GWARNING
The function of systems or components can
be affected by conversions or modifications
to the vehicle. They might not function prop-
erly anymore and/or jeopardize the opera-
tional safety of the vehicle. There is an
increased risk of an accident and injury.
Conversions or modifications should always
be carried out at qualified specialist work-
shop.
If you intend to make modifications to your vehi-
cle, we strongly recommend that you contact
the distributor named on the inside of the front
cover. There you will receive all the necessary
information and a charge may be levied.
You alone accept the responsibility if body man-
ufacturers or dealers make modifications that
affect the final certification of the engine, the
vehicle or the equipment. This also applies to
the identification and documentation of modifi-
cations to the affected vehicle components.
You are responsible for certification and confir-
mation that:
Rall the applicable standards and regulations
that are affected by the vehicle modification
are met
Rthe modified vehicle fulfills the vehicle safety standards and emissions laws and regula-
tions
Rthe modifications or installation of accesso-
ries does not affect the safety of the vehicle

Introduction29
Z

The operating safety of the vehicle could be
jeopardized if you use parts, tires and wheels as
well as accessories relevant to safety which
have not been approved by Mercedes-Benz. This
could lead to malfunctions in safety-relevant
systems, e.g. the brake system. Only use genu-
ine Mercedes-Benz parts or parts of equal qual-ity. Only use tires, wheels and accessories that
have been specifically approved for your vehi-
cle.
We test genuine Sprinter parts, as well as con-
version parts and accessories that have been
specifically approved for the type of vehicle, for:
RReliability
RSafety
RSuitability
Despite ongoing market research, Mercedes-
Benz is unable to assess other parts. Therefore,
we accept no responsibility for the use of such
parts in Sprinter vehicles, even if they have been
officially approved or independently approved
by a testing center.
In some countries, certain parts are only offi-
cially approved for installation or modification if
they comply with legal requirements. All genu-
ine Sprinter parts satisfy these requirements.
Make sure that all parts are suitable for your
vehicle.
Always specify the vehicle identification number
(VIN) and engine number when ordering genuine Sprinter parts (
Ypage 276).
QR code for rescue card
The QR Code stickers are affixed to the B-pillar
on the driver's and front-passenger side.
In the event of an accident the rescue services
use the QR Code to quickly find the rescue card
for your vehicle. The current rescue card con-
tains the most important information on your
vehicle, e.g. the electric cable routes, in a com-
pact form.
Further information can be found at http://
www.mercedes-benz.de/qr-code.
Data stored in the vehicle
Information from electronic control
units
There are electronic control units installed in
your vehicle. Some of these are necessary for
your vehicle to operate safely, while some offer
support during driving (driver assistance sys-
tems). In addition, your vehicle offers comfort
and entertainment functions that are also made
possible by electronic control units.
Electronic control units contain data storage
systems that can temporarily or permanently
save technical information concerning the vehi-
cle's condition, component stress and mainte-
nance requirements as well as technical events
and malfunctions.
This information generally documents the con-
dition of a component, a module, a system or the
surroundings, for example:
ROperating conditions of system components
(e.g. levels, battery status, tire pressure)
RStatus messages concerning the vehicle or its
individual components (e.g. wheel revolution
number / speed, deceleration in movement,
lateral acceleration, display showing fastened
belts)
RMalfunctions and defects in key system com-
ponents (e.g. lights, brakes)
RInformation about events leading to vehicle
damage
RSystem responses in special driving situa-
tions (e.g. air bag deployment, intervention of
stability control systems)
RAmbient conditions (e.g. temperature, rain
sensor)
In addition to performing the actual control unit function, these data are used by manufacturers
to detect and rectify malfunctions and to opti-
mize vehicle functions. Most of these data are
volatile and processed only in the vehicle itself.
Only a small part of the data is stored in event or
malfunction memories.
When you use services, the technical data from
the vehicle can be read out by service network
employees or third parties. Service activities
include repairs, maintenance, warranty claims
and quality assurance measures. The data are
read out via the connection for OBD (on-board
diagnostics) in the vehicle, which is required by
law. The relevant offices in the service network
or third parties collect, process and use the

RAlways lean against the backrest while driv-
ing. Do not lean forward or lean against the
door or side window. You may otherwise be in
the deployment area of the air bags.
RAlways keep your feet in the footwell in front
of the seat. Do not put your feet on the dash-
board, for example. Your feet may otherwise
be in the deployment area of the air bag.
RFor this reason, always secure persons less
than 5 ft (1.50m)tall in suitable restraint sys-
tems. Up to this height, the seat belt cannot
be worn correctly.
If a child is traveling in your vehicle, also
observe the following notes:
RAlways secure children under twelve years of age and less than 5 ft (1.50 m)tall in suitable
child restraint systems.
RChild restraint systems should be installed on
the rear seats.
RAlways secure a child in a rearward-facing
child restraint system on a suitable rear seat.
The front-passenger front air bag cannot be
deactivated.
RAlways observe the instructions and safety
notes on "Children in the vehicle"
(
Ypage 49) and on the "Child restraint sys-
tem on the front-passenger seat"
(
Ypage 52) in addition to the child restraint
system manufacturer's installation and oper-
ating instructions.
Objects in the vehicle interior may prevent
an air bag from functioning correctly. Before
starting your journey and to avoid risks resulting from the speed of the air bag as it deploys, make
sure that:
Rthere are no people, animals or objects
between the vehicle occupants and an air bag
Rthere are no objects between the seat, door
and B-pillar
Rthere are no hard objects, e.g. coat hangers,
hanging on the grab handles or coat hooks
Rno accessories, such as cup holders, are
attached to the vehicle within the deployment
area of an air bag, e.g. to doors or side win-
dows
Rno heavy, sharp-edged or fragile objects are in
the pockets of your clothing. Store such
objects in a suitable place
GWARNING
If you modify the air bag cover or affix objects
such as stickers to it, the air bag can no longer
function correctly. There is an increased risk
of injury.
Never modify an air bag cover or affix objects
to it.
GWARNING
Sensors to control the air bags are located in
the doors. Modifications or work not per-
formed correctly to the doors or door panel-
ing, as well as damaged doors, can lead to the
function of the sensors being impaired. The air
bags might therefore not function properly
anymore. Consequently, the air bags cannot
protect vehicle occupants as they are
designed to do. There is an increased risk of
injury.
Never modify the doors or parts of the doors.
Always have work on the doors or door pan-
eling carried out at a qualified specialist work-
shop.
Front air bags
Driver's air bag :deploys in front of the steer-
ing wheel. Front-passenger front air bag ;
deploys in front of and above the glove box and
the center console.
When deployed, the front air bags offer addi-
tional head and thorax protection for the occu-
pants in the front seats.
Side impact air bags
Depending on the vehicle's equipment, some
front seats are equipped with a side impact air
bag; see the AIRBAG label on the outer side of
the seat backrest.

Highbeam Assist
General notes
You can use this function to set the headlamps
to change between low beam and high beam
automatically. The system recognizes vehicles
with their lights on, either approaching from the
opposite direction or traveling in front of your
vehicle, and consequently switches the head-
lamps from high beam to low beam.
Once the system no longer detects any other
vehicles, it reactivates the high-beam head-
lamps.
The system's optical sensor is located behind
the windshield near the overhead control panel.
Important safety notes
GWARNING
Highbeam Assist does not recognize road
users:
Rwho have no lights, e.g. pedestrians
Rwho have poor lighting, e.g. cyclists
Rwhose lighting is blocked, e.g. by a barrier
In very rare cases, Highbeam Assist may fail to
recognize other road users who have lights, or
may recognize them too late. In this or similar situations, the automatic high-beam head-
lamps will not be deactivated or will be acti-
vated regardless. There is a risk of an acci-
dent.
Always carefully observe the traffic conditions
and switch off the high-beam headlamps in
good time.
Highbeam Assist cannot take into account road,
weather or traffic conditions. Highbeam Assist
is only an aid. You are responsible for adjusting
the vehicle's lighting to the prevailing light, vis-
ibility and traffic conditions.
In particular, the detection of obstacles can be
restricted if there is:
Rpoor visibility, e.g. due to fog, heavy rain or
snow
Rdirt on the sensors or anything else covering
the sensors
Activating/deactivating Highbeam
Assist
XTo activate: switch on the Highbeam Assist
function using the on-board computer
(
Ypage 170).
XTurn the light switch to the Ãposition.
XPress the combination switch beyond the

Highbeam Assist is active.
The _ or
indicator lamp in the
multifunction display lights up when it is dark
and the light sensor activates the low-beam
headlamps.
If you are driving at speeds above approx-
imately 22 mph (35 km/h) and no other road
users have been detected:
The high-beam headlamps are switched on
automatically. The Kindicator lamp in the
instrument cluster also lights up.
If you are driving at speeds below approx-
imately 19 mph (30 km/h), other road users
have been detected or the roads are ade-
quately lit:
The high-beam headlamps are switched off
automatically. The Kindicator lamp in the
instrument cluster goes out. The _or
indicator lamp in the multifunction
display remains lit.
XTo deactivate: move the combination switch
back to its normal position or move the light
switch to another position.
The _ or
indicator lamp in the
multifunction display goes out.
