running lights turn on automatically whenever the engine is started with the headlight
switch off (for Canada) or in the or “AUTO” position and the parking brake
released. (Illuminate brighter than the par king lights.) Daytime running lights are not
designed for use at night.

When the light switch is in , or : The headlights and tail lights turn off 30
seconds after the engine switch is turned to ACCESSORY mode or turned off and a
door is opened and all of the doors and trun k are closed. (The lights turn off immediately

gers and the loading condition of the vehicle to ensure that the headlights do not inter-
fere with other road users. The sensor may not function properly if an
object is placed on the sensor, or anything that
blocks the sensor is affixed to the windshield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.
