Before using dynamic radar cruise
control with full-speed range
Driving safely is the sole responsibility of
the driver. Do not rely solely on the sys-
tem, and drive safely by always paying
careful attention to your surroundings.
The dynamic radar cruise control with
full-speed range provides driving assis-
tance to reduce the driver’s burden.
However, there are limitations to the
assistance provided.
Set the speed appropriately depending
on the speed limit, traffic flow, road con-
ditions, weather conditions, etc. The
driver is responsible for checking the set
speed.
Even when the system is functioning nor-
mally, the condition of the preceding
vehicle as detected by the system may
differ from the condition observed by the
driver. Therefore, the driver must always
remain alert, assess the danger of each
situation and drive safely. Relying on this
system or assuming the system ensures
safety while driving can lead to an acci-
dent, resulting in death or serious injury.
■
Cautions regarding the driving assist
systems
Observe the following precautions, as
there are limitations to the assistance
provided by the system.
Failure to do so may cause an accident
resulting in death or serious injury. B

E ●
Assisting the driver to measure follow-
ing distance
The dynamic radar cruise control with
full-speed range is only intended to
help the driver in determining the fol-
lowing distance between the driver’s
own vehicle and a designated vehicle
traveling ahead. It is not a mechanism
that allows careless or inattentive driv-
ing, and it is not a system that can assist
the driver in low-visibility conditions. It
is still necessary for driver to pay close
attention to the vehicle’s surroundings. ●
Assisting the driver to judge proper
following distance
The dynamic radar cruise control with
full-speed range determines whether
the following distance between the
driver’s own vehicle and a designated
vehicle traveling ahead is within a set
range. It is not capable of making any
other type of judgement. Therefore, it
is absolutely necessary for the driver to
remain vigilant and to determine
whether or not there is a possibility of
danger in any given situation. ●
Assisting the driver to operate the
vehicle
The dynamic radar cruise control with
full-speed range has limited capability
to prevent or avoid a collision with a
vehicle traveling ahead. Therefore, if
there is ever any danger, the driver
must take immediate and direct con-
trol of the vehicle and act appropri-
ately in order to ensure the safety of all
involved.
■
To avoid inadvertent dynamic radar
cruise control with full-speed range
activation
Switch the dynamic radar cruise control
with full-speed range off using the “ON/
OFF” button when not in use.
