5-3. Operating the lights and wipers
Driving
■The windshield wipers and washer can be operated when
The power switch is in ON.
■Effects of vehicle speed on wiper operation
With low speed windshield wiper opera-
tion selected, wiper operation will be switched from low speed to intermittent wiper operation when the vehicle is sta-
tionary. (However, when the sensor sen- sitivity is adjusted to the highest level, the mode will not switch.)
■Raindrop sensor
●The raindrop sensor judges the amount of raindrops. An optical sen-
sor 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 the “AUTO” position while the power switch is in ON, the wipers will operate
once to show that “AUTO” mode is activated.
●If the wiper sensitivity is adjusted to higher, the wiper may operate once to
indicate the change of sensitivity.
●If the temperature of the raindrop sen-
sor is 85°C (185°F) or higher, or -15°C (5°F) or lower, the automatic opera-tion may not occur. In this case, oper-
ate 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 windshield washer fluid reservoir.
■Washer nozzle heaters (if
equipped)
The washer nozzle heaters operate to prevent frozen nozzle when the outside
temperature is 5°C (41°F) or less and the power switch is in ON.
WARNING
■Caution regarding the use of
windshield wipers in “AUTO” mode
The windshield wipers may operate
unexpectedly if the sensor is touched or the windshield is subject to vibra-tion in “AUTO” mode. Take care that
your fingers or anything else does not become caught in the windshield wip-ers.
■Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes warm. The fluid may freeze on the
windshield and cause low visibility. This may lead to an accident, result-ing in death or serious injury.
■When the washer nozzle heaters are operating (if equipped)
Do not touch the area around the washer nozzle, as they can become very hot and burn you.
NOTICE
■When the washer fluid tank is
empty
Do not operate the switch continually as the washer fluid pump may over-
heat.
