Pontiac 2006 Grand Prix - Manual (Page 269)

If you do not have anti-lock brakes, 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
anti-lock brakes, it is different. See Anti-Lock Brake
System (ABS) on page 4-7.
In many emergencies, steering can help you more than
even the very best braking.
Traction Control System (TCS)
If the vehicle has the 3800 Supercharged V6 engine
or the 5.3L V8 engine, it 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 front wheels are
spinning or beginning to lose traction. When this
happens, the system works the front brakes and
reduces engine power to limit wheel spin.
This symbol, along with the
TRACTION CONTROL
ACTIVE message, comes
on the DIC screen when
the system is active.
You may feel or hear the system working, but this
is normal.
When the traction control system is not working, one of
these symbols will come on the instrument panel cluster.
