If your vehicle has this feature, this light will come on briefly as a bulb check when your ignition is turned to ON.

This light will come on and a warning chime will sound if you have certain non-emissions related vehicle problems. These problems may not be so obvious and may not affect vehicle performance or durability. Consult a qualified dealership for necessary repairs to maintain top vehicle performance.

On vehicles with the supercharged engine and a DIC, the SERVICE VEHICLE SOON light is replaced by the SERVICE VEHICLE SOON message. See DIC Warnings and Messages for more information.
