3. If the shift lever is not in PARK, the ENGINE
START/STOP button must be held for two sec-onds and vehicle speed must be above 5 mph
(8 km/h) before the engine will shut off. The
ignition switch position will remain in the ACC
position until the shift lever is in PARK and the
button is pressed twice to the OFF position. 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 (In
PARK or NEUTRAL Position)
The Keyless Enter-N-Go feature operates simi-
lar to an ignition switch. It has four positions,
OFF, ACC, RUN and START. To change the
217

ignition switch positions without starting the
vehicle 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

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 liquids
into the throttle body air inlet opening in an
attempt to start the vehicle. This could
result in a flash fire causing serious per-
sonal 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 converter
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. Clearing a Flooded Engine
(Using ENGINE START/STOP Button)
If the engine fails to start after you have fol-
lowed the “Normal Starting” or “Extreme Cold
Weather
procedures, it may be flooded. To
clear any excess fuel, press and hold the brake
pedal, push the accelerator pedal all the way to
the floor and hold it, then press and release the
ENGINE START/STOP button once. The starter
motor will engage automatically, run for 10 sec-
onds, and then disengage. Once this occurs,
release the accelerator pedal and the brake
pedal, wait 10 to 15 seconds, then repeat the
“Normal Starting” procedure.
Clearing A Flooded Engine
(Using Fob With Integrated Key)
If the engine fails to start after you have fol-
lowed the “Normal Starting” or “Extreme Cold
Weather” procedures, it may be flooded. To
clear any excess fuel, push the accelerator

Selec-Terrain™ consists of the following posi-
tions:
•Sport – Dry weather, on-road calibration.
Only available in 4WD High range. Perfor-
mance based tuning that provides a rear
wheel drive feel but with improved handling
and acceleration over a two-wheel drive ve-
hicle. The Electronic Stability Control will set
to allow more driver control of vehicle while
maintaining safe handling controls. The ve-
hicle will lower (if equipped with Air Suspen-
sion) to Aero Mode in High Range. 4WD Low
is not available in SPORT mode, if 4WD Low
is selected the Selec-Terrain™ will automati-
cally switch back to AUTO.
• Snow – Tuning set for additional stability in
inclement weather. Use on and off road on
loose traction surfaces such as snow. When
in Snow mode (depending on certain oper-
ating conditions), the transmission may use
second gear (rather than first gear) during
launches, to minimize wheel slippage. If equipped with air suspension, the level will
change to Normal Ride Height (NRH) if the
transfer case is in high range. The level will
change to Off-Road 1 if the transfer case is in
Low range.
• 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 accel-
eration 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 trac-
tion. Some binding may be felt on less for-
giving surfaces. The electronic brake con-
trols are set to limit traction control
management of throttle and wheel spin. If
equipped with air suspension, 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™ system will return to AUTO.

•Park Mode (Lowers the vehicle approxi-
mately 1.5 in (38 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 Park Mode, press the “Down” button
once while the vehicle speed is below
25 mph (40 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 Park Mode change will
be cancelled. To exit Park Mode, press the
“Up” button once while in Park Mode or drive
the vehicle over 15 mph (24 km/h).
The Selec-Terrain™ switch will automatically
change the vehicle to the proper height based
on the position of the Selec-Terrain™ switch.
The height can be changed from the default
Selec-Terrain™ setting by normal use of the air
suspension buttons. Refer to “Selec-Terrain™”
in “Starting and Operating” for further informa-
tion. 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
appearance.
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.

OperationThe indicator lamps 3 through 6 will illuminate
to show the current position of the vehicle.
Flashing 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 indica-
tor lamp is the position the system is working to
achieve. When lowering, if multiple indicators
are flashing on theUpbutton 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 cur-
rent 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 conditions (i.e. vehicle speed, etc).
Pressing the “DOWN” button once will move
the suspension one position lower from the
current level, assuming all conditions are met
(i.e. engine running, doors closed, speed be-
low 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
indicator 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 run-
ning and all doors remain closed.
ON-ROAD DRIVING TIPSUtility vehicles have higher ground clearance
and a narrower track to make them capable of
performing in a wide variety of off-road appli-
cations. Specific design characteristics give
them a higher center of gravity than ordinary
cars.
238

NOTE:
Your vehicle is capable of water fording in
up to 20 inches (51 cm) of water, while
crossing small rivers or streams. To main-
tain optimal performance of your vehicle’s
heating and ventilation system it is recom-
mended to switch the system into recircula-
tion mode during water fording.
CAUTION!
When driving through water, do not exceed
5 mph (8 km/h). Always check water depth
before entering, as a precaution, and check all
fluids afterward. Driving through water may
cause damage that may not be covered by the
New Vehicle Limited Warranty.
Driving through water more than a few inches/
centimeters deep will require extra caution to
ensure safety and prevent damage to your
vehicle. If you must drive through water, try to
determine the depth and the bottom condition
(and location of any obstacles) prior to enter-
ing. Proceed with caution and maintain a steady controlled speed less than 5 mph
(8 km/h) in deep water to minimize wave ef-
fects.
Flowing Water
If the water is swift flowing and rising (as in
storm run-off), avoid crossing until the water
level recedes and/or the flow rate is reduced. If
you must cross flowing water avoid depths in
excess of 9 inches (23 cm). The flowing water
can erode the streambed, causing your vehicle
to sink into deeper water. Determine exit
point(s) that are downstream of your entry point
to allow for drifting.
Standing Water
Avoid driving in standing water deeper than
20 inches (51 cm), and reduce speed appro-
priately to minimize wave effects. Maximum
speed in 20 inches (51 cm) of water is less than
5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your
vehicle fluids and lubricants (engine oil, trans-
mission oil, axle, transfer case) to assure the
fluids have not been contaminated. Contami-
nated fluid (milky, foamy in appearance) shouldbe flushed/changed as soon as possible to
prevent component damage.
Driving In Snow, Mud And SandIn 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. Refer to “Four-
Wheel Drive Operation” in “Starting and Oper-
ating” for further information. Do not shift to a
lower gear than necessary 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 trans-
mission to a lower gear and shift the transfer
case to 4WD LOW. Use first gear and 4WD
LOW for very steep hills.

CAUTION!
•Failure to properly maintain your vehicle or
perform repairs and service when neces-
sary could result in more costly repairs,
damage to other components or negatively
impact vehicle performance. Immediately
have potential malfunctions examined by
an authorized dealership or qualified repair
center.
• Your vehicle has been built with improved
fluids that protect the performance and
durability of your vehicle and also allow
extended maintenance intervals. Do not
use chemical flushes in these components
as the chemicals can damage your engine,
transmission, power steering or air condi-
tioning. Such damage is not covered by the
New Vehicle Limited Warranty. If a flush is
needed because of component malfunc-
tion, use only the specified fluid for the
flushing procedure.Engine Oil – Gasoline Engines
Checking Oil Level
To assure proper lubrication of your vehicle’s
engine, the engine oil must be maintained at
the correct level. The best time to check the
engine oil level is about five minutes after a fully
warmed up engine is shut off or before starting
the engine after it has sat overnight.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
readings. Maintain the oil level in the SAFE level
range. Adding 1 U.S. Quart (0.95L) of oil when
the level is at the bottom of the SAFE range will
result in the level being at the top of the SAFE
range.
CAUTION!
Overfilling or underfilling the crankcase will
cause aeration or loss of oil pressure. This
could damage your engine. Change Engine Oil
Refer to the “Maintenance Schedule” for the
proper maintenance intervals.

4. Install the wiper blade pivot pin into the
wiper blade holder at the end of the wiper arm,
and firmly press the wiper blade until it snaps
into place.
5. Lower the wiper blade and snap the pivot
cap into place.
Adding Washer FluidThe fluid reservoir for the windshield washers
and the rear window washer is shared. The fluid
reservoir is located in the engine compartment,
be sure to check the fluid level at regular
intervals. Fill the reservoir with windshield
washer solvent only (not radiator antifreeze).
When refilling the washer fluid reservoir, take
some washer fluid and apply it to a cloth or
towel and wipe clean the wiper blades, this will
help blade performance. To prevent freeze-up
of your windshield washer system in cold
weather, select a solution or mixture that meets
or exceeds the temperature range of your cli-
mate. This rating information can be found on
most washer fluid containers.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite and
burn you. Care must be exercised when filling
or working around the washer solution.
Exhaust SystemThe best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained engine exhaust system.
If you notice a change in the sound of the
exhaust system; or if the exhaust fumes can be
detected inside the vehicle; or when the under-
side or rear of the vehicle is damaged; have an
authorized technician inspect the complete ex-
haust system and adjacent body areas for
broken, damaged, deteriorated, or misposi-
tioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the
passenger compartment. In addition, inspect
the exhaust system each time the vehicle is
raised for lubrication or oil change. Replace as
required.
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you uncon-
scious and can eventually poison you. To
avoid breathing CO, refer to “Safety Tips/
Exhaust Gas” in “Things To Do Before Starting
Your Vehicle” for further information.
CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will de-
stroy the effectiveness of the catalyst as an
emissions control device and may seriously
reduce engine performance and cause seri-
ous damage to the engine.
Under normal operating conditions, the cata-
lytic converter will not require maintenance.
However, it is important to keep the engine
properly tuned to assure proper catalyst opera-
tion and prevent possible catalyst damage.

MAINTENANCE SCHEDULE
Maintenance Schedule – Gasoline
Engine
The Scheduled Maintenance services listed in
this manual must be done at the times or
mileages specified to protect your vehicle war-
ranty and ensure the best vehicle performance
and reliability. More frequent maintenance may
be needed for vehicles in severe operating
conditions, such as dusty areas and very short
trip driving. Inspection and service should also
be done anytime a malfunction is suspected.
The oil change indicator system will remind you
that it is time to take your vehicle in for sched-
uled maintenance.
On Electronic Vehicle Information Center
(EVIC) equipped vehicles “Oil Change Re-quired” will be displayed in the EVIC and a
single chime will sound, indicating that an oil
change is necessary.
The oil change indicator message will illumi-
nate approximately 7,000 miles (11 200 km)
after the most recent oil change was per-
formed. Have your vehicle serviced as soon as
possible, within 500 miles (800 km).
NOTE:
•
The oil change indicator message will not
monitor the time since the last oil change.
Change your vehicles oil if it has been
6 months since your last oil change even
if the oil change indicator message is
NOT illuminated.
• Change your engine oil more often if you
drive your vehicle off-road for an ex-
tended period of time. •
Under no circumstances should oil
change intervals exceed 7,500 miles
(12 000 km) or 6 months, whichever
comes first.
Your authorized dealer will reset the oil change
indicator message after completing the sched-
uled oil change. If this scheduled oil change is
performed by someone other than your autho-
rized dealer the message can be reset by
referring to the steps described under ”Elec-
tronic Vehicle Information Center” in “Under-
standing Your Instrument Panel” for further in-
formation.
