WARNING
The wheel/tyr edimension sand th etyret ype
of th espar ew heel/emergency spar ewheel
and th ewheel to be replaced may differ. Fit-
tin gas parew heel/emergency spar ewheel
may severel yimpair th edriving characteris-
tics. Ther eisarisk of accident.
To prevent hazardous situations:
R Adap tyour driving style accordingly and
drive carefully.
R Never fit more than one spare wheel/emer-
gency spare wheel if the dimesions are dif-
ferent to those of the wheel being replaced.
R Only use aspare wheel/emergency spare
wheel briefly if the dimesions 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 emergenc yspare wheel or
spare wheel of adifferent size, you must not
exceed the maximum speed of 80 km/h.
Snow chains must not be fitted to emergency
spare wheels. General notes
You should regularly check the pressure of all
your tyres, including the emergenc yspare
wheel, particularly prior to long trips, and cor-
rect the pressure as necessary (Y page 331).
The applicabl evalue is found on the wheel or
under "Technical data" (Y page 354).
An emergenc yspare 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.
i
When you are drivin gwith the collapsible
emergency spare wheel fitted, the tyre
pressure loss warning system or the tyre
pressure monitor cannot function reliably.
Only restart the tyre pressure loss warning
system/tyre pressure monitor when the
defective wheel has been replaced with a
new wheel.
Vehicles with tyr epressure monitor:
after mounting an emergency spare wheel,
the system may still display the tyre pres-
sure of the removed wheel for afew
minutes. The value displayed for the moun-
ted emergency spare wheel is not the same
as the curren ttyre pressure of the emer-
genc yspare wheel. Removing the "Minispare" emer-
gency spar

! Inflate the collapsible emergency spare
wheel using the tyre inflation compressor
before lowering the vehicle. The wheel rim
could otherwise be damaged.
! Do not operate the tyre inflation com-
pressor for longer than eight minutes at a
time without abreak. It may otherwise
overheat.
The tyre inflation compressor can be oper-
ated again onceith as cooled down. X
Mount the collapsible emergency spare
wheel as described (Y page 336).
The collapsible emergency spare wheel
must be mounted before it is inflated.
X Pull connector ?and the air hose out of
the housing.
X Remove the cap from the valve on the col-

The specified tyre pressure is printed on
the yellow label of the emergency spare
wheel.
X When the specified tyre pressure has been
reached, press on/off switch Aon the

WARNING
Drivin gsafety may be impaired if non-
approved parts, tyres and wheels or safety-
relevant accessories are used.
This could lead to malfunctions in safety-rel-
evant systems, e.g. the brake system. This
could cause you to lose control of your vehicle
and cause an accident.
For this reason, Mercedes-Benz recommends
that you use genuine Mercedes-Benz parts or
parts of equal quality. Only use tyres, wheels
and accessories that have been specifically
approved for your vehicle. H
Environmental note
Daimler AG also supplies reconditioned
assemblies and parts which are of the same
quality as new parts. For these, the same war-
ranty applies as for new parts.
! Airbags and seat belt tensioners, as well
as control units and sensors for these
restraint systems, may be installed in the
following areas of your vehicle:
R doors
R door pillars
R door sills
R seats
R dashboard
R instrument cluster
R centre console
Do not install accessories such as audio
systems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficienc yofthe restraint sys-
tems.
Have accessories retrofitted at aqualified
specialist workshop.
Mercedes-Benz testsg enuine parts and con-
version parts and accessories that have been
specifically approved for your vehicle for their
reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benz is
unable to assess other parts. Mercedes-Benz
accepts no responsibility for the use of parts
that have been independently or officially
approved.
In Germany, certain parts are only officially
approved for installation or modification if
they comply with legal requirements. This
also applies to some other countries. All gen-
uine Mercedes-Benz parts meet the approval
requirements. The use of non-approved parts
may invalidate the vehicle's general operating
permit. 356
Genuine Mercedes-Benz partsTechnical data

This is the case:
R
if they cause achange of the vehicle type
from that for which the vehicle's general
operating permit was granted
R if other road users could be endangered
R if the emission or noise levels are adversely
affected.
Always specify the vehicle identification num-
ber (VIN) (Y page 359) and the engine num-
ber (Y page 359) when ordering genuine
Mercedes-Benz parts. Vehicle electronics

ting equipment installed at aqualified spe-
cialist workshop. G
WARNING
Incorrect retrofittin gofRFtransmitters can
lead to increased electromagnetic radiation in
the vehicle interior. Using an exterior aerial
takes into account curren tscientific discus-
sions relating to the possible health hazards
that may result from electromagnetic fields.
Have aftermarket radio frequency transmit-
ting equipment installed at aqualified spe-
cialist workshop.
! 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:
