2013 MERCEDES-BENZ S-CLASS SEDAN Engine light

term "sliding sunroof" refers to both types of
sliding sunroof.
G
WARNING
When opening or closing the sliding sunroof,
make sure that there is no danger of anyone
being harmed by the opening/closing
procedure.
The sliding sunroof is equipped with
automatic
operation and the anti-entrapment
feature. If the movement of the sliding sunroof
is blocked during the closing procedure, the
sliding sunroof will stop and open slightly.
The sliding sunroof operates differently when
the sliding sunroof switch is pressed and held.
See the "Problems with the sliding sunroof"
section for more details.
The opening/closing procedure of the sliding
sunroof can be immediately halted by
releasing the sliding sunroof switch or, if the
sliding sunroof switch was moved past the
resistance point and released, by moving the
sliding sunroof switch in any direction. G
WARNING
The sliding sunroof is made out of glass. In the
event of an accident, the glass may shatter.
This may result in an opening in the roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening. Such an
opening

also presents a potential for injury for
occupants wearing their seat belts properly,
as entire body parts or portions of them may
protrude from the passenger compartment.
! Only open the sliding sunroof if it is free
of snow and ice. Otherwise, malfunctions
may occur.
Do not allow anything to protrude from the
sliding sunroof. Otherwise, the seals could
be damaged.
! The weather can change abruptly. It could
start to rain or snow. Make sure that the
sliding sunroof is closed when you leave the
vehicle. The vehicle electronics can be damaged if water enters the vehicle
interior.
i Resonance noises can occur in addition
to

the usual airflow noises when the sliding
sunroof is open. They are caused by minor
pressure fluctuations in the vehicle interior.
Change the position of the sliding sunroof
or open a side window slightly to reduce or
eliminate these noises. Operating the sliding sunroof
Opening and closing i
You can continue to operate the sliding
sunroof after switching off the engine or
removing the SmartKey from the ignition
lock.

This function is available for up to five
minutes or until the driver's or front-

You can install new map software yourself
which, depending on the scope, may consist
of one or more DVDs.
The installation process can take between
10
and 120 minutes, depending on the scope
of the map software. If the radio is switched
on before you start the installation process,
you can still adjust the volume. You can also
use COMAND to operate automatic climate
control and to cancel the process. Other
functions are not operational. If possible,
carry out the installation when the vehicle is
stationary. The DVD read speed is higher
when the vehicle is stationary than when it is
in motion, so less time is required. If the
starter battery is not sufficiently charged,
COMAND may end the process automatically
in order to protect the battery. Therefore, let
the engine idle during the installation
process. G
WARNING
Never leave the engine running in enclosed
spaces. The exhaust gases contain toxic
carbon

monoxide. Breathing in exhaust fumes
is a health hazard and can lead to
unconsciousness or death.

Notes on handling DVDs
R Only hold DVDs by the edge.
R Handle DVDs carefully to prevent reading
errors.
R Avoid getting scratches, fingerprints and
dust on DVDs. R
Use a commercially-available cleaning
cloth to clean discs. When cleaning CDs,
you should wipe in straight lines from the
center outwards rather than in a circular
motion.
R Place DVDs back in their cases after use.
R Protect

DVDs from heat and direct sunlight.
Map software copy protection
Map software for COMAND is subject to a
charge. The map software has just one
activation code which is usable in one vehicle
only, and is not transferable. You can obtain
the six-digit activation code from your
authorized Mercedes-Benz Center. If you
have lost the activation code, or if COMAND
does not accept the activation code that you
have received, contact your authorized
Mercedes-Benz Center.
Your vehicle is supplied with map software at
the factory. Depending on the country, map
software for your region is either pre-installed
(Europe/USA) or the map software is
supplied as a DVD (all other countries). You
do not require an activation code for the map
software that is provided with your vehicle.
If the map software on your vehicle has been
installed at the factory and you wish to
reinstall it, this also does not necessitate
entry of the activation code.
Installation process
X Load the map software DVD in the DVD
drive ( Y page 220).
COMAND checks the DVD and shows a
corresponding message in the display.
Map software is not compatible with the
navigation system
You

will see a message that the map software
cannot be installed.
X To confirm the message: press W.

Important safety notes
Xenon bulbs If your vehicle is equipped with Xenon bulbs,
you can recognize this by the following: the
cone of light from the Xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the lights must be switched on
before starting the engine.
G
DANGER
Xenon bulbs carry a high voltage. You could
get
an electric shock and be seriously or even
fatally injured if you touch the electric
contacts on Xenon bulbs. Therefore, never
remove the cover from Xenon bulbs.
Do not change Xenon bulbs yourself, but have
them replaced at a qualified specialist
workshop which has the necessary specialist
knowledge and tools to carry out the work
required.
Mercedes-Benz recommends that you use an
authorized Mercedes-Benz Center for this
purpose. In particular, work relevant to safety
or on safety-related systems must be carried
out at a qualified specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly. 282

Lights and windshield wipers

Never fold a windshield wiper arm without
a wiper blade back onto the windshield.
Hold
the windshield wiper arm firmly when
you change the wiper blade. If you release
the windshield wiper arm without a wiper
blade and it falls onto the windshield, the
windshield may be damaged by the force of
the impact.
Mercedes-Benz recommends that you have
the wiper blades replaced by a qualified
specialist workshop, e.g. at an authorized
Mercedes-Benz Center.
! Always position the windshield wiper
arms vertically before folding them away
from the windshield. By doing so, you will
avoid damage to the hood.

the air dehumidification function
Important information The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
G
WARNING
If you switch off the cooling function, the
vehicle will not be cooled when weather
conditions
are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a
malfunction.
You can activate or deactivate the cooling
with air dehumidification function via
COMAND (Y page 267).
i The cooling with air dehumidification
function uses refrigerant R134a. This
coolant does not contain
chlorofluorocarbons, and therefore does
not damage the ozone layer. Problems with the cooling with air
dehumidification function If you can no longer switch on the cooling with
air dehumidification function via COMAND,
the

cooling with air dehumidification function
is switched off due to a malfunction.

In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the
temperature of the dispensed air, the airflow

Automatic mode will achieve optimal
operation if cooling with air dehumidification
is also activated. If desired, cooling with air
