● Vehicles with smart entry & start system:
If the wiper switch is turned to the position while the “ENGINE
START STOP” switch is in IGNITION ON mode, the wiper will operate
once to show that AUTO mode is activated.
If the wiper sensitivity is adjusted to higher, the wiper may operate once to
indicate the change of sensitivity.
● If the temperature of the raindrop sensor is 85°C (185°F) or higher, or
-40°C (-40°F) or lower, automatic operation may not occur. In this case,
operate the wipers in any mode other than AUTO.
■ If no windshield washer fluid sprays
Check that the washer nozzles are not blocked and if there is washer fluid in
the windshield washer fluid reservoir.
WARNING
■ Caution regarding the use of windshield wipers in AUTO mode
The windshield wipers may operate unexpectedly if the sensor is touched or
the windshield is subject to vibration in AUTO mode. Take care that your fin-
gers or anything else do not become caught in the windshield wipers.
■ Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the winds hield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.
NOTICE
■ When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■ When the washer fluid tank is empty
Do not use the washer when the washer fluid tank is empty. This may cause
the washer fluid pump to overheat.
■ When there is no windshield washer fluid spray from the nozzle

WARNING
The front sensor uses lasers to detect vehicles ahead of your vehicle. The
front sensor is classified as class 1M laser product according to the IEC
60825-1 standard. Under normal usage condi tions, these lasers are not harm-
ful to the naked eye. However, it is necessary to observe the following precau-
tions.
Failure to do so may result in the loss of eyesight or severe visual impairment.
● To avoid hazardous laser radiation exposure, never attempt to disassem-
ble the front sensor (e.g. remove the lenses). When disassembled, the
front sensor is classified as a class 3B laser product according to the IEC

NOTICE
■ 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 or illuminates. In that case, use the front
defroster to remove the fog, condensation, or ice. ( P. 334, 344)
●Do not attach stickers (including trans-
parent ones) or similar objects to the
outside of the windshield in front of the
front sensor (the shaded area shown in
the illustration).

PCS (Pre-Collision System)
■Pre-collision warning
When the system determines
that the possibility of a frontal
collision with a vehicle is high, a
buzzer will sound and a warning
message will be displayed on the
multi-information display to urge
the driver to take evasive action.
■ Pre-collision brake assist
When the system determines that the possibility of a frontal colli-
sion with a vehicle is high, the system applies greater braking force
in relation to how strongly the brake pedal is depressed.
: If equipped
The pre-collision system uses the front sensor to detect vehicles in
front of your vehicle. When the system determines that the possibil-
ity of a frontal collision with a vehicle is high, pre-collision warning
urges the driver to take evasive action and the potential brake pres-
sure will be increased to help the driver avoid the collision.
If the system determines that the possibility of a frontal collision
with a vehicle is extremely high, the brakes are automatically applied
to help avoid the collision or he lp reduce the impact to the vehicle
occupants and the vehicle in the collision.
The pre-collision warning timing can be changed or the system can be
enabled/disabled, as necessary, by operating the switch. ( P. 268)

■ Cancelation of the pre-collision braking
● If either of the following situations occur while the pre-collision braking
function is operating, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is tu rned 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.
■ Conditions under which the system may operate even if there is no
possibility of a collision
In the following situations the sensor may detect an object and cause the
system to determine that there is a possibility of a frontal collision and oper-
ate.
