react when you drive towards an obstacle
or something else on or near the road
t hat is not moving, such as vehicles stop-
ped in a traffic jam, a stalled or disabled
vehicle .
- Always remember that the adaptive
cruise control cannot detect a vehicle
that is driving towards you in your traffic
lane and that it cannot detect narrow ve-
hicles such as motorcycles and bicycles.
(D Tips
- For safety reasons, the stored speed is
deleted when the ignition is turned off .
- The Electronic Stabilization Program
(ESP) and the Anti-Slip Regulation (ASR)
cannot be deactivated when the adaptive
cruise control is switched on. If the ESP
and the Anti-Slip Regulation (ASR) has
been deactivated and you then switch on
the adaptive cruise control, the ESP func-
tion will also be activated automatically.
- Damage caused by accidents (e.g. if the
vehicle is damaged when parking) can af-
fect the radar sensor settings. This can
cause the system to malfunction or
switch off complete ly.
- The radar sensor cover is heated. In win-
ter cond itions, you should still check be-
fore driving to make sure it is free of ice
and snow. If necessary, clean the area
near the radar sensor carefully
9 fig. 109.
- To ensure that the radar sensor is not
blocked, foreign objects (e.g . stickers,
add-on parts) must not cover the area
near the radar sensor
9 fig. 109. The
area near the radar sensor must not be
painted, either.

Adaptive cruise control 101
How does adaptive cruise control work?
Appli es to veh icles: with adaptive cru ise control
Vehicles traveling ahead are detected with
the aid of a radar sensor .
Fig. 110 Radar sensor measurement range
A radar sensor is built into the front of the ve-
hicle
9 fig. 110, which is subject to certain
system limits~
page 110. Stationary objects
are not taken into consideration. The system
is intended to measure the distance to reflec-
tive surfaces. The system responds after the
distance measurement has taken place. If a
measurement is not possible, the system does
not respond .
Open road
When the road is clear, the adaptive cruise
control works like cruise control. It maintains
a constant target speed specified by the driv-
er.
Driving in traffic
If a vehicle driving ahead is detected, the
adaptive cruise control decelerates (within the
Limits of the system)

tervention prompt
and 9 page 110, System
limitations
to its speed and after adjusting,
tries to maintain the set distance from the ve-
hicle ahead . The vehicle may temporarily drive
slower than the set speed while adjusting
~ .&.in Description on page 100.
If the vehicle in front accelerates, adaptive
cruise control also accelerates up to the speed
that you have set .
Situation requiring driver intervention
In some situat ions you will have to use the
footbrake to slow the vehicle down in order to .,..
