5Increases the rain-sensing wind-
shield wiper sensitivity
6 Decreases the rain-sensing
windshield wiper sensitivity
7 Washer/wiper dual opera-
tion
Pulling the lever operates the wipers
and washer.
Wipers will automatically operate a cou-
ple of times after the washer squirts.
Vehicles with headlight cleaners: When
the headlights are on and the lever is
pulled and held, the headlight cleaners
will operate once. After this, the head-

The engine switch is in ON.
■Effects of vehicle speed on wiper
operation (vehicles with rain-sens- ing windshield wipers)
Vehicle speed affects the Intermittent
wiper interval.
■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 wind- shield.
●If the wiper is turned to AUTO mode while the engine switch is in ON, the
wipers will operate once to show that
AUTO mode is activated.
●If the temperature of the raindrop sen-
sor is 85°C (185°F) or higher, or -15°C (5°F) or lower, automatic operation
may not occur. In this case, operate
the wipers in any mode other than AUTO mode.

shield wipers will operate in high speed
operation. After the vehicle is stopped, operation will return to normal when the
engine switch is turned to ON, or opera-
tion will stop when the driver’s door is opened.
