StabiliTrak
®
Indicator
Light
For vehicles with the StabiliTrak
system, this light comes on briefly
while starting the engine.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light then goes off.
If the light comes on and stays on
while driving, there could be a
problem with the StabiliTrak system
and the vehicle might need service.
When this warning light is on, the
StabiliTrak system is off and does
not limit wheel spin.
The light flashes if the system is
active and is working to assist the
driver with directional control of the
vehicle in difficult driving conditions.
