To avoid malfunction of the radar sensor
Observe the following precautions.
Otherwise, the radar sensor may not operate properly, possibly leading to an accident
resulting in death or serious injury. ●
Keep the radar sensor and front gr ille emblem clean at all times.
●
Do not attach accessories, stickers (inclu ding transparent stickers) or other items to
the radar sensor, front grille emblem or surrounding area. ●
Do not subject the radar sensor or su rrounding area to a strong impact.
If the radar sensor, front grille, or front bumper has been subjected to a strong impact,
have the vehicle inspected by your Lexus dealer. ●
Do not disassemble the radar sensor. ●
Do not modify or paint the radar sensor, front grille emblem or surrounding area. ●
If the radar sensor, front grille, or front bumper needs to be removed and installed, or
replaced, contact your Lexus dealer. ●
The radar sensor complies with relevant radio wave regulations, as shown by the label
attached to the sensor. Do not remove the label. Additionally, disassembly or modifi-
cation of the radar sensor may be prohibited by law. Radar sensor
Front grille emblem
If the front of the radar sensor or the front or
back of the front grille emblem is dirty or
covered with water droplets, snow, etc., clean
it.
Clean the radar sensor and front grille
emblem with a soft cloth so you do not mark
or damage them. 1

To avoid malfunction of the camera sensor
Observe the following precautions.
Otherwise, the camera sensor may not operat e 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 your Lexus dealer.
●
If the part of the windshield in front of th e camera sensor is fogged up or covered with
condensation or ice, use the windshield defogger to remove the fog, condensation or
ice. (  P. 500)●
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.
• To replace the wiper insert:  P. 6 0 1
• If the wiper blades need to be replaced, contact your Lexus dealer. ●
Do not attach window tinting to the windshield. ●
Replace the windshield if it is damaged or cracked.
If the windshield needs to be re placed, contact your Lexus dealer.●
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 damage d, contact your Lexus dealer.●
Do not install an antenna or attach stickers
(including transparent stickers) or other items
to the area of the windshield in front of the
camera sensor (shaded area in the illustra-
tion).

Do not subject the camera sensor to a strong impact. ●
Do not change the installation position or di rection of the camera sensor or remove it.●
Do not disassemble the camera sensor. ●
Do not install an electronic de vice or device that emits strong electric waves near the
camera sensor. ●
Do not modify any components of the vehicle around the camera sensor (inside rear
view mirror, sun visors, etc.) or ceiling. ●
Do not attach any accessories that may obst ruct the camera sensor to the hood, front
grille or front bumper. Contact your Lexus dealer for details. ●
If a surfboard or other long object is to be mounted on the roof, make sure that it will
not obstruct the camera sensor. ●
Do not modify the headlights or other lights.

RX350_U_OM48E90UPCS (Pre-Collision System) 
 : If equippedThe pre-collision system uses a radar sensor and camera sensor to detect
vehicles and pedestrians
* 1
in front of your vehicle. When the system deter-
mines that the possibility of a frontal collision with a vehicle or pedestrian is
high, a warning operates to urge the driver to take evasive action and the
potential brake pressure is increased to help the driver avoid the collision. If
the system determines that th e possibility of a frontal collision with a vehicle or
pedestrian is extremely high, the brakes are automatically applied
* 2
to help
avoid the collision or help reduce the impact to the vehicle occupants and the
vehicle in the collision.
The pre-collision system can be disabl ed/enabled and the warning timing can
be changed. (  P. 2 74 )
* 1
: Depending on the region in which the vehicle was sold, the pedestrian detection
function may not be available. Contact your Lexus dealer for details.
* 2
: Depending on the region in which the ve hicle was sold, the pre-collision braking
function (automatic braking function) may not be available. Contact your Lexus
dealer for details.

RX350_U_OM48E90U ◆ Pre-collision warning
When the system determines that
the possibility of a frontal collision is
high, a buzzer will sound and a warn-
ing message will be displayed on the
multi-information display to urge the
driver to take evasive action.
◆ Pre-collision brake assist
When the system determines that the po ssibility of a frontal collision is high,
the system applies greater braking force in relation to how strongly the brake
pedal is depressed.
◆ Pre-collision braking
* 3
When the system determines that the po ssibility of a frontal collision is high,
the system warns the driver. If the system determines that the possibility of a
collision is extremely high, the brakes are automatically applied to help avoid
the collision or reduce the collision speed.
* 3
: Depending on the region in which the vehi cle was sold, the pre-collision braking func-
tion may not be available.
◆ Suspension control (if equipped)
When the system determines that the po ssibility of a frontal collision is high,
the Adaptive Variable Suspension System (  P. 375) will control the damping
force of the shock absorbers.

Limitations of the pre-collision system ●
The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
Do not use the pre-collision system instea d of normal braking operations under any
circumstances. This system will not preven t collisions or lessen collision damage or
injury in every situation. Do not overly rely on this system. Failure to do so may lead to
an accident, resulting in death or serious injury.●
Although this system is design ed to help avoid and reduce the impact of a collision, its
effectiveness may change according to various conditions, therefore the system may
not always be able to achieve the same level of performance.
Read the following conditions carefully. Do not overly rely on this system and always
drive carefully.
• Conditions under which the system may operat e even if there is no possibility of a
collision:  P. 2 7 7
• Conditions under which the system may not operate properly:  P. 2 8 0●
Do not attempt to test the operation of the pre-collision system yourself, as the system
may not operate properly, poss ibly leading to an accident.■
Pre-collision braking
* 3
●
The pre-collision braking function may not operate if certain operations are per-
formed by the driver. If the accelerator peda l is being depressed strongly or the steer-
ing wheel is being turned, the system may de termine that the driver is taking evasive
action and possibly prevent the pre-colli sion braking function from operating.●
In some situations, while the pre-collision braking function is op erating, operation of
the function may be canceled if the accele rator pedal is depressed strongly or the
steering wheel is turned and the system determines that the driver is taking evasive
action. ●
A large amount of braking force is applied while the pre-collision braking function is
operating. Additionally, as the vehicle may creep if it has been stopped by the pre-
collision braking function, the driver should depress the brake pedal as necessary. ●
If the brake pedal is being depressed, the system may determine that the driver is tak-
ing evasive action and possibly delay the op eration timing of the pre-collision braking
function.
* 3
: Depending on the region in which the ve hicle was sold, the pre-collision braking
function may not be available.
