For vehicles with footwell lamps, they are located under the instrument panel and at the rear of the front seats. These lamps provide soft light to the front and rear floor areas. They dim with the instrument panel cluster lights.

Footwell lighting brightness can be adjusted with the instrument panel brightness control located below the exterior lamps control. See Instrument Panel Brightness . The footwell lights will turn off before the instrument panel lights are at their lowest level of brightness.
