2007 HUMMER H2 battery location

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 97.
If you are still having trouble, see your dealer
or a qualied technician for service.
Remote Keyless Entry (RKE)

Matching Transmitter(s) to Your Vehicle
Each RKE transmitter is coded to prevent another
transmitter from unlocking your vehicle. If a
transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring
any remaining transmitters with you when you go to
your dealer. When the dealer matches the
replacement transmitter to your vehicle, any
remaining transmitters must also be matched. Once
your dealer has coded the new transmitter, the lost
transmitter will not unlock your vehicle. Each
vehicle can have a maximum of four transmitters
matched to it.
Battery Replacement
Under normal use, the battery in your
RKE 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.

OnStar®service cannot work unless your vehicle
is in a place where OnStar®has an agreement
with a wireless service provider for service in that
area. OnStar
®service also cannot work unless
you are in a place where the wireless service
provider OnStar
®has hired for that area
has coverage, network capacity and reception
when the service is needed, and technology that
is compatible with the OnStar
®service. Not all
services are available everywhere, particularly in
remote or enclosed areas, or at all times.
OnStar
®service that involves location information
about your vehicle cannot work unless GPS
satellite signals are unobstructed and available in
that place as well.
Your vehicle must have a working electrical
system (including adequate battery power) for the
OnStar
®equipment to operate. There are other
problems OnStar®cannot control that may prevent
OnStar®from providing OnStar®service to you
at any particular time or place. Some examples are
damage to important parts of your vehicle in an
accident, hills, tall buildings, tunnels, weather
or wireless phone network congestion.
Your Responsibility
You may need to increase the volume of your
radio to hear the OnStar®advisor. If the light next
to the OnStar®buttons is red, this means that
your system is not functioning properly and should
be checked by a dealer. If the light appears
clear (no light is appearing), your OnStar
®
subscription has expired. You can always press
the OnStar®button to conrm that your OnStar®
equipment is active.

Battery
Your vehicle has a maintenance free battery.
When it is time for a new battery, get one that has
the replacement number shown on the original
battery’s label. We recommend an ACDelco
®
replacement battery. SeeEngine Compartment
Overview on page 402for battery location.
Warning:Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harm.
Wash hands after handling.
Vehicle Storage
If you are not going to drive your vehicle for
25 days or more, remove the black, negative (−)
cable from the battery. This will help keep
your battery from running down.
{CAUTION:
Batteries have acid that can burn you and
gas that can explode. You can be badly
hurt if you are not careful. SeeJump
Starting on page 432for tips on working
around a battery without getting hurt.
431

To avoid the possibility of the vehicles rolling,
set the parking brake rmly on both vehicles
involved in the jump start procedure. Put
an automatic transmission in PARK (P) or a
manual transmission in NEUTRAL before
setting the parking brake.
Notice:If you leave your radio or other
accessories on during the jump starting
procedure, they could be damaged. The repairs
would not be covered by your warranty.
Always turn off your radio and other
accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles.
Unplug unnecessary accessories plugged into
the cigarette lighter or accessory power
outlets. Turn off the radio and all lamps that
are not needed. This will avoid sparks
and help save both batteries. And it could
save your radio!4. Open the hoods and locate the positive (+)
and negative (−) terminal locations of the
other vehicle.
Your vehicle has a remote positive (+) jump
starting terminal and a remote negative (−)
jump starting terminal. You should always use
these remote terminals instead of the
terminals on the battery.
The remote positive (+)
terminal is located near
the engine accessory
drive bracket. On some
vehicles, the terminal
may be covered
by a red plastic cover.
To access the
remote positive (+)
terminal, open
the cover, if equipped.
433

The remote negative (−)
terminal is located
on the engine accessory
drive bracket and is
marked GND (Ground).
SeeEngine Compartment Overview on
page 402for more information on the location
of the remote terminals.
{CAUTION:
Using a match near a battery can cause
battery gas to explode. People have been
hurt doing this, and some have been
blinded. Use a ashlight if you need
more light.
Be sure the battery has enough water.
You do not need to add water to the
battery installed in your new vehicle.
But if a battery has ller caps, be sure the
right amount of uid is there. If it is low,
add water to take care of that rst. If you
do not, explosive gas could be present.
Battery uid contains acid that can burn
you. Do not get it on you. If you
accidentally get it in your eyes or on your
skin, ush the place with water and get
medical help immediately.
