Driving tips
8-32
F) Front of vehicle
The tongue load can be adjusted by proper distribu-
tion of the load in the trailer. Never load the trailer
with more weight in the back than in the front;
approximately 60 percent of the trailer load should
be in the front and approximately 40 percent in the
rear. Also, distribute the load as evenly as possible
on both the left and right sides.
Be sure that all cargo is firmly secured to prevent a
change in weight distribution while driving.
WARNING
If the trailer is loaded with more weight in the
back of trailer’s axle than in the front, the load
is taken off the rear axle of the towing vehicle.
This may cause the rear wheels to skid, espe-
cially during braking or when vehicle speed is
reduced during cornering, resulting in over-
steer, spin out and/or jackknifing.
J Trailer hitches
Choose a proper hitch for your vehicle and trailer.
WARNING
Never drill the frame or under-body of your
vehicle to install a commercial trailer hitch. If
you do, dangerous exhaust gas, water or mud
may enter the passenger compartment
through the drilled hole. Exhaust gas contains
carbon monoxide, a colorless and odorless
gas which is dangerous, or even lethal, if
inhaled. Also, drilling the frame or under-body
of your vehicle could cause deterioration of
strength of your vehicle and cause corrosion
around the drilled hole.
