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.
Ride Control Systems
Traction Control
System (TCS)
The vehicle has a Traction Control
System (TCS) that limits wheel spin.
This is especially useful in slippery
road conditions. The system
operates only if it senses that the
rear wheels are spinning too much
or are beginning to lose traction.
When this happens, the system
works the rear brakes and reduces
engine power (by closing the throttle
and managing engine spark) to limit
wheel spin.
The TRACTION SYSTEM ACTIVE
message displays on the Driver
Information Center (DIC) when TCS
is limiting wheel spin. SeeRide
Control System Messages on
page 5‑44. The system may be
heard or felt while it is working,
but this is normal. If cruise control is being used when
TCS begins to limit wheel spin, the
cruise control will automatically
disengage. Cruise control may be
reengaged when road conditions
allow. See
Cruise Control on
page 9‑44.
The SERVICE TRACTION SYSTEM
message and the TCS warning light
will come on if there is a problem
with TCS. See Ride Control System
Messages on page 5‑44.
When this light and the SERVICE
TRACTION SYSTEM message
are on, the system will not limit
wheel spin. Adjust your driving
accordingly.

Driving and Operating 9-37
TCS automatically comes on
whenever the vehicle is started.
To limit wheel spin, especially in
slippery road conditions, the system
should always be left on. TCS can
be turned off if needed.
To turn the system off, press the
button located on the console.
The system can be turned on or off
at any time by pressing the ACTIVE
HANDLING button. The DIC will
display the appropriate message
when the button is pushed.
Notice:When traction control is
turned off, or Competitive Driving
Mode is active, it is possible to
lose traction. If you attempt to shift with the drive wheels
spinning with a loss of traction, it
is possible to cause damage to
the transmission. Do not attempt
to shift when the drive wheels do
not have traction. Damage caused
by misuse of the vehicle is not
covered. See the warranty book
for additional information.
Adding non‐dealer/non-retailer
accessories can affect the vehicle's
performance. See
Accessories and
Modifications on page 10‑4 for more
information.
Active Handling System
The Active Handling System is
a computer controlled system
that helps the driver maintain
directional control of the vehicle
in difficult driving conditions.
This is accomplished by selectively
applying any one of the vehicle's
brakes. The ACTIVE HANDLING message
will come on when the system is
operating. See
Ride Control System
Messages on page 5‑44 for more
information. The system may be
heard or felt while it is working.
This is normal.
The SERVICE ACTIVE HANDLING
SYSTEM message is displayed, the
instrument cluster light comes on,
and a sound is heard if there is a
problem with the system.
See Ride Control System Messages
on page 5‑44 for more information.
When this light and the SERVICE
ACTIVE HANDLING SYSTEM
message are on, the system is not
operational. Adjust your driving
accordingly.

.The Active Handling System
will feel different in aiding and
maintaining directional control.
Competitive Driving Mode
Competitive Driving Mode,
Performance Traction Management,
and Launch Control are systems
designed to allow increased
performance while accelerating
and/or cornering. This is
accomplished by regulating and
optimizing the engine, brakes,
and suspension performance.
These modes are for use at a
closed course race track and are
not intended for use on public
roads. They will not compensate
for a driver
’s inexperience or lack
of familiarity with the race track.
Drivers who prefer to allow the
system to have more control of
the engine, brake, and suspension
are advised to turn the normal
traction control and active handling
systems on. See Racing or Other
Competitive Driving on page 9‑7
for more information.
