Braking In Emergencies - GMC 2001 Sierra 1500 Pickup Owner's Manual

-
Remember: Anti lock doesn't 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 won't 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
-
anti lock brakes.
-
Using Anti Lock
Don't pump the brakes. Just hold the brake pedal down
-
firmly and let anti lock work for you. You may feel the
brakes vibrate, or you may notice some noise, but this
is normal.

Braking in Emergencies

-
With anti lock, you can steer and brake at the same
time. In many emergencies, steering can help you
more than even the very best braking.
Traction Assist System (Option)
Your vehicle may have a Traction Assist System (TAS)
that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if it
senses that one or both of the rear wheels are spinning
or beginning to lose traction. When this happens, the
system reduces engine power to limit wheel spin.
You may hear or feel the system working or notice a
lack of accelerator response, but this is normal.
This light will come
on when the TAS is
limiting wheel spin.
See "Low Traction Light"
in the Index.
