Crossing Large Rocks
When approaching large rocks, choose a path which en-
sures you drive over the largest 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.
Crossing Logs
To cross a log, approach it at a slight angle (approximately
10 to 15 degrees). This allows one front tire to be on top of
the log while the other just starts to climb the log. While
climbing the log, modulate your brake and accelerator to
avoid spinning the log out from under your tires. Then
ease the vehicle off the log using your brakes.
CAUTION!
Do not attempt to cross a log with a greater diameter
than the running ground clearance or the vehicle will
become high centered.
