To avoid damage to the seats and the seat
heating, observe the following information:
R keep liquids from spilling on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
R if the seat covers are damp or wet, do not
switch on the seat heating. The seat
heating should also not be used to dry
the seats.
R clean the seat covers as recommended;
see "Interior care".
R do not transport heavy loads on the
seats. Do not place sharp objects on the
seat cushions, e.g. knives, nails or tools.
The seats should only be occupied by
passengers, if possible.
R when the seat heating is in operation, do
not cover the seats with insulating
materials, e.g. blankets, coats, bags,
seat covers, child seats or booster seats.
! Make sure that there are no objects in the
footwell or behind the seats when resetting
the seats. There is a risk that the seats
and/or the objects could be damaged.
i The head restraints in the front seats are
installed with the NECK-PRO system
(Y page 55). For this reason, it is not
possible to remove the head restraints
from the front seats.

WARNING
If head restraints are not installed and
adjusted correctly, they cannot provide
protection as intended. There is an increased
risk of injury in the head and neck area, e.g.
in the event of an accident or when braking.
Always drive with the head restraints
installed. Before driving off, make sure for
every vehicle occupant that the center of the
head restraint supports the back of the head
at about eye level.
General notes Observe the important safety notes regarding
the seats (Y page 117).

Problems with the seat ventilation
Problem Possible causes/consequences and
0001 Solutions
The seat ventilation has
switched off
prematurely or cannot
be switched on. The on-board voltage is too low because too many electrical
consumers are switched on.
X
Switch off electrical consumers that you do not need, such as
the rear window defroster or interior lighting.
Once the battery is sufficiently charged, the seat ventilation will
switch back on automatically. AIRSCARF (Cabriolet)

WARNING
When AIRSCARF is switched on, very hot air
can flow from the vents in the head restraints.
This could result in burns in the immediate
vicinity of the air vents. There is a risk of injury.
Reduce the heater output before it becomes
too hot. Driver's and front-passenger seat
The AIRSCARF function warms the head and
neck area of vehicle occupants with warm air.

models and all standard and optional
equipment of your vehicle available at the

General notes
For reasons of safety, Mercedes-Benz
recommends that you drive with the lights
switched on even during the daytime.
Therefore, your vehicle is equipped with
special daytime running lamps. In some
countries, operation of the headlamps varies
due to legal requirements and self-imposed
obligations.
If you wish to drive during the daytime without
lights, switch off the daytime running lamps
function in the on-board computer
(Y page 244). Driving abroad
Symmetrical low-beam headlamps Switch the headlamps to symmetrical low
beam in countries in which traffic drives on
the opposite side of the road from the country
where the vehicle is registered. This prevents
glare to oncoming traffic. When using
symmetrical lights, the edge of the road is not
lit as widely and as far ahead as normal.
Have the headlamps converted at a qualified
specialist workshop as close to the border as
possible before driving in these countries. Asymmetrical low beam Have the headlamps converted back to
asymmetrical low-beam headlamps at a
qualified specialist workshop as soon as
possible after crossing the border again.

Important safety notes
G
WARNING
Bulbs, lamps and connectors can get very hot
when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before
changing a bulb.
Vehicles with static LED headlamps:
Do not use a bulb that has been dropped or if
its glass tube has been scratched.
The bulb may explode if:
R you touch it
R it is hot
R you drop it
R you scratch it
Only operate bulbs in enclosed lamps
designed for that purpose. Only install spare
bulbs of the same type and the specified
voltage.
Marks on the glass tube reduce the service
life of the bulbs. Do not touch the glass tube
with your bare hands. If necessary, clean the
glass tube when cold with alcohol or spirit and
rub it off with a lint-free cloth.
Protec tbulbs from moisture during
operation .Do not allow bulbs to come into
contact with liquids.
Replace only the bulbs listed (Y page 143).

Clean the windshield using washer fluid
after washing the vehicle in an automatic
car wash.
! Intermittent wiping with rain sensor: due
to optical influences and the windshield
becoming dirty in dry weather conditions,
the windshield wipers may be activated
inadvertently. This could then damage the
windshield wiper blades or scratch the
windshield.
For this reason, you should always switch
off the windshield wipers in dry weather. Combination switch

In the 0001or0002 position, the appropriate
wiping frequency is set automatically
according to the intensity of the rain. In
the 0002 position, the rain sensor is more
sensitive than in the 0001position, causing
the windshield wipers to wipe more
frequently. If the wiper blades are worn, the windshield
will no longer be wiped properly. This could
prevent you from observing the traffic
conditions. Replace the wiper blades twice a
year, ideally in spring and fall.
Replacing the wiper blades
Important safety notes G
WARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could
be trapped by the wiper arm. There is a risk
of injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
! To avoid damaging the wiper blades,
make sure that you touch only the wiper
arm of the wiper.
! Never open the hood if a windshield wiper
arm has been folded away from the
windshield.
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 changed at aqualified
specialist workshop.

i Read the information on qualified
specialist workshops: (Y page 25).Overview of climate control systems
Important safety notes
Observe the settings recommended on the
following pages. The windows could
otherwise fog up.
To preven tthe windows from fogging up:
R switch off climate control only briefly
R switch on air-recirculation mode only
briefly
R switch on the cooling with air
dehumidification function
R switch on the defrost windshield function
briefly, if required
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control can only be operated when
the engine is running. Optimum operation is
only achieved with the side windows and roof
closed.
The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 158).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature (Y page 96).
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly. i
The integrated filter filters out most
particles of dust and soot and completely
filters out pollen. It also reduces gaseous
pollutants and odors. Aclogged filter
reduces the amoun tofair supplied to the
vehicle interior .For this reason, you should
always observe the interval for replacing
the filter, which is specified in the
Maintenance Booklet .As it depends on
environmental conditions, e.g. heavy air
pollution, the interval may be shorter than
stated in the Maintenance Booklet.
i It is possible that the residual heat
function may be activated automatically an
hour after the SmartKey is removed. The
vehicle is then ventilated for 30 minutes to
dry the automatic climate control. 148
