Driving In Snow, Mud And Sand; Hill Climbing - Jeep Cherokee 2015 Owner's Manual

486 STARTING AND OPERATING
Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine, transmission, Power Trans-
fer Unit and Rear Drive Module) to assure they have not
been contaminated. Contaminated fluids and lubricants
(milky, foamy in appearance) should be flushed/changed
as soon as possible to prevent component damage.

Driving 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 4WD system to the appropriate terrain
mode, using 4WD LOW if necessary. Refer to "Four-
Wheel Drive Operation" in "Starting And Operating" for
further information. 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.
Avoid abrupt downshifts on icy or slippery roads because
engine braking may cause skidding and loss of control.

Hill Climbing

NOTE: Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission to a
lower gear and shift the 4WD System to 4WD LOW. Use
first gear and 4WD LOW 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 imme-
diately apply the brakes. Restart the engine and shift to
REVERSE. Back slowly down the hill allowing the compres-
sion braking of the engine to help regulate your speed. If the
brakes are required to control vehicle speed, apply them
lightly and avoid locking or skidding the tires.
