WARNING
■Before using the LDA system
Do not rely solely on the LDA system. The LDA system does not drive the
vehicle automatically, nor does it reduce the amount of care you need to
take. As such, the driver must always assume full responsibility for under-
standing his/her surroundings, for operati ng the steering wheel to correct
the driving line, and for driving safely.
Inappropriate or negligent driving could lead to an accident.
■ To avoid operating the LDA by mistake
Switch the LDA system off using the LDA switch when not in use.

● 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 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 front sensor is deformed or dirty.
• The front sensor temperature is extremely high.
• Surrounding brightness levels are equal to those of headlights, tail lights
or fog lights.
• 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
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 back of a vehicle ahead is highly reflective, such as a container on a
truck.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or titling, due to a flat tire, a trailer being towed, etc.
• The driver believes that the high beam may be causing problems or dis-
tress to other drivers or pedestrians nearby.

monochrome display)
It may indicate a malfunction in the system. Contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
