• Alway s remember th at Adaptive Cru ise Control has limits - it
does not react when you drive toward s an obst acle or something
else on or near the road th at is not moving, such as vehicles
stopped in a traffic jam , a stalled or disabled vehicle.

detect a vehicle that is driving to wa rds you in your tr affic lane and
that it cannot det ect narrow vehicles such as motor cycles and
bicycles.
[ i ] Tips
• For safety reasons, t he stored speed is deleted when the ign it ion
is turned off .
• When Adaptive Cruise Control is switched on, the Electronic
Stabilization Program (ESP) is also automatically activated.
• Damage caused by accidents (e.g. if the vehic le is damaged
when parking) can affect the radar sensor settings. This can cause
the system to malfunct ion or switch off completely.
• In winter conditions, you should check the radar sensor cover
before driving to make sure it is free of ice and snow. If necessary ,
clean the area near the radar sensor carefully => page 139, fig . 151.
• To ensure that the radar sensor is not blocked, foreign objects
(e.g. stickers, larger license plate mounts, add -on parts) must not
cover the area near the radar sensor=>
page 139, fig . 151. The area
near the radar sensor must not be painted, either . •

How does Adaptive Cruise Control work?
Vehicles traveling ahead are detected with the aid of the
radar sensor.
Fig. 152 Radar sensor
me asuremen t range
A forward -look ing radar sens or in the fro nt bumper monitors the
traffic situation ahead . Vehicles moving in your direction can be
det ect ed up to a distance of about 140 yards (130 meters) but the
Adaptive Cruise Contro l cannot detect vehicles that are stopped or
stal led, obstac les that do not move or narrow vehic les like motorcy -
cles and bicycles.=> fig. 152.
Open road
When the road is clear, Adaptive Cruise Contro l works like cruise
control. The stored speed requested is main t ained .
Dri vi ng in tr a ffi c
If you start to catch up with a vehic le in fr ont of you, Adap t ive Cruise
Control automatically slows your vehic le to a speed that will help
you stay a safe distance back .
If the vehicle in front acce lerates, Adaptive Cruise Control also accel -
erates up to the speed that you have set . .,_
