suspension.
As uspension with the Adaptive Damping Sys-
tem provides improved driving comfort and con-
tinuously controls the calibration of the damp-
ers. The damping characteristic sa dapt to the
curren to perating and driving situation.
The damping is tuned individually to each wheel
and depends on: R
your driving style, e.g. sporty R
the road surface conditions R
the selected drive program ( Y
page 121).
Selecting the Comfort or Economy drive
programs In the Comfort and Economy drive programs,
the driving characteristic sofy our vehicle are

Problems with PARKTRONIC Problem
Possible causes/consequences and P Solutions
Only the red segments in
the PARKTRONIC warn-
ing display sa re lit. You
also hear aw arning tone
for approximately two
seconds.
PARKTRONIC is deacti-
vated after approx-
imately 20 seconds, and
the indicator lamp in the
PARKTRONIC button
lights up. PARKTRONIC has malfunctioned and has switched off. X
If problems persist, have PARKTRONIC checked at aq ualified spe-
cialist workshop.
Only the red segments in
the PARKTRONIC warn-
ing display sa re lit.
PARKTRONIC is deacti-
vated after approx-
imately five seconds. The PARKTRONIC sensors are dirty or there is interference. X
Clean the PARKTRONIC sensors ( Y
page 240).X
Switch the ignition back on.
The problem may be caused by an external source of radio or ultra-
sound waves. X
See if PARKTRONIC functions in ad ifferent location.
Parking Guidance
Important safety notes Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to measure
the road on both sides of the vehicle. As uitable
parking space is indicated by the parking sym-
bol. You receive steering instructions when
parking. You may also use PARKTRONIC
( Y
page 149).
Parking Guidance is only an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering, parking and exiting a
parking space. When maneuvering, parking or
pulling out of ap arking space, make sure that
there are no persons, animals or object sint he
area in which you are maneuvering.
G WARNING
If object sa re located above the detection
range, Parking Guidance may provide steering
instructions too soon. You may cause ac olli-
sion as ar esult. There is ar isk of an accident.
If object sa re located above the detection
range, stop and switch off Parking Assist. ! If unavoidable, you should drive over obsta-
cles such as curbs slowly and not at as harp
angle. Otherwise, you may damage the
wheels or tires.
When PARKTRONIC is deactivated, Parking
Guidance is also unavailable.
Parking Guidance may also display spaces not
suitable for parking, e.g.: R
where parking or stopping is prohibited R
in front of driveways or entrances and exits R
on unsuitable surfaces
Use Parking Guidance for parking spaces: R
that are paralle ltot he direction of travelR
that are on straight roads, not bends R
that are on the same level as the road, i.e. not
on the pavement, for example. Parking Guid-
ance may not detect flat curbs
Parking tips: R
On narrow roads, drive as close to the parking
space as possible. R
Parking spaces that are littered or overgrown
might be identified or measured incorrectly. R
Parking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly.152
