426 STARTING AND OPERATING
NOTE:
• Steps 2 and 3 are requirements that must be met beforepushing 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

NOTE:
When the lever is locked in the released position the access
cover cannot be reinstalled.
4. Behind the Manual Park Release access cover is theorange tether strap. Pull the tether strap out as far as it
will go, then release it. The tether and lever will remain
outside of the trim panel and the transmission should
now be in NEUTRAL, allowing the vehicle to be moved.
To Reset The Manual Park Release:
1. Apply firm pressure to the brake pedal while seated in the driver’s seat.
2. Pull the tether strap out again, then release it.
3. Allow the tether to retract with the lever back to its orig -
inal position.
4. Verify the transmission is in PARK.
5. Confirm that the tether has retracted fully and re-install the access cover. If the access cover cannot be reinstalled,
repeat steps 1 though 4.
6. Re-install the access cover.FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or snow, it can
often be moved using a rocking motion. Turn the steering
wheel right and left to clear the area around the front wheels.
Then shift back and forth between DRIVE (D) and REVERSE
(R), while gently pressing the accelerator. Use the least
amount of accelerator pedal pressure that will maintain the
rocking motion, without spinning the wheels or racing the
engine.
NOTE:
Shifts between DRIVE and REVERSE can only be achieved at
wheel speeds of 5 mph (8 km/h) or less. Whenever the trans -
mission remains in NEUTRAL (N) for more than two
seconds, you must press the brake pedal to engage DRIVE or
REVERSE.
NOTE:
Push the “ESC Off” switch, to place the Electronic Stability
Control (ESC) system in “Partial Off” mode, before rocking
the vehicle. Refer to “Electronic Brake Control” in “Safety”
for further information. Once the vehicle has been freed,
push the “ESC Off” switch again to restore “ESC On” mode.

478 IN CASE OF EMERGENCY
TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial towing service.
If the transmission and drivetrain are operable, disabled
vehicles may also be towed as described under “Recreational
Towing (Behind Motorhome, Etc.)” in the “Starting And
Operating” section.
NOTE:
Vehicles equipped with the Active-Level Four Corner Air
Suspension System must be placed in Transport mode,
before tying them down (from the body) on a trailer or
flatbed truck. 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.
Refer to "Active-Level Four Corner Air Suspension System
— If Equipped" in "Starting And Operating" for more infor-
mation.
WARNING!

Fast spinning tires can be dangerous. Forces generated by
excessive wheel speeds may cause damage, or even failure, of
the axle and tires. A tire could explode and injure someone.
Do not spin your vehicle's wheels faster than 30 mph (48 km/ h) or for longer than 30 seconds continuously without
stopping when you are stuck and do not let anyone near a
spinning wheel, no matter what the speed.

CAUTION!
• Racing the engine or spinning the wheels may lead to transmission overheating and failure. Allow the engine to
idle with the transmission in NEUTRAL for at least one
minute after every five rocking-motion cycles. This will
minimize overheating and reduce the risk of transmission
failure during prolonged efforts to free a stuck vehicle.
• When “rocking” a stuck vehicle by shifting between DRIVE and REVERSE, do not spin the wheels faster than
15 mph (24 km/h), or drivetrain damage may result.
• Revving the engine or spinning the wheels too fast may lead to transmission overheating and failure. It can also
damage the tires. Do not spin the wheels above 30 mph
(48 km/h) while in gear (no transmission shifting occur-
ring).

(Continued)
Two-Wheel Drive Models
The manufacturer recommends towing your vehicle with all
four wheels OFF the ground using a flatbed.
If flatbed equipment is not available, and the transmission is
operable, the vehicle may be towed (with rear wheels on the
ground) under the following conditions:
• The transmission must be in NEUTRAL.
NOTE:
Refer to “Manual Park Release” in this section for instruc -
tions on shifting the transmission to NEUTRAL when the
engine is OFF.
• The towing speed must not exceed 30 mph (48 km/h).
• The towing distance must not exceed 30 miles (48 km).
If the transmission is not operable, or the vehicle must be
towed faster than 30 mph (48 km/h) or farther than 30 miles (48 km), tow with the rear wheels OFF the ground. Accept -
able 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.
Four-Wheel Drive Models
The manufacturer recommends towing with all wheels OFF
the 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), IF the transfer case is in
NEUTRAL (N) and the transmission is in PARK.
Refer to “Recreational Towing” in “Starting And Operating”
for further information and detailed instructions. CAUTION!
Towing this vehicle in violation of the above
requirements can cause severe transmission damage.
Damage from improper towing is not covered under the
New Vehicle Limited Warranty.
CAUTION!
• Front or rear wheel lifts must not be used (if the remaining wheels are on the ground). Internal damage
to the transmission or transfer case will occur if a front
or rear wheel lift is used when towing.
