2015 MERCEDES-BENZ E-CLASS CABRIOLET change wheel

You could jeopardise the operating safety of
your vehicle if you use parts, tyres and wheels as
well as accessories relevant to safety which
have not been approved by Mercedes-Benz. This
could lead to malfunctions in safety-relevant
systems, e.g. the brake system. Only use genu- ine Mercedes-Benz parts or parts of equal qual-
ity. Only use tyres, wheels and accessories that
have been specifically approved for your vehi-
cle.
Mercedes-Benz tests genuine parts and conver-
sion parts and accessories that have been spe-
cifically approved for your vehicle for their reli-
ability, safety and suitability. Despite ongoing
market research, Mercedes-Benz is unable to
assess other parts. Mercedes-Benz therefore
accepts no responsibility for the use of such
parts in Mercedes-Benz vehicles, even if they
have been officially approved or independently
approved by a testing centre.
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 genuine
Mercedes-Benz parts meet the approval
requirements. The use of non-approved parts
may invalidate the vehicle's general operating
permit.
This is the case:
R if they cause a change 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 number (VIN) (Y page 336) when ordering genuine
Mercedes-Benz parts. Owner's Manual
Vehicle equipment
i This Owner's Manual describes all models
and all standard and optional equipment
available for your vehicle at the time of pub-
lication of the Owner's Manual. Country-spe-
cific differences are possible. Note that your
vehicle may not be fitted with all features
described. This is also the case for systems
and functions relevant to safety. Therefore,
the equipment on your vehicle may differ from that in the descriptions and illustrations. The original purchase contract documentation
for your vehicle contains a list of all of the sys-
tems in your vehicle.
Should you have any questions concerning
equipment and operation, please consult a
Mercedes-Benz Service Centre.
The Owner's Manual and Service Booklet are
important documents and should kept in the
vehicle. Operating safety

WARNING
If you do not have the prescribed service/
maintenance work or necessary repairs car-
ried out, this could result in malfunctions or
system failures. There is a risk of an accident. Always have the prescribed service/mainte-
nance work as well as necessary repairs car-
ried out at a qualified specialist workshop. G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system. There is a risk of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop. G
WARNING
Modifications to electronic components, their software as well as wiring could affect their
function and/or the operation of other net-
worked components. This could in particular
also be the case for systems relevant to
safety. They might not function properly any-
more and/or jeopardise the operational
safety of the vehicle. There is an increased
risk of an accident and injury.
Do not attempt to modify the wiring as well as
electronic components or their software. Operating safety
25Introduction
Z

Always have work on electrical and electronic
components carried out at a qualified special-ist workshop.
If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid.
! There is a risk of damage to the vehicle if:
R the vehicle becomes stuck, e.g. on a high
kerb or an unpaved road
R you drive too fast over an obstacle, e.g. a
kerb or a pothole in the road
R a heavy object strikes the underbody or
parts of the chassis
In situations like this, the body, the under-
body, chassis parts, wheels or tyres could be
damaged without the damage being visible.
Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no
longer withstand the strain they are designed for.
If the underbody panelling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody panelling. If these materials
come in contact with hot parts of the exhaust
system, they can catch fire.
In such situations, have the vehicle checked
and repaired immediately at a qualified spe-
cialist workshop. If, upon continuing your
journey, you notice that driving safety is
impaired, pull over and stop the vehicle imme- diately, paying attention to road and traffic
conditions. In such cases, consult a qualified
specialist workshop. Declarations of conformity
Wireless vehicle components The following information applies to all compo-
nents of the vehicle and the information sys-
tems and communication devices integrated
into the vehicle which receive and/or transmit
radio waves:
The components of this vehicle that receive
and/or transmit radio waves are compliant with
the basic requirements and all other relevant
conditions of Directive 1999/5/EC. You can
obtain further information from any Mercedes-
Benz Service Centre. Electromagnetic compatibility The electromagnetic compatibility of the vehicle
components has been checked and certified
according to the currently valid version of Reg-
ulation ECE-R 10. Diagnostics connection
The diagnostics connection is only intended for the connection of diagnostic equipment at a
qualified specialist workshop. G
WARNING
If you connect equipment to a diagnostics
connection in the vehicle, it can affect the
operation of the vehicle systems. This may
affect the operating safety of the vehicle.
There is a risk of an accident.
Do not connect any equipment to a diagnos-
tics connection in the vehicle. G
WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardises the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
Always fit the floormats securely and as pre-
scribed in order to ensure that there is always sufficient room for the pedals. Do not use
loose floormats and do not place several floor-mats on top of one another.
! If the engine is switched off and equipment
on the diagnostics connection is used, the
starter battery may discharge.
Connecting equipment to the diagnostics con-
nection can lead to emissions monitoring infor-
mation being reset, for example. This may lead
to the vehicle failing to meet the requirements of
the next emissions test during the main inspec- tion. 26
