The lever on the left side of the steering column operates the exterior lamps.

The exterior lamp switch has the following four positions:

& (Headlamps): Turns on the headlamps, parking lamps, and taillamps.

(Parking Lamps): Turns on the parking lamps and taillamps only.

AUTO (Automatic Headlamp System): Automatically turns on the Daytime Running Lamps (DRL) during daytime, and the headlamps, parking lamps, and taillamps at night. This position must be selected in order for the Wiper Activated Headlamps to be activated. See Wiper Activated Headlamps.

(Off/On): When operating in AUTO, a momentary turn of the switch to Off/On will turn the Automatic Headlamp System off or back on. For vehicles first sold in Canada, the automatic transmission must be in P (Park) or the manual transmission must have the park brake set, before the Automatic Headlamp System can be turned off.
