■To avoid malfunction of the camera sensor
Observe the following precautions.
Otherwise, the camera sensor may not operate properly, possibly leading to an acci-
dent resulting in death or serious injury.
●Keep the windshield clean at all times.
• If the windshield is dirty or covered with an oily film, water droplets, snow, etc.,
clear the windshield.
• If a glass coating agent is applied to the windshield, it will still be necessary to use the windshield wipers to remove water drop lets from the area of the windshield in
front of the camera sensor.
• If the inner side of the windshield where th e camera sensor is installed is dirty, con-
tact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
●If the part of the windshield in front of the camera sensor is fogged up or covered with
condensation or ice, use the windshield defogger to remove the fog, condensation or
ice. ( →P. 3 7 2 )
●If water droplets cannot be properly remove d from the area of the windshield in front
of the camera sensor by the windshield wipers, replace the wiper insert or wiper
blade.
If the wiper inserts or wiper blades need to be replaced, contact any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.
●Do not attach window tinting to the windshield.
●Replace the windshield if it is damaged or cracked.
If the windshield needs to be replaced, contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
●Do not get the camera sensor wet.
●Do not allow bright lights to shine into the camera sensor.
●Do not dirty or damage the camera sensor.
When cleaning the inside of the windshield, do not allow glass cleaner to contact the
lens. Also, do not touch the lens.
If the lens is dirty or damaged, contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
●Do not install an antenna or attach stickers
(including transparent stickers) or other items

■Operational conditions
Availability of the pedestrian detection function and pre-crash braking function depend
on the region in which the vehicle was sold.
Read the following for details:
XRegion A
(The pedestrian detection function and pre-crash braking function are available)

frontal collision with a vehicle or pedestrian is high.
Each function is operational at the following speeds:
●Pre-crash warning:
• Vehicle speed is between approximately 10 and 180 km/h (7 and 110 mph). (For detecting a pedestrian, vehicle speed is between approximately 10 and 80 km/h [7
and 50 mph].)
• The relative speed between your vehicle and the vehicle or pedestrian ahead is approximately 10 km/h (7 mph) or more.
●Pre-crash brake assist:
• Vehicle speed is between approximately 30 and 180 km/h (19 and 110 mph). (Fordetecting a pedestrian, vehicle speed is between approximately 30 and 80 km/h
[19 and 50 mph].)

■Situations in which the system may not operate properly
●In some situations such as the following, a vehicle may not be detected by the radar
sensor and camera sensor, preventing the system from operating properly:
• If an oncoming vehicle is approaching your vehicle
• If a vehicle ahead is a motorcycle or bicycle
• When approaching the side or front of a vehicle
• If a preceding vehicle has a small rear end, such as an unloaded truck
• If a vehicle ahead is carrying a load which protrudes past its rear bumper
• If a vehicle ahead is irregularly shaped, such as a tractor or side car
• If the sun or other light is shining directly on a vehicle ahead
• If a vehicle cuts in front of your vehicle or emerges from beside a vehicle
• If a vehicle ahead makes an abrupt maneuver (such as sudden swerving, accelera-
tion or deceleration)
• When suddenly cutting behind a preceding vehicle
• When driving in inclement we ather such as heavy rain, fog, snow or a sandstorm
• When the vehicle is hit by water, snow, dust, etc. from a vehicle ahead
• When driving through steam or smoke
• When driving in a place where the surrounding brightness changes suddenly, such as at the entrance or exit of a tunnel
• When a very bright light, such as the sun or the headlights of oncoming traffic, shines directly into the camera sensor
• When the surrounding area is dim, such as at dawn or dusk, or while at night or in a
tunnel

■If the PCS warning light flashes and a warning message is displayed on the multi-infor-
mation display
The pre-crash safety system may be temporarily unavailable or there may be a malfunc-
tion in the system.
●In the following situations, the warning light will turn off, the message will disappear and
the system will become operational when normal operating conditions return:
• When the radar sensor or camera sensor or the area around either sensor is hot, such as in the sun
• When the radar sensor or camera sensor or the area around either sensor is cold,
such as in an extremely cold environment

• If the camera sensor is obstructed, such as when the hood is open or a sticker is
attached to the windshield near the camera sensor
●If the PCS warning light continues to flash or the warning message does not disappear,
the system may be malfunctioning. Have the vehicle inspected by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional immediately.
