Modification sto electronic components, their
software as well as wirin gcan impair their
function and/o rth efunction of other net-
worke dcomponents. In particular, systems
relevan tto safet ycould also be affected. As a
result ,these may no longer function as inten -

Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print. Country-specific variations are possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 31).
Vehicle electronics
Tampering with the engine electron-
ics
!
Only have engine electronics and the corre-
sponding parts, such as control units, actua-
tors, sensors or connector leads, serviced at a
qualified specialist workshop. Otherwise, the
vehicle parts may wear more quickly. This can
lead to loss of the New Vehicle Limited War-
ranty.
Installing electrical or electronic
equipment
You and others can suffer health-related dam-
age through electromagnetic radiation. By using
an exterior antenna, a possible health risk
caused by electromagnetic fields, as discussed
in scientific circles, is taken into account. Only
have the exterior antenna installed by a qualified specialist workshop.
Electrical and electronic devices may have a
detrimental effect on both the comfort and the
operating safety of the vehicle. If equipment of
this kind is installed, its electromagnetic com-
patibility must be checked and verified.
If these devices are linked to functions associ-
ated with resistance to interference, they must
have type approval. This applies to the device or
its interfaces to the vehicle electronics, e.g.
charging brackets.
A telephone or two-way radio to be installed in
the vehicle must be approved. You can obtain
further information from any Mercedes-Benz
Commercial Van Center. For operation of mobile phones and two-way
radios, Mercedes-Benz recommends connec-
tion to an approved exterior antenna. This is the
only way to ensure optimum reception quality
inside the vehicle and to minimize mutual inter-
ference between the vehicle electronics, mobile
phones and two-way radios.
The transmission output of the mobile phone or
two-way radio may not exceed the following
maximum transmission output (PEAK):
Frequency rangeMaximum trans-
mission output
