CAUTION
Caution regarding the use of windshield wiper in “AUTO” mode (vehi-
cles with a rain-sensing windshield wiper)
The windshield wiper may operate unexpectedly if the sensor is touched or
the windshield is subject to vibration in “AUTO” mode. Take care that your
fingers etc. do not become caught in the windshield wiper.
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.
NOTICE
When the windshield is dry
Do not use the wiper, as they may damage the windshield.
When the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may over-
heat.

CAUTION
When cleaning the windshield (vehicles with a rain-sensing windshield
wiper)
When the upper part of the windshield where the raindrop sensor is
located is touched by hand
When a wet rag or similar is held close to the raindrop sensor
If something bumps against the windshield
If you directly touch the raindrop sensor body or if something bumps into
the raindrop sensor
When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components etc. to catch fire.
Precautions regarding the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has cooled
sufficiently, as touching a hot exhaust pipe can cause burns.
Set the wiper switch to off.
If the wiper switch is in “AUTO”, the wiper
may operate unexpectedly in the follow-
ing situations, and may result in hands
being caught or other serious injuries and
cause damage to the wiper blades.Off
