Belt warning for the driver and front
passenger
The
7 seatbelt warning lamp in the instru-
ment cluster is a reminder for all occupants
to fasten their seat belts. It may light up con-
tinuously or flash. In addition, there may be a
warning tone.
The 7 seat belt warning lamp goes out and
the warning tone ceases when the driver and
the fron tpassenger have fastened their seat
belt.
For certain countries only: regardless of
whether the driver and th efront passenger
have fastened their seat belts, the 7seat
beltw arning lamp lights up for six seconds
after the engine is started. It then goes out if
the driver and the fron tpassenger have fas-
tened their seat belts.
i Further information about the 7seat
belt warning lamp (Y page 252).
Rear seat belt status indicator The rear-compartmen
tseat belt status indi-
cator tells you if the rear passengers have
their seat belts fastened.
The rear-compartment seat belt status indi-
cator indicates the rear seat on which the belt
is fastened. The üsymbol in the multi-
function display indicates afastened seat
belt .Ifaseat belt is not fastened or if a seat
is not occupied, the ýsymbol is displayed.
The rear-compartments eat belt status indi-
cator appears in the multifunction display for
around 30 seconds if:
R you drive off and reach a speed of approx-
imately 10 km/h.
R the rear passengers fasten or unfasten
their seat belts while the vehicle is in
motion.
R someone gets in or out of the vehicle and
the vehicle drives off again.
You can also cancel the rear seat belt status
indicator immediately (Y page 228).i
The status indicator for the rear-compart-
ment seat belts is only available for certain
countries.
Belt tensioners, belt force limiters G
WARNING
The belt tensioners in the rear only function if
the belt buckles can be pulled down unob-
structed. They must not be restricted in any
way. Therefore, do not grab the belt buckles
and do not place any objects under the belt
buckles. Otherwise, the tensioning of the belt
by the buckle is restricted or will not function,
and will not provide any additional protection. G
WARNING
If the seat belt tensioners have been trig-
gered, they provide no additional protection
in the event of another accident. Therefore,
have belt tensioners which have been trig-
gered replaced at a qualified specialist work-
shop.
Comply with safety regulations when dispos-
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.
X In order to ensure that the pyrotechnic seat
belt tensioners have not been triggered,
always have the seat belts checked after an
accident.
If the belt tensioners have been triggered,
they must be replaced.
The fron tseat belts and the outer seat belts
in the rear are equipped with belt tensioners
and belt force limiters.
The belt tensioners tighten the seat belts in
an accident, pulling them close against the
body. Occupant safety

The front-passenger airbag is not disabled:
R
on vehicles without automatic child seat
recognition on the front-passenger seat
R in vehicles with automatic child seat rec-
ognition in the front-passenger seat, if no
special child restraint system with trans-
ponders for automatic child seat recogni-
tion in the front-passenger seat has been
fitted
R on vehicles with automatic child seat rec-
ognition on the front-passenger seat, if the
PASSENGER AIRBAG OFF indicator lamp
4 is not lit.
To make you aware of this danger, a corre-
sponding warning sticker has been affixed on
the dashboard and on both sides of the sun
visor on the front-passenger side.
Information about recommended child
restraint systems is availabl eatany
Mercedes-Benz Service Centre. Example: warning notice on the front-passenger
su
nv isor Warning symbol for a rearward-facing child
restraint system Do not use a rearward-facing child restraint
syste monaseat that is protected by an air-
bag installed in front of it.
Automatic child seat recognition on the
front-passengers eat G
WARNING
If the 4 PASSENGER AIRBAG OFF indica-
to rlamp does no tlight up when the child
restraint system is fitted, the front-passenger
airbag has not been disabled. If the front-
passenger airbag deploys, the child could be
seriously or even fatally injured.

WARNING
During the charging process, a battery produ-
ces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.
R Make sure that the positive terminal of a
connected battery does not come into con-
tact with vehicle parts.
R Never place metal objects or tools on a bat-
tery.
R It is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting a battery.
R When jump-starting, make sure that the
battery poles with identical polarity are
connected.
R It is particularly important to observe the
described order when connecting and dis-
connecting the jump leads.
R Never connect or disconnect the battery
terminals while the engine is running. G
WARNING
Electrostatic build-up can lead to the creation
of sparks, which could ignite the highly explo-
sive gases of a battery .There is a risk of an
explosion.
Before handling the battery, touch the vehicle
body to remove any existing electrostatic
build-up. G
WARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with the skin, eyes or clothing.
Do not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash battery acid immediately with
water and seek medical attention.
! Have the battery checked regularly at a
qualified specialist workshop.
Observe the service intervals in the Service
Booklet or contact a qualified specialist
workshop for more information. !
Always have work on the battery carried
out at a qualified specialist workshop.
Should it, in exceptional circumstances, be
absolutely necessary to disconnectt he bat-
tery yourself, please observe the following:
R switch off the engine and remove the
key. Check that all the indicator lamps in
the instrumentc luster are off.Otherwise,
you may damage electroni ccomponents
such as the alternator, for example.
R first, disconnect the negative terminal
clamp, followed by the positive terminal
clamp. Never swap the terminal clamps.
The vehicle electronics may otherwise be
damaged.
R on vehicles with automatic transmission,
the transmission is locked in position P

Battery (vehicle)Breakdown assistance

Do not use a rapid charging device to start the vehicle.
Make sure the jump leads are not damaged.
Make sure the jump leads are not touching any other metal objects when they are connected
to the battery.
If the indicator/warning lamps do not ligh tup at temperatures around or below freezing point,
the discharged battery is likely to be frozen (a commonplace scenario). In this case, do not
jump-start the vehicle or recharge the battery.
Once the battery has thawed out, its service life may be dramatically reduced.
The starting characteristic scan be impaired, particularly at low temperatures.
It is recommended that you have the thawed out battery checked at a qualified specialist
workshop.
Do no tuse a rapid charging device to start the vehicle. If your vehicle's battery is discharged,
the engine can be jump-started from another vehicle or from a second battery using jump
leads. Observe the following points:
R The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,
jump-start the vehicle using a second battery or ajump-starting device.
R Vehicles with apetrol engine: only jump-star tthe vehicle when the engine and exhaust
system are cold.
R Do not start the engine if the battery is frozen. Let the battery thaw first.
R Jump-starting may only be performed from batteries with a nominal voltage of 12 V.
R Only use jump leads that have a sufficient cross-section and insulated terminal clamps.
R If the battery is fully discharged, leave the battery that is being used to jump-start connected
for a few minutes before attempting to start. This charges the empty battery a little.
R Make sure that the two vehicles do not touch.
Make sure that:
R The jump leads are not damaged.
R Non-insulated parts of the terminal clamps do not come into contact with other metal parts
while the jump leads are connected to the battery.
R The jump leads cannot come into contact with parts such as the pulley or the fan. These
parts move when the engine is started and while it is running.
