battery replacement HUMMER H2 2006 Owners Manual

At times you may notice a decrease in range. This is
normal for any remote keyless entry 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” under
Remote Keyless Entry System Operation on
page 2-5.
If you are still having trouble, see your dealer or a
qualied technician for service.
Remote Keyless Entry System
Operation
You can lock and unlock your doors from about 3 feet
(1 m) up to 100 feet (30 m) away using the remote
keyless entry transmitter supplied with your vehicle.
K(Unlock):Press this
button once to unlock the
driver’s door. The
interior lamps will come
on. Pressing unlock again

Q(Lock):Press this button once to lock all of the
doors. Pressing lock again within three seconds
may cause the horn to chirp for lock conrmation. You
can choose different feedback options for each press
of the lock button. See “Lock Feedback” and “Unlock
Feedback” underDIC Vehicle Customization on
page 3-55for more information.
L(Panic):Press this button to sound the horn and
ash the headlamps and taillamps for up to 30 seconds.
Panic can be turned off by pressing the button again,
by waiting for 30 seconds, or by starting the vehicle.
Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry 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 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.

Before You Drive
The RSE system will play DVD, CD, and MP3 discs. You
can also connect an auxiliary device to the RSE system
to play games, watch videos, view photos, etc.
Notice:Normal operation for the RSE system may
be limited under extreme temperatures. Using
the RSE system during extreme temperatures may
cause damage to the system. Wait until the inside of
the vehicle is at a safe temperature range of
32°-140°F (0°-60°C) before using the system.
Headphones
Wireless Headphones
The RSE system may include two sets of wireless
headphones. Each headphone will have an L marked
on the left-side, for the left ear and an R marked on the
right-side, for the right ear. The L and R marks are to
show how the headphones should be worn.
OFF/ON (Power):The wireless headphones have an
OFF/ON power switch located on the left of the
earpiece. To use the headphones, turn the switch to
ON. An indicator light on the right earpiece of the
headphones will illuminate. If the light does not

the headphones to OFF when not in use.The headphones will shut off automatically to save the
battery power if the RSE system is shut off or if the
headphones are out of range of the transmitter window
for more than three minutes. The transmitter window
is located on the bottom edge of the monitor. If
you move too far forward or step out of the vehicle,
the headphones will lose the audio signal.
Channel Selector:The wireless headphones have a
channel selector switch located on the right earpiece.
The channel selector switches between Channel A and
Channel B. Since each monitor has the capability to
function as two independent sources through auxiliary
input, it is necessary to transmit audio signals on
separate channels. The driver’s side monitor is
designated as Channel A, and the passenger’s side as
Channel B. The Headphone channel selector switch
must be set to the appropriate channel according to the
monitor being viewed. When the head restraint

Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your vehicle
was designed and tested with top-quality GM brake parts.
When you replace parts of your braking system — for
example, when your brake linings wear down and you
need new ones put in — be sure you get new approved
GM replacement parts. If you do not, your brakes may no
longer work properly. For example, if someone puts in
brake linings that are wrong for your vehicle, the balance
between your front and rear brakes can change — for the
worse. The braking performance you have come to
expect can change in many other ways if someone puts
in the wrong replacement brake parts.
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. See
Engine Compartment Overview on page 5-12for
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 5-39for tips on working around a battery
without getting hurt.
