Vehicle equipment
i This manual describes all the standard
and optional equipment of your vehicle
available at the time of publicatio nofthe
Owner's Manual. Country-specific differen-
ces are possible. Please note that your
vehicle may not be equipped with all fea-
tures described. This also applies to safety-
relevant systems and functions. Occupant safety
Important safety notes
Seat belts, together with belt tensioners, belt
force limiters and airbags, are complemen-
tary, coordinated restraint systems. They
reduce the risk of injury in specific, pre-
defined types of accident situations and
thereby increase occupant safety. However,
seat belts and airbags generally do not pro-
tect against objects penetrating the vehicle
from the outside.
To ensure that the restraint systems can
deliver their full potential protection, make
sure that:
R the seat and head restraint are adjusted
properly (Y page 84).
R the seat belt has been fastened properly
(Y page 43).
R the airbags can inflate unrestricted if
deployed (Y page 36).
R the steering wheel is adjusted properly
(Y page 84).
R the restraint systems have not been modi-
fied.
i An airbag increases the protection of
vehicle occupants wearing a seat belt. As
such they are only an additional restraint
system which complements, but does not
replace, the seat belt. All vehicle occupants
must wear their seat belt correctly at all
times, even if the vehicle is equipped with
airbags. Airbags are not deployed in all
types of accidents, e.g. in situations where airbag deployment would not increase the
protection afforded by a correctly worn
seat belt. Airbag deployment only provides
increased protection if the seat belt is worn
correctly because:
R the seat belt helps to keep the vehicle
occupant in the best position in relation
to the airbag.
R for example, in a head-on collision, the
seat belt can more adequately prevent
the occupant from being propelled
towards the point of the impact, and is
thus better suited to prevent injury.
Therefore, in accident situations where an
airbag is deployed, it only provides protec-
tion in addition to the seat belt if the seat
belt is being worn correctly. G
Risk of accident and injury
If service work is not carried out correctly, the
operating safety of your vehicle may be affec-
ted. This could cause you to lose control of
your vehicle and cause an accident. More-
over, the safety systems may no longer be
able to protect you or others as they are
designed to do.
Always have service work carried out at a
qualified specialist workshop. The workshop
must have the necessary specialist knowl-
edge and tools to carry out the work required.
Mercedes-Ben zrecommends 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. G
Risk of injury
Modifications to or work performed incor-
rectly on the following parts can result in the
restraint systems not functioning as intended:
R the restraint system, consisting of seat
belts and their anchorage points, belt ten-
sioners, belt force limiters and airbags
R the wiring
R networked electronic systems 34

when retrofitting RF (radio frequency) trans-
mitters.
If your vehicle has fittings for two-way radio
equipmen t(e.g. taxis, hire cars or official vehi-
cles), use the power supply or aerial connec-
tions intended for use with the basic wiring.
Be sure to observe the manufacturer's addi-
tional instructions when installing the fittings.

mitting equipment installed at a qualified

Risk of accident
Incorrect retrofitting of RF transmitters can
cause the vehicle electronics to malfunction.
The vehicle's operating safety and thus your
own safety are impaired.
Have aftermarket radio frequency transmit-
ting equipment installed at a qualified spe-
cialist workshop. Mercedes-Benz recom-
mends that you use a Mercedes-Benz Service
Centre for this purpose. G
Risk of injury
Incorrect retrofitting of RF transmitters can
lead to increased electromagnetic radiation in
the vehicle interior. Using an exterior aerial
takes into account current scientific discus-
sions relating to the possible health hazards
that may result from electromagnetic fields.

ting equipment installed at a qualified spe-
