2007 HUMMER H3 washer fluid

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. See
Retained Accessory Power (RAP) on page 103.
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.

Rear Window Wiper/Washer
This knob is located
on the instrument
panel below the
climate controls.
Z(Rear Wiper):To turn the rear wiper on,
turn the knob to either 1 or 2. For a slower
wiping speed, turn the knob to 1. For a faster
wiping speed, turn the knob to 2
0 (Off):To turn the wiper off, turn the knob to
this symbol.
=(Washer Fluid):To wash and wipe the window,
press the button within the knob with this symbol.
The rear window washer uses the same uid bottle
as the windshield washer. However, the rear
window washer will run out of uid before the
windshield washer. If you can wash your windshield
but not your rear windows, check the uid level.
Cruise Control
With cruise control, you can maintain a speed
of about 25 mph (40 km/h) or more without
keeping your foot on the accelerator. This can
really help on long trips. Cruise control does not
work at speeds below about 25 mph (40 km/h).
9(Off):This position
turns the system off.
R(On):This position activates the system.
+ (Resume/Accelerate):Move the lever to this
symbol to make the vehicle accelerate or resume
to a previously set speed.
rT(Set):Press this button to set the speed.

Once you are moving on the freeway, make
certain you allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to
the proper lane well in advance. If you miss
your exit, do not, under any circumstances, stop
and back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite
sharply. The exit speed is usually posted.
Reduce your speed according to your
speedometer, not to your sense of motion.
After driving for any distance at higher speeds,
you may tend to think you are going slower
than you actually are.
Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested.
If you must start when you are not fresh — such
as after a day’s work — do not plan to make
too many miles that rst part of the journey.
Wear comfortable clothing and shoes you can
easily drive in.Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it needs
service, have it done before starting out. Of course,
you will nd experienced and able service experts
in GM dealerships all across North America. They
will be ready and willing to help if you need it.
Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir
full? Are all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you
checked all levels?
Lamps:Are they all working? Are the lenses
clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough
for long-distance driving? Are the tires
all inated to the recommended pressure?
Weather Forecasts:What is the weather
outlook along your route? Should you
delay your trip a short time to avoid a major
storm system?
Maps:Do you have up-to-date maps?

Engine Oil
Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. In order to get an accurate reading,
the oil must be warm and the vehicle must be
on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 322
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several
minutes to drain back into the oil pan. If you
do not do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it with a paper
towel or cloth, then push it back in all the
way. Remove it again, keeping the tip down,
and check the level.
323

How to Check Power Steering Fluid
1. Turn the key off and let the engine
compartment cool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and wipe the dipstick with a
clean rag.
4. Replace the cap and completely tighten it.
5. Then remove the cap again and look at
the uid level on the dipstick.
The level should be between the ADD and FULL
marks. If necessary, add only enough uid to
bring the level up to the proper range.
What to Use
To determine what kind of uid to use, see
Recommended Fluids and Lubricants on page 440.
Always use the proper uid. Failure to use the
proper uid can cause leaks and damage hoses
and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer uid, be sure
to read the manufacturer’s instructions before
use. If you will be operating your vehicle in an area
where the temperature may fall below freezing,
use a uid that has sufficient protection against
freezing.
Adding Washer Fluid
Open the cap with the
washer symbol on it.
Add washer uid
until the tank is full. See
Engine Compartment
Overview on page 322
for reservoir location.
346

Notice:
When using concentrated washer uid,
follow the manufacturer’s instructions
for adding water.
Do not mix water with ready-to-use washer
uid. Water can cause the solution to
freeze and damage your washer uid tank
and other parts of the washer system.
Also, water does not clean as well
as washer uid.
Fill your washer uid tank only
three-quarters full when it is very cold.
This allows for expansion if freezing
occurs, which could damage the tank if it
is completely full.
Do not use engine coolant (antifreeze) in
your windshield washer. It can damage
your washer system and paint.
Brakes
Brake Fluid
Your brake master
cylinder reservoir is
lled with DOT-3 brake
uid. SeeEngine
Compartment Overview
on page 322for the
location of the reservoir.
There are only two reasons why the brake uid
level in the reservoir might go down. The rst
is that the brake uid goes down to an acceptable
level during normal brake lining wear. When
new linings are put in, the uid level goes back
up. The other reason is that uid is leaking out of
the brake system. If it is, you should have your
brake system xed, since a leak means that
sooner or later your brakes will not work well, or
will not work at all.
347

At Each Fuel Fill
It is important to perform these underhood checks
at each fuel ll.
Engine Oil Level Check
Check the engine oil level and add the proper oil
if necessary. SeeEngine Oil on page 323for
further details.
Notice:It is important to check your oil
regularly and keep it at the proper level.
Failure to keep your engine oil at the proper
level can cause damage to your engine
not covered by your warranty.
Engine Coolant Level Check
Check the engine coolant level and add
DEX-COOL®coolant mixture if necessary. See
Engine Coolant on page 335for further details.
Windshield Washer Fluid Level Check
Check the windshield washer uid level in
the windshield washer uid reservoir and add
the proper uid if necessary.
At Least Once a Month
Tire Ination Check
Visually inspect your vehicle’s tires and make
sure they are inated to the correct pressures.
Do not forget to check the spare tire. See
Ination - Tire Pressure on page 375. Check to
make sure the spare tire is stored securely.
SeeChanging a Flat Tire on page 391.
Tire Wear Inspection
Tire rotation may be required for high mileage
highway drivers prior to the Engine Oil Life
System service notication. Check the tires for
wear and, if necessary, rotate the tires. See
Tire Inspection and Rotation on page 381.
