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.

■ Conditions under which the system may operate even if there is no pos-
sibility of a collision

tem to determine that there is a possibility of a frontal collision and operate.
When there is an object (traffic sign, guard rail, etc.) by the roadside at
the entrance of a curve
When passing an oncoming vehicle on a curve
When passing an oncoming vehicle while making a left or right turn
When rapidly closing on a preceding vehicle
When rapidly closing on an electric toll gate barrier, parking area barrier,
or other barrier that opens and closes
When approaching an overpass, traffic sign, billboard, etc.
When the front part of the vehicle is raised or lowered
When the sensor is misaligned due to a strong impact being applied to
the sensor, etc.
When there is a structural object (billboard, street light, etc.) at the top of
an uphill road
When there is a metal object (manhole cover, steel plate, etc.) at the bot-
tom of a downhill road

When passing extremely close to an object (stopped vehicle, guardrail,
etc.)
■ Situations in which the pre-crash safety system may not function prop-
erly
The system may not function properly in the following situations:
When driving on roads with sharp bends or uneven surfaces
If a vehicle suddenly moves in front of your vehicle, such as at an inter-
section
If a vehicle suddenly cuts in front of your vehicle
If your vehicle is skidding
When the front part of the vehicle is raised or lowered
When the windshield is dirty or cover ed with raindrops, condensation, ice,
snow, etc.
When the sensor is misaligned due to a strong impact being applied to
the sensor, etc.
When a preceding vehicle is a poor reflector of laser (the rear part of the
vehicle lowered, very dirty, etc.)
When a very bright light, such as the sun or the headlights of oncoming
traffic, shines directly into the front sensor
When driving in inclement weather such as heavy rain, fog, snow or a
sand storm

■ If the PCS warning light flashes
The pre-crash safety system may be temporarily unavailable or there may be
a malfunction in the system.
● In the following situations, the warning light will be cleared and the system
will become operational when normal operating conditions return:
• When the area around the front sensor is hot, such as after the vehicle
has been parked in the sun
• When the windshield is fogged up or covered with condensation or ice
( P. 308, 317)
• If the area in front of the front sens or is obstructed, such as when the
hood is open
● If the PCS warning light continues to flash, the system may be malfunction-
ing. Have the vehicle inspected by any authorized Toyota dealer or repairer,
or another duly qualified and equi pped professional immediately.
■ If the TRC and VSC are disabled
● If the TRC and VSC are disabled (P. 262), pre-crash brake assist and pre-

LDA (Lane Depar ture Aler t)
While driving on a road that has lane markers, this system recognizes
the lane markers using a camera as a sensor to alert the driver when
the vehicle deviates from its lane.
If the system judges that the vehicle has deviated from its lane, it
alerts the driver using a buzzer and indications on the meter.
Front sensor
Press the LDA switch to activate
the system.
The LDA indicator will come on.
Press the switch again to turn the
LDA system off.
The LDA system will remain on or
off even if the engine switch is
turned to “ON” position (vehicles
without a smart entry & start sys-
tem) or IGNITION ON mode (vehi-
cles with a smart entry & start
system).

■Temporary cancelation of the LDA system functions
If any of the following occurs, the LDA system functions will be temporarily
canceled. The functions will resume after the necessary operating conditions
have returned.
● The turn signal lever is operated.
● The vehicle speed deviates from the operating range of the LDA system
functions.
● When the lane lines cannot be recognized while driving.
● When the lane departure warning sounds.
The lane departure warning function will not operate again for a several sec-
onds after it has been activated, even if the vehicle leaves the lane again.
■ The lane departure warning
Depending on the audio system sound level or air conditioning fan noise
while the audio system or air conditioning sy stem is in use, it may be difficult
to hear the warning sound.
■ After the vehicle has been parked in the sun
The LDA system may not be immediatel y available. When the temperature in
the cabin decreases and the temperature around the front sensor ( P. 236)
becomes suitable for its operation, the functions will begin to operate.
■ If there are lane markers on only one side of the vehicle
The lane departure warning will not operate for the side on which lane mark-
ers could not be recognized.
■ Conditions in which the function may not operate correctly
In the following situations, the front sensor may be unable to recognize lane
markers causing the lane departure warning function to operate incorrectly.
However, this does not indicate a malfunction.
● When driving through an area, such as a tollbooth, a crossing or before a
ticket checkpoint
● When driving on a sharp curve
● When lane markers are extremely narrow or extremely wide
● When the vehicle leans to one side an unusual amount due to a heavy load
or improper tire inflation pressure
● When the following distance between your vehicle and the vehicle ahead is
extremely short
● When the lane markers are yellow (These may be more difficult for the sys-
tem to recognize compared to white markers.)
● When the lane markers are broken, Botts’ dots (raised pavement markers)
or stones

Press the Automatic High
Beam switch.
The Automatic High Beam indica-
tor will come on green when the
headlights are turned on automati-
cally to indicate that the system is

assess the brightness of streetlights, the lights of oncoming and
preceding vehicles, etc., and automatically turns high beam on
or off as necessary.
