4 The first 1,500 km
If you treat the engine with sufficient car e
from the very start, it will reward you with
excellent performance for a very long period
afterwards .
R You should therefore 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.
Vehicles with automatic transmission* :
R Try to avoid depressing the accelerator
pedal beyond the pressure point (kick -
down).
R Only use ranges 3,2 or 1for slow driving,
e.g. in mountainous terrain. Refuellin

Risk of explosion
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Switch off the engine 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 yo u
inhale the vapour. G
Risk of fire
Do not use petrol to refuel vehicles with a
diesel engine. Never mix diesel with petrol.
This would damage the fuel system and
engine and could result in a vehicle fire.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with a petrol engine. Never mix
diesel with petrol. Even small amounts of
the wrong fuel will damage the injection
system. Damage resulting from adding the
wrong fuel is not covered by the warranty. !
Do not start the engine if you accidentally
refuelled with the wrong fuel. Otherwise
you risk engine damage. Have the fuel sys-
tem emptied completely.
When you open or close the vehicle with the
key or KEYLESS GO*, the fuel filler flap is
automatically unlocked or locked.
The fuel filler flap is to the rear on the right . 1

i Vehicles with a diesel engine:
If you have run the tank completely dry, it
will be necessary to bleed the fuel system
( Y page 289). Petrol (EN 228)
! Refuel using only unleaded premium
grade petrol with a minimum octane num-
ber of 95 RON/85 MON conforming to
European standard EN 228 .
You could otherwise impair engine output
or damage the engine.
You will find further information about pet-
rol under "Technical data" in the index .
i As a temporary measure, only when the
recommended fuel is not available, yo u
may also use regular unleaded petrol,
91 RON/82.5 MON. This may reduce per-
formance and increase petrol consump-
tion. Avoid driving at full throttle.
In some countries, the available petrol qual-
ity may not be sufficient and could caus e
coking around the inlet valve. In thes e
cases, and in consultation with a
Mercedes-Benz Service Centre, the petrol
may be mixed with the additive recommen-
ded by Mercedes-Benz (part no.
A000989254510). You must observe the
notes and mixing ratios given on the con -
tainer. Diesel (EN 590)
! Only use diesel that complies with the
EN 590 European standard.
You could otherwise impair engine outpu t
or damage the engine.
You will find further information about die-
sel under "Technical data" in the index.
! When refuelling vehicles with a diesel par-
ticle filter in countries outside the EU, only
low-sulphur Euro diesel with less than
0.005 percent sulphur content by weight
should be used. In countries in which diesel
with a higher sulphur content is available
(e.g. 0.035 percent by weight), the engine
oil should be renewed at more frequent
intervals. More information about intervals
for changing the engine oil can be obtained
from any Mercedes-Benz Service Centre.
! Using fuel that does not comply with EN
590 can increase wear and damage the
engine and the exhaust system. Do not use
the following:
R Marine diesel
R Heating oil
R Bio-diesel Operation

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 war-
ranty.
Low outside temperatures The flow properties of diesel may be insuffi-
cient at low ambient temperatures.
To prevent operating problems, diesel fuel
with improved cold flow qualities is available
during the winter months. Your vehicle must
be refuelled with this winter diesel at temper-
atures of -5 °C or below.
You can use this winter diesel at tempera-
tures down to about -20 °C without problems.
If only summer diesel fuel or less cold-resist-
ant winter diesel fuel (e.g. in Mediterranean
regions) is available, you should add an
amount of flow improver to the fuel corre-
sponding to the outside temperature. Mix the additive with the diesel in good time,
before the flow properties of the diesel
become insufficient. Otherwise, malfunctions
can only be rectified by heating the entire fuel
system, e.g. by parking the vehicle in a heated
garage. G
Risk of fire
Do not use petrol to refuel vehicles with a
diesel engine. Never mix diesel with petrol.
This would damage the fuel system and
engine and could result in a vehicle fire.
Flow improver
The effectiveness of a flow improver is not
guaranteed with every fuel. Observe the infor -
mation provided by the manufacturer when
using a flow improver. Only use flow improv-
ers that have been tested and approved by
Mercedes-Benz. Information about flow
improvers that have been tested and
approved by Mercedes-Benz can be obtained
from any Mercedes-Benz Service Centre. Engine compartment

Points to remember
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres and
wheels which have been approved by
Mercedes-Benz specifically for your vehi-
cle. These tyres have been specially adap-
ted for use with the control systems, such
as ABS or ESP, and are marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Extended
(with run-flat characteristics)
Mercedes-Benz Original Extended tyres
should only be used on wheels that have
been specifically approved by Mercedes-
Benz.
If you use other tyres and wheels,
Mercedes-Benz cannot accept any respon-
sibility for damage that may result from
this. Further information about tyres,
wheels and approved combinations can be
obtained from any Mercedes-Benz Service
Centre.
If you use tyres other than those tested and
recommended for Mercedes-Benz vehi-
cles, characteristics such as handling, vehi-
cle noise emissions and fuel consumption Operation

3 depth and the condition of the tread
across the entire width of all tyres. If nec
-
essary, turn the steering wheel so that
you can see the tyre tread more easily.
You could otherwise lose control of the
vehicle and cause an accident due to the
reduced grip of the tyres on the road. Tyre pressures
G
Risk of accident
Tyre pressure that is either too high or too
low has a negative effect on the vehicle’ s
active safety, which could lead you to caus e
an accident. You should therefore regularly
check the pressure of all your tyres (includ -
ing the spare tyre*), particularly prior to
long trips, and correct the pressure as nec -
essary.
To test tyre pressure, use a suitable pressure
gauge. The outer appearance of a tyre does
not permit any reliable conclusion about the
tyre pressure.
If the vehicle is to be heavily laden or driven
at high speeds, the tyre pressure must be
adapted according to the specifications given
in the fuel filler flap (Y page 204). Use the highest specified tyre pressure for
the spare wheel*
. G
Risk of accident
Should the tyre pressure drop repeatedly:
R Check the tyre for foreign bodies.
R Check whether the wheel is losing air or
the valve is leaking .
Tyre pressure that is too low has a negative
effect on the vehicle’s active safety, which
could lead to your causing an accident .
Tyre pressure changes by approximately
0.1 bar for every 10 °C change in ambient
temperature.
If you measure the tyre pressure in enclosed
spaces where the temperature differs from
the outside temperature, you will have to cor-
rect the measured value accordingly.
When the vehicle is driven, the tyre tempera-
ture, and with it the tyre pressure, will
increase depending on the road speed and
the load on the tyres.
Therefore, you should only correct tyre pres-
sures when the tyres are cold.
The pressure of warm tyres should only be
corrected if it is too low for the current oper-
ating conditions. You will find a table of tyre pressures for var-
ious operating conditions on the inside of
your vehicle's fuel filler flap.
Driving with tyre pressure that is too high or
too low can:
R
shorten the service life of the tyres
R cause increased tyre damag e
R have a negative effect on handling charac-
teristics (e.g. by causing aquaplaning)
i The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics .
You can, however, also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle.
Also check the tyre pressure of the spare
wheel* . H
Environmental not
e
Check the tyre pressure regularly, and at
least every 14 days. Operation
