Adaptive cruise control -____________ __._ __ _
& WARNING (co ntinued )
• Always turn off adaptive crui se control when entering turn
lanes, highway ex it lanes and con struction zones or similar situa­
tions because the vehicle will automatically accele rate to the
stored speed .
• Never rest your foot on the accelerator pedal, especially when
the adaptive cruise control is being u sed because doing so will
override the braking function and prevent the brakes from being
applied by the system when it detect s a situation when the brake s
must be applied.
• Alway s remember that the adaptive cruise control has limits -
it does not react when you drive towards an obstacle or something
else on or near the road that is not moving, such as vehicles
stopped in a traffic jam , a stalled or disabled vehicle .
• Always remember that the adaptive cruise control cannot
detect a veh icle th at i s driving towards you in your traffic lane and
that it cannot detect narrow vehicles such as motorcycles and bicy­
cles .
[ i] Tips
• For safety reasons, the stored speed is deleted when the ignition
is turned off.
• The Electronic Stabilization Program (ESP) and the Ant i-Slip Regu ­
la tio n (A SR) c anno t be de activated when the adaptive cruise cont rol
is sw itched on .
If the ESP and the Anti -S lip Regulation (ASR) has been
de activ at ed an d yo u the n switch on the ad apt ive cruise cont rol, the
ESP fu nction w ill also be activated automatically.
• Dam age cau sed by accide nts (e.g. if the vehicle is dam age d whe n
park ing) can affect the rada r sensor settings. This can cause t he
sys tem to malfunc tion or switch off comple tely.
• The radar sensor cover is heated. In w inter conditions, you should

your foot off the accelerator pedal so that the recently selected mode
is also activated for the eng ine and transmission .
COMFORT
The COMFORT mode prov ides a comfo rtable vehi cle se tting . The
engine and automatic t ransm ission * respond in a balanced manner
when the accelerator pedal is pressed or released. Steering is light
and ind irect*, and adaptive dampers* provide a soft suspension . The
setting is ideal for driving on long stretches , such as on freeways.
AUTO
Full use of AUTO provides a comfortable, yet dynamic feel. The
sett ing is perfect for daily use .
DYNAMIC
DYNAMIC gives the vehicle a sporty feeling. The eng ine responds
quickly to accelerator pedal movements, and steer ing is sporty and
more direct. The adap tive dampers* are adjus ted to provide a stiffer
suspension and the automatic t ransmission* sh ifts at higher RPMs.
The setting is ideal for sporty driving .
