WARNING
Modifications to the restraint systems could
result in them not functioning properly any
more. The restraint systems could then no
longer protect vehicle occupants as they are
designed to do and could fail in the even tof
an accident or activate unexpectedly, for
example. There is an increased risk of injury.
Never modify parts of the restraint systems.
Do no tattemp tto modify the wiring as well as
electronic components or their software.
If it is necessary to modify an air bag system
to accommodate a person with disabilities,
contact an authorized Mercedes-Benz center.
USA only: for further information contact our
Customer Assistance Center at
1-800-FOR-MERCedes (1800-367-6372).
In this section you will learn the most
important facts about the restraint system
components of the vehicle.
The restraint system consists of:
R Seat belts
R Child restraint systems
R LATCH-type (ISOFIX) child seat securing
system
SRS (Supplemental Restraint System) and
the air bag system offer additional protection
potential. Although the systems are independent, their
protective functions work in conjunction with
one another.
i
For information on infants and children
traveling with you in the vehicle as well as
restraint systems for infants and children,
see the "Children in the vehicle" section
(Y page 50). SRS (Supplemental Restraint System)
Introduction SRS consists of:
R
0008 warning lamp
R Air bags
R Air bag control unit with crash sensors
R ETDs for the driver's and co-driver's seat
R Seat belt force limiters
R Seat belt force limiters for the driver's and
co-driver seats
SRS reduces the risk of occupants hitting
parts of the vehicle interior in the event of an
accident .Inaddition, it can reduce the forces
the occupants are subjected to during an
accident.
SRS warning lamp G
WARNING
If SRS is malfunctioning, child restraint
system components may be triggered
unintentionally or might not be triggered at all
in the event of an acciden twith a high rate of
vehicle deceleration. There is an increased
risk of injury, possibly even fatal.
Have SRS checked and repaired immediately
at a qualified specialist workshop.
SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. This allows malfunctions to
be detected in good time. 42
Occupant safetySafety

When you switch on the ignition, the
0008
warning lamp in the instrument cluster lights
up for approximately 4seconds.
A malfunction has occurred if the 0008
warning lamp:
R does not light up when you switch on the
ignition, or
R does not go out within a few seconds of
switching on the ignition, or
R lights up again
Safet yguidelines for seat belts,
Emergency Tensioning Devices (ETDs)
and air bags G
WARNING
R Damaged sea tbelts or seat belts that have
been subjected to stress in an accident
must be replaced and their anchoring
points must also be checked. Only use seat
belts which have been installed or supplied
by a qualified specialist workshop.
R Air bags and pyrotechnic Emergency
Tensioning Devices (ETDs) contain
perchlorate material, which may require
special handling and regard for the
environment. Check with your local
government's disposal guidelines.
California residents, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm.
R Air bags and ETDs are designed to function
on a one-time-only basis. An air bag or ETD
that has deployed must be replaced.
R Do not pass seat belts over sharp edges.
They could tear.
R Do not make any modification that could
change the effectiveness of the seat belts.
R Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
R No modifications of any kind may be made
to any components or wiring of the SRS.
R Do not change or remove any component
or part of the SRS. R
Do not install additional paneling, seat
covers, badges etc.o ver the steering wheel
hub, co-driver's front air bag cover,
outboard sides of the seat backrests, door
trim panels, or door frame trims.
R Do not install additional electrical/
electronic equipment on or near SRS
components and wiring.
R Keep the area between air bags and
occupants free of objects (e.g. packages,
purses, umbrellas etc.).
R Do not hang items such as coat hangers
from the coat hooks or handles over the
door. These items may be thrown around in
the vehicle and cause head and other
injuries when the window curtai nair bag is
deployed.
R Air bag system components will be hot after
an air bag has inflated. Do not touch them.
R Never place your feet on the instrument
panel or on the seat. Always keep both feet
on the floor in front of the seat.
R Improper repair work creates a risk of
rendering the SRS inoperative or causing
unintended air bag deployment. Work on
the SRS must therefore only be performed
by qualified technicians. Please contac ta
qualified specialist workshop.
R For your protection and the protection of
others, when scrapping the air bag unit or
ETD, our safety instructions must be
followed. These instructions are available
from any authorized Sprinter Dealer.
R Given the considerable deployment speed,
required inflation volume, and the material
of the air bags, there is the possibility of
abrasions or other, potentially more serious
injuries resulting from air bag deployment.
If you sell your vehicle, we strongly
recommend that you infor mthe subsequent
owner that the vehicle is equipped with SRS.
