In the situations below, the system may not be able to correctl y detect the
surrounding brightness levels, and may flash or expose nearby p edestrians
to the high beam. Therefore, you should consider turning the hi gh 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 camera sensor is deformed or dirty.
• The camera sensor temperature is extremely high.
• Surrounding brightness levels are equal to those of headlights , tail lights
or fog lights.
• Vehicles ahead have headlights that are either switched off, d irty, are
changing color, or 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 w inding
road.
• There is a highly reflective object ahead of the vehicle, such as a sign or a mirror.
• The back of a vehicle ahead is highly reflective, such as a co ntainer on a
truck.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or tilting, due to a flat tire, a trailer being towed, etc.

Washer/wiper dual oper-
ation
Pulling the lever operates the
wipers and washer.
Wipers will automatically operate a
couple of times after the washer
squirts.
■ The windshield wipers and washers can be operated when
The power switch is in ON mode.
■ Effects of vehicle speed on wiper operation
Vehicle speed affects the Intermittent wiper interval.
■ Raindrop sensor
●If the wiper switch is turned to the “AUTO” position while the power switch is
in ON mode, the wipers will operate once to show that “AUTO” mo de is acti-
vated.
● If the temperature of the raindrop sensor is 194 F (90 C) or higher, or 5 F
(-15 C) or lower, automatic operation may not occur. In this case, o perate
the wipers in any mode other than “AUTO” mode.
■ If no windshield washer fluid sprays
Check that the washer nozzles are not blocked, if there is wash er fluid in the
windshield washer fluid reservoir.
● The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs, etc.,
are present on the windshield.
WARNING
■Caution regarding the use of windshield wipers in “AUTO” mode
The windshield wipers may operate unexpectedly if the sensor is touched or
the windshield is subject to vibration in “AUTO” mode. Take car e that your
fingers, etc., do not become caught in the windshield wipers.
■ Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshie ld becomes
warm. The fluid may freeze on the windshield and cause low visi bility. This
may lead to an accident, resulting in death or serious injury.
