G
Risk of injury
Children could injure themselves if they oper-
ate the sliding sunroof.
Never leave children unsupervised in the vehi-
cle. Always take the key with you when leaving
the vehicle, even if you are only leaving it for
a short time. G
Risk of injury
The glass in the panorama sunroof could
break in an accident. If you are not wearing a
seat belt, there is a risk that you could be
thrown through the opening in the event of the
vehicle overturning. Therefore, always wear a
seat belt to reduce the risk of injuries.
! Only open the panorama sliding sunroof
if it is free of snow and ice. Otherwise, mal-
functions may occur.
Do not allow anything to protrude from the
sliding sunroof. The seals could otherwise
be damaged.
i When the sliding sunroof is open, apart
from the normal airflow noises resonance
noises may also occur. 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.

Running-in notes
The first 1,500 km
G
Risk of accident
New brake pads/linings only have optimal
braking performance after several hundred
kilometres. Until then, compensate for this by
applying greater force to the brake pedal. This
also applies when brake pads/linings or
brake discs have been changed.
If you treat the engine with sufficient care
from the very start, you will be rewarded with
excellent performance for the remainder of
the engine's life.
R Therefore, you should drive at varying road
and engine speeds for the first 1,500 km.
R Avoid heavy loads, e.g. driving at full throt-
tle, during this time. Do not exceed 2
/ 3 of
the maximum permissible engine speed for
each gear.
R Change gear in good time.
R Do not shift down a gear manually in order
to brake.
R try to avoid depressing the accelerator
pedal beyond the pressure point (kick-
down).
R only use ranges 3,2or 1for slow driving,
e.g. in mountainous terrain.
After 1,500 km, you may gradually bring the
vehicle up to full road and engine speeds.
i These running-in instructions must also
be observed if you have the engine, the dif-
ferenial gear or the front axle differential of
your vehicle replaced. Refuelling
Refuelling
G
Risk of explosion
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Switch off the engine and the auxiliary heat-
ing* before refuelling. G
Risk of injury
Avoid any contact with fuels.
You can damage your health if your skin
comes into direct contact with fuel or if you
inhale fuel vapours. G
Risk of fire
Do not use petrol to refuel vehicles with a die-
sel engine. Never mix diesel with petrol. This
causes damage to the fuel system and engine
and could result in the vehicle catching fire.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with a petrol engine. Even a small
quantity of the wrong fuel will damage the
fuel system and engine. Damage resulting
from adding the wrong fuel is not covered
by the implied warranty.
! 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.
When you open or close the vehicle with the
key or KEYLESS GO*, the fuel filler flap is
automatically unlocked or locked.
The position of the fuel filler cap is to the rear

DIN 51628 German standard can lead to
increased wear, engine damage and dam-
age to the exhaust system.
Do not use the following:
R marine diesel
R heating oil
R bio-diesel
R vegetable oil
R petrol
R paraffin
R kerosene
Do not add such fuels to diesel fuel and do
not use any special additives (exception:
flow improvers – see "Low outside temper-
atures").
Damage caused by the use of unapproved
fuels or additives is not covered by the
implied warranty.
Further information on "Fuel" (Y page 287).
Low outside temperatures The flow properties of diesel may be inade-
quate at low ambient temperatures.
Diesel fuel with improved cold flow qualities
is available during the winter months. In
Europe, various climate-dependent low-tem-
perature classes are defined in EN 590. Using
diesel fuels which meet the climatic require-
ments set out in EN 590 can help avoid oper-
ating problems. The flow properties of diesel
fuel may be inadequate at unusually low out-
side temperatures or when using fuel which
has not been adjusted to climatic conditions
(e.g. diesel fuels from Mediterranean
regions).
Flow improver
Flow improvers may be added to improve low-
temperature resistance. The effectiveness of
a flow improver is not guaranteed with every
fuel.
Correct dosage and mixing are decisive fac-
tors in ensuring improvement in low-temper- ature resistance. Under certain circumstan-
ces, an excessive dosage may actually
decrease low-temperature resistance, and
should therefore be avoided (follow the man-
ufacturer's dosing instructions).
Mix the additive with the diesel in good time,
before the flow properties of the diesel
become inadequate. Otherwise, malfunctions
can only be rectified by heating the entire fuel
system, e.g. by parking the vehicle in a heated
garage.
Observe the information provided by the man-
ufacturer when using a flow improver. Only
use flow improvers that have been tested and
approved by Mercedes-Benz. You can obtain
further information from any Mercedes-Benz
Service Centre.
