i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviation sare possible .Please
not ethat your vehicle ma ynot be equipped
with all featur es described. This also
applies to safety-releva ntsystems and
functions.

Important safet
ynotes
Seat belts, together wit hthe Supp lemental
Restrain tSyste m–S RS (Y page 41), are
complementary, co-ordinated restrain tsys-
tems. They reduce the risk of injur yinspe-
cific, pre-defined types of accident situations
and thereby increase occupant safety .How-
ever ,seat belts and airbags generally do not
protec tagainst objec tspenetratin gthe vehi-
cle from the outside.
To ensur ethat the restraint system scan
deliver their full potential protection, make
sure that:
R the seat and head restraint are adjusted
properly (Y page 92).
R the seat belt has been fastened properly
(Y page 47).
R the airbags can inflate unrestricted if
deplo yed (Y page42).
R the steering whee lisadjusted properly
(Y page 92).
R the restraint systems have not been modi-
fied.
i An airba gincrease sthe protection of
vehicle occupants wearing aseat belt. As
such, they are only an additional restraint
system which complemen ts,b ut 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. The airbags are not deplo yed inall
types of accidents. For example, if the pro-
tective capacity of correctly fastened seat
belts is not increased by deplo yingthe air-
bags, the airbags will not deploy. Airbag
deploymen tonly provides incre asedpro-
tection if th eseatb eltisw ornc orrect ly
because:
R the sea tbelt helps to keep the vehicle
occupan tinthe best position in relation
to the airbag.
R in ah ead-on collision ,for example, the
seat belt prevents the vehicle occupant
from being propelled towards the point
of impact .Itcan thus reduce the risk of
injury.
In accidents in which an airbag is deployed,
it provides increased protection only if the
seat belt is worn correctly. G
WARNING
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 carr yout the work required.
Mercedes-Ben zrecom mends 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 aq ualified specialist workshop. 40
