202 STARTING AND OPERATING
additional low speed pulling power is needed.
Vehicle speeds in excess of 25 mph (40 km/h)
should be avoided when in 4L.
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, shift the transmission into a low
gear and the transfer case into 4L if necessary. 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 1/4 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. You
should use DRIVE, with the transfer case in the 4L
position to maintain your momentum. If you start to
slow to a stop, try turning your steering wheel no
more than a 1/4 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
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.
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
CAUTION!
Do not use 4L when operating the vehicle on dry
pavement. Driveline hardware damage can
result.
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.
