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.200
• Conditions under which the vehi-
cle-to-vehicle distance control mode
may not function correctly:

P.201
●
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 “ON/OFF” button when not
in use.
