Traction Control System (Tcs) Warning Light - Chevrolet 2009 Impala Owner's Manual

If the regular brake system warning light is not on, the
vehicle still has brakes, but not antilock brakes. If the
regular brake system warning light is also on, the vehicle
does not have antilock brakes and there is a problem with
the regular brakes. See Brake System Warning Light on
page 3-30.
For vehicles with a Driver Information Center (DIC),
see DIC Warnings and Messages on page 3-49 for
all brake related DIC messages.
Traction Control System (TCS)
Warning Light
3-32
For vehicles with a Traction
Control System (TCS) and
®
StabiliTrak warning light,
this light comes on briefly
when the engine is started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally
the indicator light then goes off.
When the system is active, the light flashes while the
system is limiting wheel spin or assisting with controlling
the vehicle.
If it stays on or comes on while driving a SERVICE
TRACTION CONTROL message appears in the Driver
Information Center (DIC). This indicates that there could
be a problem with the traction control system and the
vehicle may need service. When this warning light is
on and the SERVICE TRACTION CONTROL message
appears on the DIC, the system does not limit wheel spin.
If the traction control system is manually turned off, this
light comes on and the TRACTION CONTROL OFF
message appears on the DIC.
See Traction Control System (TCS) on page 4-8
and DIC Warnings and Messages on page 3-49 for
more information.
