■The Intuitive parking assist system can be operated when
●Front corner sensors:
• The engine switch is in the ON position.
• The shift lever is in R.
• The shift lever is not in P or R and vehicle speed is approximate 6 mph
(10 km/h) or less.
● Back and rear corner sensors:
• The engine switch is in the ON position.
• The shift lever is in R
■ Sensor detection information
●Certain vehicle conditions and the surrounding 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 intuitive 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.
• The area directly under the bumpers is not detected. Objects lower than the sensors or thin stakes etc. may be detected ini-
tially, but as they draw closer, they may cease to be detected.
• A towing hitch is mounted to the vehicle.
• A non-genuine Toyota suspension (lowered suspension etc.) is installed.
• When attaching a two-way radio antenna.
• When a towing eyelet is mounted on your vehicle.
• When the bumper is damaged.

232 2-4. Using other driving systems
In addition to the examples above, there are instances in which, because of
their shapes, signs and other objects may be judged 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 materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction
of your vehicle
• A person near the vehicle (depending on the type of clothes worn)
• When the bumper is damaged.
■ Certification (Canada only)
This ISM device complies with Canadian ICES-001.
■ If the indicator is continuously on
Have the vehicle inspected by your Toyota dealer.
■ If the indicator remains blinking but do not sound the buzzer
Clean the sensors with soft cloth.
CAUTION
■Caution when using the intuitive parking assist
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).
● When moving forward or reversing, always check your surroundings for
safety and drive carefully.
● Do not attach any accessories within the sensor range.

■Displayed area
■ Rear view monitor guide lines
●Guide lines are displayed on the monitor.
Vehicle width extension guide lines (blue)
These lines indicate the estimated vehicle width extension.
Distance guide line (blue)
This line indicates a position on the ground about 3 ft. (1 m) behind on the
ground of the rear bumper of your vehicle.
Distance guide line (red)
This line indicates a position on the ground about 1.5 ft. (0.5 m) behind on
the ground of the rear bumper of your vehicle.
Vehicle center guide lines (blue)
These lines indicate the estimated vehicle center on the ground.
The area covered by the camera is lim-
ited. Objects that are close to either
corner of the bumper or under the
bumper cannot be seen on the screen.
The area displayed on the screen may

■Driving precautions
When the grade behind the vehicle
slopes up sharply, objects appear to be
farther away than they actually are.
When the grade behind the vehicle
slopes down sharply, objects appear to
be closer than they actually are.

238 2-4. Using other driving systems
The distance that appears on the screen
between three-dimensional objects (such
as vehicles) and flat surfaces (such as
the road) and the actual distance differ as
follows.
In reality, C = A < B (C and A are equally
far away; B is farther than C and A). How-
ever, on the screen, the situation appears
to be A < B < C.
On the screen, it appears that a truck is
parking about 1.5 ft. (0.5 m) away. How-
ever, in reality if you back up to point A,
you will hit the truck.

■Rear view monitor system camera
■ Smear effect
The rear view monitor system camera is
located on the tailgate as shown in the
illustration.
In the following cases, it may become dif-
ficult to see the images on the screen,
even when the system is functioning cor-
rectly.
●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 or
mud, adheres to the camera lens.
● The sun or headlights are shining
directly into the camera lens.
● A bright object such as a white wall
is reflected in the mirror surface
over the monitor.
● When the camera has scratches or
dirt on it.
If a bright light, such as sunlight
reflected off the vehicle body, is picked
up by the camera, a smear effect* char-
acteristic 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.

240 2-4. Using other driving systems
■Flicker effect
When the camera is used under fluorescent lights, sodium lights, mercury
lights etc., the lights and the illuminated areas may appear to flicker.
CAUTION
■When using the rear view monitor system
Observe the following precautions to avoid an accident that could result in
death or serious injuries
● Never depend solely on the rear view monitor system when reversing.
● Always check visually and with the mirrors to confirm your intended path is
clear.
● Always check the vehicle surroundi ng area, because the guide lines are
estimates of distance and location.
● The guide lines are assistant lines and do not change even if the steering
wheel is turned.
● Depicted distances between objects and flat surfaces differ from actual
distances.
● Do not use the system if the tailgate open.
■ Conditions which may affect the rear view monitor system
● If the back of the vehicle has been hit, the camera’s position and mounting
angle may have changed. Have the vehicle inspected by your Toyota
dealer.
● Rapid temperature changes, such as when hot water is poured on the
vehicle in cold weather, may cause the system to function abnormally.
● If the camera lens is dirty, it cannot transmit a clear image. Rinse with
water and wipe with a soft cloth. If extremely dirty, wash with a mild
cleanser and rinse.
● The displayed image may be darker and moving images may be slightly
distorted when the system is cold.
■ Caution while driving in reverse
Do not change modes while the vehicle is moving.
