Recirculation
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 button. The
recirculation indicator will illuminate when this button is
selected. Push the button a second time to turn off the
Recirculation mode and allow outside air into the vehicle.
NOTE: In cold weather, use of Recirculation mode may
lead to excessive window fogging. The recirculation
feature may be unavailable (soft button greyed out) if
conditions exist that could create fogging on the inside of
the windshield. On systems with Manual Climate Con-
trols, the Recirculation mode is not allowed in Defrost
mode to improve window clearing operation. Recircula-
tion will be disabled automatically if this mode is se-
lected. Attempting to use Recirculation while in this mode will cause the LED in the control button to blink
and then turn off.Automatic Temperature Control (ATC)

398 STARTING AND OPERATING

Selec-Terrain™ consists of the following positions:
•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 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 im-
proved handling and acceleration over two-wheel
drive vehicles. If equipped with air suspension, the
level will change to NRH.
• Sand – Off road calibration for use on low traction
surfaces such as sand or wet grass. Driveline is maxi-
mized 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 suspension, the level
will change to Off-Road 1.
Selec-Terrain™ Switch

•Mud – Off road calibration for use on low traction
surfaces such as mud. 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 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 De-
scent 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.Electronic Vehicle Information Center (EVIC)
Display Messages
When the appropriate conditions exist, a message will
appear in the EVIC display. Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.

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 Mode change will be can-
celled. To exit Entry/Exit Mode, press the “Up” button
once while in Entry/Exit Mode or drive the vehicle
over 15 mph (24 km/h).
NOTE:
Automatic lowering of the vehicle into Entry/Exit
Mode can be enabled through the Uconnect® Touch-Screen
Radio. If this feature is enabled, the vehicle will only lower
if the shift lever is in PARK, the terrain switch is in
AUTO, the transfer-case is in AUTO” and the vehicle
level should be either in Normal or Aero Mode. The Vehicle
will not automatically lower if the air suspension level is in
Off Rd 2 or Off Rd 1. If the vehicle is equipped with
Intrusion Theft Module (ITM), the lowering will be sup-
pressed when the ignition is switched Off and the Door is
Open to prevent setting the alarm Off.
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.

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.

The best time to check the engine oil level is about five
minutes after a fully warmed up engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the
dipstick. Adding one quart of oil when the reading is at
the bottom of the SAFE zone will result in a reading at the
top of the safe zone on these engines.
CAUTION!
Overfilling or underfilling the crankcase will cause
aeration or loss of oil pressure. This could damage
your engine.
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 in-
tervals exceed 10,000 miles (16,000 km) or twelve
months, whichever occurs first.

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.
WARNING!
•
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you unconscious
and can eventually poison you. To avoid breathing
CO, refer to “Safety Tips/Exhaust Gas” in “Things
To Know Before Starting Your Vehicle” for further
information.
