electrical part of this package includes an instruction sheet, a 7/4 pin adaptor, a wiring pigtail for an aftermarket electric trailer brake controller, and three relays that must be installed into the power distribution center. These items are stored in the glove box. Also included in the Trailer Tow Package are two fuses and a relay that are located on the driver’s side of the engine compartment on a harness near the Power Distribution Center. This relay and the fuses power up the trailer towing option. See your Dodge dealer for further information. If you regularly pull a trailer, regardless of the trailer size, stop and turn signals on the trailer are recommended for motoring safety. To handle the additional electrical load

200 STARTING AND OPERATING

of the trailer lights and assure their proper functioning, a heavy duty turn signal flasher can be installed as a separate equipment item by your dealer.

WARNING!

The direct connection of hydraulic brake lines from vehicle brake system to trailer system is not accept- able. The extra load may cause brake failure and you may be injured.

Heavy trailer towing also may require breakaway electric trailer brakes, anti-sway devices or equalizing hitches for safe operation. Such devices are commonly required by state law. For all trailer tow or heavy-duty applications it is strongly recommended that the factory fill rear axle lubricant be replaced with an SAE 75W-140 synthetic gear lubricant. Mopart Synthetic Gear Lubricant is of this type.

Trailer Tow Wiring The Trailer Tow Package includes a wiring harness located at the rear underbody of the vehicle. NOTE: Connect trailer lighting and brakes using fac- tory harnesses only. Do not cut or splice wiring to the brake circuits. The electrical connections are all complete to the vehicle but you must mate the harness to a trailer connector.

WARNING!

You or others could be injured if you leave the vehicle unattended with the transfer case in the Neutral (N) position without first fully engaging the parking brake. The transfer case Neutral (N) position disengages both the front and rear driveshafts from the powertrain and will allow the vehicle to move despite the transmission position. The parking brake should always be applied when the driver is not in the vehicle.

206 STARTING AND OPERATING

TRACTION When driving on wet or slushy roads, it is possible for a wedge of water to build up between the tire and road surface. This is known as hydroplaning and may cause partial or complete loss of vehicle control and stopping ability. To reduce this possibility, the following precau- tions should be observed: 1. Slow down during rainstorms or when roads are slushy. 2. Slow down if road has standing water or puddles. 3. Replace tires when tread wear indicators first become visible. 4. Keep tires properly inflated. 5. Maintain sufficient distance between your vehicle and the car in front to avoid a collision in a sudden stop.

EQUIPMENT IDENTIFICATION PLATE The equipment Identification Plate is located on the hood inner surface. The following information about your vehicle is dis- played on this plate: Model, Wheelbase, Vehicle Identifi- cation Number, Truck Order Number, and code numbers with descriptions of all production and special equip- ment on the truck as shipped from the factory.

HAZARD WARNING FLASHER The flasher switch is on the top of the steering column, just behind the steering wheel. Press the flasher switch and all front and rear directional signals will flash intermittently. Press the switch a second time to turn off the emergency flashers.

This is an emergency warning system and should not be used when the vehicle is in motion. Use it when your vehicle is disabled and is creating a safety hazard for other motorists.

If it is necessary to leave the vehicle to go for service, the flasher system will continue to operate with the ignition key removed and the vehicle locked.

ADDING FUEL On some models, the fuel tank filler tube, on vehicles equipped with a catalytic converter, has a restricting door about 2 inches (50 mm) inside the opening. If using a portable fuel container, it should have a flexible nozzle long enough to force open the restricting door.

WARNING!

A fire may result if gasoline is pumped into a portable container that is in a vehicle or on a truck bed. You could be burned. Always place gas contain- ers on the ground while filling.

WARNING!

CHANGING A FLAT TIRE

WHAT TO DO IN EMERGENCIES 209

Remove the gas cap slowly to prevent fuel spray from the filler neck which may cause injury. The volatility of present gasolines may cause a build up of pressure in the fuel tank that may increase while you drive. This pressure can result in a spray of gasoline and/or vapors when you remove the cap from a hot vehicle. Removing the cap slowly allows the pressure to vent and prevents fuel spray. Never allow any lit smoking materials near the vehicles while removing the cap or filling the tank. Never add fuel to the vehicle when the engine is running.

Jack Location The jack, jack drive tube, 2 tube extensions, and wheel wrench are located behind the seat on the passenger’s side of the vehicle.

WARNING!

The jack is designed as a tool for changing tires only. The jack should not be used to lift the vehicle for service purposes, unless suitable supports are placed under the vehicle as a safety measure. The vehicle should be jacked on a firm level surface only. Avoid ice or slippery areas. † In the Regular Cab the jack and tools are stowed under a formation in the carpet behind the passenger seat. † In the Quad Cab the jack and tools are stowed under the rear seat. Lift the passenger side rear seat cushion to gain access to this area.

210 WHAT TO DO IN EMERGENCIES

† In the Club Cab the jack and tools are stowed in a floor compartment located under the rear seat on the pas- senger’s side of the vehicle. The seat cushion can be lifted to a vertical position to allow access to this compartment.

Tire Changing Procedure

WARNING!

Getting under a jacked-up vehicle is dangerous. The vehicle could slip off the jack and fall on you. You could be crushed. Never get any part of your body under a vehicle that is on a jack. Never start or run the engine while the vehicle is on a jack. If you need to get under a raised vehicle, take it to a service center where it can be raised on a lift.

Do not raise this vehicle using a bumper jack. The jack is designed as a tool for changing tires on this vehicle only. It is not recommended that the jack be used for service purposes or to lift more than one wheel at a time. Preparations Park the vehicle on a firm level surface, avoiding ice or slippery areas. Set the parking brake and place the gear selector in PARK (automatic transmission) or REVERSE (manual transmission). On four-wheel drive vehicles, shift the transfer case to the “4L” position.

212 WHAT TO DO IN EMERGENCIES

WARNING!

Do not attempt to change a tire on the side of the vehicle close to moving traffic. Pull far enough off the road to avoid the danger of being hit when operating the jack or changing the wheel. † Turn on the Hazard Warning Flasher.

† Block both the front and rear of the wheel diagonally oppo- site the jacking position. For example, front wheel is being changed, block the left rear wheel. † Passengers should not remain in the vehicle when the

vehicle is being jacked.

Instructions 1. Remove the spare wheel, jack, and tools from storage. 2. Remove wheel center cap using the spade end of the wheel wrench. 3. Using the wheel wrench, loosen, but do not remove, the wheel nuts by turning them counterclockwise one turn while the wheel is still on the ground. 4. When changing a front wheel, place the jack under the frame rail behind the wheel. Locate the jack as far forward as possible on the straight part of the frame. Make sure that the upstanding tab of the jack contacts the vertical side of the frame. Operate the jack using the jack drive tube and the wheel wrench— the tube extension, may be used but is not required. When changing a rear wheel, assemble the jack drive tube to the jack and connect the drive tube to the extension tube. Place the jack under the axle between the spring and the shock absorber with the drive tubes extending to the rear. Connect the jack tube extension and wheel wrench.

Before raising the wheel off the ground, make sure that the jack will not damage surrounding truck parts and adjust the jack position as required.

5. By rotating the wheel wrench clockwise, raise the vehicle until the wheel just clears the surface.

WHAT TO DO IN EMERGENCIES 213

WARNING!

Raising the vehicle higher than necessary can make the vehicle unstable and cause an accident. It could slip off the jack and hurt someone near it. Raise the vehicle only enough to remove the tire.

6. Remove the wheel nuts and pull the wheel off. Install the spare wheel and wheel nuts with the cone shaped end of the nuts toward the wheel. Lightly tighten the nuts. To avoid risk of forcing the vehicle off the jack, do not fully tighten the nuts until the vehicle has been lowered. 7. Using the wheel wrench, finish tightening the nuts in a crisscross pattern.Correct nut tightness is 85-115 ft. lbs. (115-155 N·m) torque. If in doubt about the correct tightness, have them checked with a torque wrench by your dealer or at a service station.

JUMP STARTING

WARNING!

† Battery fluid is a corrosive acid solution; do not allow battery fluid to contact eyes, skin or cloth- ing. Don’t lean over battery when attaching clamps or allow the clamps to touch each other. If acid splashes in eyes or on skin, flush the con- taminated area immediately with large quantities of water. † A battery generates hydrogen gas which is flam- mable and explosive. Keep flame or spark away from the vent holes. Do not use a booster battery or any other booster source with an output that exceeds 12 volts.

Check the Battery Test Indicator (if equipped). If a yellow or bright colored dot is visible in the indicator (if equipped), DO NOT jump-start the battery.

216 WHAT TO DO IN EMERGENCIES

If the indicator (if equipped) is dark or shows a green dot, proceed as follows: 1. Wear eye protection and remove all metal jewelry such as watch bands or bracelets which might make an unintended electrical contact. 2. Park the booster vehicle within cable reach but with- out letting the vehicles touch. Set the parking brake, place the automatic transmission in PARK or the manual transmission in NEUTRAL and turn the ignition OFF on both vehicles. 3. Turn OFF heater, radio and all unnecessary electrical loads. 4. Connect one end of a jumper cable to the positive terminal of the booster battery. Connect the other end of the same cable to the positive terminal of the discharged battery.

WARNING!

Do not permit vehicles to touch each other as this could establish a ground connection and personal injury could result.

5. Connect the other cable, first to the negative terminal of the booster battery and then to the engine of the vehicle with the discharged battery. Make sure you have a good contact on the engine.

WHAT TO DO IN EMERGENCIES 217

WARNING!

WARNING!

Do not connect the cable to the negative post of the discharge battery. The resulting electrical spark could cause the battery to explode. During cold weather when temperatures are below freezing point, electrolyte in a discharged battery may freeze. Do not attempt jump starting because the battery could rupture or explode. The battery temperature must be brought up above freezing point before attempting jump start.

6. Start the engine in the vehicle which has the booster battery, let the engine idle a few minutes, then start the engine in the vehicle with the discharged battery. 7. When removing the jumper cables, reverse the above sequence exactly. Be careful of the moving belts and fan.

Any procedure other than above could result in: 1. Personal injury caused by electrolyte squirting out the battery vent; 2. Personal injury or property damage due to battery explosion; 3. Damage to charging system of booster vehicle or of immobilized vehicle.

TOWING A DISABLED VEHICLE Proper towing or lifting equipment is required to prevent damage to your vehicle. Use of safety chains is recom- mended. Attach towing device to main structural mem- bers of the vehicle — not to bumpers or associated brackets. State and local laws applying to vehicles under tow must be observed.

If the vehicle is to be towed more than 15 miles (25 km), it must be towed on a flatbed, or with the rear wheels raised and the front wheels on the ground, or with the front end raised and the rear wheels on a towing dolly.

218 WHAT TO DO IN EMERGENCIES

Four-Wheel Drive Vehicles The manufacturer recommends towing with all wheels off the ground. Acceptable methods are to tow the vehicle on a flatbed or with one end of the vehicle raised and the opposite end on a towing dolly. Two-Wheel Drive Vehicles

Provided that the transmission is operable, tow with the transmission in Neutral and the ignition key in the OFF position along with the front wheels raised and the rear wheels on the ground. The speed must not exceed 30
mph (50 km/h) and the distance must not exceed 15
miles (25 km).

ENGINE COMPARTMENT 4.7L V-8

ONBOARD DIAGNOSTIC SYSTEM — OBD II Your vehicle is equipped with a sophisticated onboard diagnostic system called OBD II. This system monitors the performance of the emissions, engine, and automatic transmission control systems. When these systems are operating properly, your vehicle will provide excellent performance and fuel economy, as well as engine emis- sions well within current government regulations. If any of these systems require service, the OBD II system will turn on the “Malfunction Indicator Light.” It will also store diagnostic codes and other information to assist your service technician in making repairs. Al- though your vehicle will usually be drivable and not need towing, see your dealer for service as soon as possible.

MAINTAINING YOUR VEHICLE 223

CAUTION!

† Prolonged driving with the “Malfunction Indica- tor Light” on could cause further damage to the emission control system. It could also affect fuel economy and driveability. The vehicle must be serviced before any emissions tests can be per- formed. † If the “Malfunction Indicator Light” is flashing while the engine is running, severe catalytic con- verter damage and power loss will soon occur. Immediate service is required.

224 MAINTAINING YOUR VEHICLE

EMISSIONS INSPECTION AND MAINTENANCE PROGRAMS In some localities, it may be a legal requirement to pass an inspection of your vehicle’s emissions control system. Failure to pass could prevent vehicle registration.

For states which have an I/M (Inspection and Maintenance) requirement, this check verifies the following: the MIL (Malfunction Indicator Lamp) is functioning and is not on when the engine is running, and that the OBD (On Board Diagnostic) system is ready for testing. Normally, the OBD system will be ready. The OBD system may not be ready if your vehicle was recently serviced, if you recently had a dead battery, or a battery replacement. If the OBD system should be determined not ready for the I/M test, your vehicle may fail the test. Your vehicle has a simple ignition key actuated test which you can use prior to going to the test station. To check if your vehicle’s OBD system is ready, you must do the following: 1. Insert your ignition key into the ignition switch.

2. Turn the ignition to the ON position, but do not crank or start the engine. 3. If you crank or start the engine, you will have to start this test over. 4. As soon as you turn your key to the ON position, you will see your MIL symbol come on as part of a normal bulb check. 5. Approximately 15 seconds later, one of two things will happen:

a. The MIL light will blink for approximately 5
seconds and then remain on until the first engine crank or the key is turned off. This means that your vehicle’s OBD system is not ready and you should not proceed to the I/M station. b. The MIL light will remain fully illuminated until the first engine crank or the key is turned off. This means that your vehicle’s OBD system is ready and you can proceed to the I/M station.

If your OBD system is not ready, you should see your dealer or repair facility. If your vehicle was recently

serviced or had a battery failure or replacement, you may need to do nothing more than drive your vehicle as you normally would in order for your OBD system to update. A recheck with the above test routine may then indicate that the system is now ready. Regardless of whether your vehicle’s OBD system is ready or not ready, if the MIL symbol is illuminated during normal vehicle operation, you should have your vehicle serviced before going to the I/M station. The I/M station can fail your vehicle because the MIL symbol is on with the engine running.

REPLACEMENT PARTS Use of genuine Mopart parts for normal/scheduled maintenance and repairs is highly recommended to in- sure the designed performance. Damage or failures caused by the use of non-Mopart parts for maintenance and repairs will not be covered by the manufacturer’s warranty.

MAINTAINING YOUR VEHICLE 225

DEALER SERVICE Your dealer has the qualified service personnel, special tools and equipment to perform all service operations in an expert manner. Service manuals are available which include detailed service information for your vehicle. Refer to these manuals before attempting any procedure yourself. NOTE: systems can result against you.
