WARNING
● 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.
■
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 acci-
dent 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
● During emergency towing
● When an approach warning buzzer is
heard often
