There is a malfunction in the system
*1: The system judges a person of adult size as an adult. When a smaller
adult sits in the front passenger seat, the system may not recognize
him/her as an adult depending on his/her physique and posture.
*2: In the event the front passenger is wearing a seat belt.
*3: In the event the front passenger does not wear a seat belt.
*4: For some children, child in seat, child in booster seat or child in convert-ible seat, the system may not recognize him/her as a child. Factors
which may affect this can be the physique or posture.
*5: Never install a rear-facing child restraint system on the front passengerseat. A forward-facing child restraint system should only be installed on
the front passenger seat when it is unavoidable. ( →P. 59)
*6: In case the indicator light is not illuminated, consult this manual on how
to install the child restraint system properly. ( →P. 58)

WARNING
■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning lights not
come on when you start the fuel cell system, this could mean that these
systems are not available to help protect you in an accident, which could
result in death or serious injury. Have the vehicle inspected by your Toyota
dealer immediately if this occurs.

Driving

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 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, 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 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 tilting, 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.
WARNING
■Limitations of the Automatic High Beam
Do not rely on the Automatic High Beam. Always drive safely, taking care to
observe your surroundings and turning high beam on or off manually if nec-
essary.
