Operation Manual

The distance between you and the vehicle
detected in front is maintained by a
variable setting. There are five steps which
are represented by horizontal bars
displayed in the information display. One
bar indicates the smallest gap and five
bars indicates the largest gap. These bars
are shown empty when in standby mode
and filled when in active mode.
If no vehicle is detected in front, then only
your vehicle is displayed in the information
display below the bars. The system will
maintain the set speed when conditions
permit. The set gap is maintained and
displayed.
If a vehicle is detected by the sensor, the
display will show another vehicle above
the horizontal bars:
E82312
This is a follow mode, and the system will
accelerate or decelerate as necessary to
maintain the set gap.
Pull switch E to decrease the gap or switch
D to increase the gap. The gap selected
will be represented by the number of bars
in the display.
Note: The recommended gap setting is four
or five bars.
Temporarily deactivating the
system
Note: The system is cancelled when the
gear lever is moved to a neutral position or
if the accelerator pedal or clutch is
depressed for a long period of time.
Press the brake pedal or pull switch F to
cancel the system. The system will return
to standby mode allowing you full manual
control of the vehicle. The set speed and
gap setting are retained in the memory.
Pull switch F again to resume. The system
will resume with the previously set speed
and vehicle gap setting if conditions permit.
Switching the system off
Press switch C to turn the system off.
Note: When deactivating the system by
pressing switch C, the stored speed is not
retained.
Automatic deactivation
Note: If the engine speed drops too low, a
message is displayed in the information
display instructing you to change down a
gear (manual transmission only). If you do
not follow this recommendation then the
system will go into automatic deactivation
mode.
Note: The system will not operate if
traction control has been switched off.
The system is dependent on various other
safety systems, for example ABS and ESP.
If any of these systems are malfunctioning
or reacting to an emergency, the system is
automatically deactivated.
In the event of automatic deactivation a
signal will sound and the message is
displayed in the information display. See
Information Messages (page 86). You
must then intervene and adapt your driving
and speed to vehicles in front.
An automatic deactivation can be due to
the:
• vehicle speed falling below 30 km/h
(20 mph)
• wheels losing traction
