Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for this purpose, following equipment
manufacturer ’s instructions. Use of safety chains is man-
datory. 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 regarding 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
mode, not the ACC mode.
If the key fob is unavailable or the vehicle’s battery is
discharged, refer to ”Manual Park Release” or “Gear Selector
Override” in this section for instructions on shifting the
automatic transmission out of PARK for towing.
CAUTION!
•Do not use sling type equipment when towing.
Vehicle damage may occur.
• When securing the vehicle to a flat bed truck, do not
attach to front or rear suspension components. Dam-
age to your vehicle may result from improper towing.
Two-Wheel Drive Models
The manufacturer recommends towing your vehicle with
all four wheels OFFthe ground using a flatbed.
If flatbed equipment is not available, and the transmission
is operable, this vehicle may be towed (with rear wheels on
the ground) under the following conditions:
• The transmission must be in NEUTRAL.
• The towing speed must not exceed 30 mph (48 km/h).
• The towing distance must not exceed 15 miles (24 km)
for 6-speed transmission, or 30 miles (48 km) for 8-speed
transmission.
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) for 6-speed transmission, or 30 miles (48 km)
for 8-speed transmission, tow with the rear wheels OFFthe
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.
