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 vehicle’s battery is discharged, refer to “Shift Lever
Override” in “What to Do in Emergencies” for instruc-
tions on shifting the automatic transmission out of the
PARK position for towing.
CAUTION!
Do not attempt to use sling type equipment when
towing. When securing the vehicle to a flat bed truck,
do not attach to front or rear suspension components.
Damage to your vehicle may result from improper
towing.
Towing Without The Ignition Key Fob
Special care must be taken when the vehicle is towed
with the ignition in the LOCK/OFF position. The only
approved method of towing without the ignition key is
with a flatbed truck. Proper towing equipment is neces-
sary to prevent damage to the vehicle.
Two-Wheel Drive Models
The manufacturer recommends towing your vehicle with
all four wheelsOFFthe ground using a flatbed.
If flatbed equipment is not available, and the transmis-
sion is operable, the vehicle may be towed (with rear
wheels on the ground) with the transmission in NEU-
TRAL. Speed must not exceed 30 mph (48 km/h) and the
distance must not exceed 15 miles (24 km).
CAUTION!
Towing faster than 30 mph (48 km/h) or farther than
15 miles (24 km) with rear wheels on the ground can
cause severe damage to the transmission. Such dam-
age is not covered by the New Vehicle Limited
Warranty.
568 WHAT TO DO IN EMERGENCIES

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.
