Risk of accident
The vehicle can be braked when Distronic Plus
is activated. For this reason, deactivate Dis-
tronic Plus if the vehicle is to be set in motion
by other means (e.g. in a car wash or by tow-
ing). You can activate Distronic Plus in the follow-
ing circumstances:
R
about two minutes after the engine is star-
ted
R when the engine is running
R if you do not brake during the journey
R if your vehicle is not secured by the electric
parking brake
R if ESP ®
is activated
R if the automatic transmission is in position
D
R if the bonnet is closed
R if the driver's door is closed and you switch
from Pto Dor your seat belt is fastened.
Activating while driving
When driving at speeds below 30 km/h, you
can only activate Distronic Plus if the vehicle
in front has been detected and is shown in the
multi-function display. If the vehicle in front is
not shown in the multi-function display and is
no longer being detected, because it has
changed lanes, for example, Distronic Plus is
deactivated and you hear a warning tone.
X Briefly pull the cruise control lever towards
you ?or press it up :or down Ato the
pressure point.
Distronic Plus is selected.
X Keep the cruise control lever pressed
up : or down Auntil the desired speed
is set.
X Remove your foot from the accelerator
pedal.
Your vehicle adapts its speed to that of the
vehicle in front, but only up to the stored
speed.
i If you do not fully release the accelerator
pedal, the DISTRONIC PLUS suspended
message appears in the multi-function dis-
play. Then, the distance to a slower-moving
vehicle in front will not be governed. You
will be driving at the speed you determine
by the position of the accelerator pedal. Driving systems

cator lamp ;in the cruise control lever
lights up.
i The last speed stored remains stored until
you switch off the engine.
i Distronic Plus is not deactivated if you
depress the accelerator pedal. If you accel-
erate briefly to overtake, Distronic Plus
adjusts the vehicle's speed to the last
speed stored after you have finished over-
taking.
Distronic Plus is automatically deactivated if:
R you engage the electric parking brake or if
the vehicle is automatically secured with
the electric parking brake
R you are driving slower than 25 km/h and
there is no vehicle in front, or the vehicle in
front is no longer detected

you shift the automatic transmission to N,
P or R
R the vehicle is near a radio telescope facility:
only vehicles with COMAND and a naviga-
tion system* (Y page 411).
If Distronic Plus is deactivated, you will hear
a warning tone. You will see the DISTRONIC
PLUS off message in the multi-function dis-
play for approximately five seconds
Tips for driving with Distronic Plus The following contains descriptions of certain
road and traffic conditions in which you must
be particularly attentive. In such situations,
brake if necessary. Distronic Plus is then
deactivated.

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

spaces:
R that are closed in at the back.
R that are parallel to the direction of travel.
R that are at least 1.5 m wide.
R that are at least 1.0 m longer than your
vehicle.
A parking space is displayed while you are
driving past it, and until you are 15 m away
from it. Parking Guidance only displays park-
ing spaces on the front-passenger side as
standard. Parking spaces on the driver's side
are displayed as soon as the turn signal on
the driver's side is activated. If you wish to
park in a space on the driver's side, the indi-
cator on the driver's side must remain on until
reverse gear is engaged.
Parking The following instructions refer to parking in
a space on the front-passenger side. To park
in a space on the driver's side, mirror the
instructions.
Parking Guidance will emit a warning tone if
it detects an obstacle behind the vehicle
while you are parking. Stop immediately. The
parking space and the lane begin to flash in
the instrument cluster. Make sure that there
is no danger before continuing to drive. The display in the instrument cluster stops flash-
ing when Parking Guidance no longer detects
an obstacle. You can continue parking. G
Risk of accident
Parking Guidance is only an aid and may not
detect all obstacles. Parking Guidance may
not be able to detect objects in corners or on
smooth surfaces. Parking Guidance does not
