Restraint system warning lamp
The functions of the restraint system arechecked after the ignition is switched on andat regular intervals while the engine is running.Therefore, malfunctions can be detected ingood time.
The urestraint system warning lamp onthe instrument cluster lights up when the igni-tion is switched on. It goes out no later than afew seconds after the vehicle is started. Thecomponents of the restraint system are inoperational readiness.
A malfunction has occurred if the urestraint system warning lamp:
Rdoes not light up after the ignition isswitched on
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.
PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG ON indicator lamp Cand PASSENGER AIR BAG OFF indicatorlamp Dare part of the Occupant Classifica-tion System (OCS).
The indicator lamps display the status of thefront-passenger front air bag.
RPASSENGER AIR BAG ON lights up for 60seconds, subsequently both indicator lampsare off (PASSENGER AIR BAG ON and OFF):the front-passenger front air bag is able todeploy in the event of an accident.
RPASSENGER AIR BAG OFF lights up: thefront-passenger front air bag is deactivated.It will then not be deployed in the event ofan accident.
If the PASSENGER AIR BAG ON indicator lampis off, only the PASSENGER AIR BAG OFF indi-cator lamp shows the status of the front-passenger front air bag. The PASSENGER AIRBAG OFF indicator lamp may be lit continu-ously or be off.
Depending on the person in the front-passenger seat, the front-passenger front airbag must either be deactivated or enabled;see the following points. You must make sureof this both before and during a journey.
RChildren in a child restraint system:whether the front-passenger front air bag isenabled or deactivated depends on theinstalled child restraint system, and the ageand size of the child. Therefore, be sure toobserve the notes on the "Occupant Classifi-cation System (OCS)" (Ypage 47) and on"Children in the vehicle" (Ypage 53).There you will also find instructions on rear-ward and forward-facing child restraint sys-tems on the front-passenger seat.

Belt warning for the driver and front
passenger
The vseat belt warning lamp in the instru-ment cluster is a reminder that all vehicleoccupants must wear their seat belts. It maylight up continuously or flash. In addition,there may be a warning tone.
Regardless of whether the driver's seat belthas already been fastened, the vseat beltwarning lamp lights up for six seconds eachtime the engine is started. If the front doorsare closed and the driver's or front-passengerseat belt has not been fastened, the vseatbelt warning lamp lights up again after the sixseconds. As soon as the driver's and front-passenger seat belts are fastened or a frontdoor is opened again, the vseat belt warn-ing lamp goes out.
If the driver's seat belt is not fastened afterthe engine is started, an additional warningtone will sound. The warning tone switches offafter six seconds or once the driver's seat beltis fastened.
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 warn-ing tone sounds. A warning tone also soundswith increasing intensity for 60 seconds oruntil the driver or front passenger have fas-tened their seat belts.
If the driver or front passenger unfasten theirseat belts during the journey, the seat beltwarning is activated again.
Air bags
Introduction
The installation point of an airbag can be rec-ognized by the AIRBAG marking.
An airbag complements the correctly fastenedseat belt. It is no substitute for the seat belt.When deployed, an airbag can increase theprotection provided for the respective vehicleoccupant.
Not all airbags are deployed in an accident.The various airbags work independently ofeach other (Ypage 51).
However, no system available today can com-pletely eliminate injuries and fatalities.
It is also not possible to rule out a risk of injurycaused by an airbag due to the high speed atwhich the airbag must be deployed.
Important safety notes
GWARNING
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:
Rhave fastened their seat belts correctly,
including pregnant women
Rare sitting correctly and maintain the
greatest possible distance to the air bags
Rfollow 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 airbagwhen it deploys.
RAdjust the seats properly before beginningyour journey. Always make sure that theseat is in an almost upright position. Thecenter of the head restraint must supportthe head at about eye level.
RMove the driver's and front-passenger seatsas far back as possible. The driver's seatposition must allow the vehicle to be drivensafely.
ROnly hold the steering wheel on the outside.This allows the airbag to be fully deployed.
RAlways lean against the backrest while driv-ing. Do not lean forward or lean against thedoor or side window. You may otherwise bein the deployment area of the airbags.
RAlways keep your feet in the footwell infront of the seat. Do not put your feet on thedashboard, for example. Your feet may oth-erwise be in the deployment area of the air-bag.
RFor this reason, always secure persons lessthan 5 ft (1.50 m) tall in suitable restraint

systems. Up to this height, the seat beltcannot be worn correctly.
If a child is traveling in your vehicle, alsoobserve the following notes:
RAlways secure children under twelve yearsof age and less than 5 ft (1.50m)tall in suit-able child restraint systems.
RChild restraint systems should be installedon the rear seats.
RSecure a child to the front-passenger seatonly when the front-passenger front airbagis deactivated, and then only in a rearward-facing child restraint system. The front-passenger front airbag is deactivated whenthe PASSENGER AIR BAG OFF indicatorlamp is lit continuously (Ypage 40).
RAlways observe the instructions and safetynotes on the "Occupant Classification Sys-tem (OCS)" (Ypage 47) and on "Childrenin the vehicle" (Ypage 53) in addition tothe child restraint system manufacturer'sinstallation and operating instructions.
Objects in the vehicle interior may restrictthe airbag from functioning correctly.Toavoid risks resulting from the speed of the air-bag as it deploys, vehicle occupants mustensure the following points.
Before commencing your journey, ensure that:
Rthere are no people, animals or objectsbetween the vehicle occupants and an air-bag
Rthere are no objects between the seat, doorand B-pillar
Rthere are no hard objects, e.g. coat hangers,hanging on the grab handles or coat hooks
Rno accessories, such as cup holders, areattached to the vehicle within the deploy-ment area of an airbag, e.g. to doors, sidewindows, rear side trim or side walls
Rno heavy, sharp-edged or fragile objects arein the pockets of your clothing. Store suchobjects in a suitable place
GWARNING
If you modify the cover of an air bag or affix
objects such as stickers to it, the air bag
can no longer perform its intended function.
There is an increased risk of injury.
Never modify the cover of an air bag or affix
objects to it.
GWARNING
Sensors to control the air bags are located
in the doors. Modifications or work not per-
formed correctly to the doors or door panel-
ing, as well as damaged doors, can lead to
the function of the sensors being impaired.
The air bags might therefore not function
properly anymore. Consequently, the air
bags cannot protect vehicle occupants as
they are designed to do. There is an
increased risk of injury.
Never modify the doors or parts of the
doors. Always have work on the doors or
door paneling carried out at a qualified spe-
cialist workshop.
Front air bags
!Do not place heavy objects on the front-passenger seat. This could cause the sys-tem to identify the seat as being occupied.In the event of an accident, the restraintsystems on the front-passenger side may betriggered and have to be replaced.
Driver's air bag Cdeploys in front of thesteering wheel. Front-passenger front airbag Ddeploys in front of and above the glovebox.
When deployed, the front air bags offer addi-tional head and thorax protection for the occu-pants in the front seats.
The PASSENGER AIR BAG OFF indicator lampinforms you about the status of the front-passenger front air bag (Ypage 40).
The front-passenger front air bag will onlydeploy if:
Rthe system, based on the OCS weight sen-sor readings, detects that the front-

XPress the Start/Stop button once or twice,or turn the SmartKey to position Gor Hinthe ignition lock.The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF andPASSENGER AIR BAG ON indicator lamps mustlight up simultaneously for approximately sixseconds.
The indicator lamps display the status of thefront-passenger front air bag.
RPASSENGER AIR BAG ON lights up for60 seconds, subsequently both indicatorlamps are off (PASSENGER AIR BAG ON andOFF): the front-passenger front air bag isable to deploy in the event of an accident.
RPASSENGER AIR BAG OFF lights up: thefront-passenger front air bag is deactivated.It will then not be deployed in the event ofan accident.
If the PASSENGER AIR BAG ON indicator lampis off, only the PASSENGER AIR BAG OFF indi-cator lamp shows the status of the front-passenger front air bag. The PASSENGER AIRBAG OFF indicator lamp may be lit continu-ously or be off.
If the status of the front-passenger front airbag changes while the vehicle is in motion, anair bag display message appears in the instru-ment cluster (Ypage 213). When the front-passenger seat is occupied, always pay atten-tion to the PASSENGER AIR BAG OFF indicatorlamp. Be aware of the status of the front-passenger front air bag both before and duringthe 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 exam-
ple, come into contact with the vehicle's
interior, especially 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
disabled 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
AIRBAG 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 ClassificationSystem" (Ypage 51).

result, the front-passenger front air bag iseither enabled or deactivated.
Self-check by the Occupant Classifica-
tion System (OCS)
GDANGER
If the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps do
not both light up during the self-test, the
system is malfunctioning. The front-
passenger front air bag might be triggered
unintentionally or might not be triggered at
all in the event of an accident with high
deceleration. This poses an increased risk of
injury or even fatal injury.
In this case the front-passenger seat may
not be used. Do not install a child restraint
system on the front-passenger seat. Have
the Occupant Classification System (OCS)
checked and repaired immediately at a
qualified specialist workshop.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp remains lit after the self-test, the front-
passenger front air bag is deactivated. It will
not be deployed in the event of an accident.
In this case, the front-passenger front air
bag cannot perform its intended protective
function, e.g. when a person is seated in the
front-passenger seat.
That person could, for example, come into
contact with the vehicle's interior, especially
if the person is sitting too close to the dash-
board. 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
deactivated in accordance with the per-
son in the front-passenger seat
Rthe person is seated properly with a cor-
rectly fastened seatbelt
Rthe front-passenger seat has been moved
as far back as possible
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
Classification System (OCS) checked and
repaired immediately at a qualified specialist
workshop.
GWARNING
Objects between the seat surface and the
child restraint system could affect OCS
operation. This could result in the front-
passenger air bag not functioning as inten-
ded 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 back-
rest of the front-passenger seat. Always
comply with the child restraint system man-
ufacturer's installation instructions.
After the self-test, the PASSENGER AIR BAGOFF or the PASSENGER AIR BAG ON indicatorlamp displays the status of the front-passenger front airbag (Ypage 47). If thefront-passenger front airbag is enabled, thePASSENGER AIR BAG ON indicator lamp lightsup for 60 seconds and then goes out.
If the PASSENGER AIR BAG ON indicator lampis off, only the PASSENGER AIR BAG OFF indi-cator lamp shows the status of the front-passenger front airbag. The PASSENGER AIRBAG OFF indicator lamp may be lit continu-ously or be off.

Deployment of Emergency Tension-
ing Devices and air bags
Important safety notes
GWARNING
The air bag parts are hot after an air bag has
been deployed. There is a risk of injury.
Do not touch the air bag parts. Have a
deployed air bag replaced at a qualified spe-
cialist workshop as soon as possible.
GWARNING
A deployed air bag no longer offers any pro-
tection and cannot provide the intended pro-
Occupant safety51

tection in an accident. There is an increased
risk of injury.
Have the vehicle towed to a qualified spe-
cialist workshop in order to have a deployed
air bag replaced.
It is important for your safety and that of yourpassenger to have deployed air bags replacedand to have any malfunctioning air bagsrepaired. This will help to make sure the airbags continue to perform their protective func-tion for the vehicle occupants in the event of acrash.
GWARNING
Emergency Tensioning Devices that have
deployed pyrotechnically are no longer
operational and are unable to perform their
intended protective function. This poses an
increased risk of injury or even fatal injury.
Have pyrotechnically triggered Emergency
Tensioning Devices replaced immediately at
a qualified specialist workshop.
If Emergency Tensioning Devices are triggeredor air bags are deployed, you will hear a bang,and some powder may also be released. The urestraint system warning lamp lights up.
Only in rare cases will the bang affect yourhearing. The powder that is released generallydoes not constitute a health hazard, but it maycause short-term breathing difficulties in peo-ple with asthma or other respiratory problems.Provided it is safe to do so, you should leavethe vehicle immediately or open the window inorder to prevent breathing difficulties.
Air bags and pyrotechnic Emergency Tension-ing Devices (ETDs) contain perchlorate mate-rial, which may require special handling andregard for the environment. National guide-lines must be observed during disposal. In Cal-ifornia, seewww.dtsc.ca.gov/HazardousWaste/Perchlorate/index.cfm.
Method of operation
During the first stage of a collision, therestraint system control unit evaluates impor-tant physical data relating to vehicle decelera-tion or acceleration, such as:
Rduration
Rdirection
Rintensity
Based on the evaluation of this data, therestraint system control unit triggers the Emer-gency Tensioning Devices during a head-on orrear-end collision.
An Emergency Tensioning Device can only betriggered, if:
Rthe ignition is switched on
Rthe components of the restraint system areoperational. You can find further informationunder "Restraint system warning lamp"(Ypage 40)
Rthe seat belt buckle tongue has engaged inthe belt buckle of the respective front seat
The Emergency Tensioning Devices in the rearpassenger compartment are triggered inde-pendently of the lock status of the seat belts.
If the restraint system control unit detects amore severe accident, further components ofthe restraint system are activated independ-ently of each other in certain frontal collisionsituations:
RFront air bags as well as driver's and front-passenger knee bags
RWindow curtain air bag, if the system deter-mines that deployment can offer additionalprotection to that provided by the seat belt
Depending on the person in the front-passenger seat, the front-passenger front airbag is either enabled or disabled. The front-passenger front air bag can be deployed in anaccident only if the PASSENGER AIR BAG OFFindicator lamp is off. Observe the informationon the PASSENGER AIR BAG indicator lamps(Ypage 40).
Your vehicle has two-stage front air bags.
The activation threshold of the EmergencyTensioning Devices and the air bags is deter-mined by evaluating the rate of vehicle decel-eration or acceleration which occurs at variouspoints in the vehicle. This process is pre-emp-tive in nature. Deployment should take placein good time at the start of the collision.

you install the child restraint system on a rearseat.
If it is absolutely necessary to install a childrestraint system on the front-passenger seat,always observe the instructions and safetynotes on the "Occupant Classification System(OCS)" (Ypage 47).
You can thus avoid the risks that could ariseas a result of:
Ran incorrectly categorized person in thefront-passenger seat
Rdeactivating the front passenger front airbag unintentionally
Rthe unsuitable positioning of the childrestraint system, e.g. too close to the dash-board
Rearward-facing child restraint system
If circumstances require you to secure a childin a rearward-facing child restraint system onthe front-passenger seat, always make surethat the front passenger front air bag is deacti-vated. Only if the PASSENGER AIR BAG OFFindicator lamp is lit continuously (Ypage 40),is the front passenger front air bag deactiva-ted.
Always observe the child restraint systemmanufacturer's installation and operatinginstructions.
Forward-facing child restraint system
If it is absolutely necessary to install aforward-facing child restraint system on thefront-passenger seat, always move the front-passenger seat as far back as possible. Fullyretract the seat cushion length. The entirebase of the child restraint system must alwaysrest on the seat cushion of the front-passenger seat. The backrest of the childrestraint system must lie as flat as possibleagainst the backrest of the front-passengerseat. The child restraint system must nottouch the roof or be subjected to a load by thehead restraint. Adjust the angle of the seatbackrest and the head restraint positionaccordingly. Always make sure that the shoul-der belt strap is correctly routed from the vehi-cle belt outlet to the shoulder belt guide onthe child restraint system. The shoulder beltstrap must be routed forward and down fromthe vehicle belt outlet. If necessary, adjust the
vehicle belt outlet and the front-passengerseat accordingly.
Always observe the child restraint systemmanufacturer's installation and operatinginstructions.
