PCS (Pre-Collision System)∗
∗: If equipped
When the radar sensor detects that a frontal collision is highly likely or
even unavoidable, safety systems such as the brakes and seat belts are
automatically engaged to lessen im pact as well as vehicle damage.
■Pre-collision seat belts (front seat belts only)
If the system detects that a collision is unavoidable, the system will
retract the seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or
loses control of the vehicle. ( →P. 9 1 )
However, when the VSC system is disabled, the system will not
operate in the event of skidding.
■ Pre-collision brake assist
When there is a high possibility of a frontal collision, the system
applies greater braking force in relation to how strongly the brake
pedal is depressed.
■ Pre-collision braking
When there is a high possibility of a frontal collision, the system
warns the driver using a warning light, warning display and buzzer. If
the system determines that a collision is unavoidable, the brakes are
automatically applied to reduce the collision speed. Pre-collision
braking can be disabled using the pre-collision braking off switch.

■When the “A/C ON” in the multi-information display (accessory meter) flashes
Press
the “A/C” button and turn off the cooling and dehumidification function and
turn it on again. There may be a problem in the air conditioning system if the indica-
tor light continues to flash. Turn the air conditioning system off and have it inspected
by your Lexus dealer.
■Air conditioning odors
●During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to be
emitted from the vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditio ning system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time immediately after the air conditioning system is started in AUTO mode.
■Customization
Settings (e.g. enable/disable automatic operation of the air conditioning compres-
sor when the “AUTO” switch ON) can be changed.
(Customizable features →P. 788)
CAUTION
■To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The dif-
ference between the temperature of the outside air and that of the windshield can
cause the outer surface of the windshield to fog up, blocking your vision.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the engine
is stopped.
