STARTING AND OPERATING197
Shifting Into Transfer Case N (NEUTRAL)
Use the following procedure to prepare your
vehicle for recreational towing:

1. Bring the vehicle to a complete stop on level
ground, with the engine running.

2. Press and hold the brake pedal.
3. Shift the transmission into NEUTRAL. 4. If vehicle is equipped with Quadra-Lift air
suspension, ensure the vehicle is set to
Normal Ride Height with the Auto Entry/Exit
setting deselected.
NOTE:
Steps 1 through 4 are requirements that
must be met before pushing the N
(NEUTRAL) button, and must continue to be
met until the shift has been completed. If
any of these requirements are not met
before pushing the N (NEUTRAL) button or
are no longer met during the shift, then the
N (NEUTRAL) indicator light will flash contin -
uously until all requirements are met or until
the N (NEUTRAL) button is released.
The ignition must be in the ON/RUN position
for a shift to take place and for the position
indicator lights to be operable. If the ignition
is not in the ON/RUN position, the shift will
not take place and no position indicator
lights will be on or flashing.
A flashing N (NEUTRAL) position indicator
light indicates that shift requirements have
not been met.
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).
Tow only in a forward direction. Towing this
vehicle backwards can cause severe damage
to the transfer case.
The transmission must be in PARK for recre -
ational towing.
Before recreational towing, perform the proce -
dure outlined under “Shifting into N
(NEUTRAL)” to be certain that the transfer
case is fully in N (NEUTRAL). Otherwise,
internal damage will result.
Towing this vehicle in violation of the above
requirements can cause severe transmission
and/or transfer case damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.
Do not use a bumper-mounted clamp-on tow
bar on your vehicle. The bumper face bar will
be damaged.
WARNING!
You or others could be injured or killed if you
leave the vehicle unattended with the transfer
case in the N (NEUTRAL) position without first
fully engaging the Electric Park Brake. The
transfer case N (NEUTRAL) position disengages
both the front and rear driveshafts from the
powertrain and will allow the vehicle to roll, even
if the transmission is in PARK. The Electric Park
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 N (NEUTRAL)
before recreational towing to prevent damage to
internal parts.

198STARTING AND OPERATING
If the vehicle is equipped with Quadra-Lift
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.
Engaging/disengaging of the Electric Park
Brake requires the ignition to be in the ON/
RUN position.
If shift conditions/interlocks are not met, a
“4WD Shift Canceled” or a “4WD Shift
Aborted/ Retry Shift” message will be
displayed on the instrument cluster. To reat -
tempt shift, put the transmission in
NEUTRAL (N) and push and hold the 4WD
LOW button.
If shift conditions/interlocks are not met, a
“To Complete 4WD Shift Put Transmission
In Neutral” or a “To Complete 4WD Shift
Speed Must Be Below 3 MPH” or a “To
Complete 4WD Shift Allow Engine To Return
To Idle” message will flash from the instru -
ment cluster display Ú page 98.
5. Using a ballpoint pen or similar object, push and hold the recessed transfer case N
(NEUTRAL) button (located by the selector
switch) for more than four seconds. The light
behind the N symbol will blink, indicating shift in progress. The light will stop blinking (stay on
solid) when the shift to N (NEUTRAL) is
complete. A “Four Wheel Drive System In
Neutral” message will appear in the
instrument cluster.

N (NEUTRAL) Button

6. After the shift is complete and the N (NEUTRAL) light stays on, release the N
(NEUTRAL) button.
7. Shift the transmission into REVERSE or DRIVE.
8. Release the brake pedal for five seconds and ensure that there is no vehicle movement.
9. Press and hold the brake pedal. Shift the transmission back into NEUTRAL.
10. Apply the Electric Park Brake. 11. With the transmission and transfer case in N
(NEUTRAL), push and hold the ENGINE START/
STOP button until the engine turns off. Ensure
vehicle is in RUN position with the engine off.
12. Place the transmission gear selector in PARK. Release the brake pedal.
13. Attach the vehicle to the tow vehicle using a suitable tow bar.
14. Release the Electric Park Brake. Ensure vehicle is in RUN position with the engine off.
15. Push the ENGINE START/STOP button twice (without pressing the brake pedal), to turn the
ignition to the OFF position.
Shifting Out Of Transfer Case N (NEUTRAL)
Use the following procedure to prepare your
vehicle for normal use:

1. Bring the vehicle to a complete stop, leaving it connected to the tow vehicle.

2. Apply the Electric Park Brake.
3. Start the engine or for 4xe vehicles ensure the vehicle is in Ready to Drive mode, the READY
indicator will appear in the instrument cluster
display.

STARTING AND OPERATING201
Standing Water
Avoid driving in standing water deeper than
24 inches (61 cm) with air suspension or
21 inches (53 cm) without air suspension, and
reduce speed appropriately to minimize wave
effects. Maximum speed is 5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your
vehicle fluids and lubricants (engine oil,
transmission oil, axle, transfer case) to ensure the
fluids have not been contaminated. Contaminated
fluid (milky, foamy in appearance) should be
flushed/changed as soon as possible to prevent
component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for
additional control at slower speeds, shift the
transmission to a low gear and shift the transfer
case to 4WD LOW if necessary Ú page 131. Only
shift into a lower gear to maintain forward motion.
Over-revving the engine can spin the wheels and
traction will be lost.
Avoid abrupt downshifts on icy or slippery roads,
because engine braking may cause skidding and
loss of control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission
to a lower gear and shift the transfer case to 4WD
LOW. Use FIRST gear and 4WD LOW for very steep
hills.
If you stall or begin to lose forward motion while
climbing a steep hill, allow your vehicle to come to
a stop and immediately apply the brakes. Restart
the engine, and shift into REVERSE (R). Back slowly
down the hill, allowing the compression braking of
the engine to help regulate your speed. If the
brakes are required to control vehicle speed, apply
them lightly and avoid locking or skidding the tires. Remember, never drive diagonally across a hill.
Always drive straight up or down.
If the wheels start to slip as you approach the crest
of a hill, ease off the accelerator and maintain
forward motion by turning the front wheels slowly.
This may provide a fresh “bite” into the surface and
will usually provide traction to complete the climb.
Traction Downhill
When descending mountains or hills, use Hill
Descent Control or Selec-Speed Control to avoid
repeated heavy braking.
If not equipped with Hill Descent Control or
Selec-Speed Control use the following procedure:
Shift the transmission into a low gear, and the
transfer case into 4WD LOW range. Let the vehicle
go slowly down the hill with all four wheels turning
against engine compression drag. This will permit
you to control the vehicle speed and direction.
When descending mountains or hills, repeated
braking can cause brake fade with loss of braking
control. Avoid repeated heavy braking by
downshifting the transmission whenever possible.
WARNING!
If the engine stalls, you lose forward motion, or
cannot make it to the top of a steep hill or grade,
never attempt to turn around. To do so may
result in tipping and rolling the vehicle. Always
back carefully straight down a hill in REVERSE
gear. Never back down a hill in NEUTRAL using
only the brake.

202STARTING AND OPERATING
After Driving Off-Road
Off-road operation puts more stress on your
vehicle than does most on-road driving. After going
off-road, it is always a good idea to check for
damage. That way you can get any problems taken
care of right away and have your vehicle ready
when you need it.
Completely inspect the underbody of your
vehicle. Check tires, body structure, steering,
suspension, and exhaust system for damage.
Inspect the radiator for mud and debris and
clean as required.
Check threaded fasteners for looseness, partic -
ularly on the chassis, drivetrain components,
steering, and suspension. Retighten them, if
required, and torque to the values specified in
the Service Manual.
Check for accumulations of plants or brush.
These things could be a fire hazard. They might
hide damage to fuel lines, brake hoses, axle
pinion seals, and propeller shafts.
After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan,
brake rotors, wheels, brake linings, and axle
yokes inspected and cleaned as soon as
possible.
If you experience unusual vibration after driving
in mud, slush or similar conditions, check the
wheels for impacted material. Impacted mate -
rial can cause a wheel imbalance and freeing
the wheels of it will correct the situation.
WARNING!
Abrasive material in any part of the brakes may
cause excessive wear or unpredictable braking.
You might not have full braking power when you
need it to prevent a collision. If you have been
operating your vehicle in dirty conditions, get
your brakes checked and cleaned as necessary.
