stationary for up to two seconds after
the brake pedal is released. When
Extended Hold is selected, the vehicle
is held stationary for up to
five minutes after the brake pedal is
released. In either case, override the
hold feature by pressing the
accelerator pedal and attempting to
drive away.
If Standard Hold is selected, it will
hold the vehicle for two seconds
unless the driver door is opened or
the driver seat belt is unbuckled after
releasing the brake pedal. If Extended
Hold is selected, it will hold the
vehicle for five minutes unless the
driver door is opened and the driver
seat belt is unbuckled prior to
releasing the brake pedal. When
deactivated after five minutes, or if it
is deactivated when the driver seat
belt is unlatched or the driver door is
opened, the Electric Parking Brake will
engage to prevent vehicle movement.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 spin
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 in
AWD or Sport Mode, 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. TCS and StabiliTrak will
automatically turn on when cruise
control is set.
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 0184 and “Turning
the Systems Off and On ”later in this
section.

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).
If the Traction Control/electronic
stability control system begins to limit
wheel spin while using cruise control,
the cruise control automatically
disengages. See Traction Control/
Electronic Stability Control 0205. If a collision alert occurs when cruise
control is activated, cruise control is
disengaged. See
Forward Collision Alert
(FCA) System 0226. When road
conditions allow cruise control to be
safely used, it can be turned back on.
Cruise control will disengage if either
TCS or StabiliTrak is turned off.
If the brakes are applied, cruise
control disengages.
J: Press to turn the system on and
off. A white indicator appears in the
instrument cluster when cruise is
turned on. RES+ :
If there is a set speed in
memory, press briefly to resume to
that speed or press and hold to
accelerate. If the cruise control is
already active, use to increase vehicle
speed. To increase speed by 1 km/h
(1 mph), press RES+ to the first detent.
To increase speed to the next 5 km/h
(5 mph) mark on the speedometer,
press RES+ to the second detent.
SET− :Press briefly to set the speed
and activate cruise control. If the
cruise control is already active, use to
decrease vehicle speed. To decrease
speed by 1 km/h (1 mph), press SET−
to the first detent. To decrease speed
to the next 5 km/h (5 mph) mark on
the speedometer, press SET− to the
second detent.
*: Press to disengage cruise control
without erasing the set speed from
memory.

210 DRIVING AND OPERATING
The cruise control system may
automatically brake to slow the
vehicle down.
The speedometer reading can be
displayed in either English or metric
units. SeeInstrument Cluster (Uplevel
Cluster) 0125 orInstrument Cluster
(Base Level Cluster) 0123. 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 previous set cruise speed.
While pressing the accelerator pedal
or shortly following the release to
override cruise, briefly applying SET−
will result in cruise set to the current
vehicle speed.
Using Cruise Control on Hills
How well the 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 your 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 your speed down. If the brake
pedal is applied, cruise control
disengages.
Ending Cruise Control
There are four ways to end cruise
control:
.
Step lightly on the brake pedal.
. Press
*.
. Shift the transmission to
N (Neutral).
. Press
J.
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
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. See
Radio Frequency Statement
0353.
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
electronic stability control system
activates, the ACC may automatically
disengage. See Traction Control/
Electronic Stability Control 0205. 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 electronic stability control
system is disabled.

feel or sound different than if the
brakes were applied manually. This is
normal.
Stationary or Very Slow-Moving
Objects
{Warning
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 electronic stability control
system has activated or been
disabled.
. There is a fault in the system.
. The radar falsely reports blockage
when driving in a desert or remote
area with no other vehicles or
roadside objects. A DIC message
may display to indicate that ACC
is temporarily unavailable.
The ACC indicator will turn white
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 indicator
will flash as a reminder to check traffic ahead before proceeding. 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 “Adaptive Cruise Go
Notifier” in“Collision/Detection
Systems” underVehicle Personalization
0 148.
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 seat belt
is unbuckled, the ACC automatically
applies the Electric Parking Brake
(EPB) to hold the vehicle. The EPB
status light will turn on. See Electric
Parking Brake 0203. To release the
EPB, press the accelerator pedal.
A DIC warning message may display
indicating to shift to P (Park) before
exiting the vehicle. See Vehicle
Messages 0147.

Electric Trailer Brake Control Wiring
Provisions
These wiring provisions for an electric
trailer brake controller are included
with the vehicle as part of the trailer
wiring package. The instrument panel
contains blunt cut wires above the
parking brake assembly for the electric
trailer brake controller. The harness
contains the following wires:
.Blue: To Trailer
. Red/Black or Red/Blue:
Battery Feed
. White/Blue: Brake Apply Signal
. Black: Ground
The electric trailer brake controller
should be installed by your dealer or a
qualified service center.Trailer Sway Control (TSC)
Vehicles with StabiliTrak have a
Trailer Sway Control (TSC) feature.
Trailer sway is unintended side-to-side
motion of a trailer while being towed.
If the vehicle is towing a trailer and
the TSC detects that sway is
increasing, the vehicle brakes are
selectively applied at each wheel, to
help reduce excessive trailer sway.
If the vehicle is equipped with the
Integrated Trailer Brake Control
(ITBC) system, and the trailer has the
electric actuated brake system,
StabiliTrak may also apply the trailer
brakes.
If TSC is enabled, the Traction Control
System (TCS)/StabiliTrak warning
light will flash on the instrument
cluster. Vehicle speed must be
reduced. If trailer sway continues,
StabiliTrak can reduce engine torque
to help slow the vehicle. See Traction
Control/Electronic Stability Control
0 205.{Warning
Even if the vehicle is equipped with
TSC, trailer sway could result in
loss of control and the vehicle could
crash. If excessive trailer sway is
detected, slow down to a safe speed.
Check the trailer and vehicle to help
correct possible causes. These could
include an improperly or overloaded
trailer, unrestrained cargo, improper
trailer hitch configuration, excessive
vehicle-trailer speed, or improperly
inflated or incorrect vehicle or
trailer tires. See Towing Equipment
0 245 for trailer ratings and hitch
setup recommendations.
Adding non-dealer accessories can
affect the vehicle performance. See
