WARNING
QToyota 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 pay-ing attention to the vehicle’s sur-
roundings and driving safely.

OIn 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
QTo 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.
OKeep 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.

3105-5. Using the driving support systems
OIn the following situations, if the situation has changed (or the vehicle has been
driven for some time) and the normal operating conditions are detected, the mes-
sage will disappear and the system will become operational.
If the message does not disappear, contact any authorized Toyota 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 vehicle, such as when
driving in the dark, snow, or fog, or when bright lights are shining into the front
camera
• Depending on the conditions in the vicinity of the vehicle, the radar may judge the
surrounding environment can not be properly recognized. In that case, “Pre-Colli-
sion System Unavailable” is displayed.
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 as 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 Unavail-
able” is displayed.Check whether there is attached materi-
als on the radar sensor and radar sensor
cover, and if there is, remove it.

Driving
*: If equipped
The system can detect the follow-
ing:
Vehicles
Bicyclists
Pedestrians
QPre-collision 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.
QPre-collision brake assist
When the system determines that
the possibility of a frontal collision is
high, the system applies greater
braking force in relation to how
strongly the brake pedal is
depressed.
QPre-collision braking
If the system determines that the
possibility of a frontal collision is
extremely high, the brakes are
automatically applied to help avoid
the collision or reduce the impact of
the collision.
PCS (Pre-Collision Sys-
tem)
*
The pre-collision system uses
a radar sensor and front cam-
era to detect objects (P.311)
in front of the vehicle. When
the system determines that the
possibility of a frontal collision
with an object is high, a warn-
ing 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 sys-
tem determines that the possi-
bility of a frontal collision with
an object is extremely high,
the brakes are automatically
applied to help avoid the colli-
sion or help reduce the impact
of the collision.
The pre-collision system can be
disabled/enabled and the warn-
ing timing can be changed.

driver. The warning stops when the sys-
tem determines that the driver holds the
steering wheel. Always keep your hands
on the steering wheel when using this
system, regardless of warnings.
OWhen the system determines that the
driver is driving without holding the
steering wheel while the system is
operating
If the driver continues to keep their
hands off of the steering wheel, the
buzzer sounds, the driver is warned and
the function is temporarily canceled.
This warning also operates in the same
way when the driver continuously oper-
ates the steering wheel only a small
amount.
The buzzer also sounds even if the alert
type is set to “Steering wheel vibration”.
OWhen the system determines that the
vehicle may not turn and instead
depart from its lane while driving
around a curve
Depending on the vehicle condition and
road conditions, the warning may not
operate. Also, if the system determines
that the vehicle is driving around a
curve, warnings will occur earlier than
during straight-lane driving.
OWhen the system determines that the
driver is driving without holding the
steering wheel while the steering
wheel assist of the steering assist
function is operating.
If the driver continues to keep their
hands off of the steering wheel and the
steering wheel assist is operating, the
buzzer sounds and the driver is warned. Each time the buzzer sounds, the con-
tinuing time of the buzzer becomes lon-
ger.
The buzzer also sounds even if the alert
type is set to “Steering wheel vibration”.
QVehicle sway warning function
When the system determines that the
vehicle is swaying while the vehicle
sway warning function is operating, a
