34 STARTING AND OPERATING
Simultaneous Brake And Throttle
Operation
Many off-road driving conditions require the
simultaneous use of the brake and throttle
(two-footed driving). When climbing rocks, logs, or
other stepped objects, using light brake pressure
with light throttle will keep the vehicle from jerking
or lurching. This technique is also used when you
need to stop and restart a vehicle on a steep
incline.
Driving In Snow, Mud And Sand
SNOW
In heavy snow or for additional control and traction
at slower speeds, select SNOW mode from the
TRX modes. This will optimize traction and stability
in these conditions. Do not shift to a lower gear
than necessary to maintain headway. Over-revving
the engine can spin the wheels and traction will be
lost. If you start to slow to a stop, try turning your
steering wheel no more than a quarter turn quickly
back and forth, while still applying throttle. This will
allow the tires to get fresh traction and help
maintain your momentum.
MUD
Deep mud creates a great deal of suction around
the tires and is very difficult to get through. Select
SAND/MUD mode from the TRX modes for
optimum traction and maneuverability in these
conditions. If you start to slow to a stop, try turning
your steering wheel no more than a quarter turn
quickly back and forth for additional traction. Mud
holes pose an increased threat of vehicle damage
and getting stuck. They are normally full of debris
from previous vehicles getting stuck. As a good
practice before entering any mud hole, get out and
determine how deep it is, if there are any hidden
obstacles and if the vehicle can be safely
recovered if stuck.
SAND
Select MUD/SAND from the TRX modes. Soft sand
is very difficult to travel through with full tire
pressure. When crossing soft, sandy spots in a
trail, maintain 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 maintaining 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 drastically 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 surfaces. Be
sure you have a way to reinflate the tires prior to
reducing the pressure.
CAUTION!
On icy or slippery roads, do not downshift at high
engine RPM or vehicle speeds, because engine
braking may cause skidding and loss of control.
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. The
optionally available Beadlock wheels are
recommended to avoid unseating the tire from
the wheel when running very low tire pressures.
