● If the temperature of the raindrop sensor is 85°C (185°F) or higher, or
-40°C (-40°F) or lower, automatic operation may not occur. In this case,
operate the wipers in any mode other than AUTO.
■ If no windshield washer fluid sprays
Check that the washer nozzles are not blocked and if there is washer fluid in
the windshield washer fluid reservoir.
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 care that your fin-
gers 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 winds hield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.
NOTICE
■ When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■ When the washer fluid tank is empty
Do not use the washer when the washer fluid tank is empty. This may cause

■ When changing the tires
Depending on the tires used, sufficient performance may not be maintain-
able.
■ Warning messages for the LDA system
Warning messages are used to indicate a system malfunction or to inform
the driver of the need for caution while driving.
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 operating 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.
NOTICE
■ To prevent damage to or incorrect operation of the LDA system
● Do not modify the headlights or attach stickers to the surface of the lights.
● Do not modify the suspension. If your suspension needs repairs, contact
any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional.
● Do not install or place anything on the hood or the grille. Also, do not install
a grille guard (bull bars, kangaroo bar etc.).
