1664-3. Operating the lights and wipers
6Increases the sensitivity
7 Decreases the sensitivity
8 Washer/wiper dual opera-
tion
Pulling the lever operates the wipers and
washer.
The wipers will automatically operate a
couple of times after the washer squirts.
(After operating several times, the wipers
operate once more time after a short delay
to prevent dripping. However, the dripping
prevention does not operate while the
vehicle is moving.)
■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 switch 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 185°F (85°C) or higher, or -22°F (-
30°C) 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 if there is washer fluid in the wind-
shield washer fluid reservoir.
■Front door opening linked windshield
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
