Toyota Corolla Cross: Sensors used by Toyota
Safety Sense 3.0
Various sensors are used to
obtain the necessary information
for system operation.
■ Sensors which detect the
surrounding conditions
- Front radar sensor
- Front camera
WARNING
■To prevent malfunction of the
radar sensors
Observe the following precautions.
Failure to do so may lead to
a radar sensor not operating properly,
possibly leading to an accident
resulting in death or serious
injury.
- Keep the radar sensors and
radar sensor covers clean at all
times.
Clean the front of a radar sensor
or the front or back of a radar sensor
cover if it is dirty or covered
with water droplets, snow, etc.
When cleaning the radar sensor
and radar sensor cover, use a soft
cloth to remove dirt so as to not
damage them.
- Radar sensor
- Radar sensor cover
- Do not attach accessories,
stickers (including transparent
stickers), aluminum tape, etc. to
a radar sensor or radar sensor
cover and their surrounding
area.
- Do not subject a radar sensor or
its surrounding area to impact.
If a radar sensor, the front grille,
or front bumper has been subjected
to a impact, have the
vehicle inspected by your Toyota
dealer.
- Do not disassemble the radar
sensors.
- Do not modify or paint the radar
sensors or radar sensor cover,
or replace them with anything
other than Toyota genuine parts.
- In the following situations, recalibration
of the radar sensors will
be necessary. For details, contact
your Toyota dealer.
- When a radar sensor is
removed and installed, or
replaced
- When the front bumper or the
front grille has been replaced
■To prevent malfunction of the
front camera
Observe the following precautions.
Failure to do so may lead to the
front camera not operating properly,
possibly leading to an accident
resulting in death or serious
injury.
- Always keep the windshield
clean.
- If the windshield is dirty or covered
with an oily film, water
droplets, snow, etc., clean the
windshield.
- Even if a glass coating agent is
applied to the windshield, it will
still be necessary to use the
windshield wipers to remove
water droplets, etc. from the
area of the windshield in front of
the front camera.
- If the inner side of the windshield
where the front camera is
installed is dirty, contact your
Toyota dealer.
- Do not attach stickers (including
transparent stickers) or other
items to the area of the windshield
in front of the front camera
(shaded area in the
illustration).
- Approximately 1.6 in. (4 cm)
- Approximately 1.6 in. (4 cm)
- If the part of the windshield in
front of the front camera is
fogged up or covered with condensation
or ice, use the windshield
defogger to remove the
fog, condensation, or ice.
- If water droplets cannot be
properly removed from the area
of the windshield in front of the
front camera by the windshield
wipers, replace the wiper insert
or wiper blade.
- Do not attach window tint to the
windshield.
- Replace the windshield if it is
damaged or cracked.
If the windshield has been
replaced, recalibration of the
front camera will be necessary.
For details, contact your Toyota
dealer.
- Do not allow liquids to contact
the front camera.
- Do not allow bright lights to
shine into the front camera.
- Do not damage the lens of the
front camera or allow it to
become dirty.
When cleaning the inside of the
windshield, do not allow glass
cleaner to contact the lens of
the front camera. Do not touch
the lens of the front camera.
If the lens of the front camera is
dirty or damaged, contact your
Toyota dealer.
- Do not subject the front camera
to a strong impact.
- Do not change the position or
orientation of the front camera
or remove it.
- Do not disassemble the front
camera.
- Do not modify any parts around
the front camera, such as the
inside rear view mirror or ceiling.
- Do not attach accessories
which may obstruct the front
camera to the hood, front grille,
or front bumper. For details,
contact your Toyota dealer.
- If a surfboard or other long
object is to be mounted on the
roof, make sure that it will not
obstruct the front camera.
- Do not modify or change the
headlights and other lights.
■Front camera installation area
on the windshield
If the system determines that the
windshield may be fogged up, it
will automatically operate the
heater to defog the part of the
windshield around the front camera.
When cleaning, etc., be careful
not to touch the area around
the front camera until the windshield
has cooled sufficiently, as
touching it may cause burns.
■Situations in which the sensors
may not operate properly
- When the height or inclination of
the vehicle has been changed due
to modifications
- When the windshield is dirty,
fogged up, cracked or damaged
- When the ambient temperature is
high or low
