■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.

■ 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-
crash braking are also disabled. However, the pre-crash warning function
will still operate.
● The PCS warning light illuminates.

WARNING
■Limitations of the pre-crash safety system
● The driver is solely responsible for safe driving. Always drive safely, taking care to observe your surroundings.
Do not use the pre-crash safety sy stem instead of normal braking opera- tions under any circumstances. This system will not prevent collisions or lessen damage or injuries in every situation. Do not overly rely on this system. Failure to do so may lead to an accident, resulting in death orserious injury.
Although this system is designed to help avoid and reduce the impact of a collision, its effectiveness may change according to various conditions ( P. 230). As a result, the system may not always provide the same level of performance.
● The pre-crash braking function may not operate if certain operations are performed by the driver. If the accelerator pedal is being depressed strongly or the steering wheel is bei ng turned, the system may determine that the driver is taking evasive action and possibly prevent the pre-crashbraking function from operating.
● In some situations, while the pre-crash braking function is operating, oper- ation of the function may be canceled if the accelerator pedal is depressedstrongly or the steering wheel is turned and the system determines that the driver is taking evasive action.
● While driving, the system may recognize front obstacles, such as the crossing gate of a railway crossing, as a collision objects and operate thepre-crash brake.In the event that the vehicle gets caught within the railroad crossing, move the vehicle with the following actions and depending on the situation main- tain safety.
• Depress the accelerator pedal after the vehicle has stopped
• Strongly depress the accelerator pedal when decelerating ( P. 230)
• Turn the Pre-crash safety system OFF ( P. 229)
● A large amount of braking force is applied while the pre-crash braking function is operating. Additionally, as the vehicle may creep after the pre- crash braking function has operated, the driver should depress the brake pedal as necessary.

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
