■

The windshield wiper and washer can be operated when

The °ENGINE START STOP± switch is in IGNITION ON mode.

■

Dripping prevention wiper sweep

After washing and wiping operation several times, the wipers operate one more

time after a short delay to prevent dripping.

However, the last sweep will not happen if the vehicle is traveling above 106 mph

(170 km/h).

■

Effects of vehicle speed on wiper operation

Vehicle speed affects the following even when the wipers are not °AUTO± mode.

●

Intermittent wiper interval (

mode)

●

Wiper operation when the washer is being used (delay until drip prevention

wiper sweep occurs)

With

selected, wiper operation will be switched from low speed to intermit-

tent wiper operation only when the vehicle is stationary.

■

Rain drop sensor (vehicles equipped with rain-sensing windshield wipers)

●

If the wiper switch is turned to the °AUTO± position while the °ENGINE START

STOP± 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 167²F (75²C) or higher, or 14²F

(-10²C) or lower, automatic operation may not occur. In this case, operate the

wipers in any mode other than °AUTO±.

●

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.
