Automatic High Beam∗∗

brightness of streetlights, the lights of oncoming and preceding vehicles,
etc., and automatically turns high beam on or off as necessary.

Turn the headlight switch to the position.
Push the lever away from you.
The Automatic High Beam indi-
cator will come on when the
headlights are turned on auto-
matically to indicate that the sys-
tem is active.

■The Automatic High Beam can be operated when
The “POWER” switch is ON mode.
■Camera sensor detection information
●High beam may not be automatically turned off in the following situations:
• When oncoming vehicles suddenly appear from a curve.
• When the vehicle is cut in front of by another.
●High beam may be turned off if an oncoming vehicle that is using fog lights with-
out using the headlights is detected.
●House lights, street lights, red traffic signals, and illuminated billboards or signs
may cause the high beam to turn off.

automatically turned on (after approximately 1 second):
● Vehicle speed is above approximately 20 mph (32 km/h).
● The area ahead of the vehicle is dark.
● There are no oncoming or preceding vehicles with headlights or
tail lights turned on.

●The following factors may affect the amount of time taken to turn high beam on
or off:
• The brightness of headlights, fog lights, and tail lights of oncoming and pre-ceding vehicles
• Road conditions (wetness, ice, snow etc.)
• The number of passengers and amount of baggage
●High beam may be turned on or off when unexpected by the driver.
●In the situations below, the system may not be able to correctly detect the sur-
rounding 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 chang-
ing 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 mir- ror.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or tilting, due to a flat tire, a trailer being towed etc.
• The Automatic High Beam indicator is flashing.
• The high beam and low beam are repeatedly being switched between in an abnormal manner.
• The driver believes that the high beam may be causing problems or distress to other drivers or pedestrians nearby.
