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 allowed
ONLY if the rear wheels are OFF the 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. 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.

STARTING AND OPERATING 433
Shifting Into NEUTRAL (N)
Use the following procedure to prepare your vehicle for
recreational towing.
1. Bring the vehicle to a complete stop on level ground, withthe engine running. Firmly apply the parking brake.
2. Shift the transmission to NEUTRAL. NOTE:
If vehicle is equipped with air suspension, ensure the vehicle
is set to Normal Ride Height.
3. Press and hold the brake pedal.
4. Shift the transfer case into NEUTRAL:
•With manual shift transfer case, shift the transfer caselever into NEUTRAL (N)
•With electronic shift transfer case, push and hold the transfer case NEUTRAL (N) button. Some models 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
transfer case control knob. The NEUTRAL (N) indi -
cator 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
NEUTRAL (N) button.
5. Release the parking brake.
6. Shift the transmission into REVERSE.
WARNING!
You or others could be injured or killed if you leave the
vehicle unattended with the transfer case in the
NEUTRAL (N) position without first fully engaging the
parking brake. The transfer case NEUTRAL (N) position
disengages both the front and rear driveshafts from the
powertrain, and will allow the vehicle to roll, even if the
automatic transmission is in PARK. The parking brake
should always be applied when the driver is not in the
vehicle.
CAUTION!
It is necessary to follow these steps to be certain that the
transfer case is fully in NEUTRAL (N) before
recreational towing to prevent damage to internal parts.

434 STARTING AND OPERATING
7. Release the brake pedal for five seconds and ensure thatthere is no vehicle movement.
8. Repeat steps 6 and 7 with automatic transmission in DRIVE.
9. Shift the transmission to NEUTRAL. Firmly apply the parking brake. Turn OFF the engine. For vehicles with
Keyless Enter-N-Go, push and hold the ENGINE
START/STOP button until the engine shuts off.
10. Shift the transmission into PARK. On 8-speed transmis -
sions the shifter will automatically select PARK when the
engine is turned off.
11. Turn the ignition to the OFF mode, then cycle the ignition to the RUN mode and back to the OFF mode. Remove the
key fob from the ignition.
12. Attach the vehicle to the tow vehicle using a suitable tow bar.
13. Release the parking brake. NOTE:
With electronic shift transfer case:
• Steps 2 through 3 are requirements that must be met before
pushing the NEUTRAL (N) button, and must continue to
be met until the shift has been completed. If any of these
requirements are not met before pushing the NEUTRAL
(N) button or are no longer met during 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 oper -
able. 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.
