WARNING
■When washing the vehicle
Do not apply water to the inside of
the engine compartment. Doing
so may cause the electrical com-
ponents, etc. to catch fire.
■Precautions regarding the
exhaust pipe
Exhaust gases 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 hot
exhaust pipe can cause burns.
■When cleaning the windshield
(vehicles with rain-sensing
windshield wipers)
Set the wiper switch to off.
If the wiper switch is in “AUTO”,
the wipers may operate unexpect-
edly in the following situations,
and may result in hands being
caught or other serious injuries
and cause damage to the wiper
blades.
