WARNING
All wor konthe vehicle and, in particular ,work
relevant to safet yoronsafety-related sys-
tems must be carried out at aqualified spe-
cialist workshop. The specialist workshop
must have the necessary specialist knowl-
edge and tools to carry out the work required.
Mercedes -Benz recommends that you use a
Mercedes-Benz Ser vice Centre for thi spur-
pose. G
WARNING
Some safety systems only function when the
engine is running. You should therefore never
switch off the engine when driving. Otherwise,
the safety systems of your vehicle may not
function correctly and as aresult will no lon-
ger protec tyou and other person sasinten-
ded .Ina ddition, there is arisk that you may
lose control of your vehicle and thus cause an
accident. G
WARNING
Work carried out incorrectly, or alterations
made to the vehicle, e.g. re-routing of cables
under coverings, could cause the safety sys-
tems of your vehicle to stop working properly.
The safety systems would thus no longer pro-
tect you and other persons as intended. In
addition, there is arisk that you may lose con-
trol of your vehicle and thus cause an acci-
dent.
All work and alteration stothe vehicle, e.g.
installation sormodifications, should there-
for ebec arried out at aqualified specialist
workshop. G
WARNING
If work on electronic equipmen tand its soft-
ware is carried out incorrectly, this equipment
could stop working. The electronic systems
are networ kedv ia interfaces. Tampering with
these electronic systems could cause mal-
func tions in system swhich hav enot been
modified. Malfunction ssuch as these can
seriously jeopardis ethe vehicle' soperating
safety and therefore your own safety.
You should therefore have all work and mod-
ifications to electronic components carried
out at aqualified specialist workshop. G
WARNING
If you drive over obstacle sathigh speed or if
the vehicle bottoms out in rough terrain, it
could cause heavy impact stothe vehicle
underbody, tyres or wheels. This coul dcause
your vehicle to be damaged, which in turn
might lead to an accident. This also applies to
vehicles which are equipped with underbody
protection.
You shoul dtherefore drive over obstacles
slowly. Prevent the vehicle from bottoming
out when driving off-road an difnecessar y,

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

Child restraint systems
Important safety notes G
WARNING
To reduce the risk of serious or even fatal
injury to the child in the event of asudden
change in direction, braking or an accident:
R children less than 1.50 mtall and under
twelve years of age must always be secured
in special child restraint systems on asuit-
able vehicle seat. This is necessary
because the seat belts are not designed for
children.
R do not secure children less than 1.50 mtall
or under twelv eyears of age on th efront-
passenger seat .Exception: the vehicl eis
equipped with automatic child sea trecog-
nition on the front-passenger seat and the
child is secured in achild rest raint system
with transponders for automatic child seat
recognition.
R if you secure aforward-facing child
rest raint system to the front-passenger
seat, you must move the front-passenger
seat as far back as possible.
R children must never travel sitting on the lap
of another occupant .Due to the forces
which occur in the event of asudden
change of direction, heavy braking or an
accident, it would not be possible to
restrain the child. The child could be thrown against parts of the vehicle interior and be
seriously or even fatally injured. G
WARNING
The child restraint system cannot perform its
protective function if it is not correctly fitted
to as uitable vehicle seat. The child cannot be
restrained in the event of an accident, heavy
braking or sudde nchanges of direction. The
chil dcould be seriously or even fatally injured.
For this reason, when fit ting achild rest raint
system, observe the manufacturer's installa-
tion instructions and the correct use of the
child restraint system.
Child restraint systems should be fitted to the
rear seats. Children are generally better pro-
tected there.
The entire base of the child restraint system
must always rest on the seat cushion. There-
fore, never place objects, e.g. acushion,
under the child restraint system.
Only use child restraint systems with the orig-
inal cover designed for them. Only replace
damaged cover swith genuine Mercedes-Benz
covers.
We recommend the use of child restraint sys-
tems which have been approved for
Mercedes-Benz vehicles.
If ac hild is travellin ginyour vehicle, secure
the child using achild restraint system which
is appropriate to the size, age and weight of
the chil dand recommende dfor Mercedes-
Ben zvehicles. You should preferabl yfit the
restraint system to asuitable rear seat. Make
sure that the child is secured in achild
restraint system thr oughout the trip.
Mercedes-Ben zrecommends that you only
use the child restraint system slisted at
(Y page 58).
You can obtain further information about the
correct child restrain tsystem from any
Mercedes-Benz Service Centre.
i It is advisable to use Mercedes-Benz care
products to clean child restraint systems. 50
