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 components
and connector leads, at a qualified specialist
workshop. Vehicle components may other-
wise wear more quickly and the vehicle's
operating permit may be invalidated.
Fitting 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-
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 output
R
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.
Approved aerial positions
Rear wings
:
On the rear wings, it is recommended that you
position the aerial on the side of the vehicle
closest to the centre of the road.
Use Technical Specification ISO/TS 21609
(Road Vehicles – "EMC guidelines for installa-
tion of aftermarket radio frequency transmitting
equipment") when retrofitting RF transmitters.
Comply with the legal requirements for add-on
parts.
If your vehicle has fittings for two-way radio
equipment, use the power supply or aerial con-
nections intended for use with the basic fittings.
Be sure to observe the manufacturer's addi-
tional instructions when installing.
