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
obstacles. 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 en-
sures 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 vehi-
cle's mobility. Approach these obstacles at a 45-degree
angle and let each tire go through the obstacle indepen-
dently. 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.
