2004 Chevrolet Classic Owner ManualM

{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’t 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.
In many crashes severe enough to inflate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.
•Air bags are designed to inflate only once. After an
air bag inflates, you’ll need some new parts for your
air bag system. If you don’t get them, the air bag
system won’t be there to help protect you in another
crash. A new system will include air bag modules
and possibly other parts. The service manual for your
vehicle covers the need to replace other parts.
•Your vehicle is equipped with a crash sensing and
diagnostic module, which records information about
the air bag system. The module records information
about the readiness of the system, when the system
commands air bag inflation and driver’s safety belt
usage at deployment.
•Let only qualified technicians work on your air bag
system. Improper service can mean that your air bag
system won’t work properly. See your dealer for
service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s air bag, the bag
may not work properly. You may have to replace the
air bag module in the steering wheel or both the
air bag module and the instrument panel for
the right front passenger’s air bag. Do not open or
break the air bag coverings.

Servicing Your Air Bag-Equipped
Vehicle
Air bags affect how your vehicle should be serviced.
There are air bag system parts in several places around
your vehicle. You don’t want the system to inflate
while someone is working on your vehicle. Your dealer
and the service manual have information about
servicing your vehicle and the air bag system. To
purchase a service manual, seeService Publications
Ordering Information on page 7-11.
{CAUTION:
For up to 10 minutes after the ignition key is
turned off and the battery is disconnected, an
air bag can still inate during improper
service. You can be injured if you are close to
an air bag when it inates. Avoid yellow
connectors. They are probably part of the air
bag system. Be sure to follow proper service
procedures, and make sure the person
performing work for you is qualied to do so.
Air bag systems do not need regular maintenance.
Restraint System Check
Checking Your 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.
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 air bag covers, and
have them repaired or replaced. The air bag system
does not need regular maintenance.
1-62

One key is used for the
ignition and all other locks.
When a new vehicle is delivered to the dealer, the key
has a key tag. This tag has a bar-coded key code
that tells your dealer how to make extra keys. This tag
may be removed and kept by your dealer. If it hasn’t
been removed, keep the tag in a safe place. If you lose
your key, your dealer can easily make another one
by using the key code. SeeRoadside Assistance
Program on page 7-6for more information.
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.Remote Keyless Entry System
If equipped, the keyless entry system operates on a
radio frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.

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 is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-4.
•If you are still having trouble, see your dealer or a
qualified technician for service.
Remote Keyless Entry System
Operation
The following functions are
available with the keyless
entry system:
Q(Lock):Press the lock button to lock all of the
doors. The interior lamps will turn off after all of
the doors are closed.
W(Unlock):Press the unlock button once to unlock
the driver’s door. Press the button again within five
seconds for all remaining doors to unlock. The interior
lamps will stay on for 10 seconds or until the ignition
is turned on.
2-4

Ignition Positions
With the key in the ignition switch, you can turn it to four
different positions.
Notice:If your key seems stuck in OFF and you
can’t turn it, be sure you are using the correct key;
if so, is it all the way in? Turn the key only with
your hand. Using a tool to force it could break the
key or the ignition switch. If none of this works, then
your vehicle needs service.A (OFF):This is the only position from which you can
remove the key. It also locks your ignition and transaxle.
A warning chime will sound if you open the driver’s
door when the ignition is off and the key is in the ignition.
B (ACCESSORY):This position lets you use things
like the radio and windshield wipers when the engine is
not running. To use ACCESSORY, turn the key
clockwise to the first position.
Use this position if your vehicle must be pushed or
towed, but never try to push-start your vehicle.
SeeRecreational Vehicle Towing on page 4-30.
C (ON):This position unlocks the ignition. It is also the
position to where the key returns after you start the
engine and release the switch. The switch will stay in
this position when the engine is running. But even when
the engine is not running, you can use ON to operate
your electrical accessories, and to display some
instrument panel warning lights.
D (START):This position starts the engine. When the
engine starts, release the key. The ignition switch
will return to ON for normal driving.
2-17

You’ll shift down to the next gear and have more power.
Notice:Driving your vehicle if you notice that it
is moving slowly or not shifting gears as you
increase speed may damage the transaxle. Have
your vehicle serviced right away. You can drive in
SECOND (2) when you are driving less than 35 mph
(55 km/h) and AUTOMATIC OVERDRIVE (D) for
higher speeds until then.
THIRD (3):This position is also used for normal driving.
However, it offers more power and lower fuel economy
than AUTOMATIC OVERDRIVE (D). Here are some
times you might choose THIRD (3) instead of
AUTOMATIC OVERDRIVE (D):
•When driving on hilly, winding roads.
•When towing a trailer, so there is less shifting
between gears.
•When going down a steep hill.SECOND (2):This position gives you more power but
lower fuel economy than THIRD (3). You can use
SECOND (2) on hills. It can help control your speed as
you go down steep mountain roads, but then you
would also want to use your brakes off and on.
Notice:Driving in SECOND (2) for more than
25 miles (40 km) or at speeds over 55 mph (90 km/h)
may damage the transaxle. Also, shifting into
SECOND (2) at speeds above 65 mph (105 km/h) can
cause damage. Drive in THIRD (3) or AUTOMATIC
OVERDRIVE (D) instead of SECOND (2).
FIRST (1):This position gives you even more power
but lower fuel economy than SECOND (2). You can use
it on very steep hills, or in deep snow or mud. If the
shift lever is put in FIRST (1), the transaxle won’t shift
into first gear until the vehicle is going slow enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transaxle. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
