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.

234 UNDERSTANDING YOUR INSTRUMENT PANEL

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 separator

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.

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.

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.

248 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 direction. 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.

Operating Tips

Fast Cooldown For a fast cooldown, turn the blower fan rotary knob to the extreme right position, turn the mode control to the panel fresh position, press the snowflake button to turn on the air conditioning, and drive with the windows open for the first few minutes. Once the hot air has been expelled, close the windows and press the recirculation pushbutton, on dual-zone control, or switch the mode from panel/fresh to panel/recirculate on single-zone control. When a comfortable condition has been reached, choose a mode position and adjust the temperature control slide and blower speed as necessary to maintain comfort. For high humidity conditions it may be neces- sary to remain in the Recirculation mode to maintain comfort.

Window Fogging Windows will fog on the inside when the humidity inside the vehicle is high. This often occurs in mild or cool temperatures when it’s rainy or humid. In most cases turning on the air conditioning (pressing the snowflake button) will clear the fog. Adjust the temperature control, air direction and blower speed to maintain comfort. As the temperature gets colder it may be necessary to direct air onto the windshield by using MIX Mode position on the control. Adjust the temperature control and blower speed to maintain comfort. Higher blower speeds will reduce fogging. Interior fogging on the windshield can be quickly removed by selecting the defrost mode. Regular cleaning of the inside of the windows with a non-filming cleaning solution (vinegar and water works very well) will help prevent contaminates (cigarette smoke, perfumes, etc.) from sticking to the windows. Contaminates increase the rate of window fogging.

Summer Operation Air conditioned vehicles must be protected with a high quality antifreeze coolant during summer to provide proper corrosion protection and to raise the boiling point of the coolant for protection against overheating. A 50 % concentration is recommended. 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.

UNDERSTANDING YOUR INSTRUMENT PANEL 261

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.

268 STARTING AND OPERATING

STARTING PROCEDURES – DIESEL 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 minutes 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 shift 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 build up may cause serious injury or death.

Automatic Transmission – If Equipped Start the engine with the shift lever in NEUTRAL or PARK position. Apply the brake before shifting to any driving range. The Cumminst Diesel engine is equipped with several features designed to assist cold weather starting and operation: † The engine block heater is a resistance heater installed in the water jacket of the engine just above and behind the oil filter. It requires a 110–115 volt AC electrical outlet with a grounded, three-wire extension cord.

NOTE: The engine block heater cord is a factory in- stalled option. If your vehicle is not equipped, heater cords are available from your authorized Mopart dealer. † A 12–volt heater built into the fuel filter housing aids in preventing fuel gelling. It is controlled by a built-in thermostat. † A heated intake air system both improves engine starting and reduces the amount of white smoke generated by a warming engine.

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.

STARTING AND OPERATING 269

Normal Starting Procedure – Engine Manifold Air Temperature Above 66°F (19°C) Observe the instrument panel cluster lights when starting the engine. 1. Always apply the parking brake. 2. Shift into PARK for an automatic transmission. For vehicles equipped with manual transmissions, fully de- press and hold the clutch pedal and shift into NEUTRAL. 3. Turn the ignition key to the ON position and watch the instrument panel cluster lights.

270 STARTING AND OPERATING

CAUTION!

If WATER IN FUEL indicator light remains on DO NOT START engine before you drain water from the fuel filter to avoid engine damage. Refer to “Drain- ing Fuel/Water Separator Filter (6.7L Diesel Engine)” under “Maintenance Procedures” in Section 7.

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

CAUTION!

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

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

NOTE: The temperature displayed on the overhead console (if equipped) does not necessarily reflect the engine manifold air temperature. When certain engine temperatures fall below 66°F (19°C) the lights will remain on indicating the intake manifold heater system is active.

Follow the steps in the Normal Starting Procedure ex- cept:

CAUTION!

Do not crank engine for more than 15 seconds at a time or starter motor damage may result. Turn key to OFF and wait at least two minutes for starter to cool before repeating start procedure.

† The WAIT TO START light will remain on for a period of time (length of time depends on engine tempera- ture). † After the WAIT TO START light goes off, turn the ignition key to START. Do not press the accelerator during starting.

STARTING AND OPERATING 271

pressure.

† After engine start-up, check to see that there is oil † Allow the engine to idle about three minutes until the manifold heaters have completed the post-heat cycle.

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

272 STARTING AND OPERATING

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

† If the engine stalls after the initial start, the ignition must be turned to the OFF position for at least five seconds and then to the ON position to recycle the manifold heaters.

NOTE: Excessive white smoke and poor engine perfor- mance will result if manifold heaters are not recycled. † Heat generated by the manifold heaters dissipates rapidly in a cold engine. If more than two minutes pass between the time the WAIT TO START light goes OFF and the engine is started, recycle the manifold heaters by turning the ignition OFF for at least five seconds and then back ON. † If the vehicle is driven and vehicle speed exceeds 19
mph (31 km/h) before the manifold heater post-heat (after start) cycle is complete, the manifold heaters will shut off.

† If the engine is started before the WAIT TO START † If the engine is cranked for more than 10 seconds, the

light turns off, the preheat cycle will turn off.

post-heat cycle will turn off.

NOTE: Engine idle speed will automatically increase to 1000 RPM at low coolant temperatures to improve engine warm-up. NOTE: When a diesel engine is allowed to run out of fuel or the fuel gels at low temperatures, air is pulled into the fuel system. You may try priming as described below: 1. Add a substantial quantity of fuel to the tank (5 to 10
gal) (19 to 38 L) or eliminate the gelled fuel condition. 2. Crank the engine for one to two seconds. If the engine does not start, then turn the ignition back to the RUN position (do not turn the ignition back to the OFF

STARTING AND OPERATING 273

position). The electric fuel transfer pump will continue to run and purge air from the system for about 20 seconds. After 20 seconds, attempt to start the engine again. 3. Start the engine using the Normal Starting Procedure. 4. Repeat the procedure if the engine does not start.

WARNING!

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

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

274 STARTING AND OPERATING

Starting Fluids

WARNING!

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

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

WARNING!

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

NORMAL OPERATION (DIESEL ENGINE) Observe the following when the engine is operating. † All message center lights are off. † Check Engine Lamp is off. † Engine Oil Pressure is above 10 psi (69 kPa) at idle. † Low Oil Pressure light is off.

† Voltmeter Operation: 1. The voltmeter may show a gauge fluctuation if certain engine temperatures are below 66°F (19°C). This cycling operation is caused by the post-heat cycle of the intake manifold heater system. The number of cycles and the length of the cycling operation is controlled by the engine control module. Post-heat operation can run for several minutes, and then the electrical system and voltmeter needle will stabilize. 2. The cycling action will cause temporary dimming of the headlamps, interior lamps, and also a noticeable reduction in blower motor speed.

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

STARTING AND OPERATING 275

Fuel Operating Range (6.7L Diesel Engine) NOTE: Use “Ultra Low Sulfur Diesel Fuels” ONLY.

*No. 1 Ultra Low Sulfur diesel fuel should only be used where extended arctic conditions (-10°F/-23°C) exist. NOTE: † Use of Climatized Ultra Low Sulfur Diesel Fuel or Number 1 Ultra Low Sulfur Diesel Fuel results in a noticeable decrease in fuel economy.

276 STARTING AND OPERATING

† Climatized Ultra Low Sulfur Diesel Fuel is a blend of Number 2 Ultra Low Sulfur and Number 1 Ultra Low Sulfur Diesel Fuels which reduces the temperature at which wax crystals form in fuel.

NOTE: The engine requires the use of “Ultra Low Sulfur Diesel Fuel”. Use of incorrect fuel could result in engine and exhaust system damage. Refer to Fuel Re- quirements in this section for further details on fuel recommendations. Engine Block Heater The engine block heater warms engine coolant and permits quicker starts in cold weather. Connect the heater cord to a ground–fault interrupter protected 110–115 volt AC electrical outlet with a grounded, three-wire exten- sion cord. The engine block heater cord is routed under the hood to the right side and can be located just behind the grille near the headlamp.

NOTE: The engine block heater cord is a factory in- stalled option. If your vehicle is not equipped, heater cords are available from your authorized Mopart dealer. The block heater must be plugged in at least one hour to have an adequate warming effect on the coolant.

WARNING!

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

NOTE: The block heater will require 110 Volts AC and 6.5 Amps to activate the heater element.

Block Heater Usage A. Temperatures below 0°F (-18°C) † Block Heater Required for 15W-40
† Block Heater Recommended for 5W-40
B. Temperatures below - 20°F (-29°C) † Block Heater Required for 5W-40
Winter Front Usage If a winter front or cold weather cover is to be used, a percentage of the total grille opening area must be left uncovered to provide sufficient air flow to the charge air cooler and automatic transmission oil cooler. The per- centage of opening must be increased with the increasing ambient air temperature and/or engine load. If the cooling fan can be heard cycling frequently, increase the size of the opening in the winter front. A suitable cold weather cover is available from your Mopart dealer.

STARTING AND OPERATING 277

Battery Blanket Usage A battery loses 60% of its cranking power as the battery temperature decreases to 0°F (-18°). For the same de- crease in temperature, the engine requires twice as much power to crank at the same RPM. The use of 120 VAC powered battery blankets will greatly increase starting capability at low temperatures. Suitable battery blankets are available from your authorized Mopart dealer. Arctic Operation Where there are no provisions to keep the engine warm when it is operating in ambient temperatures consistently below (-10°F/-23°C), use 5W-40 synthetic engine oil and fuel that meets the requirements in Section 7, “Mainte- nance Procedures,” Engine Oil Selection. Engine Warm-Up Avoid full throttle operation when the engine is cold. When starting a cold engine, bring the engine up to operating speed slowly to allow the oil pressure to stabilize as the engine warms up.

278 STARTING AND OPERATING

NOTE: High-speed, no-load running of a cold engine can result in excessive white smoke and poor engine performance. No-load engine speeds should be kept under 1,200 rpm during the warm-up period, especially in cold ambient temperature conditions. If temperatures are below 32°F (0°C), operate the engine at moderate speeds for 5 minutes before full loads are applied. Engine Idling Avoid prolonged idling, long periods of idling may be harmful to your engine because combustion chamber temperatures can drop so low that the fuel may not burn completely. Incomplete combustion allows carbon and varnish to form on piston rings and injector nozzles. Also, the unburned fuel can enter the crankcase, diluting the oil and causing rapid wear to the engine.

CAUTION!

Extended periods of idle time may not allow the vehicle’s exhaust aftertreatment system to properly regenerate. This can lead to the illumination of the Malfunction Indicator Light (MIL) or an Electronic Vehicle Information Center (EVIC) warning message. Operating the engine for extended periods with the MIL illuminated or an EVIC warning message dis- played can cause extensive engine and exhaust sys- tem damage.

NOTE: Your vehicle is equipped with a turbo speed limiter, this feature limits the engine speed to 1200 rpm when engine coolant temperatures are below 70°F (21°C). This feature is designed to protect the turbo charger from damage and will only operate in PARK or NEUTRAL.

NOTE: An optional driver-controlled high idle speed is available on automatic transmission equipped vehicles with speed control. This feature allows the driver to select an elevated idle speed between 1100 and 1500
rpms. Your dealer can enable this feature. The optional driver-controlled high idle speed will help increase cylinder temperatures and provide additional cab heat, however, may still cause the exhaust aftertreat- ment system to not properly regenerate. Extended peri- ods of idle time should be avoided. NOTE: † If ambient

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

STARTING AND OPERATING 279

† foot is off brake pedal and throttle pedal † automatic transmission is in Park (P) † vehicle speed is zero † Applying the throttle will cancel fast idle † If the engine is equipped with an exhaust brake, operating the exhaust brake at idle will greatly im- prove warm up rate and will help keep the engine close to operating temperature during extended idle.

CAUTION!

Use of aftermarket exhaust brakes is not recom- mended and could lead to engine damage

280 STARTING AND OPERATING

Stopping The Engine Idle the engine a few minutes before routine shutdown. After full load operation, idle the engine 3 to 5 minutes before shutting it down. This idle period will allow the lubricating oil and coolant to carry excess heat away from the combustion chamber, bearings, internal components, and turbocharger. This is especially important for turbo- charged, charge air cooled engines. NOTE: During engine shutdown on vehicles equipped with manual transmissions, it is normal for the diesel engine to resonate heavily for a moment during engine shut off. When the engine is connected to a manual transmission, this resonance causes loud gear rattle from the transmission. This is commonly referred to as “shut down rattle”. The manufacturer recommends performing engine shut down with the clutch pedal pushed to the floor (clutch disengaged). When engine shut down is performed in this manner the rattle is reduced (not eliminated).

CAUTION!

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

Operating Precautions

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

STARTING AND OPERATING 281

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

282 STARTING AND OPERATING

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

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

CAUTION!

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

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

the engine operating temperature

DIESEL EXHAUST BRAKE (ENGINE BRAKING) – IF EQUIPPED The exhaust brake feature will only function when the driver turns the exhaust brake switch to the ON position. Once the switch is in the ON position and the vehicle is moving faster than 5 mph (8 km/h); the exhaust brake will automatically operate when the driver removes pressure from the accelerator pedal. Exhaust braking is most effective when the engine RPM is higher. The automatic transmission has been programmed to down- shift more aggressively when the exhaust brake is en- abled to increase brake performance.

STARTING AND OPERATING 283

Exhaust Brake Switch

284 STARTING AND OPERATING

WARNING!

Do not use the Exhaust Brake feature when driving in icy or slippery conditions as the increased engine braking can cause the rear wheels to slide and the vehicle to swing around with the possible loss of vehicle control, which may cause an accident possi- bly resulting in personal injury or death.

NOTE: For optimum braking power it is recommended to use the Exhaust Brake while in Tow/Haul Mode. The purpose of the exhaust brake (engine braking) fea- ture is to supply negative (braking) torque to the engine. Typically, the engine braking is used for, but not limited to, vehicle towing applications where vehicle braking can be achieved by the internal engine power, thereby spar- ing the mechanical brakes of the vehicle.

Benefits of the exhaust brake are: † vehicle driving control † reduced brake fade † longer brake life † faster cab warm-up. The exhaust brake feature can also be used to reduce the engine warm up time. To use the exhaust brake as a warm-up device, the vehicle must be moving less than 5
mph (8 km/h), the exhaust brake switch must be in the ON position, and the coolant temperature must below 180°F (82°C) and ambient temperature below 60°F (16°C).

TRANSMISSION SHIFTING

Automatic Transmission with Overdrive (68RFE) — If Equipped The gear selector lever 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 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.

STARTING AND OPERATING 285

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!

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.

286 STARTING AND OPERATING

WARNING!

Your vehicle could move and injure you and others if it is not completely in PARK. Check by trying to move the shift 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.

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.

REVERSE Use this range only after the vehicle has come to a complete stop. NEUTRAL Shift to NEUTRAL when the vehicle is standing for prolonged periods with the engine running. The engine may be started in this range. Set the parking brake if you must leave the vehicle. DRIVE Drive range provides underdrive 1st, 2nd and 3rd gears, direct 4th gear and overdrive 5th and 6th gears. The shift into overdrive 5th and 6th gear occurs only after the transmission has completed the shift into 4th gear. No other movement of the shift mechanism is required to complete the 4–5 or 5–6 gear shifts. The 4th and 5th gear upshifts occurs automatically unless the Tow/Haul mode is enabled.

Upshifts into both overdrive gears, 5th and 6th, will be delayed when the transmission fluid temperature is below 40° F (4.5° C) or above 240° F (115.5° C). NOTE: Use caution when operating a heavily loaded vehicle in 2nd or 1st gear in high ambients as torque converter slip can impose significant additional heat load on the cooling system.

WARNING!

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

STARTING AND OPERATING 287

Overdrive Operation The overdrive automatic transmission contains an elec- tronically controlled 5th and 6th (Overdrive). The trans- mission will automatically shift from Drive to Overdrive if the following conditions are present: † the transmission selector is in DRIVE; † the engine coolant has reached normal operating tem- † vehicle speed is above approximately 30 mph (48
† the “TOW HAUL O/D OFF” switch has not been † transmission has reached normal operating tempera-

ture.

288 STARTING AND OPERATING

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

1 — Tow/Haul Switch 2 — AUTO-6 (ERS) Switch When driving in hilly areas, towing a trailer, carrying a heavy load, etc., and frequent transmission shifting oc- curs, press the TOW HAUL button once to select TOW HAUL. In TOW HAUL mode, 4th to 5th gear upshifts are

delayed. Shifts into 5th and 6th gear are still allowed under steady cruise conditions. Closed throttle down- shifts (for improved engine braking) may occur during steady braking maneuvers. Pressing the switch a second time restores normal operation. Normal operation is always the default at engine start-up. The TOW HAUL light will illuminate in the instrument cluster to indicate when the switch has been activated. If the TOW HAUL modes are desired, the button must be pressed each time the engine is started. Electronic Range Select (ERS) Operation The Auto–6 Electronic Range Select (ERS) shift control allows you to move the switch down (-) or up (+) when the shifter is in the D (Drive) position, allowing the selection of the desired top gear. For example, if the driver shifts the transmission into 3rd gear, the transmis- sion will never shift above 3rd gear, but can shift down to 2nd or 1st gear, when needed.

STARTING AND OPERATING 289

Switching from ERS to D-Mode can be done at any vehicle speed. To switch from “Drive” mode to “ERS” mode, press the switch down (-) once. The current gear will be maintained as the top gear. To disable ERS, simply press and hold the switch up (+) until “D” is displayed in the instrument cluster odometer.

WARNING!

Do not downshift for additional engine braking on a slippery surface. The drive wheels could lose their grip and the vehicle could skid.

290 STARTING AND OPERATING

NOTE: To select the proper gear position for maximum deceleration (engine braking), simply press and hold the switch down (-). The transmission will shift to the range from which the vehicle can best be slowed down. 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!

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.

STARTING AND OPERATING 291

NOTE: During cold weather, you may experience in- creased effort in shifting until the transmission fluid warms up. This is normal. Shifting

Shift Pattern

292 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. This transmission has a “creeper” 1st gear (L=low) 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. You should use 1st gear when starting from a standing position if under heavy load or when pulling a trailer.

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. When heavily loaded or pulling a trailer these recommended up-shift speeds may not apply. Maximum Recommended Up-shift Speeds

Downshifting

Moving from a high gear down to a lower gear is recommended to preserve brakes when driving down steep hills. In addition, downshifting at the right time provides better acceleration when you desire to resume speed. Downshift progressively. Do not skip gears to avoid overspeeding the engine and clutch.

STARTING AND OPERATING 293

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.

WARNING!

Maximum Recommended Downshift Speeds

Do not downshift for additional engine braking on a slippery surface. The drive wheels could lose their grip and the vehicle could skid.

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.

km/h) 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). 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. To shift 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. See the operating instructions for your transfer case, located within this section. Manually Shifted Transfer Case Operating Information/Precautions The transfer case provides 4 mode positions - 2 (rear)- wheel drive high range, 4-wheel drive high range, neu- tral, and 4-wheel drive low range.

This transfer case is intended to be driven in the 2-wheel drive position (2H) for normal street and highway con- ditions such as dry hard surfaced roads. When additional traction is required the transfer case 4H and 4L positions can be used to lock the front and rear driveshafts together and force the front and rear wheels to rotate at the same speed. This is accomplished by simply moving the shift lever to the desired positions. The 4H and 4L positions are intended for loose, slippery road surfaces only. Driving in the 4H and 4L positions on dry hard surfaced roads may cause increased tire wear and damage to the driveline components. The 4-wheel drive light (4WD), located in the instrument cluster, alerts the driver that the vehicle is in 4-wheel drive and that the front and rear driveshafts are locked together. This light illuminates when the transfer case is shifted to either the 4H or 4L positions. There is no light for the 2H or NEUTRAL positions.

STARTING AND OPERATING 295

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. 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.

296 STARTING AND OPERATING

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.

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

298 STARTING AND OPERATING

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.

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