Engaging the cruise control function
Before ACC can be used, it must first be put in
standby mode. To do so, press . The symbol
illuminates in the display and (---) indicate
that ACC is in standby mode.
Setting a speed
Use the
or buttons to store (set) the
vehicle's current speed. The set speed, for
example 55 mph, is shown in the display.
NOTE
Adaptive cruise control cannot be engaged
at speeds below 20 mph (30 km/h).
The “car” symbol illuminates
on the left side of the display
when the radar sensor
detects another vehicle
ahead. The distance to a vehi-
cle ahead is only regulated
when this symbol is illumi-
nated.
Adjusting the set speed
After a speed has been set, it can be increased
or decreased by using the
or buttons.
When the system is in active mode, the but-
ton has the same function as , but results in
a smaller increase in speed.
NOTE
•
If one of the adaptive cruise control but-
tons is pressed for more than approxi-
mately one minute, ACC will be deacti-
vated. The engine must then be
switched off and restarted to reset ACC.
•
In some situations cruise control cannot
be activated. Cruise Control
Unavailable is shown in the display,
see page 177.
Setting a time interval
The set time interval to vehicles ahead is
increased with
and decreased with .
The current time interval is shown briefly in the
display following adjustment.
Five different time intervals
can be selected and are
shown in the display as 1–5
horizontal bars. The greater
the number of bars, the longer
the time interval. At low
speeds, when the distance to
the vehicle ahead is short, ACC increases the
time interval slightly. In order to follow the vehi-
cle ahead as smoothly as possible, ACC allows
the time interval to vary considerably in certain
situations.
