■
Cautions regarding the driv-
ing assist systems
Observe the following precau-
tions, 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.
●
Assisting the driver to measure
following distance
The dynamic radar cruise control
with full-speed range is only
intended to help the driver in
determining the following 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 vehi-
cle’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 does not
include functions which will pre-
vent or avoid collisions with vehi-
cles ahead of your vehicle.
Therefore, 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
the safety of all involved.
■
Situations unsuitable for
dynamic radar cruise control
with full-speed range
Do not use dynamic radar cruise
control with full-speed range in
any of the following situations.
Doing so may result in inappropri-
ate speed control and could
cause an accident resulting in
death or serious injury.
●
Roads where there are pedes-
trians, cyclists, etc.
●
In heavy traffic
●
On roads with sharp bends
●
On winding roads
●
On slippery roads, such as
those covered with rain, ice or
snow
●
On steep downhills, or where
there are sudden changes
between sharp up and down
gradients
Vehicle speed may exceed the
set speed when driving down a
steep hill.
●
At entrances to freeways and
highways
