Towing and tow-starting
331
R
Tow-starting the vehicle is not permitted.
R Vehicles with 4MATIC *must not be towed
with the front or rear axle raised.
R If the engine does not start, try jump-start-
ing it (Y page 329).
R If it is not possible to jump-start the vehicle,
have it towed to the nearest qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
R If the vehicle has suffered transmission
damage, have it carried away on a trans-
porter or trailer.
R If you are towing the vehicle, move the
automatic transmission selector lever to
N and turn the key to position 2
(Y page 76) in the ignition lock.
R Before towing the vehicle, make sure that
the battery is connected and charged. Oth-
erwise:
- you cannot switch on the ignition
- you cannot move the selector lever to N
- you have no support when braking
i Before towing the vehicle, deactivate tow-
away protection* (Y page 64)and the auto-
matic door locking feature (Y page 134).You could otherwise be locked out when
pushing or towing the vehicle. Fitting the towing eye

Fuses
333
In the event of damage to the front axle Have the propeller shaft between the rear
axle and the transfer case removed.
Have the vehicle towed with the front axle
raised.
In the event of rear axle damage (Vehi-
cles with 4MATIC)
If the vehicle has transmission damage or
damage to the front or rear axle, have it trans-
ported on a transporter or trailer.
! New bolts must always be used when the
propeller shafts are refitted. The specified
tightening torques must be observed.
i Consult a Mercedes-Benz Service Centre.
In the event of damage to the electrical
system If the battery is defective, the automatic
transmission will be locked in position
P. To
shift the automatic transmission to neutral,
you must supply power to the vehicle's elec-
trical system in the same way as jump-start-
ing (Y page 329).
Have the vehicle transported on a transporter
or trailer. Fuses
Notes on changing fuses
The fuses in your vehicle serve to close down
faulty circuits. If a fuse blows, all the compo-
nents on the circuit and their functions will
fail.
Blown fuses must be replaced with 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. A Mercedes-
Benz Service 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 work-
shop, 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-Benz vehicles and which have the correct fuse rating for the system
concerned. Otherwise, components or sys-
tems could be damaged.
The fuses are located in various fuse boxes:
R Dashboard fuse box on the front-passenger
side
R Fuse box in the engine compartment on the
right-hand side of the vehicle
R Fuse box in the stowage well under the lug-
gage compartment floor
Fuse allocation chart The fuse allocation chart is located with the
vehicle tool kit (Y
page 252) in the stowage
compartment under the luggage compart-
ment floor. Practical advice

Genuine Mercedes-Benz parts
338 Notes on the 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. These parts have the
same warranty as new parts.
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 340). Technical data

Vehicle electronics
339Vehicle 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 your vehicle's
warranty and operating permit may be inva-
lidated. 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 emark. 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
