All seat belts except the driver's seat belt are
equipped with a special seat belt retractor to
securely fasten child restraint systems in the
vehicle. Further information can be found under "Special seat belt retractor" (Y page 58).Releasing seat belts !
Make sure that the seat belt is fully rolled up.
Otherwise, the seat belt or belt tongue will be
trapped in the door or in the seat mechanism. This could damage the door, the door trim
panel and the seat belt. Damaged seat belts
can no longer fulfill their protective function
and must be replaced. Visit a qualified spe-
cialist workshop.
X Press the release button in the belt buckle,
hold the belt tongue firmly and guide the belt
back.
Seat belt adjustment The belt adjustment is a convenience function
integrated into PRE-SAFE
®
. With this function,
the driver's and front-passenger seat belts are
adjusted to the upper body of the vehicle occu-
pant.
The seat belt strap will slightly tighten if:
R the belt tongue is inserted into the buckle and
R the ignition is switched on
The seat belt adjustment will apply a certain
tightening force if any slack is detected between
the vehicle occupant and the seat belt. Do not
grab hold of the seat belt.
The belt adjustment can be switched on and off using the on-board computer (Y page 219).
Belt warning for the driver and front
passenger The
0076 seat belt warning lamp in the instru-
ment cluster is a reminder that all vehicle occu-
pants must wear their seat belts. It may light up
continuously or flash. In addition, there may be
a warning tone.
Regardless of whether the driver's seat belt has
already been fastened, the 0076seat belt warn-
ing lamp lights up for six seconds each time the
engine is started. If the front doors are closed
and the driver's or front-passenger seat belt has not been fastened, the 0076seat belt warning
lamp lights up again after the six seconds. As
soon as the driver's and front-passenger seat
belts are fastened or a front door is opened
again, the 0076seat belt warning lamp goes out.
If the driver's seat belt is not fastened after the engine is started, an additional warning tone will
sound. The warning tone switches off after six 46
Occupant safetySafety

seconds or once the driver's seat belt is fas-
tened.
If the vehicle's speed exceeds 15 mph
(25 km/h) once and the driver's and front-
passenger seat belts are not fastened, a warning
tone sounds. A warning tone also sounds with
increasing intensity for 60 seconds or until the
driver or front passenger have fastened their
seat belts.
If the driver or front passenger unfasten their
seat belts during the journey, the seat belt warn- ing is activated again. Air bags
Introduction The installation point of an air bag can be rec-
ognized by the AIRBAG marking.
An air bag complements the correctly fastened
seat belt. It is no substitute for the seat belt.
When deployed, an air bag can increase the pro-
tection provided for the respective vehicle occu-
pant.
Not all air bags are deployed in an accident. The
different air bag systems function independ-
ently from one another (Y page 54).
However, no system available today can com-
pletely eliminate injuries and fatalities.
It is also not possible to rule out a risk of injury
caused by an air bag due to the high speed at
which the air bag must be deployed.
Important safety notes G
WARNING
If you do not sit in the correct seat position,
the air bag cannot protect as intended and
could even cause additional injury when
deployed. This poses an increased risk of
injury or even fatal injury.
To avoid hazardous situations, always make
sure that all of the vehicle's occupants:
R have fastened their seat belts correctly,
including pregnant women
R are sitting correctly and maintain the great-
est possible distance to the air bags
R follow the following instructions Always make sure that there are no objects
between the air bag and the vehicle's occu-
pants.
All vehicle occupants must observe the follow-
ing notes to avoid risks posed by the air bag
when it deploys.
R Adjust the seats properly before beginning
your journey. Always make sure that the seat
is in an almost upright position. The center of the head restraint must support the head at
about eye level.
R Move the driver's and front-passenger seats
as far back as possible. The driver's seat posi- tion must allow the vehicle to be driven safely.
R Only hold the steering wheel on the outside.
This allows the air bag to be fully deployed.
R Always lean against the backrest while driv-
ing. Do not lean forward or lean against the
door or side window. You may otherwise be in the deployment area of the air bags.
R Always keep your feet in the footwell in front
of the seat. Do not put your feet on the dash-
board, for example. Your feet may otherwise
be in the deployment area of the air bag.
R For this reason, always secure persons less
than 5 ft (1.50 m) tall in suitable restraint sys-
tems. Up to this height, the seat belt cannot
be worn correctly.
If a child is traveling in your vehicle, also
observe the following notes:
R Always secure children under twelve years of
age and less than 5 ft (1.50 m)tall in suitable
child restraint systems.
R Child restraint systems should be installed on
the rear seats.
R Secure a child to the front-passenger seat
only when the front-passenger front air bag is
deactivated, and then only in a rearward-
facing child restraint system. The front-
passenger front air bag is deactivated when
the PASSENGER AIR BAG OFF indicator lamp
is lit continuously (Y page 43).
R Always observe the instructions and safety
notes on the "Occupant Classification System
(OCS)" (Y page 49) and on "Children in the
vehicle" (Y page 57) in addition to the child
restraint system manufacturer's installation
and operating instructions.
Objects in the vehicle interior may restrict
the air bag from functioning correctly. To
avoid risks resulting from the speed of the air Occupant safety

G
WARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag is disabled. It will not be deployed in the event of
an accident and cannot perform its intended
protective function. A person in the front-
passenger seat could then, for example, come
into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
always ensure that:
R the classification of the person in the front-
passenger seat is correct and the front-
passenger front air bag is enabled or disa-
bled in accordance with the person in the
front-passenger seat
R the front-passenger seat has been moved
back as far back as possible.
R the person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front air bag is correct. G
WARNING
If you secure a child in a rearward-facing child
restraint system on the front-passenger seat
and the PASSENGER AIR BAG OFF indicator
lamp is off, the front-passenger front air bag
can deploy in the event of an accident. The
child could be struck by the air bag. This poses an increased risk of injury or even fatal injury.
Make sure that the front-passenger front air
bag has been deactivated. The PASSENGER
AIR BAG OFF indicator lamp must be lit.
NEVER use a rearward-facing child restraint
on a seat protected by an ACTIVE FRONT AIR- BAG in front of it; DEATH or SERIOUS INJURY
to the child can occur.
If the PASSENGER AIR BAG OFF indicator lamp
stays off, do not install a rearward-facing child
restraint system on the front-passenger seat.
You can find more information on OCS under
"Problems with the Occupant Classification Sys-
tem" (Y page 53). G
WARNING
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat too close to the dashboard, the child could, in the
event of an accident:
R come into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
R be struck by the air bag if the PASSENGER
AIR BAG OFF indicator lamp is off
This poses an increased risk of injury or even
fatal injury.
Move the front-passenger seat as far back as possible. Always make sure that the shoulder
belt strap is correctly routed from the vehicle
belt sash guide to the shoulder belt guide on
the child restraint system. The shoulder belt
strap must be routed forwards and down-
wards from the vehicle belt sash guide. If nec- essary, adjust the vehicle belt sash guide and
the front-passenger seat accordingly. Always
observe the child restraint system manufac-
turer's installation instructions.
If OCS determines that:
R The front-passenger seat is unoccupied, the
PASSENGER AIR BAG OFF indicator lamp
lights up after the self-test and remains lit.
This indicates that the front-passenger front
air bag is deactivated.
R The front-passenger seat is occupied by a
child of up to twelve months old, in a standard
child restraint system, the PASSENGER AIR
BAG OFF indicator lamp lights up after the
self-test and remains lit. This indicates that
the front-passenger front air bag is deactiva-
ted.
But even in the case of a twelve-month-old
child, in a standard child restraint system, the
PASSENGER AIR BAG OFF indicator lamp can
go out after the self-test. This indicates that
the front-passenger front air bag is activated. The result of the classification is dependent
on, among other factors, the child restraint
system and the child's stature. It is recom-
mended that you install the child restraint
system on a suitable rear seat. Occupant safety

Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install Children in the vehicle
57Safety Z

a child restraint system on a rear seat. Children
are generally better protected there.
If a child younger than twelve years old and
under 5 ft (1.50 m) in height is traveling in the
vehicle:
R always secure the child in a child restraint
system suitable for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child.
R be sure to observe the instructions and safety
notes in this section in addition to the child
restraint system manufacturer's installation
instructions.
R always observe the instructions and safety
notes on the "Occupant classification system (OCS)". (Y page 49) G
WARNING
If you leave children unsupervised in the vehi- cle, they could set it in motion by, for example:
R release the parking brake.
R shift the automatic transmission out of the
parking position P.
R start the engine.
In addition, they may operate vehicle equip-
ment and become trapped. 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 unsupervised in the vehicle. 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 child
restraint system has been exposed to direct
sunlight, let it cool down before securing the
child in it. Never leave children unattended in the vehicle.
Always ensure that all vehicle occupants have
their seat belts fastened correctly and are sitting properly. Particular attention must be paid to
children.
Observe the safety notes on the seat belt
(Y page 44) and the notes on correct use of seat
belts (Y page 45).
A booster seat may be necessary to achieve
proper seat belt positioning for children over
40 lbs (18 kg) until they reach a height where a
three-point seat belt can be properly fastened
without a booster seat. Special seatbelt retractor
G
WARNING
If the seat belt is released while driving, the
child restraint system will no longer be
secured properly. The special seat belt retrac- tor is disabled and the inertia real draws in a
portion of the seat belt. The seat belt cannot
be immediately refastened. There is an
increased risk of injury, possibly even fatal.
Stop the vehicle immediately, paying atten-
tion to road and traffic conditions. Reactivate
the special seat belt retractor and secure the
child restraint system properly.
All seat belts in the vehicle, except the driver's
seat belt, are equipped with a special seat belt
retractor. When activated, the special seat belt

R the District of Columbia
R all Canadian provinces
If you install a rearward-facing child restraint
system on the center rear seat, the rear arm rest must be folded back as far as possible.
You can obtain further information about the
correct child restraint system from any author-
ized Mercedes-Benz Center. 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.
You will find further information on stowing
objects, luggage or loads under "Loading guide-
lines" (Y page 272). 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.
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.
The securing systems of child restraint systems
are:
R the seat belt system
R the LATCH-type (ISOFIX) securing rings
R the Top Tether anchorages
If it is absolutely necessary to carry a child on
the front passenger seat, be sure to observe the information on the "Occupant Classification
System (OCS)" (Y page 49). There you will also
find information on disabling the front
passenger front air bag. Children in the vehicle
59Safety Z

All child restraint systems must meet the fol-
lowing standards:
R U.S. Federal Motor Vehicle Safety Standards
213 and 225
R Canadian Motor Vehicle Safety Standards
213 and 210.2
Confirmation that the child restraint system cor- responds to the standards can be found on an
instruction label on the child restraint system.
This confirmation can also be found in the instal-
lation instructions that are included with the
child restraint system.
Observe the warning labels in the vehicle inte-
rior and on the child restraint system. LATCH-type (ISOFIX) child seat secur-
ing system G
WARNING
For LATCH-type (ISOFIX) child restraint sys-
tems in which the child is secured using the
safety belt integrated in the child restraint
system, the maximum permissible weight of
the child and child restraint system together
is 73 lbs (33 kg).
If the child and the child restraint system
together weigh more than 73 lbs (33 kg), the
LATCH-type (ISOFIX) child restraint system
with integrated safety belt no longer offers
sufficient protection. The LATCH-type (ISO-
FIX) child seat securing system may be over-
loaded, and the child may not be restrained in
an accident, for example. This poses an
increased risk of injury or even fatal injury.
If the child and the child restraint system
together weigh more than 73 lb s(33 kg), use
only a LATCH-type (ISOFIX) child restraint sys-
tem in which the child is also secured with the vehicle seat belt. Also secure the child
restraint system with the Top Tether belt, if
available.
Regularly check that the permissible gross
weight of the child together with the child
restraint system is still maintained.
Always comply with the manufacturer's instal-
lation and operating instructions for the child
restraint system used. Before every trip, make sure that the LATCH-
type (ISOFIX) child restraint system is engaged
correctly in both LATCH-type (ISOFIX) securing
rings
! When installing the child restraint system,
make sure that the seat belt for the middle
seat does not get trapped. The seat belt could
otherwise be damaged. X
Install the LATCH-type (ISOFIX) child restraint
system on both LATCH-type (ISOFIX) securing
rings 0043.
LATCH-type (ISOFIX) is a standardized securing system for specially designed child restraint
systems on the rear seats. LATCH-type (ISOFIX)
securing rings for two LATCH-type (ISOFIX) child restraint systems are installed on the left and
right of the rear seats.
Non-LATCH-type (ISOFIX) child seats may also
be used and can be installed using the vehicle's seat belt system. Install the child seat according
to the manufacturer's instructions. Top Tether
Introduction Top Tether provides an additional connection
between the child restraint system secured with
a LATCH-type (ISOFIX) system and the vehicle.
This helps reduce the risk of injury even further.
If the child restraint system is equipped with a
Top Tether belt, this should always be used.
Important safety notes G
WARNING

passenger seat
General notes Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install the child restraint system on a rear seat.
If it is absolutely necessary to install a child
restraint system on the front-passenger seat,
always observe the instructions and safety
notes on the "Occupant Classification System
(OCS)" (Y page 49).
You can thus avoid the risks that could arise as a result of:
R an incorrectly categorized person in the front-
passenger seat
R deactivating the front passenger front air bag
unintentionally
R the unsuitable positioning of the child
restraint system, e.g. too close to the dash-
