Parking Brake
With the brake pedal applied, pull
up firmly on the parking brake
handle without pressing the release
button. SeeShifting Into Park 0177.
If the ignition is on, the brake
system warning light will come on.
See Brake System Warning Light
0 102.
To release the parking brake: 1. Hold the brake pedal down.
2. Pull the parking brake handle up until you can press the
release button. 3. Hold the release button in as
you move the brake handle all
the way down.
Caution
Driving with the parking brake on
can overheat the brake system
and cause premature wear or
damage to brake system parts.
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.
Driving with the parking brake
applied will cause a warning chime
to sound and a Driver Information
Center (DIC) message to display.
Release the parking brake or stop
the vehicle.
Brake Assist
Brake Assist detects rapid brake
pedal applications due to
emergency braking situations and
provides additional braking to activate the Antilock Brake System
(ABS) if the brake pedal is not
pushed hard enough to activate
ABS normally. Minor noise, brake
pedal pulsation, and/or pedal
movement during this time may
occur. Continue to apply the brake
pedal as the driving situation
dictates. Brake Assist disengages
when the brake pedal is released.
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA feature.
HSA does not replace the need to
pay attention and drive safely.
You may not hear or feel alerts or
warnings provided by this system.
Failure to use proper care when
driving may result in injury, death,
or vehicle damage. See
Defensive Driving
0160.

Driving and Operating 185
When the vehicle is stopped on a
grade, Hill Start Assist (HSA)
temporarily prevents the vehicle
from rolling in an unintended
direction during the transition from
brake pedal release to accelerator
pedal apply. The brakes release
when the accelerator pedal is
applied or automatically release
after a few seconds. The brakes
may also release under other
conditions. Do not rely on HSA to
hold the vehicle.
HSA is available when the vehicle is
facing uphill in a forward gear,
or when facing downhill in
R (Reverse). The vehicle must
come to a complete stop on a grade
for HSA to activate.Ride Control Systems
Traction Control/
Electronic Stability
Control
System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak/
Electronic Stability Control (ESC),
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/ESC activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak/ESC selectively applies
braking pressure to any one of thevehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
If cruise control is being used and
TCS or StabiliTrak/ESC 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 0165
and “Turning the Systems Off and
On” later in this section.

186 Driving and Operating
The indicator light for both systems
is in the instrument cluster. This
light will:
.Flash when TCS is limiting
wheel spin.
. Flash when StabiliTrak/ESC 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.

Cruise Control
If the vehicle is equipped 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 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 the vehicle's Traction Control
System (TCS) or StabiliTrak/
Electronic Stability Control (ESC)
system begins to limit wheel spin
while using cruise control, the cruise
control will automatically disengage.
See
Traction Control/Electronic
Stability Control 0185. If a collision
alert occurs when cruise control is
activated, cruise control is
disengaged. See Forward Collision
Alert (FCA) System 0194. When
road conditions allow you to safely
use it again, the cruise control can
be turned back on.
If the brakes are applied, cruise
control disengages.
