CAUTION!
Damage to the transmission may occur if the trans-
mission is shifted into PARK with the transfer case in
NEUTRAL and the engine running. With the transfer
case in NEUTRAL ensure, that the engine is OFF
prior to shifting the transmission into PARK.
Returning to Normal Operation Ð Electronic Shift

start the engine.4. Depress the brake pedal.
5. Shift automatic transmission to NEUTRAL or depress
clutch on manual transmission.
6. Using the point of a ballpoint pen or similar object,
depress the recessed transfer case Neutral (N) button for
one second.
7. After the Neutral indicator light turns off, release the
Neutral (N) button.
8. After the Neutral (N) button has been released, the
transfer case will shift to the position identified by the

TRAL from the 4AUTO (if equipped) position.
STARTING AND OPERATING 411

NOTE:Steps 1 through 5 are requirements that must be
met prior to depressing the transfer case Neutral (N)
button, and must continue to be met until one second
elapses and the shift has been completed. If any of these
requirements (with the exception of step 3 - key ON) are
not met prior to depressing the Neutral (N) button, or are
no longer met during the one second time, then all of the
mode position indicator lights will flash continuously
until all requirements are met, or until the Neutral (N)
button is released.
NOTE:The ignition key must be ON for a transfer case
shift to take place and for the position indicator lights to
be operable. If the key is not ON, the shift will not take
place and no position indicator lights will be on or
flashing.NOTE:Flashing Neutral position indicator light indi-
cates that shift requirements have not been met.
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
despite the transmission position. The parking brake
should always be applied when the driver is not in
the vehicle.
412 STARTING AND OPERATING

7. Check for leaks. Release parking brake.
To prevent dirt and water from entering the transmission
after checking or replenishing fluid, make certain that the
dipstick cap is properly reseated. It is normal for the
dipstick cap to spring back slightly from its fully seated
position, as long as its seal remains engaged in the
dipstick tube.
Automatic Transmission Fluid and Filter Change
Follow the Maintenance Schedule for recommended
transmission fluid and filter change intervals.
NOTE:If the transmission is disassembled for any
reason, the fluid and filter(s) should be changed.
It is important that proper lubricant is used in the
transmission. For the correct Fluid type, refer to ªFluids,
Lubricants and Genuine Partsº in this Section.
Special Additives
Automatic Transmission Fluid (ATF) is an engineered
product and its performance may be impaired by supple-
mental additives. Therefore, do not add any fluid addi-
tives to the transmission. The only exception to this
policy is the use of special dyes to aid in detecting fluid
leaks. In addition, avoid using transmission sealers as
they may adversely affect seals.
Front and Rear Wheel Bearings
Front Wheel Bearings
Front wheel bearings for all vehicles are sealed-for-life.
They do not require greasing or seal replacement. In
some instances, these bearings will ªpurgeº excess grease
and the bearing will look slightly wet. This is normal.
Periodic inspection for excess play is recommended.

²Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
²Under no circumstances should oil change intervals
exceed 6,000 miles (10,000 km) or 6 months, whichever
comes first.
Your dealer will reset the oil change indicator message
after completing the scheduled oil change. If this sched-
uled oil change is performed by someone other than your
dealer the message can be reset by referring to the steps
described under ªOdometer/Trip Odometerº under ªIn-
strument Cluster Descriptionº in Section 4 of this
manual.
At Each Stop for Fuel
²Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level whilethe vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
²Check the windshield washer solvent and add if
required.
Once a Month
²Check tire pressure and look for unusual wear or
damage.
²Inspect the battery and clean and tighten the terminals
as required.
²Check the fluid levels of coolant reservoir, brake
master cylinder, power steering and transmission and
add as needed.
²Check all lights and other electrical items for correct
operation.
