Emergency spare wheel
Important safety notes
G
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.
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 all your tyres, including the emergency spare
wheel, particularly prior to long trips, and cor- rect the pressure as necessary (Y page 356).
The value on the wheel is valid. In addition, the
emergency spare wheel tyre pressure can be found under "Technical data" (Y page 382).
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/tyre pressure mon- itor when the defective wheel has been
replaced with a new wheel.
Vehicles with tyre pressure monitor: after
mounting an emergency spare wheel, the sys- tem 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

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
You can find current technical data on the
Internet on our Mercedes ‑Benz homepage.
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- 384
Vehicle electronicsTechnical data

sion surrounding the possible health risk
posed by electromagnetic fields.
Observe the notes on operating mobile
phones (Y page 314).
The following aerial positions may be used for the correct installation of RF transmitters: Approved aerial positions
:
Front roof area
; Rear roof area
= Rear wing
i On vehicles with panorama sliding sun-
roof, fitting an aerial to the front or rear roof
area is not permitted.
On the rear wing, it is recommended that
you position the aerial on the side of the
vehicle closest to the centre of the road.
Use Technical Specification ISO/TS 21609
(Road Vehicles – "EMC guidelines for fitting
aftermarket radio frequency transmitting
equipment") when retrofitting RF (radio fre-
quency) transmitters. Comply with the legal
requirements for add-on parts.
If your vehicle has fittings for two-way radio
equipment, use the power supply or aerial
connections intended for use with the basic
wiring. Be sure to observe the manufacturer's additional instructions when installing.
Deviations with respect to wavebands, maxi-
mum transmission outputs or aerial positions must be approved by Mercedes-Benz. The maximum transmission output (PEAK) at
the base of the aerial must not exceed the
following values: Waveband Maximum
transmission output Short wave
3 - 54 MHz 100 W
4 m waveband
74 - 88 MHz 30 W
2 m waveband
144 - 174 MHz 50 W
Trunked radio/Tetra
380 - 460 MHz 10 W
70 cm waveband
400 - 460 MHz 35 W
2G/3G/4G mobile com-
munications generations 10 W
The following can be used in the vehicle with-
out restrictions:
R RF transmitters with a maximum transmis-
sion output of up to 100 mW
R RF transmitters with transmission frequen-
cies in the range 380-410 MHz and a max-imum transmission output of 2 W (Tetra)
R Mobile telephones (2G/3G/4G)
There are no restrictions when positioning the aerial on the outside of the vehicle for the fol-
lowing wavebands:
R Trunked radio/Tetra
R 70 cm waveband
R Mobile communications (2G/3G/4G) Vehicle electronics

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
