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 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. Adding non-dealer/non-retailer accessories can affect vehicle performance. See Accessories and Modifications on page 6‑4. 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. 5-4

eliminates a lot of unnecessary braking. That means
better braking and longer brake life.

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.
