2. Next, adjust the temperature you would like
the system to maintain by adjusting the driver
and front passenger temperature control but-
tons. Once the desired temperature is dis-
played, the system will achieve and automati-
cally maintain that comfort level.
3. When the system is set up for your comfort
level, it is not necessary to change the settings.
You will experience the greatest efficiency by
simply allowing the system to function auto-
matically.
NOTE:
•It is not necessary to move the tempera-
ture settings for cold or hot vehicles. The
system automatically adjusts the tem-
perature, mode and fan speed to provide
comfort as quickly as possible.
• The temperature can be displayed in U.S.
or Metric units by selecting the US/M
customer-programmable feature. Refer to
the “Electronic Vehicle Information Cen-
ter (EVIC) — Customer-Programmable
Features (SETUP)” in this section of the
manual. To provide you with maximum comfort in the
Automatic mode, during cold start-ups the
blower fan will remain on low until the engine
warms up. The blower will increase in speed
and transition into Auto mode.
Manual Operation
This system offers a full complement of manual
override features.
NOTE:
Each of these features operate indepen-
dently from each other. If any one feature is
controlled manually, temperature control
will continue to operate automatically.
There are seven fixed
blower speeds. Use
the outer dial control
to regulate the amount
of air forced through
the system in any
mode you select. The
blower speed in-
creases as you move
the control clockwise
and decreases when you move the control
counter-clockwise. The blower fan speed can be set to any fixed
speed by adjusting the blower control outer
dial. The fan will now operate at a fixed speed
until additional speeds are selected. This al-
lows the front occupants to control the volume
of air circulated in the vehicle and cancel the
Auto mode.
The operator can also select the direction of the
airflow by selecting one of the following posi-
tions.
Panel Mode
Air comes from the outlets in the instru-
ment panel. Each of these outlets can be
individually adjusted to direct the flow of
air. The air vanes of the center outlets and
outboard outlets can be moved up and down or
side to side to regulate airflow direction. There
is a shut off wheel located below the air vanes
to shut off or adjust the amount of airflow from
these outlets.
Bi-Level Mode Air comes from the instrument panel
outlets, floor outlets and defrost outlets.
190

NOTE:
In many temperature positions, the BI-
LEVEL mode is designed to provide cooler
air out of the panel outlets and warmer air
from the floor outlets.
Floor Mode
Air comes from the floor outlets. A slight
amount of air is directed through the
defrost and side window demister outlets.
Mix ModeAir comes from the floor, defrost and
side window demist outlets. This mode
works best in cold or snowy conditions.
It allows you to stay comfortable while
keeping the windshield clear.
Defrost Mode Air comes from the windshield and side
window demist outlets. Use Defrost
mode with maximum temperature set-
tings for best windshield and side window
defrosting. When the defrost mode is selected,
the blower will automatically default to medium-
high unless the blower is controlled manually. NOTE:
While operating in the other modes, the
system will not automatically sense the
presence of fog, mist or ice on the wind-
shield. Defrost mode must be manually se-
lected to clear the windshield and side
glass.
Air Conditioning (A/C)
The Air Conditioning (A/C) button allows the
operator to manually activate or deactivate the
air conditioning system. When in A/C mode and
the ATC is set to a cool temperature, dehumidi-
fied air flows through the air outlets. If Economy
mode is desired, press the A/C button to turn
off the A/C mode in the ATC display and
deactivate the A/C system.
NOTE:
•
If the system is in Mix, Floor or Defrost
Mode, the A/C can be turned off, but the
A/C system shall remain active to prevent
fogging of the windows.
• If fog or mist appears on the windshield or
side glass, select Defrost mode and in-
crease blower speed. Recirculation Control
When outside air contains smoke,
odors, or high humidity, or if rapid
cooling is desired, you may wish to
recirculate interior air by pressing
the RECIRCULATION control but-
ton. Recirculation mode should
only be used temporarily. The recirculation LED
will illuminate when this button is selected.
Push the button a second time to turn off the
Recirculation mode LED and allow outside air
into the vehicle.
NOTE:
In cold weather, use of Recirculation mode
may lead to excessive window fogging. The
Recirculation mode is not allowed in the
Floor/Defrost Mix and Defrost modes to im-
prove window clearing operation. Recircula-
tion will be disabled automatically if these
modes are selected.

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
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

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.
(Continued)
WARNING!(Continued)
• 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
pedal all the way to the floor and hold it. Then,
turn the ignition switch to the START position
and release it as soon as the starter engages.
The starter motor will disengage automatically
in 10 seconds. Once this occurs, release the
accelerator pedal, turn the ignition switch to the
LOCK position, wait 10 to 15 seconds, then
repeat the “Normal Starting” procedure.
CAUTION!
To prevent damage to the starter, wait 10 to
15 seconds before trying again.
After StartingThe idle speed is controlled automatically and it
will decrease as the engine warms up.

For example, if the driver shifts the transmission
into ERS 3 (third gear), the transmission will
never shift above third gear, but can shift down
to 2 (second) or 1 (first), when needed.
NOTE:
•If you pull and hold (not tap) the shift lever
to the left (-), the transmission will down-
shift to the lowest gear that can be at-
tained without overrevving the engine.
The display will show the gear the vehicle
is in and will limit the top gear to the one
displayed.
•
If you push and hold (not tap) the shift
lever to the right (+), the transmission will
exit the gear limiting mode and shift to the
appropriate gear. The display will read D .
3.6L and 3.0L Diesel Engine
When in the DRIVE position, the first tap to the
left (-) will shift down one gear and will display
that gear. For example, if you are in DRIVE and
are in fifth gear, when you tap the shift lever one
time to the left (-), the transmission will down-
shift to fourth gear and the display will show 4.
Another tap to the left (-) will shift the transmis-
sion into third gear. 5.7L Engine
On vehicles equipped with the 5.7L engine,
use of ERS (or TOW/HAUL mode) also enables
an additional underdrive gear which is not
normally used during through-gear accelera-
tions. This additional gear improves vehicle
performance and cooling capability when tow-
ing a trailer on certain grades. ERS 1, 2, and 3
are underdrive gears; ERS 4 is direct drive. ERS
5 (Overdrive) is the same as the normal 4th
gear. When in the DRIVE position in first through
fourth gear, the first tap to the left (-) will display
the ERS designation for the current gear (the
transmission will not downshift). For example, if
you are in DRIVE and are in third (direct) gear,
when you tap the shift lever one time to the left
(-), the display will show 4 (ERS 4 is direct
gear). Another tap to the left (-) will shift the
transmission down to ERS 3 (the added under-
drive gear). When in the DRIVE position in fifth
gear, the first tap to the left (-) will downshift the
transmission and display 5 (ERS 5 is the same
as normal fourth gear). Another tap to the left (-)
will shift the transmission down to ERS 4 (direct
gear).
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid.

NOTE:
To select the proper gear position for maxi-
mum deceleration (engine braking), move
the shift lever to the left “D(-)” and hold it
there. The transmission will shift to the
range from which the vehicle can best be
slowed down.
207

Overdrive Operation
The automatic transmission includes an elec-
tronically controlled Overdrive (fifth gear for
3.6L and 3.0L Diesel engine, fourth and fifth
gears for 5.7L engine). The transmission will
automatically shift to Overdrive, if the following
conditions are present:
•the shift lever is in DRIVE;
• the engine coolant has reached normal op-
erating temperature;
• vehicle speed is above approximately
30 mph (48 km/h);
• the TOW/HAUL switch has not been acti-
vated;
• transmission has reached normal operating
temperature.
NOTE:
If the vehicle is started in extremely cold
temperatures, the transmission may not
shift into Overdrive and will automatically
select the most desirable gear for operation
at this temperature. Normal operation will
resume when the transmission fluid tem-
perature has risen to a suitable level. Refer to the “Note” under “Torque Converter
Clutch” in this section.
During cold temperature operation you may
notice delayed upshifts, depending on en-
gine and transmission temperature. This
feature improves the warm-up time of the
engine and transmission.
If the transmission temperature gets ex-
tremely hot, the transmission will automati-
cally select the most desirable gear for op-
eration at this temperature. If the
transmission temperature becomes hot
enough, the “TRANSMISSION OVER TEMP”
message may display, and the transmission
may downshift out of Overdrive until the
transmission cools down. After cool down,
the transmission will resume normal opera-
tion.
The transmission will downshift from Overdrive,
to the most desirable gear, if the accelerator
pedal is fully pressed at vehicle speeds above
approximately 35 mph (56 km/h).
When to Use TOW/HAUL Mode –
If Equipped
When driving in hilly areas, towing a trailer,
carrying a heavy load, etc., and frequent trans-
mission shifting occurs, press the TOW/HAUL
switch. This will improve performance and re-
duce the potential for transmission overheating
or failure due to excessive shifting. When oper-
ating in TOW/HAUL mode, the transmission will
shift into direct gear and Overdrive will be
enabled under steady cruise conditions.
TOW/HAUL Switch

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. Activates 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.

QUADRA-LIFT™ — IF EQUIPPED
Description
The Quadra-Lift™ air suspension system pro-
vides full time load leveling capability along
with the benefit of being able to adjust vehicle
height by the push of a button.

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 immediately
after 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.

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.
After Driving Off-RoadOff-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, steer-
ing, suspension, and exhaust system for
damage.
• Inspect the radiator for mud and debris and
clean as required.
• Check threaded fasteners for looseness,
particularly on the chassis, drivetrain com-
ponents, steering, and suspension. Re-
tighten 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, wa-
ter, or similar dirty conditions, have the ra-
diator, fan, brake rotors, wheels, brake lin-
ings, and axle yokes inspected and cleaned
as soon as possible.
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.
• If you experience unusual vibration after
driving in mud, slush or similar conditions,
check the wheels for impacted material. Im-
pacted material can cause a wheel imbal-
ance and freeing the wheels of it will correct
the situation.
POWER STEERING
3.6L Engine and 3.0L Diesel Engine
Your 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 the
electro-hydraulic power steering system expe-
riences 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
