Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for the purpose, following equip-
ment manufacturer ’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing device to main structural members of the vehicle, not to bumpers
or associated brackets. State and local laws applying to
vehicles under tow must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
position, not the ACC position.

WHAT TO DO IN EMERGENCIES 567

If the transmission is not operable, or the vehicle must be
towed faster than 30 mph (48 km/h) or farther than
15 miles (24 km), tow with the rear wheelsOFFthe
ground. Acceptable methods are to tow the vehicle on a
flatbed, or with the front wheels raised and the rear
wheels on a towing dolly, or (when using a suitable
steering wheel stabilizer to hold the front wheels in the
straight position) with the rear wheels raised and the
front wheels on the ground.
Four-Wheel Drive Models
The manufacturer recommends towing with all wheels
OFF the ground. Acceptable methods are to tow the
vehicle on a flatbed or with one end of vehicle raised and
the opposite end on a towing dolly.
If flatbed equipment is not available, and the transfer
case is operable, vehicles with a two-speed transfer case
may be towed (in the forward direction, with ALLwheels
on the ground), IFthe transfer case is in NEUTRAL and the transmission is in
PARK. Refer to “Recreational
Towing” in “Starting And Operating” for detailed in-
structions.
Vehicles equipped with a single-speed transfer case have
no NEUTRAL position, and therefore mustbe towed
with all four wheels OFFthe ground.
CAUTION!
•Front or rear wheel lifts should not be used.
Internal damage to the transmission or transfer
case will occur if a front or rear wheel lift is used
when towing.
•Failure to follow these towing methods can cause
severe damage to the transmission and/or transfer
case. Such damage is not covered by the New
Vehicle Limited Warranty.

The rear axle oil level needs to be between 1/8 in (3 mm)
below the bottom of the fill hole and the bottom of the fill
hole.
The rear axle fill and drain plugs should be tightened to
22 to 29 ft lbs (30 to 40 N·m) on axles with aluminum
housings. The rear axle fill and drain plugs should be
tightened to 22 to 52 ft lbs (30 to 70 N·m) on axles with
cast iron housings.

Inspect the transfer case for fluid leaks. If a fluid leak is
found, the transfer case fluid level can be checked by
removing the filler plug located on the back side of the
transfer case. The fluid level should be at the bottom edge
of the filler plug hole when the vehicle is in a level
position.
