SPORT MODE — IF
EQUIPPED
Your vehicle is equipped with a Sport Mode
feature. This mode is a configuration set up
for typical enthusiast driving. The engine,
transmission, and steering systems are all set
to their SPORT settings. Sport Mode will
provide improved throttle response and modi-
fied shifting for an enhanced driving experi-
ence, as well the greatest amount of steeringfeel. This mode may be activated and deac-
tivated by pushing the Sport button on the
instrument panel switch bank.
FOUR WHEEL DRIVE
OPERATION
Quadra-Trac I Operating Instructions/
Precautions — If Equipped
The Quadra-Trac I is a single-speed (HI range
only) transfer case, which provides conve-
nient full-time four-wheel drive. No driver
interaction is required. The Brake Traction
Control (BTC) System, which combines stan-
dard ABS and Traction Control, provides re-
sistance to any wheel that is slipping to allow
additional torque transfer to wheels with trac-
tion.
NOTE:
The Quadra-Trac I system is not appropriate
for conditions where 4WD LOW range is rec-
ommended. Refer to “Off-Road Driving Tips”
in “Starting And Operating” in the Owner’s
Manual.
Quadra-Trac II Operating Instructions/
Precautions — If Equipped
The Quadra-Trac II transfer case is fully au-
tomatic in the normal driving 4WD AUTO
mode. The Quadra-Trac II transfer case pro-
vides three mode positions:
• 4WD HI
• NEUTRAL
• 4WD LOW
This transfer case is fully automatic in the
4WD HI mode.
When additional traction is required, the
4WD LOW position can be used to lock the
front and rear driveshafts together and force
the front and rear wheels to rotate at the same
speed. 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.
Sport Mode Button
159

When operating your vehicle in 4WD LOW,
the engine speed is approximately three
times that of the 4WD HI position at a given
road speed. Take care not to overspeed the
engine and do not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type, and
circumference on each wheel. Any difference
will adversely affect shifting and cause dam-
age to the transfer case.
Because four-wheel drive provides improved
traction, there is a tendency to exceed safe
turning and stopping speeds. Do not go faster
than road conditions permit.
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
transfer case in the NEUTRAL position
without first fully engaging the parking
brake. The transfer case NEUTRAL posi-
tion disengages both the front and rear
drive shafts from the powertrain and will
allow the vehicle to roll, even if the trans-
mission is in PARK. The parking brake
WARNING!
should always be applied when the driver
is not in the vehicle.
Shift Positions
For additional information on the appropriate
use of each 4WD system mode position, see
the information below:
4WD AUTO
This range is used on surfaces such as ice,
snow, gravel, sand, and dry hard pavement.
NOTE:
Refer to “Selec-Terrain — If Equipped” fur-
ther on in this section for further information
on the various positions and their intended
usages.
NEUTRAL
This range disengages the driveline from the
powertrain. It is to be used for flat towing
behind another vehicle. Refer to “Recre-
ational Towing” in “Starting And Operating”
for further information.
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
transfer case in the NEUTRAL position
without first fully engaging the parking
brake. The transfer case NEUTRAL posi-
tion disengages both the front and rear
drive shafts from the powertrain and will
allow the vehicle to roll, even if the trans-
mission is in PARK. The parking brake
should always be applied when the driver
is not in the vehicle.
4WD LOW
This range is for low speed four-wheel drive.
It provides an additional gear reduction
which allows for increased torque to be deliv-
ered to both the front and rear wheels while
providing maximum pulling power for loose,
slippery road surfaces only. Do not exceed
25 mph (40 km/h).
NOTE:
Refer to “Selec-Terrain — If Equipped” for
further information on the various positions
and their intended usages.

Quadra-Drive II System — If Equipped
The optional Quadra-Drive II System features
two torque transfer couplings. The couplings
include an Electronic Limited-Slip Differen-
tial (ELSD) rear axle and the Quadra-Trac II
transfer case. The optional ELSD axle is fully
automatic and requires no driver input to
operate. Under normal driving conditions,
the unit functions as a standard axle, balanc-
ing torque evenly between left and rightwheels. With a traction difference between
left and right wheels, the coupling will sense
a speed difference. As one wheel begins to
spin faster than the other, torque will auto-
matically transfer from the wheel that has
less traction, to the wheel that has traction.
While the transfer case and axle coupling
differ in design, their operation is similar.
Follow the Quadra-Trac II transfer case shift-
ing information, preceding this section, for
shifting this system.
QUADRA-LIFT — IF
EQUIPPED
Description
The Quadra-Lift air suspension system pro-
vides full time load leveling capability along
with the benefit of vehicle height adjustment
by the push of a button. The vehicle will
automatically raise and lower the ride height
to adapt to the appropriate driving condi-
tions. At higher speeds, the vehicle will lower
to an aerodynamic ride height and when op-
erating in off-road modes, the vehicle will
raise the ride height accordingly. The buttonsnear the terrain switch in the center console
area can be used to set preferred ride height
to match the appropriate conditions.
•Normal Ride Height (NRH)– This is the stan-
dard position of the suspension and is
meant for normal driving.

•Off-Road 1 (OR1) (Raises the vehicle approxi-
mately 1.1 inches (28 mm))– This is the
primary position for all off-road driving until
OR2 is needed. A smoother and more com-
fortable ride will result. Push the “UP”
button once from the NRH position while
the vehicle speed is below 38 mph
(61 km/h). When in the OR1 position, if the
vehicle speed remains between 40 mph
(64 km/h) and 50 mph (80 km/h) for
greater than 20 seconds or if the vehicle
speed exceeds 50 mph (80 km/h), the
vehicle will be automatically lowered to
NRH.
•Off-Road 2 (OR2) (Raises the vehicle approxi-
mately 2.2 inches (55 mm))– This position is
intended for off-roading use only where
maximum ground clearance is required. To
enter OR2, push the “UP” button twice
from the NRH position or once from the
OR1 position while vehicle speed is below
20 mph (32 km/h). While in OR2, if the
vehicle speed exceeds 25 mph (40 km/h)
the vehicle height will be automatically
lowered to OR1.•Aero Mode (Lowers the vehicle approximately
0.6 inches (15 mm))– This position provides
improved aerodynamics by lowering the ve-
hicle. The vehicle will automatically enter
Aero Mode when the vehicle speed remains
between 52 mph (83 km/h) and 56 mph
(90 km/h) for greater than 20 seconds or if
the vehicle speed exceeds 56 mph
(90 km/h). The vehicle will return to NRH
from Aero Mode if the vehicle speed re-
mains between 20 mph (32 km/h) and
25 mph (40 km/h) for greater than 20 sec-
onds or if the vehicle speed falls below
20 mph (32 km/h). The vehicle will enter
Aero Mode, regardless of vehicle speed if
the vehicle is in “SPORT” mode.
•Entry/Exit Mode (Lowers the vehicle approxi-
mately 1.6 inches (40 mm)– This position
lowers the vehicle for easier passenger en-
try and exit as well as lowering the rear of
the vehicle for easier loading and unloading
of cargo. To enter Entry/Exit Mode, push the
“DOWN” button once from (NRH) 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 between15 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 cancelled.
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
gear selector 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 suppressed 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
STARTING AND OPERATING
164

Selec-Terrain setting by normal use of the air
suspension buttons. Refer to “Selec-Terrain”
in “Starting And Operating” for further infor-
mation.
The system requires that the engine be run-
ning for all changes. When lowering the ve-
hicle 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/are closed.
The Quadra-Lift air suspension system uses a
lifting and lowering pattern which keeps the
headlights from incorrectly shining into on-
coming 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 oper-
ates briefly, this is normal. The system is
correcting the position of the vehicle to en-
sure 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. Refer to “Uconnect Settings” in
“Multimedia” for further information.
For further information refer to “Driving Tips”
in “Starting And Operating” in the Owner’s
Manual.
NOTE:
