WARNING
All work on the vehicle and, in particular, work
relevant to safety or on safety-related sys-
tems must be carried out at aqualified spe-
cialist workshop. G
WARNING
Some safety systems only function when the
engine is running. You should therefor enever
switch off the engine when driving. Otherwise,
the safety systems of your vehicle may not
function correctly and as aresult will no lon-
ger protect you and other persons as inten-
ded. In addition, 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 alterations to the vehicle, e.g.
installations or modifications ,should there- 22

WARNING
If work on electronic equipmen tand its soft-
ware is carried out incorrectly, this equipment
could stop working .The electronic systems
are networked via interfaces. Tampering with
these electronic systems could cause mal-
functions in systems which have not been
modified. Malfunctions such as these can
seriously jeopardise the vehicle's operating
safety and therefore your own safety.
You should therefore have all work and mod-
ifications to electronic components carried
out at aqualified specialist workshop. Declarations of conformity

WARNING
If you wish to use seat covers, Mercedes-Benz
recommends that, for safety reasons, you
only use seat covers that have been approved
for Mercedes-Ben zvehicles.
The seat cover smust have aspecial tear seam
for sidebags/pelvisbags. Otherwise, the side-
bag/pelvisbag cannot deploy correctly and
would fail to provide the intended protection
in the event of an accident. Appropriate seat
cover scan be obtained, for example, from a
Mercedes-Benz Service Centre. Fron
tsidebags :and rear sidebags ;
deploy nex ttothe outer seat cushions. When deployed, the sidebags offer additional
protection for the thorax of the vehicle occu-
pants on the side of the vehicle on which the
impact occurs. However, they do not protect
the:
R head
R neck
R arms
The sidebags are deployed:
R on the side on which an impact occurs
R at the start of an accident with ahigh rate
of lateral vehicle deceleration or accelera-
tion, e.g. in aside impact
R independently of the use of the seat belt
R independently of the front airbags
R independently of the belt tensioners
If the vehicle overturns, the sidebags are gen-
erally not deployed. Sidebags are deployed if
the system detect shigh vehicle deceleration
or acceleration in alateral direction and
determines that sidebag deployment can
offer additional protection to that provided by
the seat belt.
Pelvisbags G
WARNING
If you wish to use seat covers, Mercedes-Benz
recommends that, for safety reasons, you
only use seat covers that have been approved
for Mercedes-Benz vehicles.
The seat covers must have aspecial tear seam
for sidebags/pelvisbags. Otherwise, the side-

ing of belt tensioners. Any Mercedes-Benz
Service Centre can provide details of these
regulations.
! If the front-passenger seat is not occu-
pied, do not engage the seat belt tongue in
the buckle on the front-passenger seat.
Otherwise, the belt tensioner could be trig-
gered in the event of an accident.
The seat belts are fitted with belt tensioners.
The belt tensioners tighten the seat belts in
an accident, pulling them close against the
body.
Belt tensioners do not correct incorrects eat
positions or incorrectly fastened seat belts.
Belt tensioners do not pull vehicle occupants
back towards the backrest.
If the seat belt is also fitted with abelt force
limiter and this is triggered, the force exerted
by the seat belt on the vehicle occupant is
reduced.
The belt force limiters for the front seats are
synchronised with the front airbags, which
take on apart of the deceleration force. This
results in the force exerted on the occupant
being distributed over agreater area.
The belt tensioners can only be activated
when:
R the ignition is switched on.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 41).
R the belt tongue is engaged in the buckle on
each of the three-point seat belts in front.

If the airbags are deployed, you will hear a
bang, and asmall amount of powder may also
be released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard. The 6SRS warning lamp

WARNING
To reduce the risk of serious or even fatal
injur ytot he child in the event of asudden
change in direction, brakin goranaccident:
R children less than 1.5 0mtall and under
twelve years of age must alway sbesecured
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 drive with achild secured in arear-
ward-facin gchild restraint system on the
front-passenger seat. Exception: if the vehi-
cle is equipped with automatic child seat
recognition on the front-passenger seat
and the child is secured in achild restraint

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 wouldn ot 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 sudden changes of direction. The
child could be seriously or even fatally injured.
For this reason, when fitting achild restraint
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 covers with genuine Mercedes-Benz
covers.
We recommend the use of child restraint sys-
tems which have been approved for
Mercedes-Benz vehicles. G
WARNING
Do not leave children unsupervised in the
vehicle, even if they are secured in achild
restraint system. They could injure them-
selves on parts of the vehicle. They could also
be seriously or even fatally injured by pro-
longed exposure to extreme heat or cold.
Do not expose the child restraint system to
direct sunlight. Parts of the child restraint sys- tem could heat up and the child could burn
herself/himself on them.
If
ac hild opens adoor, the child or other per-
sons could be injured as aresult. They could
get out and injure themselves or be injured by
ap assing vehicle.
Observe the general notes on the HOLD func-
tion, which can be found under the same key-
word. G
WARNING
Unsecured or incorrectly positioned loads
increase the risk of injury for children and all
other occupants in the event of:
R an accident
R sudden braking
R as udden change of direction
Do not transport heavy or hard objects in the
vehicle interior unless they are secured. You
will find further information under "Loading
guidelines" in the index.
If ac hild is travelling in your vehicle, secure
the child using achild restraint system which
is recommended for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child.
Ideallyt he child restraint system should be
installed on asuitabler ear seat. Make sure
that the child is secured for the trip.
Mercedes-Benz recommends that you use
the listed child restraint systems
(Y page 60). You can obtain further infor-
mation aboutt he correct child restraint sys-
tem from any Mercedes-Ben zService Centre.
