Position of the steering wheel and the
driver's seat for driving
The steering wheel and the driver's seat are
moved to the previously set position if:
Rthe driver's door is closed and you insert the
SmartKey into the ignition lock
Ryou close the driver's door when the ignition
is switched on
Ryou press the Start/Stop button once on vehi-
cles with KEYLESS-GO
iThe steering wheel and the driver's seat only
return to the last set position when the driving
position is stored after seat or steering wheel
adjustment.
The last position of the steering wheel or seat is
stored if:
Rthe ignition is switched off
Rthe setting is stored with the memory function
(Ypage 126).
Crash-responsive EASY-EXIT feature
If the crash-responsive EASY-EXIT feature is trig-
gered in an accident, the steering column will
move upwards when the driver's door is opened
or the SmartKey is removed from the ignition
lock. This makes it easier to exit the vehicle and
rescue the occupants.
The crash-responsive EASY-EXIT feature is only
operational if the EASY-EXIT/ENTRY feature is
activated in the multimedia system (see the sep-
arate operating instructions).

Important safety notes
GWARNING
You could lose control of your vehicle if you do the following while driving:
Radjust the driver's seat, head restraint,
steering wheel or mirrors
Rfasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine.
GWARNING
The exterior mirror on the front-passenger
side reduces the size of the image. Visible
objects are actually closer than they appear.
This means that you could misjudge the dis-
tance from road users traveling behind, e.g.
when changing lane. There is a risk of an acci-
dent.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder.

RUse only connector cables that are dry and
free of damage.
RWhen the ignition is off, make sure that the
115 V power socket is dry.
RHave the 115 V power socket checked or
replaced immediately at a qualified speci-
alized workshop if it is damaged or has been
pulled out of the trim.
RNever plug the connector cable into a 115 V
power socket that is damaged or has been
pulled out of the trim.
GDANGER
If you reach into the power socket or plug
inappropriate devices into the power socket,
you could receive an electric shock. There is a
risk of fatal injury.
Only connect appropriate devices to the
power socket.
!Note that work and repairs on the 115 V
power socket should only be carried out by
qualified specialist personnel.
General notes
The 115 V power socket provides an alternating
voltage of 115 V so that small electronic devices
can be connected. These devices, such as
games consoles, chargers and laptops, must not consume more than a maximum of 150 watts
altogether.
Requirements for operation of these devices:
Rthe electronic device that you connect has a
suitable connector and conforms to stand-
ards specific to the country you are in.
Rthe plug of the electronic device is plugged
correctly into 115 V power socket.
Rthe maximum wattage of the device to be
connected must not exceed 150 watts.
Rthe on-board power supply is within a permis-sible voltage range.
Rthe 12 V sockets in the center console in the
front compartment (Ypage 336) and in the
trunk are functional (Ypage 337).
Using the 115 V power socket
The 115 V socket is in the center console in the
rear compartment on vehicles with a rear bench
seat or electrically adjustable rear seats.

Battery (vehicle)
12 V battery – important safety notes
PLUG-IN HYBRID vehicles are equipped with a
12 V battery and a high-voltage battery. The fol-
lowing notes refer to the 12 V battery. Notes on
the high-voltage battery can be obtained in the
"High-voltage battery – important safety notes"
section (
Ypage 374).
Special tools and expert knowledge are required
when working on the battery, e.g. removal and
installation. You should therefore have all work
involving the battery carried out at a qualified
specialist workshop.
GWARNING
Work carried out incorrectly on the battery
can lead, for example, to a short circuit and
thus damage the vehicle electronics. This can
lead to function restrictions applying to
safety-relevant systems, e.g the lighting sys-
tem, the ABS (anti-lock braking system) or the
ESP
®(Electronic Stability Program). The oper-
ating safety of your vehicle may be restricted.
You could lose control of the vehicle, for
example:
Rwhen braking
Rin the event of abrupt steering maneuvers
and/or when the vehicle's speed is not
adapted to the road conditions
There is a risk of an accident.
In the event of a short circuit or a similar inci-
dent, contact a qualified specialist workshop
immediately. Do not drive any further. You
should have all work involving the battery car- ried out at a qualified specialist workshop.
For further information about ABS and ESP
®,
see (Ypage 68) and (Ypage 73).
All vehicles except Mercedes-AMG vehicles:
GWARNING
Electrostatic build-up can lead to the creation of sparks, which could ignite the highly explo-
sive gases of a battery. There is a risk of an
explosion.
Before handling the battery, touch the vehicle
body to remove any existing electrostatic
build-up.
The highly flammable gas mixture forms when
charging the battery as well as when jump-start-
ing.
Always make sure that neither you nor the bat-
tery is electrostatically charged. A build-up of
electrostatic charge can be caused, for exam-
ple:
Rby wearing clothing made from synthetic
fibers
Rdue to friction between clothing and seats
Rif you push or pull the battery across the car-
pet or other synthetic materials
Rif you wipe the battery with a cloth
GWARNING
During the charging process, a battery produ-
ces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.
RMake sure that the positive terminal of a
connected battery does not come into con- tact with vehicle parts.
RNever place metal objects or tools on a bat-
tery.
RIt is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting a battery.
RWhen jump-starting, make sure that the
battery poles with identical polarity are
connected.
RIt is particularly important to observe the
described order when connecting and dis-
connecting the jumper cables.
RNever connect or disconnect the battery
terminals while the engine is running.
GWARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with skin, eyes or clothing. Do
not inhale any battery gases. Do not lean over
the battery. Keep children away from batter-
ies. Wash away battery acid immediately with
