Driving In Water - Hummer H2 2010 Owner's Manual

Driving in Water

WARNING:
Driving through rushing water can be dangerous.
Deep water can sweep your vehicle downstream
and you and your passengers could drown. If it is
only shallow water, it can still wash away the
ground from under your tires, and you could lose
traction and roll the vehicle over. Do not drive
through rushing water.
Heavy rain can mean flash flooding, and flood waters
demand extreme caution.
Find out how deep the water is before driving through it.
Do not try it if it is deep enough to cover the wheel
hubs, axles, or exhaust pipe
through. Deep water can damage the axle and other
vehicle parts. The vehicle is capable of depths up to
50 cm (20 inches). Know how to judge whether the
water is deeper than this before proceeding into it.
you probably will not get
If the water is not too deep, drive slowly through it. At
faster speeds, water splashes on the ignition system
and the vehicle can stall. Stalling can also occur if the
tailpipe is under water. If the tailpipe is under water, the
engine will not start. When going through water,
remember that when the brakes get wet, it might take
longer to stop. See Driving in Rain and on Wet Roads
on page 5 31.
After Off-Road Driving
Remove any brush or debris that has collected on the
underbody, chassis, or under the hood. These
accumulations can be a fire hazard.
After operation in mud or sand, have the brake linings
cleaned and checked. These substances can cause
glazing and uneven braking. Check the engine and oil
coolers for mud accumulation. Thoroughly and carefully
clean these devices to allow proper cooling. Check the
body structure, steering, suspension, wheels, tires, and
exhaust system for damage and check the fuel lines
and cooling system for any leakage.
The vehicle requires more frequent service due to
off-road use. Refer to the Maintenance Schedule for
additional information.
