The Toyota Safety Sense consists of the following drive assist
systems and contributes to a safe and comfortable driving expe-
rience:
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 recognition 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 surround-
ings and driving safely.

WARNING
■To avoid malfunction of the camera sensor
Observe the following precautions.
Otherwise, the camera sensor may not operate properly, possibly leading to
an accident resulting in death or serious injury.
● Keep the windshield clean at all times.
• If the windshield is dirty or cover ed with an oily film, water droplets,
snow, etc., clear the windshield.
• If a glass coating agent is applied to t he 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 camera sensor.
• If the inner side of the windshield where the camera sensor is installed
is dirty, contact any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional.
● If the part of the windshield in front of the camera sensor is fogged up or
covered with condensation or ice, use the windshield defogger to remove
the fog, condensation or ice. ( P. 509)
● If water droplets cannot be properly removed from the area of the wind-
shield in front of the camera sensor by the windshield wipers, replace the
wiper insert or wiper blade.
• To replace the wiper insert: P. 613
• If the wiper blades need to be replaced, contact any authorized Toyota
dealer or repairer, or another dul y qualified and equipped professional.
● Do not attach window tinting to the windshield.
● Replace the windshield if it is damaged or cracked.

PCS (Pre-Crash Safety system)
◆Pre-crash warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.
The pre-crash safety system uses a radar sensor and camera
sensor to detect vehicles and pedestrians
*1 in front of your vehi-
cle. When the system determines that the possibility of a frontal
collision with a vehicle or pedestrian is high, a warning operates
to urge the driver to take evasive action and the potential brake
pressure is increased to help the driver avoid the collision. If the
system determines that the possibility of a frontal collision with
a vehicle or pedestrian is extremely high, the brakes are auto-
matically applied
*2 to help avoid the collision or help reduce the
impact of the collision.
The pre-crash safety system can be disabled/enabled and the warn-
ing timing can be changed. (P. 372)
*1: Depending on the region in which the vehicle was sold, the pedestrian
detection function may not be available. Contact any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional for
details.
*2: Depending on the region in which the vehicle was sold, the pre-crash
braking function (automatic braking function) may not be available. Con-
tact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional for details.

WARNING
■Limitations of the pre-crash safety system
● The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-crash safety system instead of normal braking opera-
tions under any circumstances. This system will not prevent collisions or
lessen collision damage or injury in every situation. Do not overly rely on
this system. Failure to do so may lead to an accident, resulting in death or
serious injury.
● Although this system is designed to help avoid a collision or help reduce
the impact of the collision, its effectiveness may change according to vari-
ous conditions, therefore the system may not always be able to achieve
the same level of performance.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• Conditions under which the system may operate even if there is no pos-
sibility of a collision: P. 376
• Conditions under which the system may not operate properly: P. 3 7 8
● Do not attempt to test the operation of the pre-crash safety system your-
self, as the system may not operate properly, possibly leading to an acci-
dent.
■ Pre-crash braking*3
●When the pre-crash braking function is operating, a large amount of brak-
ing force will be applied.
● If the vehicle is stopped by the operation of the pre-crash braking function,
the pre-crash braking function operation will be canceled after approxi-
mately 2 seconds. Depress the brake pedal as necessary.
● The pre-crash braking function may not operate if certain operations are
performed by the driver. If the accelerator pedal is being depressed
strongly or the steering wheel is bei ng turned, the system may determine
that the driver is taking evasive action and possibly prevent the pre-crash
braking function from operating.
● In some situations, while the pre-crash braking function is operating, oper-
ation of the function may be canceled if the accelerator pedal is depressed
strongly or the steering wheel is turned and the system determines that
the driver is taking evasive action.
● If the brake pedal is being depressed, the system may determine that the
driver is taking evasive action and possibly delay the operation timing of
the pre-crash braking function.
*3: Depending on the region in which the vehicle was sold, the pre-crash
braking function may not be available.

WARNING
■When to disable the pre-crash safety system
In the following situations, disable the system, as it may not operate prop-
erly, possibly leading to an accident resulting in death or serious injury:
● When the vehicle is being towed
● When your vehicle is towing another vehicle
● When transporting the vehicle via truck, boat, train or similar means of
transportation
● When the vehicle is raised on a lift with the hybrid system operating and

● When inspecting the vehicle using a drum tester such as a chassis dyna-
mometer or speedometer tester, or when using an on vehicle wheel bal-
ancer
● When a strong impact is applied to the front bumper or front grille, due to
an accident or other reasons
● If the vehicle cannot be driven in a stable manner, such as when the vehi-
cle has been in an accident or is malfunctioning
● When the vehicle is driven in a sporty manner or off-road
● When the tires are not properly inflated
● When the tires are very worn
● When tires of a size other than specified are installed

era sensor is temporarily installed to the vehicle
