GMC SIERRA CLASSIC 2007 Owners Manual

Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder
light and all your belts, buckles, latch plates,
retractors and anchorages are working properly.
Look for any other loose or damaged safety
belt system parts. If you see anything that might
keep a safety belt system from doing its job, have
it repaired. SeeCare of Safety Belts on page 592
for more information.
Torn or frayed safety belts may not protect you in
a crash. They can rip apart under impact forces.
If a belt is torn or frayed, get a new one right away.
Also look for any opened or broken airbag
covers, and have them repaired or replaced. The
airbag system does not need regular maintenance.Notice:If you damage the covering for the
driver’s or the right front passenger’s airbag,
the airbag may not work properly. You may
have to replace the airbag module in the
steering wheel or both the airbag module and
the instrument panel for the right front
passenger’s airbag. Do not open or break the
airbag coverings.

Replacing Restraint System Parts
After a Crash
{CAUTION:
A crash can damage the restraint systems
in your vehicle. A damaged restraint
system may not properly protect the
person using it, resulting in serious injury
or even death in a crash. To help make
sure your restraint systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as possible.If you have had a crash, do you need new belts or
LATCH system parts?
After a very minor collision, nothing may be
necessary. But if the belts were stretched, as they
would be if worn during a more severe crash,
then you need new parts.
If the LATCH system was being used during a
more severe crash, you may need new LATCH
system parts.
If belts are cut or damaged, replace them.
Collision damage also may mean you will need to
have LATCH system, safety belt or seat parts
repaired or replaced. New parts and repairs may
be necessary even if the belt or LATCH system
was not being used at the time of the collision.
If an airbag inates, you will need to replace airbag
system parts. See the part on the airbag system
earlier in this section.

Keys
{CAUTION:
Leaving children in a vehicle with the
ignition key is dangerous for many
reasons. They could operate the power
windows or other controls or even make
the vehicle move. The children or others
could be badly injured or even killed.
Do not leave the keys in a vehicle with
children.
115

Your vehicle has
one double-sided key
for the ignition, all
door locks, and the
spare tire hoist lock if
your vehicle has one.
If you ever lose your keys, your dealer will be able
to assist you with obtaining replacements.
Notice:If you ever lock your keys in your
vehicle, you may have to damage the vehicle
to get in. Be sure you have spare keys.
If you ever do get locked out of your vehicle, call
the GM Roadside Assistance Center. See
Roadside Assistance Program on page 644.Remote Keyless Entry System
If the vehicle has a Remote Keyless Entry (RKE)
system operates on a radio frequency subject
to Federal Communications Commission (FCC)
Rules and with Industry Canada.
This device complies with Part 15 of the FCC
Rules. Operation is subject to the following
two conditions:
1. This device may not cause interference, and
2. This device must accept any interference
received, including interference that may
cause undesired operation of the device.
This device complies with RSS-210 of Industry
Canada. Operation is subject to the following
two conditions:
1. This device may not cause interference, and
2. This device must accept any interference
received, including interference that may
cause undesired operation of the device.
Changes or modications to this system by other
than an authorized service facility could void
authorization to use this equipment.
116

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.
117

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 282for 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 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.
118

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.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers, especially children, can
easily open the doors and fall out of a
moving vehicle. When a door is
locked, the handle will not open it.
You increase the chance of being
thrown out of the vehicle in a crash if
the doors are not locked. So, wear
safety belts properly and lock the
doors whenever you drive.
CAUTION: (Continued)
CAUTION: (Continued)

Young children who get into unlocked
vehicles may be unable to get out.
A child can be overcome by extreme
heat and can suffer permanent injuries
or even death from heat stroke.
Always lock your vehicle whenever
you leave it.
Outsiders can easily enter through an
unlocked door when you slow down
or stop your vehicle. Locking your
doors can help prevent this from
happening.
There are several ways to lock and unlock your
vehicle.
