Problems with the seat heating
Problem
Possible causes/consequences and
M
MSolutions The seat heating has
switched off prema-
turely or cannot be
switched on. The on-board voltage is too low because too many electrical con-
sumers are switched on.
X Switch off electrical consumers that you do not need, such as
the rear window heating or interior lighting.
Once the battery is sufficiently charged, the seat heating can be
switched back on manually. Switching the seat ventilation on/off
Switching on/off The three blue indicator lamps in the buttons
indicate the ventilation level you have selec-
ted.
X Turn the key to position 1or 2in the ignition
lock (Y page 187).
X To switch on: press button:repeatedly
until the desired ventilation level is set.
X To switch off: press button:repeatedly
until all the indicator lamps go out.
i If the battery voltage is too low, the seat
ventilation may switch off.
i You can open the side windows and the
sliding sunroof using the convenience
opening feature (Y page 111). The seat
ventilation of the driver's seat automati-
cally switches to the highest level.
i When the vehicle is stationary, the fan
speed can be reduced automatically. This
reduces the noises of the seat ventilation. Seats

only the turn signal lamp on the corre-
sponding side of the vehicle will flash.
X To switch off the hazard warning lamps:
press button :.
The hazard warning lamps switch on auto-
matically if:
R an airbag is deployed or
R the vehicle decelerates rapidly from a
speed of above 70 km/h and comes to a
standstill
The hazard warning lamps switch off auto-
matically if the vehicle reaches a speed of
above 10 km/h again after a full brake appli- cation.
The hazard warning lamps continue to oper-
ate even if the ignition is switched off. Intelligent Light System
General notes The Intelligent Light System is a system that
adjusts the headlamps automatically to suit
the prevailing driving and weather conditions. It offers advanced functions for improved illu-
mination of the road surface, e.g. depending
on the vehicle speed or weather conditions.
The system includes the active light function, cornering light function, motorway mode,
extended range foglamps and off-road lights.
The system is only active when it is dark.
You can activate or deactivate the "Intelligent Light System" function using the on-board
computer (Y page 331). Exterior lighting

Important safety notes G
DANGER
If the exhaust pipe is blocked or sufficient
ventilation is not possible, toxic exhaust
fumes can enter the vehicle, especially car-
bon monoxide. This is the case, e.g. in
enclosed spaces, or if the vehicle is stuck in
snow. There is a risk of fatal injuries.
You should switch off the auxiliary heating in
enclosed spaces which do not have an extrac- tion system, e.g. a garage. If the vehicle is
stuck in snow and you must leave the auxiliary
heating running, keep the exhaust pipe and
the area around the vehicle clear of snow. To guarantee a sufficient supply of fresh air, open
a window on the side of the vehicle away from the wind. G
WARNING
When the auxiliary heating is switched on,
parts of the vehicle can become very hot.
Flammable materials such as leaves, grass or twigs may ignite if they come into contact
with:
R hot parts of the exhaust system
R the exhaust gas itself
There is a risk of fire. When the auxiliary heating is switched on,
make sure that:
R no flammable materials come into contact
with hot vehicle components
R the exhaust gas can escape from the
exhaust pipe unhindered
R the exhaust gas does not come into contact
with flammable materials.
The auxiliary heating is fitted under the front
wing on the right-hand side of the vehicle. The emissions outlet is found behind the front
wheel on the right-hand side of the vehicle.
! Operating the auxiliary heating/ventila-
tion draws on the vehicle battery. After you have heated or ventilated the vehicle a
maximum of two times, drive for a longer
distance.
Switch the auxiliary heating on regularly once a month for about ten minutes.
The auxiliary heating heats the air in the vehi-
cle interior to the set temperature. This
occurs without using the heat of the running
engine. The auxiliary heating is operated
directly using the vehicle's fuel. For this rea-
son, the tank content must be at least at
reserve fuel level to ensure that the auxiliary
heating functions.
The auxiliary heating or auxiliary ventilation
automatically adjusts to changes in temper-
ature and weather conditions. For this rea-
son, the auxiliary heating could switch from
ventilation mode to heating mode or from
heating mode to ventilation mode.
The auxiliary heating switches off when the
engine is switched off. The auxiliary ventila-
tion is not active if the engine is running.
The auxiliary heating or auxiliary ventilation
switches off automatically after 50 minutes.
This time limit can be altered. To do this, visit a qualified specialist workshop.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature. 178

Before driving your vehicle outside Europe,
have the AdBlue ®
supply checked at a quali-
fied specialist workshop.
Further information about BlueTEC exhaust
gas aftertreatment and about AdBlue ®
can
be obtained from any Mercedes-Benz Service Centre. Important safety notes AdBlue
®
is a water-soluble fluid for the
exhaust gas aftertreatment of diesel engines.
It is:
R non-toxic
R colourless and odourless
R non-flammable
If you open the AdBlue ®
tank, small amounts
of ammonia vapour may be released.
Ammonia vapours have a pungent odour and
are particularly irritating to the skin, to
mucous membranes and to the eyes. You may experience a burning sensation in your eyes,
nose and throat. You may also experience
coughing and watery eyes.
Do not inhale any ammonia vapours that may
be released. Only fill the AdBlue ®
tank in well-
ventilated areas.
Do not swallow AdBlue ®
or let it come into
contact with skin, eyes or clothing. Keep
AdBlue ®
away from children.
If you or others come into contact with
AdBlue ®
, observe the following:
R immediately rinse AdBlue ®
off your skin
with soap and water.
R if AdBlue ®
comes into contact with your
eyes, immediately rinse them thoroughly
with clean water. Seek medical attention
immediately.
R if AdBlue ®
is swallowed, immediately rinse
your mouth out thoroughly. Drink plenty of water. Seek medical attention immedi-
ately.
R change immediately out of clothing that
has come into contact with AdBlue ®
.
! Only use AdBlue ®
in accordance with
ISO 22241. Do not mix any additives with
AdBlue ®
, and do not dilute AdBlue ®
with
water. This may destroy the BlueTEC
exhaust gas aftertreatment system.
! In order to fill the AdBlue ®
tank, the vehi-
cle must be parked on a level surface. The
AdBlue ®
tank can only be filled as intended Refuelling
207Driving and pa rking Z

with the vehicle parked on a level surface.
Fluctuations in capacity will thus be avoi-
ded. Filling a vehicle standing on an uneven surface is not permitted. There is a danger
of overfilling, which can cause damage to
BlueTEC exhaust gas aftertreatment com-
ponents.
! Surfaces which have come into contact
with AdBlue ®
while refilling should be
rinsed immediately with water, or remove
AdBlue ®
with a moist cloth and cold water.
If AdBlue ®
has already crystallised, use a
sponge and cold water to clean the area.
AdBlue ®
residue crystallises after a certain
amount of time and soils the affected sur-
faces.
! AdBlue ®
is not a fuel additive and must
not be added to the fuel tank. If AdBlue ®
is
added to the fuel tank, this can lead to
engine damage.
Have the AdBlue ®
tank refilled at a qualified
specialist workshop. However, you can also
top up the AdBlue ®
tank:
R at a filling station with an AdBlue ®
filling
pump
R with AdBlue ®
refill bottles
R with an AdBlue ®
refill canister
When the pump nozzle switches off automat- ically during filling at a filling pump, the
AdBlue ®
tank has been completely filled. Do
not fill the AdBlue ®
tank any further. AdBlue ®
may leak out.
To avoid transporting already opened refill
containers in the vehicle, completely empty
refill bottles or canisters when filling the
AdBlue ®
tank, if possible.
