If the amber parking brake warning
light is on, lift up on the EPB switch
and hold it up. Continue to hold the
switch until the red parking brake
status light remains on. If the amber
parking brake warning light is on, see
your dealer.
If the EPB is applied while the vehicle
is moving, the vehicle will decelerate
as long as the switch is held up. If the
switch is held up until the vehicle
comes to a stop, the EPB will remain
applied.
The vehicle may automatically apply
the EPB in some situations when the
vehicle is not moving. This is normal,
and is done to periodically check the
correct operation of the EPB system.
If the EPB fails to apply, the rear
wheels should be blocked to prevent
vehicle movement.
EPB Release
To release the EPB:1. Place the ignition in the ACC/ ACCESSORY or ON/RUN
position.
2. Apply and hold the brake pedal. 3. Press the EPB switch
momentarily.
The EPB is released when the red
parking brake status light is off.
If the amber parking brake warning
light is on, release the EPB by pressing
and holding the EPB switch. Continue
to hold the switch until the red
parking brake status light is off.
If either light stays on after release is
attempted, see your dealer.
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.
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to drive away. Avoid rapid acceleration when
the EPB is applied, to preserve parking
brake lining life.
Brake Assist
This vehicle has a brake assist feature
designed to assist the driver in
stopping or decreasing vehicle speed
in emergency driving conditions. This
feature uses the stability system
hydraulic brake control module to
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.

198 DRIVING AND OPERATING
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. 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 0180 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.
4. 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.

Launch Control (V-Series Only)
A Launch Control feature is available,
within Competitive Driving Mode
(V-Series) or Performance Traction
Management (V-Series), to allow the
driver to achieve high levels of vehicle
acceleration in a straight line. Launch
Control is a form of traction control
that manages tire spin while
launching the vehicle. This feature is
intended for use during closed course
race events where consistent zero to
60 and quarter mile times are
desirable.
Launch Control is only available when
the following criteria are met:
. Competitive Driving Mode is
selected (V-Series) or any of the
Performance Traction
Management modes are selected
(V-Series). The TCS light comes on
the instrument panel and the
appropriate DIC message displays.
. The vehicle is not moving.
. The steering wheel is pointing
straight. .
The brake pedal must be firmly
pressed to the floor, equivalent to
a panic brake event.
. The accelerator pedal is rapidly
applied to wide open throttle. (If
the vehicle rolls due to wide open
throttle, release the throttle, press
the brake pedal more firmly, and
re-apply the accelerator to wide
open throttle.)
The Launch Control feature will
initially limit engine speed as the
driver rapidly applies the accelerator
pedal to wide open throttle. Allow the
engine rpm to stabilize. A smooth,
quick release of the brake pedal, while
maintaining the fully pressed
accelerator pedal, will manage
wheel slip.
After the vehicle is launched, the
system continues in Performance
Traction Management (V-Series).
Competitive Driving Mode, PTM, and
Launch Control are systems designed
for a closed course race track and not
intended for use on public roads. The
systems are not intended to

compensate for lack of driver
experience or familiarity with the race
track.
Limited-Slip Rear Axle
(Except V-Series)
If equipped, the mechanical
limited-slip differential can give more
traction on snow, mud, ice, sand,
or gravel. It works like a standard axle
most of the time, but when traction is
low, this feature allows the drive
wheel with the most traction to move
the vehicle. For vehicles with
limited-slip differential, driven under
severe conditions, the rear axle fluid
should be changed. SeeCompetitive
Driving Mode (FE4 Only) 0201 and
Maintenance Schedule 0307.
Limited-Slip Rear Axle
(V-Series Only)
If equipped, the Electronic
Limited-Slip Differential (ELSD) is
automatically activated. ELSD actively
monitors vehicle sensors and driver
inputs to determine the amount of
change for the conditions. With ELSD,
the vehicle has:
.
Enhanced high-speed control.
. Improved traction through
corners, allowing more
acceleration.
. More precise steering.
. Increased vehicle agility.
. Integration with StabiliTrak.
For vehicles with ELSD, driven under
severe conditions, the rear axle fluid
should be changed. See Competitive
Driving Mode (FE4 Only) 0201 and
Maintenance Schedule 0307.
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 the StabiliTrak
®system begins to
limit wheel spin while using cruise
control, the cruise control
automatically disengages. See Traction
Control/Electronic Stability Control
0 198. If a collision alert occurs when

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 for selecting
the cruise control set speed and
following gap. Read this entire section
before using this system. ACC uses a
camera and radar sensors to detect
other vehicles. The following gap is
the following time (or distance)
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.
If a vehicle is detected in your path,
ACC can speed up the vehicle or apply
limited, moderate braking to maintain
the selected following gap. To
disengage ACC, apply the brake. If the
Traction Control System (TCS) or
StabiliTrak
®electronic stability
control system activates while ACC is engaged, ACC may automatically
disengage. See
Traction Control/
Electronic Stability Control 0198. When
road conditions allow ACC to be safely
used, ACC can be turned back on. ACC
will not engage if the TCS or
StabiliTrak electronic stability control
system 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 0171.
{Warning
ACC will not detect or brake for
children, pedestrians, animals,
or other objects.
Do not use ACC 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.
ACC performance is limited
under these conditions.
. On slippery roads where fast
changes in tire traction can
cause excessive wheel slip.
