280 STARTING AND OPERATING
Driving Across An Incline
If at all possible, avoid driving across an incline.
If it is necessary, know your vehicle's abilities.
Driving across an incline places more weight
on the downhill wheels, which increases the
possibilities of a downhill slide or rollover. Make
sure the surface has good traction with firm and
stable soils. If possible, transverse the incline at
an angle heading slightly up or down.
WARNING!
Driving across an incline increases the risk of
a rollover, which may result in severe injury.
If You Stall Or Begin To Lose Headway
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 brake.
Restart the engine and shift into REVERSE.
Back slowly down the hill allowing engine
braking to control the descent and apply your
brakes, if necessary, but do not allow the tires
to lock.
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,
which may result in severe injury. Always back
carefully straight down a hill in REVERSE.
Never back down a hill in NEUTRAL using only
the vehicle brakes. Never drive diagonally
across a hill, always drive straight up or down.
Driving Through Water
Extreme care should be taken crossing any type
of water. Water crossings should be avoided, if
possible, and only be attempted when
necessary in a safe, responsible manner. Only
drive through areas which are designated and
approved. Tread lightly and avoid damage to the
environment. Know your vehicle's abilities and
be able to recover it if something goes wrong.
Never stop or shut a vehicle off when crossing
deep water unless you ingested water into the
engine air intake. If the engine stalls, do not
attempt to restart it. Determine if it has ingested
water first. The key to any crossing is low and
slow. Shift into first gear (manual transmission),
or DRIVE (automatic transmission), with the
transfer case in the 4L (Low) position and
proceed very slowly with a constant slow speed
of {3 to 5 mph (5 to 8 km/h) maximum} and
light throttle. Keep the vehicle moving; do not
try to accelerate through the crossing. After
crossing any water higher than the bottom of
the axle differentials, inspect all of the vehicle
fluids for signs of water ingestion.
CAUTION!
Water ingestion into the axles, transmission,

transfer case, engine or vehicle interior can
occur if you drive too fast or through too deep
of water. Water can cause permanent
damage to engine, driveline or other vehicle
components, and your brakes will be less
effective once wet and/or muddy.
When driving through water, do not exceed

5 mph (8 km/h). Always check water depth
before entering as a precaution, and check
all fluids afterward. Driving through water
may cause damage that may not be
covered by the New Vehicle Limited
Warranty.
