Keyless Entry System
If your vehicle has this option, you can lock and unlock
your doors from about
3 feet (1 m) up to 30 feet (9 m)
away using the remote keyless entry transmitter supplied
with your vehicle.
Your Keyless Entry System operates on a radio frequency
subject to Federal Communications Commission (FCC)
Rules and with Industry and Science 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 harmful interference, and
(2) this device must accept any interference received,
including interference that may cause undesired operation. This device
complies with
RSS-210 of Industry and
Science 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 modifications to this
system by other than an
authorized service facility could void authorization to
use this equipment.
This system has a range of about
3 feet (1 m) up to
30 feet (9 m). 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:
0 Check to determine if battery replacement or
transmitter resynchronization is necessary. See the
instructions that follow.
0 Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.
0 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.
0 If you’re still having trouble, see your GM dealer or
a qualified technician for service.

Operation
To unlock the driver’s door, press the UNLOCK button.
If
you press this button again within five seconds, all
the doors will unlock. Press the
REAR button twice
to unlock the rear door only. When the UNLOCK or
REAR button is pressed, the interior dome lamps are
turned on for
40 seconds or until the ignition switch
is activated. Press
LOCK to lock all the doors.
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 only two transmitters
matched to it.
Battery Replacement
Under normal use, the battery in your key remote
keyless entry transmitter should last about
two years.
You can tell the battery is weak if
the transmitter won’t
work at the normal range in any location.
If you have to
get close to your vehicle before
the transmitter works,
it’s 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.

Battery
Every new vehicle has a Delco Freedom@ battery. You
never have to add water to one of these. When it’s time
for
a new battery, we recommend a Delco Freedom
battery. Get one that has the replacement number shown
on the original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days or more,
take off the black, negative (-) cable from the battery. This
will help keep your battery from running down. Contact
your dealer
to learn how to prepare your vehicle
for longer storage periods.
Also, for your audio system, see “Theft-Deterrent
Feature” in the Index.
Bulb Replacement
Before you replace any bulbs, be sure that all the lamps
are off and the engine isn’t running. See “Replacement
Bulbs”
in the index for the proper types of bulbs to use.
Halogen Bulbs
A CAUTION:
Batteries have acid that can Durn you and gas
that can explode. You can be badly hurt
if you
aren’t careful. See “Jump Starting” in the Index
for tips
on working around a battery without
getting hurt.
A CAUTION:
Halogen bulbs have pressurized gas inside and
can burst if you drop or scratch the bulb. You
or
others could be injured. Be sure to read and
follow the instructions
on the bulb package.
