2004 CHEVROLET IMPALA Owners Manual

Passenger Compartment Air Filter
Your vehicle may be equipped with a passenger
compartment particulate air lter. It is located
underneath the hood just below the windshield wiper
arm on the passenger’s side of the vehicle, underneath
the air inlet grille.
The lter traps most of the pollen from air entering the
Climate Control System. Like your engine’s air
cleaner/lter, it may need to be changed periodically to
insure system performance. For information on how
often to change the passenger compartment air
lter, seeScheduled Maintenance on page 6-4.
To change the passenger compartment air lter, use the
following steps:
1. Turn off the ignition when the windshield wipers are
in the up position.
2. Raise the vehicle hood.
3. Disconnect the windshield washer pump hose from
the fender rail and air inlet grille.
4. Peel back the hood weatherstrip from the
passenger’s side of the vehicle halfway to center.5. Remove the air inlet grille retainers.
6. Remove the air inlet grille.
7. Remove the air deector grille in the compartment.
8. Remove the old passenger compartment air
lter.
9. Reverse the steps to install the new air lter.
For the type of lter to use, seeNormal Maintenance
Replacement Parts on page 6-13.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something
is wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention
to your warning lights and gages could also save
you or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you
will see in the details on the next few pages, some
warning lights come on briey when you start the engine
just to let you know they’re working. If you are familiar
with this section, you should not be alarmed when
this happens.Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there’s a problem with your vehicle.
When one of the warning lights comes on and stays
on when you are driving, or when one of the gages
shows there may be a problem, check the section that
tells you what to do about it. Please follow this
manual’s advice. Waiting to do repairs can be
costly – and even dangerous. So please get to know
your warning lights and gages. They’re a big help.
Your vehicle may also have a Driver Information
Center (DIC) that works along with the warning lights
and gages. SeeDriver Information Center (DIC)
on page 3-52.

Instrument Panel Cluster
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You’ll know how
fast you’re going, about how much fuel is in your tank and many other things you need to drive safely and
economically.

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your odometer shows how far your vehicle has
been driven in either miles (used in the United States)
or in kilometers (used in Canada).
Your vehicle has a tamper-resistant odometer. If you
see ERROR, you’ll know someone has probably
tampered with it and the numbers may not be accurate.
You may wonder what happens if your vehicle needs
a new odometer installed. If the new one can be set to
the mileage total of the old odometer, then that will
be done. But if it can’t, then it will be set at zero and a
label must be put on the driver’s door to show the
old mileage reading when the new odometer was
installed.
Trip Odometer
Your trip odometer tells how far you have driven since
you last reset it.
Your trip/select reset switch will go back and forth
between the odometer and the trip odometer if the
button is pressed and released within 1.5 seconds. If the
button is pressed and held for longer than 1.5 seconds
while in the trip odometer mode, it will be reset to
zero. If the button is pressed and held for longer than
1.5 seconds while in the odometer mode, it will have
no effect.
Your trip odometer will work no matter what position
your key is in, and even if the key isn’t in.

Tachometer
Your vehicle may have a
tachometer that displays
the engine speed in
thousands of revolutions
per minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your vehicle
could be damaged, and the damages would not
be covered by your warranty. Do not operate
the engine with the tachometer in the shaded
warning area.
Safety Belt Reminder Light
When the key is turned to ON, a chime will come on for
about several seconds to remind people to fasten
their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay on
for several seconds, then it
will ash for several more.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag’s electrical system for malfunctions.
The light tells you if there is an electrical problem.
The system check includes the air bag sensors, the air
bag modules, the wiring and the crash sensing and
diagnostic module. For more information on the air bag
system, seeAir Bag Systems on page 1-51.This light will come on
when you start your
vehicle, and it will ash for
a few seconds. Then
the light should go out.
This means the system
is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.
