Braking in Emergencies
ABS allows the driver to steer and brake at the same
time. In many emergencies, steering can help more
than even the very best braking.
Brake Assist
This vehicle has a brake assist feature that responds to
emergency braking by generating additional pressure
and engaging the ABS. When this happens, the brake
pedal will feel easier to push. Just hold the brake pedal
down firmly and let the system work for you. You might
feel the brakes vibrate or notice some noise, but this is
normal. The brakes will return to normal operation after
the brake pedal is released.
Brake assist cannot compensate for unsafe driving
practices and braking effectiveness, itself, depends on
the condition of the road, tires, and brakes and
vehicle mass.
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. See DIC Warnings and Messages
on page 4‑52. 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 4‑7.

The SERVICE
TRACTION SYSTEM
message and the
TCS warning light will
come on if there is a
problem with TCS.
See DIC Warnings and
Messages on page 4‑52.
When this light and the SERVICE TRACTION SYSTEM
message are on, the system will not limit wheel spin.
Adjust your driving accordingly.
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 6‑3for 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 DIC Warnings and
Messages
on page 4‑52for 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 DIC Warnings and Messages
on page 4‑52for
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 comes on automatically
whenever the vehicle is started. To help maintain
directional control of the vehicle, the system should
always be left on. The system can be turned off
needed. If the Active Handling System is turned off,
the Traction Control System will also be turned off.
Adjust your driving accordingly.
To turn the system off,
press the Active Handling
button on the console until
TRACTION SYSTEM
AND ACTIVE HANDLING
SYSTEM
—OFF is
displayed.
The system can be turned back on at any time by
pressing the button. The DIC will display the appropriate
message when the button is pushed.

If the Tire Pressure Monitor (TPM) system detects a flat
tire and the Driver Information Center (DIC) displays
TIRE FLAT, or if the TPM system is malfunctioning and
the DIC displays SERVICE TIRE MONITOR, the Active
Handling System will be affected as follows:
.The Active Handling System cannot be turned off
by the driver.
.If the Active Handling System is off, it will be
turned on automatically.
.Competitive Driving Mode or Performance Traction
Management is unavailable.
.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 5‑19for more information.
Notice: Do not attempt to shift when the drive
wheels are spinning and do not have traction. This
may cause damage to the transmission. Damage
caused by misuse of the vehicle is not covered by
the vehicle warranty. See the warranty book for
additional information.
Competitive Driving Mode (Except ZR1)
Competitive Driving Mode allows full engine power
while the Active Handling System helps maintain
directional control of the vehicle by selective brake
application. In this mode, TCS is off and Launch Control
is available. Adjust your driving style to account for the
available engine power. See Launch Control later in
this section.

Performance Traction
Management (ZR1)
Performance Traction Management integrates the
Traction Control, Active Handling and Selective Ride
Control systems to provide improved and consistent
performance when cornering. The amount of available
engine power is based on the mode selected, track
conditions, driver skill, and the radius of each corner.
This light is on when
the vehicle is in the
Performance Traction
Management Mode.
This optional handling mode can be selected by

system, after entering a curve and at the point where
the driver would normally start to increase acceleration,
the accelerator pedal can be fully pressed. The
Performance Traction Management system will modify
the level of engine power for a smooth and consistent
corner exit.
To select a mode while in
Performance Traction
Management, turn the
knob located on the
console.
The Performance Traction Management system
contains five modes. These modes are selected by
turning the Selective Ride Control/Performance Traction
Management knob on the center console. The driver
scrolls up or down through modes 1-5 by rotating the
knob to the right or left. The following is a DIC display description and the
