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. SeeRide 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 on
the DIC, the Active Handling System 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
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 if 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
center console until TRACTION
SYSTEM AND ACTIVE HANDLING
SYSTEM —OFF is displayed on
the DIC.
The StabiliTrak Off light will
come on.
The system can be turned back on
at any time by pressing the Active
Handling 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 9‑6
for 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.

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).
Cruise control will not work if the
parking brake is set, or if the master
cylinder brake fluid level is low.
{WARNING
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the 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 is in cruise control,
and has the Traction Control
System (TCS), and it begins to limit
wheel spin, the cruise control
automatically disengages. See
Traction Control System (TCS) on
page 9‑36. When road conditions
allow the cruise control to be safely
used again, it can be turned
back on.

Driving and Operating 9-47
Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might want to step on the
accelerator pedal to maintain
the vehicle speed. When going
downhill, you might have to brake or
shift to a lower gear to keep the
vehicle's speed down. When the
brakes are applied the cruise control
is disengaged.
Cruise Control in Sport and
Manual Paddle Shift Gear
Selection
When the vehicle is in S (Sport) and
the manual paddle shift controls are
not being used, cruise control
operates in the same manner as
D (Drive).When the vehicle is in S (Sport) and
the manual paddle shift controls are
being used, cruise control operates
as follows:
.If cruise control is active and a
gear is selected with the manual
paddle shift controls, the vehicle
speed is maintained in the driver
selected gear and will not
automatically up-shift or
down-shift the transmission
while the driver
’s gear selection
is active.
.If driving in hilly terrain, cruise
control may not be able to
maintain vehicle speed if an
up-shift or down-shift is not
selected by the driver. While
driving on hilly terrain and cruise
control is active with a manual
paddle shift gear selection, the
driver must select the proper
gear for the terrain or select
D (Drive) on the gear range
selector for full automatic
transmission operation. Ending Cruise Control
.To disengage cruise control,
step lightly on the brake pedal.
If the vehicle has a manual
transmission, lightly tap the
clutch to end the cruise control
session.
.To turn off the cruise control
system, move the cruise control
switch to
9.
When cruise control is disengaged,
the CRUISE DISENGAGED
message displays on the Driver
Information Center (DIC). See
Cruise Control Messages on
page 5‑38.
Erasing Speed Memory
The cruise control set speed is
erased from memory by moving
the switch to
9or if the ignition is
turned off.
