2005 CHEVROLET IMPALA Owners Manual

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 — 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.
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.

Power Door Locks
A power door lock switch
is located on each front
door above the armrest.
Press the top of the switch to unlock all doors, or press
the bottom part of the switch to lock all doors.
The rear doors do not have power door lock switches.
The manual lever on each rear door works only that
door’s lock.
If your vehicle has the optional content theft-deterrent
system and it is armed, the power door lock switches will
be disabled. You must use your remote keyless entry
transmitter or your key to unlock the doors when
the system is armed.
Programmable Automatic
Door Locks
Programmable automatic power door locks are a
standard feature that is intended to provide enhanced
security and convenience by automatically locking
and unlocking doors.
Programmable Modes
Mode 1:No automatic door lock or unlock.
Mode 2:Automatic all-door lock when the transaxle is
shifted out of PARK (P); no automatic door unlock.

PARK (P).
Mode 4:Automatic all-door lock when the transaxle is
shifted out of PARK (P); automatic all-door unlock
when the transaxle is shifted into PARK (P).
Your vehicle was originally programmed to Mode 4.
The mode may have been changed since then.
To determine the current mode, or to change the mode,
seeVehicle Personalization on page 2-38.
Disconnecting the battery for up to a year will not
change the programmed mode of the programmable

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.
Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot 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 Climate Control
System in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-26.

the inside.

especially with the windows closed in warm or
hot weather.

Power Windows
The power window
switches located on the
driver’s door armrest
control each of the

feature. This switch is labeled AUTO. Tap the rear of
the switch, and the driver’s window will open a
small amount. If the rear of the switch is fully pressed,
the window will go all the way down.To stop the window while it is lowering, press the front

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Content Theft-Deterrent
Your vehicle may have the optional content
theft-deterrent alarm system.
With this system, a light on the radio will ash.
This light reminds you to activate the theft-deterrent
system. Here’s how to do it:
1. Open the door.
2. Lock the door with the power door lock switch or
the remote keyless entry transmitter. The light on
the radio should come on and stay on. If you
are using the remote keyless entry transmitter,
the door does not need to be open.
3. Close all doors. The light on the radio will slowly
ash once the system is armed.Once armed, the alarm will go off if someone tries to
enter the vehicle (without using the remote keyless entry
transmitter or a key) or turns the ignition on with an
incorrect key. The horn will sound and the headlamps
and back-up lamps will ash for approximately
two minutes.
When the alarm is armed, the trunk may be opened
with the remote keyless entry transmitter. If you use the
key to open the trunk, the alarm will sound. The power
door lock switches are also disabled. You must use your
remote keyless entry transmitter or your key to unlock
the doors when the system is armed.
Arming with the Power Lock Switch
Your alarm system will arm when you use either power
lock switch to lock the doors while any door or the
trunk is open and the key is removed from the ignition.
The light on the radio ashes quickly to let you know
when the system is ready to arm with the power
door lock switches. The light on the radio will stop
ashing and stay on when you press the bottom of the
power lock switch, to let you know the system is
arming. After all doors and the trunk are closed and
locked, the light on the radio will ash slowly to let you
know the system is armed.
