Automatic High Beam
Push the lever away from you with
the headlight switch in the
position.
The Automatic High Beam indica-

automatically turned on (after approximately 1 second):
● Vehicle speed is above appr oximately 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.

● Vehicle speed drops below approximately 20 mph (32 km/h).
● The area ahead of the vehicle is not dark.
● Oncoming or preceding vehicles have headlights or tail lights
turned on.

preceding vehicles, etc., and au tomatically turns high beam on
or off as necessary.

• 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
without using the headlights is detected.

4-3. Operating the lights and wipers
●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 beam 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 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 are not aimed properly.
• When driving through an area of in termittently 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 lifting or tilting, due to a flat tire, a trailer being towed etc.
• 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 dis- tress to other drivers or pedestrians nearby.
■ When the warning message is shown on the multi-information display
P. 562
■ Temporary lowering sensor sensitivity
The sensitivity of the sensor can be temporarily lowered.
To lower the sensitivity, push and hold on the inside rear view mirror for
15 to 20 seconds, and release. The indicator light on the inside rear view mir-
ror will flash to indicate that the sensitivity has been lowered.
When the engine switch is turned to the “LOCK” position (vehicles without a
smart key system) or turned off (vehicles with a smart key system), the sensi-
tivity will be returned to its normal level.
■ Customization
The Automatic High Beam can be turned off.
