2013 MERCEDES-BENZ SPRINTER tow bar

!
Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
Always observe the operating instructions
provided by the manufacturers of the trailer
coupling and the ball coupling.
Couple and decouple the trailer carefully.
When backing up the towing vehicle, make
sure nobody is standing between the vehicle
and the trailer.
At railer which is incorrectly coupled to the
towing vehicle could brea kaway. Acorrectly
coupled trailer must be positioned
horizontally behind the towing vehicle.
Ensure that the following weights are not
exceeded:
R the permissible noseweight
R the permissible trailer load
R the permissible rear axle load of the towing
vehicle
R the permissible gross weight of both the
towing vehicle and the trailer
R the permissible gross combination weight
The applicable permissible values that may
not be exceeded can be found:
R in your vehicle documents
R on the type plates for the trailer tow hitch
R on the type plates for the trailer
R on the vehicle identification plate
(Y page 315).
Where the values differ, the lowest is valid.
You will find values approved by the
manufacturer on the identification plates and
those for the towing vehicle in the
"Permissible trailer loads and trailer drawbar
noseweights" section (Y page 169).
Your vehicle behaves differently with a trailer
than without one.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and
gradient-climbing capability
R has an increased braking distance R
is more susceptible to strong crosswinds
R requires more sensitive steering
R has a larger turning circle
This may impair the handling characteristics.
When towing a trailer, always adjust your
speed to suit the road and weather
conditions. Drive carefully. Maintain a safe
distance.
If you require explanations for the information
in this Operator's Manual, contract an
authorized Sprinter Dealer.
General notes R
Observe the legally prescribed maximum
speed for vehicle/trailer combinations in
the relevant country, state or Canadian
province. Before setting off, check the
vehicle documents of the your trailer to find
out the permissible maximum speed.
This reduces the risk of accidents.
R Install only an approved trailer coupling on
your vehicle. Only use aball coupling that
is approved for your vehicle and Sprinter
trailer tow hitch. More information on the
availability, mounting and installatio nofthe
trailer electrics is available at any qualified
specialist workshop.
R The turn signals on the trailer are only
guaranteed to function when incandescent
bulbs are used. You can obtain more
information about installing the trailer
electrics at any qualified specialist
workshop.
R The trailer coupling is one of the most
important vehicle parts with regard to road
safety. The notes on operation, care and
maintenance issued by the manufacturer
should be observed.
R The bumpers of your vehicle are not
suitable for installing detachable trailer
couplings. Towing

R
Do not install rented trailer couplings or
other detachable trailer couplings to the
bumpers.
R Minimize the risk of damage to the ball
coupling .Ifyou do not require the ball
coupling, remove it from the ball coupling
recess.
Weight information can be found in the
“Permissible trailer and drawbar
noseweights” section (Y page 169).
Note that, when towing atrailer,
PARKTRONIC is only available with limitations
or not at all (Y page 160).
i The height of the ball neck changes
according to the load on the vehicle. If this
is case, use a trailer with a height-
adjustable trailer drawbar.
Driving tips The maximu
mpermissible speed for vehicle/
trailer combination depends on the type of
trailer. Before setting off, check the vehicle
documents of the your trailer to find out the
permissible maximum speed. Observe the
legally prescribed maximum speed for
vehicle/trailer combinations in the relevant
country, state or Canadian province.
When towing a trailer, your vehicle's handling
characteristics will be differen tincomparison
to when driving without a trailer and it will
consume more fuel.
On long, steep downhill slopes you must
select shift range 3,2or 1in good time.
i This also applies if you have activated
cruise control.
This enables you to utilize the engine's
braking effect and you do not need to brake
so heavily to keep the correc tspeed. which
protects the brake system and prevents the
brakes from overheating and wearing too
quickly. If you need to brake additionally, to
not depress the brake pedal constantly, but
periodically. Driving tips If the trailer begins to swing from side to side:
X
Do not accelerate.
X Do not counter-steer.
X Brake if necessary.
i You can reduce the risk of the trailer
swinging and rocking by retrofitting anti-
roll bars or trailer stability programs .More
information is available from your
authorized Sprinter Dealer.
R Maintain a greater distance than you would
when driving without towing a trailer.
R Avoid sudden braking. Apply the brakes
gently at first to allow the trailer brake to
overrun. Then, increase the brake force
quickly.
R The figures for the gradient climbing
capabilities from a standstill refer to sea
level. When driving in mountainous areas,
note that the power output of the engine,
and with it its gradient climbing capability,
decrease with increasing altitude. Attaching and removing the ball
coupling

is installed and secured correctly before every
journey.
If your vehicle is equipped with a Sprinter
trailer tow hitch, you need a ball coupling that
is approved for the trailer tow hitch.
When mounting and removin gthe approved
ball coupling, observe the relevant
information in the operating instructions of
the ball coupling manufacturer.
If you cannot mount the ball coupling
correctly, remove it. In this case, the ball
coupling may not be used for towing a trailer.
Notes on the permissible dimensions and
weights can also be found on the
identification plate of the trailer tow hitch.
You can obtain advice from a qualified
specialist workshop. Coupling up a trailer
! Do not connect the trailer's brake system
(if featured) to the hydraulic brake system
of the towing vehicle, as the latter is
equipped with an anti-lock brake system.
Doing so will result in a loss of function of
the brake systems of both the vehicle and
the trailer. Trailer coupled ready for use

Most federal states and all Canadian
provinces require by law:
R safety chains between the towing vehicle
and the trailer. The chains should be cross-
wound under the trailer drawbar. They must
be fastened to the vehicle's trailer
coupling, not to the bumper or the axle.
Leave enough slack in the chains. This
allows you to drive round tight corners.
R a separate brake system for certain types
of trailer.
R a safety switch for braked trailers. Find out
the specific requirements according to the
applicable laws.
If the trailer detaches from the towing
vehicle, the safety switch applies the
trailer's brakes. Towing
atrailer
There are numerous legal requirements
concerning the towing of a trailer, e.g .speed
restrictions. Make sure your vehicle/trailer
combination complies with local laws. This
not only means where you live, but also
anywhere you are driving to. Information is Towing
atrailer
171Driving an d parking Z

available from the police and local
authorities.
Observe the following when towing a trailer:
R
Practice driving around bends, stopping
and backing up at a place where there is no
traffic. This enables you to gain experience
and get used to the new handling
characteristics.
R Before driving, check:
-that the trailer tow hitch and ball
coupling are secure
- that the safety switch for a braked trailer
is functioning properly
- that the safety chains are secure and not
damaged
- that the electrical connections are
secure
- that the lights are working
- that the wheels are in good order and the
tire pressure is correct
R Adjust the exterior mirrors to provide an
unobstructed view of the rear sectio nofthe
trailer.
R If the trailer has electronically controlled
brakes, pull the vehicle/trailer
combination away carefully. Brake
manually using the brake controller and
check that the brakes are working.
R Secure the load on the trailer according to
the applicable specifications and current
standards on securing loads
(Y page 234).
R When driving with a trailer, check at regular
intervals that the load is secured and that
the brakes and lights are working.
R Bear in mind that the handling will be less
stable when towing a trailer than when
driving without one. Avoid sudden steering
movements.
R The vehicle/trailer combination is heavier,
accelerates more slowly and has a
decreased gradient climbing capability and
a longer braking distance.
It is more susceptible to crosswinds and
requires cautious steering. R
If possible, do not brake suddenly, but
rather moderately at first so that the trailer
can activate its brakes. Then increase the
force on the brake pedal.
R If the automatic transmission repeatedly
shifts between gears when driving on
inclines, restrict the shift range. Select shift
range 4,3,2or 1.
Driving in a low gear and at a low speed
reduces the risk of damaging the engine.
R When driving on a downhill gradient, shift
to a low gear and take advantage of the
engine's braking effect.
Avoid continuous brake application as this
may overheat the vehicle brakes and, if
installed, the trailer brakes.
R If the coolant temperature increases
dramatically while the air-conditioning
system is switched on, switch off the air-
conditioning system.
Coolant heat can also be dissipated by
switching the airflow and the temperature
of the heater/air conditioning to the
maximum level. Open the windows if
necessary.
R When overtaking, pay particular attention
to the extended length of your vehicle/
trailer combination.
Due to the length of your vehicle/trailer
combination you need an additional
distance before you can return to your
original lane. Uncoupling

drawbar noseweights
Weight information !
On vehicles with a permissible gross
vehicle weight of 11030 lbs (5003 kg), the
permissible gross combination weight is
less than the total of the permissible gross
vehicle weight and the permissible trailer
load. Exceeding the permissible gross
combination weight can lea dto damage to
the drivetrain, to the transmission or to the
trailer tow hitch.
If the vehicle or the trailer is fully laden, the
relevant value for the permissible gross
vehicle weight or the permissible trailer
load is therefore lower. In this case, the
trailer or the vehicle may only be partially
loaded.
The gross trailer weight (GTW) is calculated
by adding the weight of the trailer to the
weight of the load and equipment.
The maximum gross vehicle weight is vehicle-
specific and equipment-dependent:
5,000 lbs (2,268 kg) or 7,500 lbs (3,402 kg).
The maximum permissible trailer drawbar
noseweight on the ball coupling is 500 lbs
(227 kg) or 750 lbs (340 kg). The actual
noseweight may not exceed the value given
on the identification plates of the trailer tow
hitch or the trailer. If the values vary, the
lowest value always applies. The gross combination weight rating (GCWR)
is calculated by adding the gross weight of the
trailer to the gross vehicle weight including a
driver's weight of approximately 150 lbs
(68 kg). The permissible Gross Combination
Weight Rating is vehicle-specific and depends
on the equipment level.
When driving with a trailer, you should not
exceed the permitted Gross Combination
Weight Rating (GCWR).
The permissible values, which must not be
exceeded, can be found in your vehicle
documents and on the trailer tow hitch type
plates for the trailer and the vehicle
(Y page 315). The basic values approved by
the manufacturer can also be found in the
"Technical data" section ( Ypage 328). If the
values vary, the lowest value always applies.
Loading atrailer !
Utilize the maximum permissible
noseweigh tas fully as possible.D o not
allow the weight to fall below the minimum
permissible noseweight, otherwise the
trailer may come loose.
R You must distribute the load on the vehicle
and trailer so that the permitted maximum
values for the gross vehicle weight (GVWR),
gross trailer weight (GTW) and gross
combined weight (GCWR) as well as
permitted gross axle loads (GAWR) and
noseweight (TWR) of your vehicle are not
exceeded.
R Add the drawbar noseweight on the ball
coupling (TWR) to the rear axle load. This
will prevent you from exceeding the
permissible gross axle weight (GAWR).
R Add the drawbar noseweight on the ball
coupling (TWR) to the vehicle payload. This
will prevent you from exceeding the
permissible gross vehicle weight (GVWR). Towing

Checking the vehicle and trailer weight
R
Make sure the weights of the towing vehicle
and the trailer comply with the maximum
permissible values .Have the vehicle/
trailer combinatio nweighed on a calibrated
weighbridge. The vehicle/trailer
combination consists of the towing vehicle
including the driver, passengers and load,
as well as the loaded trailer.
R Check 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
malfunctions in the vehicle's other
electronic systems. We therefore
recommend having the connector plug
wired at a qualified specialist workshop.
! You can connecta ccessories with a
maximum power consumption of 240 Wto
the permanent powe rsupply.
You must no tcharge 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 apermanen tpower 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
guaranteed to function when incandescent
bulbs are used. Further information on the electrical
equipment currently installed on your vehicle
and on installing trailer electrics can be
obtained at any qualified specialist workshop.174
