36 STARTING AND OPERATING
When To Use 4WD Low Range
When off-road driving, shift into 4WD Low 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 55 mph (88 km/h) should be avoided
when in 4WD Low range.
CAUTION!
Do not use 4WD Low range when operating
the vehicle on dry pavement. Driveline
hardware damage can result.
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 4WD
Low 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 a fresh "bite" and help maintain your
momentum.
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.
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 4WD Low 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.
