Transporting your vehicle by rail may be
subject to certain restrictions or require
special measures to be taken in some
countries due to varying tunnel heights
and loading standards.
You can obtain information at any
authorized Sprinter Dealer.Trailer hitches*
Only install a trailer hitch receiver ap-
proved for your vehicle. For information on
availability and installation, please see
your authorized Sprinter Dealer.
The bumpers on your vehicle are not de-
signed for use with clamp-type hitches. Do
not attach rental hitches or other bumper-
type hitches to them.
To reduce the possibility of damage, re-
move the hitch ball adaptor from the re-
ceiver when not in use.Electrical connections*
The Sprinter is available with a variety of
pre-installed conditions (lines and turn sig-
nal indicator and brake module installed
and / or not installed). Make sure that the
correct trailer hitch receiver kit is used. For
further information, please see your autho-
rized Sprinter Dealer.
In order to prevent possible damage to the
vehicle’s electrical system by incorrectly
installing the trailer wiring plug, we recom-
mend having the harness connected at an
authorized Sprinter Dealer.Rail transportTrailer towingWarning

Vehicle and trailer weights and ratings
Gross Vehicle Weight Rating (GVWR) is the
maximum permissible vehicle weight:
\48550 lbs (3880 kg) for vehicle model
type 2500
\49990 lbs (4530 kg), or 11030 lbs
(5003 kg) for vehicle model type 3500

!
CAUTION
Cargo vans with a long wheelbase of
170.3 in (4325 mm) and an overall
vehicle length of 289.1 in (7344 mm)
have a reduced GTW and TWR.
iThe GVWR and the front/rear GAWR of
your vehicle are indicated on the
certification label.!
CAUTION
For vehicle model type 3500, the allow-
able GCWR is less than the combined
maximum weight of the GVWR and the
GTW. Exceeding the GCWR can cause
damage to the drive train, the transmis-
sion, or the trailer hitch*.
Thus, the permissible values for GVWR
and/or the GTW are reduced when
either the trailer or the vehicle is fully
laden. you may therefore only partly
load the vehicle and/or the trailer.

*optional equipmentWhen loading the vehicle and/or a trailer,
you should observe that the GCWR of your
vehicle is not exceeded.
You must distribute total weight between
the vehicle and the trailer such that neither
the permissible GTW, nor the GVWR and
front/rear GAWR , nor the TWR are
exceeded.The tongue weight at the hitch ball must be
added to the GVWR to prevent exceeding
your Sprinter tow vehicle’s rear GAWR.
Maximum permissible values are listed in
the table above and on the safety compli-
ance certification labels for the vehicle and
for the trailer to be towed. The lowest value
listed must be selected when determining
how the vehicle and trailer are loaded.To assure that the vehicle and trailer are in
compliance with the maximum permissible
weight limits, and to know the actual
weights, have the loaded vehicle-trailer
combination (tow vehicle including driver,
passengers and cargo, trailer fully loaded)
weighed on a commercial scale.Sprinter type

Attaching a trailer
Please observe the maximum permitted
trailer dimensions (width and length).
Most states and all Canadian provinces re-
quire safety chains between your tow vehi-
cle and the trailer. The chains should be
crisscrossed under the trailer tongue. They
must be attached to the hitch receiver, and
not to the vehicle’s bumper or axle. Be sure
to leave enough slack in the chains to per-
mit turning corners.Towing a trailer
There are many different laws, including
speed limit restrictions, having to do with
trailer towing. Make sure that your vehicle-
trailer combination will be legal, not only
for where you reside, but also for where
you will be driving. A good source for this
information can be the police or local au-
thorities.
Before you start driving with the trailer,
check the trailer hitch, break-away switch,
safety chains, electrical connections, light-
ing and tires. Also adjust the mirrors to
permit an unobstructed view beyond the
rear of the trailer.
If the trailer has electric brakes, start your
vehicle and trailer moving slowly, and then
apply only the trailer brake controller by
hand to be sure that the brakes are work-
ing properly.
When towing a trailer, check occasionally
to be sure that the load is secure, and that
lighting and trailer brakes (if so equipped)
are functioning properly.
iMost states and all Canadian provinces
require a separate brake system at var-
ious trailer weights.
Warning
G
Do not connect a trailer brake system (if
trailer is so equipped) directly to the vehi-
cle’s hydraulic brake system as your vehicle
is equipped with antilock brakes. If you do,
neither the vehicle’s brakes nor the trailer’s
brakes will function properly. This could
cause an accident resulting in property dam-
age, injury or death to you or others.
The provided vehicle electrical wiring har-
ness for trailer towing has a brake signal
wire for hook-up to a brake controller.
Most states and all Canadian provinces re-
quire a break-away switch on trailers with a
separate brake system. The switch activates
the trailer brakes in the possible event that
the trailer might separate from the tow vehi-
cle.
You should consider using a trailer sway
control system. For further information, see
your authorized Sprinter Dealer.

Always secure items in the trailer to pre-
vent load shifts while driving.
Take into consideration that when towing a
trailer, the handling characteristics are dif-
ferent and less stable from those when op-
erating the vehicle without a trailer. It is
important to avoid sudden maneuvers.
The vehicle and trailer combination is
heavier, and therefore is limited in acceler-
ation and climbing ability, and requires
longer stopping distances. It is more prone
to reacting to side wind gusts, and requires
more sensitive steering input.
In order to gain skill and an understanding
of the vehicle’s behavior, you should prac-
tice turning , st opping and backing up in a n
area which is free from traffic.
If possible, do not brake abruptly, but rath-
er engage the brake slightly at first to per-
mit the trailer to activate its brake. Then
increase the braking force.
Warning
G
Take into consideration that when towing a
trailer, the handling characteristics are dif-
ferent and less stable from those when op-
erating the vehicle without a trailer.
It is important to avoid sudden maneuvers.
Sudden maneuvers may lead to loss of con-
trol over the vehicle-trailer combination.
This could cause an accident resulting in
property damage or injury to you or others.!
CAUTION
If the transmission hunts between
gears on inclines, manually shift to a
lower gear (select
"4", "3", "2" or
"1").
A lower gear and reduction of speed re-
duces the chance of the engine over-
loading and / or overheating.
When going down a long hill, shift into
a lower gear and use the engine’s brak-
ing effect. Avoid riding the brakes, thus
overheating the vehicle and trailer
brakes.
If the engine coolant rises to an ex-
tremely high temperature (coolant tem-
perature needle approaching the red
zone) when the air conditioner is on,
turn off the air conditioner. Engine
coolant heat can be additionally vented
by opening the windows, switching the
climate control fan speed to high and
setting the temperature control to the
maximum hot position.
Extreme care must be exercised since
your vehicle with a trailer will require
additional passing distance ahead than
when driving without a trailer. Because
your vehicle and trailer is longer than
your vehicle alone, you will also need to
go much farther ahead of the passed
vehicle before you can return to your
lane.

Placard
For vehicles with a gross weight capacity
less than 10,000 lbs (4500 kg) only.
The tire and loading information placard is
located on the driver’s door B-pillar.Tire and loading information placard1Seating capacity
2Load limit informationSeating capacity
The seating capacity1 gives you impor-
tant information on the number of occu-
pants that can be in the vehicle. Observe
front and rear seating capacity.
Never let more people ride in the vehicle
than there are designated seating posi-
tions and seat belts available. Make sure
that everyone riding in the vehicle is cor-
rectly restrained with a separate seat belt.Load limit information
Locate the statement “The combined
weight of occupants and cargo should nev-
er exceed XXX kilograms or XXX lbs.” 2
on the tire and loading information plac-
ard. The combined weight of all occupants,
cargo/luggage and trailer tongue load (if
applicable) should never exceed the
weight referenced in that statement.
Steps for determining correct load limit
For vehicles with a gross weight capacity
less than 10,000 lbs (4500 kg) only.
The following steps have been developed
as required of all manufacturers under Title
49, Code of U.S. Federal Regulations, Part
575 pursuant to the “National Traffic and
Motor Vehicle Safety Act of 1966”.
iThe data shown on this placard is for il-
lustrative purposes only. The load limit
data and seating data are specific to
each vehicle and may vary from the
data shown in the illustration below.
Refer to the placard on your vehicle for
actual data specific to your vehicle.

Step 1
\1Locate the statement “The combined
weight of occupants and cargo should
never exceed XXX kg or XXX lbs.” on
your vehicle’s placard.
Step 2
\1Determine the combined weight of the
driver and passengers that will be
riding in your vehicle.
Step 3
\1Subtract the combined weight of the
driver and passengers from
XXX kilograms or XXX lbs.Step 4
\1The resulting figure equals the avail-
able amount of cargo and luggage load
capacity. For example, if the “XXX”
amount equals 1400 lbs and there will
be five 150 lbs passengers in your vehi-
cle, the amount of available cargo and
luggage load capacity is 650 lbs (1400-
750 (5 x150) = 650 lbs).
Step 5
\1Determine the combined weight of lug-
gage and cargo being loaded on the ve-
hicle. That weight may not safely
exceed the available cargo and luggage
load capacity calculated in step 4.Step 6 (if applicable)
\1If your vehicle will be towing a trailer,
load from your trailer will be trans-
ferred to your vehicle. Consult this
manual to determine how this reduces
the available cargo and luggage load
capacity of your vehicle.
The following table shows examples on
how to calculate total load, cargo load and
towing capacities with varying seating con-
figurations and number and size of occu-
pants. The following examples use a load
limit of 1500 lbs. This is for illustrative
purposes only. Make sure you are using
the actual load limit for your vehicle stated
on the vehicle’s tire and loading informa-
tion placard (\2page 206).
The higher the weight of all occupants, the
less cargo and luggage load capacity is
available.
