It controls the following systems:

    • Headlamps

The exterior lamps control has four positions:

(Off): Turns off the automatic headlamps and daytime running lamps (DRL). Turning the headlamp control to the off position again will turn the automatic headlamps or DRL back on. For vehicles first sold in Canada, the off position will only work for vehicles that are shifted into the P (Park) position.

AUTO (Automatic): Automatically turns on the headlamps at normal brightness, together with the following:

    • Parking Lamps
    • Instrument Panel Lights
    • Taillamps
    • License Plate Lamps

When the headlamps are turned on while the vehicle is on, the headlamps will turn off automatically 10 minutes after the ignition is turned off. When the headlamps are turned on while the vehicle is off, the headlamps will stay on for 10 minutes before automatically turning off to prevent the battery from being drained. Turn the headlamp control to off and then back to the headlamp on position to make the headlamps stay on for an additional 10 minutes.
