WARNING
■Toyota Safety Sense
The Toyota Safety Sense is designed
to operate under the assumption that the driver will drive safely, and is designed to help reduce the impact to
the occupants and the vehicle in the case of a collision or assist the driver in normal driving conditions.
As there is a limit to the degree of rec- ognition accuracy and control perfor-mance 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.

WARNING
■To avoid malfunction of the radar sensor
Observe the following precautions. Otherwise, the radar sensor may not operate properly, possibly leading to
an accident resulting in death or seri- ous injury.
●Keep the radar sensor and the radar sensor cover clean at all times.
Radar sensor
Radar sensor cover
If the front of the radar sensor or the
front or back of the radar sensor
cover is dirty or covered with water
droplets, snow, etc., clean it.
Clean the radar sensor and radar
sensor cover with a soft cloth to avoid
damaging them.
●Do not attach accessories, stickers (including transparent stickers) or
other items to the radar sensor, radar sensor cover or surrounding area.
●Do not subject the radar sensor or its surrounding area to a strong
impact. If the radar sensor, front grille, or front bumper has been subjected to
a strong impact, have the vehicle inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
●Do not disassemble the radar sen- sor.
●Do not modify or paint the radar sensor or radar sensor cover.
●In the following cases, the radar sensor must be recalibrated. Con-tact any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer for details.
• When the radar sensor or front grille are removed and installed, or replaced
• When the front bumper is replaced
■To avoid malfunction of the front camera
Observe the following precautions.
Otherwise, the front camera may not operate properly, possibly leading to an accident resulting in death or seri-
ous injury.
●Keep the windshield clean at all
times.
• If the windshield is dirty or covered
with an oily film, water droplets, snow, etc., clean the windshield.
• If a glass coating agent is applied to the windshield, it will still be neces-sary 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 any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.

■If a warning message is displayed on the multi-information display
A system may be temporarily unavailable or there may be a malfu nction in the sys-
tem.
●In the following situations, perform the actions specified in t he table. When the nor-
mal operating conditions are detected, the message will disappe ar and the system will become operational.
If the message does not disappear, contact any authorized Toyot a retailer or Toyota
authorized repairer, or any reliable repairer.
●In the following situations, if the situation has changed (or t he vehicle has been
driven for some time) and the normal operating conditions are d etected, the mes- sage will disappear and the system will become operational.
SituationActions
When the area around a camera is cov-
ered with dirt, moisture (fogged up, cov-
ered with condensation, ice, etc.), or
other foreign matter
Using the wiper and A/C function,
remove the dirt and other attached mat-
ter. ( P.344)
When the temperature around the front
camera is outside of the operational
range, such as when the vehicle is in the
sun or in an extremely cold environment
If the front camera is hot, such as after
the vehicle had been parked in the sun,
use the air conditioning system to
decrease the temperature around the
front camera.
If a sunshade was used when the vehicle
was parked, depending on its type, the
sunlight reflected from the surface of the
sunshade may cause the temperature of
the front camera to become excessively
high.
If the front camera is cold, such after the
vehicle is parked in an extremely cold
environment, use the air conditioning
system to increase the temperature
around the front camera.
The area in front of the front camera is
obstructed, such as when the hood is
open or a sticker is attached to the part of
the windshield in front of the front cam-
era.
Close the hood, remove the sticker, etc.,
to clear the obstruction.
When “Pre-Collision System Radar In
Self Calibration Unavailable See
Owner’s Manual” is displayed.
Check whether there is attached materi-
als on the radar sensor and radar sensor
cover, and if there is, remove it.

If the message does not disappear, contact any authorized Toyot a retailer or Toyota
authorized repairer, or any reliable repairer.
• When the temperature around the radar sensor is outside of the operational range,
such as when the vehicle is in the sun or in an extremely cold environment • When the front camera cannot detect objects in front of the ve hicle, such as when driving in the dark, snow, or fog, or when bright lights are sh ining into the front
camera • Depending on the conditions in the vicinity of the vehicle, th e radar may judge the surrounding environment can not be properly recognized. In that case, “Pre-Colli-
sion System Unavailable See Owner’s Manual” is displayed.

*: If equipped
The system can detect the following (The detectable objects differs
depending on the function.):
The countries and areas for each region listed in the table are current as of
July 2022. However, depending on when the vehicle was sold, the coun-
tries and areas of each region may be different. Contact any au thorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer for
details.
PCS (Pre-Collision System)*
The pre-collision system uses a rad ar sensor and front camera to
detect objects ( P.231) in front of the vehicle. When the system
determines that the possibility of a frontal collision with an object is
high, a warning operates to urge the driver to take evasive act ion
and the potential brake pressure is increased to help the drive r
avoid the collision. If the syste m determines that the possibility of a
frontal collision with an object is extremely high, the brakes are
automatically applied to help avoid the collision or help reduc e the
impact of the collision.
The pre-collision system can be disabled/enabled and the warnin g timing
can be changed. ( P.235)

■Enabling/disabling the pre-col-
lision system
The pre-collision system can be
enabled/disabled on ( P.494)
of the multi-information display.
The system is automatically enabled
each time the power switch is turned to
ON.
If the system is disabled, the PCS
warning light will turn on and a
message will be displayed on the
multi-information display.
“Pre-Collision System OFF”
■Changing the pre-collision
warning timing
The pre-collision warning timing
can be changed on ( P.494) of
the multi-information display.
The warning timing setting is retained
when the power switch is turned off.
However, if the pre-collision system is
disabled and re-enabled, the operation
timing will return to the default setting
(middle).
For region A: If the pre-collision
warning timing is changed, emer-
gency steering assist timing will
also be changed accordingly.
If late is selected, emergency steer-
ing assist would not operate in case
of an emergency.

■Situations in which the system may
not operate properly
●In some situations such as the follow-
ing, an object may not be detected by the radar sensor and front camera, preventing the system from operating
properly: • When a detectable object is approaching your vehicle
• When your vehicle or a detectable object is wobbling• If a detectable object makes an abrupt
maneuver (such as sudden swerving, acceleration or deceleration)• When your vehicle approaches a
detectable object rapidly • When a detectable object is not directly in front of your vehicle
• When a detectable object is near a wall, fence, guardrail, manhole cover,
vehicle, steel plate on the road, etc. • When a detectable object is under a structure
• When part of a detectable object is hidden by an object, such as large baggage, an umbrella, or guardrail

force (for region A) may not be obtained, preventing the system from performing properly:
• If the braking functions cannot operate to their full extent, such as when the brake parts are extremely cold,
extremely hot, or wet • If the vehicle is not properly main-tained (brakes or tires are excessively
worn, improper tire inflation pressure, etc.)• When the vehicle is being driven on a
gravel road or other slippery surface • When the road surface has deep wheel tracks
• When driving on a hill road
