Driving
8 Windshield washer/wiper
dual operation
Pulling the lever operates the windshield
wipers and washer.
(After operating severa l 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.)
Vehicles with headlight cleaners:
When the engine switch is in IGNITION
ON mode and the headlights are on, if the
lever is pulled, the headlight cleaners will
operate once. After this, the headlight
cleaners will operate every 5th time the
lever is pulled.
9* Rear camera washer opera-
tion
Pushing the lever operates the rear cam-
era washer and cleans the rear camera and
the camera for the Digital Rearview Mirror.
*: Vehicles with Digital Rearview Mirror
■The windshield wiper and washer can be
operated when
The engine switch is in IGNITION ON
mode.
■Effects of vehicle speed on wiper opera-
tion
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 operat ion 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.)
■Raindrop sensor
●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.
●If the wiper is turned to AUTO mode
while the engine swit ch is in IGNITION
ON mode, the wipers will operate once
to show that AUTO mode is activated.
●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 washer fluid sprays
Check that the washer nozzles are not
blocked if there is wash er fluid in the washer
fluid reservoir.
■Front door opening linked windshield
wiper stop function
When is selected and the windshield
wipers are operating, if a front door is
opened while the vehicle is stopped and the
P shift position is sele cted, operation of the
windshield wipers will be stopped to pre-
vent anyone near th e vehicle from being
sprayed by water from the wipers. When
the front door is closed, wiper operation will
resume.
■When stopping the engine in an emer-
gency while driving
If the windshield wipe rs are operating when

1984-3. Operating the lights and wipers
the engine is stopped, the windshield wipers
will operate in high speed operation. After
the vehicle is stopped, operation will return
to normal when the engine switch is turned
to IGNITION ON mode, or operation will
stop when the driver’s door is opened.
■Outside rear view mirror defogger acti-
vation linked to windshield wiper opera-
tion
The outside rear view mirror defoggers
automatically turn on when you operate the
windshield wipers.
The outside rear view mirror defoggers
automatically turn off approximately 15
minutes after the wipers stop.
For details about the outside rear view mir-
ror defoggers:  P.324When 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.
■Raising the wipers to the service
position
Within approximately 45 seconds of
turning the engine switch 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
■Caution regarding the use of wind-
shield wipers in AUTO mode
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 fingers
or anything 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 continually.
■When 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.

•Washer fluid
Have a service technician inspect
the condition of the battery.
 Have the vehicle fitted with four
snow tires or purchase a set of tire
chains for the rear tires.
*
Ensure that all tires are the specified size
and brand, and that chains match the size
of the tires.

Preparation for winter
WARNING
■Driving with snow tires
Observe the following precautions to
reduce the risk of accidents.

vehicle control and cause death or seri-
ous injury.
●Use tires of the specified size.
●Maintain the recommended level of air
pressure.
●Do not drive in excess of 75 mph (120
km/h), regardless of the type of snow
tires being used.
●Use snow tires on all, not just some
wheels.
■When installing tire chains
Before installing tire chains, make sure to
disable all functions of the vehicle height

air suspension. Otherwise, the vehicle
height may change while installing the
tire chains and part or your body may be
caught under the vehicle, possibly caus-
ing injury. ( P.303)
■Driving with tire chains
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.
●Do 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.
●Avoid driving on bumpy road surfaces
or over potholes.
●Avoid sudden acceleration, abrupt
steering, sudden br aking and shifting
operations that cause sudden engine
braking.
●Slow down sufficiently before entering
a curve to ensure that vehicle control is
maintained.
●Do not use LTA (Lane Tracing Assist)
system.

a dangerous loss of braking efficiency. Use
only newly opened brake fluid.
If any washer does not work or the
warning message appears on the
multi-information display, the washer
tank may be empty. Add washer fluid.
WARNING
■When filling the reservoir
Take care as brake fluid can harm your
hands and eyes and damage painted sur-
faces.
If fluid gets on your hands or in your eyes,
flush the affected area with clean water
immediately.
If you still experience discomfort, see a
doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go
down slightly as the brake pads wear out
or when the fluid level in the accumulator
is high.
If the reservoir need s frequent refilling,
there may be a serious problem.
Adding the washer fluid

■When adding washer fluid
Do not add washer fluid when the engine
is hot or running as washer fluid contains
alcohol and may catch fire if spilled on
the engine, etc.
NOTICE
■Do not use any fluid other than
washer fluid
Do not use soapy water or engine anti-
freeze instead of washer fluid.
Doing so may cause streaking on the
vehicle’s painted surfaces, as well as
damaging the pump leading to problems
of the washer fluid not spraying.
■Diluting washer fluid
Dilute washer fluid with water as neces-
sary.
Refer to the freezing temperatures listed
on the label of the washer fluid bottle.
