Electronic control units con tain data memo ries
which can permanently or temp orarily store tech‐

component stre ss, service requirements as well
as tech nical events and malfunctions.
This information general lydocuments thest ate of
a component part, a module, a sy stem or of the
environment such as:
R operating statuses of sy stem components
(e.g. fluid le vels, battery status, tire pressure)
R status messages concerning theve hicle and
its individual components (e.g. number of
wheel revo lutions/speed, deceleration, lateral
acceleration, display of thefast ened seat

fo rex ample. The data is read out via the connec‐
tion forth e diagnostics connection in theve hicle,
which is requ ired bylaw. The respective service
network locations or third parties collect, process
and use the data. The data documents tech nical

otection pr ovided bythere stra int sy stem The
restra int sy stem includes thefo llowing com‐
ponents:
R Seat belt sy stem
R Airbags
R Child restra int sy stem
R Child seat securing sy stems
The restra int sy stem can help pr eventtheve hicle
occupants from coming into contact with parts of
th eve hicle interior in theeve nt of an accident. In
th eeve nt of an accident, there stra int sy stem can
also reduce thefo rc es towhich theve hicle occu‐
pants are subjected.
Only a seat belt which is worncor rectly can pro‐
vide the intended le vel of pr otection. Depending
on the de tected accident situation, Emer gency
Te nsioning Devices and/or airbags supplement
th e pr otection of fere dby a cor rectly wornseat
belt. Emer gency Tensioning Devices and/or air‐
bags are not depl oyed in every accident.
Ve hicles with a co-driver bench seat: the Emer‐
ge ncy Tensioning Device on the co-driver seat is
triggered whe ther or not the seat belt tongue is
engaged in the seat belt buckle.
In order forth ere stra int sy stem toprov ide the
intended le vel of pr otection, each vehicle occu‐
pant must obser vethefo llowing information:
R Fasten seat belts cor rectl y.
R Sit in an almost up right seat position with
th eir back against the seat backrest.
R Sit with their feet resting on thefloor, if possi‐
ble.
R Always secure persons under 5 ft(1.50 m)
ta ll in an additional restra int sy stem suitable
fo rth is vehicle.
Ho wever,no sy stem available today can com‐
ple tely eliminate injuries and fata lities in every
accident situation. In particular, the seat belt and
airbag general lydo not pr otect against objects
penetrating theve hicle from the outside. It is also
not possible tocomple tely rule out therisk of
injury caused bythe airbag deploying. Limited pr

Have there stra int sy stem checked and
re paired immediately at a qualified spe‐
cialist workshop. Fu
nction of there stra int sy stem in an acci‐
dent How
there stra int sy stem works is de term ined by
th e se verity of the impact de tected and the type
of accident anticipated:
R Frontal impact
R Rear impact
R Side impact
R Rollover
The activation thre sholds forth e components of
th ere stra int sy stem are de term ined based on the
ev aluation of the sensor values measured at vari‐
ous points in theve hicle. This process is pre-
em ptive in nature. The triggering/deployment of
th e components of there stra int sy stem should
ta ke place in good time at thest art of the colli‐
sion.
Fa ctors whi chcan only be seen and measured
af te r a collision has occur red cann otplay a deci‐
sive role in airbag deployment. Nordothey pro‐
vide an indication of airbag deployment.
The vehicle may be deformed significantly with‐
out an airbag being deplo yed. This is the case if
only parts which are relatively easily deformed
are af fected and thera te ofvehicle deceleration
is not high. Con versely, an airbag may be
deplo yedev en though theve hicle suf fers only
minor deformation. If very rigid vehicle parts such
as longitudinal members are hit, forex ample, this
may result in suf ficiently high le vels of vehicle
deceleration.
Depending on the de tected deployment situation,
th e components of there stra int sy stem can be
activated or deplo yed independently of each
ot her:
R Emer gency Tensioning Device: frontal impact,
re ar impact, side impact 1)
,ro llo ver
R Driver's airbag, co-d rive r airbag: frontal
impact
R Side airbag: side impact
R Window cur tain airbag: side impact, rollo ver,
frontal impact

airbag or window cur tain airbag. &
WARNING Risk of bu rns from hot air bag
components
The air bag parts are hot af ter an air bag has
been depl oyed. #
Do not touch the air bag parts. #
Have a deplo yed air bag replaced at a
qu alified specialist workshop as soon as
possible. Fo
ryo ur saf ety and that of your passengers, it is
re commended that you ha vetheve hicle towe dto
a qu alified specialist workshop af ter an accident.
Ta ke this into account, particular lyif an Emer‐
ge ncy Tensioning Device has been trig gered or an
airbag has been deplo yed.
If th e Emer gency Tensioning Devices are trig‐
ge red or an airbag is deplo yed, you will hear a
bang, and a small amount of powder may also be
re leased:
R The bang will not general lyaffect your hear‐
ing.
R Ingeneral, the powder released is not hazard‐
ous tohealth but may cause short-term
breathing dif ficulties topersons suf fering
from as thma or other pulmonary conditions.
Pr ov ided it is safe todo so, lea vetheve hicle
immediately or open the window in order to

WARNING Risk of inju ryor death due to
incor rect seat position
If yo u deviate from the cor rect seat position,
th e airbag cann otper form its intended pro‐
te ctive function and deployment may even
cause fur ther injuries.
In order toavo idrisks, each vehicle occupant
must alw ays make sure of thefo llowing:
R Fasten seat belts cor rectly. Pregnant
wo men must take particular care to
ensure that the lap belt ne ver lies across
th e abdomen.
R Adopt the cor rect seat position and keep
as faraw ay as possible from the airbags.
R Obser vethefo llowing information. #
Always make sure that there are no
objects between the airbag and vehicle
occupant. To
avo idtherisks resulting from the deployment
of an airbag, each vehicle occupant must obser ve
th efo llowing information in particular:
R Before starting your journe y,adjust your seat
cor rectl y;bo th th e driver's and co-driver seat
should be mo ved as far back as possible.
When doing so, alw ays obser vethe informa‐
tion on the cor rect driver's seat position
(/ page 64).
R Only hold thesteering wheel bythesteering
wheel rim. This allows the airbag tobe fully
deplo yed.
R Always lean against the seat backrest when
th eve hicle is in motion. Do not lean forw ards
or against the door or side windo w.You may Occupant saf

of the airbag.
R Ifch ildren are tr aveling in theve hicle, obser ve
th e additional no tes (/ page37).
R Alwaysstow and secure objects cor rectly.
Objects in theve hicle interior may pr event an air‐
bag from functioning cor rectl y.Each vehicle
occupant must alw ays make sure of thefo llowing
in particular:
R There are no people, animals or objects
between theve hicle occupants and an airbag.
R There are no objects between the seat, door
and door pillar (B-pillar).
R There are no hard objects, e.g. coat hangers,
hanging on the grab handles or coat hooks.
R There are no accessory parts, such as mobile
navigation devices, mobile phones or cup
holders, attached totheve hicle within the
deployment area of an airbag, e.g. on the
cockpit, on the door, on the side window or
on the side wall trim.
In addition, no connecting cables, tensioning
st ra ps or retaining stra ps must be routed or
attached totheve hicle within the deployment
area of an airbag. Alw ays comply with the
accesso rymanufacturer's ins tallation instruc‐

places for ins tallation.
R There are no heavy, sharp-edged or fragile
objects in the poc kets of your clo thing. Store
such objects in a suitable place. Limited pr
