GMC 2007 Automobile User Manual


 
Remember: ABS does not change the time you
need to get your foot up to the brake pedal
or always decrease stopping distance. If you get
too close to the vehicle in front of you, you will not
have time to apply your brakes if that vehicle
suddenly slows or stops. Always leave enough
room up ahead to stop, even though you
have ABS.
Using ABS
Do not pump the brakes. Just hold the brake pedal
down firmly and let anti-lock work for you. You may
feel a slight brake pedal pulsation or notice some
noise, but this is normal.
Braking in Emergencies
At some time, nearly every driver gets into a
situation that requires hard braking.
If you have ABS, you can steer and brake at the
same time. However, if you do not have ABS, your
first reaction to hit the brake pedal hard and
hold it down may be the wrong thing to do.
Your wheels can stop rolling. Once they do, the
vehicle cannot respond to your steering.
Momentum will carry it in whatever direction it was
headed when the wheels stopped rolling. That
could be off the road, into the very thing you were
trying to avoid, or into traffic.
If you do not have ABS, use a “squeeze” braking
technique. This will give you maximum braking
while maintaining steering control. You can do this
by pushing on the brake pedal with steadily
increasing pressure.
In an emergency, you will probably want to squeeze
the brakes hard without locking the wheels. If you
hear or feel the wheels sliding, ease off the brake
pedal. This will help you retain steering control. If
you do have ABS, it is different. See Anti-Lock
Brake System (ABS) on page 225.
In many emergencies, steering can help you more
than even the very best braking.
Steering
Power Steering
If you lose power steering assist because the
engine stops or the system is not functioning, you
can steer but it will take much more effort.
