If the shift lever is not in PARK and the ENGINE
START/STOP button is pressed once, the EVIC
(if equipped) will display a “Vehicle Not In Park”
message and the engine will remain running.
Never leave a vehicle out of the PARK position,
or it could roll.
NOTE:
If the ignition switch is left in the ACC or
RUN (engine not running) position and the
transmission is in PARK, the system will
automatically time out after 30 minutes of
inactivity and the ignition will switch to the
OFF position.
Keyless Enter-N-Go™ Functions – With
Driver’s Foot OFF The Brake Pedal/Clutch
Pedal (In PARK Or NEUTRAL Position)
The Keyless Enter-N-Go™ feature operates
similar to an ignition switch. It has four positions,
OFF, ACC, RUN and START. To change the
ignition switch positions without starting thevehicle and use the accessories follow these
steps.
•
Starting with the ignition switch in the OFF
position:
• Press the ENGINE START/STOP button
once to change the ignition switch to the ACC
position (EVIC displays “IGNITION MODE
ACCESSORY”),
• Press the ENGINE START/STOP button a
second time to change the ignition switch to
the RUN position (EVIC displays “IGNITION
MODE RUN”),
• Press the ENGINE START/STOP button a
third time to return the ignition switch to the
OFF position (EVIC displays “IGNITION
MODE OFF”).
Extreme Cold Weather (Below –20°F
Or 29°C)
To ensure reliable starting at these tempera-
tures, use of an externally powered electric
engine block heater (available from your autho-
rized dealer) is recommended.
If Engine Fails To Start
WARNING!
•
Never pour fuel or other flammable liquid
into the throttle body air inlet opening in an
attempt to start the vehicle. This could result
in flash fire causing serious personal injury.
•Do not attempt to push or tow your vehicle
to get it started. Vehicles equipped with an
automatic transmission cannot be started
this way. Unburned fuel could enter the
catalytic converter and once the engine
has started, ignite and damage the con-
verter and vehicle.
• If the vehicle has a discharged battery,
booster cables may be used to obtain a
start from a booster battery or the battery
in another vehicle. This type of start can be
dangerous if done improperly. Refer to
“Jump Starting” in “What To Do In Emer-
gencies” for further information.

•Auto – Fully automatic full time four-wheel
drive operation can be used on and off road.
Balances traction with seamless steering feel
to provide improved handling and accelera-
tion over two-wheel drive vehicles. If
equipped with air suspension, the level will
change to NRH.
•
Sand/Mud–Off road calibration for use on low
traction surfaces such as mud, sand, or wet
grass. Driveline is maximized for traction.
Some binding may be felt on less forgiving
surfaces. The electronic brake controls are set
to limit traction control management of throttle
and wheel spin. If equipped with air suspen-
sion, the level will change to Off-Road 1.
• Rock – Off-road calibration only available in
4WD Low range. The vehicle is raised (if
equipped with Air Suspension) for improved
ground clearance. Traction based tuning with
improved steer-ability for use on high traction
off-road surfaces. Activate the Hill Descent
Control for steep downhill control. Use for low
speed obstacles such as large rocks, deep ruts, etc. If equipped with air suspension, the
vehicle level will change to Off-Road 2. If the
Selec-Terrain™ switch is in ROCK mode,
and the transfer case is switched from 4WD
Low to 4WD High, the Selec-Terrain™ sys-
tem will return to AUTO.

The system requires that the engine be running
for all changes. When lowering the vehicle all of
the doors, including the liftgate, 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.
The Quadra-Lift™ air suspension system uses
a lifting and lowering pattern which keeps the
headlights from incorrectly shining into oncom-
ing 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 ap-
pearance.
To assist with changing a spare tire, the
Quadra-Lift™ air suspension system has a fea-
ture which allows the automatic leveling to be
disabled. Press and hold both the “Up” and
“Down” buttons simultaneously between 5 and
10 seconds, a message will appear in the EVIC
stating leveling has been disabled immediatelyafter both buttons have been released. Refer to
“Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for
further information. Driving the vehicle over
5 mph (8 km/h) will return the air suspension to
normal operation. Refer to “Jacking and Tire
Changing” in “What To Do In Emergencies” for
further information.
WARNING!
The air suspension system uses a high pres-
sure volume of air to operate the system. To
avoid personal injury or damage to the sys-
tem, see your authorized dealer for service.

Center (EVIC) Display Messages
When the appropriate conditions exist, a mes-
sage will appear in the EVIC display. Refer to
“Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for
further information.
An audible chime will be heard whenever a
system error has been detected.
OperationThe indicator lamps 3 through 6 will illuminate to
show the current position of the vehicle. Flash-
ing indicator lamps will show a position which
the system is working to achieve. When raising,
if multiple indicator lamps are flashing on the
“Up” button, the highest flashing indicator lamp
is the position the system is working to achieve.
When lowering, if multiple indicators are flash-
ing on the
"Up"button the lowest solid indicator
lamp is the position the system is working to
achieve.
Pressing the “UP” button once will move the
suspension one position higher from the current
position, assuming all conditions are met (i.e.
engine running, speed below threshold, etc).
The “UP” button can be pressed multiple times,
each press will raise the requested level by one
position up to a maximum position of OR2 or the
highest position allowed based on current con-
ditions (i.e. vehicle speed, etc).
243

Pressing the “DOWN” button once will move the
suspension one position lower from the current
level, assuming all conditions are met (i.e. en-
gine running, doors closed, speed below
threshold, etc). The “DOWN” button can be
pressed multiple times. Each press will lower
the requested level by one position down to a
minimum of Park Mode or the lowest position
allowed based on current conditions (i.e. ve-
hicle speed, etc.)
Automatic height changes will occur based on
vehicle speed and the current vehicle height.
The indicator lamps and EVIC messages will
operate the same for automatic changes and
user requested changes.
•Off-Road 2 (OR2) – Indicator lamps 4, 5, and
6 will be illuminated when the vehicle is in
OR2.
• Off-Road 1 (OR1) – Indicator lamps 4 and 5
will be illuminated when the vehicle is in
OR1.
• Normal Ride Height (NRH) – Indicator lamp 4
will be illuminated when the vehicle is in this
position. •
Park Mode – Indicator lamp 3 will be illumi-
nated when the vehicle is in Park Mode. If
Park Mode is requested while vehicle speed
is between 15 mph (24 km/h) and 25 mph
(40 km/h), indicator lamp 4 will remain on
solid and indicator lamp 3 will flash as the
system waits for the vehicle to reduce speed.
If vehicle speed is reduced to, and kept
below, 15 mph (24 km/h) indicator lamp 4 will
turn off and indicator lamp 3 will flash until
Park Mode is achieved at which point indica-
tor lamp 3 will go solid. If during the height
change to Park Mode, the vehicle speed
exceeds 15 mph (24 km/h), the height
change will be paused until the vehicle speed
either goes below 15 mph (24 km/h) and the
height change continues to Park Mode, or
exceeds 25 mph (40 km/h) and the vehicle
height will return to NRH. Park Mode may be
selected while the vehicle is not moving
provided that the engine is still running and
all doors remain closed.ON-ROAD DRIVING TIPS
Utility vehicles have higher ground clearance
and a narrower track to make them capable of
performing in a wide variety of off-road applica-
tions. Specific design characteristics give them
a higher center of gravity than ordinary cars.
An advantage of the higher ground clearance is
a better view of the road, allowing you to
anticipate problems. They are not designed for
cornering at the same speeds as conventional
two-wheel drive vehicles any more than low-
slung sports cars are designed to perform sat-
isfactorily in off-road conditions. If at all pos-
sible, avoid sharp turns or abrupt maneuvers.
As with other vehicles of this type, failure to
operate this vehicle correctly may result in loss
of control or vehicle rollover.

WARNING!
Continued operation with reduced power
steering assist could pose a safety risk to
yourself and others. Service should be ob-
tained as soon as possible.
CAUTION!
Prolonged operation of the steering system
at the end of the steering wheel travel will
increase the steering fluid temperature and it
should be avoided when possible. Damage
to the power steering pump may occur.
3.0L Diesel EngineYour vehicle is equipped with an electro-
hydraulic power steering system that will give
you good vehicle response and increased ease
of maneuverability in tight spaces. The system
will vary its assist to provide light efforts while
parking and good feel while driving. If theelectro-hydraulic power steering system experi-
ences a fault that prevents it from providing
power steering assist, then the system will
provide mechanical steering capability.
CAUTION!
Extreme steering maneuvers may cause the
electrically driven pump to reduce or stop
power steering assistance in order to prevent
damage to the system. Normal operation will
resume once the system is allowed to cool.
If the “SERVICE POWER STEER-
ING SYSTEM” message and a
flashing icon are displayed on the
EVIC screen, it indicates that the
vehicle needs to be taken to the
dealer for service. It is likely the
vehicle has lost power steering assistance. Re-
fer to “Electronic Vehicle Information (EVIC)” in
“Understanding Your Instrument Panel” for fur-
ther information. If the “POWER STEERING SYSTEM OVER
TEMP” message and an icon are displayed on
the EVIC screen, it indicates that extreme steer-
ing maneuvers may have occurred, which
caused an over temperature condition in the
power steering system. You will lose power
steering assistance momentarily until the over
temperature condition no longer exists. Once
driving conditions are safe, then pull over and
let vehicle idle for a few moments until the light
turns off. Refer to “Electronic Vehicle Informa-
tion (EVIC)” in “Understanding Your Instrument
Panel” for further information.
NOTE:
•
Even if power steering assistance is no
longer operational, it is still possible to
steer the vehicle. Under these conditions
there will be a substantial increase in steer-
ing effort, especially at very low vehicle
speeds and during parking maneuvers.
•
If the condition persists, see your autho-
rized dealer for service.

WARNING!(Continued)
•HSA is not a parking brake. If you stop the
vehicle on a hill without putting the trans-
mission in PARK and using the parking
brake, it will roll down the hill and could
cause a collision with another vehicle or
object. Always remember to use the park-
ing brake while parking on a hill, and that
the driver is responsible for braking the
vehicle.
HSA Off
If you wish to turn off the HSA system, it can be
done using the Customer Programmable Fea-
tures in the Electronic Vehicle Information Cen-
ter (EVIC). Refer to “Electronic Vehicle Informa-
tion Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.
Ready Alert BrakingReady Alert Braking may reduce the time re-
quired to reach full braking during emergency
braking situations. It anticipates when an emer-
gency braking situation may occur by monitor-
ing how fast the throttle is released by the driver.
When the throttle is released very quickly,
Ready Alert Braking applies a small amount of
brake pressure. This brake pressure will not be
noticed by the driver. The brake system uses
this brake pressure to allow a fast brake re-
sponse if the driver applies the brakes.
Rain Brake SupportRain Brake Support may improve braking per-
formance in wet conditions. It will periodically
apply a small amount of brake pressure to
remove any water buildup on the front brake
rotors. It only functions when the windshield
wipers are in the LO or HI mode, it does not
function in the intermittent mode. When Rain
Brake Support is active, there is no notification
to the driver and no driver interaction is re-
quired.
Hill Descent Control (HDC) —
Four-Wheel Drive Models With MP3023
Two-Speed Transfer Case Only
HDC maintains vehicle speed while descending
hills during off-road driving situations and is
available in 4WD LOW range only. To enable
HDC, press the HDC switch or put the Selec-
Terrain™ system in “ROCK” mode (“ROCK”
mode is only available in 4WD LOW range).

CAUTION!(Continued)
•Observe the traction device manufactur-
er’s instructions on the method of installa-
tion, operating speed, and conditions for
use. Always use the suggested operating
speed of the device manufacturer’s if it is
less than 30 mph (48 km/h).
• Do not use traction devices on a compact
spare tire.
TIRE ROTATION
RECOMMENDATIONS
Non-Directional Tires OnlyTires on the front and rear axles of vehicles
operate at different loads and perform different
steering, handling, and braking functions. For
these reasons, they wear at unequal rates. These effects can be reduced by timely rotation
of tires. The benefits of rotation are especially
worthwhile with aggressive tread designs such
as those on On/Off-Road type tires. Rotation
will increase tread life, help to maintain mud,
snow, and wet traction levels, and contribute to
a smooth, quiet ride.
Refer to the “Maintenance Schedule” for the
proper maintenance intervals. More frequent
rotation is permissible if desired. The reasons
for any rapid or unusual wear should be cor-
rected prior to rotation being performed.
NOTE:
The premium Tire Pressure Monitor System
will automatically locate the pressure values
displayed in the correct vehicle position
following a tire rotation.
The suggested rotation method is the “forward-
cross” shown in the following diagram.
TIRE PRESSURE MONITOR
SYSTEM (TPMS)
The Tire Pressure Monitoring System (TPMS)
will warn the driver of a low tire pressure based
on the vehicle recommended cold tire placard
pressure.
The tire pressure will vary with temperature
by about 1 psi (7 kPa) for every 12°F (6.5°C).
This means that when the outside temperature
decreases, the tire pressure will decrease.
