The operating safety of your vehicle could be compromised if service work is carried out improp-
erly. You could lose control of the vehicle and cause an accident. Safety systems may also not
be able to protect you or others as intended.
Always have maintenance work carried out at a qualified specialist workshop. The workshop must
have the necessary specialist knowledge and tools to carry out the work required. Mercedes- 182 Display messagesPractical advice

Tampering with the engine electron-

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 recom-
mends that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop. Otherwise, the vehicle’s
roadworthiness could be affected.
! Only have maintenance work on the
engine electronics and its associated parts,
such as control units, sensors and connec-
tor leads, performed at a qualified special-
ist workshop, e.g. a Mercedes-Benz Service
Centre. Otherwise, vehicle components
may wear more quickly and your vehicle's
warranty and operating permit may be inva-
lidated. Retrofitting electrical and electronic
equipment
Electrical and electronic equipment can jeop-
ardise the operating safety of your vehicle. If
equipment of this kind is retrofitted, it must
be type-approved and bear the emark. The
e mark may be obtained from the equipment
manufacturer or an authorised testing centre.
! Damage or consequential damage arising
from fitting equipment 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 installed
professionally and a low-reflection exterior
aerial is used.
The transmission output of the two-way radio
must not exceed the maximum transmission
outputs listed.
G
Risk of accident
Two-way radios may interfere with the vehicle
electronics and thereby jeopardise the opera-
tional safety of the vehicle and your own
safety if:
R they do not have an exterior aerial.
R the exterior aerial is not a low-reflection
aerial.
R the exterior aerial has been fitted incor-
rectly. G
Risk of injury
Excessive electromagnetic radiation could
result in damage to your health. Using an
exterior aerial takes into account current sci-
entific discussions relating to the possible
health hazards that may result from electro-
magnetic fields.
For this reason, only have the exterior aerial
fitted 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 pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at a qualified specialist workshop.
i Mercedes-Benz recommends the use of
an approved exterior aerial. This ensures
optimal reception quality for mobile tele-
phones/wireless devices in the vehicle.
This also ensures that interference
between these devices and the vehicle's
electronics is kept to a minimum. If con-
nected, the exterior aerial conducts the
electromagnetic fields transmitted by a
mobile phone to the exterior of the vehicle. Vehicle elect
