■The Automatic High Beam can be operated when
The “START STOP ENGINE” <“POWER”> switch is in IGNITION 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
• When oncoming or preceding vehicles are hidden from sight due to repeatedcurves, road dividers or roadside trees

• When oncoming or preceding vehicles have no lights
●High beam may be turned off if an oncoming vehicle that is using fog lights without
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.
●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 preced- ing vehicles
• The movement and direction of oncoming and preceding vehicles
• When a oncoming or preceding vehicle only has operational lights on one side
• When a oncoming or preceding vehicle is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of the road surface etc.)

4-3. Operating the lights and wipers
●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 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 foglights.
• Vehicles ahead have headlights or tail lights that are either switched off, dirty, are changing color, or are not aimed properly.
• When driving through an area of intermittently changing brightness and dark- ness.
• 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 back of a vehicle ahead is highly reflective, such as a container on a truck.
• The vehicle’s headlights are damaged or dirty, or are not aimed properly.
• The vehicle is listing or titling, 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 distress to other drivers or pedestrians nearby.
■Temporarily lowering sensor sensitivity
The sensitivity of the sensor can be temporarily lowered.
Turn the “START STOP ENGINE” <“POWER”> switch off while the following
conditions are met.
• The headlight switch is in or .
• The headlight switch lever is in high beam position.
• Automatic High Beam switch is on.
Turn the “START STOP ENGINE” <“POWER”> switch to IGNITION ON
mode.

■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper switch is turned to AUTO position while the “START STOP ENGINE”
<“POWER”> switch is in IGNITION ON mode, the wipers will operate once
to show that AUTO mode is activated.
●When the sensor sensitivity ring is turned toward high while in AUTO mode, the
wipers will operate once to indicate that the sensor sensitivity is enhanced.
●If the temperature of the raindrop sensor is 185°F (85°C) or higher, or -22°F
(-30°C) or lower, automatic operation may not occur. In this case, operate 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 washer fluid in the wind-
shield 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.
CAUTION
■Caution regarding the use of windshield wipers in AUTO mode (vehicles with
rain-sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or the
windshield is subject to vibration in AUTO mode. Take care that your fingers or
anything else 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 windshield becomes warm.
The fluid may freeze on the windshield and cause low visibility. This may lead to an
accident, resulting in death or serious injury.
