Risk of fire and poisoning
The operation of the auxiliary heating pro-
duces hot, toxic exhaust fumes. The fuel
vapours produced during refuelling could
ignite on the hot exhaust system.
Do not switch on the auxiliary heating at
filling stations or in enclosed spaces, for
instance,

a garage, if there is no air extrac-
tion system.
You could otherwise endanger yourself and
others.

Refuelling
190 Running-in notes
The first 1,500 km
If you treat the engine with sufficient care
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.
R Try to avoid depressing the accelerator
pedal beyond the pressure point (kick-
down).
R Only use ranges 3, 2 or 1 for slow driving,
e.g. in mountainous terrain.
After 1,500 km you may gradually bring the
vehicle up to full road and engine speeds.
Additional driving tips for AMG vehicles: R
Do not drive faster than
140 km/h for the
first 1,500 km.
R Only bring the engine up to a maximum
speed of 4,500 rpm for a brief period.
i You should also observe these notes if the
engine or rear axle transmission on your
vehicle has been replaced. AMG vehicles with a rear axle differ-
ential lock*
Your vehicle is equipped with a self-locking
differential

on the rear axle. To better protect
the differential gear on the rear axle, you
should perform an oil change after a running-
in phase of 3,000 km. This oil change will
increase the service life of your differential.
Have the oil change performed at a qualified
specialist workshop. Mercedes-Benz recom-
mends that you use a Mercedes-Benz Service
Centre for this purpose. Refuelling

G
Risk of explosion
Fuel is highly flammable. Fire, naked flames
and
smoking are therefore prohibited when
handling fuels.
Before refuelling, turn off the engine and
the auxiliary heating*. 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 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. 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. Operation

!
Do not start the engine if you accidentally
refuel with the wrong fuel. Otherwise, you
risk engine damage. Consult a specialised
qualified workshop and 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 To open the fuel filler flap
2 To insert the fuel cap
3 Tyre pressure table
4 Fuel type X
To open: press the fuel filler flap in the
direction of arrow 1.
The fuel filler flap opens slightly.
X Open the fuel filler flap.
X Turn the fuel filler cap to the left and
remove it.
X Insert the fuel filler cap into the holder
bracket on the inside of filler flap 2.
X Only fill the tank until the pump nozzle
switches off.
! Overfilling the tank could damage the fuel
system.
X To close: replace the fuel filler cap and turn
it clockwise. The fuel filler cap audibly
engages.
X Close the fuel filler flap.
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 254).
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 "Fuel" in the index.
i As a temporary measure, but only when
the recommended fuel is not available, you
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 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 given on the con-
tainer.

CLS 350 CGI !
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 In some countries, only petrol of insuffi-
cient quality (high-sulphur fuel) may be
available. This fuel can temporarily produce
unpleasant odours, especially on short
journeys. Refuelling with petrol of sufficient
quality (sulphur-free fuel) will reduce such
odours.
AMG vehicles !
Refuel using only super unleaded petrol
with a minimum octane number of 98
RON/88 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
If the recommended fuel is not available
and

only as a temporary measure, you may
also use premium unleaded petrol,
95 RON/85 MON. This may reduce per-
formance and increase petrol consump-
tion. You must avoid driving at full throttle.
! In emergencies, only when the recom-
mended fuel is not available, you may also
use standard unleaded petrol, 91 RON/
82.5 MON. However, using this fuel results
in considerably higher petrol consumption
and significantly reduced performance.
Avoid driving at full throttle, and only drive
in drive program C.
If no fuel other than regular petrol fuel 91
RON/82.5 MON or a lower grade is per-
manently available, you should have the
vehicle adapted to run on this fuel by the
local after-sales service. Diesel (EN 590)
! Only use diesel that complies with the
EN 590 European standard.
You could otherwise impair engine output
or damage the engine.
You will find further information about die-
sel under "Fuel" 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
