shield wiper frequency
6 Decreases the intermittent wind-
shield wiper frequency
7 Washer/wiper dual opera-
tion
Pulling the lever operates the wipers and
washer.
The wipers will automatically operate a
couple of times afte r the washer squirts.
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 he
adlight cleaners will
operate every 5th time the lever is pulled.
■The windshield wiper and washer can be
operated when
The engine switch is in IGNITION ON
mode.
■Dripping prevention wiper sweep
After performing a washing and wiping
operation several times, the wipers operate
one more time after a short delay to prevent
dripping.
However, this final wiper operation will not
be performed while driving.
■Effects of vehicle speed on wiper opera-
tion (vehicles with rain-sensing wind-
shield wipers)
Vehicle speed affects the following even
when the wipers are not in AUTO mode.
●Intermittent wiper interval
●Wiper operation when the washer is
being used (delay until drip prevention
wiper sweep occurs)
With low speed windshield wiper opera-
tion selected, wipe r operation will be
switched from low sp eed to intermittent
wiper operation only when the vehicle is
stationary.
■Raindrop sensor (vehicles with
rain-sensing wind shield 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 bugs etc. are
present on the windshield.

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 -22°F
(-30°C) or lower, automatic operation
may not occur. In this case, operate the
wipers in any mode other than AUTO
mode.
■When the windshield wipers are in tem-
porary operation (vehicles with
rain-sensing windshield wipers)
AUTO mode cannot be activated even if
is pressed.
■If no windshield washer fluid sprays
Check that the washer nozzles are not
blocked if there is wash er fluid in the wind-
shield washer fluid reservoir.
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 leve r 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.

RC F Owner's Manual
●In the following situations, if the situation has changed (or the vehicle has been driven for
some time) and the normal operating conditio ns are detected, the message will disappear
and the system will become operational.
If the message does not disappear, contact your Lexus dealer.
• When the temperature around the radar sensor is outside of the operational range, such as when the vehicle is in the sun or in an extremely cold environment
• When the front camera cannot detect objects in front of the vehicle, such as when driving
in the dark, snow, or fog, or when brig ht lights are shining into the front camera
• Depending on the conditions in the vicinity of the vehicle, the radar may judge the sur- rounding environment can not be properly re cognized. In that case, “Pre-Collision Sys-
tem Unavailable” is displayed.
SituationActions
When the area around a sensor is covered
with dirt, moisture (f ogged up, covered with
condensation, ice, etc. ), or other foreign
matterTo clean the part of the windshield in front of
the front camera , use the windshield wipers
or the windshield defo gger of the air condi-
tioning system ( P.215).
When the temperature around the front
camera is outside of the operational range,
such as when the vehicle is in the sun or in an
extremely cold environment
If the front camera is hot, such as after the
vehicle had been parked in the sun, use the
air conditioning system to decrease the tem-
perature around the front camera.
If a sunshade was used when the vehicle
was parked, depending on its type, the sun-
light reflected from the surface of the sun-
shade may cause the temperature of the
front camera to become excessively high.
If the front camera is cold, such after the
vehicle is parked in an extremely cold envi-
ronment, use the air conditioning system to
increase the temperature around the front
camera.
The area in front of the front camera is
obstructed, such as when the hood is open
or a sticker is attached to the part of the
windshield in front of the front camera.
Close the hood, remove the sticker, etc. to
clear the obstruction.
When “Pre-Collision Sy stem Unavailable” is
displayedCheck whether there is attached materials
on the radar sensor and radar sensor cover,
and if there is, remove it.
