TARTING

LUIDS

The engine is equipped with a glow plug preheating

system. If the instructions in this manual are

followed, the engine should start in all conditions

and no type of starting fluid should be used.

NORMAL OPERATION — DIESEL ENGINE

Observe the following when the diesel engine is

operating:



All message center lights are off.



Malfunction Indicator Light (MIL) is off.



Engine Oil Pressure telltale is not illuminated.



Voltmeter operation.

The voltmeter may show a gauge fluctuation at

various engine temperatures. This is caused by the

glow plug heating system. The number of cycles

and the length of the cycling operation is controlled

by the engine control module. Glow plug heater

operation can run for several minutes. Once the

heater operation is complete the voltmeter needle

will stabilize.

NOTE:

Use Ultra Low Sulfur Diesel (ULSD) Fuels ONLY.

WARNING!



Do not leave children or animals inside parked

vehicles in hot weather. Interior heat build-up

may cause serious injury or death.



When leaving the vehicle, always make sure

the keyless ignition node is in the OFF posi

tion, remove the key fob from the vehicle and

lock the vehicle.



Never leave children alone in a vehicle, or with

access to an unlocked vehicle. Allowing chil

dren to be in a vehicle unattended is

dangerous for a number of reasons. A child or

others could be seriously or fatally injured.

Children should be warned not to touch the

parking brake, brake pedal or the gear

selector.



Do not leave the key fob in or near the vehicle,

or in a location accessible to children, and do

STARTING AND OPERATING

Fuel Operating Range Chart

*Number 1 ULSD Fuel should only be used where

extended arctic conditions 0°F (-18°C) exist.

NOTE:



Use of Climatized ULSD Fuel or Number 1 ULSD

fuel results in a noticeable decrease in fuel

economy.



Climatized ULSD fuel is a blend of Number 2

ULSD fuel and Number 1 ULSD fuel which

reduces the temperature at which wax crystals

form in fuel.



The fuel grade should be clearly marked on the

pump at the fuel station.



The engine requires the use of Ultra Low Sulfur

Diesel Fuel. Use of incorrect fuel could result in

engine and exhaust system damage

page 454.



If climatized or Number 1 ULSD fuel is not avail

able, and you are operating below 20°F (-6°C),

in sustained arctic conditions, Mopar®

Premium Diesel Fuel Treatment (or equivalent)

is recommended to avoid gelling (see Fuel Oper

ating Range Chart).

Engine Oil Usage

See Engine Fluids and Lubricants for the correct

engine oil viscosity

page 458.

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.
If temperatures are below 32°F (0°C), operate the

engine at moderate speeds for five minutes before

full loads are applied.

NGINE

DLING

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, cylinder head valves, turbocharger,

and injector nozzles. Also, the unburned fuel can

enter the crankcase, diluting the oil and causing

rapid wear to the engine.

STARTING AND OPERATING

157

TOPPING

NGINE

After full load operation, idle the engine for a few minutes before shutting it down. This idle period will allow the lubricating oil and coolant to carry excess heat

away from the turbocharger.

NOTE:

Refer to the following chart for proper engine shutdown.

NOTE:

Under certain conditions the engine stop/start functionality may be temporarily disabled and the engine fan will run after the engine is turned off to protect the

engine. These conditions are under high load and high temperature conditions.

RANSMISSION

To reduce the potential for engine and

transmission overheating in high ambient

temperature conditions, take the following actions:



City Driving — When stopped, shift the transmis

sion into NEUTRAL (N) and increase engine idle

speed.



Highway Driving — Reduce your speed.



Up Steep Hills — Select a lower transmission

gear.



Air Conditioning — Turn it off temporarily.

NOTE:

If the coolant temperature is too high, the A/C will

automatically turn off.

Do Not Operate The Engine With Low Oil

Pressure

If the Low Oil Pressure Warning Light turns on while

driving, stop the vehicle and shut down the engine

as soon as possible. After the vehicle is safely

stopped, restart the engine and monitor the lamp.

If the lamp is still illuminated, shut the engine off,

contact an authorized dealer, and do not operate

the vehicle until the cause is corrected. If the lamp

is no longer illuminated, the engine can be

operated, but should be taken to an authorized

dealer as soon as possible for further inspection.

NOTE:

Do not operate the vehicle until the cause is

corrected. This light does not show how much oil is

in the engine. The engine oil level must be checked

under the hood.

Do Not Operate The Engine With Failed

Parts

All engine 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 the engine operating temperature



Excessive smoke



Oil pressure drop

ENGINE BREAK-IN RECOMMENDATIONS —

GASOLINE ENGINE (IF EQUIPPED)

A long break-in period is not required for the engine

and drivetrain (transmission and axle) in your

vehicle.
Drive moderately during the first 300 miles

(500 km). After the initial 60 miles (100 km),

speeds up to 50 or 55 mph (80 or 90 km/h) are

desirable.
While cruising, brief full-throttle acceleration within

the limits of local traffic laws contributes to a good

break-in. Wide-open throttle acceleration in low

gear can be detrimental and should be avoided.
The engine oil installed in the engine at the factory

is a high-quality energy conserving type lubricant.

Oil changes should be consistent with anticipated

climate conditions under which vehicle operations

will occur.
For the recommended viscosity and quality grades

see

page 458.

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.

CAUTION!

Never use Non-Detergent Oil or Straight Mineral

Oil in the engine or damage may result.

STARTING AND OPERATING

159

NOTE:

A new engine may consume some oil during its first

few thousand miles (kilometers) of operation. This

should be considered a normal part of the break-in

and not interpreted as a problem.

ENGINE BREAK-IN RECOMMENDATIONS —

DIESEL ENGINE (IF EQUIPPED)

The diesel engine does not require a break-in

period due to its construction. Normal operation is

allowed, providing the following recommendations

are followed:



Warm up the engine before placing it under

load.



Do not operate the engine at idle for prolonged

periods.



Use the appropriate transmission gear to

prevent engine lugging.



Observe vehicle oil pressure and temperature

indicators.



Check the coolant and oil levels frequently.



Vary throttle position at highway speeds when

carrying or towing significant weight.

NOTE:

Light duty operation such as light trailer towing or

no load operation will extend the time before the

engine is at full efficiency. Reduced fuel economy

and power may be seen at this time.
The engine oil installed in the engine at the factory

is a high-quality energy conserving type lubricant.

Oil changes should be consistent with anticipated

climate conditions under which vehicle operations

will occur. For recommended viscosity and quality

grades

page 458. NON-DETERGENT OR

STRAIGHT MINERAL OILS MUST NEVER BE USED.

PARKING BRAKE

Before exiting the vehicle, make sure that the

parking brake is fully applied. Also, be certain to

leave an automatic transmission in PARK, or

manual transmission in REVERSE or FIRST gear.
The parking brake lever is located in the center

console. To apply the parking brake, pull the lever

up as firmly as possible. To release the parking

brake, pull the lever up slightly, push the center

button, then lower the lever completely.

Parking Brake Lever

When the parking brake is applied with the ignition

switch ON, the Brake Warning Light in the

instrument cluster will illuminate.

NOTE:



When the parking brake is applied and the auto

matic transmission is placed in gear, the Brake

Warning Light will flash. If vehicle speed is

detected, a chime will sound to alert the driver.

Fully release the parking brake before

attempting to move the vehicle.



This light only shows that the parking brake is

applied. It does not show the degree of brake

application.

STARTING AND OPERATING

(Continued)

When parking on a hill, it is important to turn the

front wheels toward the curb on a downhill grade

and away from the curb on an uphill grade. For

vehicles equipped with an automatic transmission,

apply the parking brake before placing the gear

selector in PARK, otherwise the load on the

transmission locking mechanism may make it

difficult to move the gear selector out of PARK.

MANUAL TRANSMISSION — IF EQUIPPED

WARNING!



Never use the PARK position on an automatic

transmission as a substitute for the parking

brake. Always apply the parking brake fully

when parked to guard against vehicle move

ment and possible injury or damage.



When exiting the vehicle, always remove the

key fob from the vehicle and lock your vehicle.



Never leave children alone in a vehicle, or with

access to an unlocked vehicle. Allowing chil

dren to be in a vehicle unattended is

dangerous for a number of reasons. A child or

others could be seriously or fatally injured.

Children should be warned not to touch the

parking brake, brake pedal or the gear

selector.



Do not leave the key fob in or near the vehicle,

or in a location accessible to children. A child

could operate power windows, other controls,

or move the vehicle.



Be sure the parking brake is fully disengaged

before driving; failure to do so can lead to

brake failure and a collision.



Always fully apply the parking brake when

leaving your vehicle or it may roll and cause

damage or injury. Also, be certain to leave an

automatic transmission in PARK, a manual

transmission in REVERSE or FIRST gear.

Failure to do so may cause the vehicle to roll

and cause damage or injury.

CAUTION!

If the Brake Warning Light remains on with the

parking brake released, a brake system

malfunction is indicated. Have the brake system

serviced by an authorized dealer immediately.

WARNING!

You or others could be injured if you leave the

vehicle unattended without having the parking

brake fully applied. The parking brake should

always be applied when the driver is not in the

vehicle, especially on an incline.

CAUTION!



Never drive with your foot resting on or

partially pressing the clutch pedal. Never

attempt to hold the vehicle on a hill with the

clutch pedal partially engaged. Operating

vehicle in this manner may cause the clutch to

overheat and cause permanent damage to

the clutch. If you continue to operate the

vehicle in this manner, the “Clutch Hot”

message or Transmission Temperature

Warning Light will be displayed in the instru

ment cluster. For more information

page 138.



Do not drive with your hand resting on the gear

selector as the force exerted, even if slight,

could lead over time to premature wear of the

gearbox internal components.

STARTING AND OPERATING

161

NOTE:

During cold weather, you may experience

increased effort in shifting until the transmission

fluid warms up. This is normal.

Manual Transmission Shifter

To shift the gears, fully press the clutch pedal and

place the gear selector into the desired gear

position (the diagram for the engagement of the

gears is displayed on the handle of the selector).

The gear position will be displayed in the

instrument cluster.

To engage REVERSE gear from the NEUTRAL

position, lift the REVERSE ring, located below the

knob and move the gear selector all the way left

and then forward.

Shift Pattern

HIFTING

Fully press the clutch pedal before shifting gears.

As you release the clutch pedal, lightly press the

accelerator pedal.
You should always use FIRST gear when starting

from a standing position.

NOTE:

A certain amount of noise from the transmission is

normal. This noise can be most noticeable when

the vehicle is idling in NEUTRAL with the clutch

engaged (clutch pedal released), but it may also be

heard when driving. The noise may also be more

noticeable when the transmission is warm. This

noise is normal and is not an indication of a

problem with your clutch or transmission.

162

STARTING AND OPERATING

(Continued)

Recommended Vehicle Shift Speeds

To utilize your manual transmission efficiently for both fuel economy and performance, it should be upshifted as listed in the 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.

NOTE:

Vehicle speeds shown in the chart above are for

2H and 4H only. Vehicle speeds in 4L would be

significantly less.

OWNSHIFTING

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.

NOTE:

Above certain speeds, downshifts may be blocked

and not available.

Skipping gears and downshifting into lower

gears at higher vehicle speeds can damage

the engine and clutch systems. Any attempt to

shift into lower gear with clutch pedal pressed

may result in damage to the clutch system.

Shifting into lower gear and releasing the

clutch may result in engine damage.



When descending a hill, be very careful to

downshift one gear at a time to prevent over

speeding the engine which can cause engine

damage, and/or clutch damage, even if the

clutch pedal is pressed. If transfer case is in

low range the vehicle speeds to cause engine

and clutch damage are significantly lower.



Failure to follow the maximum recommended

downshifting speeds may cause engine

damage and/or damage the clutch, even if the

clutch pedal is pressed.

GNITION

ARK

NTERLOCK

This vehicle is equipped with an Ignition Park

Interlock system which requires the transmission

to be in PARK before the ignition can be turned to

the OFF position. This helps the driver avoid

inadvertently leaving the vehicle without placing

the transmission in PARK. This system also locks

the transmission in PARK whenever the ignition is

in the OFF position.

NOTE:

The transmission is NOT locked in PARK when the

ignition is in the ACC position (even though the

engine will be off). Ensure that the transmission is

in PARK, and the ignition is OFF (not in ACC

position) before exiting the vehicle.

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 your foot is firmly

pressing the brake pedal.



Unintended movement of a vehicle could

injure those in or near the vehicle. As with all

vehicles, you should never exit a vehicle while

the engine is running. Before exiting a vehicle,

always come to a complete stop, then apply

the parking brake, shift the transmission into

PARK, and turn the ignition OFF. When the

ignition is in the OFF position, the transmis

sion is locked in PARK, securing the vehicle

against unwanted movement.



When exiting the vehicle, always make sure

the ignition is in the OFF position, remove the

key fob from the vehicle, and lock the vehicle.

WARNING!



Never leave children alone in a vehicle, or with

UTOMATIC

RANSMISSION

The transmission gear range (PRNDM) is displayed

both beside the gear selector and in the

instrument cluster. To select a gear range, push

the lock button on the gear selector and move the

selector rearward or forward. To shift the

transmission out of PARK, the engine must be

running and the brake pedal must be pressed. You

must also press the brake pedal to shift from

NEUTRAL into DRIVE or REVERSE when the vehicle

is stopped or moving at low speeds. Select the

DRIVE range for normal driving.

NOTE:

In the event of a mismatch between the gear

selector position and the actual transmission gear

(for example, driver selects PARK while driving),

the position indicator will blink continuously until

the selector is returned to the proper position, or

the requested shift can be completed.
The electronically controlled transmission adapts

its shift schedule based on driver inputs, along

with environmental and road conditions. The

transmission electronics are self-calibrating;

therefore, the first few shifts on a new vehicle may

be somewhat abrupt. This is a normal condition,

and precision shifts will develop within a few

hundred miles (kilometers).

Only shift from DRIVE to PARK or REVERSE when

the accelerator pedal is released and the vehicle is

stopped. Be sure to keep your foot on the brake

pedal when shifting between these gears.
The transmission gear selector provides PARK,

REVERSE, NEUTRAL, DRIVE and MANUAL

(AutoStick) shift positions. Manual shifts can be

made using the AutoStick shift control. Toggling

the gear selector forward (-) or rearward (+) while

in the MANUAL (AutoStick) position (beside the

DRIVE position) will manually select the

transmission gear, and will display the current gear

in the instrument cluster

page 168.

Gear Selector

NOTE:

If the gear selector cannot be moved to the PARK,

REVERSE, or NEUTRAL position (when pushed

forward), it is probably in the AutoStick (+/-)

position (beside the DRIVE position). In AutoStick

mode, the transmission gear (1, 2, 3, etc.) is

displayed in the instrument cluster. Move the gear

selector to the right (into the DRIVE [D] position) for

WARNING!

STARTING AND OPERATING

167

The following indicators should be used to ensure

that you have properly engaged the transmission

into the PARK position:



When shifting into PARK, push the lock button

on the gear selector and firmly move the gear

selector all the way forward until it stops and is

fully seated.



Look at the transmission gear position display

and verify that it indicates the PARK position (P),

and is not blinking.



With the brake pedal released, verify that the

gear selector will not move out of PARK.

REVERSE (R)
This range is for moving the vehicle backward.

Shift into REVERSE only after the vehicle has come

to a complete stop.
NEUTRAL (N)
Use this range when the vehicle is standing for

prolonged periods with the engine running. Apply

the parking brake and shift the transmission into

PARK if you must exit the vehicle.

DRIVE (D)
This range should be used for most city and

highway driving. It provides the smoothest upshifts

and downshifts, and the best fuel economy. The

transmission automatically upshifts through all

forward gears. The DRIVE position should be used

for all normal operating conditions.
When frequent transmission shifting occurs (such

as when operating the vehicle under heavy loading

conditions, in hilly terrain, traveling into strong

head winds, or while towing a heavy trailer), use

the AutoStick shift control to select a lower gear

page 168. Under these conditions, using a lower

gear will improve performance and extend

transmission life by reducing excessive shifting

and heat build-up.
During extremely cold temperatures (-22°F

[-30°C] or below), transmission operation may be

modified depending on engine and transmission

temperature as well as vehicle speed. Normal

operation will resume once the transmission

temperature has risen to a suitable level.
MANUAL (M)
The MANUAL (M, +/-) position (beside the DRIVE

position) enables full manual control of

transmission shifting also known as AutoStick

mode. Toggling the gear selector forward (-) or

rearward (+) while in the MANUAL (AutoStick)

position will manually select the transmission gear,

and will display the current gear in the instrument

cluster

page 168.

Transmission Limp Home Mode

Transmission function is monitored electronically

for abnormal conditions. If a condition is detected

that could result in transmission damage,

Transmission Limp Home mode is activated. In this

mode, the transmission may operate only in

certain gears, or may not shift at all. Vehicle

performance may be severely degraded and the

engine may stall. In some situations, the

transmission may not re-engage if the engine is

turned off and restarted. The Malfunction Indicator

Light (MIL) may be illuminated. A message in the

instrument cluster will inform the driver of the

more serious conditions, and indicate what actions

may be necessary.

WARNING!

Do not coast in NEUTRAL and never turn off the

ignition to coast down a hill. These are unsafe

practices that limit your response to changing

traffic or road conditions. You might lose control

of the vehicle and have a collision.

CAUTION!



Towing the vehicle, coasting, or driving for any

other reason with the transmission in

NEUTRAL can cause severe transmission

damage.

STARTING AND OPERATING

In the event of a momentary problem, the

transmission can be reset to regain all forward

gears by performing the following steps:

NOTE:



In cases where the instrument cluster message

indicates the transmission may not re-engage

after engine shutdown, perform this procedure

only in a desired location (preferably, at an

authorized dealer).



Even if the transmission can be reset, we recom

mend that you visit an authorized dealer at your

earliest possible convenience. An authorized

dealer has diagnostic equipment to assess the

condition of your transmission.



If the transmission cannot be reset, authorized

dealer service is required.

1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If

not, shift the transmission to NEUTRAL.

3. Push and hold the ENGINE START/STOP

button until the engine turns off.

4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the

problem is no longer detected, the

transmission will return to normal operation.

AutoStick

AutoStick is a driver-interactive transmission

feature providing manual shift control, giving you

more control of the vehicle. AutoStick allows you to

maximize engine braking, eliminate undesirable

upshifts and downshifts, and improve overall

vehicle performance. This feature can also provide

you with more control during passing, city driving,

cold slippery conditions, mountain driving, trailer

towing, and many other situations.
Operation
To activate AutoStick mode, move the gear

selector into the MANUAL (M) position (beside the

DRIVE position). The current transmission gear will

be displayed in the instrument cluster. In AutoStick

mode, you can use the gear selector (in the

MANUAL position) to manually shift the

transmission. Tapping the gear selector forward (-)

while in the MANUAL (M) position will downshift the

transmission to the next lower gear. Tapping the

selector rearward (+) will command an upshift.
In AutoStick mode, the transmission will shift up or

down when (+/-) is manually selected by the driver,

unless an engine lugging or overspeed condition

would result.

It will remain in the selected gear until another

upshift or downshift is chosen, except as described

below:



The transmission will automatically downshift

as the vehicle slows (to prevent engine lugging)

and will display the current gear.



The transmission will automatically downshift to

FIRST gear when coming to a stop. After a stop,

the driver should manually upshift (+) the trans

mission as the vehicle is accelerated.



You can start out, from a stop, in FIRST or

SECOND gear (or THIRD gear, in 4L range).

Tapping (+) (at a stop) will allow starting in

SECOND gear. Starting out in SECOND or THIRD

gear can be helpful in snowy or icy conditions.



If a requested downshift would cause the

engine to overspeed, that shift will not occur.



The system will ignore attempts to upshift at too

low of a vehicle speed.



Holding the gear selector in the (-) position will

downshift the transmission to the lowest gear

possible at the current speed.



Transmission shifting will be more noticeable

when AutoStick is enabled.



The system may revert to automatic shift mode

if a fault or overheat condition is detected.

NOTE:

When Hill Descent Control is enabled, AutoStick is

not active.
To disengage AutoStick mode, return the gear

selector to the DRIVE position. You can shift in or

out of the AutoStick position at any time without

taking your foot off the accelerator pedal.

Four-Wheel Drive Gear Selector

The transfer case provides four positions:



2H (Two-Wheel Drive High Range)



4H (Four-Wheel Drive High Range)



N (Neutral)



4L (Four-Wheel Drive Low Range)

For additional information on the appropriate use

of each transfer case position, see the information

below:
2H
Two-Wheel Drive High Range — This range is for

normal street and highway driving on dry, hard

surfaced roads.

4H
Four-Wheel Drive High Range — This range

maximizes torque to the front driveshaft, forcing

the front and rear wheels to rotate at the same

speed. This range provides additional traction for

loose, slippery road surfaces only.
N (Neutral)

N (Neutral) — This range disengages both the front

and rear driveshafts from the powertrain. To be

used for flat towing behind another vehicle.
See Recreational Towing for further information

page 217.

WARNING!

Do not downshift for additional engine braking

on a slippery surface. The drive wheels could

lose their grip and the vehicle could skid,

causing a collision or personal injury.

WARNING!

Failure to engage a transfer case position

completely can cause transfer case damage or

loss of power and vehicle control. You could have

a collision. Do not drive the vehicle unless the

transfer case is fully engaged.

WARNING!

You or others could be injured or killed if you

leave the vehicle unattended with the transfer

case in the N (Neutral) position without first fully

engaging the parking brake. The transfer case N

(Neutral) position disengages both the front and

rear driveshafts from the powertrain, and will

allow the vehicle to roll, even if the automatic

transmission is in PARK (or manual transmission

is in gear). The parking brake should always be

applied when the driver is not in the vehicle.

170

STARTING AND OPERATING

4L
Four-Wheel Drive Low Range — This range provides

low speed four-wheel drive. It maximizes torque to

the front driveshaft, forcing the front and rear

wheels to rotate at the same speed. This range

provides additional traction and maximum pulling

power for loose, slippery road surfaces only. Do not

exceed 25 mph (40 km/h).
The transfer case is intended to be driven in the 2H

position for normal street and highway conditions,

such as hard-surfaced roads.
In the event that additional traction is required, the

transfer case 4H and 4L positions can be used to

lock the front and rear driveshafts together, forcing

the front and rear wheels to rotate at the same

speed. The 4H and 4L positions are intended for

loose, slippery road surfaces only and not intended

for normal driving. Driving in the 4H and 4L

positions on hard-surfaced roads will cause

increased tire wear and damage to the driveline

components. For further information on shifting

into 4H or 4L

page 170.

The instrument cluster alerts the driver that the

vehicle is in four-wheel drive, and the front and

rear driveshafts are locked together. The light will

illuminate when the transfer case is shifted into

the 4H position.

When operating your vehicle in 4L, the engine

speed will be approximately three times (four times

for Rubicon models) that of the 2H or 4H positions

at a given road speed. Take care not to overspeed

the engine.
Proper operation of four-wheel drive vehicles

depends on tires of equal size, type, and

circumference on each wheel. Any difference will

adversely affect shifting and cause damage to the

transfer case.
Because four-wheel drive provides improved

traction, there is a tendency to exceed safe turning

and stopping speeds. Do not go faster than road

conditions permit.

Shifting Procedures

2H TO 4H OR 4H TO 2H

Shifting between 2H and 4H can be made with the

vehicle stopped or in motion. The preferred shifting

speed would be 0 to 45 mph (72 km/h). With the

vehicle in motion, the transfer case will engage/

disengage faster if you momentarily release the

accelerator pedal after completing the shift. Do not

accelerate while shifting the transfer case. Apply a

constant force when shifting the transfer case

lever.

NOTE:



Do not attempt to make a shift while only the

front or rear wheels are spinning. 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.



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 temperatures.



Shifting effort will increase with speed, this is

normal.

During cold weather, you may experience

increased effort in shifting until the transfer case

fluid warms up. This is normal.

4H TO 4L OR 4L TO 4H

With the vehicle rolling at 1 to 3 mph (2 to 5 km/h),

shift an automatic transmission into NEUTRAL (N),

or press the clutch pedal on a manual

transmission. While the vehicle is coasting at

1 to 3 mph (2 to 5 km/h), shift the transfer case

lever firmly to the desired position. Do not pause

with the transfer case in N (Neutral). Once the shift

is completed, place the automatic transmission

into DRIVE or release the clutch pedal on a manual

transmission.
