The sensor operation display flashes and the buzzer sounds even when no obsta-
cle is detected.
●
An area of the sensors is hit or subjected to a strong impact.

Pre-Collision System When the radar sensor detects the possib ility of a frontal collision, the pre-
collision system such as the brakes and seat belts are automatically
engaged to lessen impact as well as vehicle damage.
■ Pre-collision seat belts (front seat belts only) If the pre-collision sensor detects that a collision is unavoidable, the pre-
collision system will retract the seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or loses
control of the vehicle. (  P. 8 5 )
However, the system will not operate in the event of skidding when the
VSC system is disabled.
■ Pre-collision brake assist When there is a high possibility of a frontal collision, the system applies
greater braking force in relation to how strongly the brake pedal is
depressed. The system may not warn the driver using a warning light,
warning display and buzzer when the system detects and judges braking
operations.
■ Pre-collision braking When there is a high possibility of a frontal collision, the system warns the
driver using a warning light, warnin g display and buzzer. If the system
determines that a collision is unavoidable, the brakes are automatically
applied to reduce the collision speed. Pre-collision braking can be dis-
abled using the pre-collision braking off switch.

When driving Disabling pre-collision braking
Pre-collision braking disabled
Pre-collision braking enabled The pre-collision system warning
light turn on when pre-collision
braking is disabled.
Radar sensor
The radar sensor detects vehicles
or other obstacles on or near the
road ahead and determines
whether a collision is imminent
based on the posit ion, speed, and
heading of the obstacles.

2822-4. Using other driving systems
■
Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may also be
occasions when the sensor cannot detect pedestrians, animals, bicycles, motorcy-
cles, trees, or snowdrifts. ■
Situations in which the pre-collision system does not function properly
The system may not function effectively in situations such as the following: ●
On roads with sharp be nds or uneven surfaces●
If a vehicle suddenly moves in front of your vehicle, such as at an intersection●
If a vehicle suddenly cuts in front of your vehicle, such as when overtaking●
In inclement weather such as heav y rain, fog, snow or sand storms●
When your vehicle is skiddi ng with the VSC system off●
When an extreme change in vehicle height occurs●
When the axis of the radar is out of adjustment■
Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in the
sensors being unable to detect obstacles, the pre-collision system will be automati-
cally disabled. In this case, the system will not activate even if there is a collision pos-
sibility.■
When there is a malfunction in the system, or if the system is temporarily unus-
able
Warning lights and/or warning messages will turn on or flash. (  P. 744, 754)

When driving CAUTION■
When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary in any of the following situations: ●
When water or snow thrown up by the surrounding vehicles hinders the function-
ing of the sensor●
When your vehicle is pointing upwards (caused by a heavy load in the luggage
compartment etc.)●
Vehicles that cut in suddenly●
Vehicles with small rear ends (tra ilers with no load on board etc.)●
Motorcycles traveling in the same lane■
Handling the radar sensor
Observe the following to ensure the pre-collision system can function effectively: ●
Keep the sensor and front grille clean at all times.
Clean the sensor and front grille with a so ft cloth so you do not mark or damage
them.●
Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off po sition, the system may become inaccurate
or malfunction. If the sensor or surround ing area is subject to a strong impact,
always have the area inspected an d adjusted by your Lexus dealer.●
Do not disassemble the sensor.●
Do not attach accessories or stickers to the sensor, grille or surrounding area.●
Do not modify or paint the sensor and grille cover.

BSM (Blind Spot Monitor) 
 : If equippedThe Blind Spot Monitor is a system that assists the driver in making the
decision to change lanes.
The system uses radar sensors to detect vehicles that are traveling in an
adjacent lane in the area that is not reflected in the outside rear view mirror
(the blind spot), and advises the driver of the vehicles existence via the out-
side rear view mirror indicator.
BSM main switch Pressing the switch turns the system on or off.
Outside rear view mirror indicator When a vehicle is detected in the blind spot, the outside rear view mirror
indicator on that side illuminates. If the turn signal lever is operated when a
vehicle is in the blind spot, the outsid e rear view mirror indicator flashes.
BSM indicator
When the system is on, the indicator will come on.

The outside rear view mirror indicators visibility
When under strong sunlight, the outside rear view mirror indicator may be difficult
to see.■
When there is a malfunction in the system
If a system malfunction is detected due to any of the following reasons, warning
message is displayed: (  P. 7 5 4 )●
There is a malfunction with the sensors●
The sensors have become dirty●
The outside temperature is extremely high or low●
The sensor voltage has become abnormal■

When driving CAUTION■
Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
The Blind Spot Monitor is a supplementary system which alerts the driver that a
vehicle is present in the blind spot. Do not overly rely on the Blind Spot Monitor. The
system cannot judge if it is safe to change lanes, therefore over reliance could cause
an accident resulting in death or serious injury. According to conditions, the system
may not function correctly. Therefore the driver’s own visual confirmation of safety
is necessary.■
Handling the radar sensor
One Blind Spot Monitor is installed inside the left and right side of the vehicle rear
bumper respectively. Observe the followin g to ensure the Blind Spot Monitor can
function correctly.
●
Do not subject the sensor or surrounding area on the bumper to a strong impact.
If the sensor moves even slightly off position, the system may malfunction and
vehicles that enter the detection area ma y not be detected. If the sensor or sur-
rounding area is subject to a strong impact, always have the area inspected by
your Lexus dealer.●
Do not disassemble the sensor.
●
Do not attach accessories or stickers to the sensor or surrounding area on the
bumper.
●
Do not modify the sensor or surrounding area on the bumper.
●
Do not paint the sensor or surrounding area on the bumper. ●
Keep the sensor and its surrounding area
on the bumper clean at all times.
