Daytime running light system
To make your vehicle more visible to other drivers, the front position lights
turn on automatically whenever the engine is started and the parking brake is
released. Daytime running lights are not designed for use at night.
Headlight control sensor
Automatic light off system
When the light switch is in : The headlights turn off automatically if the
engine switch is turned to ACCESSORY mode or turned off.
When the light switch is in : The headlights and all lights turn off auto-
matically if the engine switch is turned to ACCESSORY mode or turned
off.
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 or .
If any of the doors or trunk lid is kept open, the lights automatically turn off
after 20 minutes.
Light reminder buzzer
A buzzer sounds when the engine switch is turned off or turned to ACCES-
SORY mode and the driver’s door is opened while the lights are turned on.
Automatic headlight leveling system
The level of the headlights is automatically adjusted according to the number
of passengers and the loading condition of the vehicle to ensure that the
headlights do not interfere with other road users. The sensor may not function properly if
an object is placed on the sensor, or any-
thing 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.

In the situations below, the system may not be able to correctly detect the
surrounding brightness levels, and may flash or expose nearby pedestrians
to the high beam. Therefore, you should consider turning the high beams on
or off manually rather than relying on the Automatic High Beam system.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The inside rear view mirror or camera sensor is deformed or dirty.
• Surrounding brightness levels are equal to those of headlights, tail lights
or fog lights.
• Vehicles ahead have headlights that are either switched off, dirty, are
changing color, or have are not aimed properly.
• When driving through an area of intermittently changing brightness and
darkness.
• When frequently and repeatedly driving ascending/descending roads, or
roads with rough, bumpy or uneven surfaces (such as stone-paved roads,
gravel tracks etc.).
• When frequently and repeatedly taking curves or driving on a winding
road.
• There is a highly reflective object ahead of the vehicle, such as a sign or
a mirror.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or titling, due to a flat tire, a trailer being towed etc.
• The driver believes that the high beam may be causing problems or dis-
tress to other drivers or pedestrians nearby.
CAUTION
Limitations of the Automatic High Beam
