Depending on the person in the front-
passenger seat, the front-passenger front air
bag must either be deactivated or enabled;
see the following points. You must make sure of this both before and during a journey.
R Children in a child restraint system:
whether the front-passenger front air bag is
enabled or deactivated depends on the
installed child restraint system, and the age and size of the child. Therefore, be sure to
observe the notes on the "Occupant Clas-
sification System (OCS)" ( Ypage 47) and
on "Children in the vehicle" ( Ypage 54).
There you will also find instructions on rear-
ward and forward-facing child restraint sys- tems on the front-passenger seat.
R All other persons: depending on the clas-
sification of the person in the front-
passenger seat, the front-passenger front
air bag is enabled or deactivated( Y page 47). Be sure to observe the notes
on "Seat belts“ ( Ypage 40) and "Air bags"
( Y page 44). There you can also find infor-
mation on the correct seat position.
Seat belts
Introduction
Seat belts are the most effective means of
restricting the movement of vehicle occu-
pants in the event of an accident or the vehi-
cle rolling over. This reduces the risk of vehi- cle occupants coming into contact with parts
of the vehicle interior or being ejected from
the vehicle. Furthermore, the seat belt helps
to keep the vehicle occupant in the best posi- tion in relation to the air bag.
The seat belt system comprises:
R Seat belts
R Emergency Tensioning Devices for the
front seat belts and the outer seat belts in
the rear
R Seat belt force limiters for the front seat
belts and the outer seat belts in the rear If the seat belt is pulled out of the belt outlet
quickly or with a jerky movement, the belt
retractor locks. The belt strap cannot be
extracted any further.
The Emergency Tensioning Device tightens
the seat belt in an accident, pulling the belt
close against the body. However it does not
pull the vehicle occupant back in the directionof the backrest.
The Emergency Tensioning Device does not
correct an incorrect seat position or the rout-
ing of an incorrectly fastened seat belt.
When triggered, a seat belt force limiter helps
to reduce the force exerted by the seat belt on the vehicle occupant.
The seat belt force limiters for the front seats
are synchronized with the front air bags,
which absorb part of the deceleration force.
This can reduce the force exerted on the vehi-
cle occupants during an accident.
!If the front-passenger seat is unoccupied,
do not insert the belt tongue into the buckle of the front-passenger seat. This may oth-
erwise lead to the triggering of the Emer-
gency Tensioning Device in the event of an accident, which will then need to be
replaced.
Important safety notes
The use of seat belts and child restraint sys-
tems is required by law in:
R all 50 states
R the U.S. territories
R the District of Columbia
R all Canadian provinces
Even where this is not required by law, all
vehicle occupants should correctly fasten
their seat belts before starting the journey.
GWARNING
If the seat belt is incorrectly fastened, it can-
not protect as intended. Furthermore, an
incorrectly fastened seat belt can cause addi- tional injury, for example, in an accident, dur-
ing braking or when abruptly changing direc-
40Occupant safety
Safety

However, it does not protect the chest or
arms.
In the event of a side impact, the window cur-
tain air bag is deployed on the side on which
the impact occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, a window curtain air bag may be
deployed in other accident situations( Y page 52).
Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS)
categorizes the person in the front-passenger
seat. Depending on that result, the front-
passenger front air bag is either enabled or
deactivated.
The system does not deactivate: R the side impact air bag
R the window curtain air bag
R the Emergency Tensioning Devices
Prerequisites
To be classified correctly, the front passenger
must sit:
R with the seat belt fastened correctly
R in an almost upright position with their
back against the seat backrest
R with their feet resting on the floor, if possi-
ble
If the front passenger does not observe these
conditions, OCS may produce a false classi-
fication, e.g. because the front passenger:
R transfers their weight by supporting them-
selves on a vehicle armrest
R sits in such a way that their weight is raised
from the seat cushion
If it is absolutely necessary to install a child
restraint system on the front-passenger seat,
be sure to observe the correct positioning of the child restraint system. Never place
objects under or behind the child restraint
system, e.g. cushions. The entire base of the
child restraint system must always rest on the
seat cushion of the front-passenger seat. The
backrest of the forward-facing child restraint system must lie as flat as possible against the
backrest of the front-passenger seat.
The child restraint system must not touch the
roof or be subjected to a load by the head
restraint. Adjust the angle of the seat back-
rest and the head restraint position accord-
ingly.
Only then can OCS be guaranteed to function correctly. Always observe the child restraint
system manufacturer's installation instruc-tions.
Operation of Occupant Classification
System (OCS)
:PASSENGER AIR BAG OFF indicator lamp
;PASSENGER AIR BAG ON indicator lamp
The indicator lamps inform you whether the
front-passenger front air bag is deactivated or
enabled.
X Press the Start/Stop button once or twice,
or turn the key to position 1or 2in the
ignition lock.
The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps
must light up simultaneously for approx-
imately six second s.

GWARNING
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
guidelines" ( Ypage 248).
GWARNING
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 sys-
tems 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 Classifica-
tion System (OCS)" ( Ypage 47). There you
will also find information on deactivating the
front-passenger front air bag. All child restraint systems must meet the fol-
lowing standards:
R U.S. Federal Motor Vehicle Safety Stand-
ards 213 and 225
R Canadian Motor Vehicle Safety Standards
213 and 210.2
Confirmation that the child restraint system
corresponds to the standards can be found
on an instruction label on the child restraint
system. This confirmation can also be found
in the installation instructions that are inclu-
ded 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
GWARNING
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.
Always comply with the manufacturer's
installation 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 (ISO-
FIX) 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.
