NOTICE
■
To prevent battery discharge
Do not leave the lights on longer than necessary when the engine is not running.
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.
