Traction Control System (TCS)
Warning Light
The Traction Control
System (TCS) light comes
on briefly when the engine
is started.
If it does not, have the vehicle serviced by your dealer.
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.
