330 STARTING AND OPERATING
Flowing Water
If the water is swift flowing and rising (as in storm run-off)
avoid crossing until the water level recedes and/or the flow
rate is reduced. If you must cross flowing-water, avoid
depths in excess of 9 inches (22 cm). The flowing water can
erode the streambed causing your vehicle to sink into deeper
water. Determine exit point(s) that are downstream of your
entry point to allow for drifting.
Standing Water
Avoid driving in standing water deeper than 16 inches (40.5 cm),
and reduce speed appropriately to minimize wave effects.
Maximum speed in 16 inches (40.5 cm) of water is less than 5 mph
(8 km/h).
(Trailhawk only): Avoid driving in standing water deeper
than 19 inches (48 cm), and reduce speed appropriately to
minimize wave effects. Maximum speed in 19 inches (48 cm)
of water is less than 5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine, transmission, Power Transfer
Unit, and Rear Drive Module) to ensure 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 Opera
-
tion” 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.
