■Daytime running light system
●To make your vehicle more visible to other drivers, the headlights turn on auto-
matically (at a reduced intensity) whenever the engine is started and the parking
brake is released. Daytime running lights are not designed for use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the switch.
●Compared to the headlights, the daytime running light system offers greater
durability and consumes less electricity, so it can help fuel economy.
■Headlight control sensor
■Automatic light off system
●When only the tail lights come on: The parking/front side marker, tail, license
plate and fog lights turn off if the “ENGINE START STOP” switch is turned to
ACCESSORY mode or turned off an d the driver’s door is opened.
●When the headlights come on: The headlights, parking/front side marker, tail,
license plate and fog lights turn off 30 seconds after a door or the glass hatch is
opened and closed. (The lights turn off immediately if on the key is
pressed after all the doors are locked.)
To turn the lights on again, turn the “ENGINE START STOP” switch to IGNITION
ON mode, or turn the light switch off once and then back to
or .
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.
