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. 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 {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, you should 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.

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
