Recreational Towing — Two-Wheel Drive Models
DO NOT flat tow this vehicle. Damage to the drivetrain
will result.
Recreational towing (for two-wheel drive models) is al-
lowedONLY if the rear wheels are OFFthe ground. This
may be accomplished using a tow dolly or vehicle trailer. If
using a tow dolly, follow this procedure:
NOTE: If vehicle is equipped with air suspension, ensure
the vehicle is set to Normal Ride Height.
1. Properly secure the dolly to the tow vehicle, following the dolly manufacturer’s instructions.
2. Drive the rear wheels onto the tow dolly.
3. Firmly apply the parking brake. Place automatic trans- mission in PARK, manual transmission in gear (not in
NEUTRAL).
4. Properly secure the rear wheels to the dolly, following the dolly manufacturer’s instructions.
5. Turn the ignition OFF and remove the key fob.
6. Install a suitable clamping device, designed for towing, to secure the front wheels in the straight position.
CAUTION!
•Towing with the rear wheels on the ground will
cause severe transmission damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.
•
Do not disconnect the driveshaft because fluid may
leak from the transmission, causing damage to internal
parts.
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 recreational
towing. Refer to the following for the proper transfer case
NEUTRAL (N) shifting procedure for your vehicle.

have a small, recessed “N” button (at the center of the
transfer case switches) that must be pushed using a
ballpoint pen or similar object. Other models have a
rectangular NEUTRAL switch, below the rotary trans-
fer case control knob. The NEUTRAL (N) indicator light will blink while the shift is in progress. The light
will stop blinking (stay on solid) when the shift to
NEUTRAL (N) is complete. After the shift is completed
and the NEUTRAL (N) light stays on, release the

the shift, the NEUTRAL (N) indicator light will flash
continuously until all requirements are met or until the
NEUTRAL (N) button is released.
• The ignition must be in the ON/RUN mode for a shift to
take place and for the position indicator lights to be
operable. If the ignition is not in the ON/RUN mode, the
shift will not take place and no position indicator lights
will be on or flashing.
• A flashing NEUTRAL (N) position indicator light indi-
cates that shift requirements have not been met. •
If the vehicle is equipped with air suspension, the engine
should be started and left running for a minimum of 60
seconds (with all the doors closed) at least once every 24
hours. This process allows the air suspension to adjust
the vehicle’s ride height to compensate for temperature
effects.

This section describes procedures for towing a disabled
vehicle using a commercial towing service. If the transmis-
sion and drivetrain are operable, disabled vehicles may
also be towed as described under “Recreational Towing” in
the “Starting And Operating” section.
NOTE: Vehicles equipped with air suspension must be
placed in Transport mode, before tying them down (from
the body) on a trailer or flatbed truck. Refer to Air
Suspension inStarting And Operating for more informa-
tion. If the vehicle cannot be placed in Transport mode (for
example, engine will not run), tie-downs must be fastened
to the axles (not to the body). Failure to follow these
instructions may cause fault codes to be set and/or cause
loss of proper tie-down tension.
626 WHAT TO DO IN EMERGENCIES

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.
