the function to be available.
Important safety notes
If you fail to adapt your driving style,
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot can neither reduce the risk of
an accident nor override the laws of physics.
It cannot take account of road, weather and
traffic conditions. DISTRONIC PLUS with
Steering Assist and Stop&Go Pilot is only an
aid. You are responsible for the distance to
the vehicle in front, for vehicle speed, for
braking in good time, and for staying in lane.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot does not detect road and traf-
fic conditions. If you are following a vehicle
which is driving towards the edge of the car-
riageway, your vehicle could come into con-
tact with the kerb or other road boundaries. In the case of deviations in road markings,
beware of other road users, e.g. cyclists, that are directly next to your vehicle.
Obstacles such as traffic pylons on the lane or
projecting out into the lane are not detected.
An inappropriate steering intervention, e.g.
after intentionally driving over a lane marking, can be corrected at any time if you steer
slightly in the opposite direction.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot cannot continuously keep your
vehicle in lane. In some cases, the steering
intervention is not sufficient to bring the vehi-
cle back to the lane. In such cases, you must steer the vehicle yourself to ensure that it
does not leave the lane. The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray
R there is glare, e.g. from oncoming traffic,
the sun or reflection from other vehicles
(e.g. if the road surface is wet)
R the windscreen is dirty, misted up, dam-
aged or covered, for instance by a sticker,
in the vicinity of the camera
R no, or several, unclear lane markings are
present for one lane, e.g. in a construction
area
R the lane markings are worn away, dark or
covered up, e.g. by dirt or snow
R the distance to the vehicle in front is too
small and the lane markings thus cannot be
detected
R the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge
R the road is narrow and winding
R there are highly variable shade conditions
on the road
The system is switched to passive and no lon- ger assists you by performing steering inter-
ventions if:
R you actively change lane
R you switch on the turn signal
R you take your hands off the steering wheel
or do not steer for a prolonged period of
time
i Steering Assist and Stop&Go Pilot are
activated again automatically after a lane
change is completed.
Steering Assist and Stop&Go Pilot do not pro- vide any support:
R on very sharp corners
R a loss of tyre pressure or a defective tyre
has been detected and displayed
Pay attention also to the important safety
notes for DISTRONIC PLUS (Y page 192). Driving systems

The steering interventions are carried out
with a limited steering moment. The system
requires the driver to keep his hands on the
steering wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you
with a visual warning. A steering wheel sym-
bol appears in the multifunction display. If you have still not started to steer and have not
taken hold of the steering wheel after five
seconds at the latest, a warning tone also
sounds to remind you to take control of the
vehicle. Steering Assist and Stop&Go Pilot are switched to passive. DISTRONIC PLUS
remains active.

Suspension setting
The electro-hydraulically controlled ABC sus- pension system works continuously. This
improves driving safety and comfort. The sys- tem detects the vehicle level and the vehicle
load and adjusts the setting accordingly. You
can also choose between a particularly sporty
(SPORT), a comfortable (COMFORT) as well as a comfortable mode with cornering func-
tion (CURVE).
The ABC suspension system is tuned individ-
ually to each wheel and depends on:
R your driving style, e.g. sporty
R the road surface condition, e.g. bumps
R your individual selection, i.e. sporty or com-
fort or comfort with the CURVE dynamic
cornering function
R the vehicle load
R the force of the side wind
Your selection remains stored even if you
remove the key from the ignition lock. The firmer suspension setting in SPORT mode
ensures even better contact with the road.
The steering response behaviour is sporty.
Select this mode on winding country roads or
motorways, for example.

function camera :at the top of the wind-
screen. This function is automatically active if
you select comfort suspension tuning. The
system is operational at speeds of up to
130 km/h.
This function allows bumps in the road sur-
face to be detected before the vehicle drives over them. The spring struts are then actu-
ated, with the result that chassis movements
are significantly reduced when driving over
bumps.
The system is deactivated when you select
the raised vehicle level, sports mode or the
dynamic cornering function.
The system may be impaired or may not func-
tion if:
R the road surface is insufficiently lit

General notes AIRMATIC is an air suspension system with
variable damping for improved driving com-
fort. All-round level control ensures the best
possible suspension and constant ground
clearance, even with a laden vehicle. When
you drive fast, the vehicle is lowered auto-
matically to improve driving safety and to
reduce fuel consumption. There is also the
option to manually adjust the vehicle level.
AIRMATIC consists of level setting, level con-
trol and the Adaptive Damping System ADS
PLUS.

General notes Active Parking Assist is an electronic parking
aid with ultrasound. It measures the road on
both sides of the vehicle. A parking symbol
indicates a suitable parking space. Active
steering intervention and brake application
can assist you during parking and when exit-
ing a parking space. You may also use
PARKTRONIC (Y page 209).
Important safety notes Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that no persons, animals or
objects are in the manoeuvring range.
When PARKTRONIC is switched off, Active
Parking Assist is also unavailable. G
WARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
cause you to collide with other road users.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
! If unavoidable, you should drive over
obstacles such as kerbs slowly and not at a
sharp angle. Otherwise, you may damage
the wheels or tyres.
Active Parking Assist may also display spaces not suitable for parking, e.g.:
R parking or stopping prohibitions
R in front of driveways or entrances and exits
R unsuitable surfaces 212
