2015 MERCEDES-BENZ SPRINTER trailer

PARKTRONIC can suffer interference from:
R ultrasonic sources such as a truck's
compressed-air brakes, an automatic car
wash or a pneumatic drill
R attachments to the vehicle, e.g. rear
mounted racks
R number plates (vehicle license plates)
that are not affixed flat against the
bumper
R dirty or icy sensors
Remove a detachable trailer coupling if it is no longer required. PARKTRONIC measures the
minimum detection range to an obstacle from the bumper, not the ball coupling.
Range of the sensors PARKTRONIC does not account for obstacles
that are:
R beneath its detection range, e.g. persons,
animals or objects
R above its detection range, e.g. overhanging
loads, overhangs or truck loading ramps The sensors must be free of dirt, ice or slush.
Otherwise, they cannot function correctly.
Clean the sensors regularly, taking care not to
scratch or damage them (Y page 268). Front sensors

Notes on trailer towing
Important safety notes G
WARNING
Installing an unsuitable ball coupling may
result in overloading of the trailer tow hitch
and the rear axle. This applies especially if the ball coupling in question is longer or angled
differently. This could seriously impair the
driving characteristics and the trailer can
come loose. There is a risk of an accident.
You should only ever install a ball coupling
that has the permissible dimensions and that
is designed to meet your trailer-towing
requirements. Do not modify the ball coupling
or the trailer tow hitch. G
WARNING
If you use a ball coupling that is not approved for your vehicle, it may cause excessive strain on the trailer tow hitch. This can cause dam-
age to the vehicle and the trailer may come
loose during the journey. The handling may be
impaired and the rear axle may be overloaded.
This may lead to an accident involving serious
or even fatal injury.
Therefore note the following:
R Only install a ball coupling that is approved
for your vehicle.
R Before the journey, make sure that the ball
coupling is correctly installed and secured.
To do this, observe the operating instruc-
tions of the ball coupling manufacturer.
R Do not make any modifications to the ball
coupling or the trailer tow hitch.
You must observe the operating instructions
of the trailer tow hitch or ball coupling manu-
facturer. G
WARNING
If the ball coupling is not correctly installed
and secured, it could come loose while driving and endanger other road users. There is a risk
of an accident and injury.
Install and secure the ball coupling as descri-
bed in the ball coupling manufacturer's instal- lation instructions. Make sure that the ball
coupling is correctly installed and secured
before every journey. G
WARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The vehi- cle/trailer combination could even rollover.
There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary.
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 Towing a trailer
173Driving and parking Z

sure nobody is standing between the vehicle
and the trailer.
A trailer which is incorrectly coupled to the
towing vehicle could break away. A correctly
coupled trailer must be positioned horizon-
tally 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 316).
Where the values differ, the lowest is valid.
You will find values approved by the manu-
facturer on the identification plates and those
for the towing vehicle in the "Permissible
trailer loads and trailer drawbar noseweights"
section (Y page 177).
Your vehicle behaves differently with a trailer than without one.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradi-
ent-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 condi-
tions. Drive carefully. Maintain a safe dis-
tance. If you require any further explanation of the
information contained in the Operator's Man-
ual, please contact 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 vehi-
cle 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 a ball coupling that is
approved for your vehicle and Sprinter
trailer tow hitch. More information on the
availability, mounting and installation of the
trailer electrics is available at any qualified specialist workshop.
R The turn signals on the trailer are only guar-
anteed to function when incandescent
bulbs are used. You can obtain more infor-
mation 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 suita-
ble for installing detachable trailer cou-
plings.
R Do not attach rented trailer tow hitches or
other detachable trailer tow hitches to the
bumper.
R Minimize the risk of damage to the ball cou-
pling. If you do not require the ball coupling,
remove it from the ball coupling recess.
Weight information can be found in the “Per-
missible trailer and drawbar noseweights”
section (Y page 177).
i The height of the ball neck changes
according to the load on the vehicle. If this 174

is case, use a trailer with a height-adjusta-
ble trailer drawbar.
Driving tips The maximum permissible 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 vehi-
cle/trailer combinations in the relevant coun-
try, state or Canadian province.
When towing a trailer, your vehicle's handling
characteristics will be different in comparison 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 cruise control is acti-
vated.
This enables you to utilize the engine's brak-
ing effect and you do not need to brake so
heavily to keep the correct speed, which pro-
tects 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 author-
ized 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 capa-
bilities 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. 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 equip- ped 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

Observe the maximum permissible trailer
dimensions (width and length).
Most federal states and all Canadian provin-
ces 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 cou-
pling, 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 vehi- cle, the safety switch applies the trailer's
brakes. Towing a trailer
There are numerous legal requirements con-
cerning 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 any-
where you are driving to. Information is avail-
able 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 charac-
teristics.
R Before driving, check:
- that the trailer tow hitch and ball cou-
pling 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 section of the
trailer.
R If the trailer has electronically controlled
brakes, pull the vehicle/trailer combina-
tion 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 242).
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 driv-
ing 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 176
Towing a trailerDriving and pa
rking

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 dra-
matically while the air-conditioning system
is switched on, switch off the air-condition-
ing system.
Coolant heat can also be dissipated by
switching the airflow and the temperature
of the heater/air conditioning to the maxi-
mum 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 dis-
tance before you can return to your original
lane. Uncoupling a trailer
G
WARNING
If you uncouple a trailer with the overrun
brake engaged, you could trap your hand
between the vehicle and the trailer drawbar.
There is a risk of injury.
Do not uncouple a trailer if the overrun brake is engaged.
! Do not disconnect a trailer with an
engaged overrun brake. Otherwise, your
vehicle could be damaged by the rebound- ing of the overrun brake.
X Make sure the selector lever of the auto-
matic transmission is in position P.
X Apply the parking brake of the vehicle.
X Close all doors. X
Apply the parking brake of the trailer.
X In addition, secure the trailer against rolling
away with a wheel chock or similar object.
X Remove the trailer cable and safety chains
and decouple the trailer. Permissible trailer loads and trailer
drawbar noseweights
Weight information !
On vehicles with a permissible gross vehi-
cle weight of 11030 lbs (5003 kg), the per- missible gross combination weight is less
than the total of the permissible gross vehi-
cle weight and the permissible trailer load.
Exceeding the permissible gross combina-
tion weight can lead to damage to the driv-
etrain, 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 perm issible trailer drawbar
noseweight on the ball coupling is 500 lbs
(227 kg) or 750 lbs (340 kg). Theactual nose-
weight 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. Towing a trailer
