vehicle is moving.)
Vehicles with headlight cleaners: When the
engine switch is in IGNITION ON mode
and the headlights are on, if the lever is
pulled, the headlight cleaners will operate
once. After this, the headlight cleaners will
operate every 5th time the lever is pulled.
The windshield wiper and washer can be

operated when
The engine switch is in IGNITION ON
mode.
Effects of vehicle speed on wiper opera-
■
tion (vehicles with rain-sensing wind-
shield wipers)
Even when the wipers are not in AUTO
mode, vehicle speed affects the time until
the drip prevention wiper sweep occurs.
With low speed windshield wiper operation
selected, wiper operation will be switched
from low speed to intermittent wiper opera-
tion only when the vehicle is stationary.
(However, when the sensor sensitivity is
adjusted to the highest level, the mode can-
not be switched.)
■ Raindrop sensor (vehicles with rain-
sensing windshield wipers)
● The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs etc. are
present on the windshield.
If the wiper is turned to AUTO position
●
while the engine switch is in IGNITION
ON mode, the wipers will operate once
to show that AUTO mode is activated.
If the temperature of the raindrop sensor
●
is 85°C (185°F) or higher, or -30°C (-
22°F) or lower, automatic operation may
not occur. In this case, operate the wipers
in any mode other than AUTO.

■
wiper stop function (vehicles with rain-
sensing windshield wipers)
When AUTO is selected and the wind-
shield wipers are operating, if a front door is
opened while the vehicle is stopped and the
P position is selected, operation of the
windshield wipers will be stopped to pre-
vent anyone near the vehicle from being
sprayed by water from the wipers. When
the front door is closed, wiper operation will
resume.
To protect the windshield wipers
■
If movement of the windshield wipers is
largely restricted by a foreign object such as
snow, the operation of the windshield wip-
ers may be stopped automatically to pro-
tect the windshield wipers. In this case, turn
the windshield wiper switch off and remove
the foreign object, and then use the wind-
shield wipers.
■ When stopping the engine in an emer-
gency while driving
If the windshield wipers are operating when
the engine is stopped, the windshield wipers
will operate in high speed operation. After
the vehicle is stopped, operation will return
to normal when the engine switch is turned
to IGNITION ON mode, or operation will
stop when the driver's door is opened.
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.
