CHEVROLET 2010 Impala - Manual (Page 178)

Antilock Brake System (ABS)
Warning Light
The Antilock Brake
System (ABS) 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.
If the ABS light stays on, turn the ignition off. If the light
comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on, or
comes on again while driving, the vehicle needs service.
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 4-27.
For vehicles with a Driver Information Center (DIC),
see DIC Warnings and Messages on page 4-44 for all
brake related DIC messages.
Traction Control System (TCS)
Warning Light
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.
