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.

some time) and the normal operating conditions are detected, the message will disap-
pear 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 bright 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-
SituationActions
When the area around a camera is covered
with dirt, moisture (fogged up, covered with
condensation, ice, etc.), or other foreign
matter
Using the wiper and A/C function, remove
the dirt and other attached matter. (P.271)
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 sunlight
reflected from the surface of the sunshade
may cause the temperature of the front cam-
era 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.

QObject detection function
The system detects objects based on their
size, profile, motion, etc. However, an
object may not be detected depending on
the surrounding brightness and the motion,
posture, and angle of the detected object,
preventing the system from operating
properly. ( P.190) The illustration shows
an image of detectable objects.
QConditions under which the system may
operate even if there is no possibility of a
collision
OIn some situations such as the following,
the system may determine that there is a
possibility of a frontal collision and oper-
ate.
• When passing a detectable object, etc. • When changing lanes while overtaking a
detectable object, etc.
• When approaching a detectable object
in an adjacent lane or on the roadside,
such as when changing the course of
travel or driving on a winding road
• When rapidly closing on a detectable object, etc.
• When approaching objects on the road- side, such as detectable objects, guard-
rails, utility poles, trees, or walls
