Washer/wiper dual opera-
tion
Pulling the lever operates the wipers and
washer.
(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.)
Vehicles with headlight cleaners:
When the power switch is in 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 power switch is in ON mode.
■ Effects of vehicle speed on wiper opera-
tion
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
● 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.
