Pre-collision brake assist
■
When the system determines that the
possibility of a frontal collision is high,
the system applies greater braking
force in relation to how strongly the
brake pedal is depressed.
Pre-collision braking
■
If the system determines that the possi-
bility of a frontal collision is extremely
high, the brakes are automatically
applied to help avoid the collision or
reduce the impact of the collision.
Suspension control (if equipped)
■
When the system determines that the
possibility of a frontal collision is high,
the AVS (P.305) will control the
damping force of the shock absorbers
to help maintain an appropriate vehicle
posture.

WARNING
Limitations of the pre-collision system
■
● The driver is solely responsible for safe
driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-collision system
instead of normal braking operations
under any circumstances. This system
will not prevent collisions or lessen col-
lision damage or injury in every situa-
tion. Do not overly rely on this system.
Failure to do so may lead to an acci-
dent, resulting in death or serious
injury.
● Although this system is designed to
help avoid a collision or help reduce
the impact of the collision, its effective-
ness may change according to various
conditions, therefore the system may
not always be able to achieve the same
level of performance.
Read the following conditions care-
fully. Do not overly rely on this system
and always drive carefully.
• Conditions under which the system
may operate even if there is no possi-
bility of a collision: P.219
• Conditions under which the system
may not operate properly: P.220
Do not attempt to test the operation of
●
the pre-collision system yourself.
Depending on the objects used for
testing (dummies, cardboard objects
imitating detectable objects, etc.), the
system may not operate properly, pos-
sibly leading to an accident.
Pre-collision braking
■
When the pre-collision braking func-
●
tion is operating, a large amount of
braking force will be applied.
● If the vehicle is stopped by the opera-
tion of the pre-collision braking func-
tion, the pre-collision braking function
operation will be canceled after
approximately 2 seconds. Depress the
brake pedal as necessary.
