which reduces the amount of
attention necessary for safe
driving. The driver is solely
responsible for paying attention
to their surroundings and oper-
ating the steering wheel as nec-
essary to ensure safety. Also,
the driver is responsible for tak-
ing adequate breaks when
fatigued, such as when driving
for a long time.
●Failure to perform appropriate
driving operations and pay care-
ful attention may lead to an
accident.

Driving
WARNING
●Set the speed appropriately
according to the speed limit,
traffic flow, road conditions,
weather conditions, etc. The
driver is responsible for confirm-
ing the set speed.
●Even if the system is operating
correctly, the condition of a pre-
ceding vehicle as recognized by
the driver and detected by the
system may differ. Therefore, it
is necessary for the driver to
pay attention, assess risks, and
ensure safety. Over-reliance on
this system to drive the vehicle
safely may lead to an accident
resulting in death or serious
injury.
■Precautions for the driving
assist systems
Observe the following precau-
tions, as there are limitations to
the assistance provided by the
system. Over-reliance on this sys-
tem may lead to an accident
resulting in death or serious injury.
●Details of support provided for
the driver’s vision The dynamic
radar cruise control is only
intended to help the driver in
determining the distance
between the driver’s own vehi-
cle and a designated preceding
vehicle. It is not a system which
allows for careless or inattentive
driving, and is not a system
which assists in poor visibility
conditions. The driver must pay
attention to their surroundings,
even when the vehicle stops.
●Details of suppor t provided for
the driver’s judgement The
dynamic radar cruise control
determines whether the dis-
tance between the driver’s own
vehicle and a designated pre-
ceding vehicle is within a set
range. It is not capable of mak-
ing any other type of judgement.
Therefore, it is absolutely nec-
essary for the driver to remain
vigilant and to determine
whether or not t here is a possi-
bility of danger.
●Details of suppor t provided for
the driver’s operation The
dynamic radar cruise control
does not include functions
which will prevent or avoid colli-
sions with vehicles ahead of
your vehicle. Ther efore, if there
is ever any possibility of danger,
the driver must take immediate
and direct control of the vehicle
and act appropriately in order to
ensure safety.
■Situations in which the
dynamic radar cruise control
should not be used
Do not use the d ynamic radar
cruise control in the following situ-
ations. As the system will not be
able to provide appropriate con-
trol, using it may lead to an acci-
dent resulting in death or serious
injury.
●Roads where there are pedes-
trians, cyclists, etc.
●When driving on a highway or
expressway entrance or exit
●When the approach warning
sounds frequently
●Situations in which the sensors
may not operate properly:

ways.
WARNING
■For safe use
●Driving safely is solely the
responsibility of the driver.
Therefore, do not overly rely on
this system. The driver is solely
responsible for paying attention
to the vehicle’s surroundings
and driving safely.
●Set the speed appropriately
according to the speed limit,
traffic flow, road conditions,
weather conditions, etc. The
driver is responsible for confirm-
ing the set speed.
■Situations in which cruise
control should not be used
Do not use the cruise control in
the following situ ations. As the
system will not be able to provide

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 con-
tinue driving the vehicle,
such as if they have suf-
fered a medical emergency,
etc.
During LTA (Lane Tracing
Assist) control, if the sys-
tem does not detect driving
operations, such as if the
driver is not holding the
steering wheel, and deter-
mines 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 colli-
sion.
WARNING
■For safe use
●Driving safely is solely the
responsibility of the driver. Pay
careful attent ion to the sur-
rounding conditions in order to
ensure safe driving. The emer-
gency driving stop system is
designed to provide support in
an emergency where it is diffi-
cult for the dri ver to continue
driving, such as if they have had
a medical emergency. It is not
designed to support driving
while drowsy or in poor physical
health, or inattentive driving.
●Although the emergency driv-
ing 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 con-
tinue driving, its effectiveness
may change according to vari-
ous conditions. Therefore, it
may not always be able to
achieve the same level of per-
formance. Also, if the operating
conditions are not met, this
function will not operate.
●After the emergency driving
stop system operates, if driving
becomes possible again, imme-
diately begin driving again or, if
necessary, park the vehicle on
the shoulder of the road and set
a warning reflecto r and flare to
warn other drivers of your
stopped vehicle.
