Recreational Towing — Four-Wheel Drive Models
NOTE: Both the manual shift and electronic shift transfer
cases must be shifted into NEUTRAL (N) for recreational
towing. Automatic transmissions must be shifted into
PARK for recreational towing. Manual transmissions
must be placed in gear (NOT in NEUTRAL) for recre-
ational towing. Refer to the following for the proper
transfer case NEUTRAL (N) shifting procedure for your
vehicle.
CAUTION!• DO NOT dolly tow any 4WD vehicle. Towing with
only one set of wheels on the ground (front or rear)
will cause severe transmission and/or transfer case
damage. Tow with all four wheels either ON the
ground, or OFF the ground (using a vehicle trailer). (Continued) CAUTION! (Continued)• Tow only in the forward direction. Towing this
vehicle backwards can cause severe damage to the
transfer case.
• Automatic transmissions must be placed in PARK
for recreational towing.
• Manual transmissions must be placed in gear (not
in Neutral) for recreational towing.
• Before recreational towing, perform the procedure
outlined under “Shifting Into NEUTRAL (N)” to be
certain that the transfer case is fully in NEUTRAL
(N). Otherwise, internal damage will result.
• Towing this vehicle in violation of the above re-
quirements can cause severe transmission and/or
transfer case damage. Damage from improper tow-
ing is not covered under the New Vehicle Limited
Warranty. (Continued)530 STARTING AND OPERATING
