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-
page 28).
Y
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.:
if the RF transmitter is not connected to an
R
exterior aerial
the exterior aerial has been fitted incor-
R
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:
only approved wavebands may be used.
R
observe the maximum permissible out-
R
put in these wavebands.
only approved aerial positions may be
R
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-
sion surrounding the possible health risk
posed by electromagnetic fields.
