STARTING AND OPERATING 265
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. You
should only drive through areas which are
designated and approved. You should tread
lightly and avoid damage to the environment.
You should know your vehicle's abilities and be
able to recover it if something goes wrong. You
should 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. You want to use FIRST gear in
4WD LOW and proceed very slowly with a
constant slow speed (3-5 mph [5–8 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, you should
inspect all of the vehicle fluids for signs of water
ingestion.
Before You Cross Any Type Of Water – As you
approach any type of water you need to
determine if you can cross it safely and
responsibly. If necessary, get out and walk
through the water or probe it with a stick. You
need to be sure of its depth, approach angle,
current and bottom condition. Be careful of
murky or muddy waters, check for hidden
obstacles. Make sure you will not be
intruding on any wildlife and you can recover
the vehicle if necessary. The key to a safe
crossing is the water depth, current and
bottom conditions. On soft bottoms the
vehicle will sink in, effectively increasing the
water level on the vehicle. Be sure to
consider this when determining the depth
and the ability to safely cross.
Crossing Puddles, Pools, Flooded Areas Or
Other Standing Water – Puddles, pools,
flooded or other standing water areas
normally contain murky or muddy waters.
These water types normally contain hidden
obstacles and make it difficult to determine
an accurate water depth, approach angle,
and bottom condition. Murky or muddy water
holes are where you want to hook up tow
straps prior to entering. This makes for a
faster, cleaner and easier vehicle recovery.
If you are able to determine you can safely
cross, than proceed using the low and slow
method.
Crossing Ditches, Streams, Shallow Rivers Or
Other Flowing Water – Flowing water can be
extremely dangerous. Never attempt to cross
a fast running stream or river even in shallow
water. Fast moving water can easily push
your vehicle downstream sweeping it out of
control. Even in very shallow water, a high
current can still wash the dirt out from
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.
CAUTION!
Muddy waters can reduce the cooling system
effectiveness by depositing debris onto the
radiator.
