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)

obtained, preventing the system from performing properly:
• If the braking functions cannot operate to their full extent, such as when the brake parts are extremely cold, extremely hot, or wet• If the vehicle is not properly maintained (brakes or tires are excessively worn,
improper tire inflation pressure, etc.) • When the vehicle is being driven on a gravel road or other slippery surface
