266 STARTING AND OPERATING
When To Use 4L Range
When off-road driving, shift into 4L for
additional traction and control on slippery or
difficult terrain, ascending or descending steep
hills, and to increase low speed pulling power.
This range should be limited to extreme
situations such as deep snow, mud, steep
inclines, or sand where additional low speed
pulling power is needed. Vehicle speeds in
excess of 25
mph (40 km/h) should be avoided
whe
n in 4L range.
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
tra
ction 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 quarter turn
quickly back and forth, while still applying
throttle. This will allow the tires to get a fresh
"bite" and help maintain your momentum.
Mud
Deep mud creates a great deal of suction
aro
und 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
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
Soft sand is very difficult to travel through with
ful
l 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!
Do not use 4L (Low) range 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.
