10-98 Vehicle Care
Four-Wheel Drive Vehicles with a
Two Speed Automatic
Transfer Case
Use the following procedure to dolly
tow a four-wheel drive vehicle from
the rear:
1. Attach the dolly to the towvehicle following the dolly
manufacturer's instructions.
2. Drive the rear wheels onto the dolly.
3. Firmly set the parking brake. See Parking Brake on
page 9‑53.
4. Put the transmission in P (Park).
5. Secure the vehicle to the dolly following the manufacturer's
instructions.
6. Use an adequate clamping device designed for towing to
ensure that the front wheels are
locked into the straight position.{WARNING
Shifting a four-wheel-drive
vehicle's transfer case into
N (Neutral) can cause the vehicle
to roll even if the transmission is
in P (Park). The driver or others
could be injured. Make sure the
parking brake is firmly set before
the transfer case is shifted to
N (Neutral).
7. Shift the transfer case to N (Neutral). See “Shifting into
N (Neutral)” under“Four-Wheel
Drive”.
8. Turn the ignition to LOCK/OFF.
After towing, see “Shifting Out of
N (Neutral)” under“Four-Wheel
Drive”.
Appearance Care
Exterior Care
Silicone grease on weatherstrips will
make them last longer, seal better,
and not stick or squeak. Apply
silicone grease with a clean cloth.
During very cold, damp weather
frequent application may be
required. See Recommended Fluids
and Lubricants on page 11‑6.
Washing the Vehicle
The best way to preserve the
vehicle's finish is to keep it clean by
washing it often.
Notice: Certain cleaners contain
chemicals that can damage the
emblems or nameplates on the
vehicle. Check the cleaning
product label. If it states that it
should not be used on plastic
parts, do not use it on the vehicle
or damage may occur and it
would not be covered by the
warranty.

Service and Maintenance 11-5
Check to be sure vent hose is
unobstructed, clear, and free of
debris. During any maintenance,
if a power washer is used to
clean mud and dirt from the
underbody, care should be taken
to not directly spray the transfer
case output seals. High pressure
water can overcome the seals
and contaminate the transfer
case fluid. Contaminated fluid
will decrease the life of the
transfer case and should
be replaced.
.Evaporative control system
inspection. Check all fuel and
vapor lines and hoses for proper
hook‐up, routing, and condition.
Check that the purge valve,
if the vehicle has one, works
properly. Replace as needed.
An Emission Control Service.
The U.S. Environmental
Protection Agency or the
California Air Resources Board
has determined that the failure
to perform this maintenance item
will not nullify the emissionwarranty or limit recall liability
prior to the completion of the
vehicle's useful life. We,
however, urge that all
recommended maintenance
services be performed at the
indicated intervals and the
maintenance be recorded.

any maintenance, if a power
washer is used to clean mud
and dirt from the underbody,
care should be taken to not
directly spray the transfer case
output seals. High pressure water can
overcome the seals and
contaminate the transfer case
fluid. Contaminated fluid will
decrease the life of the transfer
case and should be replaced.
