StabiliTrak®System
The vehicle has an electronic
stability control system called
StabiliTrak. It is an advanced
computer controlled system that
assists with directional control of the
vehicle in difficult driving conditions.
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.
When the system activates, this
warning light flashes on the
instrument panel. A noise may be
heard or a vibration may be felt in
the brake pedal. This is normal.
Continue to steer the vehicle in the
intended direction.
If there is a problem detected with
StabiliTrak, the appropriate
message displays on the Driver
Information Center (DIC) and the
TCS/StabiliTrak warning light comes
on in the instrument panel cluster.
When this message and light
display, the system is not
operational. Driving should be
adjusted accordingly. See Driver
Information Center (DIC) on
page 5‑27 andTraction Control
System (TCS)/StabiliTrak

9-34 Driving and Operating
Ending Cruise Control
There are three ways to end cruise
control:
.Step lightly on the brake pedal.
.Press*.
.PressJ.
Erasing Speed Memory
The cruise control set speed is
erased from memory if
Jis
pressed or if the ignition is
turned off.
Adaptive Cruise Control
For vehicles with Adaptive Cruise
Control (ACC), it allows the driver to
select the cruise control set speed
and following gap. Read this entire
section before using this system.
The following gap is the distance
between your vehicle and a
vehicle-detected directly ahead in
your path. If no vehicle is detected
in your path, ACC works like regular
cruise control. ACC uses camera and radar sensors. See
Radio
Frequency Statement on
page 13‑15 for information
regarding Part 15 of the Federal
Communications Commission (FCC)
rules and Industry Canada
Standards RSS-GEN/210/220/310.
If a vehicle is detected in your path,
ACC can apply acceleration or
limited, moderate braking to
maintain the selected following gap.
To disengage ACC, apply the brake.
If ACC is controlling your vehicle
speed when the traction control
system (TCS) activates, the ACC
will automatically disengage. See
Traction Control System (TCS) on
page 9‑28. When road conditions
allow ACC to be safely used, the
ACC can be turned back on.
{WARNING
ACC has limited braking ability
and may not have time to slow
the vehicle down enough to avoid
(Continued)
WARNING (CONTINUED)
a collision with another vehicle
you are following. This can occur
when vehicles suddenly slow or
stop ahead, enter your lane,
or cross the vehicle’s path. Also
see“Alerting the Driver” in this
section. Complete attention is
always required while driving and
you should be ready to take
action and apply the brakes. See
Defensive Driving on page 9‑3.
{WARNING
Adaptive Cruise Control will not
detect or brake for children,
pedestrians, animals, or other
objects.

9-38 Driving and Operating
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.
.A temporary condition prohibits
ACC from operating. See
Vehicle Messages on page 5‑34.
.A malfunction is detected in the
system. SeeVehicle Messages
on page 5‑34.
When any of these conditions occur,
the collision alert symbol on the
HUD (if equipped) 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 on page 5‑44.
See Defensive Driving on page 9‑3.
Approaching and Following a
Vehicle
The vehicle ahead symbol is located
in the HUD display.
The vehicle ahead symbol only
displays when a vehicle is detected
in your vehicle’s path.
If this symbol 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 feel or sound different
than if the brakes were applied
manually. This is normal.
Stationary or Very Slow-Moving
Objects
{WARNING
Adaptive Cruise Control (ACC)
may not detect and react to
stopped or slow-moving vehicles
ahead of you. For example, the
system will not brake for a vehicle
that it has never detected moving.
This can occur when a detected
vehicle changes lanes at an
intersection or in stop-and-go
traffic and then a stopped or
slow-moving vehicle appears.
Your vehicle may not stop and
could cause a crash. Use caution

Driving and Operating 9-39
WARNING (CONTINUED)
when using ACC. Your complete
attention is always required while
driving and you should be ready
to take action and apply the
brakes.
ACC Automatically Disengages
ACC may automatically disengage
and the driver will need to manually
apply the brakes to slow the
vehicle when:
.The sensors are blocked.
.There is no traffic or other
objects to detect.
.There is a fault in the system.
The ACC active symbol will not be
displayed when ACC is no longer
active. Notification to Resume ACC
ACC will maintain a follow gap
behind a detected vehicle and slow
your vehicle to a stop behind that
vehicle.
If the vehicle ahead has driven
away and ACC has not resumed,
the vehicle ahead symbol will flash
as a reminder. In addition, the left
and right sides of the Safety Alert
Seat will pulse three times, or three
beeps will sound. See
”Alert Type”
and “Go Notifier” in“Collision/
Detection Systems” underVehicle
Personalization on page 5‑44.
When the vehicle ahead drives
away, press RES+ or the
accelerator pedal to resume cruise
control. If stopped for more than
two minutes or if the driver door is
opened and the driver safety belt is
unbuckled, the ACC automatically
applies the electric parking brake to
hold the vehicle. The electric
parking brake status light will turn
on. See Electric Parking Brake on
page 9‑26. To resume ACC and release the electric parking brake,
press the accelerator pedal and
then RES+.
{WARNING
If ACC has stopped the vehicle,
and if ACC is disengaged, turned
off, or canceled, the vehicle will
no longer be held at a stop. The
vehicle can move. When ACC is
holding the vehicle at a stop,
always be prepared to manually
apply the brakes.
{WARNING
Leaving the vehicle without
placing it in P (Park) can be
dangerous. Do not leave the
vehicle while it is being held at a
stop by ACC. Always place the
vehicle in P (Park) and turn off
the ignition before leaving the
vehicle.

Driving and Operating 9-41
ACC may detect a vehicle that is
not in your lane and apply the
brakes.
ACC may occasionally provide an
alert and/or braking that is
considered unnecessary. It could
respond to vehicles in different
lanes, signs, guardrails, and other
stationary objects when entering or
exiting a curve. This is normal
operation. The vehicle does not
need service.Other Vehicle Lane Changes
ACC will not detect a vehicle ahead
until it is completely in the lane. The
brakes may need to be manually
applied.
Using ACC on Hills and When
Towing a Trailer
Do not use ACC when driving on
steep hills or when towing a trailer.
The performance of ACC when
driving on hills and when towing a
trailer depends on the vehicle
speed, vehicle load, traffic
conditions, and steepness of the
hills. It may not detect a vehicle in
the lane while driving on hills. When
going up steep hills, the accelerator
pedal may need to be pressed to
maintain the vehicle speed. When
going downhill, especially when
towing a trailer, the brakes may
need to be applied by the driver to
slow the vehicle down. If the brakes
are applied, ACC disengages.
Disengaging ACC
There are three ways to
disengage ACC:
.Step lightly on the brake pedal.
.Press*.

windshield washer system
and paint.
Brakes
This vehicle has disc brakes. Disc
brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads are needed.
The sound can come and go or be
heard all the time the vehicle is
moving, except when applying the
brake pedal firmly.
{WARNING
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
a crash. When the brake wear
warning sound is heard, have the
vehicle serviced.Notice:
Continuing to drive with
worn-out brake pads could result
in costly brake repair.
Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.
Properly torqued wheel nuts are
necessary to help prevent brake
pulsation. When tires are rotated,
inspect brake pads for wear and
evenly tighten wheel nuts in the
proper sequence to torque
specifications in Capacities and
Specifications on page 12‑2.
Brake linings should always be
replaced as complete axle sets.Brake Pedal Travel
See your dealer if the brake pedal
does not return to normal height,
or if there is a rapid increase in
pedal travel. This could be a sign
that brake service might be
required.
Brake Adjustment
Every time the brakes are applied,
with or without the vehicle moving,
the brakes adjust for wear.
Replacing Brake System Parts
The braking system on a vehicle is
complex. Its many parts have to be
of top quality and work well together
if the vehicle is to have really good
braking. The vehicle was designed
and tested with top-quality brake
parts. When parts of the braking
system are replaced, be sure to get
new, approved replacement parts.
If this is not done, the brakes might
not work properly. For example,
installing disc brake pads that are
wrong for the vehicle, can change
the balance between the front and
rear brakes —for the worse. The
braking performance expected can
change in many other ways if the
wrong replacement brake parts are
installed.
