If the engine fails to start after you have followed
the "Normal Starting" procedure and has not
experienced an extended park condition (i.e.,
parked for more than 30 days), it may be flooded.
Push the accelerator pedal all the way to the floor
and hold it there while the engine is cranking. This
should clear any excess fuel in case the engine is
flooded. The starter motor will engage
automatically, run for 10 seconds, and then
disengage. Once this occurs, release the
accelerator pedal and brake pedal, wait 10 to
15 seconds, then repeat the “Normal Starting”
procedure.
WARNING!
If vehicle speed is above 1.2 mph (1.9 km/h),
the transmission will default to NEUTRAL until
the vehicle speed drops below 1.2 mph (1.9 km/

outlet with a grounded, three-wire extension cord.
The engine block heater must be plugged in at
least one hour to have an adequate warming effect
on the engine.
The engine block heater cord is coiled and
strapped right behind the engine air cleaner filter
assembly from the manufacturer.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine
and drivetrain (transmission and axle) in your
vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles (100 km), speeds
up to 50 or 55 mph (80 or 90 km/h) are desirable.
Brief full-throttle acceleration within the limits of
local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be
detrimental and should be avoided.
The engine oil installed in the engine at the factory is
a high-quality energy conserving type lubricant. Oil
changes should be consistent with anticipated
climate conditions under which vehicle operations
NOTE:
A new engine may consume some oil during its first
few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in
and not interpreted as a problem. Please check your
oil level with the engine oil indicator often during the
break-in period. Add oil as required.
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 auto
-
matic 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
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than
10 seconds at a time. Wait 10 to 15 seconds
before trying again.
WARNING!
Remember to disconnect the engine block
heater cord before driving. Damage to the
110-115 Volt electrical cord could cause
electrocution.
CAUTION!
Never use non-detergent oil or straight mineral
oil in the engine or damage may result.

(EPB)
Your vehicle is equipped with an EPB that offers
simple operation, and some additional features
that make the parking brake more convenient and
useful.
The parking brake is primarily intended to prevent
the vehicle from rolling while parked. Before
leaving the vehicle, make sure the parking brake is
applied. Also, be certain to leave the transmission
in PARK.
You can engage the parking brake in two ways:
Manually, by applying the parking brake switch.
Automatically, by enabling the Auto Park Brake
feature in the Customer Programmable
Features section of the Uconnect settings.
The parking brake switch is located on the
instrument panel to the left of the steering wheel
(below the headlamp switch).
Electric Park Brake Switch
To apply the parking brake manually, pull up on the
switch momentarily. You may hear a sound from
the back of the vehicle while the parking brake
engages. Once the parking brake is fully engaged,
the BRAKE telltale light in the instrument cluster
and an indicator on the switch will illuminate. If
your foot is on the brake pedal while you apply the
parking brake, you may notice a small amount of
brake pedal movement. The parking brake can be
applied even when the ignition switch is OFF but
the BRAKE telltale light will not illuminate,
however, it can only be released when the ignition
is in the ON/RUN position.
NOTE:
The EPB fault light will illuminate if the EPB switch
is held for longer than 20 seconds in either the
released or applied position. The light will extin
-
guish upon releasing the switch.
If the Auto Park Brake feature is enabled, the
parking brake will automatically engage whenever
the transmission is placed into PARK. If your foot is
on the brake pedal, you may notice a small amount
of brake pedal movement while the parking brake
is engaging.
The parking brake will release automatically when
the ignition is ON, the transmission is in DRIVE or
REVERSE, the driver seat belt is buckled, and an
attempt is made to drive away.
To release the parking brake manually, the ignition
switch must be in the ON/RUN position. Put your
foot on the brake pedal, then push the EPB switch
down momentarily. You may hear a sound from the
back of the vehicle while the parking brake
disengages. You may also notice a small amount of
movement in the brake pedal. Once the parking
brake is fully disengaged, the BRAKE telltale light
in the instrument cluster and the LED indicator on
the switch will extinguish.
NOTE:
When parking on a hill, it is important to turn the
front wheels toward the curb on a downhill grade
and away from the curb on an uphill grade. Apply
the parking brake before placing the gear selector
in PARK, otherwise the load on the transmission
locking mechanism may make it difficult to move
the gear selector out of PARK.
STARTING AND OPERATING
127
(Continued)
If exceptional circumstances should make it
necessary to engage the parking brake while the
vehicle is in motion, maintain upward pressure on
the EPB switch for as long as engagement is
desired. The BRAKE telltale light will illuminate,
and a continuous chime will sound. The rear stop
lamps will also be illuminated automatically while
the vehicle remains in motion.
To disengage the parking brake while the vehicle is
in motion, release the switch. If the vehicle is
brought to a complete stop using the parking
brake, when the vehicle reaches approximately
3 mph, (5 km/h) the parking brake will remain
engaged.
In the unlikely event of a malfunction of the EPB
system, a yellow EPB fault light will illuminate. This
may be accompanied by the BRAKE telltale light
flashing. In this event, urgent service of the EPB
system is required. Do not rely on the parking
brake to hold the vehicle stationary.

Any single Auto Park Brake application can be
bypassed by pushing the EPB switch to the release
position while the transmission is placed in PARK.
WARNING!
Never use the PARK position as a substitute
for the parking brake. Always apply the
parking brake fully when parked to guard
against vehicle movement and possible injury
or damage.
When exiting the vehicle, always turn the igni
-
tion OFF, secure the key fob, and lock your
vehicle.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing chil

dren to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured.
Children should be warned not to touch the
parking brake, brake pedal or the gear
selector.
Do not leave the key fob in or near the vehicle,
or in a location accessible to children, and do
not leave a vehicle equipped with Keyless
Enter ‘n Go™ in the ON/RUN position. A child
could operate power windows, other controls,
or move the vehicle.
Be sure the parking brake is fully disengaged
before driving; failure to do so can lead to
brake failure and a collision.
Always fully apply the parking brake when
leaving your vehicle, or it may roll and cause
damage or injury. Also be certain to leave the
transmission in PARK. Failure to do so may
allow the vehicle to roll and cause damage or
injury.
CAUTION!
If the Brake System Warning Light remains on
with the parking brake released, a brake system
malfunction is indicated. Have the brake system
serviced by an authorized dealer immediately.

We recommend having your brakes serviced by an
authorized dealer. You should only make repairs
for which you have the knowledge and the right
equipment. You should only enter Brake
Maintenance Mode during brake service.
When servicing your rear brakes, it may be
necessary for you or your technician to push the
rear piston into the rear caliper bore. With the EPB
system, this can only be done after retracting the
EPB actuator. Fortunately, actuator retraction can
be done easily by entering the Brake Maintenance
Mode through the Uconnect Settings in your
vehicle. This menu-based system will guide you
through the steps necessary to retract the EPB
actuator in order to perform rear brake service.
Maintenance Mode has requirements that must be
met in order to be activated:
The vehicle must be at a standstill.
The parking brake must be unapplied.
The transmission must be in PARK or NEUTRAL.
While in Maintenance Mode, the EPB fault lamp
will flash continuously while the ignition is ON.

Ensure the vehicle is at a standstill.
Press the brake pedal with moderate force.
Apply the EPB Switch.
AUTOMATIC TRANSMISSION
You must press and hold the brake pedal while
shifting out of PARK.
WARNING!
You can be badly injured working on or around a
motor vehicle. Do only that service work for
which you have the knowledge and the right
equipment. If you have any doubt about your
ability to perform a service job, take your vehicle
to a competent mechanic.
WARNING!
Never use the PARK (P) position as a substi
-
tute for the parking brake. Always apply the
parking brake fully when exiting the vehicle to
guard against vehicle movement and possible
injury or damage.
Your vehicle could move and injure you and
others if it is not in PARK. Check by trying to
move the transmission gear selector out of
PARK with the brake pedal released. Make
sure the transmission is in PARK before
exiting the vehicle.
The transmission may not engage PARK if the
vehicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and
verify that the transmission gear position indi
-
cator solidly indicates PARK without blinking.
Ensure that the vehicle is completely stopped,
and the PARK position is properly indicated,
before exiting the vehicle.
It is dangerous to shift out of PARK or
NEUTRAL (N) if the engine speed is higher
than idle speed. If your foot is not firmly
pressing the brake pedal, the vehicle could
accelerate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and your
foot is firmly pressing the brake pedal.
WARNING!
Unintended movement of a vehicle could
injure those in or near the vehicle. As with all
vehicles, you should never exit a vehicle while
the engine is running. Before exiting a vehicle,
always come to a complete stop, then apply
the parking brake, shift the transmission into
PARK, and turn the ignition OFF. When the
ignition is in the OFF position, the transmis
-
sion is locked in PARK, securing the vehicle
against unwanted movement.
When exiting the vehicle, always make sure
the ignition is in the OFF position, remove the
key fob from the vehicle, and lock the vehicle.
Never leave children alone in a vehicle, or with

RANSMISSION
The transmission is controlled using a rotary
electronic gear selector located on the center
console. The transmission gear range (PRND) is
displayed both above the gear selector and in the
instrument cluster. To select a gear range, simply
rotate the gear selector. You must press the brake
pedal to shift the transmission out of PARK (or
NEUTRAL, when the vehicle is stopped or moving at
low speeds). To shift past multiple gear ranges at
once (such as PARK to DRIVE), simply rotate the
gear selector to the appropriate detent. Select the
DRIVE range for normal driving.
NOTE:
In the event of a mismatch between the gear
selector position and the actual transmission gear
(for example, driver selects PARK while driving),
the position indicator will blink continuously until
the selector is returned to the proper position, or
the requested shift can be completed.
The electronically controlled transmission adapts
its shift schedule based on driver inputs, along
with environmental and road conditions. The
transmission electronics are self-calibrating;
therefore, the first few shifts on a new vehicle may
be somewhat abrupt. This is a normal condition,
and precision shifts will develop within a few
hundred miles (kilometers).
Only shift from DRIVE to PARK or REVERSE when
the accelerator pedal is released and the vehicle is
stopped. Be sure to keep your foot on the brake
pedal when shifting between these gears.
The transmission gear selector has only PARK,
REVERSE, NEUTRAL, and DRIVE positions. Manual
downshifts can be made using the steering wheel
mounted paddle shifters. Pulling the -/+ switches
(on the steering wheel) while in the DRIVE position
will select the highest available transmission gear,
and will display that gear limit in the instrument
cluster as 1, 2, 3, etc. Some models will display
both the selected gear limit, and the actual current
gear, while in AutoStick mode.
CAUTION!
Damage to the transmission may occur if the
following precautions are not observed:
Shift into or out of PARK or REVERSE (R) only
after the vehicle has come to a complete stop.
Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE (D) when the engine is
above idle speed.
Before shifting into any gear, make sure your
foot is firmly pressing the brake pedal.

ating. This is especially important when the engine
is cold.
PARK (P)
This range supplements the parking brake by
locking the transmission. The engine can be
started in this range. Never attempt to use PARK
while the vehicle is in motion. Apply the parking
brake when exiting the vehicle in this range.
When parking on a hill, apply the parking brake
before shifting the transmission to PARK. As an
added precaution, turn the front wheels toward the
curb on a downhill grade and away from the curb
on an uphill grade.
When exiting the vehicle, always:
Apply the parking brake.
Shift the transmission into PARK.
Turn the ignition OFF.
Remove the key fob from the vehicle.
NOTE:
On four-wheel drive vehicles be sure that the
transfer case is in a drive position.
The following indicators should be used to ensure
that you have properly engaged the transmission
into the PARK position:
When shifting into PARK, rotate the shifter all
the way counterclockwise until the indicator
displays PARK.
Look at the transmission gear position display
and verify that it indicates the PARK position (P),
and is not blinking.
With the brake pedal released, verify that the
gear selector will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward.
Shift into REVERSE only after the vehicle has come
to a complete stop.
NEUTRAL (N)
Use this range when the vehicle is standing for
prolonged periods with the engine running. Apply
the parking brake and shift the transmission into
PARK (P) if you must exit the vehicle.
CAUTION!
Before moving the transmission gear selector
out of PARK, you must start the engine, and
also press the brake pedal. Otherwise,
damage to the gear selector could result.
DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as
this can damage the drivetrain.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing
traffic or road conditions. You might lose control
of the vehicle and have a collision.

132
STARTING AND OPERATING
DRIVE (D)
This range should be used for most city and
highway driving. It provides the smoothest upshifts
and downshifts, and the best fuel economy. The
transmission automatically upshifts through all
forward gears.
When frequent transmission shifting occurs (such
as when operating the vehicle under heavy loading
conditions, in hilly terrain, traveling into strong
head winds, or while towing a heavy trailer), use
the AutoStick shift control to select a lower gear
page 133. Under these conditions, using a lower
gear will improve performance and extend
transmission life by reducing excessive shifting
and heat build-up.
During cold temperatures, transmission operation
may be modified depending on engine and
transmission temperature as well as vehicle
speed. This feature improves warm-up time of the
engine and transmission to achieve maximum
efficiency. Engagement of the torque converter
clutch is inhibited until the transmission fluid is
warm. Normal operation will resume once the
transmission temperature has risen to a suitable
level.
Transmission Limp Home Mode
Transmission function is monitored electronically
for abnormal conditions. If a condition is detected
that could result in transmission damage,
Transmission Limp Home Mode is activated. In this
mode, the transmission may operate only in
certain gears, or may not shift at all. Vehicle
performance may be severely degraded and the
engine may stall. In some situations, the
transmission may not re-engage if the engine is
turned off and restarted. The Malfunction Indicator
Light (MIL) may be illuminated. A message in the
instrument cluster will inform the driver of the
more serious conditions, and indicate what actions
may be necessary.
In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:
NOTE:
In cases where the instrument cluster message
indicates the transmission may not re-engage after
engine shutdown, perform this procedure only in a
desired location (preferably, at an authorized
dealer).
1. Stop the vehicle.
2. Shift the transmission into PARK (P), if
possible. If not, shift the transmission to
NEUTRAL (N).
3. Push and hold the ignition switch until the
engine turns off.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the
problem is no longer detected, the
transmission will return to normal operation.
NOTE:
Even if the transmission can be reset, we
recommend that you visit an authorized dealer at
your earliest possible convenience. An authorized
dealer has diagnostic equipment to assess the
condition of your transmission.
If the transmission cannot be reset, authorized
dealer service is required.
CAUTION!
Towing the vehicle, coasting, or driving for any
other reason with the transmission in NEUTRAL
can cause severe transmission damage.

AutoStick — If Equipped
AutoStick is a driver-interactive transmission
feature providing manual shift control, giving you
more control of the vehicle. AutoStick allows you to
maximize engine braking, eliminate undesirable
upshifts and downshifts, and improve overall
vehicle performance. This feature can also provide
you with more control during passing, city driving,
cold slippery conditions, mountain driving, trailer
towing, and many other situations.
AutoStick Paddle Shifters
Operation
To activate AutoStick mode, tap one of the paddle
shifters on the steering wheel. Tapping the (-)
paddle shifters to enter AutoStick mode will
downshift the transmission to the next lower gear,
while tapping (+) to enter AutoStick mode will
retain the current gear. The current transmission
gear will be displayed in the instrument cluster.
In AutoStick mode, you can use the paddle shifters,
to manually shift the transmission. Tapping the (-)
paddle shifters, will downshift the transmission to
the next lower gear. Tapping the (+) paddle
shifters, will upshift the transmission to the next
highest gear.
NOTE:
The paddle shifters (if equipped) may be disabled
(or re-enabled, as desired) using the Uconnect
Programmable Settings.
In AutoStick mode, the transmission will shift up or
down when (+/-) is manually selected by the driver,
unless an engine lugging or overspeed condition
would result. It will remain in the selected gear
until another upshift or downshift is chosen, except
as follows.
The transmission will automatically downshift
as the vehicle slows (to prevent engine lugging)
and will display the current gear.
The transmission will automatically downshift to
FIRST gear when coming to a stop. After a stop,
the driver should manually upshift (+) the trans
-
mission as the vehicle is accelerated.
You can start out, from a stop, in FIRST or
SECOND gear. Tapping (+) at a stop will allow
starting in SECOND gear. Starting out in
SECOND gear can be helpful in snowy or icy
conditions.
If a requested downshift would cause the
engine to over-speed, that shift will not occur.
The system will ignore attempts to upshift at too
low of a vehicle speed.
Holding the (-) paddle pressed, will downshift
the transmission to the lowest gear possible at
the current speed.
Transmission shifting will be more noticeable
when AutoStick is enabled.
The system may revert to automatic shift mode
if a fault or overheat condition is detected. The
vehicle will force an upshift, but it will stay in
AutoStick mode.
To disengage AutoStick mode, push and hold the
(+) paddle shifters until "D" is once again indicated
in the instrument cluster. You can shift in or out of
AutoStick mode at any time without taking your
foot off the accelerator pedal.
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing a collision or personal injury.

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 OPERATING
135
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type, and
circumference on each wheel. Any difference will
adversely affect performance and function of 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.

4WD HI
This is the default operating range for daily use.
N (NEUTRAL)
This range disengages the driveline from the
powertrain. It is used for towing your 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 delivered 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).

The Quadra-Trac II System features two torque
transfer couplings. The couplings include an
Electronic Limited-Slip Differential (ELSD) rear axle
and the Quadra-Trac II transfer case. The ELSD
axle is fully automatic and requires no driver input
to operate. Under normal driving conditions, the
unit functions as a standard axle, balancing torque
evenly between left and right wheels. 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 automatically 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 shifting information, preceding this
section, for shifting this system.

Your vehicle may be equipped with an electronic
disconnecting stabilizer/sway bar. This system
allows greater front suspension travel in off-road
situations.
This system is controlled by the SWAY BAR switch
located on the instrument panel (to the right of the
gear selector).
SWAY BAR Switch
Push the SWAY BAR switch to activate the system.
Push the switch again to deactivate the system.
The Sway Bar Indicator Light (located in the
instrument cluster) will illuminate when the bar is
disconnected. The Sway Bar Indicator Light will
flash during activation transition, or when
activation conditions are not met.
STARTING AND OPERATING
137
The stabilizer/sway bar should remain in on-road
mode during normal driving conditions.
To disconnect the stabilizer/sway bar, shift to 4WD
LOW and push the SWAY BAR switch to obtain the
page 134. The Sway Bar
Indicator Light will flash until the stabilizer/sway
bar has been fully disconnected.
NOTE:
The stabilizer/sway bar may be torque locked due
to left and right suspension height differences.
This condition is due to driving surface differences
or vehicle loading. In order for the stabilizer/sway
bar to disconnect/reconnect, the right and left
halves of the bar must be aligned. This alignment
may require that the vehicle be driven onto level
ground or rocked from side to side.
To return to on-road mode, push the SWAY BAR
switch again.

WARNING!
Ensure the stabilizer/sway bar is reconnected
before driving on hard surfaced roads or at
speeds above 18 mph (29 km/h); a
disconnected stabilizer/sway bar may contribute
to the loss of vehicle control, which could result
in serious injury. Under certain circumstances,
the front stabilizer/sway bar enhances vehicle
stability and assists with vehicle control. The
system monitors vehicle speed and will attempt
to reconnect the stabilizer/sway bar at speeds
over 18 mph (29 km/h). This is indicated by a
flashing or solid Sway Bar Indicator Light. Once
vehicle speed is reduced below 14 mph
(22 km/h), the system will once again attempt to
return to off-road mode.
WARNING!
If the stabilizer/sway bar will not return to
on-road mode, the Sway Bar Indicator Light will
flash in the instrument cluster and vehicle
stability may be reduced. Do not attempt to drive
the vehicle over 18 mph (29 km/h). Driving
faster than 18 mph (29 km/h) with a
disconnected stabilizer/sway bar may contribute
to the loss of vehicle control, which could result
in serious injury.

STARTING AND OPERATING
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
-

The Quadra-Lift Air Suspension system provides
full time load leveling capability along with the
benefit of vehicle height adjustment by a toggle
switch. The vehicle will automatically raise and
lower the ride height to adapt to the appropriate
driving conditions. At higher speeds, the vehicle
will lower to an aerodynamic ride height and when
operating in off-road modes, the vehicle will raise
the ride height accordingly. The buttons near the
terrain switch in the center console area can be
used to set preferred ride height to match the
appropriate conditions.
