■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 86 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 (19 to 49 mph).
• The relative speed between your vehicle and a preceding vehicle is
approximately 30 km/h (19 mph) or more.
● Pre-crash braking:
• Vehicle speed is approximately 10 to 80 km/h (7 to 49 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)
● If the PCS warning light is flashing or illuminated
■ 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 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-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. 296)
• 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 dealer
or repairer, or another duly qualifi ed and equipped professional immediately.
■ If VSC is disabled
● If TRC and VSC are disabled (P. 246), the pre-crash brake assist and pre-
crash braking functions are also disabled. However, the pre-crash 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 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. 214)
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 operat ing 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 incorrect 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
any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional.
● Do not install or place anything on the hood or the grille. Also, do not install
a grille guard (bull bars, kangaroo bar etc.).

● High beam may be turned on or off when unexpected by the driver.
● In the situations below, the system may not be able to correctly detect the surrounding brightness levels, and may flash or expose nearby pedestrians to the high beam. Therefore, you shoul d consider turning the high beams on or off manually rather than relying on the Automatic High Beam system.
• In bad weather (rain, snow, fog, sandstorms, etc.) • The windshield is obscured by fog, mist, ice, dirt, etc.• The windshield is cracked or damaged.• The front sensor is deformed or dirty. • The front sensor temperature is extremely high. • Surrounding brightness levels are equal to those of headlights, tail lightsor fog lights.• Vehicles ahead have headlights or tail lights that are either switched off,dirty, are changing color, or are not aimed properly.• When driving through an area of intermittently changing brightness anddarkness. • When frequently and repeatedly driving ascending/descending roads, or roads with rough, bumpy or uneven surfaces (such as stone-pavedroads, gravel tracks, etc.).• When frequently and repeatedly taking curves or driving on a windingroad.• There is a highly reflective object ahead of the vehicle, such as a sign or a mirror. • The back of a vehicle ahead is highly reflective, such as a container on atruck.• The vehicle’s headlights are damaged or dirty.• The vehicle is listing or titling, due to a flat tire, a trailer being towed, etc.• The driver believes that the high beam may be causing problems or dis- tress to other drivers or pedestrians nearby.
■ If the Automatic High Beam indicator comes on in yellow
It may indicate a malfunction in the system. Contact any authorized Toyota dealer or repairer, or another duly qualified and equipped professional.
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 Automatic High Beam system
Observe the following to ensure that the Automatic High Beam functions
correctly.

WARNING
■The ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick roads.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten t he vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the
following situations:
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or roads with uneven surfaces
■ TRC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■ Hill-start assist control does not operate effectively when
● Do not overly rely on the hill-start assist control. The hill-start assist control
may not operate effectively on steep inclines and roads covered with ice.
● Unlike the parking brake, hill-start assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.
■ When the VSC is activated
The slip indicator flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■ When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRC/VSC systems off unless necessary.
