2-3. Operating the lights and windshield 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 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 driver believes that the high beam may be causing problems or distress to
other drivers or pedestrians nearby.
If the Automatic High Beam indicator flashes
■
It may indicate a malfunction in the system. Contact your Lexus dealer.
Temporary lowering sensor sensitivity
■
The sensitivity of the sensor can be temporarily lowered.
To lower the sensitivity, push and hold the "AUTO" button on the inside rear view
mirror for 15 to 20 seconds, and release. The indicator light on the inside rear view
mirror will flash to indicate that the sensitivity has been lowered.
When the "POWER" switch is turned off, the sensitivity will be returned to its nor-
mal level.
