Vehicle electronics

Tampering with the engine electron-
ics
G
WARNING
Modifications to electronic components, their
software as well as wiring could effect 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.
Always have work on electrical and electronic
components carried out at a qualified special-
ist workshop.
G
WARNING
The function of systems or components can
be affected by conversions or modifications
to the vehicle. They might not function prop-
erly any more and/or jeopardise the opera-
tional safety of the vehicle. There is an
increased risk of an accident and injury.
Conversions or modifications should always
be carried out at qualified specialist work-
shop.
! Only have work carried out on the engine
electronics and its associated parts, such
Vehicle electronics
as control units, sensors and connector
leads, at a qualified specialist workshop.
Vehicle components may otherwise wear
more quickly and the vehicle's operating
permit may be invalidated.
Retrofitting two-way radios and
mobile phones (RF transmitters)
G
WARNING
If you use the RF transmitter in the vehicle in
an improper way, its electromagnetic radia-
tion can disrupt vehicle electronics, e.g. if:
the RF transmitter is not connected to an
R
exterior aerial
the exterior aerial is fitted incorrectly or is
R
not a low-reflection aerial
This can 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 in the vehicle, always connect the RF
transmitter to the low-reflection exterior aer-
ial.
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.
! The operating permit may be invalidated
if the instructions for installation and use of
RF transmitters are not observed.
