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. Therefore, the data may differ for
vehicles with optional equipment. You can
obtain further information from a
Mercedes-Benz Service Centre.
You can find technical data on the Internet at:
www.mercedes-benz.com 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. Therefore,
Mercedes-Benz 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. Therefore,
Mercedes-Benz recommends genuine
Mercedes-Benz parts and conversion parts
and accessories that have been approved for
your vehicle. H
Environmental note
Daimler also supplies reconditioned assem-
blies and parts which are of the same quality
as new parts. For these, the same warranty
applies as for 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
your vehicle's identification plates, for exam-
ple (Y page 396). Vehicle 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 recom-
mends 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 spe-
cialist workshop. Otherwise, the vehicle’s
roadworthiness could be affected.
! Only have maintenance work on the
engine electronics and its associated parts,
such as control units, sensors and connec-
tor leads, performed at a qualified special-
ist workshop, 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. 394

24-GHz radar sensor system* (coun-
try overview)
The 24 GHz radar sensor system requires
separate approval for each country. When
you are driving in a country in which the radar
sensor system is not approved, you must
deactivate the system using the on-board
computer (Y page 226). The current country
overview can be obtained from a Mercedes-
Benz Service Centre.
Vehicles with COMAND and navigation
system*: the radar sensor system is deacti-
vated automatically near radio telescope
facilities. If Distronic Plus*, Park Assist*, Parking Guidance*, Blind Spot Assist* or
PRE-SAFE
®
Brake* are activated at this point,
a corresponding warning will appear in the
multi-function display to tell you that the
radar sensor system is being switched off.
BAS PLUS* is also no longer available. If the
deactivation does not occur automatically,
you must deactivate the radar sensor system
using the on-board computer (Y page 226).
Vehicles without COMAND and naviga-
tion system* and vehicles for Australia:
deactivate the radar sensor system in the on-
board computer when you are near a radio
telescope facility (Y page 226). Country Radio telescope
