supplement the power brake system
under conditions where the driver has
quickly and forcefully applied the
brake pedal in an attempt to quickly
stop or slow down the vehicle. The
stability system hydraulic brake
control module increases brake
pressure at each corner of the vehicle
until the ABS activates. Minor brake
pedal pulsation or pedal movement
during this time is normal and the
driver should continue to apply the
brake pedal as the driving situation
dictates. The brake assist feature will
automatically disengage when the
brake pedal is released or brake pedal
pressure is quickly decreased.Hill Start Assist (HSA)
This vehicle has a Hill Start Assist
(HSA) feature, which may be useful
when the vehicle is stopped on a
grade sufficient enough to activate
HSA. This feature is designed to
prevent the vehicle from rolling, either
forward or rearward, during vehicle
drive off. After the driver completely
stops and holds the vehicle in a
complete standstill on a grade, HSA
will be automatically activated. During
the transition period between when
the driver releases the brake pedal and
starts to accelerate to drive off on a
grade, HSA holds the braking pressure
for a maximum of two seconds to
ensure that there is no rolling. The
brakes will automatically release when
the accelerator pedal is applied within
the two-second window. It will not
activate if the vehicle is in a drive gear
and facing downhill, or if the vehicle
is facing uphill and in R (Reverse).
Ride Control Systems
Traction Control/Electronic
Stability Control
System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak®, an
electronic stability control system.
These systems help limit wheel slip
and assist the driver in maintaining
control, especially on slippery road
conditions.
TCS activates if it senses that any of
the drive wheels are spinning or
beginning to lose traction. On an
All-Wheel-Drive (AWD) vehicle, the
system will operate if it senses that
any of the wheels are spinning or
beginning to lose traction. When this
happens, TCS applies the brakes to the
spinning wheels and reduces engine
power to limit wheel spin.
StabiliTrak activates when the system
senses a discrepancy between the
intended path and the direction the
vehicle is actually traveling.
StabiliTrak selectively applies braking

pressure at any one of the vehicle's
brakes to help steer the vehicle in the
direction which you are steering.
If cruise control is being used and
traction control or StabiliTrak begins
to limit wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road conditions
allow.
Both systems come on automatically
when the vehicle is started and begins
to move. The systems may be heard or
felt while they are operating or while
performing diagnostic checks. This is
normal and does not mean there is a
problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary to
turn TCS off if the vehicle gets stuck
in sand, mud, ice, or snow. SeeIf the
Vehicle Is Stuck 0173 and “Turning
the Systems Off and On ”later in this
section.
The indicator light for both systems is
in the instrument cluster. This
light will:
. Flash when TCS is limiting
wheel spin.
. Flash when StabiliTrak is
activated.
. Turn on and stay on when either
system is not working.
If either system fails to turn on or to
activate, a message displays in the
Driver Information Center (DIC),
and
dcomes on and stays on to
indicate that the system is inactive
and is not assisting the driver in
maintaining control. The vehicle is
safe to drive, but driving should be
adjusted accordingly.
If
dcomes on and stays on:
1. Stop the vehicle. 2. Turn the engine off and wait
15 seconds.
3. Start the engine.
Drive the vehicle. If
dcomes on and
stays on, the vehicle may need more
time to diagnose the problem. If the
condition persists, see your dealer.
Turning the Systems Off and On
The button for TCS and StabiliTrak is
on the center stack.

Magnetic Ride Control
The Magnetic Ride Control monitors
the suspension system.
Based on road conditions, steering
wheel angle, and vehicle speed, the
system automatically adjusts to
provide the best handling while
providing a smooth ride. The Tour and
Sport Modes will feel similar on a
smooth road.
Tour : Use for normal city and
highway driving. This setting provides
a smooth, soft ride.
Sport : Use where road conditions or
personal preference demand more
control. This setting provides more
“feel,” or response to road conditions. The vehicle is normally in Tour Mode.
Sport Mode is engaged when the shift
lever is placed in M (Manual Mode).
When the shift lever is placed in D
(Drive) the system will revert back to
Tour Mode.
The Driver Information Center (DIC)
briefly displays the appropriate
message on vehicle startup or when a
new mode is selected. See
Ride Control
System Messages 0141.
Limited-Slip Rear Axle
Vehicles with a limited-slip rear axle
can give more traction on snow, mud,
ice, sand or gravel. When traction is
low, this feature allows the drive
wheel with the most traction to move
the vehicle. The limited-slip rear axle
also gives the driver enhanced control
when cornering hard or completing a
maneuver, such as a lane change.

DRIVING AND OPERATING 191
Automatic Level Control
The automatic level control rear
suspension is available on some
vehicles.
This type of level control is fully
automatic and will provide a better
leveled riding position as well as
better handling under a variety of
passenger and loading conditions. An
air compressor connected to the rear
air springs will raise or lower the rear
of the vehicle to maintain proper
vehicle height. The system is activated
when the engine is running and will
automatically adjust vehicle height
thereafter. The system may exhaust
(lower vehicle height) for up to
10 minutes after the engine has been
turned off. You may hear the air
compressor operating when the height
is being adjusted; this is normal.If the compressor runs often for
longer than one minute within the
same trip and the vehicle remains low
in the rear, see your dealer for service.
If the vehicle is not used for several
weeks, the rear of the vehicle may
look low. When the engine is started,
the vehicle will return to the proper
height.
If a weight-distributing hitch is being
used, it is recommended to allow the
air springs to inflate, thereby leveling
the vehicle prior to adjusting the
hitch.
Cruise Control
{Warning
Cruise control can be dangerous
where you cannot drive safely at a
steady speed. Do not use cruise
control on winding roads or in
heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could
lose control. Do not use cruise
control on slippery roads.
With cruise control, a speed of about
40 km/h (25 mph) or more can be
maintained without keeping your foot
on the accelerator. Cruise control does
not work at speeds below about
40 km/h (25 mph).

Selecting the Follow Distance
When a slower moving vehicle is
detected ahead within the selected
following gap, ACC will adjust the
vehicle's speed and attempt to
maintain the follow distance gap
selected.
Press
[on the steering wheel to
adjust the following gap. Each press
cycles the gap button through three
settings: Far, Medium, or Near.
When pressed, the current gap setting
displays briefly on the instrument
cluster and HUD. The gap setting will
be maintained until it is changed.
Since each gap setting corresponds to
a following time (Far, Medium,
or Near), the following distance will
vary based on vehicle speed. The
faster the vehicle speed, the further
back your vehicle will follow a vehicle
detected ahead. Consider traffic and
weather conditions when selecting the
following gap. The range of selectable
gaps may not be appropriate for all
drivers and driving conditions. Changing the gap setting
automatically changes the alert timing
sensitivity (Far, Medium, or Near) for
the Forward Collision Alert (FCA)
feature. See
Forward Collision Alert
(FCA) System 0206.
Alerting the Driver
If ACC is engaged, driver action may
be required when ACC cannot apply
sufficient braking because of
approaching a vehicle too rapidly.
When this condition occurs, the
collision alert symbol on the HUD will
flash on the windshield. Either eight
beeps will sound from the front,
or both sides of the Safety Alert Seat
will pulse five times. See “Collision/
Detection Systems” underVehicle
Personalization 0144.
See Defensive Driving 0168. Approaching and Following a
Vehicle
The vehicle ahead indicator is in the
instrument cluster and HUD display.
The vehicle ahead indicator only
displays when a vehicle is detected in
your vehicle’s path moving in the
same direction.
If this indicator is not displaying, ACC
will not respond to or brake to
vehicles ahead.
ACC automatically slows the vehicle
down and adjusts vehicle speed to
follow the vehicle in front at the
selected follow gap. The vehicle speed
increases or decreases to follow the
vehicle in front of you, but will not
exceed the set speed. It may apply
limited braking, if necessary. When
braking is active, the brake lights will
come on. The automatic braking may

Assistance Systems for
Driving
If equipped, when driving the vehicle
in a forward gear, Forward Collision
Alert (FCA), Lane Departure Warning
(LDW), Side Blind Zone Alert (SBZA),
and/or the Forward Automatic Braking
(FAB) System can help to avoid a
crash or reduce crash damage.
Forward Collision Alert
(FCA) System
If equipped, the FCA system may help
to avoid or reduce the harm caused by
front-end crashes. When approaching
a vehicle ahead too quickly, FCA
provides a red flashing alert on the
windshield and rapidly beeps or pulses
the driver seat. FCA also lights an
amber visual alert if following another
vehicle much too closely.
FCA detects vehicles within a distance
of approximately 60 m (197 ft) and
operates at speeds above 40 km/h
(25 mph). If the vehicle has Adaptive
Cruise Control (ACC), it can detect
vehicles to distances of approximately 110 m (360 ft) and operates at all
speeds. See
Adaptive Cruise
Control 0194.
{Warning
FCA is a warning system and does
not apply the brakes. When
approaching a slower-moving or
stopped vehicle ahead too rapidly,
or when following a vehicle too
closely, FCA may not provide a
warning with enough time to help
avoid a crash. It also may not
provide any warning at all. FCA
does not warn of pedestrians,
animals, signs, guardrails, bridges,
construction barrels, or other
objects. Be ready to take action and
apply the brakes. See Defensive
Driving 0168.
FCA can be disabled with the FCA
steering wheel control, or if your
vehicle is equipped with Adaptive
Cruise Control (ACC), through vehicle
personalization. See the “Auto
