•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 temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized 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 trans-
mission 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 Emergen-
cies” for further information.

STARTING AND OPERATING 443

Selec-Terrain™ consists of the following positions:
•Sport– Dry weather, on-road calibration. Only avail-
able in 4WD High range. Performance based tuning
that provides a rear wheel drive feel but with im-
proved handling and acceleration over a two-wheel
drive vehicle. The Electronic Stability Control will set
to allow more driver control of vehicle while maintain-
ing safe handling controls. The vehicle will lower (if
equipped with Air Suspension) to Aero Mode in High
Range. 4WD Low is not available in SPORT mode, if
4WD Low is selected the Selec-Terrain™ will auto-
matically 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 operating conditions), the transmission may
use second gear (rather than first gear) during
launches, to minimize wheel slippage. If equippedwith 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 im-
proved handling and acceleration 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.
474 STARTING AND OPERATING

Selec-Terrain™ knob is turned to the “SPORT” posi-
tion. Turning the Selec-Terrain™ knob to the “AUTO”
position will return the system to normal operation.
•Park Mode (Lowers the vehicle approximately 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 information.
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 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.
478 STARTING AND OPERATING

Operation
The 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 the
Upbutton the lowest solid indicator lamp is the posi-
tion 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 conditions (i.e. vehicle
speed, etc).Pressing the “DOWN” button once will move the sus-
pension one position lower from the current level, as-
suming all conditions are met (i.e. engine 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. vehicle 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.
480 STARTING AND OPERATING

Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
SNOW PLOW
Snow plows, winches, and other aftermarket equipment
shouldnotbe added to the front end of your vehicle. The
airbag crash sensors may be affected by the change in the
front end structure. The airbags could deploy unexpect-
edly or could fail to deploy during a collision.
WARNING!
Do not add a snow plow, winches, or any other
aftermarket equipment to the front of your vehicle.
This could adversely affect the functioning of the
airbag system and you could be injured.
570 STARTING AND OPERATING

CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads HOT
(H), pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on HOT (H), and you hear continuous
chimes, turn the engine off immediately and call for
service.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.
JACKING AND TIRE CHANGING
WARNING!
•Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.
•Being under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
under a vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service center
where it can be raised on a lift.
•Never start or run the engine while the vehicle is
on a jack.

WHAT TO DO IN EMERGENCIES 583

Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
Refer to the “Maintenance Schedule” for further informa-
tion.
NOTE:Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever occurs first.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only
recommends engine oils that are API Certified and meet
the requirements of Chrysler Material Standard MS-6395.
American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American Pe-
troleum Institute (API). The manu-
facturer only recommends API Cer-
tified engine oils.
CAUTION!
Do not use chemical flushes in your engine oil as the
chemicals can damage your engine. Such damage is
not covered by the New Vehicle Limited Warranty.
614 MAINTAINING YOUR VEHICLE

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 climate. 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 System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained 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 underside or rear of the vehicle is damaged;
have an authorized technician inspect the complete ex-
haust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams
or loose connections could permit exhaust fumes to seep
into the passenger compartment. In addition, have the
exhaust system inspected each time the vehicle is raised
for lubrication or oil change. Replace as required.
624 MAINTAINING YOUR VEHICLE

MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that ser-
vice is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or
cold ambient temperatures, and E85 fuel usage will
influence when the “Oil Change Required” message is
displayed. Severe Operating Conditions can cause the
change oil message to illuminate as early as 3,500 miles
(5,600 km) since last reset. Have your vehicle serviced as
soon as possible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If ascheduled oil change is performed by someone other
than your authorized dealer, the message can be reset by
referring to the steps described under “Electronic Vehicle
Information Center (EVIC)/Oil Change Required” in
“Understanding Your Instrument Panel” for further in-
formation
NOTE:Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
Once A Month Or Before A Long Trip:
•Check engine oil level
•Check windshield washer fluid level
•Check the tire inflation pressures and look for unusual
wear or damage
