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. When this
happens, TCS applies the brakes to
the spinning wheels and reduces
engine power to limit wheel spin.
StabiliTrak activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak selectively applies
braking pressure to any one of the vehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
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.
See
If the Vehicle Is Stuck on
page 9-10 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.

9-38 Driving and Operating
Cruise Control
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).
{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.If equipped with a manual
transmission, the cruise control will
remain active when the gears are
shifted. The cruise is deactivated if
the clutch is pressed for several
seconds.
If the StabiliTrak
®system begins to
limit wheel spin while using cruise
control, the cruise control
automatically disengages. See
Traction Control/Electronic Stability
Control on page 9-34. If a collision
alert occurs when cruise control is
activated, cruise control is
disengaged. See Forward Collision
Alert (FCA) System on page 9-54.
When road conditions allow you to
safely use it again, cruise control
can be turned back on.
If the brakes are applied, cruise
control disengages.
J(On/Off): Press to turn the
system on and off. A white cruise
control indicator appears in the
instrument cluster when cruise is
turned on.
+RES (Resume/Accelerate): If
there is a set speed in memory,
press the control up briefly to
resume that speed or hold to
accelerate. If cruise control is
already active, use to increase

If the cruise control is set at a
desired speed and then the brakes
are applied or
*is pressed, the
cruise control is disengaged without
erasing the set speed from memory.
Once the vehicle speed reaches
about 40 km/h (25 mph) or more,
briefly press +RES up to the first
detent. The vehicle returns to the
previous set speed. Increasing Speed While Cruise
Control is at a Set Speed
If the cruise control system is
already activated:
.Press and hold +RES up until
the desired speed is reached,
then release it.
.To increase vehicle speed in
small increments, briefly press
+RES up to the first detent. For
each press, the vehicle goes
about 1 km/h (1 mph) faster.
.To increase vehicle speed in

vehicle down.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster on page 5-10. The increment value
used depends on the units
displayed.
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase the vehicle speed. When
you take your foot off the pedal, the
vehicle will slow down to the
previously set cruise speed. While
pressing the accelerator pedal or
shortly following the release to
override cruise control, briefly
applying the SET–
control will result
in cruise control set to the current
vehicle speed.
Using Cruise Control on Hills
How well cruise control will work on
hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain the
vehicle speed. When going
downhill, the cruise control system
may automatically brake to slow the
vehicle down. Also, you may have to brake or shift to a lower gear to
keep the vehicle speed down. If the
brake pedal is applied, cruise
control will disengage.
Ending Cruise Control
There are five ways to end cruise
control:
.Step lightly on the brake pedal
(manual and automatic
transmissions).
.Press the clutch pedal for
several seconds or shift to
Neutral (manual transmissions).
.Shift the transmission to
N (Neutral).
.Press*.
.PressJ.

Adaptive Cruise Control
If equipped 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 following
time between your vehicle and a
vehicle detected directly ahead in
your path moving in the same
direction. If no vehicle is detected in
your path, ACC works like regular
cruise control. ACC uses camera
and radar sensors. SeeRadio
Frequency Statement on
page 13-12.
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) or the StabiliTrak
system activates, the ACC may automatically disengage. See
Traction Control/Electronic Stability
Control on page 9-34. When road
conditions allow ACC to be safely
used, the ACC can be turned
back on.
ACC will not engage if the TCS or
StabiliTrak is disabled.
{Warning
ACC has limited braking ability
and may not have time to slow
the vehicle down enough to avoid
a collision with another vehicle
you are following. This can occur
when vehicles suddenly slow or
stop ahead, or enter your lane.
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.
Do not use Adaptive Cruise
Control when:
.On winding and hilly roads or
when the sensors are
blocked by snow, ice, or dirt.
The system may not detect a
vehicle ahead. Keep the
entire front of the vehicle
clean.
.Visibility is low, such as in
fog, rain, or snow conditions.
Adaptive Cruise Control
performance is limited under
these conditions.
.On slippery roads where fast
changes in tire traction can
cause excessive wheel slip.

The ACC indicator displays in the
instrument cluster and Head-Up
Display (HUD). When the ACC is
active, the indicator will be lit green.
Be mindful of speed limits,
surrounding traffic speeds, and
weather conditions when selecting
the set speed.
Resuming a Set Speed
If the ACC is set at a desired speed
and then the brakes are applied, the
ACC is disengaged without erasing
the set speed from memory.
To begin using ACC again, press
+RES up briefly on the steering
wheel. The vehicle returns to the

a Set Speed
If ACC is already activated, do one
of the following:
.Use the accelerator to get to the
higher speed. Press SET–
down.
Release the control and the
accelerator pedal. The vehicle
will now cruise at the higher
speed.
When the accelerator pedal is
pressed, ACC will not brake
because it is overridden.
A warning message will appear
on the Driver Information Center
(DIC) and the Head-Up Display
(HUD). See Cruise Control
Messages on page 5-33.
.Press and hold +RES up until
the desired set speed appears
on the display, then release it.
.To increase vehicle speed in
small increments, press +RES
up to the first detent. For each
press, the vehicle goes 1 km/h
(1 mph) faster.
.To increase vehicle speed in
larger increments, press +RES
up to the second detent. For
each press, the vehicle speed
increases to the next 5 km/h
(5 mph) mark on the
speedometer.
When it is determined that there is
no vehicle ahead inside the selected
following gap, then the vehicle
speed will increase to the set speed.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster on
page 5-10. The increment value
used depends on the units
displayed.
Reducing Speed While ACC is at a

Approaching and Following a
Vehicle
The vehicle ahead symbol is in the
instrument cluster and HUD display.
The vehicle ahead symbol only
displays when a vehicle is detected
in your vehicle’s path moving in the
same direction.
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 brakelamps 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 may not brake for a
vehicle it has never detected
moving. This can occur in
stop-and-go traffic or when a
vehicle suddenly appears due to
a vehicle ahead changing lanes.
Your vehicle may not stop and
could cause a crash. Use caution
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.
.The Traction Control System
(TCS) or StabiliTrak system has
activated or been disabled.
.No traffic or other objects are
being detected.
.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 stopped vehicle ahead has
driven away and ACC has not
resumed, the vehicle ahead symbol
will flash as a reminder to check
traffic before proceeding. In
