2007 HUMMER H3 key battery

Changes or modications to this system by other
than an authorized service facility could void
authorization to use this equipment.
At times you may notice a decrease in operating
range. This is normal for any RKE system. If
the transmitter does not work or if you have to
stand closer to your vehicle for the transmitter to
work, try this:
Check the distance. You may be too far from
your vehicle. You may need to stand closer
during rainy or snowy weather.
Check the location. Other vehicles or objects
may be blocking the signal. Take a few steps
to the left or right, hold the transmitter
higher, and try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement”
underRemote Keyless Entry (RKE) System
Operation on page 89.
If you are still having trouble, see your dealer
or a qualied technician for service.
Remote Keyless Entry (RKE)
System Operation
You can lock and unlock the vehicle’s doors and
disarm or arm the theft-deterrent system from

Battery Replacement
Under normal use, the battery in the remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter
will not work at the normal range in any location.
If you have to get close to your vehicle before
the transmitter works, it is probably time to change
the battery.
Notice:When replacing the battery, use care
not to touch any of the circuitry. Static
from your body transferred to these surfaces
may damage the transmitter.To replace the battery, do the following:
1. Insert a coin, or similar object, in the slot
between the covers of the transmitter
housing. Gently pry the transmitter apart.
2. Remove and replace the battery with a
three-volt CR2032 or equivalent battery.
3. Align the covers and snap them together.
4. Check the operation of the transmitter.

Visor Vanity Mirror
Your vehicle has a vanity mirror located on the
driver’s and passenger’s visor.
Illuminated Visor Vanity Mirror
Your vehicle may have an illuminated vanity mirror
on both visors. Lift the cover on the mirror and
the lights will automatically come on.
Theft-Deterrent Systems
Vehicle theft is big business, especially in some
cities. Although your vehicle has a number of
theft-deterrent features, we know that nothing we
put on it can make it impossible to steal.
Content Theft-Deterrent
Your vehicle has a
content theft-deterrent
alarm system.To activate the content theft-deterrent system, do
the following:
1. Close all the doors.
2. Lock the doors with the remote keyless entry
transmitter. The security light, located on the
instrument panel cluster, will ash.
If the lock button on the remote keyless entry
transmitter is pressed, but a door is open,
the doors will lock, the lights may ash and the
horn may sound. Close the open door and
the alarm system will arm.
If a locked door is not opened using the remote
keyless entry transmitter, or by OnStar
®, the alarm
will go off. First, a pre-alarm will sound the horn
at reduced intensity for 10 seconds. Then, the front
turn signal lamps will ash for two minutes, and
the horn will sound for two minutes. The alarm will
then turn off to save battery power.
Starting the engine with the correct key will shut
off the pre-alarm or alarm at any time.
Remember, the theft-deterrent system will not
activate if you lock the doors with the key,
the manual door lock, or power door lock switch.

Notice:Using a tool to force the key from the
ignition switch could cause damage or break
the key. Use the correct key and turn the key
only with your hand. Make sure the key is all the
way in. If it is, turn the steering wheel left and
right while you turn the key hard. If none of this
works, then your vehicle needs service.
ACC (ACCESSORY) (B):This is the position in
which you can operate your electrical accessories
or items plugged into the accessory power
outlets. On automatic transmission vehicles, this
position unlocks the ignition. On manual
transmission vehicles, it unlocks the ignition and
steering wheel. Use this position if your vehicle
must be pushed or towed.
ON (C):This is the position that the switch returns
to after you start your engine and release the
switch. The switch stays in ON when the engine is
running. But even when the engine is not running,
you can use ON to operate the electrical
accessories and to display some instrument
panel cluster warning and indicator lights.The transmission is also unlocked in this position on
automatic transmission vehicles.
The battery could be drained if you leave the key in
the ACC or ON position with the engine off. You
may not be able to start your vehicle if the battery is
allowed to drain for an extended period of time.
START (D):This is the position that starts the
engine. When the engine starts, release the key.
The ignition switch returns to ON for driving.
When the engine is not running, ACC and ON
allows you to operate the electrical accessories,
such as the radio or items plugged into the
accessory power outlets.
A warning tone will sound if you open the driver’s
door when the ignition is in ACC or LOCK and
the key is in the ignition.
Key In the Ignition
Never leave your vehicle with the keys inside, as it
is an easy target for joy riders or thieves. If you
leave the key in the ignition and park your vehicle,
a chime will sound, when you open the driver’s
door. Always remember to remove your key from
the ignition and take it with you. This will lock
your ignition and transmission. Also, always
remember to lock the doors.
102

The battery could be drained if you leave the key
in the ignition while your vehicle is parked.
You may not be able to start your vehicle after it
has been parked for an extended period of time.
Retained Accessory Power (RAP)
Your vehicle has Retained Accessory Power (RAP)
which allows certain features of your vehicle to
continue working for up to 20 minutes after
the ignition key is turned to LOCK.
The radio, front wipers, power windows, and a
sunroof if your vehicle has one, will work when the
ignition key is in ON or ACC. Once the key is turned
from ON to LOCK, these features continue working
for up to 20 minutes or until a door is opened.
Starting the Engine
Place the transmission in the proper gear.
Automatic Transmission
Move your shift lever to PARK (P) or
NEUTRAL (N). Your engine will not start in
any other position -- this is a safety feature.
To restart when you are already moving, use
NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could
damage the transmission. Shift to PARK (P)
only when your vehicle is stopped.
Manual Transmission
The shift lever should be in the NEUTRAL position
and the parking brake engaged. Hold the clutch
pedal to the oor and start the engine. Your
vehicle will not start if the clutch pedal is not all
the way down. That is a safety feature.
Starting Procedure
1. With your foot off the accelerator pedal, turn
the ignition key to START. When the engine
starts, let go of the key. The idle speed will go
down as the engine gets warm. Do not race the
engine immediately after starting it. Operate
the engine and transmission gently to allow the
oil to warm up and lubricate all moving parts.
103

Your vehicle has a Computer-Controlled
Cranking System. This feature assists in
starting the engine and protects components.
If the ignition key is turned to the START
position, and then released when the engine
begins cranking, the engine will continue
cranking for a few seconds or until the vehicle
starts. If the engine does not start and the
key is held in START for many seconds,
cranking stoppes 15 seconds to prevent
cranking motor damage. To prevent gear
damage, this system also prevents cranking if
the engine is already running. Engine
cranking can be stopped by turning the ignition
switch to the ACC or LOCK position.
Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can
overheat and damage the cranking motor, and
drain the battery. Wait at least 15 seconds
between each try, to allow the cranking motor
to cool down.2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F
or−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator
pedal all the way to the oor and holding it
there as you hold the key in START for up to
a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the
cranking motor to cool down. When the engine
starts, let go of the key and accelerator.
If the vehicle starts briey but then stops
again, do the same thing. This clears the extra
gasoline from the engine. Do not race the
engine immediately after starting it. Operate
the engine and transmission gently until the oil
warms up and lubricates all moving parts.
Notice:Your engine is designed to work with
the electronics in your vehicle. If you add
electrical parts or accessories, you could
change the way the engine operates. Before
adding electrical equipment, check with your
dealer. If you do not, your engine might not
perform properly. Any resulting damage would
not be covered by your vehicle’s warranty.
104

Automatic Transmission Operation
The automatic transmission has a shift lever on
the console.
It features an electronic shift position indicator
within the instrument cluster. This display must be
powered anytime the shift lever is capable of
being moved out of PARK (P). This means that if
your key is turned off, but not in LOCK, there
will be a small current drain on your battery which
could discharge your battery over a period of
time. If you need to leave your key in the ignition
but not in LOCK for an extended period, it is
recommended that you disconnect the battery
cable from the battery to prevent discharging your
battery.
There are several different positions for your shift
lever.PARK (P):This position locks your rear wheels.
It is the best position to use when you start the
engine because your vehicle cannot move easily.
{CAUTION:
It is dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P)
with the parking brake rmly set. Your
vehicle can roll.
Do not leave your vehicle when the engine
is running unless you have to. If you have
left the engine running, the vehicle can
move suddenly. You or others could be
injured. To be sure your vehicle will not
move, even when you are on fairly level
ground, always set your parking brake and
move the shift lever to PARK (P).
SeeShifting Into Park (P) (Automatic
Transmission) on page 117. If you are
pulling a trailer, seeTowing a Trailer on
page 297.

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.
