364 STARTING AND OPERATING
Sand
Soft sand is very difficult to travel through with full tire
pressure. When crossing soft, sandy spots in a trail, main-
tain your vehicle's momentum and do not stop. The key to
driving in soft sand is using the appropriate tire pressure,
accelerating slowly, avoiding abrupt maneuvers and main-
taining the vehicle's momentum. If you are going to be
driving on large soft sandy areas or dunes, reduce your tire
pressure to a minimum of 15 psi (103 kPa) to allow for a
greater tire surface area. Reduced tire pressure will drasti-
cally improve your traction and handling while driving on
the soft sand, but you must return the tires to normal air
pressure before driving on pavement or other hard sur-
faces. Be sure you have a way to reinflate the tires prior to
reducing the pressure.
CAUTION!
Reduced tire pressures may cause tire unseating 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 proceeding, 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 steering system
loading which could cause you to loose control of your
vehicle.
