2004 Chevrolet Impala Owner ManualM

Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here’s how to wear it
properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see
how, see “Seats” in the Index.3. Pick up the latch plate and pull the belt across you.
Don’t let it get twisted.
The shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the belt
go back slightly to unlock it. Then pull the belt
across you more slowly.
4. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
If the belt isn’t long enough, seeSafety Belt
Extender on page 1-30.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.

If your vehicle has one, the driver’s side impact air bag is
in the side of the driver’s seatback closest to the door.
{CAUTION:
If something is between an occupant and an
air bag, the bag might not inate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inating air bag must be kept clear. Do not put
anything between an occupant and an air bag,
and do not attach or put anything on the
steering wheel hub or on or near any other air
bag covering. Do not let seat covers block the
ination path of a side impact air bag.
1-55

What Will You See After an Air Bag
Inates?
After the air bag inates, it quickly deates, so quickly that
some people may not even realize the air bag inated.
Some components of the air bag module will be hot for a
short time. These components include the steering wheel
hub for the driver’s frontal air bag and the instrument
panel for the right front passenger’s frontal air bag. For
vehicle’s with a driver’s side impact air bag, the side of
the seatback closest to the driver’s door will be hot. The
parts of the bag that come into contact with you may be
warm, but not too hot to touch. There will be some smoke
and dust coming from the vents in the deated air bags.
Air bag ination doesn’t prevent the driver from seeing or
being able to steer the vehicle, nor does it stop people
from leaving the vehicle.
{CAUTION:
When an air bag inates, there is dust in the
air. This dust could cause breathing problems
for people with a history of asthma or other
breathing trouble. To avoid this, everyone in
the vehicle should get out as soon as it is safe
to do so. If you have breathing problems but
can not get out of the vehicle after an air bag
inates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an air bag deployment, you
should seek medical attention.
Your vehicle has a feature that will automatically unlock
the doors and turn the interior lamps on when the air
bags inate (if battery power is available). You can lock
the doors again and turn the interior lamps off by
using the door lock and interior lamp controls.

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,

2-3

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 “Battery
Replacement” and “Resynchronization” under
Remote Keyless Entry System Operation on
page 2-4.
If you are still having trouble, see your dealer
or a qualied 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.
UNLOCK:Press the UNLOCK button once to unlock
the driver’s door and turn on the interior lamps. See
“Illumination on Remote Activation” later in this section for
more details. Pause for about one second, then press
UNLOCK again to unlock the passenger door.
2-4

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.
SeeVehicle Personalization on page 2-44for more
information.
