Restraint system warning lamp
The functions of the restraint system arechecked after the ignition is switched on and atregular intervals while the engine is running.Therefore, malfunctions can be detected ingood time.
Theurestraint system warning lamp on theinstrument cluster lights up when the ignition isswitched on. It goes out no later than a few sec-onds after the vehicle is started. The compo-nents of the restraint system are in operationalreadiness.
A malfunction has occurred if theurestraintsystem warning lamp:
Rdoes not light up after the ignition is switchedon
Rdoes not go out after a few seconds with theengine running
Rlights up again while the engine is running
GWARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not deploy as
intended during an accident. This can affect
for example the Emergency Tensioning
Device or the air bag. This poses an increased
risk of injury or even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible.

If the PASSENGER AIR BAG ON indicator lamp isoff, only the PASSENGER AIR BAG OFF indicatorlamp shows the status of the front-passengerfront air bag. The PASSENGER AIR BAG OFFindicator lamp may be lit continuously or be off.
Depending on the person in the front-passengerseat, the front-passenger front air bag musteither be deactivated or enabled; see the fol-lowing points. You must make sure of this bothbefore and during a journey.
RChildren in a child restraint system:whether the front-passenger front air bag isenabled or deactivated depends on the instal-led child restraint system, and the age andsize of the child. Therefore, be sure to observethe notes on the "Occupant ClassificationSystem (OCS)" (Ypage 51) and on "Chil-dren in the vehicle" (Ypage 59). There youwill also find instructions on rearward andforward-facing child restraint systems on thefront-passenger seat.
RAll other persons:depending on the classi-fication of the person in the front-passengerseat, the front-passenger front air bag is ena-bled or deactivated (Ypage 51). Be sure toobserve the notes on "Seatbelts“ (Ypage 44) and "Air bags"(Ypage 48). There you can also find infor-mation on the correct seat position.
Seat belts
Introduction
Seat belts are the most effective means ofrestricting the movement of vehicle occupantsin the event of an accident or the vehicle rollingover. This reduces the risk of vehicle occupantscoming into contact with parts of the vehicleinterior or being ejected from the vehicle. Fur-thermore, the seat belt helps to keep the vehicle

Window curtain air bagsCare integrated intothe side of the roof frame and deployed in thearea from the A-pillar to the C-pillar.
When deployed, the window curtain air bagenhances the level of protection for the head.However, it does not protect the chest or arms.
If the restraint system control unit detects a sideimpact, the window curtain air bag is deployedon the side on which the impact occurs.
If the system determines that they can offeradditional protection to that provided by theseat belt, a window curtain air bag may bedeployed in other accident situations(Ypage 55).
Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS) cat-egorizes the person in the front-passenger seat.Depending on that result, the front-passengerfront air bag is either enabled or deactivated.
The system does not deactivate:
Rthe side impact air bag
Rthe window curtain air bag
Rthe Emergency Tensioning Devices
Requirements
To be classified correctly, the front passengermust sit:
Rwith the seat belt fastened correctly
Rin an almost upright position with their backagainst the seat backrest
Rwith their feet resting on the floor, if possible
If the front passenger does not observe theseconditions, OCS may produce a false classifica-tion, e.g. because the front passenger:
Rtransfers their weight by supporting them-selves on a vehicle armrest
Rsits in such a way that their weight is raisedfrom the seat cushion
If it is absolutely necessary to install a childrestraint system on the front-passenger seat, besure to observe the correct positioning of thechild restraint system. Never place objectsunder or behind the child restraint system, e.g. acushion. Fully retract the seat cushion length.The entire base of the child restraint system
must always rest on the seat cushion of thefront-passenger seat. The backrest of theforward-facing child restraint system must lie asflat as possible against the backrest of the front-passenger seat.
The child restraint system must not touch theroof or be subjected to a load by the headrestraint. Adjust the angle of the seat backrestand the head restraint position accordingly.
Only then can OCS be guaranteed to functioncorrectly. Always observe the child restraint sys-tem manufacturer's installation and operatinginstructions.

If the PASSENGER AIR BAG ON indicator lamp isoff, only the PASSENGER AIR BAG OFF indicatorlamp shows the status of the front-passengerfront air bag. The PASSENGER AIR BAG OFFindicator lamp may be lit continuously or be off.
If the status of the front-passenger front air bagchanges while the vehicle is in motion, an air bagdisplay message appears in the instrument clus-ter (Ypage 237). When the front-passengerseat is occupied, always pay attention to thePASSENGER AIR BAG OFF indicator lamp. Beaware of the status of the front-passenger frontair bag both before and during the journey.
GWARNING
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:
Rthe 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
Rthe front-passenger seat has been moved
back as far back as possible.
Rthe 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.
GWARNING
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 lampstays off, do not install a rearward-facing childrestraint system on the front-passenger seat.You can find more information on OCS under"Problems with the Occupant Classification Sys-tem" (Ypage 54).
GWARNING
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, in the event of an
accident, the child could:
Rcome into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
Rbe 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.
Always move the front-passenger seat as far
back as possible and fully retract the seat
cushion length. 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 downwards from the vehicle belt sash
guide. If necessary, adjust the vehicle belt
sash guide and the front-passenger seat
accordingly. Always observe the child
restraint system manufacturer's installation
instructions.

When the front-passenger seat is occupied,
always ensure that:
Rthe classification of the person in the front-
passenger seat is correct and the front-
passenger front air bag is enabled or deac-
tivated in accordance with the person in the
front-passenger seat
Rthe person is seated properly with a cor-
rectly fastened seatbelt
Rthe front-passenger seat has been moved

If the PASSENGER AIR BAG OFF indicator
lamp remains lit when it should not, the front-
passenger seat must not be used. Do not
install a child restraint system on the front-
passenger seat. Have the Occupant Classifi-
cation System (OCS) checked and repaired
immediately at a qualified specialist work-
shop.
GWARNING
Objects between the seat surface and the
child restraint system could affect OCS oper-
ation. This could result in the front-passenger
air bag not functioning as intended during an
accident. This poses an increased risk of
injury or even fatal injury.
Do not place any objects between the seat
surface and the child restraint system. 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, as far as
possible, be resting on the backrest of the
front-passenger seat. Always comply with the
child restraint system manufacturer's instal-
lation instructions.
After the self-test, the PASSENGER AIR BAG OFFor the PASSENGER AIR BAG ON indicator lampdisplays the status of the front-passenger frontair bag (Ypage 51). If the front-passenger frontair bag is enabled, the PASSENGER AIR BAG ONindicator lamp lights up for 60 seconds and thengoes out.

Important safety notes
GWARNING
If the rear seat backrests are not locked, they
could fold forwards in the event of an acci-
dent, heavy braking or sudden changes of
direction. As a result, child restraint systems
cannot perform their intended protective
function. Rear seat backrests that are not
locked can also cause additional injuries, e.g.
in the event of an accident. This poses an
increased risk of injury or even fatal injury.
Always lock rear seat backrests after instal-
ling a Top Tether belt. Observe the lock veri-
fication indicator.
If the rear seat backrest is not engaged andlocked, this will be shown in the multifunctiondisplay in the instrument cluster.
