The Lexus Safety System + consists of th e following drive assist systems and
contributes to a safe and comfo rtable driving experience:
WARNING
■Lexus Safety System +
The Lexus Safety System + is designed to operate under the assumption that the driver
will drive safely, and is designed to help reduce the impact to the occupants and the
vehicle in the case of a collision or assist the driver in normal driving conditions.
As there is a limit to the degree of reco gnition accuracy and control performance that
this system can provide, do not overly rely on this system. The driver is always responsi-
ble for paying attention to the vehicle’s surroundings and driving safely.

shield in front of the front camera.
• If the inner side of the wind shield where the front camera is installed is dirty, con-
tact your Lexus dealer.
●If the part of the windshield in front of the front camera is fogged up or covered with
condensation or ice, use the windshield defogger to remove the fog, condensation or
ice. ( P. 380)
●If water droplets cannot be properly removed from the area of the windshield in front
of the front camera by the wi ndshield wipers, replace the wiper insert or wiper blade.

■If a warning message is displayed
on the multi-information display
A system may be temporarily unavailable or there may be a malfunction in the system
●In the following situations, perform the acti ons specified in the table. When the normal
operating conditions are detected, the message will disappear and the system will
become operational.
If the message does not disappear, contact your Lexus dealer.
●In the following situations, if the situatio n has changed (or the vehicle has been driven
for some time) and the normal operating conditions are detected, the message will dis-
appear and the system w ill become operational.
If the message does not disappear, contact your Lexus dealer.
• When the temperature around the radar sens or 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 cam-
era
SituationActions
When the area around a sensor is
covered with dirt, moisture (fogged
up, covered with condensation, ice,
etc.), or othe r foreign matterTo clean the part of the windshield in front of
the front camera, use the windshield wipers or
the windshield defogger of the air conditioning
system (P. 380).
When the temperature around the
front camera is outside of the opera-
tional range, such as when the vehi-
cle is in the sun or in an extremely
cold environment
If the front camera is hot, such as after the vehi-
cle had been parked in the sun, use the air con-
ditioning system to de crease the temperature
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 environment, use
the air conditioning system to increase the tem-
perature around the front camera.
The area in front of the front camera
is obstructed, su ch 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.

PCS (Pre-Collision System)
◆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.
The pre-collision system uses a radar sensor and camera sensor to detect
vehicles and pedestrians in front of yo ur vehicle. When the system determines
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 the possibility of a fr ontal collision with a vehicle or pedes-
trian is extremely high, the brakes are automatically applied to help avoid the
collision or help reduce the impact of the collision.
The pre-collision system can be disabled/enabled and the warning timing can
be changed. ( P. 238)
