play the current warning timing in the multi-information display.
Each time the PCS switch is pressed in the displayed state, the timing
for the warning changes as follows:
If the operation timing setting has been changed, the setting will be
retained the next time the hybrid system is started.
Far
The warning will begin to oper-
ate earlier than with the default
timing.

■Operational conditions
The pre-crash safety system is enabled and determines that the possibility of
a frontal collision with a vehicle is high.
Each function is operational at the following speeds:
● Pre-crash warning:
• Vehicle speed is approximately 15 to 140 km/h (10 to 85 mph).
• The relative speed between your vehicle and a preceding vehicle is
approximately 15 km/h (10 mph) or more.
● Pre-crash brake assist:
• Vehicle speed is approximately 30 to 80 km/h (20 to 50 mph).
• The relative speed between your vehicle and a preceding vehicle is
approximately 30 km/h (20 mph) or more.
● Pre-crash braking:
• Vehicle speed is approximately 10 to 80 km/h (7 to 50 mph).
• The relative speed between your vehicle and a preceding vehicle is
approximately 10 km/h (7 mph) or more.
The system may not operate in the following situations:
● If a battery terminal has been disconnected and reconnected and then the
vehicle has not been driven for a certain amount of time
● If the shift lever is in R
● If VSC is disabled (only the pre-crash warning function will be operational)
■ Cancelation of the pre-crash braking
● If either of the following occur while the pre-crash braking function is operat-
ing, 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 braki ng function will be canceled after the
vehicle has been stopped for approximately 2 seconds.

■ If the PCS warning light flashes or illuminates (vehicles with mono-
chrome display)
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. 390)
• 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 either sensor is cold, such as in
an extremely cold environment
• 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 or illuminate, the system may be
malfunctioning. Have the vehicle inspected by any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer immediately.
■ If the PCS warning light flashes or illuminates and a warning message is
displayed on the multi-information di splay (vehicles with color display)
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 turn off, the message will
disappear and the system will beco me 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. 390)
• 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 either sensor is cold, such as in
an extremely cold environment
• 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 or illuminate or the warning mes-
sage does not disappear, the system may be malfunctioning. Have the vehi-
cle inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer immediately.

■ If VSC is disabled
● If TRC and VSC are disabled (P. 305), the pre-crash brake assist and pre-
crash braking functions are also disabled. However, the pre-crash warning
function will still operate.
● Vehicles with monochrome display: The PCS warning light illuminates.
● Vehicles with color display: The PCS warning light illuminates and “VSC
turned off. Pre-crash brake system unav ailable.” is displayed on the multi-
information display.

■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 immediately available. When the temperature in
the cabin decreases and the temperature around the front sensor ( P. 257)
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 oper ate 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 changing the tires
Depending on the tires used, sufficient performance may not be maintainable.
■ If the LDA indicator comes on in yellow (vehicles with monochrome dis-
play)
It may indicate a malfunction in the system. Contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
■ Warning messages for the LDA system (vehicles with color display)
Warning messages are used to indicate a system malfunction or to inform the
driver of the need for caution while driving.
■ Customization
P. 607
WARNING
■Before using the LDA system
Do not rely solely on the LDA system. The LDA system does not drive the
vehicle automatically, nor does it reduce the amount of care you need to
take. As such, the driver must always assume full responsibility for under-
standing his/her surroundings, for operati ng the steering wheel to correct
the driving line, and for driving safely.
Inappropriate or negligent driving could lead to an accident.
■ To avoid operating the LDA by mistake
Switch the LDA system off using the LDA switch when not in use.
