4-5. Using the driving support systems
CAUTION
Before using dynamic radar cruise control with full-speed range
Do not overly rely on vehicle-to-vehicle distance control.
Be aware of the set speed. If automatic deceleration/acceleration is not appropri-
ate, adjust the vehicle speed, as well as the distance between your vehicle and vehi-
cles ahead by applying the brakes etc.
Cautions regarding the driving assist systems
Observe the following precautions.
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 care-
less or inattentive driving, and it is not a system that can assist the driver in low-vis-
ibility 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 appropriate or not. 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 situa-
tion.
Assisting the driver to operate the vehicle
The dynamic radar cruise control with full-speed range has no 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.
