towing MERCEDES-BENZ SPRINTER 2017 MY17 Operator’s Manual

Loading a trailer
!Utilize the maximum permissible nose-
weight as fully as possible. Do not allow the
weight to fall below the minimum permissible
noseweight, otherwise the trailer may come
loose.
RThe load must be distributed over the vehicle
and the trailer so as not to exceed either the
maximum permissible values for the gross
vehicle weight rating (GVWR) and gross trailer weight (GTW), the gross combination weight
rating (GCWR), nor the maximum permissible
gross axle weight rating (GAWR) and trailer
drawbar noseweight rating of your vehicle.
RAdd the drawbar noseweight on the ball cou-
pling (TWR) to the rear axle load. This will pre-
vent you from exceeding the permissible
gross axle weight (GAWR).
RAdd the drawbar noseweight on the ball cou-
pling (TWR) to the vehicle payload. This will
ensure that you do not exceed the permissi-
ble gross vehicle weight rating (GVWR).
Checking the vehicle and trailer weight
RMake sure the weights of the towing vehicle
and the trailer comply with the maximum per-missible values. Have the vehicle/trailer com-
bination weighed on a calibrated weigh-
bridge. The vehicle/trailer combination con-
sists of the towing vehicle including the driver,
passengers and load, as well as the loaded
trailer.
RCheck the maximum permissible gross axle
weight rating of the front and rear axles
(GAWR), the gross trailer weight (GTW), the
gross combination weight rating (GCWR) and
the noseweight of the trailer drawbar (TWR).
Trailer power supply
!
Incorrect wiring of the connector plug could,
under certain circumstances, cause malfunc-
tions in the vehicle's other electronic sys-
tems. We therefore recommend having the
connector plug wired at a qualified specialist
workshop.
!You can connect accessories with a maxi-
mum 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 elec-
trical installations for trailer towing. Depending
on your trailer, you may need an adapter to con-
nect 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.
Further information on the electrical equipment
currently installed on your vehicle and on instal-
ling trailer electrics can be obtained at any quali-
fied specialist workshop.

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 possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 27).
Stowage spaces and stowage com-
partments
Important safety notes
GWARNING
If objects in the passenger compartment are
stowed incorrectly, they can slide or be
thrown around and hit vehicle occupants. In
addition, cupholders, open stowage spaces
and mobile phone brackets cannot always
retain all objects they contain. There is a risk of injury, particularly in the event of sudden
braking or a sudden change in direction.
RAlways stow objects so that they cannot be
thrown around in such situations.
RAlways make sure that objects do not pro-
trude from stowage spaces, parcel nets or
stowage nets.
RClose the lockable stowage spaces before
starting a journey.
RAlways stow and secure heavy, hard, poin-
ted, sharp-edged, fragile or bulky objects in
the trunk.
In addition, observe the information in the
"Loading guidelines" section (
Ypage 208).

Important safety notes
GWARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
You must observe the legal requirements for the
country in which you are currently driving when
operating mobile phones.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is cov-
ering a distance of 44 feet (approximately 14 m)
every second.
You and others can suffer health-related dam-
age through electromagnetic radiation. By using
an exterior antenna, a possible health risk
caused by electromagnetic fields, as discussed
in scientific circles, is taken into account. Only
have the exterior antenna installed by a qualified
specialist workshop.
We recommend the use of an approved exterior
antenna for operating the mobile phone. Only in
this way can optimal mobile phone reception
quality in the vehicle be ensured and mutual
interference between the vehicle electronics
and mobile phones minimized.
Observe the legal requirements for each indi-
vidual country.
Mobile phone pre-installation
The mobile phone pre-installation includes a
hands-free system integrated into the vehicle.
The microphone for the hands-free system is
installed in the overhead control panel or in the
overhead stowage compartment together with
the front interior light.
In order to use the hands-free system, you will
need a special bracket. The Sprinter accesso-
ries include brackets for various mobile phone
models.
iMobile phone brackets which are available
from various manufacturers on the open mar- ket are not compatible with the Sprinter tele-
phone system. You can recognize suitable
holders for your mobile phone by the imprin-
ted star and the B6 spare part number on the back of the bracket.
Detailed instructions for use can be found in the
operating instructions for the mobile phone

tions for the mobile phone pre-installation.

country in which you are currently driving when
operating mobile communication equipment.
Please remember, a navigation system does not
supply information on the load-bearing capacity of bridges or the overhead clearance of under-
passes. The driver remains responsible for
safety at all times.
