CHEVROLET IMPALA 2003 8.G Manual PDF

One key is used for the
ignition, the driver's door
and all other locks.
If you need a new key, contact your dealer for
assistance. In an emergency, contact Chevrolet
Roadside Assistance. See
Roadside Assistance
Program on page 7-5for more information.
Notice:Your vehicle has a number of features
that can help prevent theft. You can have a lot of
trouble getting into your vehicle if you ever lock
your keys inside. You may even have to damage
your vehicle to get in. So be sure you have
spare keys.
If your vehicle is equipped with the OnStar
žsystem,
with an active subscription and you lock your keys inside
the vehicle, OnStar
žmay be able to send a command
to unlock your vehicle. SeeOnStaržSystem on
page 2-37for more information.

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 or
resynchronization is necessary. See ªBattery
Replacementº and ªResynchronizationº under
Remote Keyless Entry System Operation on
page 2-4.
·If you are still having trouble, see your dealer or a
quali®ed technician for service.
Remote Keyless Entry System
Operation
Using the remote keyless
entry transmitter, you can
lock and unlock your
doors or release your trunk
from about 3 feet (1 m)
up to 30 feet (9 m) away.
LOCK:Press the LOCK button to lock all the doors.

L(Remote Alarm):Press this button to activate an
alarm. The ignition must be in OFF or ACC for the
remote alarm to work. When you press the remote
button, the headlamps will ¯ash, the horn will sound
repeatedly and your interior lamps will turn on attracting
attention if you need it. The alarm will continue until
one of the following occurs:
·The remote alarm button is pressed a second time,
·the vehicle's ignition is turned to ON or
·an alarm period of 110 seconds has elapsed.
V(Trunk Release):Press the button to release
the trunk.
Operating the remote keyless entry transmitter may
interact with the content theft-deterrent system, if your
vehicle has this option. See
Content Theft-Deterrent
on page 2-16.
Transmitter Veri®cation
This feature provides feedback that a command has
been received by the vehicle. The headlamps and
back-up lamps will ¯ash on every lock and on the ®rst
unlock command. The horn will also sound once
for every lock and twice for the ®rst unlock command.
Silent operation and other options may be selected
for this feature. See
Vehicle Personalization on
page 2-45.
If your vehicle has the optional content theft-deterrent
system, the ®rst time the remote unlock is received,
three ¯ashes from the headlamps will be seen and three
chirps will be heard to indicate an alarm condition has
occurred since last arming. See
Content Theft-Deterrent
on page 2-16.
2-5

Illumination on Remote Activation
The interior lamps will come on when either the
UNLOCK, the trunk release or the remote alarm button
is pressed. The interior lamps will remain on for
40 seconds or until the ignition is turned to ON or LOCK
is pressed. Locking the doors with the power door
locks will also cause the lamps to turn off. If a door is
opened during the 40 second period, the interior
lamps will remain on while the door is open.
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.
If you prefer, you can complete this procedure yourself.
See
Vehicle Personalization on page 2-45for more
information.
2-6

Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about three 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.
To replace the battery do the following:
1. Insert a ¯at object like a coin into the slot on the
back of the transmitter. Gently pry apart the front
and back.
2. Gently pry the battery out of the transmitter. Do not
use a metal object.
3. Put the new battery into the transmitter as shown
on the transmitter. Use type CR2032 battery or
equivalent.
4. Put the two halves back together. Make sure the
halves are together tightly so water won't get in.
5. Resynchronize and then test the transmitter.
Resynchronization
After you have changed the battery in your transmitter,
you will need to resynchronize the transmitter. To
do this, press the LOCK and UNLOCK buttons on the
transmitter at the same time and hold for about
seven seconds or until one horn chirp is heard.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
·Passengers Ð especially children Ð can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle won't open it. You increase the
chance of being thrown out of the vehicle
in a crash if the doors aren't locked. So,
wear safety belts properly and lock the
doors whenever you drive.
·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.
From the outside, use your key or remote keyless
entry transmitter. From the inside, use the manual or
power door locks.
To unlock the driver's side door from the outside with
the key, insert the key and turn it toward the front of the
vehicle. To lock the driver's side door from the outside
with your key, insert the key and turn it toward the
rear of the vehicle.
To lock the door from the inside, push the manual lock
lever forward. To unlock the door, pull the lever
rearward.

Lockout Protection
To protect you from locking your key in the vehicle, this
feature stops the power door locks from locking while
the key is in the ignition and a door is open.
If a power lock switch is pressed while a door is open
and the key is in the ignition, all of the doors will
lock and then the driver's door will unlock. A chime will
sound continuously until all doors are closed.
Leaving Your Vehicle
If you are leaving the vehicle, take your keys, open your
door and set the locks from inside. Then get out and
close the door.
Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can't see or smell
CO. It can cause unconsciousness and even
death. If you must drive with the trunk lid open
or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
·Make sure all other windows are shut.
·Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See ªClimate Control
Systemº in the Index.
