Braking In Emergencies; Traction Control System (Tcs) - Pontiac 2008 G5 Owner's Manual

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 — might 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 Antilock Brake System (ABS)
on page 4-5.
In many emergencies, steering can help you more than
even the very best braking.

Traction Control System (TCS)

Your vehicle may have a Traction Control System (TCS)
that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if it
senses that the wheels are spinning too much or are
beginning to lose traction. When this happens, the
system works the front brakes and reduces engine power
by closing the throttle and managing engine spark to limit
wheel spin.
If your vehicle has TCS, there is a ESC/TCS button
located on the instrument panel.
You may feel or hear the system working, but this is
normal.
See Electronic Stability Control (ESC)/Traction Control
System (TCS) Indicator/Warning Light on page 3-35
for more information.
This light flashes while the
traction control system is
limiting wheel spin.
