and ETDs) impacts which exceed preset
deployment thresholds and in certain roll-
overs (window curtain air bags and ETDs).
R Never wear the shoulder belt under your
arm, across your neck or off your shoulder.
In a frontal crash, your body would move
too far forward. That would increase the
chance of head and neck injuries. The seat belt would also apply too much force to the
ribs or abdomen, which could severely
injure internal organs such as your liver or
spleen.
Adjust the seat belt so that the shoulder
section is located as close as possible to
the middle of the shoulder. It should not
touch the neck. Never pass the shoulder
portion of the seat belt under your arm. For
this purpose, you can adjust the height of
the seat belt outlet.
R Position the lap belt as low as possible on
your hips and not across the abdomen. If
the lap belt is positioned across your abdo-
men, it could cause serious injuries in a
crash.
R Never wear seat belts over rigid or breaka-
ble objects in or on your clothing, such as
eyeglasses, pens, keys etc., as these might
cause injuries.
R Make sure the seat belt is always fitted
snugly. Take special care of this when wear-
ing loose clothing.
R Never use a seat belt for more than one
person at a time. Do not fasten a seat belt
around a person and another person or
other objects at the same time.
R Seat belts should not be worn twisted. In a
crash, you would not have the full width of
the seat belt to distribute impact forces.
The twisted seat belt against your body
could cause injuries.
R Pregnant women should also always use a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible on the hips to avoid any possible pressure on
the abdomen. R
Place the seat backrest in a position that is
as upright as possible.
R Check your seat belt during travel to make
sure it is properly positioned.
R Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
R When using a seat belt to secure infant
restraints, toddler restraints, or children in
booster seats, always follow the child seat
manufacturer's instructions. G
WARNING
Do not pass seat belts over sharp edges. They
could tear.
Do not allow the seat belt to get caught in the door or in the seat adjustment mechanism.
This could damage the seat belt.
Never attempt to make modifications to seat
belts. This could impair the effectiveness of
the seat belts.
Fastening seat belts G
WARNING
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus, we strongly recommend that children be
placed in the rear seat whenever possible.
Regardless of seating position, children 12
years old and under must be seated and prop- erly secured in an appropriately sized child
restraint system or booster seat recommen-
ded for the size and weight of the child. For
additional information, see the "Children in
the vehicle" section.
A child's risk of serious or fatal injuries is sig-
nificantly increased if the child restraints are
not properly secured in the vehicle and/or the child is not properly secured in the child
restraint. Occupant safety

Belt warning for the driver and front
passenger Every time the engine is started, the
0076
seat belt warning lamp lights up for six sec-
onds. It lights up regardless of whether the
driver's and front-passenger seat belts have
already been fastened. If the driver's and
front-passenger seat belts have already been fastened, the 0076seat belt warning lamp
then goes out.
If the driver's seat belt is not fastened when
the engine is started, an additional warning
tone will sound. This warning tone stops after
a maximum of six seconds or once the driv-
er's seat belt is fastened.
If after six seconds, the driver or front
passenger have not fastened their seat belts
and the doors are closed:
R the 0076 seat belt warning lamp remains lit
as long as the driver's or front-passenger's seat belt is not fastened
and
R if a vehicle speed of 15 mph (25 km/h) is
exceeded, the 0076seat belt warning lamp
begins to flash. A warning tone also sounds
with increasing intensity for a maximum of 60 seconds or until the driver or front
passenger have fastened their seat belts.
If the driver/front passenger unfasten their
seat belt while the vehicle is in motion, the
0076 seat belt warning lamp lights up and a
warning tone sounds again.
The warning tone ceases even if the driver or
front-passenger seat belt has still not been
fastened after 60 seconds. The 0076seat belt
warning lamp stops flashing but remains illu- minated.
After the vehicle comes to a standstill, the
warning tone is reactivated. The 0076seat
belt warning lamp flashes again if the vehicle
speed exceeds 15 mph (25 km/h).
The 0076 seat belt warning lamp only goes
out if:
R both the driver and the front passenger
have fastened their seat belts.
or
R the vehicle is stationary and a door is open.

0076seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrument cluster, seat

WARNING
Pyrotechnic Emergency Tensioning Devices
that have been deployed are no longer opera- tional and are unable to perform their inten-
ded protective function. This poses an
increased risk of injury or even fatal injury.
Therefore, have pyrotechnic Emergency Ten-
sioning Devices which have been triggered
immediately replaced at a qualified specialist workshop.
! 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 Emergency Tensioning
Device could be triggered in the event of an accident. Occupant safety
55Safety Z

The front seat belts and the outer seat belts in
the rear are equipped with Emergency Ten-
sioning Devices and seat belt force limiters.
The ETDs tighten the seat belts in an accident, pulling them close against the body.
The ETDs do not correct incorrect seat posi-
tions or incorrectly fastened seat belts.
The ETDs do not pull vehicle occupants back
towards the backrest.
The ETDs can only be activated when:
R the ignition is switched on
R the restraint systems are operational; see
"0075 SRS warning lamp" (Y page 41)
R the belt tongue has engaged in the belt
buckle of the respective front seat
The ETDs on the outside seats in the rear
compartment are triggered independently of
the lock status of the seat belts.
The ETDs are triggered depending on the type
and severity of an accident:
R in the event of a head-on or rear-end colli-
sion if the vehicle decelerates or acceler-
ates rapidly in a longitudinal direction dur-
ing the initial stages of the impact.
R in the event of a side impact if the vehicle
decelerates or accelerates rapidly in a lat-
eral direction on the side opposite to the
impact.
R in certain situations where the vehicle rolls
over if the system determines that it can
provide additional protection.
If the ETDs are deployed, you will hear a bang,
and a small 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 and does not indicate that there is a fire in the vehicle. The dust might cause
some temporary breathing difficulty for peo-
ple with asthma or other breathing trouble. To avoid this, you may wish to get out of the
vehicle as soon as it is safe to do so. You can
also open the window to allow fresh air to
enter the vehicle interior. The 0075SRS warn-
ing lamp lights up. If the seat belt is also equipped with a seat
belt force limiter and this is triggered, the
force exerted by the seat belt on the vehicle
occupant is reduced.
The seat belt force limiters for the front seats
are synchronized with the front air bags,
which absorb part of the deceleration force.
This results in the force exerted on the occu- pant being distributed over a greater area. Children in the vehicle

Important safety notes G
WARNING
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommend that
children be placed in the rear seats whenever possible. Regardless of seating position, chil- dren 12 years old and under must be seated
and properly secured in an appropriate infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.
The infant or child restraint must be properly
secured with the vehicle's seat belt, the seat
belt and top tether strap, or lower anchors and
top tether strap, fully in accordance with the
child seat manufacturer's instructions.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Note the following impor-
tant information when circumstances require you to place a child in the front passenger
seat:
R Your vehicle is equipped with air bag tech-
nology designed to deactivate the front 56

passenger front air bag in your vehicle
when the system senses the weight of a
typical 12‑
month-old child or less along
with the weight of a standard appropriate
child restraint on the front passenger seat.
R For children larger than the typical
12‑month-old child, the front passenger
front air bag may or may not be activated.
Always make sure the 00730074indicator
lamp is illuminated, indicating that the front
passenger front air bag is deactivated.
R A child in a rear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates in a collision which
could occur under some circumstances,
even with the air bag technology installed in your vehicle. The only means to completely
eliminate this risk is to never place a child in a rear-facing child restraint in the front
seat. We therefore strongly recommend
that you always place a child in a rear-facing child restraint in a backseat.
R If you must install a rear-facing child
restraint on the front passenger seat
because circumstances require you to do
so, make sure the 00730074indicator
lamp is illuminated, indicating that the front passenger front air bag is deactivated.
Should the 00730074indicator lamp not
illuminate or go out while the restraint is
installed, please check installation. Period-
ically check the 00730074indicator lamp
while driving to make sure the 00730074
indicator lamp is illuminated. If the 0073
0074 indicator lamp goes out or remains
out, do not transport a child on the front
passenger seat until the system has been
repaired.
A child in a rear-facing child restraint on the front passenger seat will be seriously
injured or even killed if the front passenger front air bag inflates.
R If you have to place a child in a forward-
facing child restraint on the front passenger seat, move the seat as far back as possible, use the proper child restraint recommen-
ded for the age, size and weight of the child,
and secure child restraint with the vehicle's seat belt according to the child seat man-
ufacturer's instructions. G
WARNING
If the child restraint system is installed incor- rectly on a suitable seat, it cannot protect as
intended. The child cannot then be restrained in the event of an accident, heavy braking or
sudden changes of direction. There is an
increased risk of injury, possibly even fatal.
Make sure that you observe the child restraint
system manufacturer's installation instruc-
tions and the notes on use. Please ensure,
that the base of the child restraint system is
always resting completely on the seat cush-
ion. Never place objects, e.g. cushions, under or behind the child restraint system. Only use
child restraint systems with the original cover
designed for them. Only replace damaged
covers with genuine covers. G
WARNING
If the child restraint system is installed incor- rectly or is not secured, it can come loose in
the event of an accident, heavy braking or a
sudden change in direction. The child
restraint system could be thrown about, strik- ing vehicle occupants. There is an increased
risk of injury, possibly even fatal.
Always install child restraint systems prop-
erly, even if they are not being used. Make
sure that you observe the child restraint sys-
tem manufacturer's installation instructions. G
WARNING
Child restraint systems or their securing sys-
tems which have been damaged or subjected to a load in an accident can no longer protect
as intended. The child cannot then be
restrained in the event of an accident, heavy
braking or sudden changes of direction. There is an increased risk of injury, possibly even
fatal. Children in the vehicle

Z

Replace child restraint systems which have
been damaged or subjected to a load in an
accident as soon as possible. Have the secur- ing systems on the child restraint system
checked at a qualified specialist workshop,
before you install a child restraint system
again. G
WARNING
Infants and small children should never share a seat belt with another occupant. In the event
of an accident, they could be crushed
between the occupant and seat belt.
A child's risk of serious or fatal injuries is sig- nificantly increased if the child restraints are
not properly secured in the vehicle and/or thechild is not properly secured in the child
restraint.
Children that are too large for a child restraint
must travel in seats using normal seat belts.
Position the shoulder belt across the chest
and shoulder, not the face or neck. A booster seat may be necessary to achieve proper seat
belt positioning for children over 41 lbs
(18 kg) until they reach a height where a lap/
shoulder belt fits properly without a booster
seat.
When the child restraint is not in use, remove it from the vehicle or secure it with the seat
belt to prevent the child restraint from becom-
ing a projectile in the event of an accident. G
WARNING
If children are left unsupervised in the vehicle, they could:
R open the doors, thus endangering other
people or road users.
R get out and disrupt traffic.
R operate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
R release the parking brake.
R shifting the automatic transmission out of
park position P
R Start the engine. There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children. G
WARNING
If persons, particularly children are subjected to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle. G
WARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Chil-
dren may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight. Pro- tect it with a blanket, for example. If the childrestraint system has been exposed to direct
sunlight, let it cool down before securing the
child in it. Never leave children unattended in the vehicle.
If an infant or child is traveling in the vehicle:
R Secure the child with a child or infant seat
restraint system appropriate to the age and
weight of the child.
R Make sure that the infant or child is prop-
erly secured at all times while the vehicle is
in motion.
Mercedes-Benz recommends that you always
properly secure all infants and children with a
child or infant seat restraint system for the
trip.

LATCH-type (ISOFIX) child seat anchors
in the rear G
WARNING
LATCH-type (ISOFIX) child restraint systems
do not offer sufficient protective effect for
children whose weight is greater than 48 lbs
(22 kg) who are secured using the safety belt integrated in the child restraint system. In the
event of an accident, a child might not be
restrained correctly. This poses an increased
risk of injury or even fatal injury.
If the child weighs more than 48 lbs (22 kg),
only use LATCH-type (ISOFIX) child restraint
systems with which the child is also secured
with the vehicle seat belt. Also secure the
child restraint system with the Top Tether
belt, if available.
When installing a child restraint system, be
sure to observe the manufacturer's installa-
tion instructions and the instructions for cor- rect use of the child restraint system.
! When installing the LATCH-type (ISOFIX)
