Jeep 2004 Liberty - Manual (Page 237)

In Snow, Mud and Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the transfer case to 4L or 4 LO if necessary.
Don’t shift to a lower gear than necessary to maintain
headway. Over-revving the engine can spin the wheels
and traction will be lost.
Do not downshift on icy or slippery roads, because
engine braking may cause skidding and loss of control.
Hill Climbing
Before climbing a steep hill, shift the transmission to a
lower gear and shift the transfer case to 4L or 4 LO. Use
first gear and 4L or 4 LO for very steep hills.
If you stall or begin to lose headway while climbing a
steep hill, allow your vehicle to come to a stop and
immediately apply the brakes. Restart the engine and
shift to R (Reverse). Back slowly down the hill allowing
the compression braking of the engine and transmission
to help regulate your speed. If the brakes are required to
control vehicle speed, apply them lightly and avoid
locking or skidding the tires.
WARNING!
If the engine stalls or you lose headway or cannot
make it to the top of a steep hill or grade, never
attempt to turn around. To do so may result in
tipping and rolling the vehicle. Always back care-
fully straight down a hill in R (Reverse) gear. Never
back down a hill in N (Neutral) using only the brake.
