For more information on tire size designation, load and
speed rating, refer to "Tire Labeling". See an authorized
Sprinter Dealer for information on tested and
recommended rims and tires for summer and winter
operation. They can also offer advice concerning tire
service and purchase.
WARNING!
Using tires other than those approved by the vehi-
cle manufacturer can have detrimental effects,
such as
poor handling characteristics
increased noise
increased fuel consumption
Moreover, tires and rims not approved by the
vehicle manufacturer may, under load, exhibit
dimensional variations and different tire
deformation characteristics that could cause them
to come into contact with the vehicle body or axle
parts. Damage to the tires or the vehicle may be
the result.
WARNING!
Do not use a tire, wheel size or rating other than
that specified for your Sprinter vehicle. Some
combinations of unapproved tires and wheels
may change suspension dimensions and perfor-
mance characteristics, resulting in changes to
steering, handling, and braking of your Sprinter
vehicle. This can cause unpredictable handling
and stress to steering and suspension compo-
nents. You could lose control and have an accident
resulting in serious injury or death. Use only the
tire and wheel sizes with load ratings approved
for your Sprinter vehicle, refer to "Tire and Load-
ing Information". Never use a tire with a smaller
load index or speed index or capacity, other than
what was originally equipped on your Sprinter
vehicle. Using a tire with a smaller load index
could result in tire overloading and failure. You
could lose control and have an accident.
Failure to equip the vehicle with tires having
adequate speed capability can result in sudden
tire failure and loss of vehicle control.
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.
