Lexus Safety System +
The Lexus Safety Sy stem + consists
of the following drive assist systems
and contributes to a safe and com-
fortable driving experience:
Driving assist system
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 con-
ditions.
As there is a limit to the degree of recog-
nition accuracy and control performance
that this system can provide, do not
overly rely on this system. The driver is
always responsible for paying attention
to the vehicle’s surro undings and driving
safely.
Sensors
WARNING
■To avoid malfunction of the radar sen-
sor
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 the radar
sensor cover clean at all times.
Radar sensor
Radar sensor cover
If the front of the rada r sensor or the front
or back of the radar sensor cover is dirty
or covered with water droplets, snow,
etc., clean it.
Clean the radar sensor and radar sensor
cover with a soft cloth to avoid damaging
them.

1824-5. Using the driving support systems
system determines that the possibility of a
frontal collision with a vehicle or pedestrian
is high.
Each function is operational at the following
speeds:
●Pre-collision warning:
• Vehicle speed is be tween approximately
7 and 110 mph (10 and 180 km/h). (For
detecting a pedestrian, vehicle speed is
between approximately 7 and 50 mph
[10 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or pedestrian ahead is
approximately 7 mph (10 km/h) or more.
●Pre-collision brake assist:
• Vehicle speed is be tween approximately
20 and 110 mph (30 and 180 km/h). (For
detecting a pedestrian, vehicle speed is
between approximately 20 and 50 mph
[30 and 80 km/h].)
• The relative speed between your vehicle
and the vehicle or pedestrian ahead is
approximately 20 mph (30 km/h) or
more.
●Pre-collision braking:
• Vehicle speed is be tween approximately
7 and 110 mph (10 and 180 km/h). (For
detecting a pedestrian, vehicle speed is
between approximately 7 and 50 mph
[10 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or pedestrian ahead is
approximately 7 mph (10 km/h) or more.
The system may not operate in the following
situations:
●If a battery terminal has been discon-
nected and reconnected and then the
vehicle has not been driven for a certain
amount of time
●If the shift position is in R
●If VSC is disabled (only the pre-collision
warning function will be operational)
■Pedestrian detection function
The pre-collision system detects pedestri-
ans based on the size, profile, and motion of
a detected object. However, a pedestrian
may not be detected depending on the sur-
rounding brightness and the motion, pos-
ture, and angle of the detected object,
preventing the system from operating properly. (
P.184)
■Cancelation of the pre-collision braking
If either of the follo wing occur while the
pre-collision braking fu nction is operating,
it will be canceled:
●The accelerator pedal is depressed
strongly.
●The steering wheel is turned sharply or
abruptly.
■Conditions under which the system may
operate even if there is no possibility of a
collision
●In some situations su ch as the following,
the system may determine that there is a
possibility of a frontal collision and oper-
ate.
• When passing a vehicle or pedestrian
• When changing lanes while overtaking a
preceding vehicle
• When overtaking a preceding vehicle
that is changing lanes
• When overtaking a preceding vehicle that is making a left/right turn
• When passing a vehicle in an oncoming lane that is stopped to make a right/left
turn

1864-5. Using the driving support systems
■Lane departure alert function
When the system determines that the
vehicle might depart from its lane, a
warning is displayed on the multi-infor-
mation display, and either the warning
buzzer sounds to alert the driver.
When the warning buzzer sounds, check
the surrounding road situation and care- fully operate the steering wheel to move
the vehicle back to the center of the lane.
■Steering assist function
When the system determines that the
vehicle might depart from its lane, the
system provides assistance as neces-
sary by operating the steering wheel in
small amounts for a short period of
time to keep the vehicle in its lane.
If the system detects that the steering
wheel has not been operated for a fixed
amount of time or the steering wheel is not
being firmly gripped, a warning is dis-
played on the multi-information display
and the warning buzzer sounds.
LKA (Lane-Keeping Assist)
When driving on highways and
freeways with white or yellow lines,
this function alerts the driver when
the vehicle might depart from its
lane and provides assistance by
operating the steering wheel to
keep the vehicle in its lane. Further-
more, the system also provides
steering assistance when dynamic
radar cruise control with full-speed
range is operating to keep the vehi-
cle in its lane.
The LKA system recognizes visible
white or yellow lines with the front
camera on the upper portion of the
front windshield.

tem

Driving■Vehicle sway warning function
When the vehicle is swaying or
appears as if it may depart from its lane
multiple times, the warning buzzer
sounds and a message is displayed on
the multi-information display to alert
the driver.
■Lane centering function
This function is linked with radar cruise
control and provides the required
assistance by operating the steering
wheel to keep the vehicle in its current
lane.
When radar cruise control is not operat-
ing, the lane centering function does not
operate.
If the system detects that the steering
wheel has not been operated for a fixed
amount of time or the steering wheel is not
being firmly gripped, a warning is dis-
played on the multi-information display
and the warning buzzer sounds.
