■The windshield wiper and washer can be operated when
The power switch is in ON mode.
■Dripping prevention wiper sweep
After performing a 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 170 km/h (106
mph).
■Effects of vehicle speed on wiper operation (vehicles with rain-sensing windshield wip-
ers)
Vehicle speed affects the following even when the wipers are not in AUTO mode.
●Intermittent wiper interval
●Wiper operation when the washer is being used (delay until drip prevention wiper
sweep occurs)
With low speed windshield wiper operation selected, wiper operation will be switched
from low speed to intermittent wiper operation only when the vehicle is stationary.
■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper is turned to AUTO mode while the power switch is in 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 mode.
■When the windshield wipers are in temporary operation (vehicles with rain-sensing
windshield wipers)
AUTO mode cannot be activated even if is pressed.

ate properly when sunlight from the rising or
setting of the sun intermittently strikes the
windshield, or if bugs etc. are present on the
windshield.

fluid may freeze on the windshield and cause low visibility. This may lead to an accident,
resulting in death or serious injury.

When your vehicle is too close to a vehicle ahead, and sufficient automatic
deceleration via the cruise control is not possible, the display will flash and the
buzzer will sound to alert the driver. An example of this would be if another driver
cuts in front of you while you are following a vehicle. Apply the brakes to ensure
an appropriate vehicle-to-vehicle distance.

When constant speed control mode is selected, your vehicle will maintain a set
speed without controlling the vehicle-to-vehicle distance. Select this mode only
when vehicle-to-vehicle distance control mode does not function correctly due

When in constant speed control mode, to return to vehicle-to-vehicle distance con-
trol mode, push the lever forward again and hold for approximately 1 second.
After the desired speed has been set, it is not possible to return to vehicle-to-vehicle
distance control mode.
