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.
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 4-6 and
DIC Warnings and Messages on page 3-60 for
more information.
StabiliTrak ® Indicator Light
This light comes on briefly
while starting the engine.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light will then go off.
