33 mph (53 km/h). Once the vehicle speed goes below15 mph (24 km/h) the vehicle height will begin to lower. If
the vehicle speed remains between 15 mph (24 km/h) and
25 mph (40 km/h) for greater than 60 seconds, or the
vehicle speed exceeds 25 mph (40 km/h) the Entry/Exitchange will be cancelled. To return to Normal Height
Mode, push the height selector switch up once while in
Entry/Exit or drive the vehicle over 15 mph (24 km/h).
Entry/Exit mode may not be available due to vehicle
payload, an instrument cluster message will be displayed
when this occurs. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for further
information.
NOTE:
Entry/Exit mode may be achieved using your key fob for
easier entry/loading. Refer to “Keys” in “Getting To Know
Your Vehicle” for further information. The system requires that the ignition be in the ON/RUN
position or the engine running for all user requested
changes. When lowering the vehicle all of the doors, must be
closed. If a door is opened at any time while the vehicle is
lowering the change will not be completed until the open
door(s) is closed.
This system uses a lifting and lowering pattern which keeps
the headlights from incorrectly shining into oncoming
traffic. When raising the vehicle, the rear of the vehicle will
move up first and then the front. When lowering the vehicle,
the front will move down first and then the rear.
After the engine is turned off, it may be noticed that the air
suspension system operates briefly, this is normal. The
system is correcting the position of the vehicle to ensure a
proper appearance.
To assist with changing a spare tire, the air suspension
system has a feature which allows the automatic leveling to
be disabled. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for further infor
-
mation.
CAUTION!
When in ENTRY/EXIT setting, be aware of your
surroundings, you may not have the clearance required
for certain areas and vehicle damage may occur.

•Entry/Exit Mode (Lowers the vehicle approximately
3 inches (73 mm)) – This position lowers the vehicle for
easier passenger entry and exit as well as lowering the
rear of the vehicle for easier loading and unloading of
cargo. To enter Entry/Exit Mode, push the height
selector switch down twice from the NRH while the
vehicle speed is below 33 mph (53 km/h). Once the
vehicle speed goes below 15 mph (24 km/h) the vehicle
height will begin to lower. If the vehicle speed remains
between 15 mph (24 km/h) and 25 mph (40 km/h) for
greater than 60 seconds, or the vehicle speed exceeds
25 mph (40 km/h) the Entry/Exit change will be

350 STARTING AND OPERATING
Distance Setting 1 Bar (Short)
To increase the distance setting, push the Distance Setting —
Increase button and release. Each time the button is pushed,
the distance setting increases by one bar (longer).
To decrease the distance setting, push the Distance Setting —
Decrease button and release. Each time the button is pushed,
the distance setting decreases by one bar (shorter).

If there is no vehicle ahead, the vehicle will maintain the set
speed. If a slower moving vehicle is detected in the same lane,
the instrument cluster displays the “Sensed Vehicle Indicator”
icon, and the system adjusts vehicle speed automatically to
maintain the distance setting, regardless of the set speed.
The vehicle will then maintain the set distance until:
• The vehicle ahead accelerates to a speed above the set
speed.
• The vehicle ahead moves out of your lane or view of the sensor.
• The distance setting is changed.
• The system disengages. (Refer to the information on ACC Activation).
The maximum braking applied by ACC is limited; however,
the driver can always apply the brakes manually, if neces -
sary.
NOTE:
The brake lights will illuminate whenever the ACC system
applies the brakes.
A Proximity Warning will alert the driver if ACC predicts
that its maximum braking level is not sufficient to maintain
the set distance. If this occurs, a visual alert “BRAKE” will
flash in the instrument cluster display and a chime will
sound while ACC continues to apply its maximum braking
capacity.

Towing Requirements — Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-pin
wiring harness. Use a factory approved trailer harness and
connector.
NOTE:
Do not cut or splice wiring into the vehicle’s wiring harness.
The electrical connections are all complete to the vehicle but
you must mate the harness to a trailer connector. Refer to the
following illustrations.
NOTE:
• Disconnect trailer wiring connector from the vehiclebefore launching a boat (or any other device plugged into
vehicle’s electrical connect) into water.
• Be sure to reconnect once clear from water area. Four-Pin Connector
1 — Female Pins
2 — Male Pin

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
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. Shifting Out Of NEUTRAL (N)
Use the following procedure to prepare your vehicle for
normal usage:
1. Bring the vehicle to a complete stop, leaving it connected
to the tow vehicle.
2. Press and hold the brake pedal.
3. Start the engine. Apply the parking brake. Shift the trans -
mission into NEUTRAL.
4. Using a ballpoint pen or similar object, push and hold the recessed transfer case NEUTRAL (N) button (at the center
of the transfer case switches).
5. When the NEUTRAL (N) indicator light turns off, release the NEUTRAL (N) button.
6. Turn the engine OFF. The transmission will automatically select PARK when the engine is turned off.
7. Release the brake pedal.
8. Disconnect vehicle from the tow vehicle.
9. Press and hold the brake pedal.

10. Start the engine.
11. Release the parking brake.
12. Shift the transmission into DRIVE, release the brakepedal, and check that the vehicle operates normally.
NOTE:
• Steps 3 and 4 are requirements that must be met before pushing the button to shift out of NEUTRAL (N), and must
continue to be met until the shift has been completed. If
any of these requirements are not met before pushing the
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 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.DRIVING TIPS
Driving On Slippery Surfaces
Acceleration
Rapid acceleration on snow covered, wet, or other slippery
surfaces may cause the driving wheels to pull erratically to
the right or left. This phenomenon occurs when there is a
difference in the surface traction under the rear (driving)
wheels.
Driving Through Water
Driving through water more than a few inches/centimeters
deep will require extra caution to ensure safety and prevent
damage to your vehicle.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the rear
wheels. You could lose control of the vehicle and
possibly have a collision. Accelerate slowly and carefully
whenever there is likely to be poor traction (ice, snow,
wet, mud, loose sand, etc.).5
