5-3. Operating the lights and wipers
■The windshield wipers and washer can be operated when
The power switch is in ON mode.
■ Dripping prevention wiper sweep (vehicles with rain-sensing win dshield
wipers)
After washing and wiping operation several times, the wipers op erate one
more time after a short delay to prevent dripping. However, thi s function will
not operate while driving.
■ Effects of vehicle speed on wip er operation (vehicles with rain-sensing
windshield wipers)
Vehicle speed affects the Intermittent wiper interval.
■ Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper switch is turned to the “AUTO” position while the power switch is
in ON mode, the wipers will operate once to show that AUTO mode is acti-
vated.
● If the wiper sensitivity is adjusted to higher, the wiper may o perate once to
indicate the change of sensitivity.
● If the temperature of the raindrop sensor is 185 F (85 C) or higher, or 14 F
(-10 C) or lower, automatic operation may not occur. In this case, o perate
the wipers in any mode other than AUTO mode.
■ If no windshield washer fluid sprays
Check that the washer nozzles are not blocked, if there is wash er fluid in the
washer fluid tank.
■ Customization
Settings of AUTO mode operation can be changed.
(Customizable features: P. 736)
●
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.

WARNING
■Caution regarding the use of win dshield wipers in AUTO mode (ve hi-
cles with rain-sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or
the windshield is subject to vibration in AUTO mode. Take care that your fin-
gers, etc. do not become caught in the windshield wipers.
■ Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshie ld becomes
warm. The fluid may freeze on the windshield and cause low visi bility. This
may lead to an accident, resulting in death or serious injury.
NOTICE
■ When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■ When the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may over-
heat.
■ When a nozzle becomes blocked
In this case, contact your Toyota dealer.
Do not try to clear it with a pin or other object. The nozzle w ill be damaged.
■ To prevent 12-volt b attery discharge
Do not leave the wipers on longer than necessary when the hybri d system
is off.

Winter driving tips
●Use fluids that are appropriate t o the prevailing outside tempera-
tures. • Engine oil
• Engine/power control unit coolant
• Washer fluid
● Have a service technician inspect the condition of the 12-volt bat-
tery.
● Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the front tires.
Ensure that all tires are the same size and brand, and that cha ins match
the size of the tires.
Perform the following accordi ng to the driving conditions:
● Do not try to forcibly open a window or move a wiper that is fr ozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to p revent it from freezing.
● To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
● Check for and remove any excess ic e or snow that may have accu-
mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.
● Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
