wiper blades HUMMER H3 2008 Owners Manual

Windshield Wipers
You control the windshield wipers by turning the band
with the wiper symbol on it.
8(Mist):Turn the band to mist for a single wiping
cycle. Hold it there until the wipers start. Then let
go. The wipers will stop after one wipe. Hold the band
on mist longer, if more wipes are needed.
N(Delay):The wiper speed can be set for long
or short delays between wipes. This can be very useful
in light rain or snow. Turn the band to choose the
delay time. The closer to the top of the lever, the shorter
the delay.
6(Low Speed):For steady wiping at low speed,
turn the band away from you to the rst solid position
past the delay settings.
1(High Speed):For high-speed wiping, turn the
band to the second solid position past the delay settings.
9(Off):Move the band to off, to stop the wipers.
Be sure to clear ice and snow from the wiper blades
before using them. If they are frozen to the windshield,
carefully loosen or thaw them. If your blades do
become worn or damaged, get new blades or blade
inserts.Windshield wipers work in all power modes, except
when set to LOCK. After the engine is turned off, wipers
will work in Retained Accessory Power (RAP) mode
until a door is opened. SeeRetained Accessory Power
(RAP) on page 2-20.
Windshield Washer
L(Washer Fluid):There is a paddle marked with the
windshield washer symbol at the top of the multifunction
lever. To spray washer uid on the windshield, push the
paddle. The wipers will clear the window and then either
stop or return to your preset speed.
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.

Before Leaving on a Long Trip
To prepare your vehicle for a long trip, consider having
it serviced by your dealer/retailer before departing.
Things to check on your own include:
Windshield Washer Fluid:Reservoir full? Windows
clean — inside and outside?
Wiper Blades:In good shape?
Fuel, Engine Oil, Other Fluids:All levels checked?
Lamps:Do they all work and are lenses clean?
Tires:Are treads good? Are tires inated to
recommended pressure?
Weather and Maps:Safe to travel? Have up-to-date
maps?
Highway Hypnosis
Always be alert and pay attention to your surroundings
while driving. If you become tired or sleepy, nd a
safe place to park your vehicle and rest.
Other driving tips include:
Keep the vehicle well ventilated.
Keep interior temperature cool.
Keep your eyes moving — scan the road ahead
and to the sides.
Check the rearview mirror and vehicle instruments
often.
Hill and Mountain Roads
Driving on steep hills or through mountains is different
than driving on at or rolling terrain. Tips for driving
in these conditions include:
Keep your vehicle serviced and in good shape.
Check all uid levels and brakes, tires, cooling
system, and transmission.
Going down steep or long hills, shift to a
lower gear.

Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for wear
and cracking. SeeScheduled Maintenance on page 6-4
for more information.
Replacement blades come in different types and are
removed in different ways. For proper type and length,
seeNormal Maintenance Replacement Parts on
page 6-14.

Windshield, Backglass, and Wiper
Blades
Clean the outside of the windshield and backglass with
glass cleaner.
Clean the rubber blades using a lint free cloth or paper
towel soaked with windshield washer uid or a mild
detergent. Wash the windshield thoroughly when you
clean the blades. Bugs, road grime, sap and a buildup of
vehicle wash/wax treatments may cause wiper streaking.
Replace the wiper blades if they are worn or damaged.
Wipers can be damaged by:
Extreme dusty conditions
Sand and salt
Heat and sun
Snow and ice, without proper removal
Aluminum or Chrome-Plated Wheels
and Trim
Your vehicle may have either aluminum or
chrome-plated wheels.
Keep the wheels clean using a soft clean cloth with mild
soap and water. Rinse with clean water. After rinsing
thoroughly, dry with a soft clean towel. A wax may then
be applied.Notice:Chrome wheels and other chrome trim may
be damaged if you do not wash your vehicle after
driving on roads that have been sprayed with
magnesium, calcium or sodium chloride. These
chlorides are used on roads for conditions such as
ice and dust. Always wash your vehicle’s chrome
with soap and water after exposure.
Notice:If you use strong soaps, chemicals,
abrasive polishes, cleaners, brushes, or cleaners
that contain acid on aluminum or chrome-plated
wheels, you could damage the surface of the
wheel(s). The repairs would not be covered by your
warranty. Use only approved cleaners on aluminum
or chrome-plated wheels.
The surface of these wheels is similar to the painted
surface of your vehicle. Do not use strong soaps,
chemicals, abrasive polishes, abrasive cleaners,
cleaners with acid, or abrasive cleaning brushes on
them because you could damage the surface. Do not
use chrome polish on aluminum wheels.

(d)Inspect wiper blades for wear, cracking, or
contamination. Clean the windshield and wiper blades, if
contaminated. Replace wiper blades that are worn or
damaged. See Windshield Wiper Blade Replacement on
page 5-52 and Windshield, Backglass, and Wiper
Blades on page 5-97 for more information.
(e)Make sure the safety belt reminder light and safety
belt assemblies are working properly. Look for any
other loose or damaged safety belt system parts. If you
see anything that might keep a safety belt system
from doing its job, have it repaired. Have any torn or
frayed safety belts replaced. Also see Checking
the Restraint Systems on page 1-69.
(f)Lubricate all key lock cylinders, hood latch assembly,
secondary latch, pivots, spring anchor, release pawl,
rear compartment hinges, outer swing-gate handle pivot
points, rear door detent link, roller mechanism,
swing-gate handle pivot points, latch bolt, fuel door
hinge, locks, and folding seat hardware. More frequent
lubrication may be required when exposed to a
corrosive environment. Applying silicone grease on
weatherstrips with a clean cloth will make them
last longer, seal better, and not stick or squeak.(g)Check vent hose at transfer case for kinks and
proper installation.
(h)Change automatic transmission fluid and filter if the
vehicle is mainly driven under one or more of these
conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police, or delivery
service.
(i)Drain, flush, and refill cooling system. This service
can be complex; you should have your dealer/retailer
perform this service. See Engine Coolant on page 5-27
for what to use. Inspect hoses. Clean radiator,
condenser, pressure cap, and filler neck. Pressure test
the cooling system and pressure cap.
(j)A fluid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired and
the fluid level checked. Add fluid if needed.
(k)Visually inspect belt for fraying, excessive cracks, or
obvious damage. Replace belt if necessary.
