●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 materi als that absorb sound waves
• Sharply-angled objects
•Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your vehicle
●The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection dis-
tance may shorten, or detection 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 se nsor may not be detected for collision
when approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of audio system or air flow noise of air conditioning system.

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 possi-
bly 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 for-
ward or reversing, check the areas surrounding the vehicle (especially the sides
of the vehicle) 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-sensor
In the following situations, the system may not function correctly due to a sensor
malfunction etc. Have the vehicl e checked by your Lexus dealer.
●The intuitive parking assist operation disp lay flashes, and a beep sounds when no
obstacles are detected.
●If the area around a sensor collides with something, or is subjected to strong
impact.
●If the bumper collides with something.
●If the display shows continuously without a beep.
●If a display error occurs, first check the sensor.
If the error occurs even if 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 wa ter or steam to the sensor area.
Doing so may result in the sensor malfunctioning.

Rear view monitor system
Rear view monitor system will acti-
vate when the shift lever is in R.
If you move the lever out of R, the rear
view monitor system will be deacti-
vated.
When the shift lever is shifted to the R
position and any mode button (such as
“MENU”) is pressed, the rear view
monitor system is canceled, and the
screen is switched to the mode of the
button that was pressed.
The rear view monitor system assist s the driver by displaying an image
of the view behind the vehicle and fixation guide lines while backing up,
for example while parking.
The screen illustrations used in this text are intended as examples, and
may differ from the image that is ac tually 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 extension guide line
The line indicates a guide path when th e vehicle is being backed straight up.
The displayed width is wider than the actual vehicle width.
Vehicle center guide line
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 vehi cle, a point approximately 3 ft. (1 m)
(blue) from the edge of the bumper.
Intuitive parking assist display (if equipped)
If an obstacle is detected while the In tuitive parking assist-sensor is on, a dis-
play is shown in the top right corner of the screen.

■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
vehicle.
To adjust the image on the rear
view monitor system screen.
(P. 316)
• The area displayed on the screen
may vary according to vehicle ori-
entation 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 dis-
played by the monitor.
• If your vehicle is equipped with a backlit license plat e, it may inter-
fere with the display.

■Rear view monitor system camera
The camera for the rear view
monitor system is located above
the license plate.
●Using the camera
If the camera lens becomes dirty, it cannot transmit a clear image. If
water droplets, snow or mud adhere to the lens, rinse with water and
wipe with a soft cloth. If the lens is extremely dirty, wash it with a mild
cleanser and rinse.
■Differences between the screen and the actual road
The distance guide lines and the vehicle width extension guide lines
may not actually be parallel with the dividing lines of the parking space,
even when they appear to be so. Be sure to check visually.
The distances between the vehicle width extension guide lines and the
left and right dividing lines of the parking space may not be equal, even
when they appear to be so. Be sure to check visually.
The distance guide lines give a dist ance guide for flat road surfaces. In
any of the following situations, th ere is a margin of error between the
fixation guide lines on the screen and the actual distance/course on the
road.

●When the ground behind the vehicle slopes up sharply
The distance guide lines will
appear to be closer to the
vehicle than the actual dis-
tance. Because of this, objects
will appear to be farther away
than they actually are. In the
same way, there will be a mar-
gin of error between the
guidelines and the actual dis-
tance/course on the road.
●When the ground behind the vehicle slopes down sharply
The distance guide lines will
appear to be further from the
vehicle than the actual dis-
tance. Because of this, objects
will appear to be closer than
they actually ar e. In the same
way, there will be a margin of
error between the guidelines
and the actual distance/course
on the road.

●When any part of the vehicle sags
When any part of the vehicle
sags due to the number of pas-
sengers or the distribution of
the load, there is a margin of
error between the fixation
guide lines on the screen and
the actual distance/course on
the road.
■When approaching three-dimensional objects
The distance guide lines are disp layed 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 distance guide
lines. When approaching a three-dime nsional object that extends out-
ward (such as the flatbed of a tru ck), be careful of the following.
●Distance guidelines
Visually check the surround-
ings and the area behind the
vehicle. On the screen, it
appears that a truck is parking
at point . However, in reality
if you back up to point , you
will hit the truck. On the
screen, it appears that is
closest and is farthest away.
However, in reality, the dis-
tance to and is the
same, and is farther than
and .

■Vehicle width extension guide lines
Visually check the surroundings and the area behind the vehicle. In the
case shown below, the truck appears to be outside of the vehicle width
extension guide lines and the vehicle does not look as if it hits the truck.
However, the rear body of the truck may actually cross over the vehicle
width extension guide lines. In reality if you back up as guided by the
vehicle width extension guide lines, the vehicle may hit the truck.
