rearward into 4LO. In 4 FULL TIME, there is a neutral
stop to prevent shifting into N (Neutral) by accident.
NOTE:Pausing in transfer case N (Neutral) in vehicles
equipped with an automatic transmission may require
shutting the engine OFF to avoid gear clash while
completing the shift. If difficulty occurs, shift transmis-
sion to N (Neutral), hold foot on brake, and turn engine
OFF. Make shift to desired mode.
NOTE:Shifting into or out of 4LO 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 4LO
with the vehicle moving faster than 2 to 3 mph (3 to 5
km/h).TRAC-LOKŸ REAR AXLE Ð IF EQUIPPED
The optional Trac-LokŸ rear axle provides a constant
driving force to both rear wheels and reduces wheel spin
caused by the loss of traction at one driving wheel. If
traction differs between the two rear wheels, the differ-
ential automatically proportions the usable torque by
providing more torque to the wheel that has traction.
Trac-LokŸ is especially helpful during slippery driving
conditions. With both rear wheels on a slippery surface, a
slight application of the accelerator will supply maxi-
mum traction. When starting with only one rear wheel on
an excessively slippery surface, slight application of the
parking brake may be necessary to gain maximum trac-
tion.

TRAILER TOWING
In this section you will find information on limits to the
type of towing you can reasonably do with your vehicle.
Before towing a trailer, carefully review this information
to tow your load as efficiently and safely as possible.
To maintain warranty coverage, follow the requirements
and recommendations in this manual concerning ve-
hicles used for trailer towing.
Perform maintenance services as prescribed in the
ªMaintenance Schedulesº section. When your vehicle is
used for trailer towing, never exceed the gross axle
weight rating (GAWR) by the addition of:
²The tongue weight of the trailer.
²The weight of any other type of cargo or equipment
put in or on your vehicle.
Remember that everything put in or on the trailer adds to
the load on your vehicle.
Warranty Requirements
The manufacturer's warranty will apply to vehicles used
to tow trailers for noncommercial use, however the
following conditions must be met:
²The ªDº Overdrive range can be selected when tow-
ing. However, if frequent shifting occurs select the
ªO/D Offº function or move the shift lever to the next
lower position to eliminate excessive automatic trans-
mission shifting. This action will also reduce the
possibility of transmission overheating and provide
better engine braking. Refer to ªTransmission Shift-
ingº in this section for additional information.
²A load equalizing hitch is recommended for loaded
trailer weights above 1,000 lbs (454 kg).
264 STARTING AND OPERATING

CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
WARNING!
Connecting trailer brakes to your vehicle's hydraulic
brake lines can overload your brake system and
cause it to fail. You might not have brakes when you
need them and could have an accident.
²Whenever you pull a trailer, regardless of the trailer
size, stop lights and turn signals on the trailer are
mandatory for motoring safety.
²Follow the maintenance intervals in schedule ªBº for
changing the automatic transmission fluid and filter, if
you REGULARLY tow a trailer for more than 45
minutes of continuous operation.

CAUTION!
It is necessary to follow these steps to be certain that
the transfer case is fully in N (Neutral) before
recreational towing to prevent damage to internal
parts.
1. Depress brake pedal.
2. Shift transmission into N (Neutral).
3. Shift transfer case lever into N (Neutral).
4. Start engine.
5. Shift automatic transmission into D (Drive) or manual
transmission into any forward gear.
6. Release brake pedal and ensure that there is no vehicle
movement.7. Shut the engine OFF and place the ignition key into
the unlocked OFF position.
8. Shift automatic transmission into P (Park) or ensure
manual transmission is in any forward gear.
9. Apply parking brake.
10. Attach vehicle to the tow vehicle with tow bar.
11. Release parking brake.
CAUTION!
Transmission damage may occur if the automatic
transmission is shifted into P (Park) with the transfer
case in N (Neutral) and the engine running. With the
transfer case in N (Neutral) ensure that the engine is
OFF prior to shifting the transmission into P (Park)
(refer to steps7±8above).
268 STARTING AND OPERATING

Shifting Out Of Neutral (N)
Use the following procedure to prepare your vehicle for
normal usage.
1. Shift transmission into N (Neutral).
2. Shift transfer case lever to desired position.
3. Shift automatic transmission into D (Drive) or manual
transmission into any forward gear.
NOTE:When shifting out of transfer case N (Neutral)
on automatic transmission equipped vehicles, turning
the engine OFF may be required to avoid gear clash.WARNING!
You or others could be injured 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 move
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
CAUTION!
Do not use a bumper mounted clamp-on tow bar on
your vehicle. The bumper face bar will be damaged.

ONBOARD DIAGNOSTIC SYSTEM Ð OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the ªMalfunction Indicator Light.º It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.CAUTION!
²Prolonged driving with the ªMalfunction Indica-
tor Lightº on could cause further damage to the
emission control system. It could also affect fuel
economy and driveability. The vehicle must be
serviced before any emissions tests can be per-
formed.
²If the ªMalfunction Indicator Lightº is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur.
Immediate service is required.

WARNING!
Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter. Do
not allow petroleum base fluid to contaminate the brake
fluid as seal damage will result.
Automatic Transmission
Selection of Lubricant
It is important that the proper lubricant is used in the
transmission to assure optimum transmission perfor-
mance. Use only manufacturer's recommended transmis-
sion fluid, refer to Recommended Fluids, Lubricants, and
Genuine Parts for correct fluid type. It is important that
the transmission fluid be maintained at the prescribed
level using the recommended fluid.
CAUTION!
Using a transmission fluid other than the manufac-
turer's recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than the
manufacturer's recommended fluid will result in
more frequent fluid and filter changes. Refer to
Recommended Fluids, Lubricants, and Genuine
Parts for correct fluid type.
Fluid Level Check ± 3.7L 42RLE
This fluid level should be checked when the engine is
fully warmed up and the fluid in the transmission is
heated to its normal operating temperature. Operation of
the transmission with an improper fluid level will greatly
reduce the life of the transmission and of the fluid.
