Chevrolet Silverado Classic 2007 Owner's Manual page 364

If your vehicle is in cruise control when the TAS
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
on page 215.
The traction off light will come on under the
following conditions:
•
The Traction Assist System is turned off, either
by pressing the TAS on/off button, located on
the instrument panel, or by turning off the
automatic engagement feature of the TAS.
•
The transmission is in FIRST (1); TAS will not
operate in this gear. This is normal.
•
The vehicle is driven on an extremely rough
road. When the vehicle leaves the rough
surface, slows down or stops, the light will go
off and TAS will turn on again. This is normal.

When the traction off
light is on, the TAS is
off and will not limit
wheel spin. Adjust your
driving accordingly.
•
A Traction Assist System, Anti-Lock Brake
System or engine-related problem has been
detected and the vehicle needs service.
•
If the vehicle has been driven with the TAS
system on for long periods of time, or if the
vehicle has gone through many several high
speed braking maneuvers the system may be
automatically disabled. The system will
automatically re-enable after approximately
two minutes of not using the brakes.
See Traction Off Light on page 255.
The Traction Assist System, as delivered from the
factory, will automatically come on whenever
you start your vehicle. To limit wheel spin,
especially in slippery road conditions, you should
always leave the system on. But you can turn
the TAS off if you ever need to. You should turn
the TAS off if your vehicle ever gets stuck in sand,
mud or snow and rocking the vehicle is required.
See Rocking Your Vehicle to Get It Out on
page 407 and If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow on page 406.
