2010 MERCEDES-BENZ SLS COUPE service

Towing the vehicle with the rear axle
raised !
The engine must be switched off (key in
ignition lock in position 0or position 1) if
the vehicle is being towed with the front
axle raised or if the parking brake is being
tested on a dynamometer. Otherwise,
intervention by ESP ®
could damage the
brake system.
Towing the vehicle with atow rope or
tow bar G
Ris
kofa ccident
If the brake system is malfunctioning, you
must use a rigid tow bar to tow the vehicle.
Before towing away, mak esure that the steer-
ing can be moved and is not locked.
If there is a malfunctio ninthe power supply
or the vehicle's electrical system, you must
not tow the vehicle. G
Risk of accident
The following can occur if the vehicle is towed:
R the engine may not start.
R the on-board electronics may fail.
R the battery voltage may drop too much.
In these cases, the rear axle will be locked.
As a result, you might lose control of the vehi-
cle, cause an accident and injure yourself and
others.
! Use the key instead of the Start/Stop
button when towing the vehicle.
Start the engine and keep it running. Turn
the key to position 2in the ignition. Set the
transmission selector lever to N.Make sure
that you then leave the key in position 2.
Chec kthe transmission position in the
instrument cluster. When towing the vehicle, proceed as follows:
X
Insert the key into the ignition lock
(Y page 203).
X Start the engine and leave the key in the
ignition.
X Move the transmission selector lever to N.
X Check the transmission position in the
instrumentc luster display (Y page 227).
X Leave the engine running during the entire
towing procedure.
Also observe the following notes:
R When towing, observe the legal require-
ments in all countries concerned.
R If the engine does not start, try jump-start-
ing it (Y page 338). Tow-starting the vehicle
is not permitted.
R If it is not possible to jump-star tthe vehicle,
have it transported to the nearest qualified
specialist workshop, e.g. aMercedes-Benz
Service Centre.
R If the transmission has been damaged,
have the vehicle transported to the nearest
qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre. Observe
the display messages in the instrument
cluster.
R If you are towing the vehicle over a longer
distance, this must be done with the rear
axle raised.
! Make sure that the electric parking brake
is released. If the electric parking brake is
faulty, visit a qualified specialist workshop.
Mercedes-Benzr ecommends that you use
a Mercedes-Benz Service Centre.
! When towing, pull away slowly and
smoothly. If the tractive power is too high,
the vehicles could be damaged.
! Only secure the tow cable or towing bar
to the towing eyes. You could otherwise
damage the vehicle.
! Do not use the towing eye for recovery,
as this could damage the vehicle. If in
doubt, recover the vehicle with a crane. 340

Fuses
Notes on changing fuses
The fuses in your vehicle serve to close down
faulty circuits. If afuse blows, all the compo-
nents on the circuit and their functions will
fail.
Blown fuses must be replace dwith fuses of
the same rating, which you can recognise by
the colour and value. The fuse ratings are lis-
ted in the fuse allocation chart. AMercedes-
BenzS ervice Centre will be happy to advise
you. G
Risk of fire
Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the
correct fuse rating for the systems con-
cerned. Do not attempt to repair or bridge
faulty fuses. Otherwise, a circuit overload
could cause a fire. Have the cause traced and
rectified at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
! Only use fuses that have been approved
for Mercedes-Benzv ehicles and which
have the correct fuse rating for the system
concerned. Otherwise, components or sys-
tems could be damaged.
The fuses are in the fuse boxes in the front-
passenger footwell and in the rear compart-
ment.
Fuse allocation chart The "Relay and fuse information sheet" is
located with the wheel-changing tools
(Y page 288) in the boot. Before changing a fuse

Notes on the technical data
i The technical data was determined in
accordance with EC Directives. All data
applies to the vehicle's standard equip-
ment. Therefore, the data may differ for
vehicles with optional equipment. You can
obtain further information from a
Mercedes-Benz Service Centre.
You can find technical data on the Internet at:
http://www.mercedes-benz.com 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, eve nifthey 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. Therefore,
Mercedes-Ben zrecommends genuine
Mercedes-Benz parts and conversion parts
and accessories that have been approved for
your vehicle. H
Environmental note
Daimler also supplies reconditioned assem-
blies and parts which are of the same quality
as new parts. For these, the same warranty
applies as for new parts.
Genuine Mercedes-Benzp artsa nd approved
conversion parts and accessories are availa-
ble from Mercedes-Benz Service Centres.
There, you can also receive advice abou tper-
mitted technical modifications and have the
parts professionally fitted.
Always specify the vehicle identification num-
ber and engine number when ordering genu-
ine Mercedes-Benzp arts. You will find these
numbers on the vehicle identification plates
on your vehicle, for example ( Ypage 348). Vehicle electronics

Ris
kofa ccident
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 recom-
mends that you use a Mercedes-Ben zService
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop. Otherwise, the vehicle's
roadworthiness could 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 your vehicle's
warranty and operating permit may be inva-
lidated. 346

implementation regulation
when retrofitting RF (radio frequency) trans-
mitters.
If your vehicle has fittings for two-way radio
equipment (e.g. taxis, hire cars or official vehi-
cles), use the power supply or aerial connec-
tions intended for use with the basic wiring.
Be sure to observe the manufacturer's addi-
tional instructions when installing the fittings.
! The Mercedes-Benz warranty does not
cove rconsequential damage resulting from
improper installation.
To ensure proper installation, Mercedes-
Benz recommends having this work done
at a Mercedes-Benz Service Centre or at
another qualified specialist workshop.

The consumption figures have been deter-
mined in accordance with EU Directive
715/1268/EC and do not refer to a specific
vehicle. Deviations from these values may
occur under normal operating conditions.
i Only for certain countries: the respective
curren tconsumption 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 implied 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.
Al ist of the engine oils tested and approved
in accordance with the Mercedes-Ben zSpec-
ifications for Service Products can be called
up by visiting http://bevo.daimler.com and
entering 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 under the "MB approval" notice. The table
shows which MB Sheet number applies to
which engine: MB Sheet number
229.5
i
In rare cases the following characteristics
of the engine oil used may be unavailable:
R engine oil brand
R grade (MB Sheet number)
R SAEc lassification (viscosity)
In such cases, you can use another mineral
or synthetic engine oil which has been
approved by Mercedes-Benz.
You must the nhave an oil change carried
out at the earliest possible opportunity.
Mixing oils reduces the benefits of high-
grade engine oil.
! Do no tuse lubricant additives. These can
lead to increased wear and damage to
mechanical assemblies. The use of lubri-
cant additives will result in a restriction of
your warranty.
Engine oil viscosity Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity,
this means that it is thick; a low viscosity
means that it is thin.
Select the SAE classification (viscosity) of the
engine oil according to the outside tempera-
ture. The following table shows you the vis-
cosity classes to be used depending on the
average air temperature. 350

Coolant
The coolan tis a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
i When the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion.
! Only top up with coolant that has been
premixed with the desired antifreeze pro-
tection. You could otherwise damage the
engine.
Further information on coolants and on fill-
ing can be found in the Mercedes-Benz
Specifications for Service Products, MB
Approval 310.1, e.g. on the Internet at
http://bevo.daimler.com. You can also
consult a Mercedes-Benz Service Centre.
! Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
the boiling point will be too low.
If antifreeze/corrosion inhibitor is present in
the correct concentration, the boiling point of
the coolant will be around 130 †. The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
R
be at least 50%. This will protect the engine
cooling system against freezing down to
around -37 †.
R not exceed 55% (antifreeze protection
down to -45 †); otherwise, heat will not be
dissipated as effectively.
If the vehicle has lost coolant, top it up with
equal amounts of water and antifreeze/cor-
rosion inhibitor. Mercedes-Benz recom-
mends an antifreeze/corrosion inhibitor
which has been approved for Mercedes-Benz.
! The engine cooling system is filled with
coolant which must be renewed after 15
years, or after 250,000 km at the latest.
The warranty is only valid if you top up with
an antifreeze/corrosion inhibitor which
has been approved by Mercedes-Benz and
if the recommended mixture ratio is
observed. Brake fluid
Over a period of time, the brake fluid absorbs
moisture from the air; this lowers its boiling
point. G
Risk of accident
If the boiling point of the brake fluid is too low,
vapour pockets may form in the brake system
when the brakes are applied hard (e.g. when
driving downhill).T his would impair braking
efficiency.
Have the brake fluid renewed every two years
with brake fluid that has been approved by
Mercedes-Benz
i There is usually a notice in the engine
compartmentt o remind you when the next
brake fluid change is due. Service products and capacities
