2002 BUICK LESABRE service indicator

2-23
(B) LOCK: This is the only position in which you
can remove the key. This position locks your ignition,
steering wheel and transaxle. It's a theft
-deterrent feature.
NOTICE:
If your key seems stuck in LOCK and you can't
turn it, be sure you are using the correct key;
if so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. 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.
(C) OFF: This position lets you turn off the engine but
still turn the steering wheel. It doesn't lock the steering
wheel like LOCK and it doesn't send any electrical
power to the accessories. The instrument panel cluster
will remain powered in LOCK to illuminate the gear
shift indicator. The cluster will also activate the parking
brake light when the parking brake is set. Use UNLOCK
if you must have your vehicle in motion while the
engine is not running.(D) RUN: This is the position the switch returns to after
you start your engine and release the switch. This is also
the position for normal driving. Even when the engine is
not running, you can use RUN to operate your power
accessories and to display some instrument panel
warning lights.
(E) START: This position starts your engine. When
the engine starts, release the key. The ignition switch
will return to RUN for normal driving.
Key Reminder Warning
If you leave your key in OFF, you will hear a warning
chime when you open the driver's door.
Always leave your key in LOCK. If you leave it in any
other position, you will drain your battery power.
Retained Accessory Power (RAP)
After you turn the ignition off and remove the key,
you will still have power to such accessories as the
power windows, audio steering wheel controls
(if equipped), clock, sunroof (option) and the radio
for up to 10 minutes. The instrument panel cluster
lights will stay on for a few seconds, then will go out.
Once you open a door, the power will shut off.

2-76 Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature. If the
pointer moves into the
shaded area, the engine
is too hot.
A temperature indicator light will turn on and a chime
will sound.
If you have been operating your vehicle under normal
driving conditions, and the temperature indicator light
comes on, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
Malfunction Indicator Lamp
(Service Engine Soon Light)
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (On
-Board
Diagnostics
-Second Generation) and is intended
to assure that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment. The SERVICE ENGINE SOON light
comes on to indicate that there is a problem and service
is required. Malfunctions often will be indicated by the
system before any problem is apparent. This may
prevent more serious damage to your vehicle. This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.

2-81 Cruise Light
The CRUISE light comes
on when you set the
vehicle's cruise control.
See ªCruise Controlº
in the Index.
Fuel Gage
United States CanadaThe fuel gage shows about how much fuel is in your
tank. It works only when the ignition is on. When the
indicator moves to the edge of the low fuel warning
band, the low fuel warning light will come on and a
chime will sound. You still have a little fuel left, but
you need to get more fuel right away.
Here are some things that some owners ask about.
None of these show a problem with your fuel gage:

At the service station, the gas pump shuts off before
the gage reads full.

It takes more (or less) fuel to fill up than the gage
indicated. For example, the gage may have indicated
half full, but it took more (or less) than half the
tank's capacity to fill it.

The gage moves up a little when you turn a corner,
speed up or make a hard stop.

The gage doesn't go back to empty when you turn
off the ignition.

3-43
When cleaning the cassette tape player with the
recommended non
-abrasive cleaning cassette, it is
possible that the cassette may eject, because the cut tape
detection feature on your radio may recognize it as a
broken tape. If the cleaning cassette ejects, insert the
cassette at least three times to ensure thorough cleaning.
You may also choose a non
-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt to clean
the tape head. This type of cleaning cassette will not
eject on its own. A non
-scrubbing action cleaner may
not clean as thoroughly as the scrubbing type cleaner.
The use of a non
-scrubbing action, dry-type cleaning
cassette is not recommended.
After you clean the player, press and hold the eject
button for five seconds to reset the CLEAN PLAYER
indicator. The radio will display
--- to show the
indicator was reset.
Cassettes are subject to wear and the sound quality
may degrade over time. Always make sure the cassette
tape is in good condition before you have your tape
player serviced.
Care of Your Compact Discs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc is soiled, dampen a
clean, soft cloth in a mild, neutral detergent solution and
clean it, wiping from the center to the edge.
Be sure never to touch the signal surface when handling
discs. Pick up discs by grasping the outer edges or the
edge of the hole and the outer edge.
Care of Your Compact Disc Player
The use of CD lens cleaner discs is not advised, due to
the risk of contaminating the lens of the CD optics with
lubricants internal to the CD mechanism.

6-5 Additives
Some gasolines that are not reformulated for low
emissions may contain an octane
-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask the attendant where you buy gasoline
whether the fuel contains MMT. General Motors does
not recommend the use of such gasolines. Fuels
containing MMT can reduce the life of spark plugs and
the performance of the emission control system may be
affected. The malfunction indicator lamp may turn on.
If this occurs, return to your authorized GM dealer
for service.
To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent engine and fuel system deposits from forming,
allowing your emission control system to work properly.
You should not have to add anything to your fuel.
Gasolines containing oxygenates, such as ethers and
ethanol, and reformulated gasolines may be available
in your area to contribute to clean air. General Motors
recommends that you use these gasolines, particularly
if they comply with the specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don't use fuel containing
methanol. It can corrode metal parts in your
fuel system and also damage plastic and rubber
parts. That damage wouldn't be covered under
your warranty.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard
to find. Never use leaded gasoline or any other fuel not
recommended in the previous text on fuel. Costly repairs
caused by use of improper fuel wouldn't be covered by
your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in
the country where you'll be driving.

6-31 Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built
-in wear indicators that make
a high
-pitched warning sound when the brake pads
are worn and new pads are needed. The sound may
come and go or be heard all the time your vehicle is
moving (except when you are pushing on the brake
pedal firmly).
CAUTION:
The brake wear warning sound means that soon
your brakes won't work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
Some driving conditions or climates may cause a
brake squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
your brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly tighten wheel nuts in the
proper sequence to GM torque specifications.
Brake linings should always be replaced as complete
axle sets.
See ªBrake System Inspectionº in Section 7 of this
manual under Part C ªPeriodic Maintenance Inspections.º
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.
