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 recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
The vehicle's roadworthiness could other-
wise be affected.
!
Only have work done on the engine elec-
tronics and its associated parts, such as
control units, sensors and connector leads,
carried out at a qualified specialist work-
shop, 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.
Retrofitting electrical and electronic
equipment
Electrical and electronic equipment can jeop-
ardise the operating safety of your vehicle. If
equipment of this kind is retrofitted, it must
be type-approved and bear the e mark. The
e mark may be obtained from the equipment
manufacturer or an authorised testing centre.
!
Damage or consequential damage arising
from fitting equipment not approved by
Mercedes-Benz is not covered by the
Mercedes-Benz warranty.
If you wish to install two-way radios in the
vehicle, you must obtain formal approval.
Mercedes-Benz approves the installation of
two-way radios if such equipment is installed
professionally and a low-reflection exterior
aerial is used.
The transmission output of the two-way radio
must not exceed the maximum transmission
outputs listed.
G Risk of accident
Two-way radios may interfere with the vehi-
cle electronics and thereby jeopardise the
operational safety of the vehicle and your
own safety if:

G Risk of injury
Excessive electromagnetic radiation may
also cause damage to your health and the
health of others. Using an exterior aerial
takes into account current scientific dis-
cussions relating to the possible health haz-
ards that may result from electromagnetic
fields.
For this reason, only have the exterior aerial
fitted at a qualified specialist workshop
which has the necessary specialist knowl-
edge and tools to carry out the work
required. Mercedes-Benz recommends
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.
