Traction Control System (Tcs); Braking In Emergencies - GMC Chevrolet SSR 2003 Owner's Manual

Remember: Anti-lock 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 anti-lock brakes.
Using Anti-Lock
Do not 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 Control System (TCS)

Your vehicle has 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 one or both of the rear wheels are spinning or
beginning to lose traction. When this happens,
the system reduces engine power and may also
upshift the transmission to limit wheel spin.
You may feel or hear the system working, but this
is normal.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
re-engage the cruise control. See "Cruise Control"
in Turn Signal/Multifunction Lever on page 3-5.
The Traction Control System operates in all transmission
shift lever positions except for first gear. This is
normal. The system is deactivated when the
transmission is shifted into first gear. In this situation,
the "TRAC OFF" light on the instrument panel cluster will
come on. This is normal. The system can upshift the
transmission only as high as the shift lever position
you've chosen, so you should use the lower gears only
when necessary. See Automatic Transmission
Operation on page 2-17.
