Sensor detection information ●
Certain vehicle conditions and the su rrounding environment may affect the
ability of a sensor to correctly detect an obstacle. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on a sensor.
• A sensor is frozen.
• A sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines,
air brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensor s in the vicinity.
• A sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or radio antenna.
• Towing eyelets are installed.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or right-angled curb.
• In harsh sunlight or intense cold weather.
• A non-genuine Lexus suspension (low ered suspension, etc.) is installed.
In addition to the examples above, there are instances in which, because of their
shapes, signs and other objects may be judg ed by a sensor to be closer than they
are. ●
The shape of the obstacle may prevent a sensor from detecting it. Pay particular
attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materi als that absorb sound waves
• Sharply-angled objects
•Low obstacles
• Tall obstacles with upper sections projec ting outwards in the direction of your
vehicle

2782-4. Using other driving systems
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)

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.

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.●
