Accessory Weight
The combined weight (in excess of those standard
items which may be replaced) of automatic
transmission, power steering, power brakes, power
windows, radio, and heater, to the extent that these
items are available as factory-installed equipment
(whether installed or not).
Air Pressure
The amount of air inside the tire pressing outward on
each square inch of the tire. Air pressure is expressed
in pounds per square inch (psi), or kilopascal (kPa) or
bars.
Aspect Ratio
Dimensional relationship between tire section height
and section width expressed in percentage.
Bar
Another metric unit for air pressure. There are 14.5038
pounds per square inch (psi) to 1 bar; there are 100
kilopascals (kPa) to 1 bar.
202 STARTING AND OPERATING
Kilopascal (kPa)
Themetric unit for air pressure. There are 6.9 kPa to 1
psi; another metric unit for air pressure is bars. There
are 100 kilopascals (kPa) to 1 bar.
Maximum Load Rating
The maximum load in kilograms and pounds that can
be carried by the tire.
Maximum Loaded Vehicle Weight
The sum of curb weight, accessory weight, vehicle
capacity weight and production options weight.
Maximum Tire Inflation Pressure
This number is the greatest amount of air pressure that
should ever be put in the tire under normal driving
conditions.
Normal Occupant Weight
The number of occupants the vehicle is designed to
seat, multiplied by 68 kilograms (150 lbs).
Occupant Distribution
The distribution of occupants in a vehicle at their
designated seating positions.Production Options Weight
The combined weight of those installed regular
production options weighing over 5 lbs (2.3 kilograms)
in excess of those standard items which they replace,
not previously considered in curb weight or accessory
weight, including heavy duty brakes, ride levelers,
roof rack, heavy duty battery, and special trim.
PSI (Pounds per Square Inch)
A standard unit of measure for air pressure. Another
metric unit for air pressure is bars or kilopascal (kPa).
Recommended Tire Inflation Pressure
Recommended tire inflation pressure listed on Tire
and Loading Information placard on the driver’s door
B-pillar for normal driving conditions. Provides best
handling, tread life and riding comfort.
Rim
A metal support for a tire or a tire and tube assembly
upon which the tire beads are seated.
Sidewall
The portion of a tire between the tread and the bead.
204 STARTING AND OPERATING
Vehicle Capacity Weight
Rated cargo and luggage load plus 68 kilograms (150
lbs) times the vehicle’s designated seating capacity.
Vehicle Maximum Load on the Tire
Load on an individual tire that is determined by
distributing to each axle its share of the maximum
loaded vehicle weight and dividing it by two.
Rotating Tires
Tires on the front and rear axles of vehicles operate at
different loads and perform different steering, driving
and braking functions. For these reasons, they wear at
unequal rates, and develop irregular wear patterns.
These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on On/Off
Road type tires. Rotation will increase tread life, help tomaintain mud, snow, and wet traction levels, and
contribute to a smooth, quiet ride.
If applicable to your vehicle's tire configuration, tires
can be rotated according to the tire manufacturer’s
recommended intervals in the tire manufacturer’s
warranty pamphlet located in your vehicle literature
portfolio. If none is available, tires should be rotated
every 10000 miles (16000 km), or sooner if necessary,
according to the degree of tire wear.
The same rotation (spinning) direction must be
maintained when fitted, see "Direction of Rotation".
Rotate tires before the characteristic tire wear pattern
becomes visible (shoulder wear on front tires and
treadcenter wear on rear tires).
The reasons for any rapid or unusual wear should be
corrected prior to rotation being performed.
Thoroughly clean the mounting face of wheels and
brake disks, i.e. the inner side of the wheels/tires,
during each rotation. Check for and ensure proper tire
inflation pressure, refer to "Recommended Tire
Inflation Pressure".
WARNING!
Rotate front and rear wheels only if the tires are of
the same dimension.

capacity of your vehicle, called the Gross Vehicle
Weight Rating (GVWR). The GVWR includes the
weight of the vehicle, all occupants, fuel and cargo.
The Certification Label also tells you about the front
and rear axle weight capacity, called the Gross Axle
Weight Rating (GAWR). The GAWR is the total
allowable weight that can be carried by a single axle
(front or rear). Never exceed the GVWR or GAWR
for either the front axle or rear axle.
Following is a discussion on how to work with the
information contained on the two placards with
regards to loading your Sprinter vehicle.Tire and Loading Information
WARNING!
Do not overload the tires by exceeding the speci-
fied load limit as indicated on the Tire and Load-
ing Information placard on the driver’s door B-
pillar. Overloading the tires can overheat them,
possibly causing a blowout. Overloading the tires
can also result in handling or steering problems,
or brake failure.
Overloading of tires is dangerous. Overloading
can cause tire failure, affect vehicle handling, and
increase the stopping distance. Use tires of the
recommended load capacity for the vehicle. Never
overload them.
The vehicle maximum load on the tire must not
exceed the load carrying capacity of the tire on
your vehicle. You will not exceed the tire’s load
carrying capacity if you adhere to the loading
conditions, tire size and cold tire inflation
pressures specified on the Tire and Loading
Information placard and this section.
222 STARTING AND OPERATING
Trailer Hitches (Optional)
Only install a trailer hitch receiver approved for your
vehicle. For information on availability and
installation, please see your authorized Sprinter
Dealer.
The bumpers on your vehicle are not designed for use
with clamp-type hitches. Do not attach rental hitches
or other bumper-type hitches to them.
To reduce the possibility of damage, remove the hitch
ball adaptor from the receiver when not in use.
Electrical Connections (Optional)
The Sprinter is available with a variety of pre-installed
conditions (lines and turn signal 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 authorized Sprinter
Dealer.
In order to prevent possible damage to the vehicle’s
electrical system by incorrectly installing the trailer
wiring plug, we recommend having the harness
connected at an authorized Sprinter Dealer.Vehicle and Trailer Weights and Ratings

224 STARTING AND OPERATING
Checking Weights of Vehicle and Trailer
To assure that the tow 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.
Check the vehicle’s front and rear Gross Axle Weight
(GAW), the GTW and TW. The values as measured
must not be exceeded, according to the weight listed
under “Vehicle and trailer weight and ratings”.
Attaching a Trailer
Please observe maximum permitted trailer dimensions
(width and length).
Most states and all Canadian provinces require safety
chains between your tow vehicle 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 permit turning corners.
Most states and all Canadian provinces require a
separate brake system at various trailer weights.
WARNING!
Do not connect a trailer brake system (if trailer is
so equipped) directly to the vehicle’s hydraulic
brake system as your vehicle is equipped with an-
tilock brakes. If you do, neither the vehicle’s
brakes nor the trailer’s brakes will function prop-
erly. This could cause an accident resulting in
property damage, injury or death to you or others.
The provided vehicle electrical wiring harness for
trailer towing has a brake signal wire for hook-up
to a brake controller.
Most states and all Canadian provinces require 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 vehicle.
You should consider using a trailer sway control
system. For further information see your
authorized Sprinter Dealer.

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 authorities.
Before you start driving with the trailer, check the
trailer hitch, break-away switch, safety chains,
electrical connections, lighting and tires. Also adjust
the mirrors to permit unobstructed view beyond rear
of 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 the brakes are
working 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.
Always secure items in the trailer to prevent load shifts
while driving.Take into consideration that when towing a trailer, the
handling characteristics are different and less stable
from those when operating the vehicle without a
trailer. It is important to avoid sudden maneuvers. The
vehicle and trailer combination is heavier, and
therefore is limited in acceleration 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 practice turning, stopping
and backing up in an area which is free from traffic.
If possible, do not brake abruptly, but rather engage
the brake slightly at first to permit the trailer to activate
its brake. Then increase the braking force.
