CAUTION:
o Never connect a trailer brake system
directly to the vehicle brake system.
o When towing a trailer on steep grades
(in excess of 6%) pay close attention
to the engine coolant temperature
gauge to ensure the engine does not
overheat. If the needle of the coolant
temperature gauge moves across the
dial towards "H" (HOT), pull over and
stop as soon as it is safe to do so, and
allow the engine to idle until it cools
down. You may proceed once the
engine has cooled sufficiently.

Safety Chains
Should the hitch connection between your
car and the trailer or vehicle you are towing
fail, the trailer or vehicle could wander
dangerously across other lanes of traffic
and ultimately leave the roadway. To
eliminate this potentially dangerous
situation, safety chains, attached between
your car and the trailer or towed vehicle,
are required in most states.

Trailer Weight Limit
Tongue Load Total Trailer Weight
o Keep the tongue load 10% of the total
trailer load.
o
Tongue load
x 100 = 10% (MAX)
Total trailer weight
o Tongue loads can be increased or de-
creased by re-distributing the load in
the trailer.
This can be verified by checking the
total weight of the loaded trailer and
then checking the load on the tongue.
NOTE:
1. Never load the trailer with more weight
in the back than in the front. About
60% of the trailer load should be in the
front half on the trailer and the
remaining 40% in the rear.

Gross Axle Weight
2. The total gross vehicle weight with
trailer must not exceed the Gross
Vehicle Weight Rating (GVWR) shown
on the vehicle identification plate (see

weight is the combined weight of the
vehicle, driver, all passengers and
their luggage, cargo, hitch, trailer
tongue load and other optional
equipment.
