WARNING
● Even when the system is functioning
normally, the condition of the preced-
ing 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 accident,
resulting in death or serious injury.
● Switch the dynamic radar cruise con-
trol with full-speed range off using the
cruise control main switch when not in
use.
■ 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 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.
■ 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 high-
ways
● 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
front camera
● In traffic conditions that require fre-
quent repeated acceleration and
deceleration
