control
General
information
An interrupted cruise control can be continued
by calling up the stored speed.
Make sure that the difference between current
speed and stored speed is not too large before
calling up the stored speed. Otherwise, uninj
tentional braking or accelerating may occur.
In the following cases, the stored speed value
is deleted and cannot be called up again:'yWhen the system is switched off.'yWhen the ignition is switched off.

limits
Detection
range
The detection capacity of the system and the
automatic braking capacity are limited.
Two-wheeled vehicles driving ahead of you for instance might not be detected.
Deceleration The system does not decelerate when a stajtionary obstacle is located in the same lane,
e.g., a vehicle at a red traffic light or at the end
of traffic congestion.
The system also does not react in the followj
ing situations:
'yFor pedestrians or similarly slow-moving
road users.'yFor red traffic lights.'yStationary objects.'yFor cross traffic.'yFor oncoming traffic.Seite 152ControlsDriving

Swerving
vehicles
A vehicle driving in front of you is not detecteduntil it is completely within the same lane as
your vehicle.
If a vehicle driving ahead of you suddenly
swerves into your lane, the system may not be able to automatically restore the selected disj
tance. It may not be possible to restore the sej
lected distance in certain situations, including if you are driving significantly faster than vehijcles driving ahead of you, for instance when
rapidly approaching a truck. When a vehicle
driving ahead of you is reliably detected, the
system requests that the driver intervene by
braking and carrying out evasive maneuvers, if
needed.
Unexpected
lane
change
If a vehicle ahead of you unexpectedly moves
into another lane from behind a stopped vehij
cle, you yourself must react, as the system does not react to stopped vehicles.
Cornering
If the desired speed is too high for a curve, the
speed is reduced slightly, although curves canj not be anticipated in advance. Therefore, drive
into a curve at an appropriate speed.
The system has a limited detection range. Sitj uations can arise in tight curves where a vehij
cle driving ahead will not be detected or will be
detected very late.
When you approach a curve the system may briefly report vehicles in the next lane due to
the bend of the curve. If the system decelerj
ates you may compensate it by briefly accelerj
ating.
After releasing the accelerator pedal the sysj tem is reactivated and controls speed indej
pendently.
Driving
away In some situations, the vehicle cannot drive off
automatically; for example:
'yOn steep inclines.'yFrom bumps in the road.
In these cases, step on the accelerator pedal.

areas.
Safety
information WARNING
The system does not release from the
personal responsibility to correctly assess the
traffic situation. Based on the limits of the sysj
tem, it cannot independently react to all traffic
situations. There is a risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively intervene in the rej
spective situations.'

WARNING
Signal
tones An intermittent tone indicates when the vehijcle is approaching an object. E.g., if an object
is detected to the left rear of the vehicle, a sigj
nal tone sounds from the left rear speaker.
The shorter the distance to the object, the
shorter the intervals.
If the distance to a detected object is less than
approx. 10 inches/25 cm, a continuous tone is sounded.
With front PDC: if objects are simultaneously located both in front of and behind the vehicle, an alternating continuous signal is sounded.
The signal tone is switched off, when selector
lever position P is engaged on vehicles with Steptronic transmission.
Volume
The ratio of the PDC signal tone volume to the entertainment volume can be adjusted.
