Chevrolet Cobalt Owners Manual: Enhanced Traction System (ETS) Indicator/Warning Light

For vehicles with the Enhanced Traction
System (ETS), this light serves as an indicator
and warning light.

This light comes on briefly while 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 indicator/warning light is on and not flashing, the ETS system could have been disabled. Check all related Driver Information Center (DIC) messages to determine whether the system has been turned off or if the system is not working properly and the vehicle requires service. If the ETS has been disabled, wheel spin is not limited.

If the indicator/warning light is on and flashing, the ETS is actively working. The LOW TRACTION DIC message also appears when the system is actively limiting wheel spin.

See Enhanced Traction System (ETS) and DIC Warnings and Messages for more information.
