Emergency Driving Stop System
The emergency driving stop system
is a system which automatically
decelerates and stops the vehicle
within its lane if the driver becomes
unable to continue driving the vehi-
cle, such as if they have suffered a
medical emergency, etc.
During LTA (Lane Tracing Assist)
control, if the system does not
detect driving operations, such as if
the driver is not holding the steer-
ing wheel, and determines the
driver is not responsive, the vehicle
will be decelerated and stopped
within its current lane to help avoid
a collision or reduce the impact of a
collision.
Vehicles with a Traffic Jam Assist:
The vehicle will also deceler-
ate/stop during the Traffic Jam
Assist controls, when no driver's
response to the vehicle's warning to
hold the steering wheel is detected.
WARNING
■ For safe use
● Driving safely is solely the responsibil-
ity of the driver. Pay careful attention to
the surrounding conditions in order to
ensure safe driving. The emergency
driving stop system is designed to pro-
vide support in an emergency where it
is difficult for the driver to continue
driving, such as if they have had a med-
ical emergency. It is not designed to
support driving while drowsy or in
poor physical health, or inattentive
driving.
● Although the emergency driving stop
system is designed to decelerate the
vehicle within its lane to help avoid or
help reduce the impact of a collision if
the system determines that it is difficult
for the driver to continue driving, its
effectiveness may change according
to various conditions. Therefore, it may
not always be able to achieve the same
level of performance. Also, if the oper-
ating conditions are not met, this func-
tion will not operate.
● After the emergency driving stop sys-
tem operates, if driving becomes pos-
sible again, immediately begin driving
again or, if necessary, park the vehicle
on the shoulder of the road and set a
warning reflector and flare to warn
other drivers of your stopped vehicle.
● After this system operates, passengers
should attend to the driver as neces-
sary and take appropriate hazard pre-
vention measures, such as moving to a
place where safety can be ensured,
such as the shoulder of the road or
behind a guardrail.
