PERFORMANCE & MAINTENANCE
Antilock Brake System
The Antilock Brake System (ABS) is an
advanced electronic system that will
help prevent a braking skid. When oper-
ating the brakes, do not pump the brake
pedal. Just hold the brake pedal down
firmly. You may feel a slight brake pedal
pulsation or notice some noise, but this
is normal.
See Section 4 of your Owner Manual.
Traction Control System
The Traction Control
System activates
every time you start
your vehicle. When
one or more of the
drive wheels begin to
spin from traction
loss, the Traction
Control System will
reduce engine power, indicated by a
flashing light on the instrument panel.
The front brakes may be applied and the
transaxle may upshift to help regain
traction. If your vehicle becomes stuck
and rocking the vehicle is required, the
system should be turned off.
To deactivate the Traction Control
System, press the traction control button
on the left side of the instrument panel.
When the system is turned off, the trac-
tion control light will illuminate.
See Section 4 of your Owner Manual.

– Stability Control
System (if equipped)
StabiliTrak is an advanced computer-

vehicle in difficult driving conditions. It
turns on automatically every time you
start your vehicle.
When the system senses a discrepancy
between your intended path and the
direction the vehicle is actually traveling,
it selectively applies brake pressure at
any one of the wheels to help steer the
vehicle in the direction in which you are
steering.
See Section 4 of your Owner Manual.

when a significant reduction in pressure
occurs in one or more of your vehicle's
tires by illuminating the
