EDUCTION ACTIONS — IF EQUIPPED
This vehicle is equipped with an Intelligent Battery
Sensor (IBS) to perform additional monitoring of
the electrical system and status of the vehicle
battery.
In cases when the IBS detects charging system
failure, or the vehicle battery conditions are
deteriorating, electrical load reduction actions will
take place to extend the driving time and distance
of the vehicle. This is done by reducing power to or
turning off non-essential electrical loads.
Load reduction is only active when the engine is
running. It will display a message if there is a risk
of battery depletion to the point where the vehicle
may stall due to lack of electrical supply, or will not
restart after the current drive cycle.

SPORT MODE — IF EQUIPPED

SPORT Mode

Your vehicle is equipped with a Sport Mode
feature. When activated, the engine and
transmission, steering and suspension (if
equipped with air suspension) are all set to their
SPORT settings. Sport Mode will provide improved
throttle response and modified transmission shift
points as well as firmer suspension and steering
for an enhanced driving experience. This mode
may be activated and deactivated by pushing the
SPORT ON button on the instrument panel switch
bank or by selecting SPORT mode using the
Selec-Terrain switch (if equipped). When Sport
Mode has been activated an indicator light will
illuminate in the instrument cluster.
FOUR-WHEEL DRIVE OPERATION
The driveline is equipped with a Front Axle
Disconnect (FAD) for the one-speed and two-speed
drivelines. The FAD operation is fully automated
and controlled by the Drivetrain Control Module
(DTCM). It does not require any customer input to
engage. The FAD is set to connect, disconnect and
provide 4WD function based on certain set
conditions detected by the DTCM, including but not
limited to the following:
Ambient temperature
Wipers
Selec-Terrain Mode selection
Wheel-slip detection
The FAD is actuated only in 4WD HI range and
stays connected for 4WD LOW.
QUADRA-TRAC I OPERATING
I
NSTRUCTIONS/PRECAUTIONS —
I
F EQUIPPED
The Quadra-Trac I is a single-speed (HI range only)
transfer case, which enables on-demand
four-wheel drive with active torque management.
No driver interaction is required. The Brake
Traction Control (BTC) system, which combines
standard ABS and Traction Control, provides
resistance to any wheel that is slipping to allow
additional torque transfer to wheels with traction.
NOTE:The Quadra-Trac I system is not appropriate for
conditions where 4WD LOW range is recom -
mended Ú page 200.
QUADRA-TRAC II OPERATING
I
NSTRUCTIONS/PRECAUTIONS —
I
F EQUIPPED
The Quadra-Trac II system comes equipped with a
customer-selectable electronically operated
on-demand transfer case with active torque
management in all driveable ranges. This transfer
case provides the following operating range
positions:
4WD HI
N (NEUTRAL)
4WD LOW
When additional tractive effort and torque are
required, the 4WD LOW position can be used. The
4WD LOW position is intended for loose, slippery
road surfaces only. Driving in the 4WD LOW
position on dry, hard-surfaced roads may cause
increased tire wear and damage to driveline
components.
When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that of
the normal 4WD HI position at a given road speed.
Take care not to overspeed the engine and do not
exceed 25 mph (40 km/h).

STARTING AND OPERATING135

Selec-Terrain

Selec-Terrain consists of the following positions:
ROCK – Off-road calibration is only available in
4WD LOW. The vehicle is raised (if equipped
with air suspension) for improved ground clear -
ance. Traction-based tuning with improved
steerability for use on high traction off-road
surfaces. 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 (OR2). If the Selec-Terrain switch is
in ROCK mode, and the transfer case is
switched from 4WD LOW to 4WD HI, the
Selec-Terrain system will return to AUTO.
SAND/MUD – Off-road calibration for use on low
traction surfaces such as mud or sand. 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 (OR1).
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 default ride height for SNOW is
Normal Ride Height (NRH).
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 acceleration
over two-wheel drive vehicles. If the suspension
is already in OR1 or OR2, the vehicle will not
lower to NRH with Auto selection as to maintain
capability.
NOTE:If equipped with air suspension, the level will only
raise to Normal Ride Height (NRH) in the AUTO
mode. If the vehicle is in OR1 or OR2 the height will
not lower automatically until defined speed
thresholds are exceeded.
SPORT – This mode is only available in 4WD HI.
When activated, the engine and transmission,
steering and suspension (if equipped with air
suspension) are all set to their SPORT settings.
SPORT mode will provide improved throttle
response and modified transmission shift
points as well as firmer suspension and
steering, the vehicle will also be dropped to Aero
Height for an enhanced driving experience.
When SPORT mode has been activated, an indi -
cator light will illuminate in the instrument
cluster.

23_WL_OM_EN_USC_t.book Page 135

STARTING AND OPERATING137
Normal Ride Height (NRH) 0.0 inches (0 mm) –
This is the standard position of the suspension
and is meant for normal driving.
Aero Height (Lowers the vehicle approximately
-0.8 inches [-21 mm] Front and -1.0 inches
[-25 mm] Rear) – This position provides
improved aerodynamics by lowering the vehicle.
The vehicle will automatically enter Aero when
the vehicle speed remains between 62 mph
(100 km/h) and 66 mph (106 km/h) for greater
than 20 seconds or if the vehicle speed exceeds
66 mph (106 km/h). The vehicle will return to
NRH from Aero if the vehicle speed remains
between 30 mph (48 km/h) and 35 mph
(56 km/h) for greater than 20 seconds or if the
vehicle speed falls below 30 mph (48 km/h).
The vehicle will enter Aero, regardless of vehicle
speed if the vehicle is in SPORT mode.
Entry/Exit Height (Lowers the vehicle approxi -
mately -1.8 inches [-46 mm] Front and
-2.0 inches [-50 mm] Rear) – 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 Entry/Exit, push the DOWN
button twice from NRH while the vehicle speed
is below 4 mph (6 km/h). To exit Entry/Exit,
push the UP button twice while in Entry/Exit or
drive the vehicle over 6 mph (10 km/h).
NOTE:Automatic lowering of the vehicle into Entry/Exit
can be enabled through the Uconnect Touch -
screen Radio by selecting the “Auto Entry/Exit”
setting. If this feature is enabled, the vehicle will
only lower if the gear selector is in PARK, the
terrain switch is in AUTO, the transfer case is in
AUTO and the vehicle level is either in Normal or
Aero Height. The vehicle will not automatically
lower to Entry/Exit height if the air suspension level
is in OR2 or OR1. If the vehicle is equipped with
Intrusion Theft Module (ITM), the lowering will be
suppressed when the ignition is switched OFF and
the door is open to prevent setting the alarm off.
The Selec-Terrain system 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
Ú page 134.
The system requires that the engine be running for
all changes. When lowering the vehicle all of the
doors 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/are
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.
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 feature
which allows the automatic leveling to be disabled
Ú
page 204.
Default Ride Height
Select Aero Height or Normal Ride Height as the
default for all vehicle speeds and operation.
This is the selected height that the suspension
will level for speed changes (e.g. raising from
Entry/Exit Height at speed, lowering from Off
Road Height at speed, etc.).
Default ride height can be changed by manually
adjusting the ride height switch to Normal Ride
Height or Aero Height and staying in the
selected height for 2.5 seconds. It will be stored
as the default ride height and the height will be
maintained until a new default ride height is
selected.
If equipped with a touchscreen radio, all enabling/
disabling of air suspension features must be done
through the radio Ú page 204.
