WARNING
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.
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 following
distance between the driver's own vehi-
cle and a designated vehicle traveling
ahead. It is not a mechanism that allows
careless or inattentive driving, 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 vigi-
lant 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 func-
tions which will prevent or avoid colli-
sions with vehicles ahead of your vehicle.
Therefore, if there is ever any possibility
of danger, the driver must take immedi-
ate and direct control of the vehicle and
act appropriately in order to ensure the
safety of all involved.
4-5. Using the driving support systems
■ 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 follow-
ing situations. Doing so may result in
inappropriate speed control and could
cause an accident resulting in death or
serious injury.
● Roads where there are pedestrians,
cyclists, etc.
● In heavy traffic
On roads with sharp bends
●
On winding roads
●
On slippery roads, such as those cov-
●
ered 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
When weather conditions are bad
●
enough that they may prevent the sen-
sors from detecting correctly (fog,
snow, sandstorm, heavy rain, etc.)
When there is rain, snow, etc. on the
●
front surface of the radar or front cam-
era
● In traffic conditions that require fre-
quent repeated acceleration and
deceleration
● When your vehicle is towing a trailer
or during emergency towing
● When an approach warning buzzer is
heard often
