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 purpose. In particu-
lar, work relevant to safety or on safety-re-
lated systems must be carried out at a quali-
fied specialist workshop. The vehicle's road-
worthiness could otherwise be affected.
!
Only have work done on the engine elec-
tronics and its associated parts, such as con-
trol units, sensors and connector leads, carried
out at a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre. Otherwise, ve-
hicle components may wear more quickly and
the warranty and vehicle's general operating
permit may be invalidated.

Retrofitting electrical and electronic
equipment
Electrical and electronic equipment can
jeopardise the operating safety of your ve-
hicle. If equipment of this kind is retrofit-
ted, it must be type-approved and bear the
e mark. The e mark may be obtained from
the equipment manufacturer or an author-
ised testing centre.
!
Damage caused by or as a consequence of
fitting equipment that is 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 in-
stalled professionally and a low-reflection
exterior aerial is used.
The transmission output of the two-way ra-
dio must not exceed the maximum trans-
mission outputs listed.
G
Risk of accident
Two-way radios may interfere with the ve-
hicle electronics and thereby jeopardise the
operational safety of the vehicle and your
own safety if:

I they do not have an exterior aerial
I the exterior aerial is not a low-reflection
aerial
I the exterior aerial has been fitted incor-
rectly
G
Risk of injury
Excessive electromagnetic radiation may al-
so cause damage to your health and the
health of others. Using an exterior aerial
takes into account current scientific discus-
sions relating to the possible health hazards
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 re-
quired. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for
this purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist work-
shop.

To ensure optimum reception quality for
mobile phones and two-way radios in the ve-
hicle, and to minimise mutual influences be-
tween the vehicle electronics and mobile
phones/two-way radios, Mercedes-Benz rec-
