Cargo Lamp
The cargo lamps come on by turning the instrument panel brightness control knob to the farthest clockwise position. This knob is located on the instrument panel and also turns on the dome lamps.
The cargo lamps can be used if more light is needed in the cargo area of the vehicle or in the top-box storage units.
