washer fluid HUMMER H2 2006 Owners Manual

Windshield Wipers
You control the windshield wipers by turning the band
with the wiper symbol on it.
8(Mist):For a single wiping cycle, turn the band to
mist. Hold it there until the wipers start. Then let go. The
wipers will stop after one wipe. If you want more
wipes, hold the band on mist longer.
N(Delay):You can set the wiper speed for a long or
short delay 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 band past
the delay settings.
1(High Speed):For high-speed wiping, turn the
band further, to the second solid band past the
delay settings.
9(Off):To stop the wipers, move the band to off.
Be sure to clear ice and snow from the wiper blades
before using them. If they’re frozen to the windshield,
carefully loosen or thaw them. If your blades do become
worn or damaged, get new blades or blade inserts.
Windshield Washer
{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.
LQ(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 the preset speed.
_(Heated Washer Fluid):If your vehicle is equipped
with the heated washer system, approximately
ve seconds after turning on your vehicle, it will be in
Standby mode. Heated windshield uid can spray
for three to six seconds to the windshield when the
washer uid paddle is used. The heated uid is
discharged by pushing the normal wash paddle in the
vehicle. Standby mode is activated every time the
vehicle is turned on.
3-9

To activate Automatic mode for de-icing, press the
heated washer switch. The indicator light starts to ash
at a one second rate. Once the washer uid is
heated, approximately 25 seconds, it is sprayed on the
windshield. This cycle will repeat four times
(approximately every six seconds) and then the unit will
return to Standby mode. Pressing the heated washer
uid button at any time during this cycle will stop
the Automatic mode and return it to Standby. Automatic
mode is recommended while the vehicle is parked.
In the case of a rapidly ashing light indicator on the
heated washer switch, it may be necessary to wait for up
to one minute for the light to stop ashing, then cycle
the ignition.
Rear Window Wiper/Washer (SUV)
If your vehicle has a rear
window washer/wiper, the
control knob is located
on the instrument panel
to the left of the
steering wheel.
{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.
To turn the rear wiper on, turn the knob to either 1 or 2.
For long delayed wiping, turn the knob to 1. For short
delayed wiping, turn the knob to 2.
9(Off):To turn the wiper off, turn the knob to
this symbol.
=(Washer Fluid):To wash the window, press the
knob with this symbol.
The rear window washer uses the same uid reservoir
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.

CHARGING SYSTEM FAILURE
On some vehicles, if there is a problem with the
generator and battery charging system, this message
will appear on the DIC, a chime will sound and the
charging system light on the instrument panel cluster
will come on. SeeCharging System Light on page 3-34
andVoltmeter Gage on page 3-34for more information.
Driving with this problem could drain your battery.
Turn off all unnecessary accessories. Stop and turn off
the vehicle as soon as it is safe to do so. Have the
electrical system checked by your dealer immediately.
CHECK OIL LEVEL
If the oil level in the vehicle is low, this message will
appear on the DIC. Check the oil level and correct it as
necessary. You may need to let the vehicle cool or
warm up and cycle the ignition to be sure this message
will clear. Once the problem is corrected, pressing
any of the four DIC buttons or the trip odometer reset
stem will clear this message from the DIC display. This
message will clear itself after 10 seconds until the
next ignition cycle.
CHECK WASHER FLUID
If the washer uid level is low, this message will appear
on the DIC. Adding washer uid will clear the message.
SeeWindshield Washer Fluid on page 5-34for more
information. Pressing any of the four DIC buttons or the
trip odometer reset stem will clear it from the DIC
display. This message will clear itself after 10 seconds
until the next ignition cycle.
DRIVER DOOR AJAR
If the driver’s door is not fully closed and the vehicle is
in a drive gear, this message will appear on the
display and you will hear a chime. Stop and turn off the
vehicle, check the door for obstacles, and close the
door again. Check to see if the message still appears on
the DIC. Pressing any of the four DIC buttons or the
trip odometer reset stem will clear the message from the
DIC display.
3-49

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?
Highway Hypnosis
Is there actually such a condition as highway hypnosis?
Or is it just plain falling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or whatever.
There is something about an easy stretch of road with
the same scenery, along with the hum of the tires on the
road, the drone of the engine, and the rush of the
wind against the vehicle that can make you sleepy. Do
not let it happen to you! If it does, your vehicle can
leave the road in less than a second, and you could
crash and be injured.
What can you do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:
Make sure your vehicle is well ventilated, with a
comfortably cool interior.
Keep your eyes moving. Scan the road ahead and
to the sides. Check your mirrors and your
instruments frequently.
If you get sleepy, pull off the road into a rest,
service, or parking area and take a nap, get some
exercise, or both. For safety, treat drowsiness
on the highway as an emergency.

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
Your vehicle has a message that comes on when the
washer uid is low. The message is displayed for
15 seconds at the start of each ignition cycle if the uid
is low. When the CHECK WASHER FLUID message
is displayed, you will need to add washer uid to
the windshield washer uid reservoir. SeeDIC Warnings
and Messages on page 3-48for more information.
Open the cap with the
washer symbol on it. Add
washer uid until the
tank is full. SeeEngine
Compartment Overview on
page 5-12for reservoir
location.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.
5-34

Engine Oil Level Check
Check the engine oil level and add the proper oil
if necessary. SeeEngine Oil on page 5-14for
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. SeeEngine
Coolant on page 5-24for 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. SeeTires on page 5-53for further
details. Check to make sure the spare tire is stored
securely. SeeChanging a Flat Tire on page 5-70.
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. SeeTire Inspection and Rotation on
page 5-61.
