Towing Without The Ignition Key
Fob
Special care must be taken when the vehicle is
towed with the ignition in the LOCK/OFF posi-
tion. The only approved method of towing with-
out the ignition key is with a flatbed truck.
Proper towing equipment is necessary to pre-
vent damage to the vehicle.
Four-Wheel Drive VehiclesThe manufacturer recommends towing with all
wheelsOFFthe 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, the vehicle may be
towed (in the forward direction, with ALL
wheels 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 instructions.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 War-
ranty.
