If the windshield needs to be replaced, contact 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 get the front sensor wet.
● Do not allow bright lights to shine into the front sensor.

◆Pre-crash warning
When the system determines
that the possib ility 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.
◆Pre-crash brake assist
When the system determines that the possibility of a frontal colli-
sion with a vehicle is high, the sy stem applies greater braking force
in relation to how strongly the brake pedal is depressed.
◆Pre-crash braking
When the system determines that the possibility of a frontal colli-
sion with a vehicle is high, the sy stem warns the driver. If the sys-
tem determines that the possibility of a collision is extremely high,
the brakes are automatically appli ed to help avoid the collision or
reduce the collision speed.
PCS (Pre-Crash Safety system)
: If equipped
The pre-crash safety system uses the front sensor to detect
vehicles in front of your vehi cle. When the system determines
that the possibility of a frontal co llision with a vehicle 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 is extremely high, the brakes are
automatically applied to help av oid 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. 255)

■Situations in which the system may not operate properly
● In some situations such as the following, a vehicle may not be detected by
the front sensor, preventing the system from operating properly:
• If an oncoming vehicle is approaching your vehicle
• When approaching the side or front of a vehicle
• If a preceding vehicle has a small rear end, such as an unloaded truck
• If a vehicle ahead is carrying a load which protrudes past its rear bumper
• If a vehicle ahead is irregularly shaped, such as a tractor or side car
• If the sun or other light is shining directly on a vehicle ahead
• If a vehicle ahead makes an abrupt maneuver (such as sudden swerving,
acceleration or deceleration)
• When suddenly cutting behind a preceding vehicle
• If a preceding vehicle has a low rear
end, such as a low bed trailer
• If a vehicle ahead has extremely high
ground clearance
• If a vehicle cuts in front of your vehicle
or emerges from beside a vehicle

• When the vehicle is hit by water, snow, dust, etc. from a vehicle ahead
• When driving through steam or smoke that may obscure vehicles ahead
• When driving in a place where the surrounding brightness changes sud-
denly, such as at the entrance or exit of a tunnel
• While driving on a curve and for a certain amount of time after driving on
a curve
• When a vehicle ahead is not directly
in front of your vehicle
• When driving in inclement weather
such as heavy rain, fog, snow or a

• The vehicle is wobbling.
• The vehicle is being driven at extremely high speeds.
• When driving on roads with sharp bends or uneven surfaces
• When a preceding vehicle is a poor reflector of laser
● In some situations such as the following, sufficient braking force 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 maintained (brakes or tires are excessively
worn, improper tire inflation pressure, etc.)
• When the vehicle is being driven on a gravel road or other slippery sur-
face
• If your vehicle is skidding

■ If the PCS warning light flashes or illuminates and a warning message is
displayed on the multi -information display
The pre-crash safety system may be tem porarily unavailable or there may be
a malfunction in the system.
● In the following situations, the warning light will turn off, the message will
disappear and the system will become operational when normal operating
conditions return:
• When the area around the front sensor is hot, such as in the sun
• When the windshield is fogged up or covered with condensation or ice
( P. 384)
• When driving in conditions where the front sensor cannot detect an
object, such as in the dark (at night on a road without street lights or other
lights, etc.), when bright light is shining into the sensor, or in snow or fog.
• When the front sensor or the area around ei ther sensor is cold, such as in
an extremely cold environment
• If the area in front of the front sensor is obstructed, such as when the
hood is open
● If the PCS warning light continues to flash or illuminate or the warning mes-
sage does not disappear, the system may be malfunctioning. Have the vehi-
cle inspected by any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional immediately.
■ If VSC is disabled
● If TRC and VSC are disabled (P. 307), the pre-crash safety brake assist
and pre-crash safety braking functions are also disabled. However, the pre-
crash safety warning function will still operate.
● The PCS warning light illuminates and “Pre-Crash Brake is disabled due to
VSC OFF.” is displayed on the multi-information display.

When driving on roads with white (yellow) lines, this function alerts the
driver when the vehicle might depart from its lane.
The LDA system recognizes visi-
ble white (yellow) lines with the
front sensor on the upper portion
of the windshield.
When the system determines that
the vehicle might depart from its
lane, a warning is displayed on
the multi-information display and
the warning buzzer sounds to
alert the driver.
When the warning buzzer sounds,
check the surrounding road situa-
tion and carefully operate the
steering wheel to move the vehicle
back to the center within the white
(yellow) lines.
