Avoid needless heavy braking. Some people drivein spurts — heavy acceleration followed by heavybraking — rather than keeping pace with traffic.This is a mistake. The brakes may not have timeto cool between hard stops. The brakes will wearout much faster if you do a lot of heavy braking.If you keep pace with the traffic and allow realisticfollowing distances, you will eliminate a lot ofunnecessary braking. That means better brakingand longer brake life.If your vehicle’s engine ever stops while you are driving,brake normally but do not pump the brakes. If you do,the pedal may get harder to push down. If the enginestops, you will still have some power brake assist.But you will use it when you brake. Once the powerassist is used up, it may take longer to stop andthe brake pedal will be harder to push.Adding non-GM accessories can affect your vehicle’sperformance. See Accessories and Modificationson page 5-3.Anti-Lock Brake System (ABS)Your vehicle has the Anti-Lock Brake System (ABS),an advanced electronic braking system that willhelp prevent a braking skid.When you start your engine and begin to drive away,ABS will check itself. You may hear a momentary motoror clicking noise while this test is going on, and youmay even notice that your brake pedal moves alittle. This is normal.If there is a problem withABS, this warning light willstay on. See Anti-LockBrake System WarningLight on page 3-39.4-7
