If enabled, this light comes on briefly when the vehicle is started. 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.

This light also comes on when the vehicle is operating at a fuel efficient point.

This light can be disabled by using the Driver Information Center (DIC) buttons. With the engine off and the key turned to ACC/ACCESSORY, set the DIC to the outside air temperature and odometer mode. Press and hold the reset button for several seconds. The light comes on steady and then flashes several times and turns off to indicate it is disabled. Repeat the procedure to enable the light. See DIC Warnings and Messages for more information.
