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 can continuously
increase the engine speed and bring the vehi-
cle up to full road speed.
i You should also observe these notes on
running in if the engine or the axle gear on
your vehicle has been 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 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
injection system. Damage resulting from
adding the wrong fuel is not covered by the
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, the fuel filler flap is automatically
unlocked or locked.
The position of the fuel filler cap is to the rear
on the right. The position of the fuel filler cap
is displayed in the instrument cluster 8.144 RefuellingOperation

X Close the fuel filler flap.
i Vehicles with a diesel engine: if the fuel
tank has been run completely dry, it will be
necessary to bleed the fuel system
(Y page 206). 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.
Otherwise, you could impair engine output
or damage the engine.
i As a temporary measure, only when the
recommended fuel is not available, you
may also use regular unleaded petrol,
91 RON/82.5 MON. This may reduce
engine performance and increase fuel con-
sumption. Avoid driving at full throttle.
In some countries, the quality of the avail-
able petrol may not be adequate and could
cause coking around the inlet valve. In such
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 specified on the
container.

G
Risk of fire
Do not use petrol to refuel vehicles with a die-
sel engine. Never mix diesel with petrol. This
would damage the fuel system and engine and
could result in a vehicle fire.
! Refuel using only diesel which conforms
to European standard EN 590 or German
standard DIN 51628.
Otherwise, you could impair engine output
or damage the engine.
! When refuelling vehicles with a diesel par-
ticulate filter in countries outside the EU,
only low-sulphur Euro diesel with less than
0.005 percent sulphur content by weight
(50 ppm) should be used. Refuelling

(Y page 144).
Notes on fuel consumption The vehicle will use more fuel than usual in
the following situations:
R at very low temperatures
R in urban traffic
R on short trips
R when towing a trailer
R in mountainous terrain
The consumption figures have been deter-
mined in accordance with EU Directive
RL 80 /1268 /EEC.
i Only for certain countries: the respective
current consumption and emission values
of your vehicle can be found in the COC
papers (EC CERTIFICATE OF CONFORM-
ITY). These documents are supplied when
the vehicle is delivered.
! Do not use any special additives, as they
can cause malfunctions and engine dam-
age. Damage resulting from the use of such
additives is not covered by the Mercedes-
Benz warranty. H
Environmental note
CO 2(carbon dioxide) is the gas which scien-
tists believe to be principally responsible for global warming (the greenhouse effect). Your
vehicle's CO
2emissions are directly related
to fuel consumption and therefore depend on:
R efficient use of the fuel by the engine
R driving style
R other non-technical factors, such as envi-
ronmental influences or road conditions
You can minimise your vehicle's CO 2emis-
sions by driving carefully and having it serv-
iced regularly. Engine oil
Only Mercedes-Benz approved engine oils
may be used in Mercedes-Benz engines.
A list of the engine oils tested and approved
in accordance with the Mercedes-Benz Spec-
ifications for Service Products can be called
up by visiting http:\\bevo.daimler.co m and
en tering the MB Sheet number. Further infor-
mation on tested and approved engine oils
can be obtained from any Mercedes-Benz
Service Centre. Engine oils which have been
approved by Mercedes-Benz have the MB
Sheet number indicated on the oil container
