ers and washer.
(After operating several times, the wipers operate once more time
after a short delay to prevent drip-
ping. However, the dripping preven-
tion does not operate while the
vehicle is moving.)

■The windshield wiper and
washer can be operated when
The power switch is in ON.
■Effects of vehicle speed on
wiper operation (vehicles with
rain-sensing windshield wipers)
Even when the wipers are not in
AUTO mode, vehicle speed affects
the time until the drip prevention
wiper sweep occurs.
With low speed windshield wiper
operation selected, wiper operation
will be switched fro m low speed to
intermittent wiper operation only
when the vehicle is stationary.
(However, when the sensor sensitiv-
ity is adjusted to the highest level,
the mode cannot be switched.)
■Raindrop sensor (vehicles with
rain-sensing windshield wipers)
●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 b ugs, etc., are
present on the windshield.
●If the wiper is turned to AUTO

2384-3. Operating the lights and wipers
Owners Manual_USA_M0C043_enmode while the powe
r switch is in
ON, the wipers will operate once
to show that AUTO mode is acti-
vated.
●If the temperature of the raindrop
sensor is 185°F (85°C) or higher,
or 5°F (-15°C) or lower, automatic
operation may not occur. In this
case, operate the wipers in any
mode other than AUTO mode.
■If no windshield washer fluid
sprays
Check that the wash er nozzles are
not blocked if there is washer fluid in
the windshield washer fluid reser-
v oi r.
WARNING
■Caution regarding the use of
windshield wipers in AUTO
mode (vehicles with rain-
sensing windshield wipers)
The windshield wipers may oper-
ate unexpectedly if the sensor is
touched or the windshield is sub-
ject to vibration in AUTO mode.
Take care that your fingers or any-
thing else 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 windshield
becomes warm. The fluid may
freeze on the windshield and
cause low visibility. This may lead
to an accident, resulting in death
or serious injury.
NOTICE
■When there is no washer fluid
spray from the nozzle
Damage to the washer fluid pump
may be caused if the lever is
pulled toward you and held con-
tinually.
■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 will be
damaged.
■To prevent 12-volt battery dis-
charge
Do not leave the wipers on longer
than necessary when the hybrid
system is off.

If the message does not disappea r, contact your Toyota dealer.
• When the temperature around the radar sensor is outside of the opera-
tional range, such as when the vehicle is in the sun or in an e xtremely cold
environment

as when driving in the dark, sno w, or fog, or when bright lights are shining
into the front camera

Driving
• The steering wheel is tur ned sharply or abruptly.
●Emergency steering assist
When the turn signal lights are flashing, emergency steering as sist will not
operate in case of an emergency.
The emergency steeri ng assist will be disabl ed automatically when the sys-
tem judges that a trailer is connected.
If any of the following occur wh ile the emergency steering assi st function is
operating, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is tur ned sharply or abruptly.
• The brake pedal is depressed.
●Intersection right/left turn assistance (pre-collision warning)
When the turn signal lights are not flashing, support for turning left or right at
an intersection which targets on coming vehicles does not work.
When the system judges that a trailer is detected, intersection support is dis-
abled for vehicles and pedestrians.
●Intersection right/left turn assistance (pre-collision braking)
When the turn signal lights are not flashing, support for turning left or right at
an intersection which targets on coming vehicles does not work.
When the system judges that a trailer is detected, intersection support is dis-

system and steering assist func-
tion when the vehicle is lifted
unless using a Toyota official lift
up kit up to 4 in. (101 mm),
including tire height. Aftermar-
ket lift kits may degrade system
performance.

●When the vehicle is lifted up,
except in the following cases.
• When using a Toyota official lift kit up to 4 in. (101 mm), includ-
ing tire height. Aftermarket lift
kits may degrade system perfor-
mance.
