Detection range of the sensorsApproximately 2.0 ft. (60 cm)
Approximately 2.8 ft. (85 cm)
Approximately 5.9 ft. (180 cm)
The diagram shows the detection
range of the sensors. Note that
the sensors cannot detect obsta-
cles that are extremely close to
the vehicle.
The range of the sensors may
change depending on the shape
of the object etc.

■Sensor detection information
●Certain vehicle conditions and the surrounding 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.
• The sensor is frozen.
• The 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 sensors 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.
• 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
In addition to the examples above, there are instances in which, because of
their shapes, 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 vehicle

CAUTION
■Caution when using the Intu itive parking assist-sensor
Observe the following precautions.
Failure 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).

Rear view monitor system
: If equipped
The rear view monitor system assists the driver by displaying an
image of the area behind the vehicle while reversing. The image is
displayed in reverse on the screen. This reversed image is a similar
image to the one on the inside rear view mirror.
The rear view image is dis-
played when the shift lever is
in the R position.
If the shift lever is shifted out of
R, the screen returns to the
previous one.

■Rear view monitor system camera
■ Smear effect
In the following cases, it may be difficult
to see the images on the screen, even
when the system is functioning correctly.
• The vehicle is in a dark area, such as
at night.
• The temperature near the lens is extremely high or low.
• Water droplets are on the camera lens or humidity is high, such as when it
rains.
• Foreign matter, such as snow and mud, adheres to the camera lens.
• The sun or headlights are shining directly into the camera lens.
• When the camera is used under fluo- rescent lights, sodium lights, mercury
lights etc., the lights and the illumi-
nated areas may appear to flicker.
• If the lens is scratched.
If a bright light, such as sunlight reflected
off the vehicle body, is picked up by the
camera, a smear effect
* characteristic to
the camera may occur.
*: Smear effect – A phenomenon that occurs when a bright light is picked up
by the camera; when transmitted by
the camera, the light source appears to
have a vertical streak above and below
it.
