Risk of injury
Various warning stickers are affixed to your
vehicle.
Their purpose is to draw your atten-
tion, and the attention of others, to various
dangers. Therefore, do not remove any
warning stickers unless the sticker clearly
states that you may do so.
If you remove the warning stickers, you or
others could be injured by failing to recog-
nise certain dangers. Introduction

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

Engine compartment
195Engine oil
Depending on how it is driven, the vehicle
consumes a maximum of 0.8 l oil per 1,000
km. The oil consumption may be higher than
this when the vehicle is new or if you fre-
quently drive at high engine speeds. You can
only estimate the oil consumption after you
have driven a considerable distance.
You will find further information about engine
oil in the "Technical data" section
(Y page 314).
Checking the engine oil level To do so:
R
the vehicle should be parked on level
ground
R the engine should be switched off for at
least five minutes if the engine was at nor-
mal operating temperature
R the engine should be switched off for at
least 30 minutes if the engine was not at
operating temperature (i.e. if you only star-
ted the engine briefly) Using the oil dipstick
Example of a vehicle with a petrol engine (CLS 350)

lamp cleaning system*
The washer fluid reservoir is located in the
engine compartment on the right when
viewed in the direction of travel. The head-
lamp cleaning system* is also supplied from
the washer fluid reservoir.1 Cover X
Add windscreen washer concentrate to the
washer fluid all year round.
G Risk of fire
Windscreen washer concentrate is highly
flammable. Fire, naked flames and smoking
are prohibited when windscreen washer
concentrate is being handled.
Use
R a windscreen washer fluid additive
such as MB Summerwash to prevent
smearing (for temperatures above freez-
ing).
R a windscreen washer fluid additive with
antifreeze properties such as MB Winter-
wash (if there is a risk of frost).
X Mix the windscreen washer fluid in a con-
tainer beforehand. Adapt the mixing ratio
to the outside temperatures.
! Only use windscreen washer fluid which
is suitable for plastic lamp lenses. Unsuit-
able windscreen washer fluid could dam-
age the plastic lamp lenses of the head-
lamps. X
To open: pull cap 1 upwards by the tab.
X To close: press cap 1 onto the filler neck
until it clicks into place.

Genuine Mercedes-Benz parts
298 Introduction to technical data
i The technical data was determined in
accordance with EU directives. All data
applies to the vehicle's standard equip-
ment. The data may therefore differ for
vehicles with optional equipment. You can
obtain further information from a
Mercedes-Benz Service Centre. Genuine Mercedes-Benz parts
Mercedes-Benz tests genuine parts and con-
version parts and accessories which have
been
specifically approved for your vehicle for
their reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benz is
unable to evaluate other parts. Mercedes-
Benz therefore accepts no responsibility for
the use of such parts in Mercedes-Benz vehi-
cles, even if they have been independently or
officially approved.
In Germany and some other countries, certain
parts are only officially approved for installa-
tion or modification if they comply with legal
requirements. All genuine Mercedes-Benz
parts meet this requirement. The use of non-
approved parts may invalidate the vehicle's
general operating permit. This is the case if:
R they cause a change of the vehicle type
from that for which the vehicle's general
operating permit was granted
R other road users could be endangered
R the emission or noise levels are adversely
affected
The use of non-approved parts could affect
your vehicle's operating safety. Mercedes-
Benz therefore recommends genuine Mercedes-Benz parts and conversion parts
and
accessories that have been approved for
your vehicle. H
Environmental note
Daimler also supplies reconditioned
assemblies
and parts which are of the same
quality as new parts and to which the same
warranty applies.
Genuine Mercedes-Benz parts and approved
conversion parts and accessories are availa-
ble from Mercedes-Benz Service Centres.
There, you can also receive advice about tech-
nical modifications and have the parts pro-
fessionally fitted.
Always quote the vehicle identification num-
ber and the engine number when ordering
genuine parts. You will find these numbers on
the vehicle data card in the Service Booklet
or on your vehicle's identification plates
(Y page 300). Technical data

Vehicle electronics
299Vehicle electronics
Tampering with the engine electron-
ics
G
Risk of accident
Only have work on the engine electronics
and related components carried out at a
qualified
specialist workshop which has the
necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
The vehicle's roadworthiness could other-
wise be affected.
! Only have work done on the engine elec-
tronics and its associated parts, such as
control units, sensors and connector leads,
carried out at a qualified specialist work-
shop, e.g. a Mercedes-Benz Service
Centre. Otherwise, vehicle components
may wear more quickly and the vehicle may
lose its liability for material defects and its
operating permit. Retrofitting electrical and electronic
equipment
Electrical

and electronic equipment can jeop-
ardise the operating safety of your vehicle. If
equipment of this kind is retrofitted, it must
be type-approved and bear the e mark. The
e mark may be obtained from the equipment
manufacturer or an authorised testing centre.
! Damage or consequential damage arising
from fitting equipment not approved
by Mercedes-Benz is not covered by the
Mercedes-Benz warranty.
If you wish to install two-way radios in the
vehicle, you must obtain formal approval.
Mercedes-Benz approves the installation of
two-way radios if such equipment is installed
professionally and a low-reflection exterior
aerial is used.
The transmission output of the two-way radio
must not exceed the maximum transmission
outputs listed. G
Risk of accident
Two-way radios may interfere with the vehi-
cle electronics and thereby jeopardise the
operational safety of the vehicle and your
own safety if: R
they do not have an exterior aerial
R the exterior aerial is not a low-reflection
aerial
R the exterior aerial has been fitted incor-
rectly G
Risk of injury
Excessive electromagnetic radiation may
also cause damage to your health and the
health of others. Using an exterior aerial
takes into account current scientific dis-
cussions

relating to the possible health haz-
ards that may result from electromagnetic
fields.
For this reason, only have the exterior aerial
fitted at a qualified specialist workshop
which has the necessary specialist knowl-
edge and tools to carry out the work
required. Mercedes-Benz recommends
that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified
specialist workshop.
i Mercedes-Benz recommends the use of
an approved exterior aerial. This ensures
optimal reception quality for mobile tele- Technical data

This also ensures that interference
between these devices and the vehicle's
electronics is kept to a minimum. If instal-
led, the exterior aerial conducts the elec-
tromagnetic fields transmitted by a mobile
phone to the exterior of the vehicle.
