Before You Go Off-Roading
There are some things to do before you go out.
For example, be sure to have all necessary
maintenance and service work done. Check to make
sure all underbody shields (if so equipped) are properly
attached. Be sure you read all the information about
your four
- wheel - drive vehicle in this manual. Is there
enough fuel? Is the spare tire fully inflated? Are the
fluid levels up where they should be? What are the local
laws that apply to off
- roading where you’ll be driving?
If you don’t know, you should check with law
enforcement people in the area. Will you be on
someone’s private land? If so, be sure to get the
necessary permission.
Loading Your Vehicle for Off-Road Driving
There are some important things to remember about
how to load your vehicle.
D The heaviest things should be on the load floor and
forward of your rear axle. Put heavier items as far
forward as you can.
D Be sure the load is secured properly, so driving on
the off - road terrain doesn’t toss things around.
