washer fluid HUMMER H2 2007 Owners Manual

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. Push the paddle to
spray washer uid on the windshield. The wipers
will clear the window and then either stop or
return to the preset speed.
_(Heated Washer Fluid):If your vehicle has
the heated windshield washer uid system, it
is used to help clear ice, snow, tree sap, or bugs
from your windshield.To activate Automatic mode for de-icing, press the
heated washer button located above the
headlamp switch on the left side of the dash.
Pushing the heated washer uid button will
activate the heated windshield washer uid
system. This activation will initiate four heated
wash/wipe cycles. The rst heated wash/wipe
cycle may take up to 40 seconds to occur,
depending on outside temperature. After the rst
wash/wipe cycle, it may take up to 20 seconds
for each of the remaining cycles. The heated
windshield washer uid system may be turned off
at any time by pushing the button again prior
to the completion of 4 wash/wipe cycles.
When the heated windshield washer uid system
is activated under certain outside temperature
conditions, steam may ow out of the washer
nozzles for a short period of time before washer
uid is sprayed. This is a normal condition.
A message will be displayed on the Driver
Information Center (DIC) when the washer uid is
low. SeeDIC Warnings and Messages on
page 226.

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, this message displays, a chime
sounds, and the charging system light on the
instrument panel cluster comes on if there
is a problem with the generator and battery
charging system. SeeCharging System Light on
page 209andVoltmeter Gage on page 210
for more information. Driving with this problem
could drain the 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
This message displays if the oil level in the vehicle
is low. 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 make sure this
message clears. Once the problem is corrected,
press any of the DIC buttons, or the trip stem,
to acknowledge this message and clear it from the
DIC display. This message clears itself after
10 seconds until the next ignition cycle.
CHECK WASHER FLUID
This message displays if the windshield washer
uid level is low. Adding windshield washer uid to
the windshield washer uid reservoir clears the
message. SeeWindshield Washer Fluid on
page 426for more information. Press any of the
DIC buttons, or the trip stem, to acknowledge
this message and clear it from the DIC display.
This message clears itself after 10 seconds
until the next ignition cycle.
DRIVER DOOR AJAR
This message displays and a chime sounds if the
driver’s door is not fully closed and the vehicle
is in a drive gear. Stop and turn off the vehicle,
check the door for obstructions, and close the door
again. Check to see if the message still appears
on the DIC. Press any of the DIC buttons, or
the trip stem, to acknowledge this message and
clear it from the DIC display.

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?

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 226for more information.
Open the cap with the
washer symbol on it.
Add washer uid
until the tank is full. See
Engine Compartment
Overview on page 402
for 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.

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 404for
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 415for 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 456. Check to
make sure the spare tire is stored securely.
SeeChanging a Flat Tire on page 468.
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 457.
