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 paying careful attention to your surroundings.
The dynamic radar cruise control with full-speed range provides driving assistance to
reduce the driver's burden. However, there are limitations to the assistance provided.
Even when the system is functioning normally, the condition of the preceding vehicle as
detected by the system may differ from the condition observed by the driver. There-
fore, 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.
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 following distance
●
The dynamic radar cruise control with full-speed range is only intended to help the
driver in determining the following distance between the driver's own vehicle and a
designated vehicle traveling ahead. It is not a mechanism that allows careless or inat-
tentive 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 with full-speed range determines whether the fol-
lowing 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 pre-
vent 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
appropriately in order to ensure the safety of all involved.
To avoid inadvertent dynamic radar cruise control with full-speed range activation
■
Switch the dynamic radar cruise control with full-speed range off using the "ON/OFF"
button when not in use.
