cle's distance from the obstacle.
From the:
Rsixth segment, an intermittent warning tone
sounds for approximately 2 seconds.
Rseventh segment, a continuous warning tone
sounds. This indicates that you have now
reached the minimum distance.
Roll-back warning
PARKTRONIC automatically monitors the area
behind the vehicle if the vehicle begins to roll
backwards without reverse gear engaged, e.g.
after stopping on an uphill gradient.
If PARKTRONIC recognizes an obstacle at a dis-
tance of at most 31 in (80 cm), all the segments
in the warning displays light up. A continuous
warning tone also sounds as the vehicle
approaches the obstacle and for a further
2 seconds after the vehicle has come to a halt.
Activating/deactivating PARKTRONIC
XPress the fbutton.
If PARKTRONIC is deactivated, the indicator
lamp in the switch lights up.
Towing a trailer
PARKTRONIC detects a coupled trailer if your
vehicle is equipped with the corresponding elec-
trical installations for trailer towing.
PARKTRONIC is deactivated for the rear area
when you establish an electrical connection
between your vehicle and a trailer. If you use an
adapter for the socket, remove it from the
socket after detaching the trailer. Otherwise,
PARKTRONIC remains deactivated for the rear
area.
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.

Notes on trailer towing
Important safety notes
GWARNING
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.
GWARNING
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.
GWARNING
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 pro-
vided by the manufacturers of the trailer cou-
pling 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.
A trailer which is incorrectly coupled to the tow-ing vehicle could break away. A correctly cou-
pled trailer must be positioned horizontally
behind the towing vehicle.
Ensure that the following weights are not excee-
ded:
Rthe permissible noseweight
Rthe permissible trailer load
Rthe permissible rear axle load of the towing
vehicle
Rthe maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
Rthe permissible gross combination weight rat-
ing
The applicable permissible values that may not
be exceeded can be found:
Rin your vehicle documents
Ron the type plates for the trailer tow hitch
Ron the type plates for the trailer
Ron the vehicle identification plate
(Ypage 276)
Where the values differ, the lowest is valid.
You will find values approved by the manufac-
turer on the identification plates and those for
the towing vehicle in the "Permissible trailer
loads and trailer drawbar noseweights" section
(
Ypage 158).
Your vehicle behaves differently with a trailer
than without one.
The vehicle/trailer combination:
Ris heavier
Ris restricted in its acceleration and gradient-
climbing capability
Rhas an increased braking distance
Ris more susceptible to strong crosswinds
Rrequires more sensitive steering
Rhas 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 any further explanation of the
information contained in the Operator's Manual, please contact an authorized Sprinter dealer.
General notes
RObserve the legally prescribed maximum
speed for vehicle/trailer combinations in the
relevant country, state or Canadian province.Before setting off, check the vehicle docu-
ments of the your trailer to find out the per-
missible maximum speed.
This reduces the risk of accidents.
RInstall 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 availabil-
ity, mounting and installation of the trailer
electrics is available at any qualified specialist
workshop.
RThe trailer coupling is one of the most impor-
tant vehicle parts with regard to road safety.
The notes on operation, care and mainte-
nance issued by the manufacturer should be
observed.
RThe bumpers of your vehicle are not suitable
for installing detachable trailer couplings.
RDo not attach rented trailer tow hitches or
other detachable trailer tow hitches to the
bumper.
RMinimize 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 noseweig hts” se
c-
tion (Ypage 158).
iThe height of the ball neck changes accord-
ing to the load on the vehicle. If this is case,
use a trailer with a height-adjustable 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 vehicle/
trailer combinations in the relevant country,
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 con-
sume more fuel.
On long, steep downhill slopes you must select
shift range 3,2 or 1in good time.

iThis also applies if cruise control is activa-
ted.
This enables you to utilize the engine's braking
effect and you do not need to brake so heavily to
keep the correct speed. This relieves the load on
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:
XDo not accelerate.
XDo not counter-steer.
XBrake if necessary.
iYou can reduce the risk of the trailer swing-
ing and rocking by retrofitting anti-roll bars or trailer stability programs. More information is
available from your authorized Sprinter
Dealer.
RMaintain a greater distance than you would
when driving without towing a trailer.
RAvoid sudden braking. Apply the brakes gen-
tly at first to allow the trailer brake to overrun.
Then, increase the brake force quickly.
RThe figures for the gradient climbing capabil-
ities 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
Trailer coupled ready for use
XMake sure the selector lever of the automatic
transmission is in position P.
XApply the vehicle's parking brake.
XClose all doors.
XPosition the trailer horizontally behind your
vehicle.
iThe height of the ball neck changes accord-
ing to the load on the vehicle. In this case, use
a trailer with a height-adjustable trailer draw-
bar.
XCouple the trailer.
XEstablish all electrical and other connections to the trailer. When doing so, hook the break-
away cable of the trailer into eyelet :on the
ball coupling.
XRemove the objects that are preventing the
trailer from rolling, e.g. wheel chocks.
XRelease the trailer parking brake.
iThe subharness of the vehicle has a cable
connection to the brake lamp indicator lamp.
Observe the maximum permissible trailer
dimensions (width and length).
Most federal states and all Canadian provinces
require by law:
Rsafety chains between the towing vehicle and the trailer. The chains should be cross-wound
under the trailer drawbar. They must be fas-
tened 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.
Ra separate brake system for certain types of
trailer.
Ra safety shut-off for braked trailers. Find out
the specific requirements according to the
applicable laws.
If the trailer becomes detached from the tow-
ing vehicle, the safety feature triggers the
trailer brakes.
Towing a trailer
There are numerous legal requirements con-
cerning the towing of a trailer, e.g. speed restric-tions.
Many states require a separate functional brak-
ing system for your trailer once a certain weight
limit is exceeded. For your safety, it is recom-
mended to use a separate functional braking
system on any towed vehicle.
Make sure your vehicle/trailer combination
complies with local laws. This not only means
where you live, but also anywhere you are driv-
156Towing a trailer
Driving and parking

ing to. Information is available from the police
and local authorities.
Observe the following when towing a trailer:
RPractice 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.
RBefore 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
RAdjust the exterior mirrors to provide an
unobstructed view of the rear section of the
trailer.
RIf the trailer is equipped with an individual
braking system, check before each journey
whether the brakes are functioning correctly.
RIf 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.
RSecure the load on the trailer according to the
applicable specifications and current stand-
ards on securing loads (
Ypage 215).
RWhen driving with a trailer, check at regular
intervals that the load is secured and that the
brakes and lights are working.
RBear in mind that the handling will be less
stable when towing a trailer than when driving
without one. Avoid sudden steering move-
ments.
RThe vehicle/trailer combination is heavier,
accelerates more slowly and has a decreased
gradient climbing capability and a long er
brak

ing distance.
It is more susceptible to crosswinds and
requires cautious steering.
RIf possible, do not brake suddenly, but rather
moderately at first so that the trailer can acti-
vate its brakes. Then increase the force on the
brake pedal.
RIf the automatic transmission repeatedly
shifts between gears when driving on inclines, restrict the shift range. Select shift range
4,3,
2 or 1.
Driving in a low gear and at a low speed
reduces the risk of damaging the engine.
RWhen 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 instal-
led, the trailer brakes.
RIf the coolant temperature increases dramat-
ically 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.
RWhen overtaking, pay particular attention to
the extended length of your vehicle/trailer
combination.
Due to the length of your vehicle/trailer com-
bination you need an additional distance
before you can return to your original lane.
Uncoupling a trailer
GWARNING
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 rebounding of the overrun
brake.
XMake sure the selector lever of the automatic
transmission is in position P.
XApply the parking brake of the vehicle.
XClose all doors.
XApply the parking brake of the trailer.
XIn addition, secure the trailer against rolling
away with a wheel chock or similar object.
XRemove 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 vehicle
weight of 11030 lbs (5003 kg), the permissi-
ble 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
lead to damage to the drivetrain, to the trans-
mission or to the trailer tow hitch.
If the vehicle or the trailer is fully laden, the
relevant value for the permissible gross vehi-
cle 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. If the trailer is equipped with a separate functional braking system, then
the maximum gross trailer weight is 5000 lbs
(2268 kg) or 7500 lbs (3402 kg).
GWARNING
If you tow a trailer without a separate func-
tional braking system and a gross trailer
weight (GTW) of more than 1635 lbs (750 kg),
then the vehicle brake system may overheat.
This increases the braking distance and the
brake system may even fail. There is an
increased risk of accident and injury, possibly
even fatal.
Always use a trailer with a separate functional
braking system when towing a trailer with a
gross trailer weight (GTW) of more than
1635 lbs (750 kg).
The maximum permissible trailer drawbar nose-
weight 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 maximum permissible gross combination
weight is vehicle-specific and equipment-
dependent. When driving with a trailer, you should not
exceed the maximum permitted gross combi-
nation weight rating (GCWR).
The permissible values, which must not be
exceeded, can be found in your vehicle docu-
ments and on the trailer tow hitch type plates for
the trailer and the vehicle (
Ypage 276). The
basic values approved by the manufacturer can
also be found in the "Technical data" section
(
Ypage 288). If the values vary, the lowest
value always applies.
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.
