WARNING
Before using dynamic radar cruise
■
control with full-speed range
● Driving safely is the sole responsibility
of the driver. Do not rely solely on the
system, and drive safely by always pay-
ing careful attention to your surround-
ings.
● The dynamic radar cruise control with
full-speed range provides driving
assistance to reduce the driver's bur-
den. However, there are limitations to
the assistance provided.
Read the following conditions care-
fully. Do not overly rely on this system
and always drive carefully.
• When the sensor may not be correctly
detecting the vehicle ahead: P.246
• Conditions under which the vehicle-
to-vehicle distance control mode may
not function correctly: P.247
4-5. Using the driving support systems
● Set the speed appropriately depend-
ing on the speed limit, traffic flow, road
conditions, weather conditions, etc.
The driver is responsible for checking
the set speed.
● 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 solely 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 setting to 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.
