Crossing Obstacles (Rocks And Other High Points) - Jeep 2013 Wrangler Owner's Manual

CAUTION!
Reduced tire pressures may cause tire un-
seating and total loss of air pressure. To
reduce the risk of tire unseating, while at a
reduced tire pressure, reduce your speed
and avoid sharp turns or abrupt maneuvers.
Crossing Obstacles (Rocks And
Other High Points)
While driving off-road, you will encounter many
types of terrain. These varying types of terrain
bring different types of obstacles. Before pro-
ceeding, review the path ahead to determine
the correct approach and your ability to safely
recover the vehicle if something goes wrong.
Keeping a firm grip on the steering wheel, bring
the vehicle to a complete stop and then inch the
vehicle forward until it makes contact with the
object. Apply the throttle lightly while holding a
light brake pressure and ease the vehicle up
and over the object.

WARNING!
Crossing obstacles can cause abrupt steer-
ing 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. Deter-
mining the correct path can be extremely diffi-
cult when you are confronting many obstacles.
In these cases have someone guide you over,
through, or around the obstacle. Have the per-
son 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 undercar-
riage 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 under-
carriage.
• 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.
