2284-5. Using the driving support systems
PDA (Proactive driv-
ing assist)
When a detectable object
(P.229) is detected, the
proactive driving assist
operates the brakes and
steering wheel to help pre-
vent the vehicle from
approaching too close to
the object.
WARNING
■For safe use
Driving safely is solely the respon-
sibility of the driver.
●The proactive driving assist is
designed to provide some
assistance for regular braking
and steering operations, as well
as helping to prevent the vehicle
from approaching too close to a
detectable object. However, the
scope of this assistance is lim-
ited.
The driver should perform brake
and steering operations as neces-
sary. Read the following items
carefully. Do not overly rely on the
proactive driving assist and
always drive carefully.( P.230)
●The proactive driving assist is
not a system which reduces the
amount of attention necessary
for safe driving. Even if the sys-
tem is operating correctly, the
surrounding conditions as rec-
ognized by the driver and
detected by the system may dif-
fer. It is necessary for the driver
to pay attention, assess risks,
and ensure safety. Over-reli-
ance on this system to drive the
vehicle safely may lead to an
accident resulting in death or
serious injury.
●Proactive driving assist is not a
system which allows for inatten-
tive driving and is not a system
which assists in poor visibility
conditions. The driver is solely
responsible for paying attention
to their surroundings and driving
safely.
