Before Using Dynamic Radar Cruise Control With Full-Speed Range - Lexus GS450h Owner's Manual

CAUTION
Dynamic radar cruise control with full-speed range is designed to detect motor vehi-
cles intended for use on public highways, with the exception of motorcycles. It will not
detect: stationary objects, pedestrians, motorcycles, bicycles, animals, and similarly
sized, or smaller, moving objects. The driver must always be aware of surroundings
and in control of the vehicle.

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 vehicle speed. If automatic deceleration/acceleration is not
appropriate, adjust the vehicle speed, as well as the distance between your vehicle
and vehicles 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.
The system, even in vehicle-to-vehicle distance control mode, only assists 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.
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.
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.
