ing
CLK 200 CGI, CLK 55 AMG:
Super un leaded sulphur-free petrol with
am inimum octane rating of 98 RON /
88 MON.
i As a very temporary meas ure, you may
also use premium unleaded petrol, 95 RON /
85 MON. This may reduce power and increase
petrol consumption. Av oid the use of full throttle.
! The following mayle ad to increased wear or
engine damage:
! The use ofpetrol which does not com ply with
EN 228
! The useof fuel additives
The use offue lsand /orfuel addit iveswhich
have not been approved may result inlimitation
of warrant yrights. Leaded petrol
You may fill up
with leaded petrol incoun-
tries where unleaded petrol is not availa-
ble. This shortens the interval for replacing
spark pl ugs to 20,000 km.
6 Consult a Mercedes-Benz Service
Centre before using leaded petrol.
! Leaded petrol damages the catalytic con-
verter and the Lambda probe.
If you exceed theinte rval for replacing the spark
plu gs, this ma y cause increased wear and engine
damage.
You may obtain furthe rinformation from any
Mercede s-Be nz Service Centre. i
You will generally find inf ormation about the
diesel grade on the filling pump. If not, askth e
filling station attenda nt.
We recommend having the engine oil
change devery 7,500 km in countries
where only diesel fuel with a sulphur con-
tent exceeding 0.5 percent by weight is
available.
! Use of the following may lead toincreased
we ar or engine damage:
! Diesel which does not compl ywith EN 590
! Marine diesel fuel
! Heating oil
! Vegetable oil methyl ester (VOME)
! Fuel additives ("b iodiesel", FAME fue ls)
The use of fuels an d/or fuel additives which
have not bee napproved may result in limitation
of warranty right s. Diesel (EN 590)209en_d2.boo Seite

You will only be able to estimate the oil
consumption after you have driven a con-
siderable distance. i
Lubricant additives maynot be use dsince

Operation
Engine compartment
There is no need for you to check the oil
level in the autom atictransmission. In the
event of oil loss or problems with gear
shifts, have the automatic tr ansmiss ion
checked at a qualified specialist workshop,
e.g. at a Mercedes-Benz Service Centre.
Coolant is a mixture of water, antifreeze
and corrosion inhibitor. Only check the
coolant level when the vehicle is standing
on a level surface and the engine has
cooled down.
The expansion tank is located in the engine
compartment on the right-hand side when
vi ewed inthe direction of travel. 1

! when the coolant is cold, it reaches
the mark inthe expansion tank filler
neck
! when the coolant is hot, it reaches
approximately 1.5 cm higher 6
Top up the coolant in the filler neck if
necessary.

Winter driving
Have your vehicle winterproofed at a
qualified specialist workshop, e.g. at a
Mercedes-Benz Service Centre, at the on-
set of winter. This servi ceincludes the fol-
lo wi ng:
! Engine oil change,
if the current oil used has not been
approved for winter use
! The antifreeze /anti-corrosion
concentration is checked
! A concentrated cleanin gagent is
added to the windscreen and headl amp
cleaning system fluid*
! The battery is checked
! A tyre change Us
ewinter tyres at temperatures below
+7 °C and on snow or ice-covered roads.
Th e maximum effect of the ABS and ESP
dri ving systems is on lyachieved in win ter
with these tyr es.
Us ewinter tyres of the same make and
tread on all wheels to maintain safe han-
dling characteristics. Always observe the maximum permitted
speed sp
ecified for the winter tyres you
have fitted. If you fit winter tyres whi ch
have a lower maximu mpermitt ed speed
than that of the vehicle, affix an appropri-
ate warning sign in the driver's field of
vision. This ca nbe obtained at a qualified
specialist workshop, e.g. at a Mercedes-
Benz Service Centre.
In such circumstances, you should also
restrict the maximum speed of the vehicle
to the maximum permitted speed for the
winter tyres using permanent Speedtronic
( = pa ge 211). Winter dri

Risk of accident You must re
place wint ertyres with tread

These tyres are no tsuitable for use in winter
an d do not provide sufficient grip. You could
therefore lose control of the vehicle and
