Depending on the person in the front-
passenger seat, the front-passenger front air
bag must either be disabled 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)" (Y page 53) and
on "Children in the vehicle" (Y page 61).
There you will also find instructions on
backwards- and forwards-facing child
restraint systems 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 53). Be sure to observe the notes
on "Seat belts“ (Y page 46) and "Air bags"
(Y page 50). There you can also find infor-
mation on the correct seat position. Seat belts
Introduction A correctly fastened seat belt is the most
effective means of restraining the movement
of vehicle occupants in the event of an acci-
dent or overturn. This reduces the risk of
vehicle occupants coming into contact with
parts of the vehicle interior or being thrown
from the vehicle. Furthermore, the seat belt
helps to keep the vehicle occupants in the
best position in relation to the air bag.
The seat belt system consists of:
R Seat belts
R Emergency Tensioning Devices for the
front seat belts and the outer seat belts in
the rear compartment
R Belt force limiters If the seat belt is pulled quickly or suddenly
from the belt sash guide, the inertia reel
locks. The belt strap cannot be pulled out fur-
ther.
Emergency Tensioning Devices tighten the
seat belts in an accident, pulling them close
against the occupant's body. They do not,
however, pull vehicle occupants back
towards the backrest.
Emergency Tensioning Devices do not cor-
rect an incorrect seat position or incorrectly
worn seat belts.
When activated, the belt force limiters reduce
the force exerted by the seat belt on the vehi-
cle occupants.
The belt force limiters for the front seats are
synchronized with the front air bags, which
absorb part of the deceleration force. This
makes it possible to reduce the forces to
which vehicle occupants are subjected 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 anaccident, 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. G
WARNING
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- 46
Occupant safetySafety

When deployed, the window curtain air bag
offers additional protection for the head.
However, it does not protect your 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 window curtain air bag deployment can offer additional pro-
tection to that provided by the seat belt, a
window curtain air bag may deploy in other
accident situations (Y page 58).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
In the following situation, the side impact air
bag and Emergency Tensioning Device are
disabled: the OCS system detects that the
front-passenger seat is occupied, but the seat belt tongue is not inserted in the belt buckle
of the front-passenger seat.
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 forwards-facing child restraint system must, as far as possible, be resting on
the backrest of the front-passenger seat.
The child restraint system must not touch the roof or be put under strain 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.

You will find further information on stowing
objects, luggage or loads under "Loading
guidelines" (Y page 334). 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.
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)" (Y page 53). 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 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.
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. 0043
