If the vehicle has Electronic Stability Control (ESC) and
the 2.0L turbocharged engine, it also has a hydraulic
brake boost feature which supplements the power brake
system to maintain consistent brake performance
under conditions of low brake booster vacuum.
Low brake booster vacuum conditions can include initial
start up after the vehicle has been parked for several
hours, very frequent brake stops, or high altitude driving.
When hydraulic brake boost is active, minor brake
pulsation or movement might be felt but this is normal.
If brake pedal feel changes or the brake pedal feels
hard to push, the system might not be receiving
the intended brake boost and the SVC BRAKE SYSTEM
DIC message may be displayed.
Under certain weather or operating conditions,
occasional brake squeak, squeal, or other noise might
be heard with the vehicle’s performance braking system.
The brake system on SS models is designed for
superior fade resistance and consistent operation using
high performance brake pads. Brake noise and brake
dust are normal and do not affect system performance.
Adding non-dealer/non-retailer accessories can affect
vehicle performance. See Accessories and Modifications
on page 5-3.
Antilock Brake System (ABS)
The vehicle might have the Antilock Brake System (ABS),
an advanced electronic braking system that helps prevent
a braking skid.
If the vehicle has ABS,
this warning light on the
instrument panel comes on
briefly when the vehicle
is started.
When the engine is started, or when the vehicle begins
to drive away, ABS checks itself. A momentary motor
or clicking noise might be heard while this test is going
on, and it might even be noticed that the brake pedal
moves or pulses a little. This is normal.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that the wheels are slowing down.
If one of the wheels is about to stop rolling, the computer
will separately work the brakes at each wheel.
