Recalling a speed memorised
beforehand
Tap the button, arrow 4. The memorised speed
is regained and maintained.
The memorised speed value is deleted and can
no longer be called up in the following
instances:
> When driving stability control systems are
intervening
> Cars with manual gearbox: when you shift
gears very slowly or shift to idle position
> Cars with automatic gearbox: when you
move the selector lever to position N
> When the ignition is switched off
Displays in the instrument cluster
1 Memorised speed
2 Selected speed is displayed briefly
If --- km/h or --- mph temporarily appears
in the instrument cluster display, it is pos-
sible that the system prerequisites for operation
are currently not met.
Calling up Check Control messages, see
page 69.<
Malfunction
The warning light comes on when the
system has failed. You can find more
information starting on page 142.
Active Cruise Control*
The principle
Active Cruise Control enables you to select a
desired speed which the vehicle automatically
maintains when the road ahead of you is clear.
Within the limits of its capability, the system
automatically adapts the car's speed to that of a
slower vehicle in front of you. You can specify
the distance to be maintained from the vehicle
in front in four stages. For safety reasons, the
distance is speed-dependent. To maintain dis-
tance, the system automatically reduces the
fuel supply, brakes slightly if necessary, and
accelerates again when the vehicle in front of
you starts to move more quickly. As soon as the
road in front of you is clear, the car is acceler-
ated to your desired speed. This speed will also
be maintained on downhill slopes, but may be
under-run on uphill slopes if engine output is
insufficient.
Read and carefully comply with the information
on the System limitations starting on page 59
so that you can understand the system's range
of applications and use the system appropri-
ately.
Braking sensation
> If you step on the brake pedal while the sys-
tem is braking, pedal sensation will be
slightly different from the usual.
> Possible noises during automatic braking
are normal.
Manual gearbox
You can shift gears while cruise control is acti-
vated. An indicator light notifies you that you
should shift gears when you drive for an
extended period at very high or very low engine
speeds, or the system is deactivated.
Range of applications
The ideal road-speed range for using the
system on well-developed motorways and sec-
ondary roads is about 80-140 km/h, approx.
50-85 mph. However, all local speed limit regu-
lations must be observed.
