When the windshield wipers are in tem-
porary operation (vehicles with
rain-sensing windshield wipers)
AUTO mode cannot be activated even if is

WARNING
■
Caution regarding the use of wind-
shield 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 fingers
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 windshield
and cause low visibility. This may lead to
an accident, resulting in death or serious
injury.
NOTICE

from the nozzle
Damage to the washer fluid pump may
be caused if the lever is pulled toward
you and held continually.
■ When a nozzle becomes blocked
In this case, contact your Lexus dealer.
Do not try to clear it with a pin or other
object. The nozzle will be damaged.
