WARNING
●If there is a large difference in temperature between the inside and outside
of the vehicle, such as in winter, t he windshield is likely to fog up easily. If
the part of the windshield in front of the front sensor is fogged up or cov-
ered with condensation or ice, the PCS warning light may illuminate and
the system may be temporarily disabled. In this case, use the windshield
defogger to remove the fog, etc. ( P. 442, 452)
● If the area of the windshield in front of the front sensor is covered with
water droplets, use the windshield wipers to remove them.
If the water droplets are not sufficiently removed, the performance of the
front sensor may be reduced.
● If water droplets cannot be properly removed from the area of the wind-
shield in front of the front sensor by the windshield wipers, replace the
wiper insert or wiper blade.
If the wiper inserts or wiper blades need to be replaced, contact any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
● Do not attach window tinting to the windshield.
● Replace the windshield if it is damaged or cracked.
If the windshield needs to be replaced, contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.

PCS (Pre-Crash Safety system)
◆Pre-crash warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound, the PCS activation indi-
cator will flash
*1 or a warning
message will be displayed in
the multi-information display
*2,
and the system will urge the
driver to take evasive action.
*1: Vehicles with monochrome display.
*2: Vehicles with color display.
: If equipped
The pre-crash safety system uses the front sensor to detect
vehicles in front of your vehicle. When the system determines
that the possibility of a frontal collision with a vehicle is high, a
warning operates to urge the driver to take evasive action and
the potential brake pressure is 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 help reduce
the impact of the collision.
The pre-crash safety system can be disabled/enabled and the warn-
ing timing can be changed. (P. 294)
