Cruise Control
Any given speed above approxim ately
40 km /h /2 5 mph can be maintained
with the cruise control by operating
the switch.
1 Setting (touch sw itch)
Accelerating (hold sw itch)
2 Setting (touch switch)
Decelerating (hold switch)
Normally the vehicle is accelerated to
the desired speed with the accelera­
tor. Speed is set by briefly pushing
the sw itch to position 1 or 2, and the
accelerator can be released. The
speed can be increased (e.g. fo r
passing) by using the accelerator. As
soon as the accelerator is released,
the previously set speed will be
resum ed automatically.
If a set speed is to be increased or
decreased slightly, e.g. to adapt to
the traffic flow, retain sw itch in
position 1 or 2 until the desired speed
is reached. When the sw itch is
released, the newly set speed
remains.
