WARNING
Exhaust fumes, some of its constituents, and
certain vehicle components contain or emit
chemicals known to the State of California to
cause cancer and birth defects or other her-
itable genetic damage.
In addition, certain fluids contained in vehi-
cles, and certain products that are used as
components, contain chemicals known to the
State of California to cause cancer and birth
defects or other heritable genetic damage.
Air bags and pyrotechnic Emergency Tension-
ing Devices (ETDs) and remote control bat-
teries contain perchlorate material, which
may require special handling and regard for
the environment. Check with your local gov-
ernment's disposal guidelines.
In California, see www.dtsc.ca.gov/ Hazard-
ousWaste/Perchlorate/ index.cfm. G
WARNING
If you do not have the prescribed service/
maintenance work or any required repairs
carried out, this can result in malfunctions or
system failures. There is a risk of an accident.
Always have the prescribed service/mainte-
nance work as well as any required repairs
carried out at a qualified specialist workshop. G
WARNING
Modifications to electronic components, their
software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as
intended and/or jeopardize the operating
safety of the vehicle. There is an increased
risk of an accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop. G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system. There is a
risk of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
The general operating permit for your vehicle
could be rendered invalid If you carry out
modifications to electronic components,
their software as well as wiring.
Driving off-road or on construction sites
increases the possibility of vehicle damage
which may in turn lead to the failure of certain
assemblies and systems.
There is a risk of damage to the vehicle if:
R the vehicle makes contact with the ground,
e.g. on a high curb or a loose road surface
R you drive too quickly over an obstacle, e.g.
a curb or a pothole
R a heavy object hits the underbody or chas-
sis component
In these or similar situations, the vehicle
body, the underbody, chassis components,
wheels or tires could be damaged even if this 24

Useful information
This Operator's Manual describes all models
as well as standard and optional equipment
of your vehicle that were available at the time
of going to print. Country-specific variations
are possible. Note that your vehicle may not
be equipped with all of the described func-
tions. This also applies to systems and func-
tions relevant to safety.

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 event of
an accident or activate unexpectedly, for
example. There is an increased risk of injury.
Never modify parts of the restraint systems.
Do not attempt to 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 impor-
tant facts about the restraint system compo-
nents 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.

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
007E 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. In addition, it can reduce the forces
the occupants are subjected to during an
accident.
SRS warning lamp G
WARNING
If SRS is malfunctioning, child restraint sys-
tem components may be triggered uninten-
tionally or might not be triggered at all in the
event of an accident with 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
007E
warning lamp in the instrument cluster lights
up for approximately 4 seconds.
A malfunction has occurred if the 007Ewarn-
ing 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
Safety guidelines for seat belts, Emer-
gency Tensioning Devices (ETDs) and
air bags G
WARNING
R Damaged seat belts 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 Ten-
sioning Devices (ETDs) contain perchlorate
material, which may require special han-
dling and regard for the environment.
Check with your local government's dis-
posal 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 cov-
ers, badges etc. over the steering wheel
hub, co-driver's front air bag cover, out-
board sides of the seat backrests, door trim
panels, or door frame trims.
R Do not install additional electrical/elec-
tronic equipment on or near SRS compo-
nents and wiring.
R Keep the area between air bags and occu-
pants 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 inju-
ries when the window curtain air 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 ren-
dering the SRS inoperative or causing unin-
tended air bag deployment. Work on the
SRS must therefore only be performed by
qualified technicians. Please contact a
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 fol-
lowed. 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 recom-
mend that you inform the subsequent owner
that the vehicle is equipped with SRS. Also
refer them to the applicable section in the

! Incorrect wiring of the connector plug
could, under certain circumstances, cause
malfunctions in the vehicle's other elec-
tronic systems. We therefore recommend
having the connector plug wired at a quali-
fied specialist workshop.
! You can connect accessories with a max-
imum power consumption of 240 W to the
permanent power supply.
You must not charge a trailer battery using
the power supply.
Your vehicle may be equipped with various
electrical installations for trailer towing.
Depending on your trailer, you may need an
adapter to connect the electrical system of
the trailer with that of the vehicle.
The trailer socket of your vehicle is equipped
at the factory with a permanent power supply.
The permanent power supply is on the trailer
socket pin assignment 4.
Note that the permanent power supply of the
trailer is not switched off when the on-board
voltage is low. This can completely discharge
the starter battery of your vehicle.
The turn signals on the trailer are only guar-
anteed to function when incandescent bulbs
are used.
