to “DRL OFF” position. ●

Automatic headlight leveling system (if equipped)
The level of the headlights is automatically ad justed according to the number of passen-

fere with other road users. ■
Light reminder buzzer
A buzzer sounds when the power switch is turned off or turned to ACCESSORY mode
and the driver’s door is opened while the lights are turned on. ■
12-volt battery-saving function
In order to prevent the 12-volt battery of the vehicle from discharging, if the headlights
and/or tail lights are on when the power swit ch is turned off the 12-volt battery saving
function will operate and automatically turn off all the lights after approximately 20 min-
utes. When the power switch is turned to ON mode, the 12-volt battery-saving function
will be disabled.
When any of the following are performed, the 12-volt battery-saving function is canceled
once and then reactivated. All the lights w ill turn off automatically 20 minutes after the
12-volt battery-saving function has been reactivated: ●
When the headlight switch is operated ●
When a door is opened or closedThe 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.
