9 Warning
The driver accepts fully
responsibility for the valid
following distance based on
traffic-, weather- and visibility
conditions.
Detecting the vehicle ahead
The green illuminated vehicle ahead
control indicator A displays in the
speedometer when the system is
detecting a vehicle in the driving path.
If this symbol does not display, or
displays briefly, adaptive cruise

by the driver when:
■ button y is pressed,
