WARNING
●
Assisting the driver to measure follow-
ing distance
The dynamic radar cruise control is only
intended to help the driver in determin-
ing the following distance between the
driver’s own vehicle and a designated
vehicle traveling ahead. It is not a mecha-
nism that allows careless or inattentive
driving, and it is not a system that can
assist the driver in low-visibility condi-
tions. 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 deter-
mines 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 deter-
mine 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 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
control of the vehicle and act appropri-
ately in order to ensure the safety of all
involved.
■
To avoid inadvertent dynamic radar
cruise control activation
●
Switch the dynamic radar cruise con-
trol off using the “ON/OFF” button
when not in use.
■
Situations unsuitable for dynamic
radar cruise control

in any of the following situations.
Doing so may result in inappropriate
speed control and could cause an acci-
dent resulting in death or serious injury.

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
●

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 sensor or
camera sensor
●
In traffic conditions that require fre-
quent repeated acceleration and
deceleration

When an approach warning buzzer is
heard often
