The SRS performs a self-test at regular
intervals when the ignition is switched
on and while the engine is running. Mal-
functions can therefore be detected in
good time.
The

warning lamp in the instru-
ment cluster (

approximately 4 seconds when you
switch on the ignition.

Activation of emergency tensioning
retractors, belt force limiters and air-
bagsIn the event of a collision, the
sensor in
the airbag control unit evaluates impor-
tant physical data, such as duration, di-
rection and rate of vehicle deceleration
or acceleration. Based on the evaluation
of this data and depending on the vehi-
cle’s rate of longitudinal deceleration in
a collision, in the first stage, the airbag
control unit pre-emptively triggers the
emergency tensioning retractors.

In this case, have the SRS system
checked and repaired immediately at a
qualified specialist workshop which has
the necessary specialist knowledge and
tools to carry out the work required.The manufacturer recommends that you
use an authorized Sprinter Dealer for this
purpose. In particular, work relevant to
safety or on safety-related systems must
be carried out at a qualified specialist
workshop.

Vehicle deceleration or acceleration and
the direction of the force are essentially
determined by:\4
the distribution of the force during
the impact
\4
the collision angle
\4
the deformation characteristics of
the vehicle
\4
the composition of the object in-
volved in the collision, for example
the other vehicle
Factors that cannot be seen or mea-
sured until after the collision are not
used to determine whether the airbag
should be triggered and are not decisive
for this.The vehicle may be substantially deformed
without an airbag being triggered, for ex-
ample if only relatively easily-deformable
vehicle parts such as the hood or fenders
are affected by the collision and the re-
quired deceleration threshold is not
reached. On the other hand, airbags may
be triggered even though the vehicle only
displays minor deformation, if, for exam-
ple, rigid vehicle parts such as a longitudi-
nal member are affected by the impact,
thus causing vehicle deceleration to ex-
ceed the pre-determined threshold.
Emergency tensioning retractors,
belt force limitersIf the vehicle is equipped with a driver’s
airbag, the driver’s and the passenger’s
seat belts are equipped with emergency
tensioning retractors.
A belt force limiter additionally installed
in the seat belt reduces the load exerted
by the seat belt on the occupant when it
is triggered.
Emergency tensioning retractors ten-
sion the seat belts in an accident, pulling
them close against the body.

the initial stages of a collision
\4
in the event of a side impact, if the
vehicle suddenly decelerates or ac-
celerates in a lateral direction at the
initial stage of the impact and the ve-
hicle is equipped with thorax /
sidebags and / or windowbags.If the emergency tensioning retractors
are triggered, you will hear a bang that is
generally harmless to your hearing. A
small amount of powder may also be re-
leased. The

The manufacturer recommends that you
use an authorized Sprinter Dealer for this
purpose. In particular, work relevant to
safety or on safety-related systems must
be carried out at a qualified specialist
workshop.Observe the safety regulations when dis-
posing of emergency tensioning retrac-
tors. You can see a copy of these
regulations at any authorized Sprinter
Dealer.
Airbag systemWarning
G
\4To reduce the risk of serious or fatal
injuries in the event of an accident
with a high rate of deceleration, for
example due to an airbag inflating
within milliseconds, or due to sudden
braking, please observe the following
points:
Continued
Warning (Continued)
G
All vehicle occupants must select a seat
position in which they can wear their seat
belt correctly and which is as far back
from the airbag as possible. The seat po-
sition of the driver must be such that the
vehicle can be driven safely. The distance
from the driver’s seat to the pedals must
be such that the driver can fully depress
the pedals. The distance between the
driver’s chest and the center of the airbag
cover must be more than 25 cm. The driv-
er’s arms should be slightly bent when
holding the steering wheel.

\4Vehicle occupants should wear their
seat belt correctly at all times and
lean back against the backrest, which
should be positioned as upright as
possible. The head restraints should
support the back of the head at about
eye level.\4Move the passenger’s seat as far to
the rear as possible, especially if a
child is secured in a restraint system
installed on this seat.
Continued
Warning (Continued)
G
\4On vehicles with a passenger’s air-
bag, it is not permitted to secure a
rearward-facing child restraint sys-
tem to the passenger’s seat
(\2page 56). Children in a rearward-
facing child restraint system must be
secured on a suitable rear seat.\4Do not lean forward, for example over
the padded boss of the steering
wheel, especially when the vehicle is
in motion.
Continued
Warning (Continued)
G
\4Only hold the steering wheel by the
outer rim. This allows the airbag to in-
flate fully. If you hold the inside of the
steering wheel, you could be injured if
the airbag were to be triggered.\4Do not put your feet on the dash-
board.\4Do not lean on the doors from inside
the vehicle.\4Make sure that no persons, animals
or objects are present between the
vehicle occupants and the deploy-
ment range of the airbags.

Thorax sidebags*Warning
G
For safety reasons, the manufacturer rec-
ommends that you use seat covers that
have been tested for Sprinter vehicles
and that have a seam for thorax /
sidebags. A thorax / sidebag may other-
wise not inflate correctly and could fail to
provide the intended degree of protection
in the event of a collision. You can obtain
these covers from an authorized Sprinter
Dealer, for example.
Warning
G
To reduce the risk of injury to occupants
if a thorax / sidebag is triggered, make
sure that:
\4no persons, animals or objects are
present between the vehicle occu-
pants and the thorax / sidebag de-
ployment range
\4no accessories, for example cup hold-
ers, are secured to the doors
\4only light items of clothing are hung
from the coat hooks in the vehicle
\4there are no heavy or sharp objects in
the pockets of items of clothing
Warning
G
Observe the following to reduce the risk of
serious or fatal injury if the thorax /
sidebag is triggered:
\4Vehicle occupants – in particular, chil-
dren – must never lean their head
against the area of the window in
which the thorax / sidebag inflates.
\4Vehicle occupants must wear their
seat belt correctly at all times and
lean back against the backrest, which
should be positioned as upright as
possible.
\4Always secure children who are less
than 5 ft (1.50 m) tall or under
12 years of age in a suitable child re-
straint system.
