WARNING!
Crossing obstacles can cause abrupt steering system
loading which could cause you to loose control of your
vehicle.
Using A Spotter
There are many times where it is hard to see the obstacle or
determine the correct path. Determining the correct path can
be extremely difficult when you are confronting many obsta-
cles. In these cases have someone guide you over, through, or
around the obstacle. Have the person stand a safe distance in
front of you where they can see the obstacle, watch your tires
and undercarriage, and guide you through.
Crossing Large Rocks
When approaching large rocks, choose a path which ensures
you drive over the largest of them with your tires. This will
lift your undercarriage over the obstacle. The tread of the tire
is tougher and thicker than the side wall and is designed to
take the abuse. Always look ahead and make every effort to
cross the large rocks with your tires.
CAUTION!
• Never attempt to straddle a rock that is large enough to
strike your axles or undercarriage.
• Never attempt to drive over a rock which is large
enough to contact the door sills.
Crossing A Ravine, Gully, Ditch, Washout Or Rut
When crossing a ravine, gully, ditch, washout or a large rut,
the angled approach is the key to maintaining your vehicle's
mobility. Approach these obstacles at a 45-degree angle and
let each tire go through the obstacle independently. You
need to use caution when crossing large obstacles with steep
sides. Do not attempt to cross any large obstacle with steep
sides at an angle great enough to put the vehicle at risk of a
rollover. If you get caught in a rut, dig a small trench to the
right or left at a 45-degree angle ahead of the front tires. Use
the removed dirt to fill the rut ahead of the turnout you just
created. You should now be able to drive out following the
trench you just created at a 45-degree angle.
WARNING!
There is an increased risk of rollover when crossing an
obstacle, at any angle, with steep sides.
