Notes On Playing MP3 Files The radio can play MP3 files; however, acceptable MP3
file recording media and formats are limited. When writing MP3 files, pay attention to the following restric- tions. Supported Media (Disc Types) The MP3 file recording media supported by the radio are CD-ROM, CD-R, and CD-RW. Supported Medium Formats (File Systems) The medium formats supported by the radio are ISO 9660
Level 1 and Level 2 and includes the Joliet extension. When reading discs recorded using formats other than ISO 9660 Level 1 and Level 2, the radio may fail to read files properly and may be unable to play the file nor- mally. UDF and Apple HFS formats are not supported.UNDERSTANDING YOUR INSTRUMENT PANEL 243
The radio uses the following limits for file systems: † Maximum number of directory levels: 15
† Maximum number of files: 255
† Maximum number of folders: 100
† Maximum number of characters in file/folder names: † Level 1: 12 (including a separator 9.9 and a † Level 2: 31 (including a separator3-character extension)
9.9 and a
3-character extension)
Multisession disc formats are supported by the radio. Multisession discs may contain combinations of normal CD audio tracks and computer files (including MP3 files). Discs created with an option such as 9keep disc open after writing9 are most likely multisession discs. The use of multisession for CD audio or MP3 playback may result in longer disc loading times.
244 UNDERSTANDING YOUR INSTRUMENT PANEL
Supported MP3 File Formats The radio will recognize only files with the *.mp3 exten- sion as MP3 files. Non-MP3 files named with the *.mp3
extension may cause playback problems. The radio is designed to recognize the file as an invalid MP3 and will not play the file. When using the MP3 encoder to compress audio data to an MP3 file, the bit rate and sampling frequencies in the following table are supported. In addition, variable bit rates (VBR) are also supported. The majority of MP3 files use a 44.1 kHz sampling rate and a 192, 160, 128, 96 or VBR bit rates.MPEG Specifi-

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. 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 direction.
UNDERSTANDING YOUR INSTRUMENT PANEL 257
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.
258 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.

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. For proper coolant type, refer to “Recommended Fluids and Genuine Parts” in Section 7. 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.
270 UNDERSTANDING YOUR INSTRUMENT PANEL
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.

STARTING PROCEDURES – GAS ENGINES Before starting your vehicle, adjust your seat, adjust both inside and outside mirrors, and fasten your seat belts. The starter should not be operated for more than 15- second intervals. Waiting a few seconds between such intervals will protect the starter from overheating.
WARNING!
Be sure to turn off the engine and remove the key from the ignition switch if you want to rest or sleep in your vehicle. Accidents can be caused by inadvert- ently moving the gear selection lever or by pressing the accelerator pedal. This may cause excessive heat in the exhaust system, resulting in overheating and vehicle fire which may cause serious or fatal injuries.
WARNING!
Do not leave children or animals inside parked vehicles in hot weather. Interior heat buildup may cause serious injury or death.
Normal Starting Normal starting of either a warm or cold engine is obtained without pumping or depressing the accelerator pedal. Turn the key to the START position and release when the engine starts. If the engine fails to start within 10 seconds, turn the key to the OFF position, wait five seconds, then repeat the starting procedure.
Automatic Transmission – If Equipped Start the engine with the shift lever in the NEUTRAL or PARK position. Apply the brake before shifting to any driving range. NOTE: This vehicle is equipped with a transmission shift interlocking system. The brake pedal must be depressed to shift out of PARK.
Tip Start Feature – Automatic Transmission Only Do not press the accelerator. Turn the ignition key briefly to START position, and release it. The starter motor will continue to run, but will automatically disengage when the engine is running.
STARTING AND OPERATING 279
Ignition Key Positions Manual Transmission – If Equipped Apply the parking brake, place the shift lever in NEU- TRAL and depress the clutch pedal to the floor before starting the vehicle. This vehicle is equipped with a clutch interlocking ignition system. It will not start unless the clutch is fully depressed.
280 STARTING AND OPERATING
If Engine Fails To Start If the engine fails to start after you have followed the normal starting procedure, it may be flooded. Push the accelerator pedal all the way to the floor and hold it there while cranking the engine. This should clear any excess fuel in case the engine is flooded.
CAUTION!
To prevent damage to the starter, do not crank the engine for more than 15 seconds at a time. Wait 10 to 15 seconds before trying again.
WARNING!
Never pour fuel or other flammable liquids into the throttle body air inlet opening in an attempt to start the vehicle. This could result in a flash fire causing serious personal injury.
WARNING!
Do not attempt to push or tow your vehicle to get it started. Vehicles equipped with an automatic trans- mission cannot be started this way. Unburned fuel could enter the catalytic converter and once the engine has started, ignite and damage the converter and vehicle. If the vehicle has a discharged battery, booster cables may be used to obtain a start from a booster battery or the battery in another vehicle. This type of start can be dangerous if done improperly. Refer to “Jump Starting” in Section 6.
STARTING AND OPERATING 281
If the engine has been flooded, it may start to run, but not have enough power to continue running when the key is released. If this occurs, continue cranking with the accel- erator pedal pushed all the way to the floor. Release the accelerator pedal and the key once the engine is running smoothly. If the engine shows no sign of starting after two 15- second periods of cranking with the accelerator pedal held to the floor, the normal starting procedure should be repeated. After Starting The idle speed is automatically controlled and will de- crease as the engine warms up.
282 STARTING AND OPERATING
ENGINE BLOCK HEATER — IF EQUIPPED The engine block heater warms engine coolant and permits quicker starts in cold weather. Connect the cord to a standard 110-115 volt AC electrical outlet with a grounded, three-wire extension cord. The engine block heater cord is routed under the hood on the driver side of the vehicle. It has a removable cap that is located on the driver’s side of the Integrated Power Module.
WARNING!
Remember to disconnect the cord before driving. Damage to the 110-115 volt electrical cord could cause electrocution.
AUTOMATIC TRANSMISSION
CAUTION!
a complete stop.
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.
WARNING!
It is dangerous to shift the shift lever out of PARK or NEUTRAL 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 reverse. 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 lever display located in the instrument panel cluster indicates the transmission gear range (the selector is illuminated for night driving). The shift lever is mounted on the right side of the steering column. You must depress the brake pedal to pull the shift lever out of PARK position (Brake Interlock System). To drive, move
STARTING AND OPERATING 283
the shift lever from PARK or NEUTRAL to the desired DRIVE position. Pull the shift 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. 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!
284 STARTING AND OPERATING
WARNING!
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.
WARNING!
Your vehicle could move and injure you and others if it is not completely in PARK. Check by trying to move the gearshift lever back and forth without first pulling it toward you after you have set it in PARK. Make sure it is in PARK before leaving the vehicle.
It is dangerous to shift the shift lever out of PARK or NEUTRAL 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 reverse. 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.
REVERSE Use this range only after the vehicle has come to a complete stop.
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. DRIVE This position provides all forward gears, including 3rd gear direct and 4th or 5th gear overdrive (see Overdrive Operation). Use this range for most city and highway driving. 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.
STARTING AND OPERATING 285
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 SECOND or FIRST gear selections in high ambients as torque converter slip can impose significant additional heat load on the cooling system. Overdrive Operation The overdrive automatic transmission contains an elec- tronically controlled fourth and fifth (if equipped) speed (Overdrive). The transmission will automatically shift from DRIVE to Overdrive if the following conditions are present: † the transmission selector is in DRIVE;
286 STARTING AND OPERATING

km/h);
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.
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).
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
STARTING AND OPERATING 287
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.
288 STARTING AND OPERATING
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.
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.
CAUTION!
Shifting — 2500/3500 Models
STARTING AND OPERATING 289
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.
NOTE: During cold weather, you may experience in- creased effort in shifting until the transmission fluid warms up. This is normal.
Shift Pattern
Truck models with manual transmission are equipped with a clutch interlocking ignition system. The clutch pedal must be fully depressed to start the vehicle.
290 STARTING AND OPERATING
Fully depress the clutch pedal before shifting gears. As you release the clutch pedal, lightly depress the accelera- tor pedal. 2500 and 3500 models are 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.
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.

(81)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. Downshift progressively. Do not skip gears to avoid overspeeding the engine and clutch.
WARNING!
Do not downshift for additional engine braking on a slippery surface. The drive wheels could lose their grip and the vehicle could skid.
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, and/or clutch disc damage even if the clutch pedal is depressed.
Maximum Recommended Downshift Speeds
CAUTION!
Failure to follow the recommended downshifting speeds may cause the engine to overspeed and/or damage the clutch disc even if the clutch pedal is depressed.

Reverse Shifting To shift into REVERSE (R), bring the vehicle to a com- plete stop. Depress the clutch and pause briefly to allow the gear train to stop rotating. Beginning from the NEUTRAL (N) position, move the shift lever in one quick smooth motion straight across and into the REVERSE (R) area (the driver will feel a firm “click” as the shifter passes the “knock-over”). Complete the shift by pulling the shift lever into REVERSE (R).
294 STARTING AND OPERATING
The “knock-over” prevents the driver from accidentally entering the REVERSE (R) shift area and warns the driver that they are about to shift the transmission into RE- VERSE (R). Due to this feature, a slow shift to REVERSE (R) can be perceived as a high shift effort. On 2500/3500 models, when shifting out of reverse bring the vehicle to a complete stop and depress the clutch. Shifting out of reverse prior to a complete stop may cause high shift effort.
FOUR-WHEEL DRIVE OPERATION — IF EQUIPPED Four-wheel drive trucks are equipped with either a manually shifted transfer case or an electronically shifted transfer case. Refer to the operating instructions for your transfer case, located in 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 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 295
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.
296 STARTING AND OPERATING
WARNING!
You or others could be injured if you leave the vehicle unattended with the transfer case in the NEUTRAL position without first fully engaging the parking brake. The transfer case NEUTRAL 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 drive- shafts from the powertrain. To be used for flat towing behind another vehicle. See Recreational Towing for more information. 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 297
vehicle in motion, the transfer case will engage/ disengage faster if you momentarily release the accelera- tor 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 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 NEUTRAL. NOTE: Pausing in transfer case 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 NEUTRAL, hold foot on brake, and turn engine OFF. Make shift to the desired mode.
298 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 4-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 (5 Position Switch) — If Equipped
5 Position Switch
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.
This Electronically Shifted transfer case provides 5 mode positions: 2-wheel drive (2WD), 4WD AUTO, 4WD LOCK, NEUTRAL and 4WD LOW. The Electronically Shifted transfer case is designed to be driven in the 2 wheel drive position (2WD) or 4-wheel drive position (4WD AUTO) for normal street and high- way conditions (dry hard surfaced roads). Driving the vehicle in 2WD will have greater fuel economy benefits, as the front axle is not engaged in 2WD. For variable driving conditions the 4WD AUTO mode can be used. In this mode the front axle is engaged, but the vehicle’s power is sent to the rear wheels. 4-wheel drive will be automatically engaged when the vehicle senses a loss of traction. Because the front axle is en- gaged, this mode will result in lower fuel economy than the 2WD mode.
STARTING AND OPERATING 299
When additional traction is required, the transfer case 4WD LOCK and 4WD LOW 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 4WD LOCK and 4WD LOW positions are designed for loose, slippery road surfaces only. Driving in the 4WD LOCK and 4WD LOW positions on dry hard surfaced roads may cause in- creased tire wear and damage to the driveline compo- nents.

NEUTRAL Button
NOTE: The transfer case NEUTRAL position is selected by depressing the recessed button located on the lower left hand corner of the 4WD Control Switch. The transfer case NEUTRAL position is to be used for recreational towing only. See the Recreational Towing section for specific procedures on shifting into and out of NEUTRAL.
Transfer Case Position Indicator Lights — Electronically Shifted Transfer Case Only Transfer case position indicator lights are located on the instrument cluster and indicate the current and desired transfer case selection. When you select a different trans- fer case position, the indicator lights will do the follow- ing: 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. 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 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
STARTING AND OPERATING 301
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. This could cause damage to driveline components.
302 STARTING AND OPERATING
When operating your vehicle in 4WD LO, the engine speed is approximately three times that of the 2WD, 4WD AUTO or 4WD HI 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 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 position without first fully engaging the parking brake. The transfer case NEUTRAL position disengages both the front and rear driveshafts from the powertrain and will allow the vehicle to move regardless of the transmission position.
