Data stored in the vehicle
Data storage
Aw ide range of electronic components in your
vehicle contain data memories.
These data memories temporarily or perma-
nently store technical information about:
Rthe vehicle's operating state
Rincidents
Rmalfunctions
In general, this technical information docu-
mentst he state of acomponent, amodule, a
system or the surroundings.
These include, for example:
Roperating conditions of system components,
e.g. fluid levels
Rthe vehicle's status messages and those of its
individual components, e.g. number of wheel
revolutions/speed, deceleration in move-
ment,l ateral acceleration, accelerator pedal
position
Rmalfunction sand defects in important system
components, e.g. lights, brakes
Rvehicle reactionsa nd operating conditions in
special driving situations, e.g. air bag deploy-
ment,i ntervention of stability control sys-
tems
Rambient conditions, e.g. outside temperature
This data is of an exclusively technical nature
and can be used to:
Rassist in recognizing and rectifying malfunc-
tions and defects
Ranalyze vehicle functions, e.g. after an acci-
dent
Roptimize vehicle functions
The data cannot be used to trace the vehicle's
movements.
When your vehicle is serviced, technical infor-
mation can be read from the event data memory
and malfunction data memory.
Services include, for example:
Rrepair services
Rservice processes
Rwarranties
Rquality assurance
The vehicle is read out by employees of the ser-
vice network (including the manufacturer) using special diagnostic testers. More detailed infor-

RPASSENGER AIR BAG ON lights up for 60 sec-
onds ,sub sequently both indicator lamps are
off (PASSENGER AIR BAG ON and OFF):t he

indicator lamp may be li tcontinuously or be off.
Depending on the person in the front-passenger
seat, the front-passenger front ai rbag must
either be deactivated or enabled; see the fol-
lowing points. Yo umustm ake sure of this both
before and during ajourney.
RChildreninac hild restraintsystem:
whethert he front-passenger front ai rbag is
enabled or deactivated depends on the instal- le dc hild restraint system, and the ag eand
size of the child .Therefore, be sure to observe
the notes on the "Occupant Classification
System (OCS)" (
Ypage 47 )and on "Chil-
dre nint he vehicle" (Ypage 54). There you
will also find instructions on rearward and
forward-facing child restraint systems on the
front-passenger seat.
RAl lo the rpersons: depending on the classi-
fication of the person in the front-passenger
seat, the front-passenger front ai rbag is ena-

Infants and childrenmust never travel sitting
on the lap of avehicle occupant. In the event
of an accident, they could be crushed
between the vehicle occupant and seat belt.
Robjects are never secured with aseat belt if
the seat belt is also being used by one of the
vehicle's occupants
Also ensure that there are never objects
between aperson and the seat, e.g. cushions.
Seat belts are only intended to secure and
restrain vehicle occupants. Alway sobserve the
"Loading guidelines" for securing objects, lug-
gage or loads(
Ypage 237).
Fastening and adjusting the seat belts
Observe the safety notes on the seat belt
(Ypage 42) and the notes on correct use of seat
belts (Ypage 43).

GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front ai rbag is
disabled. It will not be deploye dinthe event of
an accident and canno tperform its intended
protectiv efunction. Aperson in the front-
passenger seatc ould then, for example, come
into contact with the vehicle's interior, espe-
ciall yift he person is sitting too close to the
dashboard. Thisp oses an increased ris kof
injury or evenf atalinjury.
Whent he front-passenger seati soccupied,
always ensure that:
Rthe classification of the person in the front- passenger seati scorrect and the front-

Safety

passenger frontair 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
fronta ir bag is correct.
GWARNING
If you secure achild in arearward-facing child
restraint system on the front-passenger seat
and the PASSENGER AIR BAGO FF indicator
lamp is off, the front-passenger fronta ir 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 fronta ir
bag has been deactivated. The PASSENGER
AIR BAGO FF indicator lamp must be lit.
NEVER use arearward-facing child restraint
on aseat protected by an ACTIVE FRONT AIR-
BAGinf rontofit; DEATH or SERIOUS INJURY
to the child can occur.
If the PASSENGER AIR BAGO FF indicator lamp
stays off, do not install arearward-facing child
restraint system on the front-passenger seat.
You can find more information on OCS under
"Problems with the Occupant Classification Sys-
tem" (
Ypage 51).
GWARNING
If you secure achild in aforward-facingc hild
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 int ocontact with the vehicle's inte-
rior if the PASSENGER AIR BAGO FF indi-
cator lamp is lit, for example
Rbe struck by the air bag if the PASSENGER
AIR BAGO FF 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.
If OCS determines that:
RThe front-passenger seat is unoccupied, the
PASSENGER AIR BAGO FF indicator lamp
lights up after the system self-test and
remains lit. This indicates that the front-
passenger fronta ir bag is deactivated.
RThe front-passenger seat is occupied by a
child of up to twelve months old, in astandard
child restraint system, the PASSENGER AIR
BAGO FF indicator lamp lights up after the
system self-test and remains lit. This indi-
cates that the front-passenger fronta ir bag is
deactivated.
But even in the case of atwelve-month-old
child, in astandard child restraint system, the
PASSENGER AIR BAGO FF indicator lamp can
go out after the system self-test. This indi-
cates that the front-passenger fronta ir bag is
activated. The result of the classification is
dependen ton, among other factors, the child
restraint system and the child's stature. It is
recommended that you install the child
restraint system on asuitable rear seat.
RThe front-passenger seat is occupied by a
person of smaller stature (e.g. ateenager or
small adult), the PASSENGER AIR BAGO FF
indicator lamp lights up and remains lit after
the system self-test dependin gonthe result
of the classification or, alternatively, goes out.

GWARNING
Objects between the seat surface and the
child restraint system coul daffect OCS oper-
ation. This coul dresult 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
alway srest on the seat cushion of the front-
passenger seat. The backrest of the forward-
facing child restraint system must, as far as
possible,ber esting on the backrest of the
front-passenge rseat. Always comply with the
child restraint system manufacturer's instal-
lation instructions. After the system self-test, the PASSENGER AIR
BAG OFF or PASSENGER AIR BAG ON indicator
lamp display

XMake sure that the entire base of the child restraint system rests 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. If necessary,
adjust the position of the front-passenger seat.
XMake sure that the seat cushion length is fully retracted.
XWhen installing the child restraint system, make sure that the seat
belt is tight. Do not pull the seat belt tight using the front-passenger seat adjustment .This could result in the seat belt and the child
restraint system being pulled too tightly.
XCheck for correct installation of the child restraint system.
Make sure that the head restraint does not apply aload to the child

ingly.
XMake sure that no object sare applying additional weight onto the
seat.
XIf the PASSENGER AIR BAG OFF indicator lamp remains off and/or
