driver to toke over the situation.

p rompt
In certain situations, the braking power of the
adapt ive cruise control is not sufficient to
maintain an adequate distance from the ob-
ject ahead. In this situation, the adaptive
cruise control calls on
you as the dr iver to take
action .
The
driver intervention prompt alerts you vis-
ually and audibly .
- A red vehicle is shown in the instrument
cluster display ¢
fig. 122.
- The text DISTANCE! appears in the status
line.
- The indicator light in the Instrument cluster
blinks red.
- A warning tone sounds.
@ Tips
- If the adaptive cruise control initiates
braking, the hydraulic brake system is
under pressure. Therefore, the brake
pedal distance is shorter and the pedal
"feels" harder.
- Adaptive cruise control is switched off af-
ter pressing the footbrake . The speed
saved up this point can be resumed.
- To resume the saved speed, release the
brake pedal and press the control lever
¢ page 102, Turning adoptive cruise
control off temporarily .
- If you use the accelerator to go faster
than the speed of the object ahead of
you, the
driver intervention prompt will
not be accompanied by a warning signal.
- If the speed you previously set is exceed-
ed, the indicator light in the speedome-
ter w ill switch off.

General information
Applies to vehicles : with adaptive cruise contro l
Some driving situations which affect the func-
tion of the radar sensor are described below.
When driving, the adaptive cruise control is
governed by physical and system -specified
limits . Also, under certain circumstances, the
ACC system may react unexpectedly or late
from the driver's point of view. Therefore, al-
ways be attentive and intervene, if necessary:
- when driving around curves
r::;, page 109
- when vehicles in front are not in line with
your vehicle ,:;,page 109
