Daytime running light system

■
To make your vehicle more visible to other drivers during daytime driving, the daytime
●
running lights turn on automatically whenever the engine is started and the parking
brake is released. (Illuminate brighter than the parking lights.) 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 turning on the headlights, the daytime running light system offers greater
●
durability and consumes less electricity, so it can help improve fuel economy.

Headlight control sensor

■
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.

Automatic light off system

■
When the headlights are on: The headlights and tail lights turn off 30 seconds after a
●
door is opened and closed if the engine switch has been switched to ACCESSORY or
OFF mode.
When only the tail lights are on: The tail lights turn off automatically if the engine switch
●
is switched to ACCESSORY or OFF mode and driver' s door is opened.
To turn the lights on again, turn the engine switch to IGNITION ON mode, or turn the
light switch off once and then back to
LX570_OM_OM60N01U_(U)
or position.
