■Sensor detection information
●The sensor’s detection areas are limited to the areas around the vehicle’s front corner
and rear bumpers.
●Certain vehicle conditions and the surround ing environment may affect the ability of
the sensor to correctly detect obstacles. Particular instances where this may occur are
listed below.
• There is dirt, snow or ice on the sensor . (Wiping the sensors will resolve this prob-
lem.)
• The sensor is frozen. (Thawing th e area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show an abnormal
display, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning co nsiderably 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 sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (low ered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there ar e instances in which, because of their shape,
signs and other objects may be judged by the sensor to be closer than they are.
●The shape of the obstacle may prevent the sensor from detecting it. Pay particular
attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
•Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your vehi-
cle
●The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance may shorten, or detect ion may be impossible.
• Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obst acle detection and display. Even at slow
speeds, there is a possibility that the obstacle will come within the sensor’s detection
areas before the display is shown and the warning beep sounds.
• Thin posts or objects lower than the sensor may not be detected when approached,
even if they have been detected once.
• It might be difficult to hear beeps due to the volume of the audio system or air flow noise of the air conditioning system.

■Certification
For vehicles sold in the U.S.A.
This device complies with Part 15 of the FC C Rules. Operation is subject to the following
two conditions; (1) This device may not caus e harmful interference, and (2) this device
must accept any interference received, incl uding interference that may cause undesired
operation.

Cet appareil ISM est conforme a la norme NMB-001 du Canada.
CAUTION
■When using the intuitive parking assist
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driven safely and possibly
cause an accident.
●Do not use the sensor at speeds in excess of 6 mph (10 km/h).
●The sensors’ detection areas and reaction times are limited. When moving forward or
reversing, check the areas surrounding the vehicle (especially the sides of the vehi-
cle) for safety, and drive slowly, using the brake to control the vehicle’s speed.
●Do not install accessories within the sensors’ detection areas.
NOTICE
■When using intuitive parking assist
In the following situations, the system may not function correctly due to a sensor mal-
function etc. Have the vehicle checked by your Lexus dealer.
●The intuitive parking assist operation display flashes, and a beep sounds when no
obstacles are detected.
●If the area around a sensor collides with so mething, or is subjected to strong impact.
●If the bumper or grille collides with something.
●If the display shows continuously without beeping, except when the buzzer mute
switch has been turned on.
●If a display error occurs, first check the sensor.
If the error occurs even when there is no ice, snow or mud on the sensor, it is likely that
the sensor is malfunctioning.
■Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in th e sensor malfunctioning.

The rear view image is displayed when
the shift position is in R and the engine
switch is in IGNITION ON mode.
The rear view monitor system will be
deactivated when the shift lever is in any
position other than R.
Rear view monitor system
: If equipped
The rear view monitor system assists the driver by displaying guide lines and
an image of the view behind the vehi cle while backing up, for example while
parking.
The screen illustrations used in this text are intended as examples, and may dif-
fer from the image that is actually displayed on the screen.

■Screen description
The rear view monitor system screen will be displayed if the shift lever is
shifted to R while the engine switch is in IGNITION ON mode. Vehicle width guide lines
The line indicates a guide path when the vehicle is being backed straight up.
The displayed width is wider than the actual vehicle width.
Vehicle center guide lines
These lines indicate the estimated vehicle center on the ground.
Distance guide line
The line shows points approximately 1.5 ft. (0.5 m) (red) from the center of the
edge of the bumper.
Distance guide line
The line shows distance behind the vehicle, a point approximately 3 ft. (1 m) (blue)
from the edge of the bumper.

■Area displayed on screen
The rear view monitor system dis-
plays an image of the view from the
bumper of the rear area of the vehi-
cle.
To adjust the image on the rear view
monitor system screen. (P. 2 7 2 )
• The area displayed on the screen
may vary according to vehicle orien-
tation conditions.
• Objects which are close to either corner of the bumper or under the
bumper cannot be seen on the
screen.
• The camera uses a special lens. The
distance of the image that appears
on the screen differs from the actual
distance.
• Items which are located higher than the camera may not be displayed by
the monitor.

●When any part of the vehicle sags
When any part of the vehicle sags
due to the number of passengers or
the distribution of the load, there is a
margin of error between the fixed
guide lines on the screen and the
actual distance/course on the road.
■When approaching three-dimensional objects
The distance guide lines are displayed according to flat surfaced objects (such
as the road). It is not possible to determine the position of three-dimensional
objects (such as vehicles) using the di stance guide lines. When approaching a
three-dimensional object that extends ou tward (such as the flatbed of a truck),
be careful of the following.
●Distance guidelines
Visually check the surroundings and
the area behind the vehicle. On the
screen, it appears that a truck is
parked at point . However, in real-
ity if you back up to point , you will
hit the truck. On the screen, it
appears that is closest and is
furthest away. However, in reality, the
distance to and is the same,
and is farther than and .
