■Front sensor
Observe the following to ensure that the sensor operates correctly:
● Do not attach window tinting to the windshield.
● On cold days when there is a large temperature difference between the
vehicle interior and outside air temperatures, the windshield fogs up easily.
If the part of the windshield in front of the front sensor becomes fogged up
or covered with condensation or ice, the system temporarily stops working
and the PCS warning light flashes. In that case, use the front defroster to
remove the fog, condensation, or ice. ( P. 308, 317)
● Keep the windshield clean at all times. Also, even when using a glass
coating agent, if water droplets and so forth form on the windshield, use
the wipers to remove them.
The pre-crash safety system may not function properly if the windshield is
dirty or covered with an oily film, water droplets, snow, etc.
If the inner side of the windshield where the front sensor is installed is dirty,
do not attempt to remove the front sensor. Contact any authorized Toyota
dealer or repairer, or another dul y qualified and equipped professional.

■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.

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.
■ Situations unsuitable for LDA system
Do not use the LDA system in any of the following situations.
Otherwise, the system may not function correctly and could result in an
accident.
● When driving with tire chains, a spare tire, or similar equipment
● When there are objects or structures along the roadside that might be mis-
interpreted as lane markers (such as guardrails, a curb, reflector posts,
etc.)
● When driving on snowy roads
● When pavement lane markers are difficult to see due to rain, snow, fog,
sand, dirt, etc.
● When there are visible lines on the pavement from road repairs, or if the
remains of old lane markers are still visible on the road
● When driving on a road with lane closures due to maintenance, or when
driving in a temporary lane
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

■ Sounds and vibrations caused by the ABS, brake assist, TRC and VSC
systems
● A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, when the engine is started or just after the vehicle
begins to move. This sound does not indicate that a malfunction has
occurred in any of these systems.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■ Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automatically
re-enabled in the following situations:
● When the engine switch is turned to the “LOCK” position
● If only the TRC system is turned off, the TRC will turn on when vehicle
speed increases
If both the TRC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases.
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur, refrain
from excessive steering input or stop the vehicle and turn the engine off. The
EPS system should return to normal within 10 minutes.
