Vehicle equipment
i This manual describes all the standard

Occupant safety
Overview of occupant safety
In this section you will learn the most
important facts about the restraint system
components of the vehicle.
The restraint systems are:
R
Seat belts
R
Child restraint systems
R
LATCH-type (ISOFIX) child seat anchors
Additional protection is provided by:
R
SRS (Supplemental Restraint System)
R
NECK-PRO head restraints
R
PRE-SAFE
®
R
Air bag system components with:
-
PASSENGER air bag OFF indicator lamp
-
USA only: front passenger seat with
Occupant Classification System (OCS)
-
Canada only: front passenger seat with
BabySmart™ air bag deactivation system
The different air bag systems work
independently of each other. The protective
functions of the systems work in conjunction
with each other. Not all air bags are deployed
in an accident.
G
Warning
Modifications to or work improperly
conducted on restraint system components
or their wiring, as well as tampering with
interconnected electronic systems, can lead
to the restraint systems no longer functioning
as intended.
Air bags or Emergency Tensioning Devices
(ETDs), for example, could deploy
inadvertently or fail to deploy in accidents
although the deceleration threshold for air
bag deployment is exceeded. Therefore,
never modify the restraint systems. Do not
tamper with electronic components or their
software.
i See "Children in the vehicle"
(

page 60) for more information on
infants and children traveling with you in
the vehicle and restraints for infants and
children.
SRS (Supplemental Restraint System)
Introduction
SRS reduces the risk of occupants coming
into contact with the vehicle's interior in the
event of an accident. It can also reduce the
effect of the forces to which occupants are
subjected during an accident.
SRS consists of:
R
the
6
SRS warning lamp
R
air bags
R
air bag control unit (with crash sensors)
R
belt tensioners
R
belt force limiters
SRS warning lamps
SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The
6
SRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than a few seconds
after the engine is started.
The SRS components are in operational
readiness when the
6
SRS warning lamp
goes out while the engine is running.
