WARNING
The wheel/tyre dimensions and the tyre type of the spare wheel/emergency spare wheel
and the wheel to be replaced may differ. Fit- ting a spare wheel/emergency spare wheel
may severely impair the driving characteris-
tics. There is a risk of accident.
8 Use of snow chains not permitted. Observe the notes in the "Snow chains" section.
9 Observe notes on "Large wheels" in the "Wheel/tyre combinations" section. Emergency spare wheel
389Wheels and tyres
Z

To prevent hazardous situations:
R Adapt your driving style accordingly and
drive carefully.
R Never fit more than one spare wheel/emer-
gency spare wheel if the dimensions are
different to those of the wheel being
replaced.
R Only use a spare wheel/emergency spare
wheel briefly if the dimensions are different
to those of the wheel being replaced.
R Do not switch off ESP ®
.
R Have the spare wheel/emergency spare
wheel in question replaced at the nearest
qualified specialist workshop. Make sure
that the wheel/tyre dimensions and tyre
type are correct.
When using an emergency spare wheel or
spare wheel of a different size, you must not
exceed the maximum speed of 80 km/h.
Snow chains must not be fitted to emergency
spare wheels. General notes
Apart from some country-specific variants,
vehicles are not equipped with an emergency spare wheel. Emergency spare wheels are
specific to the vehicle. For more information
on which emergency spare wheels are
approved for your vehicle, consult a qualified
specialist workshop.
You should regularly check the pressure of
the emergency spare wheel, particularly prior to long trips, and correct the pressure as nec-
essary (Y page 362). The value on the wheel is
valid. In addition, the emergency spare wheel
tyre pressure can be found under "Technical
data" (Y page 392).
An emergency spare wheel may also be fitted
against the direction of rotation. Observe the time restriction on use as well as the speed
limitation specified on the emergency spare
wheel. Replace the tyres after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel.
If you are driving with the emergency spare
wheel fitted, the tyre pressure loss warning
system or the tyre pressure monitor cannot
function reliably. Only restart the tyre pres-
sure loss warning system or tyre pressure
monitor when the defective wheel has been
replaced with a new wheel.
Vehicles with tyre pressure monitor: after
fitting an emergency spare wheel, the system
may still display the tyre pressure of the
removed wheel for a few minutes. The value
displayed for the position where the emer-
gency spare wheel is fitted is not the same as
the current tyre pressure of the emergency
spare wheel. Removing the emergency spare wheel
Example: vehicles with the "Minispare" emergency
spare wheel
The "Minispare" emergency spare wheel is
secured in emergency spare wheel bag :in
the luggage compartment.
X Open the tailgate.
X Release securing straps ;on emergency
spare wheel bag :.
X Remove emergency spare wheel bag :

Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 24). Information on 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. Vehicle electronics
Tampering with the engine electron-
ics
! Only have work carried out on the engine
electronics and its associated parts, such
as control units, sensors, actuating com-
ponents and connector leads, at a qualified specialist workshop. Vehicle components
may otherwise wear more quickly and the
vehicle's operating permit may be invalida-
ted. Retrofitting two-way radios and
mobile phones (RF transmitters) G
WARNING
If RF transmitters are tampered with or not
properly retrofitted, the electromagnetic radi- ation they emit can interfere with the vehicle
electronics. This may jeopardise the opera- tional safety of the vehicle. There is a risk of an
accident.
You should have all work on electrical and
electronic components carried out at a quali-
fied specialist workshop. G
WARNING
If you operate RF transmitters incorrectly in
the vehicle, the electromagnetic radiation
could interfere with the vehicle electronics,
e.g.:
R if the RF transmitter is not connected to an
exterior aerial
R the exterior aerial has been fitted incor-
rectly or is not a low-reflection type
This could jeopardise the operating safety of
the vehicle. There is a risk of an accident.
Have the low-reflection exterior aerial fitted at
a qualified specialist workshop. When oper-
ating RF transmitters in the vehicle, always
connect them to the low-reflection exterior
aerial.
! The operating permit may be invalidated if
the instructions for installation and use of
RF transmitters are not observed.
In particular, the following conditions must be complied with:
R only approved wavebands may be used.
R observe the maximum permissible out-
put in these wavebands.
R only approved aerial positions may be
used.
Excessive levels of electromagnetic radiation
may cause damage to your health and to the
health of others. The use of an exterior aerial
takes into consideration the scientific discus- sion surrounding the possible health risk
posed by electromagnetic fields.
Observe the notes on operating mobile
phones (Y page 318).
The following aerial positions may be used for
the correct installation of RF transmitters: 394

Important safety notes G
WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, naked flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before refuelling. G
WARNING
Fuels are poisonous and hazardous to health. There is a danger of injury.
Do not swallow fuel or let it come into contact
with skin, eyes or clothing. Do not inhale fuel
vapours. Keep fuels out of the reach of chil-
dren.
If you or others come into contact with fuel,
observe the following:
R Wash the fuel off any affected areas of skin
with water and soap immediately.
R If you get fuel in your eyes, rinse them thor-
oughly with clean water immediately. Seek immediate medical attention.
R If fuel is swallowed, seek immediate medi-
cal attention. Do not induce vomiting.

use unleaded petrol with an octane rating
of 95 RON. This may reduce engine per-
formance and increase fuel consumption.
As much as possible, avoid driving at full
throttle.
! As a temporary measure, if the recom-
mended fuel is not available, you may also
use unleaded petrol in emergencies with an
octane rating of 91 RON.
Doing so results in noticeably higher fuel
consumption, and the engine power output is noticeably reduced. Avoid driving at full
throttle.
If no fuel other than petrol with 91 RON or a
lower grade is available, you should have
the vehicle adapted to run on this fuel at a
qualified specialist workshop.
Additives ! Operating the engine with fuel additives
added later can lead to engine failure. Do
not mix fuel additives with fuel. This does
not include additives for the removal and
prevention of residue build-up. Petrol must only be mixed with additives recommended
by Mercedes-Benz. Observe the instruc-
tions for use in the product description.
More information about recommended
additives can be obtained from any
Mercedes-Benz Service Centre.
Mercedes-Benz recommends that you use
fuel brands that have additives.
The quality of the fuel available in some coun- tries may not be sufficient. Residue could
build up in the injection system as a result. In
this case, in consultation with a Mercedes-
Benz Service Centre, the petrol may be mixed with the cleaning additive recommended by
Mercedes-Benz. Always observe the notes
and mixing ratios specified on the container. Diesel Fuel grade
G
WARNING
If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of pure diesel fuel. When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is a risk of fire.
Never refuel with petrol. Never add petrol to
diesel fuel.
! When refuelling, only use diesel fuel that
conforms to the European standard EN 590
or is of equivalent quality. Fuel that does
not conform to EN 590 can lead to
increased wear as well as damage to the
engine and exhaust system.
! Do not use the following:
R marine diesel
R heating oil
R bio-diesel
R vegetable oil
R petrol
R paraffin
R kerosene
Do not mix such fuels with diesel fuel and
do not use any special additives. Other-
wise, engine damage may occur.
! Vehicles with diesel particle filters:
in
countries outside the EU, only use low sul-
phur Euro diesel with a sulphur content of
under 50 ppm. Otherwise, the emission
control system could be damaged.
! Vehicles without a diesel particle fil-
ter: in countries where only diesel fuel with
a high sulphur content is available, you will need to carry out your vehicle's oil change
at shorter intervals. More information
about the interval for oil change can be
obtained from any qualified specialist
workshop.
Usually you will find information about the
fuel grade on the pump. If you cannot find the Service products and capacities
