PCS (Pre-Collision Sys-
tem)
The pre-collision system
uses sensors to detect
objects ( P.167) in the path
of the vehicle. When the
system determines that the
possibility of a frontal colli-
sion with a detectable
object 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 collision
is extremely high, the
brakes are automatically
applied to help avoid the
collision or help reduce the
impact of the collision.
The pre-collision system
can be disabled/enabled
and the warning timing can
be changed. ( P.176)
WARNING
■For safe use
●Driving safely is solely the
responsibility of the driver. Pay
careful attention to the sur-
rounding conditions in order to
ensure safe driving.
Never use the pre-collision sys-
tem in place of normal braking
operations. This system cannot
help avoid or reduce the impact
of a collision in every situation.
Over-reliance on this system to
drive the vehicle safely may
lead to an accident resulting in
death or serious injury.
●Although the pre-collision sys-
tem is designed to help avoid or
help reduce the impact of a col-
lision, its effectiveness may
change according to various
conditions. Therefore, it may not
always be able to achieve the
same level of performance.
Read the followin g items care-
fully. Do not overl y rely on this
system and always drive care-
fully.
