■Operational conditions
The pre-collision 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-collision warning:
• Vehicle speed is approximately 10 to 86 mph (15 to 140 km/h).
• The relative speed between your vehicle and a preceding vehicle is
approximately 10 mph (15 km/h) or more.
● Pre-collision brake assist:
• Vehicle speed is approximately 19 to 49 mph (30 to 80 km/h).
• The relative speed between your vehicle and a preceding vehicle is
approximately 19 mph (30 km/h) or more.
● Pre-collision braking:
• Vehicle speed is approximately 7 to 49 mph (10 to 80 km/h).
• The relative speed between your vehicle and a preceding vehicle is
approximately 7 mph (10 km/h) 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-collision warning function will be opera-
tional)
■ Cancelation of the pre-collision braking
●If either of the following occur while the pre-collision 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-collision braking func-
tion, the operation of the pre-collision braking function will be canceled after
the vehicle has been stopped for approximately 2 seconds.

■If the PCS warning light flashes or illuminates
The pre-collision system may be tempor arily 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
• 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 sensor 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 your Toyota dealer immedi-
ately.
■ If VSC is disabled
●If TRAC and VSC are disabled ( →P. 217), the pre-collision brake assist and
pre-collision braking functions are also disabled. However, the pre-collision
warning function will still operate.
● The PCS warning light illuminates.

■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 system 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. 173)
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

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 operating 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.
NOTICE
■To prevent damage to or incorr ect operation of the LDA system
● Do not modify the headlights or attach stickers to the surface of the lights.
● Do not modify the suspension. If your suspension needs repairs, contact
your Toyota dealer.
● Do not install or place anything on the hood or the grille. Also, do not install
a grille guard (bull bars, kangaroo bar etc.).

■Temporarily lowering sensor sensitivity
The sensitivity of the sensor can be temporarily lowered.
Turn the engine switch off while the following conditions are met.
• The headlight switch is in .
• The headlight switch lever is in low beam position.
• Automatic High Beam switch is on.
Turn the engine switch to the “ON” position.
Within 30 seconds after , repeat pulling the headlight switch lever to the
original position then pushing it to the high beam position quickly 10 times,
then leave the lever in high beam position.
If the sensitivity is changed, the Automatic High Beam indicator is turned on
and off 3 times.
Automatic High Beam (headlights) may turn on even if the vehicle is stopped.
WARNING
■ Limitations of the Automatic High Beam
Do not rely on the Automatic High Beam. Always drive safely, taking care to
observe your surroundings and turning high beam on or off manually if nec-
essary.
NOTICE
■Notes when using the Au tomatic High Beam system
Observe the following to ensure that the Automatic High Beam functions
correctly.
● Do not overload the vehicle.
● Do not modify the vehicle.

Driving
The fixed guide lines are very far out of alignment
The camera position is out of align-
ment.Have the vehicle inspected by your
Toyota dealer.
• The vehicle is tilted (there is a
heavy load on the vehicle, tire
pressure is low due to a tire punc-
ture, etc.)
• The vehicle is used on an incline.If this happens due to these causes,
it does not indicate a malfunction.
Back up while visually checking the
vehicle’s surroundings.
WARNING
■ When using the rear view monitor system
The rear view monitor system is a supplemental device intended to assist
the driver when backing up. When backing up, be sure to check visually
behind and all around the vehicle before proceeding.
Observe the following precautions to avoid an accident that could result in
death or serious injuries.
● Never depend on the rear view monitor system entirely when backing up.
The image and the position of the guide lines displayed on the screen may
differ from the actual state.
Use caution, just as you would when backing up any vehicle.
● Be sure to back up slowly, depressing the brake pedal to control vehicle
speed.
● The instructions given are only guide lines.
When and how much to turn the steering wheel will vary according to traf-
fic conditions, road surface conditions, vehicle condition, etc., when park-
ing. It is necessary to be fully aware of this before using the rear view
monitor system.
● When parking, be sure to check that the parking space will accommodate
your vehicle before maneuvering into it.
