GMC sierra 2002 Manuale Utente

If you have the Traction
Assist System, this light
should come on briefly
when you turn the ignition
to RUN.

If the light doesn’t come on then, the system may
require service; have it fixed so it will be there to warn
you if the system is turned off.

If the light stays on, or comes on when you’re driving,
there may be a problem with your Traction Assist
System and your vehicle may need service. When this
light is on, the system will not limit wheel spin. Adjust
your driving accordingly.

The TRACTION OFF light may come on for the
following reasons:
D If you turn the system off by pressing the TAS on/off

button the light will come on and stay on. To turn the
system back on, press the button again; the light
should go off.

D If you move the shift lever to FIRST (1), the light

will come on and stay on to indicate that the traction
system is off. This is normal operation. To turn the
system back on, move the shift lever back to a
position other than FIRST (1); the light should go
off. See “Traction Assist System” in the Index.

D The light will come on and stay on if the TAS

automatic engagement feature has been turned off.
To turn the system on, press the TAS off/on button;
the light should go off. To turn the automatic
engagement feature back on, see “Traction Assist
System” in the Index.

D If the Traction Assist System is affected by an

anti

-

lock brake system, TAS or engine

-

related

problem, the system will turn off and the light will
come on. Have your vehicle serviced.

D If the vehicle is driven over an extremely rough road,

the system will turn off and the light will come on.
The light will go off a few seconds after the rough
road conditions go away or when the vehicle comes
to a complete stop. This is normal operation.
