These data memories temporarily or perma-
nently store technical information about:
Rvehicle's operating state
Rincidents
Rmalfunctions
In general, this technical information docu-
ments the state of a component, a module, 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, lateral acceleration, accelerator pedal
position
Rmalfunctions and defects in important system
components, e.g. lights, brakes
Rvehicle reactions and operating conditions in
special driving situations, e.g. air bag deploy-
ment, intervention 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 function
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-
mation is obtained from it, if required.
After a malfunction has been rectified, the infor-
mation is deleted from the malfunction memory or is continually overwritten.
When operating the vehicle, situations are con-
ceivable in which this technical data, in connec- tion with other information (if necessary, under
consultation with an authorized expert), could
be traced to a person.
Examples include:
Raccident reports
Rdamage to the vehicle
Rwitness statements
Further additional functions that have been con-
tractually agreed upon with the customer allow
certain vehicle data to be conveyed by the vehi-
cle as well. The additional functions include, for
example, vehicle location in case of an emer-
gency.
COMAND/mbrace
If the vehicle is equipped with COMAND or
mbrace, additional data about the vehicle's
operation, the use of the vehicle in certain sit-
uations, and the location of the vehicle may be
compiled through COMAND or the mbrace sys-
tem.
For additional information please refer to the
COMAND User Manual or the Digital Operator's
Manual and/or the mbrace Terms and Condi-
tions.
Event data recorders
This vehicle is equipped with an event data
recorder (EDR). This vehicle is equipped with an
event data recorder (EDR). The main purpose of
an EDR is to record, in certain crash or near
crash-like situations, such as an air bag deploy-
ment or hitting a road obstacle, data that will
assist in understanding how a vehicle's systems
performed. The EDR is designed to record data
related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds
or less.
The EDR in this vehicle is designed to record
such data as:
RHow various systems in your vehicle were
operating
RWhether or not the driver and passenger
safety belts were buckled/fastened
RHow far (if at all) the driver was depressing theaccelerator and/or brake pedal and
RHow fast the vehicle was traveling.

Introduction to the restraint system
The restrain tsystem can reduce th eris kof vehi-

th eair bags that increas eprotection in that par-
ticular acciden tsituation are deployed. How-

PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG ON indicator lamp:and
PASSENGER AIR BAG OFF indicator lamp ;are
part of the Occupant Classification System
(OCS).
The indicator lamps display the status of the
front-passenger front air bag.
RPASSENGER AIR BAG ON lights up: the front-
passenger front air bag is enabled. If, in the
event of an accident, all deployment criteria
are met, the front-passenger front air bag is
deployed.
RPASSENGER AIR BAG OFF lights up: the front-
passenger front air bag is deactivated. It will
then not be deployed in the event of an acci-
dent.
Depending on the person in the front-passenger
seat, the front-passenger front air bag must
either be deactivated or enabled; see the fol-
lowing points. You must make sure of this both
before and during a journey.
RChildren in a child restraint system:
whether the front-passenger front air bag is
enabled or deactivated depends on the instal-
led child restraint system, and the age and
size of the child. Therefore, be sure to observe
the notes on the "Occupant Classification
System (OCS)" (
Ypage 53) and on "Chil-
dren in the vehicle" (Ypage 61). There you
will also find instructions on rearward and
forward-facing child restraint systems on the
front-passenger seat.
RAll other persons: depending on the classi-
fication of the person in the front-passenger
seat, the front-passenger front air bag is ena-
bled or deactivated (
Ypage 53). Be sure to
observe the notes on "Seat
belts“ (
Ypage 46) and "Air bags"
(Ypage 50). There you can also find infor-
mation on the correct seat position.
Seat belts
Introduction
Seat belts are the most effective means of
restricting the movement of vehicle occupants
in the event of an accident or the vehicle rolling over. This reduces the risk of vehicle occupants
coming into contact with parts of the vehicle
interior or being ejected from the vehicle. Fur-
thermore, the seat belt helps to keep the vehicle
occupant in the best position in relation to the
air bag.
The seat belt system comprises:
RSeat belts
REmergency Tensioning Devices for the front
seat belts and the outer seat belts in the rear
RSeat belt force limiters for the front seat belts
and the outer seat belts in the rear
RBelt bags for the outer seat belts in the rear,
depending on the vehicle's equipment
If the seat belt is pulled out of the belt outlet
quickly or with a jerky movement, the belt
retractor locks. The belt strap cannot be extrac-
ted any further.
The Emergency Tensioning Device tightens the
seat belt in an accident, pulling the belt close
against the body. However it does not pull the
vehicle occupant back in the direction of the
backrest.
The Emergency Tensioning Device does not cor- rect an incorrect seat position or the routing of
an incorrectly fastened seat belt.
When triggered, a seat belt force limiter helps to
reduce the force exerted by the seat belt on the
vehicle occupant.
The seat belt force limiters for the front seats are
synchronized with the front air bags, which
absorb part of the deceleration force. This can
reduce the force exerted on the vehicle occu-
pants 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 otherwise
lead to the triggering of the Emergency Ten-
sioning Device in the event of an accident,
which will then need to be replaced.
