Safe Exit Assist*
The safe exit assist is a sys-
tem that uses rear side
radar sensors installed on
the inner side of the rear
bumper to help occupants
judge if an approaching
vehicle or bicycle may col-
lide with a door when exit-
ing, to help reduce the
possibility of a collision.
WARNING
■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 safe exit assist is a supple-
mentary system that, when the
vehicle is stopped, informs
occupants of th e existence of
approaching vehicles and bicy-
cles. As this system alone can-
not be used to judge safety,
over-reliance on this system
may lead to an accident result-
ing in death or serious injury.
In certain situations, this system
may not function to its fullest
extent. Therefore it is necessary
for the occupants to visually
check for safety directly and using
the mirrors.

■Cautions regarding the use of
the system
There is a limit to the degree of
recognition accuracy and control
performance that this system can
provide, do not overly rely on this
system. The driver is always
responsible for paying attention to
the vehicle’s surroundings and
driving safely.
■To ensure the system can
operate properly
Make sure to observe the follow-
ing precautions. The system may
not operate properly and may
lead to an unexpected accident.
When these precautions cannot
be observed, turn the system off.
●Do not damage the sensors,
and always keep them clean.
●Do not attach a st icker or install
an electronic component, such
as a backlit license plate (espe-
cially fluorescent type), fog
lights, fender pole or wireless
antenna near a radar sensor.
●Do not subject the surrounding
area of the sensor to a strong
impact. If subjected to an
impact, have the vehicle
inspected by your Toyota
dealer. If the front or rear
bumper needs to be
removed/installed or replaced,
contact your Toyota dealer.
●Do not modify, disassemble or
paint the sensors.
●Do not attach a license plate
cover.

3665-5. Using the driving support systems
■Objects which the system may
not properly detect
The shape of the object may pre-
vent the sensor from detecting it.
Pay particular attention to the fol-
lowing objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials
that absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections
projecting outwards in the direc-
tion of your vehicle
People may not be detected if they
are wearing certain types of cloth-
ing.
■Situations in which the system
may not operate properly
Certain vehicle conditions and the
surrounding environment may affect
the ability of a sensor to correctly
detect objects. Particular instances
where this may occur are listed
below.
●There is dirt, snow, water drops or
ice on a sensor. (Cleaning the
sensors will resolve this problem.)
●A sensor is frozen. (Thawing the
area will resolve this problem.)
In especially cold weather, if a
sensor is frozen the sensor dis-
play may be displayed abnor-
mally, or objects, such as a wall,
may not be detected.
●When a sensor or the area around
a sensor is extremely hot or cold.
●On an extremely bumpy road, on
an incline, on gravel, or on grass.
●When vehicle horns, vehicle
detectors, motorcycle engines, air
brakes of large vehicles, the clear-
ance sonar of other vehicles or
other devices which produce ultra-
sonic waves are near the vehicle.
●A sensor is coated with a sheet of
spray or heavy rain.
●If objects draw too close to the
sensor.
●When a pedestrian is wearing
clothing that does not reflect ultra-
sonic waves (ex. skirts with gath-
ers or frills).
●When objects that are not perpen-
dicular to the ground, not perpen-
dicular to the vehicle traveling
direction, uneven, or waving are in
the detection range.
●When strong winds are blowing.
●When driving in inclement weather
such as fog, snow or a sandstorm.
●When an object that cannot be
detected is between the vehicle
and a detected object.
●If an object such as a vehicle,
motorcycle, bicycle or pedestrian
cuts in front of the vehicle or runs
out from the side of the vehicle.
●If the orientation of a sensor has
been changed due to a collision or
other impact.
●When equipment such as a towing
eyelet, transport hook, bumper
protector, bumper trim, bicycle
carrier or snow-removal device
(snow plow) is installed near the
sensor.
●If the front of the vehicle is raised
or lowered due to the carried load.
●If the vehicle cannot be driven in a
stable manner, such as when the
vehicle has been in an accident or
is malfunctioning.
●When tire chains, a compact
spare tire or an emergency tire
puncture repair kit are used.
