9. To avoid a “bow wave,” drive slowly into water.

10.Drive at 3 mph to 4 mph (5 kph to 6 kph) while fording. Keep engine speed up to at least 1,000 RPM. Slow

vehicle with brake, if necessary, while maintaining 1,000 RPM.

CAUTION

If you accidentally drive into water more than 4 ft (1.22 m) deep, do not stop engine while it

is under water. Exhaust pressure will prevent water from entering engine through the

exhaust system. If engine stops while it is under water, do not try to restart. Damage to

engine may occur. Have vehicle towed from water immediately. If you must stop vehicle

while engine is under water, shift transmission to high, apply and hold brakes, and keep

engine speed at 1,000 RPM. DO NOT attempt to operate vehicle after submerging until field

maintenance has checked it. Failure to comply may damage vehicle.
