Audio Steering Wheel Controls
If your vehicle has this feature, some audio functions
can be adjusted at the steering wheel. They include
the following:
wSEEKx:Press the up or the down arrow to go to
the next or to the previous radio station and stay
there. The radio will only seek stations with a strong
signal that are in the selected band.
When a cassette tape or CD is playing, press the up
arrow to go to the next selection.
AM/FM:Press this button to switch between FM1, FM2,
or AM. The selected band will appear on the display.SCAN:Press this button to scan the radio preset
stations. The radio will go to the rst preset station
stored on the pushbuttons, play for a few seconds,

Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise.
FM
FM stereo will give you the best sound, but FM signals
will reach only about 10 to 40 miles (16 to 65 km).
Tall buildings or hills can interfere with FM signals,
causing the sound to come and go.
3-72

Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes, or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight, and
extreme heat. If they are not, they may not operate
properly or may cause failure of the tape player.
The tape player should be cleaned regularly after every
50 hours of use. The radio may display CLN to
indicate that the tape player has been used for 50 hours
without resetting the tape clean timer. If CLN appears
on the display, the cassette tape player needs to
be cleaned. It will still play tapes, but it should be
cleaned as soon as possible to prevent damage to the
tapes and player. If there is a reduction in sound
quality, try a known good cassette to see if the tape or
the tape player is at fault. If this other cassette has
no improvement in sound quality, clean the tape player.
For best results, use a scrubbing action, non-abrasive
cleaning cassette with pads which scrub the tape
head as the hubs of the cleaner cassette turn. The
recommended cleaning cassette is available through
your dealer.The cut tape detection feature of the cassette
tape player may identify the cleaning cassette as a
damaged tape, in error. If the cleaning cassette ejects,
insert the cassette at least three times to ensure
thorough cleaning.
A non-scrubbing action, wet-type cleaner which uses a
cassette with a fabric belt to clean the tape head
can be used. 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 the player is cleaned, press and hold the EJECT
button for ve seconds to reset the CLN 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 the tape player
is serviced.

Engine Oil Life System
When to Change Engine Oil (Vehicles
With the GM Oil Life System)
If so equipped, your vehicle has a computer system that
lets you know when to change the engine oil and
lter. This is based on engine revolutions and engine
temperature, and not on mileage. Based on driving
conditions, the mileage at which an oil change will be
indicated can vary considerably. For the oil life system to
work properly, you must reset the system every time
the oil is changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. A CHANGE ENGINE OIL SOON message
will come on. Change your oil as soon as possible within
the next two times you stop for fuel. It is possible that,
if you are driving under the best conditions, the oil
life system may not indicate that an oil change is
necessary for over a year. However, your engine oil and
lter must be changed at least once a year and at
this time the system must be reset. Your dealer has
GM-trained service people who will perform this
work using genuine GM parts and reset the system. It is
also important to check your oil regularly and keep it
at the proper level.If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed.How to Reset the Oil Life System
The GM Oil Life System calculates when to change
your engine oil and lter based on vehicle use. Anytime
your oil is changed, reset the system so it can
calculate when the next oil change is required. If a
situation occurs where you change your oil prior to a
CHANGE ENGINE OIL SOON message being
turned on, reset the system.
Always reset the engine oil life to 100% after every oil
change. It will not reset itself. To reset the Oil Life
System, do the following:
1. Display OIL LIFE INDEX on the DIC.
2. Press and hold the DIC RESET button for
more than ve seconds. The oil life will change
to 100%.
3. Turn the key to OFF.
If the CHANGE ENGINE OIL SOON message comes
back on when you start your vehicle, the engine oil
life system has not reset. Repeat the procedure.

Adding Washer Fluid
If your vehicle has the Driver Information Center (DIC),
a WINDSHIELD WASHER FLUID LOW message
will be displayed when the windshield washer uid
reservoir is low. SeeDIC Warnings and Messages on
page 3-49for more information.
Open the cap with the
washer symbol on it. Add
washer uid until the
tank is full. SeeEngine
Compartment Overview
on page 5-12for
reservoir location.Notice:When using concentrated washer uid,
follow the manufacturer’s instructions for
adding water.
Do not mix water with ready-to-use washer uid.
Water can cause the solution to freeze and
damage your washer uid tank and other parts
of the washer system. Also, water does not
clean as well as washer uid.
Fill your washer uid tank only three-quarters
full when it is very cold. This allows for
expansion if freezing occurs, which could
damage the tank if it is completely full.
Do not use engine coolant (antifreeze) in your
windshield washer. It can damage your washer
system and paint.

The check tire pressure system detects differences in
tire rotation speeds that are caused by changes in
tire pressure. The system can alert you about a
low tire — but it does not replace normal tire
maintenance. SeeTires on page 5-58.
When the TIRE PRESSURE LOW message appears on
the Driver Information Center, you should stop as
soon as you can and check all your tires for damage. If
a tire is at, seeIf a Tire Goes Flat on page 5-73.
Also check the tire pressure in all four tires as soon as
you can. SeeInation - Tire Pressure on page 5-64.
Any time you adjust a tire’s pressure or have one
or more tires repaired or replaced, you will need to reset
(calibrate) the check tire pressure system. You will
also need to reset the system whenever you rotate the
tires, buy new tires and install or remove the compact
spare tire.
Do not reset the check tire pressure system without rst
correcting the cause of the problem and checking
and adjusting the pressure in all four tires. If you reset
the system when the tire pressures are incorrect,
the check tire pressure system will not work properly
and may not alert you when a tire is low or high.To reset (calibrate) the system:
1. Turn the ignition switch to RUN.
2. Press the GAGE INFO button on the DIC until TIRE
PRESSURE appears on the display.
3. Press and hold the DIC RESET button for about
ve seconds. After ve seconds, the display will
show TIRE PRESSURE RESET. If TIRE
PRESSURE RESET does not appear on the
display after about ve seconds, see your dealer for
service. After you release the DIC RESET button,
TIRE PRESSURE NORMAL will appear on
the display.
The system completes the calibration process during
driving. Calibration time can take 45 to 90 minutes,
depending on your driving habits. After the system
has been calibrated, the system will alert the driver
that a tire is low, up to a maximum speed of
65 mph (105 km/h).
