G
Risk of accident
Distronic Plus cannot take account of road
and traffic conditions. If Distronic does not
recognise or no longer recognises the vehicle
in front, do not activate Distronic or, if it is
already active, deactivate it. This is especially
the case:
R before corners
R in filter lanes
R when changing to a lane with faster moving
traffic
R in complex driving situations or where the
lanes are diverted, e.g. at roadworks on a
motorway
Otherwise, Distronic Plus maintains the cur-
rent speed or accelerates up to the set speed.
Distronic Plus cannot take account of weather
conditions. Deactivate, or do not activate,
Distronic Plus:
R if the roads are slippery, snow-covered or
icy. The wheels could lose their grip when
braking or accelerating. The vehicle could
start to skid.
R if the sensors are dirty or there is poor vis-
ibility, e.g. due to snow, rain or fog. Dis-
tance control may be impaired.
Always pay attention to traffic conditions
even when Distronic Plus is activated. Other-
wise, you may fail to recognise dangers in
time, could cause an accident and injure your-
self and others.
! You must deactivate the radar sensor sys-
tem in certain countries and near radio
telescope facilities. Further information
can be found in the index under "Radar
sensor system".
Vehicles with COMAND and navigation sys-
tem*: you must deactivate the radar sensor
system near radio telescope facilities
(Y page 411). If you want Distronic Plus to assist you, the
radar sensor system must be activated and
operational.
If no car is driving in front of you, Distronic
Plus works like cruise control in the speed
range between 30 km/h and 200 km/h. If a
vehicle is driving in front of you, Distronic Plus
works in the speed range between 0 km/h
and 200 km/h.
Do not use Distronic Plus while driving on
roads with steep gradients.
G
Risk of accident
Distronic Plus brakes your vehicle at a maxi-
mum of 4m/s2
depending on its speed. This
corresponds to approximately 40% of your
vehicle's maximum brake force. You must
also apply the brakes yourself if this braking
power is not sufficient.
If Distronic Plus detects a risk of collision with
a vehicle in front, an intermittent warning tone
sounds. In addition, the ·distance warn-
ing lamp in the instrument cluster lights up.
Brake to avoid a collision.

Activating when driving towards a sta-
tionary vehicle
If the vehicle in front of you is stationary, you
can only activate Distronic Plus once your
vehicle is stationary as well.
X Briefly pull the cruise control lever towards
you ?.
Distronic Plus is selected.
i Distronic Plus can only be activated at
under 30 km/h if a vehicle in front has been
detected. Therefore, the Distronic Plus dis-
tance display in the instrument cluster
should be activated.
X Keep the cruise control lever pressed
up : or down Auntil the desired speed
is set.
i You can use the cruise control lever to set
the stored speed and the thumbwheel on
the cruise control lever to set the specified
minimum distance (Y page 239).
Pulling away
X If the vehicle in front pulls away: remove
your foot from the brake pedal.
X Briefly pull the cruise control lever towards
you ?.
or
X Accelerate briefly.
Your vehicle pulls away and adapts its
speed to that of the vehicle in front.
Driving
If there is no vehicle in front, Distronic Plus
operates in the same way as cruise control.
If a slower-moving vehicle is detected in front,
Distronic Plus causes your vehicle to brake
and maintain a preset distance to the vehicle
in front.
If Distronic Plus detects a faster-moving vehi-
cle in front, it increases the driving speed, but
only up to the stored speed. G
Risk of accident
If you depress the brake, Distronic Plus is
deactivated unless your vehicle is stationary.
Distronic Plus then no longer brakes your
vehicle. The driver remains fully responsible
for the vehicle's distance from other vehicles,
its speed and for braking in good time.
Stopping G
Risk of accident
The Distronic Plus braking effect is cancelled
and the vehicle could roll away if:
R Distronic Plus is deactivated using the
cruise control lever.
R you accelerate.
R the system or the power supply is disrup-
ted, e.g. due to battery failure.
R the electrical system in the engine com-
partment or the fuses have been tampered
with.
R the battery is disconnected. G
Risk of accident
Never get out of the vehicle when Distronic
Plus is activated.
Distronic Plus must never be operated or
deactivated by a passenger or from outside
the vehicle.
Distronic Plus does not replace the electric
parking brake and must not be used for park-
ing.
If you wish to leave the vehicle or park it,
deactivate Distronic Plus and secure the vehi-
cle against rolling away.
If Distronic Plus detects that the vehicle in
front is stopping, it brakes your vehicle until
it is stationary.
Once your vehicle is stationary, it remains
stationary and you do not need to depress the
brake.
i After a time, the electric parking brake
secures the vehicle and relieves the service
brake. 238

i The brake pedal does not return com-
pletely to the rest position while HOLD is
activated.
i If HOLD is not activated when you
depress the brake pedal, wait for a short
time and then try again. G
Risk of accident
The vehicle's brakes are applied when HOLD
is activated. For this reason, deactivate HOLD
if the vehicle is to be set in motion by other
means (e.g. in a car wash or by towing).
Deactivating HOLD HOLD is deactivated if:
R
you depress the accelerator pedal with the
transmission in position Dor R.
R you shift the automatic transmission to P.
R you release the brakes fully and apply them
again with a certain amount of pressure
until HOLD goes out in the instrument clus-
ter.

activated.
HOLD must never be operated or deactivated
by a passenger or from outside the vehicle. HOLD does not replace the electric parking
brake and must not be used for parking.
The HOLD braking effect is cancelled and the
vehicle can start moving if:
R HOLD is deactivated by depressing the
accelerator pedal or the brake pedal.
R there is a malfunction in the system or an
interruption in the power supply, e.g. bat-
tery failure.
R the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with.
R the battery is disconnected. G
Risk of accident
If you wish to leave the vehicle or park it,
deactivate HOLD and secure the vehicle
against rolling away. AIRMATIC*
Vehicle level Your vehicle automatically adjusts its ride
height to reduce petrol consumption and
improve driving safety.
The "Normal" and "Raised" vehicle levels can
be set.
Depending on the vehicle height that has
been set, the vehicle automatically adjusts its
height dependent on the current speed. The
vehicle is lowered by up to 10 mm as the
speed increases. As the speed is reduced, the
vehicle is raised up to the set vehicle height.
Setting the vehicle level manually
Select the "Normal" setting for normal road
surfaces and "Raised" for driving with snow
chains or on particularly poor road surfaces.
G
Risk of injury
Make sure that nobody is in the vicinity of the
wheel housing or under the vehicle while low-
ering the vehicle when it is stationary. Other-
wise, limbs could become trapped. 246

Parking Guidance*
Parking Guidance is an electronic parking aid
with radar sensors. The radar sensors are
used to measure the road on both sides of the
vehicle. It indicates suitable parking spaces
and provides steering instructions to help you
park in the indicated spaces. G
Risk of accident
Parking Guidance is only an aid. Parking
spaces detected may not be suitable for park-
ing due to, for example, parking prohibitions,
driveways, or unsuitable surfaces, etc.
The Parking Guidance display in the instru-
ment cluster is only a symbolic display of the
parking space as measured when first driving
past it. Later changes to the parking space are
not taken into account, e.g. if the vehicle
parked in front of or behind the space has
changed its position, or if obstacles are
moved into the parking space. Moving
objects, such as pedestrians and passing
vehicles, are not displayed.
Parking Guidance does not relieve you of the
responsibility to pay attention. If you rely
solely on Parking Guidance, you could cause
an accident and injure yourself and others.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. G
Risk of injury
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
! You must deactivate the radar sensor sys-
tem in certain countries and near radio
telescope facilities. Further information
can be found in the index under "Radar
sensor system".
Vehicles with COMAND and navigation sys-
tem*: the radar sensor system is automati-
cally deactivated near radio telescope facili-
ties (Y page 411). If you want Parking Guidance to assist you,
the radar sensor system must be activated
and operational.
Use Parking Guidance for parking spaces:
R
that are parallel to the direction of travel
R 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
Guidance may not detect flat kerbs.
Parking tips:
R on narrow roads, drive as close to the park-
ing space as possible.
R parking spaces which are littered, over-
grown or in front of trailers might not be
identified properly.
R pay attention to the Park Assist warning
messages when using Parking Guidance
(Y page 251).
R The position of your vehicle in the parking
space after using Parking Guidance
depends on the position and shape of the
vehicles parked in front and behind, and on
the conditions of the space. In some cases,
Parking Guidance may guide you too far
into a parking space, or not far enough into
it. In this case, you should cancel Parking
Guidance and correct the vehicle's posi-
tion.
Detecting parking spaces Parking Guidance is automatically activated
when you drive forwards. The system is
operational at speeds of up to approximately
40 km/h. While in operation, the system inde-
pendently locates and measures existing
parking spaces to both sides of the vehicle.
When driving at speeds below 16 km/h, you
will see the white parking space symbol as a
status indicator in the instrument cluster. If a
parking space is detected, the parking space
symbol changes colour to blue.254
