key battery GMC SIERRA CLASSIC 2007 Owners Manual

{CAUTION:
For up to 10 seconds after the ignition key
is turned off and the battery is
disconnected, an airbag can still inate
during improper service. You can be
injured if you are close to an airbag when
it inates. Avoid yellow connectors. They
are probably part of the airbag system. Be
sure to follow proper service procedures,
and make sure the person performing
work for you is qualied to do so.
The airbag system does not need regular
maintenance.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front of
the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change your
vehicle’s frame, bumper system, height,
front end or side sheet metal, they may keep
the airbag system from working properly.
Also, the airbag system may not work properly
if you relocate any of the airbag sensors. If
you have any questions about this, you should
contact Customer Assistance before you
modify your vehicle. The phone numbers and
addresses for Customer Assistance are in
Step Two of the Customer Satisfaction
Procedure in this manual. SeeCustomer
Satisfaction Procedure on page 638.

At times you may notice a decrease in 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 or
resynchronization is necessary. See “Battery
Replacement” and “Resynchronization”
underRemote Keyless Entry System
Operation on page 117.
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 (RKE) 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 within
three seconds will cause
the remaining doors
to unlock.
You can choose different feedback options for
each press of the unlock button. See “Lock
Feedback” and “Unlock Feedback” underDIC
Vehicle Customization on page 282for more
information.

To replace the battery in the RKE transmitter, do
the following:
1. Insert a thin object, such as a coin, in the slot
between the covers of the transmitter housing
near the key ring hole. Remove the bottom
by twisting the coin.
2. Remove and replace the battery with a
three-volt CR2032 or equivalent battery,
positive (+) side up.
3. Align the covers and snap them together.
4. Resynchronize the transmitter. See
“Resynchronization” following this information.
5. Check the operation of the transmitter.Resynchronization
Resynchronization may be necessary due to the
security method used by this system. The
transmitter does not send the same signal twice to
the receiver. The receiver will not respond to a
signal that has been sent previously. This prevents
anyone from recording and playing back the
signal from the transmitter.
To resynchronize your transmitter, stand close to
your vehicle and press and hold the lock and
unlock buttons on the transmitter at the same time
for 15 seconds. The door locks should cycle to
conrm synchronization. If the locks do not cycle,
see your dealer for service.

This message reminds you to activate the
theft-deterrent system. Here is how to do it:
1. Open the door.
2. Lock the door with the Remote Keyless Entry
(RKE) transmitter. The security light should
come on and ash. The door does not need to
be open.
If the delayed locking feature is active, the
alarm will not be activated until all doors are
closed and the security light goes off.
3. Close all doors. The security light will stop
ashing and go off after approximately
30 seconds. The content theft deterrent alarm
is not armed until the security light goes off.
If a door is opened without using the RKE
transmitter, the alarm will go off. Your vehicle’s
headlamps will ash and the horn will sound
for about two minutes, then will turn off to save
the battery power.The theft-deterrent system will not activate if you
lock the doors with a key, the manual door lock, or
the power door lock switch. It activates only if you
use the RKE transmitter. You should also
remember that you can start your vehicle with the
correct ignition key if the alarm has been set off.
Here is how to avoid setting off the alarm by
accident:
If you do not want to activate the
theft-deterrent system, the vehicle should be
locked with the door key after the doors
are closed.
Always unlock a door with the remote keyless
entry transmitter. Unlocking a door any other
way will set off the alarm if the system
has been armed.
If you set off the alarm by accident, turn off the
alarm by pressing unlock on the remote keyless
entry transmitter or by placing the key in the
ignition and turning it to START.

C (RUN):This is the position for driving.
The battery could be drained if you leave the key
in the ACCESSORY or RUN 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.
D (START):This position starts your engine.
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 transaxle. Also, always remember
to lock the doors.
The battery could be drained if you leave the key

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 your engine gets warm. 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.
Your vehicle has a Computer-Controlled
Cranking System. This feature assists in
starting the engine and protects the electrical
system. If the ignition key is turned to the
START, and then released when the engine
begins cranking, the engine will continue
cranking until the vehicle starts or until
it exceeds the maximum cranking time allowed,
approximately 15 seconds to prevent cranking
motor damage. To prevent gear damage,
this system also prevents cranking if the
engine is already running. The engine cranking
can be stopped by turning the ignition switch
to the ACCESSORY or LOCK.Notice:Holding your key in START for longer
than 15 seconds at a time will disengage
the starter motor, cause your battery to be
drained much sooner, and add excessive heat
that can damage your starter motor. Try not
to hold the key in START for longer than
15 seconds and wait about 15 seconds
between each try to help avoid draining your
battery or damaging your starter.
2. If it does not start within 10 seconds, push the
accelerator pedal all the way to the oor,
while you hold the ignition key in START.
When the engine starts, let go of the key and
let up on the accelerator pedal. Wait about
15 seconds between each try.

Battery Warning Light
If this light comes on
when the engine is
running, there could be
a problem with the
charging system.
The battery display will also stay on while the key
is in RUN until the engine is started.
If the light stays on after starting the engine it
could indicate a problem with the generator drive
belt, or some other charging system problem.
Have it checked right away. Driving while this light
is on could drain the battery.
If you must drive a short distance with this light
on, it helps to turn off all your accessories, such as
the radio and the air conditioner.
Voltmeter Gage
When the engine is not
running, but the ignition
is in RUN, this gage
shows your battery’s
state of charge in
DC volts.
While the engine is running, this gage shows the
condition of the charging system. The gage
may transition from a higher to lower or a lower to
higher reading. This is normal. Readings
between the low and high warning zones indicate
the normal operating range. The voltmeter
gage may also read lower when in fuel economy
mode. This is normal.
Readings in the low warning zone may occur
when a large number of electrical accessories are
operating in the vehicle and the engine is left at
an idle for an extended period.
