Audio System(s)
Determine which radio the vehicle has and read the
following pages to become familiar with its features.
{WARNING:
Taking your eyes off the road for extended periods
could cause a crash resulting in injury or death to
you or others. Do not give extended attention to
entertainment tasks while driving.
This system provides access to many audio and non
audio listings.
To minimize taking your eyes off the road while driving,
do the following while the vehicle is parked:
.Become familiar with the operation and controls of
the audio system.
.Set up the tone, speaker adjustments, and preset
radio stations.
For more information, see Defensive Driving
on
page 5‑2. Notice:
Contact your dealer/retailer before adding
any equipment.
Adding audio or communication equipment could
interfere with the operation of the vehicle's engine,
radio, or other systems, and could damage them.
Follow federal rules covering mobile radio and
telephone equipment.
Notice: The chime signals related to safety belts,
parking brake, and other functions of your vehicle
operate through the radio/entertainment system.
If that equipment is replaced or additional
equipment is added to your vehicle, the chimes
may not work. Make sure that replacement or
additional equipment is compatible with your
vehicle before installing it. See Accessories and
Modifications on page 6‑3.

Avoid needless heavy braking. Some people drive in
spurts, heavy acceleration followed by heavy braking,
rather than keeping pace with traffic. This is a mistake.
The brakes might not have time to cool between hard
stops. The brakes will wear out much faster with a
lot of heavy braking. Keeping pace with the traffic and
allowing realistic following distances eliminates a lot of
unnecessary braking. That means better braking and
longer brake life.
If the engine ever stops while the vehicle is being
driven, brake normally but do not pump the brakes.
If the brakes are pumped, the pedal could get harder
to push down. If the engine stops, there will still be
some power brake assist but it will be used when the
brake is applied. Once the power assist is used up, it
can take longer to stop and the brake pedal will be
harder to push.
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 pedalfeel 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.
Adding non‐dealer/non‐retailer accessories can affect
vehicle performance. See
Accessories and
Modifications on page 6‑3.
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.
