be loaded by referring to t he following instructions.

Tongue Weight
If using a weight distributing hi tch when towing, return the front
axle to the same weight as b efore the trailer connection.
If front axle weight cannot be measured directly, measure the
front fender height above the front axle before connection. Adjust
weight distributing hitch torque until front fender is returned to the
same height as b efore connection.
Do not reduce front fender heigh t below original measurement.
The gross trailer weight, gross axle weight and tongue weight
can be measured with platform sca les found at a highway weigh-
ing station, building supply company, trucking company, junk

3164-6. Driving tips
Off-road precautions
●Specific design charac teristics give it a higher center of grav ity than
ordinary passenger cars. This vehi cle design feature causes this
type of vehicle to be more likel y to rollover. And, utility vehicles
have a significantly higher rollover rate than other types of v ehicles.
● An advantage of the higher ground clearance is a better view of the
road allowing you to anticipate problems.
● It is not designed for cornering at the same speeds as ordinary pas-
senger cars any more than low-s lung sports cars are designed to
perform satisfactorily under o ff-road conditions. Therefore, sh arp
turns at excessive speeds may c ause the vehicle to rollover.
This vehicle belongs to the utility vehicle class, which has
higher ground clearance and narrower tread in relation to the
height of its center of gravity to make it capable of performin g in
a wide variety of of f-road applications.
