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 sp eed 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”.*: It may be located on the opposite side
depending on the target region.
■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.

Driving
4 Washer/wiper dual oper-
ation
Pushing the lever operates the wiper

The wiper will automatically operate a
couple of times after the washer
squirts.
■The rear window wiper and washer
can be operated when
The power switch is in ON.
■If no washer fluid sprays
Check that the wash er nozzle is not
blocked if there is washer fluid in the
washer fluid reservoir.
■Back door opening linked rear win - dow wiper stop function
When the rear window wiper is operat -
ing, if the back door is opened while the vehicle is stopped, o peration of the rear
window wiper will be stopped to prevent
anyone near the vehicle from being sprayed by water f rom the wiper. When
the back door is closed, wiper operation
will resume.*
*: The setting must be customized at
any authorized Toy ota retailer or
Toyota authorized repairer, or any reli -
able repairer.
■Reverse-linked rear window wiper function
When the shift lever is shifted to R when
the front wipers are operating, the rear window wiper will operate once.
■Customization
Setting of the reverse-linked function can be changed.
(Customizable features: →P.637)
NOTICE
■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 any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.
■To prevent 12-volt battery dis - charge
Do not leave the wiper on longer than
necessary when the hybrid system is off.

Driving
5-6.Driving tips
 Use fluids that are appropriate to
the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Power control unit coolant
• Washer fluid
 Have a service technician
inspect the condition of the 12-
volt battery.
 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 chains match the
size of the tires.*
*: Tire chains cannot be mounted on
vehicles with 235/55R19 tires.
Winter driving tips
Carry out the necessary prepa -
rations and inspections before
driving the vehicle in winter.
Always drive the vehicle in a
manner appropriate to the pre -
vailing weather conditions.
Pre-winter preparations
WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of
vehicle control and cause death or serious injury.
●Use tires of the specified size.
●Maintain the recommended level of air pressure.
●Do not drive at speeds in excess of the speed limit or the speed limit
specified for the snow tires being
used.
●Use snow tires on all, not just some
wheels.
■Driving with tire chains (except
235/55R19 tires)
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in the vehi - cle being unable to be driven safely,
and may cause death or serious
injury.
●Do not drive in excess of the speed
limit specified for the tire chains being used, or 50 km/h (30 mph),
whichever is lower.
●Avoid driving on bumpy road sur -
faces or over potholes.
●Avoid sudden acceleration, abrupt
steering, sudden br aking and shift-
ing operations that cause sudden engine braking.
●Slow down sufficiently before enter - ing a curve to ensure that vehicle
control is maintained.
●Do not use LTA (Lane Tracing
Assist) system (if equipped).
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tires from any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer or legitimate tire retailers.
This is because the removal and
attachment of snow tires affects the operation of the tire pressure warning
valves and transmitters.
