The ENG button scrolls through the following functions:

Oil pressure, such as:
OIL PRESSURE 40 PSI or OIL PRESSURE
276 kPa

Battery voltage, such as:
BATTERY 13.8 VOLTS

Transaxle fluid life, such as:
TRANS FLUID LIFE 40%
This is an estimate of the transaxle fluid's remaining
useful life. It will show 100% when the system is
reset after a transaxle fluid change. It will alert you
to change your transaxle fluid on a schedule
consistent with your driving conditions.

Engine oil life, such as:
OIL LIFE 30%
This is an estimate of the oil's remaining useful life.
It will show 100% when the system is reset after an
oil change. It will alert you to change your oil on a
schedule consistent with your driving conditions.When the remaining oil life or transaxle fluid life is low,
the system will alert you with a message:
CHANGE OIL SOON or CHANGE TRNS
FLUID SOON
When the oil or transaxle fluid life is down to zero, you
will receive the message:
CHANGE OIL NOW or CHANGE TRNS
FLUID NOW
Always reset the OIL LIFE reminder after an oil change
or the TRNS FLUID LIFE reminder after a transaxle
fluid change. To reset the TRNS FLUID LIFE:
1. With the ignition on, press the ENG button so the
TRNS LIFE percentage is displayed.
2. Press RESET and hold for five seconds. The word
RESET will appear, then TRNS FLUID 100%.
To reset the Oil Life Monitor, see ªEngine Oil Life
Monitorº in the Index. Also, see ªEngine Oil, When to
Changeº in the Index.

Remember, you must reset the OIL LIFE or TRNS
FLUID yourself after each oil or transaxle fluid change.
It will not reset itself. Also, be careful not to reset the
OIL LIFE or TRNS FLUID accidentally at any time
other than when the oil or transaxle fluid has just been
changed. It can't be reset accurately until the next oil or
transaxle fluid change.
The DIC does not replace the need to maintain your
vehicle as recommended in the Maintenance Schedule in
this manual. Also, the oil change reminder will not
detect dusty conditions or engine malfunctions that may
affect the oil. If you drive in dusty areas, change your oil
after every 3,000 miles (5 000 km) or three months,
whichever occurs first, unless the DIC instructs you to
do so sooner. Also, the oil change reminder does not
measure how much oil you have in your engine. So, be
sure to check your oil level often. See ªEngine Oilº in
the Index.Check Oil Level Warning
When CHECK OIL LEVEL appears, it indicates that the
engine oil level is 1 to 1 1/2 quarts (0.9 L to 1.4 L) low.
The message will appear only if the engine is running
and it's been at least eight minutes since the engine was
last running. If the message appears, check the oil
dipstick level. If it reads low, your oil level should be
brought up to the proper level (see ªEngine Oilº in the
Index). After bringing the oil to the proper level, the
ignition must be off for eight minutes to allow the
majority of oil to drain into the oil pan.
Distance to Destination
This feature acts as a reverse trip odometer by counting
backward from an estimated distance which you enter
before starting your trip. It also uses that information to
determine the estimated time of arrival.
To set, press DEST, then RESET and enter a maximum
of four digits for the length of your trip. (Always use
whole miles or kilometers.) Then press ENTER. The
system will only accept the last four digits you enter as
your distance to destination.

In cold weather, the system will delay turning on the fan
to avoid blowing cold air. The length of the delay
depends on the engine coolant temperature and the
outside temperature. Turning the AUTO FAN knob will
override this delay by turning off the automatic fan
mode and changing the fan speed.
Your automatic electronic climate control system has
two sun sensors located on the top of the instrument
panel that detect direct sunlight. To keep you and your
passengers comfortable, the system may supply cooler
air to the side toward the sun. Be careful not to put
anything over these sun sensors. The automatic
electronic climate control system may not operate
correctly if these sensors are covered.To change the automatic electronic climate control
display from an English display to a metric display, push
the OFF button located in the Driver Information Center
(DIC) for two seconds. The display in the DIC will also
change from an English to a metric display. To return to
an English display, repeat the above procedure.
Manual Operation
You may override the automatic airflow distribution by
turning the AUTO
-PUSH knob. After you turn this
knob, the comfort setting will be displayed for five
seconds, then the outside temperature will be displayed.
The fan control will remain in the automatic control
mode unless you turn the AUTO FAN knob to select a
manual fan speed.
UPPER: This setting directs airflow through the
upper air outlets located in the instrument panel and
door panels.
BI-LEVEL: This setting directs the airflow
through both the upper air outlets and the lower floor
outlets. There is also a small amount of air directed to
the front defroster and the side window defrosters.
HEAT: This setting directs most of the airflow to
the lower floor outlets with some airflow directed to the
side window defrosters. There is also a small amount of
airflow directed to the front defroster.

3-6 Air Conditioning
The air conditioner cools, dehumidifies and filters the
air for the inside of the vehicle.
The air conditioning compressor is enabled in all modes
unless the A/C ON button is in the off position (the
indicator light will not be illuminated). However, the air
conditioning compressor will not operate when the
outside temperature is below 42
F (7
C). When the air
conditioner is on, you may sometimes notice slight
changes in your vehicle's engine speed and power. This
is normal, because the system is designed to cycle the
compressor on and off to keep the desired cooling and
help fuel economy.
On very hot days, open the windows long enough to let
the hot air out. This reduces the time required to cool the
interior of the vehicle to a comfortable level. If the
system is in the automatic mode (AUTO
-PUSH knob
indicator light is on), during very hot days the system
will automatically go to the RECIRC ON mode and the
temperature door will be positioned at the full cold
position for maximum cooling. You can choose the
extreme comfort setting of 60
F (16
C), but the
system will not cool any faster by choosing the extreme
comfort setting.
Heating
In cold weather, if the automatic mode is selected
(AUTO
-PUSH knob indicator light is on), the system
will automatically direct the airflow out of the lower
floor outlets and the temperature door will be positioned
at the full hot position. You can choose the extreme
comfort setting of 90
F (32
C), but the system will not
warm up any faster by selecting the extreme
comfort setting.
In cold weather, the system will delay turning on the fan
to avoid blowing cold air. The length of the delay
depends on the engine coolant temperature and the
outside temperature. The fan speed will increase as the
temperature of the engine coolant increases. Turning the
AUTO FAN knob will override this delay by turning off
the automatic fan control mode and changing the
fan speed.

NOTICE:
Before you add any sound equipment to your
vehicle
-- like a tape player, CB radio, mobile
telephone or two
-way radio -- be sure you can
add what you want. If you can, it's very
important to do it properly. Added sound
equipment may interfere with the operation of
your vehicle's engine, Delco Electronics radio or
other systems, and even damage them. Your
vehicle's systems may interfere with the
operation of sound equipment that has been
added improperly.
So, before adding sound equipment, check with
your dealership and be sure to check Federal
rules covering mobile radio and telephone units.
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 aren't, they may not operate
properly or may cause failure of the tape player.
Your tape player should be cleaned regularly after every
50 hours of use. Your radio may display CLN to indicate
that you have used your tape player for 50 hours without
resetting the tape clean timer. If this message appears on
the display, your cassette tape player needs to be
cleaned. It will still play tapes, but you should clean it as
soon as possible to prevent damage to your tapes and
player. If you notice a reduction in sound quality, try a
known good cassette to see if it is the tape or the tape
player at fault. If this other cassette has no improvement
in sound quality, clean the tape player.
The recommended cleaning method for your cassette
tape player is the use of 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 (GM Part No. 12344789).

If your engine ever stops while you're driving, brake
normally but don't pump your brakes. If you do, the
pedal may get harder to push down. If your engine
stops, you will still have some power brake assist. But
you will use it when you brake. Once the power assist is
used up, it may take longer to stop and the brake pedal
will be harder to push.
Anti-Lock Brakes (ABS)
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine and begin to drive away,
your anti
-lock brake system will check itself. You may
hear a momentary motor or clicking noise while this test
is going on, and you may even notice that your brake
pedal moves a little. This is normal.
If there's a problem with the
anti
-lock brake system, this
warning light will stay on.
See ªAnti
-Lock Brake
System Warning Lightº in
the Index.
Here's how anti-lock works. Let's say the road is wet.
You're driving safely. Suddenly an animal jumps out in
front of you.
You slam on the brakes. Here's what happens with ABS.
A computer senses that wheels are slowing down. If one
of the wheels is about to stop rolling, the computer will
separately work the brakes at each front wheel and at
both rear wheels.

The anti-lock system can change the brake
pressure faster than any driver could. The computer
is programmed to make the most of available tire and
road conditions.
You can steer around the obstacle while braking hard.As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
Remember: Anti
-lock doesn't change the time you need
to get your foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle in
front of you, you won't have time to apply your brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though you have
anti
-lock brakes.
Using Anti
-Lock
Don't pump the brakes. Just hold the brake pedal
down firmly and let anti
-lock work for you. You may
hear a motor or clicking noise during a hard stop, but
this is normal.
Traction Control System
Your vehicle has a traction control system that limits
wheel spin. This is especially useful in slippery road
conditions. The system operates only if it senses that
one or both of the front wheels are spinning or
beginning to lose traction. When this happens, the
system works the front brakes and reduces engine
power to limit wheel spin.
