Refuelling
192
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

Tyres and wheels
198 Tyres and wheels
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 may be adversely affected. In addition, the
wheels may come into contact with the
body
or axle components when heavily loa-
ded or when driving with snow chains. This
could result in damage to the tyres or the
vehicle.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As a result,
Mercedes-Benz cannot guarantee vehicle
safety if retreaded tyres are fitted. Do not
fit used tyres if you have no information
about their previous usage. G
Risk of accident
If wheels or tyres other than those which
have been tested are fitted:
R the
brakes or chassis components could
be damaged
R wheel and tyre clearances can no longer
be guaranteed
This could cause an accident.
Modification work on the brake system and
wheels is not permitted, nor is the use of
spacer plates or brake dust shields. This inva-
lidates the General Operating Permit for the
vehicle. Notes on selecting, fitting and replacing
tyres R
Only fit tyres and wheels of the same type
and make.
R Only fit tyres of the correct size onto the
wheels.
R After
fitting new tyres, run them in at mod-
erate speeds for the first 100 km as they
only reach their full performance after this
distance.
R Fit new tyres on the front wheels first if
tyres of the same size are required on the
front and rear wheels.
R Replace the tyres after six years at the lat-
est, regardless of wear. This also applies to
the spare wheel*.
R Do not drive with tyres which have too little
tread depth as this significantly reduces
the traction on wet roads (aquaplaning).
! Store tyres that are not being used in a
cool, dry and preferably dark place. Protect
the tyres against oil, grease, petrol and die-
sel. Operation
* optional
