CASSETTE TAPE AND PLAYER MAINTENANCE To keep the cassette tapes and player in good condition, take the following precautions: 1. Do not use cassette tapes longer than C-90; otherwise, sound quality and tape durability will be greatly dimin- ished. 2. Keep the cassette tape in its case to protect from slackness and dust when it is not in use. 3. Keep the cassette tape away from direct sunlight, heat and magnetic fields such as the radio speakers. 4. Before inserting a tape, make sure that the label is adhering flatly to the cassette.

UNDERSTANDING YOUR INSTRUMENT PANEL 183

5. A loose tape should be corrected before use. To rewind a loose tape, insert the eraser end of a pencil into the tape drive gear and twist the pencil in the required directions. Maintain your cassette tape player. The head and capstan shaft in the cassette player can pick up dirt or tape deposits each time a cassette is played. The result of deposits on the capstan shaft may cause the tape to wrap around and become lodged in the tape transport. The other adverse condition is low or “muddy” sound from one or both channels, as if the treble tone control were turned all the way down. To prevent this, you should periodically clean the head with a commercially available WET cleaning cassette. As preventive maintenance, clean the head about every 30 hours of use. If you wait until the head becomes very dirty (noticeably poor sound), it may not be possible to remove all deposits with a simple WET cleaning cassette.

184 UNDERSTANDING YOUR INSTRUMENT PANEL

COMPACT DISC MAINTENANCE To keep the compact discs in good condition, take the following precautions: 1. Handle the disc by its edge; avoid touching the surface. 2. If the disc is stained, clean the surface with a soft cloth, wiping from center to edge. 3. Do not apply paper or tape to the disc; avoid scratch- ing the disc. 4. Do not use solvents such as benzene, thinner, cleaners, or antistatic sprays. 5. Store the disc in its case after playing. 6. Do not expose the disc to direct sunlight. 7. Do not store the disc where temperatures may become too high.

If you experience difficulty in playing a particu- NOTE: lar disc, it may be damaged, oversized, or have theft protection encoding. Try a known good disc before considering disc player service.

RADIO OPERATION AND CELLULAR PHONES Under certain conditions, the operation of a cellular phone in your vehicle can cause erratic or noisy perfor- mance from your radio. This condition may be lessened or eliminated by relocating the cellular phone antenna. This condition is not harmful to the radio. If your radio performance does not satisfactorily “clear” by the repo- sitioning of the antenna, it is recommended that the radio volume be turned down or off during cellular phone operation.

Fast Cooldown For a fast cooldown, turn the blower fan rotary knob to the extreme right position, turn the mode control to the panel fresh position, press the snowflake button to turn on the air conditioning, and drive with the windows open for the first few minutes. Once the hot air has been expelled, close the windows and press the Recirculation pushbutton. When a comfortable condition has been

reached, choose a mode position and adjust the tempera- ture control slide and blower speed as necessary to maintain comfort. For high humidity conditions it may be necessary to remain in the Recirculation mode to maintain comfort. Window Fogging Windows will fog on the inside when the humidity inside the vehicle is high. This often occurs in mild or cool temperatures when it’s rainy or humid. In most cases turning on the Air-conditioning (pressing the snowflake button) will clear the fog. Adjust the temperature control, air direction and blower speed to maintain comfort. As the temperature gets colder it may be necessary to direct air onto the windshield by using MIX Mode position on the control. Adjust the temperature control and blower speed to maintain comfort. Higher blower

speeds will reduce fogging. Interior fogging on the windshield can be quickly removed by selecting the defrost mode. Regular cleaning of the inside of the windows with a non-filming cleaning solution (vinegar and water works very well) will help prevent contaminates (cigarette smoke, perfumes, etc.) from sticking to the windows. Contaminates increase the rate of window fogging. Summer Operation Air conditioned vehicles must be protected with a high quality antifreeze coolant during summer to provide proper corrosion protection and to raise the boiling point of the coolant for protection against overheating. A 50 % concentration is recommended. Refer to Recommended Fluids and Genuine Parts for the proper coolant type. When using the air conditioner in extremely heavy traffic in hot weather especially when towing a trailer, addi- tional engine cooling may be required. If this situation is

encountered, operate the transmission in a lower gear to increase engine RPM, coolant flow and fan speed. When stopped in heavy traffic, it may be necessary to shift into NEUTRAL and depress the accelerator slightly for fast idle operation to increase coolant flow and fan speed. NOTE: On models equipped with Diesel engines, the idle speed will automatically increase to 1000 rpm at elevated coolant temperatures to improve engine cooling. Your air conditioning system is also equipped with an automatic recirculation system. When the system senses a heavy load or high heat conditions, it may use partial Recirculation A/C mode to provide additional comfort. Winter Operation When operating the system during the winter months, make sure the air intake, located directly in front of the windshield, is free of ice, slush, snow, or other obstruc- tions.

204 STARTING AND OPERATING

IGNITION/STARTER SWITCH

LOCK Locks the automatic transmission shift control into the PARK position. It also engages the steering wheel lock (if equipped) when the steering wheel is turned.

NOTE: This vehicle is equipped with a transmission shift interlocking system. The brake pedal must be depressed to shift out of Park (P). OFF Unlocks the steering wheel (if equipped with locking wheel) and the automatic transmission shift control with engine off. ON This is the normal running position. START Starts the engine. When the engine starts, release the key. The ignition key will return to the ON position for normal driving.

ACC Allows the electrical accessories to be used when the engine is not running. Manual Transmission Key Release Button

To remove the key on vehicles equipped with manual transmissions, turn the key to the Lock position and press the button to remove the ignition key.

STARTING AND OPERATING 205

Key Reminder An alarm will sound to remind you if the key is left in the ignition and the driver’s door is opened.

STARTING PROCEDURES The Cummins Diesel engine is equipped with several features designed to assist cold weather starting and operation: † The engine block heater is a resistance heater installed in the water jacket of the engine just above and behind the oil filter. It requires a 110–115 volt AC electrical outlet with a grounded, three-wire extension cord.

NOTE: The engine block heater cord is a factory in- stalled option. If your vehicle is not equipped, heater cords are available from your authorized Mopart dealer. † A 12–volt heater built into the fuel filter housing aids in preventing fuel gelling. It is controlled by a built-in thermostat.

206 STARTING AND OPERATING

† A heated intake air system both improves engine starting and reduces the amount of white smoke generated by a warming engine.

Normal Starting Procedure — Engine Manifold AirTemperature Above 66°F (19°C) Observe the Instrument Panel Cluster lights when start- ing the engine. 1. Always apply the parking brake. 2. Shift into PARK for an automatic transmission. Fully depress and hold the clutch and shift into NEUTRAL for a manual transmission. Models with manual transmis- sion are equipped with a clutch interlocking cranking system. The clutch must be fully depressed to start the vehicle. 3. Turn the ignition key to the ON position and look at the instrument panel cluster lamps.

The lamps in the instrument panel cluster will illuminate when the ignition key is first turned to the ON position. This is a bulb check programmed to last for approxi- mately 3 seconds. After the bulb check is completed, the Malfunction Indicator Light and Brake Warning light will remain on. After the bulb check is complete and the WAIT TO START indicator goes out proceed to step 4.

CAUTION!

If WATER IN FUEL indicator light remains on DO NOT START engine before you drain water from the fuel filter to avoid engine damage. See Section 7 — Maintaining Your Vehicle, for water drain proce- dures.

4. Turn the ignition key to START and crank the engine. Do not press the accelerator during starting.

CAUTION!

Do not crank engine for more than 15 seconds at a time as starter motor damage may result. Turn key to OFF and wait at least two minutes before trying again.

5. When the engine starts, release the key. 6. Check to see that there is oil pressure. 7. Release the parking brake. Starting Procedure — Engine Manifold Air Temperature Below 66°F (19°C)

NOTE: The temperature displayed on the overhead console (if equipped) does not necessarily reflect the engine manifold air temperature. The wait-to-start lamp will illuminate momentarily for a bulb check when the ignition key is turned to the ON position, however when

STARTING AND OPERATING 207

certain engine temperatures fall below 66°F (19°C) the lamp will remain on indicating the intake manifold heater system is active. Follow the steps in the Normal Starting Procedure ex- cept:

CAUTION!

Do not crank engine for more than 15 seconds at a time or starter motor damage may result. Turn key to OFF and wait at least 2 minutes for starter to cool before repeating start procedure. † The WAIT TO START light will remain on for a period of time (length of time depends on engine tempera- ture) after completion of the bulb check.

208 STARTING AND OPERATING

† After the WAIT TO START light goes off, turn the ignition key to START. Do not press the accelerator during starting. † Check to see that there is oil pressure. † Allow the engine to idle at fast idle for about three minutes until the manifold heaters have completed the post-heat cycle.

† Release the parking brake and drive. NOTE: Engine idle speed will automatically increase to 1000 rpm at low coolant temperatures to improve engine warm-up. If the engine stalls or if the ignition switch is left NOTE: On for more than 2 minutes after the WAIT TO START light goes out, reset the grid heaters by turning the ignition switch to Off and the back On. Repeat steps 3
through 7 of the normal starting procedure.

For Extremely Cold Weather Starting (Engine Temperature Below 0°F (- 18°C) In extremely cold weather below 0°F (- 18°C) it may be beneficial to cycle the manifold heaters twice before attempting to start the engine. This can be accomplished by turning the ignition OFF and then back ON after the WAIT TO START light has gone off, but before the engine is started. However, repeated cycling of the manifold heaters will result in damage to the heater elements or reduced battery voltage. NOTE: If multiple pre-heat cycles are used before starting, additional engine run time may be required to maintain battery state of charge at a satisfactory level. † If the engine stalls after the initial start, the ignition must be turned to the OFF position and then to the ON position to recycle the manifold heaters.

NOTE: Excessive white smoke and poor engine perfor- mance will result if manifold heaters are not recycled.

† Heat generated by the manifold heaters dissipates rapidly in a cold engine. If more than two minutes pass between the time the WAIT TO START light goes OFF and the engine is started, recycle the manifold heaters by turning the ignition OFF and then back ON. † If the vehicle is driven and vehicle speed exceeds 18
mph (29 km) before the manifold heater post-heat (after start) cycle is complete, the manifold heaters will shut off. † If the engine is started before the WAIT TO START † If the engine is cranked for more than 10 seconds, the

light turns off, the preheat cycle will turn off.

post-heat cycle will turn off.

NOTE: Engine idle speed will automatically increase to 1000 rpm at low coolant temperatures to improve engine warm-up.

STARTING AND OPERATING 209

NOTE: When a diesel engine is allowed to run out of fuel or the fuel gels at low temperatures, air is pulled into the fuel system. You may try priming as described below. 1. Add a substantial quantity of fuel to the tank (5 to 10
gallons) or eliminate the gelled fuel condition. 2. Crank the engine for 1 to 2 seconds. If the engine does not start, then release the key or starter button back to the RUN position (do not turn the key back to the OFF position). The electric fuel transfer pump will continue to run and purge air from the system for about 25 seconds. After 25 seconds, attempt to start the engine again. 3. Start the engine using the Normal Starting Procedure. 4. Repeat the procedure if the engine does not start.

210 STARTING AND OPERATING

WARNING!

Starting Fluids

Do not open the high pressure fuel system with the engine running. Engine operation causes high fuel pressure. High pressure fuel spray can cause serious injury or death.

NOTE: The engine may run rough until the air is forced from all the fuel lines.

WARNING!

STARTING FLUIDS or flammable liquids are NEVER TO BE USED in the Cummins Diesel (see Warning label). Never pour diesel fuel, flammable liquid, starting fluids (ether) into the air cleaner canister, air intake piping, or turbocharger inlet in an attempt to start the vehicle. This could result in a flash fire and explosion causing serious personal injury and engine damage.

The engine is equipped with an automatic electric air preheating system. If the instructions in this manual are followed, the engine should start in all conditions.

STARTING AND OPERATING 211

cycle of the intake manifold heater system. The number of cycles and the length of the cycling operation is controlled by the engine control mod- ule, this time will not exceed 150 seconds. The needle should then stabilize at the approximate operation point. † The cycling action will cause temporary dimming of the headlamps, interior lamps, and also a noticeable reduction in blower motor speed.

Cold Weather Precautions Operation in ambient temperature below 32°F (0°C) may require special considerations. The following charts sug- gest these options:

WARNING!

Do not leave children or animals inside parked vehicles in hot weather. Interior heat build up may cause serious injury or death.

NORMAL OPERATION Observe the following when the engine is operating. † All message center lights are off. † Check Engine Lamp is off. † Engine Oil Pressure is above 10 psi (69 kPa) at idle. † Low Oil Pressure light is off. † Voltmeter Operation: † The voltmeter may show a gauge fluctuation if certain engine temperatures are below 66°F (19°C). This cycling operation is caused by the post-heat

Fuel Operating Range

*No. 1 diesel fuel should only be used where extended arctic conditions (-10°F/-23°C) exist. NOTE: † Use of Climatized Diesel Fuel or Number 1 Diesel Fuel † Climatized Diesel Fuel is a blend of Number 2 and Number 1 Diesel Fuels which reduces the temperature at which wax crystals form in fuel.

results in a noticeable decrease in fuel economy.

NOTE: Refer to Fuel Requirements in this section for further details on fuel recommendations. Engine Block Heater The engine block heater warms engine coolant and permits quicker starts in cold weather. Connect the heater cord to a ground–fault interrupter protected 110–115 volt AC electrical outlet with a grounded, three-wire exten- sion cord. The engine block heater cord is routed under the hood to the right side and can be located just behind the grille near the headlamp. NOTE: The engine block heater cord is a factory in- stalled option. If your vehicle is not equipped, heater cords are available from your authorized Mopart dealer. The block heater must be plugged in at least one hour to have an adequate warming effect on the coolant.

WARNING!

Remember to disconnect the cord before driving. Damage to the 110–115 volt electrical cord could cause electrocution.

NOTE: The block heater will require 110 Volts AC and 6.5 Amps to activate the heater element. Block Heater Usage A. Temperatures below 0°F (-18°C) † Block Heater Required for 15W-40
† Block Heater Recommended for 5W-40
B. Temperatures below - 20°F (-29°C) † Block Heater Required for 5W-40

STARTING AND OPERATING 213

Winter Front Usage If a winter front or cold weather cover is to be used, a percentage of the total grille opening area must be left uncovered to provide sufficient air flow to the charge air cooler and automatic transmission oil cooler. The per- centage of opening must be increased with the increasing ambient air temperature and/or engine load. If the cooling fan can be heard cycling frequently, increase the size of the opening in the winter front. A suitable cold weather cover is available from your Mopart dealer. Battery Blanket Usage A battery loses 60% of its cranking power as the battery temperature decreases to 0°F (-18°). For the same de- crease in temperature, the engine requires twice as much power to crank at the same RPM. The use of 120 VAC powered battery blankets will greatly increase starting capability at low temperatures. Suitable battery blankets are available from your authorized Mopart dealer.

214 STARTING AND OPERATING

Arctic Operation Where there are no provisions to keep the engine warm when it is operating in ambient temperatures consistently below (-10°F/-23°C), use 5W-40 synthetic engine oil and fuel that meets the requirements in Section 7, “Mainte- nance Procedures,” Engine Oil Selection. Engine Warm-Up Avoid full throttle operation when the engine is cold. When starting a cold engine, bring the engine up to operating speed slowly to allow the oil pressure to stabilize as the engine warms up. NOTE: High-speed, no-load running of a cold engine can result in excessive white smoke and poor engine performance. No-load engine speeds should be kept under 1,200 rpm during the warm-up period, especially in cold ambient temperature conditions.

If temperatures are below 32°F (0°C), operate the engine at moderate speeds for 5 minutes before full loads are applied. Engine Idling — In Cold Weather Avoid prolonged idling. Long periods of idling may be harmful to your engine because combustion chamber temperatures can drop so low that the fuel may not burn completely. Incomplete combustion allows carbon and varnish to form on piston rings and injector nozzles. Also, the unburned fuel can enter the crankcase, diluting the oil and causing rapid wear to the engine. NOTE: † If ambient

temperatures are low and the coolant temperature is below 200°F (93°C), the engine idle speed will slowly increase to 1000 RPM after 2 minutes of idle, if the following conditions are met: † foot is off brake pedal and throttle pedal

† automatic transmission is in Park (P) † vehicle speed is zero † Applying the throttle will cancel fast idle † If the engine is equipped with an aftermarket exhaust brake (manual transmissions only), operating the ex- haust brake at idle will greatly improve warm up rate and will help keep the engine close to operating temperature during extended idle.

Stopping The Engine Idle the engine a few minutes before routine shutdown. After full load operation, idle the engine 3 to 5 minutes before shutting it down. This idle period will allow the lubricating oil and coolant to carry excess heat away from the combustion chamber, bearings, internal components, and turbocharger. This is especially important for turbo- charged, charge air cooled engines, like your Turbo Ram.

Engine Speed Control

CAUTION!

Prevent overspeeding the engine going down hill. When descending steep grades, use a combination of gears and service brakes to control vehicle/engine speed. Overspeed can cause severe engine damage.

Operating Precautions

Avoid Overheating The Engine The temperature of (a mixture of 50% the coolant ethylene-glycol and 50% water) must not exceed the normal range of the temperature gauge (240°F/116°C) with a 16 psi (110 kPa) radiator cap. Usually the coolant temperature indicated during opera- tion will be to the left of center in the normal range of the gauge.

Avoid Low Coolant Temperature Operation Continual operation at low coolant temperature below the normal range on the gauge (140°F/60°C) can be harmful to the engine. Low coolant temperature can cause incomplete combustion which allows carbon and varnish to form on piston rings and injector nozzles. Also, the unburned fuel can enter the crankcase, diluting the lubricating oil and causing rapid wear to the engine. Cooling System Tips — Automatic Transmission To reduce potential for engine and transmission over- heating in high ambient temperature conditions, take the following actions: † City Driving — when stopped, put transmission in neutral and increase engine idle speed. NOTE: The engine speed will automatically increase to 1000 RPM at elevated coolant temperature to improve engine cooling.

† Highway Driving — reduce your speed. † Up Steep Hills — select a lower transmission gear, but try and keep the torque converter locked. † Air Conditioning — turn it off temporarily. Do Not Operate The Engine With Low Oil Pressure When the engine is at normal operating temperature, the minimum oil pressures required are:

Idle 700 to 800 RPM . . . . . . . . . . . . . . . 10 psi (69 kPa) Full speed and load . . . . . . . . . . . . . . 30 psi (207 kPa)

STARTING AND OPERATING 217

CAUTION!

If oil pressure falls to less than normal readings, shut the engine off immediately. Failure to do so could result in immediate and severe engine damage.

Do Not Operate The Engine With Failed Parts Practically all failures give some warning before the parts fail. Be on the alert for changes in performance, sounds, and visual evidence that the engine requires service. Some important clues are: † engine misfiring or vibrating severely † sudden loss of power † unusual engine noises † fuel, oil or coolant leaks

218 STARTING AND OPERATING

the engine operating temperature

† sudden change, outside the normal operating range, in † excessive smoke † oil pressure drop TRANSMISSION SHIFTING

Four-Speed Overdrive Automatic Transmission — If Equipped The gear shift selector display, located in the instrument panel cluster, indicates the transmission gear range (the selector is illuminated for night driving). The selector lever is mounted on the right side of the steering column. You must depress the brake pedal, to pull the selector lever out of park (P) position (Brake Interlock System). To drive, move the selector lever from Park or Neutral to the desired drive position. Pull the selector lever toward you when shifting into Reverse, Second, First or Park, or when shifting out of Park.

Gear Ranges DO NOT race the engine when shifting from Park or Neutral position into another gear range. “P” Park This gear position supplements the parking brake by locking the transmission. The engine can be started in this range. Never use Park while the vehicle is in motion. Apply the parking brake when leaving the vehicle in this range. Always apply parking brake first, then place the selector in Park position. On 4-wheel drive vehicles be sure that the transfer case is in a drive position!

WARNING!

Your vehicle could move and injure you and others if it is not completely in P (Park). Check by trying to move the gearshift lever back and forth without first pulling it toward you after you have set it in P. Make sure it is in Park before leaving the vehicle.

WARNING!

It is dangerous to shift the selector lever out of “P” or “N” if the engine speed is higher than idle speed. If your foot is not firmly on the brake pedal, the vehicle could accelerate quickly forward or in re- verse. You could lose control of the vehicle and hit someone or something. Only shift into gear when the engine is idling normally and when your right foot is firmly on the brake pedal.

“R” Reverse Use this range only after the vehicle has come to a complete stop.

STARTING AND OPERATING 219

“N” Neutral Shift to Neutral when the vehicle is standing for pro- longed periods with the engine running. The engine may be started in this range. Set the parking brake if you must leave the vehicle. “D” Drive This position provides all forward gears, including 3rd gear direct and 4th gear overdrive (see Overdrive Opera- tion). Use this range for most city and highway driving. “2” Second Use this position for driving slowly in heavy city traffic or on mountain roads where more precise speed control is desirable. Use it also when climbing long grades, and for engine braking when descending moderately steep grades. To prevent excessive engine speed do not exceed 45 mph (72 km/h) in this range.

220 STARTING AND OPERATING

“1” First Use this position for driving up very steep hills and for engine braking at low speeds 20 mph (32 km/h) or less when going downhill. To prevent excessive engine speed, do not exceed 25 mph (40 km/h) in this range. NOTE: Use caution when operating a heavily loaded vehicle in “2” Second or “1” First gear selections in high ambients as torque converter slip can impose significant additional heat load on the cooling system.

WARNING!

Never use Park position on an automatic transmis- sion as a substitute for the parking brake. Always apply parking brake fully when parked to guard against vehicle movement and possible injury or damage.

Overdrive Operation The four-speed overdrive automatic transmission con- tains an electronically controlled fourth speed (Over- drive). The transmission will automatically shift from Drive to Overdrive if the following conditions are present:

† the transmission selector is in Drive;

perature;

† the engine coolant has reached normal operating tem- † vehicle speed is above approximately 30 mph (48
† the “TOW/HAUL” switch has not been activated; † transmission has reached normal operating tempera-

km/h);

ture.

The transmission will downshift from Overdrive to Drive if the accelerator pedal is fully depressed at vehicle speeds above approximately 35 mph (56 km/h). Overdrive can be locked out by pressing the “TOW/ HAUL” button located on the selector lever. The “TOW/ HAUL” light will illuminate in the instrument cluster to indicate that the switch has been activated. Pressing the switch a second time restores the Overdrive function. If the “TOW/HAUL” feature is desired, the“TOW/HAUL” button must be pressed each time the engine is started.

STARTING AND OPERATING 221

If the vehicle is started in extremely cold tem- NOTE: peratures, the transmission may not shift into Overdrive and will automatically select the most desirable gear for operation at this temperature. Normal operation will resume when the transmission fluid temperature has risen to a suitable temperature. Refer also to the Note under torque converter clutch, later in this section. If the transmission temperature gets extremely hot, the transmission will automatically select the most desirable gear for operation at this temperature. If the transmission temperature becomes hot enough the “TOW/HAUL” and/or TRANS TEMP light(s) may illuminate and the transmission may downshift out of Overdrive until the transmission cools down. After cooldown, the transmis- sion will resume normal operation.

occurs, press the “TOW/HAUL” button. This will im- prove performance and reduce the potential for transmis- sion overheating or failure due to excessive shifting. Torque Converter Clutch A feature, designed to improve fuel economy, has been included in the automatic transmission on your vehicle. A clutch within the torque converter engages automati- cally at calibrated speeds. This may result in a slightly different feeling or response during normal operation in high gear. When the vehicle speed drops or during acceleration when the transmission downshifts to second gear, the clutch automatically disengages. NOTE: The torque converter clutch will not engage until the transmission fluid and engine coolant are warm [usually after 1-3 miles (1.6 – 4.8 km) of driving]. Because the engine speed is higher when the torque converter clutch is not engaged, it may seem as if the transmission is not shifting into Overdrive when cold. This is normal.

Pressing the “TOW/HAUL” button, when the transmis- sion is sufficiently warm, will demonstrate that the transmission is able to shift into and out of overdrive. If the vehicle has not been driven in several NOTE: days, the first few seconds of operation after shifting the transmission into gear may seem sluggish. This is due to the fluid partially draining from the torque converter into the transmission. This condition is normal and will not cause damage to the transmission. The torque converter will refill within five seconds of shifting from Park into any other gear position. Manual Transmission – 5–Speed (NV- 4500) — If Equipped

NOTE: The parking brake should be engaged before leaving the vehicle, especially on an incline.

Truck models with manual transmission are equipped with a clutch interlocking ignition system. The clutch pedal must be fully depressed to start the vehicle. Fully depress the clutch pedal before shifting gears. As you release the clutch pedal, lightly depress the accelera- tor pedal. When launching a stationary vehicle, keep the engine speed low until the clutch is fully engaged.

Damage to the clutch can result from starting in 2nd or 3rd gear. Use each gear in numerical order – do not skip a gear.

For improved clutch life, all five forward gears should be used for all load conditions. For steady highway driving with light acceleration, 5th gear is recommended. To shift into 5th gear, move the shift lever to the right beyond the spring pressure point and push it forward. When shifting

STARTING AND OPERATING 223

from 5th to 4th, pull the lever down toward you in one motion. Do not pull the lever sharply left as you may shift accidentally into 2nd gear and damage the trans- mission and engine. To shift into Reverse, come to a complete stop. Depress the clutch and pause briefly to allow the gear train to stop. Move the shift lever from the Neutral position straight across and back into Reverse. Never drive with your foot resting on the clutch pedal, or attempt to hold the vehicle on a hill with the clutch pedal partially engaged, as this will cause abnormal wear on the clutch. Downshifting Moving from a high gear down to a lower gear is recommended to preserve brakes when driving down steep hills. In addition, downshifting at the right time provides better acceleration when you desire to resume speed. Downshifting progressively. Do not skip gears to

224 STARTING AND OPERATING

avoid overspeeding the engine and clutch. For accelera- tion at speeds less than 15 mph (25 km/h), 2nd gear is recommended.

CAUTION!

When descending a hill, be very careful to downshift one gear at a time to prevent overspeeding the engine which can cause valve damage.

Manual Transmission — 6-Speed (NV-5600) — If Equipped

NOTE: The parking brake should be engaged before leaving the vehicle, especially on an incline. Truck models with manual transmission are equipped with a clutch interlocking ignition system. The clutch pedal must be fully depressed to start the vehicle.

Fully depress the clutch pedal before shifting gears. As you release the clutch pedal, lightly depress the accelera- tor pedal. When launching a stationary vehicle, keep the engine speed low until the clutch is fully engaged.

Damage to the clutch can re- sult from starting in 2nd or 3rd gear with a loaded ve- hicle. Use each gear in nu- merical order – do not skip a gear.

This six-speed manual transmission has the same gear ratios for 1st gear and the two highest gears as appear in the five-speed transmission. The advantage is that the middle gears (2nd, 3rd and 4th) have ratios that are closer

together and the overall close ratios enable the driver to optimize available engine power with road speed. For improved clutch life, all six forward gears should be used. For steady highway driving with light acceleration, 6th gear is recommended. When shifting from 4th to 5th gear, apply side effort away and forward without push- ing hard enough to engage Reverse gear. Shifting from 5th to 6th requires the same side effort or the lever will return to center resulting in a shift into 4th gear and damage the transmission, clutch, or engine. You should use low gear when starting from a standing position if under a heavy load. To shift into Reverse, come to a complete stop. Depress the clutch and pause briefly to allow the gear train to stop. Move the shift lever from the Neutral position straight across and up into Reverse.

FOUR-WHEEL- DRIVE OPERATION — IF EQUIPPED † Four-Wheel-Drive Dodge Ram Trucks are equipped with either a Manually Shifted transfer case or an Electronically Shifted transfer case. See the operating instructions for your transfer case, located within this section.

Manually Shifted Transfer Case Operating Information/Precautions The transfer case provides 4 mode positions - 2 (rear)- wheel-drive high range, 4-wheel-drive high range, neu- tral, and 4-wheel-drive low range. This transfer case is intended to be driven in the 2-wheel- drive position (2H) for normal street and highway con- ditions such as dry hard surfaced roads. When additional traction is required the transfer case 4H and 4L positions can be used to lock the front and rear driveshafts together and force the front and rear wheels to rotate at the same speed. This is accomplished by simply moving the shift lever to the desired positions. The 4H and 4L positions are intended for loose, slippery road surfaces only. Driving in the 4H and 4L positions on dry hard surfaced roads may cause increased tire wear and damage to the driveline components.

The 4-wheel-drive light (4WD), located in the instrument cluster, alerts the driver that the vehicle is in 4-wheel drive and that the front and rear driveshafts are locked together. This light illuminates when the transfer case is shifted to either the 4H or 4L positions. There is no light for the 2H or N (Neutral) positions. When operating your vehicle in 4L, the engine speed is approximately three times that of the 2H or 4H positions at a given road speed. Take care not to overspeed 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 will adversely affect shifting and can cause damage to the transfer case.

STARTING AND OPERATING 227

NOTE: Do not attempt to make a shift while only the front or rear wheels are spinning. The 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. 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. NOTE: Delayed shifts out of four-wheel drive may be experienced due to uneven tire wear, low or uneven tire pressures, excessive vehicle loading, or cold tempera- tures.

228 STARTING AND OPERATING

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: 2H Rear Wheel Drive High Range - Normal street and highway driving. Dry hard surfaced roads.

4H 4-Wheel-Drive High Range - Locks the front and rear driveshafts together. Forces the front and rear wheels to rotate at the same speed. Additional traction for loose, slippery road surfaces only. 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. 4L 4-Wheel-Drive Low Range - Low speed 4-wheel-drive. Locks the front and rear driveshafts together. 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).

Shifting Procedure - Manually Shifted Transfer Case

2H , 4H Shifting between 2H and 4H can be made with the vehicle stopped or in motion. If the vehicle is in motion, shifts can be made up to 55 mph (88 km/h). With the

STARTING AND OPERATING 229

vehicle in motion, the transfer case will engage / disen- gage faster if you momentarily release the accelerator pedal after completing the shift. Apply a constant force when shifting the transfer case lever. 2H or 4H , 4L With the vehicle rolling at 2 to 3 mph (3 to 5 km/h), shift an automatic transmission to N (Neutral) or depress the clutch on a manual transmission. While the vehicle is coasting at 2 to 3 mph (3 to 5 km/h), shift the transfer case lever firmly to the desired position. Do not pause in transfer case N (Neutral). NOTE: Pausing in transfer case N (Neutral) in vehicles equipped with an automatic transmission may require shutting the engine OFF to avoid gear clash while completing the shift. If difficulty occurs, shift automatic transmission to N (Neutral), hold foot on brake, and turn engine OFF. Make shift to the desired mode.

230 STARTING AND OPERATING

NOTE: Shifting into or out of 4L is possible with the vehicle completely stopped, however difficulty may oc- cur due to the mating clutch teeth not being properly aligned. Several attempts may be required for clutch teeth alignment and shift completion to occur. The pre- ferred method is with the vehicle rolling 2 to 3 mph (3 to 5 km/h). Avoid attempting to engage or disengage 4L with the vehicle moving faster than 2 to 3 mph (3 to 5
km/h). NOTE: Do not attempt to shift to or from 4L while the transmission is in gear or clutch is engaged. Transfer Case Reminder Light The four-wheel-drive operating light (4WD), located in the instrument cluster, is used to alert the driver that the front axle is fully engaged and all four wheels are driving.

Electronically Shifted Transfer Case Operating Information/Precautions This is an electric shift transfer case and is operated by the 4WD Control Switch (Transfer Case Switch), which is located on the instrument panel. The Electronically Shifted transfer case provides 4 mode positions: 2 (rear) wheel drive high range or all wheel drive high range, 4 wheel drive high range, 4 wheel drive low range, and neutral. The Electronically Shifted transfer case is designed to be driven in the 2 wheel drive position (2WD) or all wheel drive position (AWD) for normal street and highway conditions (dry hard surfaced roads). When additional traction is required, the transfer case 4HI and 4LO positions can be used to lock the front and rear driveshafts together and force the front and rear wheels to rotate at the same speed. This is accomplished by rotating the 4WD Control Switch to the desired

position - see Shifting Procedure section for specific shifting instructions. The 4HI and 4LO positions are designed for loose, slippery road surfaces only. Driving in the 4HI and 4LO positions on dry hard surfaced roads may cause increased tire wear and damage to the driv- eline components. NOTE: The transfer case Neutral (N) position is selected by depressing the recessed button located on the lower left hand corner of the 4WD Control Switch. The transfer case Neutral (N) position is to be used for recreational towing only. See the Recreational Towing section for specific procedures on shifting into and out of Neutral (N). Transfer Case Position Indicator Lights — Electronically Shifted Transfer Case Only Transfer case position indicator lights are located on the Four-Wheel-Drive Control Switch, found on your instru- ment panel, and indicate the current and desired transfer

case selection. When you select a different transfer case position, the indicator lights will do the following: If All Shift Conditions are Met 1. The current position indicator light will turn OFF. 2. The selected position indicator light will flash until the transfer case completes the shift. 3. When the shift is complete, the indicator light for the selected position will stop flashing and remain ON. If One or More Shift Conditions are not Met 1. The indicator light for the current position will remain ON. 2. The newly selected position indicator light will con- tinue to flash. 3. The transfer case will not shift.

232 STARTING AND OPERATING

NOTE: Before retrying a selection, make certain that all the necessary requirements for selecting a new transfer case position have been met. To retry the selection, turn the control knob back to the current position, wait five (5) seconds, and retry selection. To find the shift require- 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 illu- minated. 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 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 2WD/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.

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: 2WD/AWD Rear Wheel Drive High Range - Normal street and highway driving. Dry hard surfaced roads.
