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.
