8 Washer/wiper dual opera-
tion
Pulling the lever operates the wipers and
washer.
The wipers will automatically operate a
couple of times after the washer squirts.
(After operating several times, the wipers
operate once more time after a short delay
to prevent dripping. However, the dripping
prevention does not operate while the
vehicle is moving.)
QThe windshield wiper and washer can be
operated when
The power switch is in ON mode.
QEffects of vehicle speed on wiper opera-
tion (vehicles with rain-sensing wind-
shield 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
from low speed to intermittent wiper opera-
tion only when the vehicle is stationary.
(However, when the sensor sensitivity is
adjusted to the highest level, the mode can-
not be switched.)
QRaindrop sensor (vehicles with rain-
sensing windshield wipers)
OThe 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.
OIf the wiper switch is turned to AUTO
position while the power switch is in ON
mode, the wipers will operate once to
show that AUTO mode is activated.
OIf the temperature of the raindrop sensor
is 185°F (85°C) or higher, or -22°F (-
30°C) or lower, automatic operation
may not occur. In this case, operate the
wipers in any mode other than AUTO.
QIf no windshield washer fluid sprays
Check that the washer nozzles are not
blocked if there is washer fluid in the wind-
shield washer fluid reservoir.
QFront door opening linked windshield
wiper stop function (vehicles with rain-
sensing windshield wipers)
When AUTO is selected and the wind-
shield wipers are operating, if a front door is
opened while the vehicle is stopped and the
P position is selected, operation of the
windshield wipers will be stopped to pre-
vent anyone near the vehicle from being
sprayed by water from the wipers.
When the front door is closed, wiper opera-

1724-3. Operating the lights and wipers
tion will resume.
QTo protect the windshield wipers
If movement of the windshield wipers is
largely restricted by a foreign object such
as snow, the operation of the windshield
wipers may be stopped automatically to
protect the windshield wipers. In this case,
turn the windshield wiper switch off and
remove the foreign object, and then use the
windshield wipers.
QWhen stopping the hybrid system in an
emergency while driving
If the windshield wipers are operating when
the hybrid system is stopped, the windshield
wipers will operate in high speed operation.
After the vehicle is stopped, operation will
return to normal when the power switch is
turned to ON mode, or operation will stop
when the driver’s door is opened.
When the windshield wipers are not
being used, they retract to below the
hood. To enable the windshield wipers
to be lifted when parking in cold condi-
tions or when replacing a windshield
wiper insert, change the rest position of
the windshield wipers to the service
position using the wiper lever.
QRaising the wipers to the service
position
Within approximately 45 seconds of
turning the power swit ch off, move the
wiper lever to the (U.S.A.) or
(Canada) position and hold it for
approximately 2 seconds or more.
The wipers will move to the service posi-
tion.
WARNING
QCaution regarding the use of wind-
shield wipers in AUTO mode (vehi-
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 or anything else do not become
caught in the windshield wipers.
QCaution 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
QWhen 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 continually.
QWhen a nozzle becomes blocked
In this case, contact your Lexus dealer.
Do not try to clear it with a pin or other
object. The nozzle will be damaged.
QTo prevent 12-volt battery discharge
Do not leave the wipers on longer than
necessary when the hybrid system is off.

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 seri-
ous injury.
OUse tires of the specified size.
OMaintain the recommended level of air
pressure.
ODo not drive in excess of 75 mph (120
km/h), regardless of the type of snow
tires being used.
OUse snow tires on all, not just some
wheels.
QDriving with tire chains (vehicles with
17-inch tires)
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in the vehicle
being unable to be driven safely, and may
cause death or serious injury.
ODo not drive in excess of the speed
limit specified for the tire chains being
used, or 30 mph (50 km/h), which-
ever is lower.
OAvoid driving on bumpy road surfaces
or over potholes.
OAvoid sudden acceleration, abrupt
steering, sudden braking and shifting
operations that cause sudden engine
braking.
