Automatic braking is limited to approximately 30% of full pressure (0.3G deceleration) and is intended to provide a
smooth, gradual deceleration in follow mode conditions. Harsh braking by the target vehicle or following the target
vehicle down to very low speeds or to a halt will require driver override of the brakes.
While the radar sensor detects moving and stationary targets for assessment of the environment ahead, the system
does not react to or provide any control in situations other than follow mode conditions. Stationary or slow moving
vehicles (below 10 km/h), pedestrians, objects on the road and oncoming vehicles in the same lane are not recognized.
WARNING: The adaptive speed control system is not a collision warning or avoidance system and that, other than the
limited conditions of follow mode, driver intervention will be necessary to control the vehicle speed.
In follow mode, some situations may cause target ambiguities for the detection system. These situations include:
The nearby presence of a third vehicle when driving on a line slightly offset to the target vehicle.
Vehicles edging into the lane ahead which are not detected by the system until they have moved into the radar beam.
On the approach to, or exit from a bend, a target vehicle may be lost or a new target acquired as vehicles ahead change their
angular position with respect to the radar sensor. On a straight road, if the sensing vehicle is in follow mode below its selected
set speed, losing the target vehicle will cause the sensing vehicle to accelerate to this set speed. This acceleration is
undesirable either on, or entering a bend when the target is suddenly lost, and in this situation the system inhibits the
resumption of the set speed.
The speed control system compares vehicle speed data from the ABS system with the relative speed of an external object as
detected by the radar sensor to ascertain whether the object is stationary or not.
NOTE: If tires are fitted which are different in diameter from those specified for the vehicle, the vehicle speed calculated
by the ABS will not be the true road speed. This situation may cause stationary objects to be falsely identified as moving
vehicles and result in automatic deceleration on a clear road.
