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): Turns on the Daytime Running Lamps (DRL) during daytime, and the headlamps, parking lamps, and taillamps at night.

(Off/On): This position is the momentary Off/On switch for the Automatic Headlamp System. In Canada; this only works when the vehicle is in PARK (P).

When operating in AUTO, a momentary turn of the switch to off/on will turn off the Automatic Headlamp System. Turn the switch to off/on again will turn the Automatic Headlamp System back on. The Automatic Headlamp System is always turned on at the beginning of an ignition cycle.

The following charts show the condition of the vehicle's exterior lamps when the transaxle is not in PARK (P) and the switch is moved to each position:
