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.
226 UNDERSTANDING YOUR INSTRUMENT PANEL
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.
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.

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 push-button. 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.
238 UNDERSTANDING YOUR INSTRUMENT PANEL
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.
UNDERSTANDING YOUR INSTRUMENT PANEL 239
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.

Damage to the transmission may occur if the follow- ing precautions are not observed: † Shift into PARK only after the vehicle has come to † Shift into or out of REVERSE only after the vehicle has come to a complete stop and the engine is at idle speed. † Do not shift from REVERSE, PARK, or NEUTRAL into any forward gear when the engine is above idle speed. † Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
250 STARTING AND OPERATING
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.
Automatic Transmission with Overdrive 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!
WARNING!
STARTING AND OPERATING 251
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.
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.

ture. 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 level. Refer also to the Note under torque converter clutch, later in this section.
STARTING AND OPERATING 253
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 TRANS TEMP light may illuminate and the transmission may downshift out of Overdrive until the transmission cools down. After cooldown, the transmission will resume normal opera- tion. 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).
254 STARTING AND OPERATING
When To Use “TOW HAUL” and “O/D OFF” Modes
Tow Haul O/D Off Switch
When driving in hilly areas, towing a trailer, carrying a heavy load, etc., and frequent transmission shifting oc- curs, press the “TOW HAUL O/D OFF” button once to select TOW HAUL. This will improve performance and
reduce the potential for transmission overheating or failure due to excessive shifting. When operating in “TOW HAUL” mode, 5th gear (if equipped) is disabled and 2-3 and 3-4 shift patterns are modified. Shifts into Overdrive (4th gear) are allowed during steady cruise (for improved fuel economy) and automatic closed- throttle downshifts to 3rd gear are performed (for im- proved braking) when driving conditions warrant. Press- ing the “TOW HAUL O/D OFF” button a second time to select O/D OFF will disable 4th and 5th gear completely, which should eliminate any excessive transmission shift- ing. The “TOW HAUL” or “O/D OFF” light will illuminate in the instrument cluster to indicate when the switch has been activated. Pressing the switch a third time restores normal operation. If the “TOW HAUL” or “O/D OFF” modes are desired, the button must be pressed each time the engine is started.
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 the upper gears. 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 O/D OFF” button, when the transmission is sufficiently warm, will demonstrate that the transmission is able to shift into and out of overdrive.
STARTING AND OPERATING 255
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
WARNING!
You or others could be injured if you leave the vehicle unattended without having the parking brake fully applied. The parking brake should al- ways be applied when the driver is not in the vehicle, especially on an incline.
256 STARTING AND OPERATING
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. 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.
Manual Transmission — 6 Speed (G56)
The Power Wagon may be equipped with the G56
manual transmission. This transmission has a “creeper”
1st gear which should be used to start from a standing
position when carrying a payload or towing a trailer.
Damage to the clutch can result from starting in 2nd or
3rd gear with a loaded vehicle. An unloaded vehicle may
be launched in 2nd gear. Use each gear in numerical
order – do not skip a gear.
For most city driving you may find it easier to use only
1st through 5th gear ranges. For steady highway driving
with light accelerations, 6th 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 from 5th to 4th gear, 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 transmission.
To shift into Reverse, come to a complete stop. Depress the clutch and pause briefly to allow the gear train to stop. Reverse has a “crash-through” lockout feature. Move the shift lever from the Neutral position straight across, in one swift motion, and down into Reverse. Recommended Vehicle Shift Speeds To utilize your manual transmission efficiently for both fuel economy and performance, it should be upshifted as listed in recommended shift speed chart. Shift at the vehicle speeds listed for acceleration. Earlier upshifts during cruise conditions (steady speeds) will result in increased fuel economy, and may be used as indicated. 6 Speed Manual Transmission Shift Speeds in mph

STARTING AND OPERATING 257
Downshifting – All Manual Transmissions
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. For acceleration at speeds less than 20 mph (30
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.

FOUR-WHEEL- DRIVE OPERATION
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 high (4LOCK) and 4–wheel drive low (4LOW) lights, located in the instrument cluster, alert the driver that the vehicle is either in 4-wheel drive high or 4–wheel drive low and that the front and rear driveshafts are locked together. There are no lights 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 259
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.
260 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
Manual Transfer Case Shifter
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 261
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.
262 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 (4LOCK), located in
the instrument cluster, is used to alert the driver that the
front axle is fully engaged and all four wheels are
driving.
LIMITED-SLIP DIFFERENTIAL — IF EQUIPPED The limited-slip differential provides additional traction on snow, ice, mud, sand and gravel, particularly when there is a difference between the traction characteristics of the surface under the right and left rear wheels. During normal driving and cornering, the limited-slip unit per- forms similarly to a conventional differential. On slip- pery surfaces, however, the differential delivers more of the driving effort to the rear wheel having the better traction. The limited-slip differential is especially helpful during slippery driving conditions. With both rear wheels on a slippery surface, a slight application of the accelerator will supply maximum traction. When starting with only one rear wheel on an excessively slippery surface, slight momentary application of the parking brake may be necessary to gain maximum traction.
WARNING!
On vehicles equipped with a limited-slip differen- tial, never run the engine with one rear wheel off the ground, since the vehicle may drive through the rear wheel remaining on the ground. You could 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.
STARTING AND OPERATING 263
DRIVING ON SLIPPERY SURFACES 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.
264 STARTING AND OPERATING
Axle Locker System Dodge Power Wagons are equipped with electronically locking front and rear axles. Locking the axles provides greater traction in severe low traction conditions or in rock climbing environments where one wheel is likely to not be in contact with the ground.
CAUTION!
Do not lock the front or rear axle on hard surfaced roads. The ability to steer the vehicle is reduced and damage to the drivetrain may occur when the axles are locked on hard surfaced roads.
CAUTION!
Do not try to lock the rear axle if the vehicle is stuck and the tires are spinning. You can damage driv- etrain components. Lock the rear axle before at- tempting situations or navigating terrain, which could possibly cause the vehicle to become stuck.
The locking axles are controlled by the axle locker switch located on the center console.
STARTING AND OPERATING 265
rear axles are unlocked. In the REAR LOCK position, the rear axle is locked. In the FRONT/REAR position, the front and rear axles are locked. NOTE: Even when the axles are in the AXLE UNLOCK position, the limited slip differential in the rear axle still provides torque biasing capability for moderate low traction environments. During the command to lock the axle, the indicator light will flash until the axle is locked. After the lock command has been successfully executed, the light will remain on solid. To lock the rear axle, place the vehicle in 4LO by following the procedure in Four Wheel Drive Operation, located in this section of the manual. Move the axle locker switch position to REAR LOCK while traveling less than 3 MPH (5 KM/H). The RR indicator light will remain on when the rear axle is locked.
Rotary Locking Axle Switch
The switch has three positions, AXLE UNLOCK, REAR LOCK, and FRONT/REAR. Under normal driving con- ditions the switch should be left in the AXLE UNLOCK position. In the AXLE UNLOCK position, the front and
266 STARTING AND OPERATING
NOTE: Left to right wheel speed difference may be necessary to allow the axle to fully lock. If the indicator light is flashing after placing the switch in the REAR LOCK or FRONT/REAR position, drive the vehicle in a turn or on loose gravel to expedite the locking action.
WARNING!
Do not use the locked axle position for normal driving. A locked front axle is intended for off-road driving only. Locking the front axle during on-road driving will reduce the steering ability. This could cause an accident and you may be seriously injured.
To lock the front axle move the axle locker switch to
FRONT/REAR while traveling less than 3 MPH (5
KM/H). The indicator light will be solid when the front
axle is locked.
NOTE: The rear axle must be locked before the front axle will lock. To unlock the front axle move the axle locker switch to REAR LOCK. The FRONT/REAR indicator light will go out when the axle is unlocked. NOTE: The axle lockers could be torque locked due to side to side loads on the axle. Driving slowly while turning the steering wheel from a left hand turn to a right hand turn or driving in reverse for a short distance may be required to release the torque lock and unlock the axles. To unlock the rear axle move the axle locker switch to AXLE UNLOCK. The REAR LOCK indicator light will go out when the rear axle is unlocked.
Stabilizer/Sway Bar System Power Wagon vehicles are equipped with an electronic disconnecting stabilizer/sway bar. This system allows greater front suspension travel in off-road situations. This system is controlled by the electronic control sway bar switch located on the instrument panel.
Electronic Control Sway Bar Switch
STARTING AND OPERATING 267
The switch has two positions, on-road and off-road. The system is normally in on-road mode, indicated by a solid green light. The stabilizer/sway bar should remain in on-road mode during normal driving conditions.
WARNING!
Do not disconnect the stabilizer bar and drive on hard surfaced roads or at speeds above 18 MPH, you may lose control of the vehicle, which could result in serious injury. The front stabilizer bar enhances vehicle stability and is necessary for maintaining control of the vehicle. The system monitors vehicle speed and will attempt to reconnect the stabilizer bar at speeds over 18 MPH. This is indicated by a flashing off road light and solid on road light. Once vehicle speed is reduced below 14 MPH the system will once again attempt to return to off road mode.
268 STARTING AND OPERATING
To disconnect the stabilizer/sway bar, shift to either 4HI or 4LO as shown in Four Wheel Drive Operation and press the top of the stabilizer/sway bar button to obtain the off-road position. The amber indicator light will flash until the stabilizer/sway bar has been fully disconnected. NOTE: The stabilizer/sway bar may be torque locked due to left and right suspension height differences. This condition is due to driving surface differences or vehicle loading. to disconnect/reconnect, the right and left halves of the bar must be aligned. This alignment may require that the vehicle be driven onto level ground or rocked from side to side. To return to on-road mode press the bottom of the stabilizer/sway bar button.

POWER WAGON – SAFE OFF-ROAD DRIVING
Off-Road Driving Tips and Vehicle Characteristics The Power Wagon has excellent on and off-road capabili- ties. These off-road capabilities will allow you to explore those wilderness trails where few travel, providing a source of exciting and satisfying recreation. Before you venture out you should contact your local governmental agency to determine what are the designated off-road

High Mobility Characteristics The Power Wagon has high off-road mobility character- istics with an approach angle A= 35 degrees, a break-over angle B= 25.5 degrees, a running ground clearance C= 14.5 inches, a departure angle D= 26.5 degrees, an axle to ground clearance E= 8.4 inches front/E= 8.25 rear and has a ramp travel index (with the smart bar in off-road mode) of 655. Also the Power Wagon has a grade-ability of a 60% (31 degree) slope.
vehicle (ORV) trails or recreation areas. You should always tread lightly and only use established roads, trails or ORV recreational areas. The National Forest Service, Bureau of Land Management or local Department of Natural Resources are a wealth of information and usu- ally have maps with marked trails. Ramp Travel Index (RTI) The ramp travel index is the distance, in inches, that you can drive your vehicle with one wheel on a 20-degree ramp without lifting any other wheel off the ground. This distance up the ramp divided by the wheelbase of the vehicle and multiplied by 1000 is the RTI. The Power Wagon has an RTI of 655, which means you can articulate one front wheel 32 inches in the air while the other three wheels remain in contact with the ground.

CAUTION!
The door sill height is 25 inches. Water may intrude into the interior of the vehicle at greater depths.
Simultaneous Brake And Throttle Operation Many off-road driving conditions require the simulta- neous use of the brake and throttle (two footed driving). When climbing rocks, logs, or other stepped objects, using light brake pressure with light throttle will keep the vehicle from jerking or lurching. This technique is also used when you need to stop and restart a vehicle on a steep incline.
The Basics Of Off-Road Driving You will encounter many types of terrain driving off- road. You should be familiar with the terrain and area before proceeding. There are many types of surface conditions: hard packed dirt, gravel, rocks, grass, sand, mud, snow and ice. Every surface has a different effect on your vehicle’s steering, handling and traction. Control- ling your vehicle is one of the keys to successful off-road driving, so always keep a firm grip on the steering wheel and maintain a good driving posture. Avoid sudden accelerations, turns or braking. In most cases there are no road signs, posted speed limits or signal lights. Therefore you will need to use your own good judgment on what is safe and what isn’t. When on a trail you should always be looking ahead for surface obstacles and changes in terrain. The key is to plan your future driving route while remembering what you are currently driving over.
CAUTION!
Never park your vehicle over dry grass or other combustible materials. The heat from your vehicle exhaust system could cause a fire.
WARNING!
Always wear your seat belt and firmly tie down cargo. Unsecured cargo can become projectiles in an off-road situation.
When To Use Low Range When driving off-road, shift into 4L (Low range) for additional traction or to improve handling and control on slippery or difficult terrain. Due to the lower gearing, low range will allow the engine to operate in a higher power range. This will allow you to idle over obstacles and
STARTING AND OPERATING 273
down hills, with improved control and less effort. Also, use 4L (Low range) in rain, ice, snow, mud, sand, to get heavy loads rolling, improve traction, or whenever 4H (High range) traction will not do the job. Driving in Snow, Mud and Sand There is a drastic reduction in traction when driving in snow, mud or sand. The vehicle will be less responsive to steering, acceleration and braking inputs. Therefore you should accelerate slowly, leave greater stopping distances and avoid abrupt vehicle maneuvers. You want to keep a slow constant steady pace. The key is to maintain the vehicle’s momentum. † Snow – In heavy snow or for additional control and traction at slower speeds, shift the transmission to a low gear and shift the transfer case to 4L (Low) if necessary. Don’t shift to a lower gear than necessary to maintain headway. Over-revving the engine can spin the wheels and traction will be lost. If you start to slow
274 STARTING AND OPERATING
to a stop, try turning your steering wheel no more than
a 1⁄4 turn quickly back and forth, while still applying
throttle. This will allow the tires to get a fresh 9bite9
and help maintain your momentum.
CAUTION!
On icy or slippery roads, do not downshift at high engine rpm’s or vehicle speeds because engine brak- ing may cause skidding and loss of control. † Mud – Deep mud creates a great deal of suction around the tires and is very difficult to get through. You should use 4L (low range) with a gear low enough to maintain your momentum without shifting. If you start to slow to a stop, try turning your steering wheel no more than a 1⁄4 turn quickly back and forth for additional traction. Mud holes pose an increased threat of vehicle damage and getting stuck. They are
normally full of debris from previous vehicles getting stuck. As a good practice before entering any mud hole, get out and determine how deep it is, if there are any hidden obstacles and if the vehicle can be safely recovered if stuck. † Sand – Soft sand is very difficult to travel through with full tire pressure. When crossing soft sandy spots in a trail maintain your vehicle’s momentum and do not stop. The key to driving in soft sand is to use the appropriate tire pressure, accelerating slowly, avoid- ing abrupt maneuvers and maintaining the vehicle’s momentum. If you are going to be driving on large soft sandy areas or dunes, reduce your tire pressure to a minimum of 15 psi (103 kPa) to allow for a greater tire surface area. Reduced tire pressure will drastically improve your traction and handling, while driving on the soft sand, but you must return the tires to normal
air pressure before driving on pavement or other hard surfaces. Be sure you have a way to air the tires back up prior to reducing the pressure.
CAUTION!
Reduced tire pressures may cause tire unseating and total loss of air pressure. To reduce the risk of tire unseating, while at a reduced tire pressure, reduce your speed and avoid sharp turns or abrupt maneu- vers.
Crossing Obstacles (Rocks And Other High Points) While driving off road, you will encounter many types of terrain. These varying types of terrain bring different types of obstacles. Before proceeding review the path ahead to determine the correct approach and your ability to safely recover the vehicle if something goes wrong.
STARTING AND OPERATING 275
Keeping a firm grip on the steering wheel, bring the vehicle to a complete stop and then inch the vehicle forward until it makes contact with the object. Apply the throttle lightly while holding a light brake pressure and ease the vehicle up and over the object.
WARNING!
Crossing obstacles can cause abrupt steering system loading which could cause you to loose control of your vehicle.
Using A Spotter There are many times where it is hard to see the obstacle or determine the correct path. Determining the correct path can be extremely difficult when you are confronting many obstacles. In these cases have someone guide you over, through, or around the obstacle. Have the person
276 STARTING AND OPERATING
stand a safe distance in front of you where they can see the obstacle, watch your tires and undercarriage, and guide you through. Crossing Large Rocks When approaching large rocks, choose a path which ensures you drive over the largest of them with your tires. This will lift your undercarriage over the obstacle. The tread of the tire is tougher and thicker than the side wall and is designed to take the abuse. Always look ahead and make every effort to cross the large rocks with your tires.
CAUTION!
Never attempt to straddle a rock that is large enough to strike your axles or undercarriage.
CAUTION!
Never attempt to drive over a rock which is large enough to contact the door sills.
Crossing A Ravine, Gully, Ditch, Washout Or Rut When crossing a ravine, gully, ditch, washout or a large rut, the angled approach is the key to maintaining your vehicle’s mobility. Approach these obstacles at a 45- degree angle and let each tire go through the obstacle independently. You need to use caution when crossing large obstacles with steep sides. Do not attempt to cross any large obstacle with steep sides at an angle great enough to put the vehicle at risk of a roll over. If you get caught in a rut, dig a small trench to the right or left at a 45-degree angle ahead of the front tires. Use the removed dirt to fill the rut ahead of the turnout you just created. You should now be able to drive out following the trench you just created at a 45-degree angle.
WARNING!
CAUTION!
STARTING AND OPERATING 277
There is an increased risk of roll over when crossing an obstacle, at any angle, with steep sides.
Crossing Logs To cross a log, approach it at a slight angle (approxi- mately 10 to 15 degrees). This allows one front tire to be on top of the log while the other just starts to climb the log. While climbing the log, modulate your brake and accelerator to avoid spinning the log out from under your tires. Then ease the vehicle off the log using your brakes.
Do not attempted to cross a log with a greater diameter than the running ground clearance or the vehicle will become high centered.
Getting High Centered If you get hung up or high centered on an object, get out of the vehicle and try to determine what the vehicle is hung up on, where it is contacting the underbody and what is the best direction to recover the vehicle. Depend- ing on what you are in contact with, jack the vehicle up and place a few rocks under the tires so the weight is off of the high point when you let the vehicle down. You can also try rocking the vehicle or winching the vehicle off the object.
278 STARTING AND OPERATING
CAUTION!
Winching or rocking the vehicle off hard objects increases the risk of underbody damage.
Hill Climbing Hill climbing requires good judgment and a good under- standing of your abilities and your vehicle’s limitations. Hills can cause serious problems. Some are just too steep to climb and should not be attempted. You should always feel confident with the vehicle and your abilities. You should always climb hills straight up and down. Never attempt to climb a hill on an angle. † Before Climbing A Steep Hill – As you approach a hill consider its grade or steepness. Determine if it is too steep. Look to see what the traction is on the hill side trail. Is the trail straight up and down? What is on top and the other side? Are there ruts, rocks, branches
or other obstacles on the path? Can you safely recover the vehicle if something goes wrong? If everything looks good and you feel confident, then change trans- mission into a lower gear, shift the transfer case into 4L (Low) and proceed with caution. You should use first gear and 4L (Low) for very steep hills. † Driving Up Hill – Once you have determined your ability to proceed and have shifted into the appropri- ate gear, line your vehicle up for the straightest possible run. Accelerate with an easy constant throttle and apply more power as you start up the hill. Do not race forward into a steep grade, the abrupt change of grade could cause you to lose control. If the front end begins to bounce, ease off the throttle slightly to bring all four tires back on the ground. As you approach the crest of the hill ease off the throttle and slowly proceed over the top. If the wheels start to slip as you approach the crest of a hill, ease off the accelerator and maintain headway by turning the steering wheel no more than
a 1⁄4 turn quickly back and forth. This will provide a fresh 9bite9 into the surface and will usually provide enough traction to complete the climb. If you do not make it to the top, place the vehicle in reverse and back straight down the grade using engine resistance along with the vehicle brakes.
WARNING!
Never attempt to climb a hill at an angle or turn around on a steep grade. Driving across an incline increases the risk of a roll over, which may result in severe injury. † Driving Down Hill – Before driving down a steep hill you need to determine if it is too steep for a safe descent. What is the surface traction? Is the grade too steep to maintain a slow controlled descent? Are there obstacles? Is it a straight descent? Is there plenty of
STARTING AND OPERATING 279
distance at the base of the hill to regain control if the vehicle descends to fast? If you feel confident in your ability to proceed then make sure you are in 4L (Low) with the transmission in 1st gear (manually select 1st gear on automatic transmissions) and proceed with caution. Allow engine braking to control the descent and apply your brakes if necessary, but do not allow the tires to lock.
WARNING!
Do not descend a steep grade in neutral. Use vehicle brakes in conjunction with engine braking. De- scending a grade too fast could cause you to lose control and be seriously injured. † Driving Across An Incline – If at all possible avoid driving across an incline. If it is necessary, know your vehicle’s abilities. Driving across an incline places
280 STARTING AND OPERATING
more weight on the down hill wheels, which increases the possibilities of a down hill slide or roll over. Make sure the surface has good traction with firm and stable soils. If possible transverse the incline at an angle heading slightly up or down.
WARNING!
Driving across an incline increases the risk of a roll over, which may result in severe injury. † If You Stall Or Begin To Lose Headway – If you stall or begin to lose headway while climbing a steep hill, allow your vehicle to come to a stop and immediately apply the brake. Restart the engine and shift to R (Reverse). Back slowly down the hill allowing the compression braking of the engine and transmission to
help regulate your speed. If the brakes are required to control vehicle speed, apply them lightly and avoid locking or skidding the tires.
WARNING!
If the engine stalls or you lose headway or cannot make it to the top of a steep hill or grade, never attempt to turn around. To do so may result in tipping and rolling the vehicle, which may result in severe injury. Always back carefully straight down a hill in R (Reverse) gear. Never back down a hill in N (Neutral) or with the clutch pedal depressed using only the vehicle brakes. Never drive diagonally across a hill, always drive straight up or down.
Driving Through Water Extreme care should be taken crossing any type of water. Water crossings should be avoided if possible and only be attempted when necessary, in a safe responsible manner. You should only drive through areas which are desig- nated and approved. You should tread lightly and avoid damage to the environment. You should know your vehicles abilities and be able to recover it if something goes wrong. You should never stop or shut a vehicle off when crossing deep water unless you ingested water into the engine air intake. If the engine stalls do not attempt to restart it. Determine if it has ingested water first. The key to any crossing is low and slow. You want to use 1st gear in 4L (low) and proceed very slowly with a constant slow speed (3-5 mph maximum) and light throttle. Keep the vehicle moving; do not try to accelerate through the crossing. After crossing any water higher than the bottom of the axle differentials, you should inspect all of the vehicle fluids for signs of water ingestion.
STARTING AND OPERATING 281
CAUTION!
Water ingestion into the axles, transmission, transfer case, engine or vehicle interior can occur if you drive too fast or through too deep of water. Water can cause permanent damage to engine, driveline or other vehicle components and your brakes will be less effective once wet and/or muddy † Before You Cross Any Type Of Water – As you approach any type of water you need to determine if you can cross it safely and responsibly. If necessary, get out and walk through the water or probe it with a stick. You need to be sure of its depth, approach angle, current and bottom condition. Be careful of murky or muddy waters, check for hidden obstacles. Make sure you will not be intruding on any wildlife and you can recover the vehicle if necessary. The key to a safe
282 STARTING AND OPERATING
crossing is the water depth, current and bottom con- ditions. On soft bottoms the vehicle will sink in, effectively increasing the water level on the vehicle. Be sure to consider this when determining the depth and the ability to safely cross. † Crossing Puddles, Pools, Flooded Areas Or Other Standing Water – Puddles, pools, flooded or other standing water areas normally contain murky or muddy waters. These water types normally contain hidden obstacles and make it difficult to determine an accurate water depth, approach angle, and bottom condition. Murky or muddy water holes are where you want to hook up tow straps prior to entering. This makes for a faster, cleaner and easier vehicle recovery. If you are able to determine you can safely cross, than proceed using the low and slow method.
CAUTION!
Muddy waters can reduce the cooling system effec- tiveness by depositing debris onto the radiator. † Crossing Ditches, Streams, Shallow Rivers Or Other Flowing Water – Flowing water can be extremely dangerous. Never attempt to cross a fast running stream or river even in shallow water. Fast moving water can easily push your vehicle downstream sweeping it out of control. Even in very shallow water, a high current can still wash the dirt out from around your tires putting you and your vehicle in jeopardy. There is still a high risk of personal injury and vehicle damage with slower water currents in depths greater than the vehicle’s running ground clearance. You should never attempt to cross flowing water which is deeper than the vehicle’s running ground clearance. Even the slowest current can push the heaviest vehicle
downstream out of control if the water is deep enough to push on the large surface area of the vehicle’s body. Before you proceed determine the speed of the current, the water’s depth, approach angle, bottom condition and if there are any obstacles, then cross at an angle heading slightly upstream using the low and slow technique.
WARNING!
Never drive through fast moving deep water. It can push your vehicle downstream, sweeping it out of control. This could put you and your passengers at risk of injury or drowning.
STARTING AND OPERATING 283
Airing Down For Off-Road Driving Running lower tire pressure off-road can improve your ride comfort and vehicle traction. Reducing the tire air pressure allows the tire to bulge slightly, improving its surface area for better flotation and ability to mold or form to the ground contour. Different terrain, tires, and vehicles require different tire pressure. Hard surfaces like rock and heavier vehicles require higher pressures than softer surfaces such as sand and lighter vehicles. You will need to experiment to determine what is right for your situation. It is easier and faster to let air out than it is to replace it so, start high and lower it as required. Remem- ber you must return the tires to normal air pressure before driving on road or at highway conditions. Be sure you have a way to return the tires to their normal on road air pressure.
284 STARTING AND OPERATING
CAUTION!
Reduced tire pressure increases the risk of tire dam- age and may cause tire unseating with total loss of air pressure. To reduce the risk of tire unseating, while at a reduced tire pressure, drive at slower speeds and avoid sharp turns or abrupt maneuvers.
Vehicle Recovery If you drive off-road, you may encounter a situation where you will need to recover your vehicle. Vehicle recovery should always be given consideration before attempting a questionable obstacle. You should never go off-road driving without the ability to recover your vehicle from a situation. Having another vehicle with you usually works best for most situations. The first thing to do is assess the situation. Why are you stuck? Are you hung up on something? Would it be easier to go forward or to go backward? Can you still move the
vehicle? Is there an anchor point to winch to? Are you alone or do you have another vehicle to help? Is there high risk of vehicle damage during the recovery process? Answering these questions will help you determine the best method of recovery. If you can still move the vehicle slightly and the only issue is slick ground, then rock cycling your vehicle would be the first choice. If you have ample room, an additional vehicle and there is low risk of vehicle impingement on the surroundings, then using a tow strap to the vehicle tow hooks would be fast and easy. If the vehicle is severely hung up or in a situation where great care needs to be taken during the recovery, then nothing can do the job better than a winch. If you are severely hung up on something you should jack the vehicle up and stack something under the wheels to allow the vehicle to roll off the object without causing further damage. This should be tried before attempting any recovery method.
CAUTION!
Pulling the vehicle off an obstacle, without first clearing the object, may result in additional under- body damage. † Rock Cycling Your Vehicle – Rock cycling your ve- hicle is one of the easiest, fastest and most commonly used methods. This simply involves shifting your vehicle from drive to reverse, while applying throttle after each shift. During this process, for additional traction, try turning your steering wheel quickly back and forth no more than a 1⁄4 turn. If you are stuck in mud, sand, or snow try spinning your tires during this process to clean the debris from the tread and improve the traction. You want to create a rocking motion with the vehicle. This helps build vehicle momentum, which hopefully gets you out. Remember to ease off and on the accelerator before and after the shift. If after
STARTING AND OPERATING 285
a few rock cycles your vehicle is not free, stop and try another method of recovery. Continuous rock cycling will only cause unnecessary damage to your vehicle and the environment.
CAUTION!
Damage can occur when spinning your tires at an excessive high speed. Do not spin your tires faster than an indicated 35 mph † Using The Tow Hooks With A Tow Strap – Tow straps are a quick and easy way to recover your vehicle from minor situations if you have a secondary vehicle which is not stuck. The tow hooks on your vehicle are designed to take the abusive force gener- ated during vehicle recovery. Do not use the bumper or any other vehicle component as an attachment point. Using tow straps requires coordination between
286 STARTING AND OPERATING
the two drivers. Good communication and line of sight are required for a safe recovery. First connect the tow strap to the correct attachment points on both vehicles. There should be a least 20 to 30 feet between the vehicles to allow for a safe recovery. If necessary join two tow straps together using a 1 1⁄2 inch hard wood dowel. This will keep the straps from becoming knot- ted and is safer than using a clevis pin if the strap breaks. Next have the tow vehicle backup, leaving 2 to 3 feet worth of slack in the strap. Then the tow vehicle, using light throttle, should accelerate tightening the strap providing the pulling force needed to free the vehicle. The vehicle being recovered should assist in the recovery, at the time of the snap, by slowly spinning the tires in the same direction as the pulling vehicle. After the vehicle becomes free, the driver of the previously stuck vehicle should signal they are free and should hit their brakes stopping both vehicles. The driver of the pulling vehicle should let off the
throttle without using the brakes, once signaled by the other driver. This sequence is important to avoid having the recovered vehicle hit the pulling vehicle.
WARNING!
Never use tow straps with end hooks or link two straps with a clevis pin. These heavy metal objects could become projectiles if a strap breaks, which could cause severe injury. Never leave more than 2 or 3 feet of slack in the strap. More slack than this greatly increases the risk of injury and vehicle dam- age. Always keep everyone at least 30 feet away from a strapping or winching situation. † Winching (see the section on “Winch Operation” for additional information on the Power Wagon’s winch) – Winching is most commonly used in the following situations: there is no support vehicle available, a high
STARTING AND OPERATING 287
left on the drum, and place a floor mat or something else over the strung out cable. Placing something over the strung out cable helps keep the cable on the ground if it breaks. Next, place the vehicle in 1st gear and apply a very light throttle as you power the winch in. Be careful not to allow slack in the cable as you recover the vehicle. Do not try to guide the cable into the drum. If it starts to bunch up on one end, let it. You can re-spool the cable afterwards. Never use a winch cable as a tow strap and always stand back while winching.
controlled force is required to recover the vehicle, there is a high risk of environmental or vehicle dam- age, or where nothing else seemed to work. A winch can deliver a high pulling force with a great deal of control. It allows you to walk the vehicle out of the situation in a slow controlled manor. This control works well for avoiding further vehicle damage. Once you decide it is time to use the winch look for a good anchor point. It needs to be strong enough to hold more than the vehicle’s weight and provide a direction of pull as straight as possible. Use block and tackle if necessary to improve the angle of pull or increase the winch’s pulling force. If the anchor point is a tree use a strap around its base and hook the cable to the strap. If it is another vehicle, then place that vehicle in park and block the front tires. If you cannot find an anchor point within reach try using your spare tire by burying it. Once you have determined an anchor point hook up the cable, ensuring there are a least five wraps of cable
288 STARTING AND OPERATING
WARNING!
Winch cables are under high tension when in use and can become a projectile if they fail. Never stand over or straddle the winch cable. Never jerk or overload the winch cable. Never stand in front of the vehicle while winching. Failure to follow these in- structions can result in serious or fatal injury.
After Driving Off-Road Off-road operation puts more stress on your vehicle than does most on-road driving. After driving off-road, it is always a good idea to check for damage. † Completely inspect the underbody of your vehicle. Check tires, body structure, steering, suspension, and exhaust system for damage.
† Check threaded fasteners for looseness, particularly on the chassis, drivetrain components, steering, and sus- pension. Retighten them, if required, and torque to the values specified in the Service Manual. † Check for accumulations of plants or brush. These things could be a fire hazard, or they might hide damage to fuel lines, brake hoses, axle pinion seals, and propeller shafts. † After extended operation in mud, sand, water, or similar dirty conditions, have brake drums and rotors, brake linings, and axle yokes inspected and cleaned as soon as possible. † If you experience unusual vibration after driving in mud, slush or similar conditions, check the wheels for packed material. Packed foreign material can cause a wheel imbalance and cleaning the wheels will correct the situation.
WARNING!
Abrasive material in any part of the brakes may cause excessive wear or unpredictable braking. You might not have full braking power when you need it to prevent an accident. If you have been operating your vehicle in dirty conditions, get your brakes checked and cleaned as necessary. Failure to do so may result is serious injury.
WINCH USAGE – IF EQUIPPED
Things To Know Before Using Your Winch
General Winch Information Your vehicle is equipped with an electric vehicle recovery winch. This winch uses the electrical power from the vehicle charging system to power a motor that winds wire rope into the winch drum via planetary gear reduc- tion. By nature, a winch is capable of generating very
STARTING AND OPERATING 289
high forces and should be used with care. Do not operate the winch without reading and understanding the com- plete winch owner’s manual. Tensioning the Wire Rope The winch rope must be properly tensioned before use. Follow the instructions below to tension the rope: 1. Un-spool the wire rope leaving 5 wraps of rope on the winch drum. 2. Attach the hook to a suitable anchor point.
CAUTION!
Be certain the anchor will withstand the load re- quired to tension the wire rope.
290 STARTING AND OPERATING
3. Apply at least 500 lbs. of tension to the rope while winding the rope in. Always use care to ensure the rope does not pile up on one side of the drum and is neatly wound onto the drum.
CAUTION!
Wire rope must spool on the winch drum in the direction indicated on the drum rotation decal on the winch.
Low Voltage Interrupt Your winch is equipped with a device that will interrupt winch function if the vehicle charging system voltage
drops to a low level. The winch will not power-in or out for 30 seconds if this device is tripped. If the interrupt is tripped, the vehicle should be operated at high idle for a few minutes to allow the vehicle charging system to recover before continuing to winch. Winch Motor Thermal Protection Your winch is equipped with a thermal protection device in the motor. If the winch is operated for an excessive duration, the device may interrupt motor function to protect the winch motor. During this time the winch will power-out but will not power-in. Allow the winch motor to cool for a few minutes before continuing to winch. The winch will resume normal function once the motor cools.

Winch Components
292 STARTING AND OPERATING
1. Motor: The winch motor is powered by the vehicle charging system and features a thermal protection switch that automatically stops motor function in the power-in direction if the motor gets too hot. 2. Remote Socket: The remote socket allows the remote control to be attached to the control pack to allow the winch to function. 3. Winch Drum w/ Integral Brake: The winch drum allows the wire rope to be stored on the winch and transmits force to the wire rope. The winch is equipped with an integral brake that will stop rotation of the winch drum if the winch motor is stopped. 4. 3 Stage Planetary Gear Set: Provides balance between speed and pulling power. 5. Wire Rope: The wire rope allows the winch to be connected to an anchor to provide a pulling force.
6. Clutch Lever: The clutch lever allows the winch drum to be disconnected from the winch motor to allow the wire rope to be pulled from the winch by hand. 7. Remote Control: The remote control provides the interface between the winch operator and the winch. The remote control provides the ability to power the winch in, out, and stop the winch. To operate the winch, the toggle switch is pressed down to power the winch in and up to power the winch out. The winch will stop if the switch is left in the neutral (center) position.
CAUTION!
If not installed, the hook strap must be placed on the hook.
Fairlead: The fairlead acts as a guide for the wire rope and minimizes damage to the rope.
WINCH ACCESSORIES
The following accessories are necessary to attach the winch to anchors, change direction of pull, and for safe winching.
