Crossing vehicles
DISTRONIC PLUS may detect vehicles that
are crossing your lane by mistake. Activating
DISTRONIC PLUS at traffic lights with
crossing traffic, for example, could cause
your vehicle to pull away unintentionally.
HOLD function
Important safety notes
GWARNING
When leaving the vehicle, it can still roll away
despite being braked by theHOLD function if:
Rthere is a malfunction in the system or in
the voltage supply.
Rthe HOLD function has been deactivated by
pressing the accelerator pedal or the brake
pedal, e.g. by a vehicle occupant.
Rthe electrical system in the engine
compartment, the battery or the fuses have
been tampered with.
Rthe battery is disconnected
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
the HOLD function and secure the vehicle
against rolling away.
!If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes
automatically in certain situations. To
prevent damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or other similarsituations:
Rwhen towing the vehicle

RACE START
Important safety notes
RACE START enables optimal acceleration
from a standing start. The precondition for
this is a suitable high-grip road surface.
RACE START is intended solely for activation
on dedicated race circuits.
iRACE START is only available in AMG
vehicles.
Conditions for activation
You can activate RACE START if:
Rthe doors, hood and the trunk lid are
closed.
Rthe engine is running and the transmission,
all-wheel drive clutch and the engine are at
operating temperature.
RSPORT handling mode is activated.

4MATIC (permanent four-wheel drive)
4MATIC ensures that all four wheels are
permanently driven. Together with ESP®, it
improves the traction of your vehicle
whenever a drive wheel spins due to
insufficientgrip.
If you fail to adapt yourdriving style, 4MATIC
can neither reduce the risk of accident nor
override the laws of physics. 4MATIC cannot
take account of road, weather and traffic
conditions. 4MATIC 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 your lane.
If a drive wheel spins due to insufficient grip:
ROnly depress the accelerator pedal as far
as necessary when pulling away.
RAccelerate less when driving.
!Never tow the vehicle with one axle
raised. This may damage the transfer case.
Damage of this sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remain either on the ground
or be fully raised. Observe the instructions
for towing the vehicle with all wheels in full
contact with the ground.
iIn wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tires(M+S tires), with snow
chains if necessary.

Parking tips:
RThe way yourvehicle is positioned in the
parking space after parkingis dependent
on various factors. These include the
position and shape of the vehicles parked
in front and behind it and the conditions of
the location. It may be the case that Active
Parking Assist guides you too far into a
parking space, or not far enough into it. In
some cases, it may also lead you across or
onto the curb. If necessary, you should
cancel the parking procedure with Active
Parking Assist.
RYou can also engage forward gear
prematurely.The vehicle redirects and
does not drive as far into the parking space.
Should a gear be changed too early, the
parking procedure will be canceled. A
sensible parking position can no longer be
achieved from this position.
Exitingaparking space
In order that Active Parking Assist can
support you whenyou exit the parking space:
Rthe border of the parking space must be
high enough.Acurb is too small, for
example.
Rthe border of the parking space must not
be too wide, as the position of the vehicle
must not exceed an angle of 45° to the
starting position as it is maneuvering into
the parking space.
Ra maneuvering distance of at least 3.3 ft
(1.0m) must be available.
Active Parking Assist can only assist you with
exiting a parking space if you have parked the
vehicle parallel to the direction of travel using
Active Parking Assist.
XStart the engine.
XSwitch on the turn signal in the direction
you are pulling away.
XShiftthe transmission to positionDorR.

has been completed and the rear view camera
has switched off does the flap close again. For
technical reasons, the flap may remain open
briefly after the rear view camera has been
deactivated. If you switch off the engine, the
flap will also close.
iThe text of messages shown in the
COMAND display depends on the language
setting. The following are examples of rear
view camera messages in the COMAND
display.
Observe the notes on cleaning
(Ypage 289).
Important safety notes
The rear view camera is only an aid. It is not
a replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering and
parking. When maneuvering or parking, make
sure that there are no persons, animals or
objects in the area in which you are
maneuvering.
Under the following circumstances, the rear
view camera will not function, or will function
in a limited manner:
Rthe tailgate is open
Rin heavy rain, snow or fog
Rat night or in very dark places
Rif the camera is exposed to very bright light
Rif the area is lit by fluorescent light or LED
lighting (the display may flicker)
Rif there is a sudden change in temperature,
e.g. when driving into a heated garage in
winter
Rif the camera lens is dirty or obstructed
Rif the rear of your vehicle is damaged. In
this event, have the camera position and
setting checked at a qualified specialist
workshop.
Activating/deactivating the rear view
camera
XTo activate:make sure that the SmartKey
is in position2in the ignition lock.
XMake sure that in the audio system/
COMAND, the "Activation by R gear"
function is selected; see the separate
operating instructions for the audio
system/COMAND.
XEngage reverse gear.
Guide lines are used to show the area
behind the vehicle in the Audio/COMAND
display.
To deactivate:the rear view camera is
deactivated if you:
Rselect transmission positionP(vehicles
with automatic transmission)
Rdrive forward ten meters
Rshift the transmission fromRto another
position after 15 seconds
Rdrive forwards at a speed of over5mph
(10 km/h)
Displays in the Audio/COMAND display
The rear view camera may show a distorted
view of obstacles, show them incorrectly or
not at all. The rear view camera does not show
objects in the following positions:
Rvery close to the rear bumper
Runder the rear bumper
Rin the area immediately above the tailgate
handle
!Objects not at ground level may appear to
be further away than they actually are, e.g.:
Rthe bumper of a parked vehicle
Rthe drawbar of a trailer
Rthe ball coupling of a trailer tow hitch
Rthe rear section of an HGV

message appears in the multifunction
display.
XIf necessary, take a break.
XPress theorbutton to confirm
the message.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you
do not take a break, you will be warned again
after 15 minutes at the earliest. The
preconditionfor this is that
ATTENTION ASSIST still detects typical
indicators of fatigue or increasing lapses in
concentration.
ATTENTION ASSIST is reset when you
continue your journey and starts assessing
your tiredness again if:
Ryou switch off the engine.
Ryou take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break.

Speed Limit Assist
General notes
Speed Limit Assist shows you detected speed
limits in the multifunction display.Data from
the navigation system is also used for this
purpose. If a traffic sign indicating a speed
limit or the end of a speed limit is detected,
it is shown in the multifunction display. If
Speed Limit Assist does notdetectany traffic
signs, the speed limit from the digital road
map is used and shown in the display.
Speed Limit Assist detects the traffic signs
with a camera attached behind the top of the
windshield.
Speed Limit Assist camera
Important safety notes
Speed Limit Assist is only an aid and does not
always detect traffic signs with information
aboutthe maximum permissible speed.
Traffic signs always have priority over the
Speed Limit Assist display.
The system may be impaired or may not
function if:
Rthere is poor visibility, e.g. due to snow,
rain, fog or spray
Rthere is glare, e.g. from the sun or from
oncoming traffic
Rthe windshield is dirty, fogged up or
covered, for instance by a sticker, in the
vicinity of the camera
Rthe traffic signs are covered, for instance
by dirt, snow or trees
Rthe traffic signs are poorly illuminated
Rthere are ambiguous traffic signs, for
instance near roadworks or on multi-lane
