2007 HUMMER H3 window

Compass Operation
Press the compass/temperature button once
briey to turn the display on or off.
Compass Calibration
The compass may need calibration if one of the
following occurs:
If CAL is displayed while driving in the vehicle.
After approximately ve seconds, the display
does not show a compass heading, N for
North, for example, there may be a strong
magnetic eld interfering with the compass.
Such interference may be caused by a
magnetic antenna mount, magnetic note pad
holder, or a similar magnetic item.
The compass does not display the correct
heading and the compass zone variance
is set correctly.In order to calibrate, CAL must be displayed in the
mirror compass windows. If CAL is not displayed,
push in the compass/temperature button for
approximately nine seconds or until CAL is
displayed.
The compass can be calibrated by driving the
vehicle in circles at 5 mph (8 km/h) or less until the
display reads a direction.
Compass Variance
The mirror is set in zone eight upon leaving the
factory. It will be necessary to adjust the compass
to compensate for compass variance if the vehicle
is outside zone eight. Under certain circumstances,
as during a long distance cross-country trip, it will
be necessary to adjust for compass variance.
Compass variance is the difference between earth’s
magnetic north and true geographic north. If not
adjusted to account for compass variance, your
compass could give false readings.

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.
159

Dome Lamp Override
E(Dome Lamp Override):You can use the
dome override button, located below the exterior
lamps control, to set the dome and footwell
lamps to come on automatically when a door is
opened, or to remain off. To turn the lamps
off, press the button into the in position. With the
button in this position, the dome lamps will
remain off when the doors are open. To return
the lamps to automatic operation, press the
button again and return it to the out position.
With the button in this position, the dome lamps
will come on when you open a door.
Exit Lighting
With exit lighting, the interior lamps will come
on when you remove the key from the ignition.
The lamps will not come on if the dome override
button is pressed in.
Reading Lamps
Your vehicle has reading lamps. Press the button
located next to the lamp to turn them on or off.
These lamps will not come on with the dome lamps.
Electric Power Management
The vehicle has Electric Power Management (EPM)
that estimates the battery’s temperature and state
of charge. It then adjusts the voltage for best
performance and extended life of the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage, you may
see the voltage move up or down. This is normal.
If there is a problem, an alert will be displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to
produce all the power that is needed for very
high electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged into
accessory power outlets.
168

Recirculation is available in the bi-level, and vent
modes. Recirculation is not available while in
oor, oor/defog and defrost mode. If recirculation
is selected in these modes, the indicator will
ash three times indicating it is not available in
that mode. When the recirculation mode is turned
on, the air conditioning will turn on automatically.
H(Vent):Turn the right knob on the control
panel to this mode to direct air to the instrument
panel outlets.
\(Bi-Level):Turn the right knob on the control
panel to this mode to direct air to the instrument
panel outlets, and the remaining air to the
oor outlets and the defroster and side window
outlets. Cooler air is directed to the upper outlets
and warmer air to the oor outlets.
[(Floor):Turn the right knob on the control
panel to this mode to direct air to the oor outlets,
side window outlets, and defroster. Recirculation
is not available in this mode.
Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate
control system is used properly. There are
two modes to clear fog or frost from your
windshield and side windows. Use the defog mode
to clear the windows of fog or moisture and
warm the passengers. Use the defrost mode to
remove fog or frost from the windshield more
quickly. For best results, clear all snow and ice
from the windshield before defrosting.
/(Floor/Defog):Turn the right knob on the
control panel to this mode to direct the air to
the windshield, the side window outlets, and to
the oor outlets. When you select this mode, the
system runs the air conditioning system unless
the outside temperature is near freezing or below.
Recirculation is not available in this mode.
172

0(Defrost):Turn the right knob on the control
panel to this mode to direct most of the air to the
windshield, and the side window outlets. When
you select this mode, the system runs the air
conditioning system unless the outside temperature
is near or below freezing. Recirculation is not
available in this mode.
Do not drive the vehicle until all the windows
are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window when
the key is in the ignition and turned to ON.
=(Rear Defogger):Press the right knob on the
control panel to turn the rear window defogger
on or off. First press of this button will activate
the rear window defogger for 15 minutes and
each subsequent activation lasts seven and
one-half minutes.
Notice:Do not use anything sharp on the
inside of the rear window. If you do, you could
cut or damage the warming grid, and the repairs
would not be covered by your warranty. Do not
attach a temporary vehicle license, tape, a decal
or anything similar to the defogger grid.
Outlet Adjustment
Use the air outlets located in the center and
on the side of your instrument panel to direct
the airow.
Your vehicle has air outlets that allow you to
adjust the direction and amount of airow inside
the vehicle. Move the louvers up or down to
change the direction of the airow. Use the
thumbwheel under the outlets to change the
direction of the airow from left to right.
Operation Tips

Enable recirculation mode for maximum
air conditioning performance.
Clear away any ice, snow or leaves from the
air inlets at the base of the windshield that
may block the ow of air into your vehicle.
Use of non-GM approved hood deectors
may adversely affect the performance of
the system.
Keep the path under the front seats clear
of objects to help circulate the air inside
of your vehicle more effectively.
