NOTICE
■Front sensor
Observe the following to ensure that the sensor operates correctly:
● Do not attach window tinting to the windshield.
● On cold days when there is a large temperature difference between the
vehicle interior and outside air temperatures, the windshield fogs up easily.
If the part of the windshield in front of the front sensor becomes fogged up
or covered with condensation or ice, the system temporarily stops working
and the PCS warning light flashes. In that case, use the front defroster to
remove the fog, condensation, or ice. ( P. 308, 317)
● Keep the windshield clean at all times. Also, even when using a glass
coating agent, if water droplets and so forth form on the windshield, use
the wipers to remove them.
The pre-crash safety system may not function properly if the windshield is
dirty or covered with an oily film, water droplets, snow, etc.
If the inner side of the windshield where the front sensor is installed is dirty,
do not attempt to remove the front sensor. Contact any authorized Toyota
dealer or repairer, or another dul y qualified and equipped professional.
●Do not attach objects, such as stickers,
transparent stickers, etc., and so forth,
to the outer side of the windshield in
front of the front sensor (shaded area in
the illustration) or use a glass coating
agent.
A: From the top of the windshield to
approximately 10 cm (4.0 in.) below
the bottom of the front sensor
B: Approximately 20 cm (7.9 in.)
(Approximately 10 cm (4.0 in.) to the
right and left from the center of the
front sensor)
● Do not install or attach anything to the
inner side of the windshield under the
front sensor (shaded area in the illustra-
tion).
A: Approximately 10 cm (4.0 in.) (Start-
ing from the bottom of the front sen-
sor)
B: Approximately 20 cm (7.9 in.)
(Approximately 10 cm (4.0 in.) to the
right and left from the center of the
front sensor)

NOTICE
●If the windshield needs to be replaced, contact any authorized Toyota
dealer or repairer, or another dul y qualified and equipped professional.
● Replace the wiper blades immediately when necessary. If the area in front
of the front sensor is not appropriately wiped clean, the performance of the
sensor may decline.
When replacing the wiper blades is necessary, consult any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
● Do not install an antenna in front of the sensor.
● Do not spill liquid onto the sensor.
● Do not allow bright lights to shine into the sensor.
● Do not damage or let the lenses of the front sensor get dirty.
When cleaning the inner side of the windshield, do not let glass cleaner
contact the lenses. Also, do not touch the lenses.
For proper care of the lenses of the front sensor, contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional.
● Do not change the installation position or direction of the sensor or remove
it. The direction of the sensor is precisely adjusted.

PCS (Pre-Crash Safety system)
◆Pre-crash warning
When the system determines
that the possibility of a frontal
collision with a vehicle is high, a
buzzer will sound and the PCS
activation indicator will flash to
urge the driver to take evasive
action.
◆Pre-crash brake assist
When the system determines that the possibility of a frontal colli-
sion with a vehicle is high, the system applies greater braking force
in relation to how strongly the brake pedal is depressed.
: If equipped
The pre-crash safety system uses the front sensor to detect
vehicles in front of your vehicle. When the system determines
that the possibility of a frontal collision with a vehicle is high,
pre-crash warning urges the driver to take evasive action and
the potential brake pressure will be increased to help the driver
avoid the collision.
If the system determines that the possibility of a frontal collision
with a vehicle is extremely high, the brakes are automatically
applied to help avoid the collision or help reduce the impact to
the vehicle occupants and the vehicle in the collision.
The pre-crash warning timing can be changed or the system can be
enabled/disabled, as necessary, by operating the switch.
( P. 228)

◆Pre-crash braking
When the system determines that the possibility of a frontal colli-
sion with a vehicle is high, the system warns the driver. If the sys-
tem determines that the possibility of a collision is extremely high,
the brakes are automatically applied to help avoid the collision or
reduce the collision speed.
■Changing the pre-crash warning timing
Each time the PCS switch is
pressed, the warning timing
changes as follows:
Far (operation starts earlier)
Middle (default setting)
Near (operation starts later)
When the PCS switch is
pressed to turn the system on,
the PCS activation indicator will
turn on and the current warning
timing will be displayed on the
multi-information display.

■Operational conditions
The pre-crash safety system is enabled and determines that the possibility of
a frontal collision with a vehicle (e xcept motorcycles and bicycles) is high.
● Pre-crash warning:
• Vehicle speed is approximately 15 to 140 km/h (10 to 86 mph).
• The relative speed between your vehicle and the vehicle ahead is greater
than approximately 15 km/h (10 mph).
● Pre-crash brake assist:
• Vehicle speed is approximately 30 to 80 km/h (19 to 49 mph).
• The relative speed between your vehicle and the vehicle ahead is greater
than approximately 30 km/h (19 mph).
● Pre-crash braking:
• Vehicle speed is approximately 10 to 80 km/h (7 to 49 mph).
• The relative speed between your vehicle and the vehicle ahead is greater
than approximately 10 km/h (7 mph).
When the brake pedal is stepped on, the system judges if evasion actions are
being done by the driver and the start timing for pre-crash braking may be
delayed.
During the following, the driver operations takes precedence and the system
may not operate:
● The accelerator pedal is depressed strongly
● The steering wheel is turned sharply or abruptly
In case of the following, the system will not operate:
● If a battery terminal has been disconnected and reconnected and then the
vehicle has not been driven for a certain amount of time
● If VSC is disabled (only the pre-crash warning function will be operational)
● If the PCS warning light is flashing or illuminated
● When the shift position is in R
■ Cancelation of the pre-crash braking
● If either of the following situations occur while the pre-crash braking function
is operating, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is turned sharply or abruptly.
● If the vehicle is stopped by the operation of the pre-crash braking function,
the operation of the pre-crash braking function will be canceled after the
vehicle has been stopped for approximately 2 seconds.
