WARNING
You could lose control of your vehicle if you
do the following while driving:
R adjust the driver's seat, head restraint,
steering wheel or mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint,
steering wheel and mirror and fasten your
seat belt before starting the engine. G
WARNING
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
distance from road users traveling behind,
e.g. when changing lane. There is a risk of an
accident.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder. 130

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:
R the electronic device that you connect has
a suitable connector and conforms to
standards specific to the country you are
in.
R the plug of the electronic device is plugged
correctly into 115 V power socket.
R the maximum wattage of the device to be
connected must not exceed 150 watts.
R the on-board power supply is within a
permissible voltage range.
R the 12 V sockets in the center console in
the front compartment (Y page 328) and in
the trunk are functional (Y page 329).
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.

WARNING
Electrostatic build-up can lead to the creation
of sparks, which could ignite the highly
explosive 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-
starting.
Always make sure that neither you nor the
battery is electrostatically charged. A build-
up of electrostatic charge can be caused, for
example:
R by wearing clothing made from synthetic
fibers
R due to friction between clothing and seats
R if you push or pull the battery across the
carpet or other synthetic materials
R if you wipe the battery with a cloth G
WARNING
During the charging process, a battery
produces hydrogen gas. If a short circuit
occurs or sparks are created, the hydrogen
gas can ignite. There is a risk of an explosion.
R Make sure that the positive terminal of a
connected battery does not come into
contact with vehicle parts.
R Never place metal objects or tools on a
battery.
R It is important that you observe the
described order of the battery terminals
when connecting and disconnecting a
battery.
R When jump-starting, make sure that the
battery poles with identical polarity are
connected.
R It is particularly important to observe the
described order when connecting and
disconnecting the jumper cables.
R Never connect or disconnect the battery
terminals while the engine is running. G
WARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with the skin, eyes or clothing.
Do not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash battery acid immediately with
water and seek medical attention. H
Environmental note Batteries contain dangerous
substances. It is against the
law to dispose of them with
the household rubbish. They
must be collected separately
and recycled to protect the
environment.
Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries to a qualified
specialist workshop or a
special collection point for
used batteries.
! Have the battery checked regularly at a
qualified specialist workshop.
Observe the service intervals in the
Maintenance Booklet or contact a qualified
specialist workshop for more information.
! You should have all work involving the
battery carried out at a qualified specialist
workshop. In the exceptional case that it is
necessary for you to disconnect the battery
yourself, make sure that:
R secure the vehicle to prevent it from
rolling away.
R you switch off the engine and remove the
SmartKey. Make sure the ignition is
switched off. Check that all the indicator
lamps in the instrument cluster are off.
Otherwise, electronic components, such
as the alternator, may be damaged.
R you first remove the negative terminal
clamp and then the positive terminal
clamp. Never swap the terminal clamps. 370
