Vehicle equipment
i This manual describes all the standard
and optional equipment of your vehicle
which was available at the time of
purchase. Country-specific differences are
possible. Bear in mind that your vehicle
may not feature all functions described
here. This also refers to safety-related
systems and functions.
Overview of climate control systems
Important safety guidelines
GWarning
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval. A clogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a clogged filter replaced as soon as
possible at an authorized Mercedes-Benz
Center.
GWarning
Follow the recommended settings for heating
and cooling given on the following pages.
Otherwise, the windows could fog up,
impairing visibility and endangering you and
others.
Dual-zone automatic climate control/multi-
zone automatic climate control 14
controls the
temperature and the humidity of the vehicle
interior and filters out undesirable
substances from the air.
Dual-zone automatic climate control/multi-
zone automatic climate control 14
is only
operational when the engine is running 15
.
Optimum operation is only achieved when
you drive with the side windows and tilt/
sliding sunroof/panorama roof with power
tilt/sliding panel closed.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature ( Y page 89).
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly.
i The integrated filter can filter out most
particles of dust and completely filters out
pollen. A clogged filter reduces the amount
of air supplied to the vehicle interior. For
this reason, you should always observe the
interval for replacing the filter, which is
specified in the Service Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet.14 For Canada only.
15 The "residual heat" function can only be switched on/off when the ignition is switched off.132Overview of climate control systemsClimate control

GWarning!
Do not fill diesel tanks with gasoline. Do not
mix diesel fuel with gasoline. Otherwise the
fuel system and engine could be damaged. In
addition, the vehicle could catch fire.
! Do not use gasoline to refuel vehicles with
a diesel engine. Do not use diesel to refuel
vehicles with a gasoline engine. Even small
amounts of the wrong fuel result in damage
to the fuel system and engine.
! Do not start the engine if you accidentally
refuel with the wrong fuel. Otherwise, the
fuel could enter the fuel lines. This would
require draining of the fuel tank and fuel
lines. Notify a qualified specialist workshop
and have the fuel tank and fuel lines
drained completely.
Gasoline
Fuel grade
! You should only refuel with unleaded
premium-grade gasoline as this avoids
damaging the catalytic converter.
If engine running problems are apparent,
have the cause checked immediately and
repaired. Excess unburned fuel can
otherwise enter the catalytic converter,
leading to overheating and possibly
causing a fire.
i Only refuel with unleaded premium-grade
gasoline with a specified minimum octane
number of 91 (average value of 96 RON/
86 MON).
Usually you will find information about the
fuel grade on the pump. If you cannot find
the label on the gasoline pump, ask the gas
station staff.
You can find further information under
"Fuel" ( Y page 352), by consulting an
authorized Mercedes-Benz Center or
visiting http://www.mbusa.com (USA
only).
Diesel
Fuel grade
! Only refuel with ULTRA-LOW SULFUR
DIESEL FUEL (ULSD, 15 ppm SULFUR
MAXIMUM). Using other diesel fuels could
result in increased wear and damage to the
engine and/or exhaust system.
Never refuel with marine diesel or heating
oil.
Do not mix these fuels with diesel fuels and
do not use any special additives, as this
may result in damage.
! When refueling using a fuel can, use a
filter or use a clean cloth as a filter.
Otherwise, particles from the fuel can may
block the fuel lines and/or the diesel
injection system.
i Refuel only with ULTRA-LOW SULFUR
DIESEL FUEL (ULSD, 15 ppm SULFUR
MAXIMUM).
Usually you will find information about the
fuel grade on the pump. If you cannot find
the label on the gasoline pump, ask the gas
station staff.
You can find further information under
"Fuel" ( Y page 352), by consulting an
authorized Mercedes-Benz Center or by
visiting http://www.mbusa.com (USA
only).
Low outside temperatures
! Do not use gasoline to refuel vehicles with
a diesel engine. Never mix diesel with
gasoline or kerosene, as this may result in
damage to the engine or fuel system.
Diesel fuel with improved cold flow properties
is available during the winter months. Further
information on fuel properties can be
obtained from oil companies, e.g. at gas
stations.

! Only use AdBlue ®
that complies with
ISO 22241. Do not add any special
additives to AdBlue ®
and do not thin
AdBlue ®
with water. This could destroy the
BlueTEC exhaust gas aftertreatment.
! Rinse surfaces that have come into
contact with AdBlue ®
immediately with
water or remove AdBlue ®
using a damp
cloth and cold water. If the AdBlue ®
has
already crystallized, use a sponge and cold
water to clean it. AdBlue ®
residues
crystallize after time and contaminate the
affected surfaces.
High outside temperatures
If AdBlue ®
is heated to above 122 ‡ (50 †)
for an extended period of time, e.g. due to
direct sunlight on the AdBlue ®
tank,
AdBlue ®
may start to decompose. Ammonia
vapors develop as a result.
GWarning!
When opening the filler cap of the AdBlue ®
tank ammonia gas vapors may escape. Refill
AdBlue ®
in a well ventilated area only.
Ammonia gas vapors have a pungent odor and
are particularly irritating for your skin,
mucous membranes, and eyes. Inhaling
ammonia gas vapors will cause burning eyes,
nose, and throat, as well as coughing and
watering eyes.
Low outside temperatures
AdBlue ®
freezes at a temperature of
approximately 12 ‡ (-11 †). The vehicle is
equipped with an AdBlue ®
preheating system
at the factory. Winter operation can thus be
guaranteed even at temperatures below
12 ‡ (-11 †).
Additives
! Use only AdBlue ®
complying with ISO
22241. Do not use any additives with
AdBlue ®
and do not thin AdBlue ®
with
water. This may destroy the BlueTEC
exhaust gas aftertreatment system.
Damage resulting from the use of additives
or water is not covered by the Mercedes-
Benz Limited Warranty.
Purity
Assuring the purity of AdBlue ®
is particularly
important with respect to avoiding
malfunctions in the exhaust gas
aftertreatment system.
If AdBlue ®
is pumped out of the AdBlue ®
tank,
e.g. during repair work, it must not be
returned to the tank. The purity of the fluid
can no longer be guaranteed.
! Impurities in AdBlue ®
, e.g. due to other
service products, cleaning agents or dust,
lead to increased emission values, system
malfunctions, catalytic converter damage
or damage to the BlueTEC system.
Engine oil
Points to remember
The engine oils are matched to the
performance of our engines and service
intervals. For this reason, only use engine oils
and oil filters that are approved for vehicles
with a service system.
Contact an authorized Mercedes-Benz Center
or visit http://www.mbusa.com (USA only)
for a list of approved engine oils and oil filters.
! Never use engine oil or an oil filter of a
specification other than is necessary to
fulfill the prescribed service intervals. Do
not change the engine oil or oil filter in
order to achieve longer replacement
intervals than those prescribed. Otherwise,
you may cause damage to the engine or
exhaust gas aftertreatment; this is not
covered by the Mercedes-Benz Limited
Warranty.
Follow the instructions in the service
interval display regarding the oil change.
