When it is dark enough outside, the automatic system turns on the headlamps at the normal brightness along with other lamps such as the taillamps, sidemarker, parking lamps, instrument panel lights, and interior switch backlighting.

Do not cover the light sensor, located on top of the instrument panel. If the sensor is covered the headlamps may remain on when they are not needed.

If the vehicle is driven through a parking garage, overcast weather or a tunnel, the automatic headlamp system may turn on.

There is a delay in the transition between the daytime and nighttime operation of the automatic lamp control system so that driving under bridges or bright overhead street lights does not affect the system. The automatic lamp control system will only be affected when the light sensor sees a change in lighting lasting longer than this delay.

If the vehicle is started in a dark garage, the automatic lamp system turns on immediately. Once the vehicle exits the garage, it will take about 20 seconds for the automatic lamp system to change to DRL if it is light outside. During that delay, the instrument panel cluster may not be as bright as usual. Make sure the instrument panel brightness control is in the full bright position. See Instrument Panel Brightness .

To idle the vehicle with the system off, turn the ignition on and turn the exterior light switch to the off/on position. For vehicles first sold in Canada, the transmission must stay in P (Park) for this function or the parking brake must be set for vehicles with manual transmissions.

Turn on the regular headlamps when they are needed.
