Pontiac G5 Automobile User Manual


 
Using ABS
Do not pump the brakes. Just hold the brake pedal down
firmly and let antilock work. A slight brake pedal pulsation
might be felt or some noise noticed, but this is normal.
Braking in Emergencies
At some time, nearly every driver gets into a situation
that requires hard braking.
If the vehicle has ABS, it allows the driver to steer and
brake at the same time. However, if the vehicle does not
have ABS, the first reaction — to hit the brake pedal hard
and hold it down — might be the wrong thing to do. The
wheels can stop rolling. Once they do, the vehicle cannot
respond to the driver’s 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 the driver was trying to avoid, or into traffic.
If the vehicle does not have ABS, use a “squeeze”
braking technique. This gives maximum braking while
maintaining steering control. 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 helps retain steering control. With ABS, it is
different. See Antilock Brake System (ABS) on page 4-5.
In many emergencies, steering can help more than
even the very best braking.
Electronic Stability Control (ESC)
The vehicle may have an Electronic Stability Control
(ESC) system which combines antilock brake, and
traction and stability control systems that help the driver
maintain directional control of the vehicle in most driving
conditions.
When the vehicle is started and begins to move, the
system performs several diagnostic checks to ensure
there are no problems. The system may be heard or felt
while it is working. This is normal and does not mean
there is a problem with the vehicle. The system should
initialize before the vehicle reaches 20 mph (32 km/h).
