n 100
Q
This gage shows the engine
coolant temperature.
If the gage pointer moves into the red warning zone,
your engine
is hot. To prevent engine overheating, the
air conditioning compressor will turn off automatically,
a fast-pulsed chime will sound, and the message
ENGINE
HOT. ..A/C OFF will appear in the information
center.
As the engine cools down, the air conditioning
compressor will automatically turn back on.
If the coolant temperature is over 26 1 OF ( 127’ C), the
message
HOT ... STOP ENGINE will appear. It means
that your engine coolant has overheated. If you have
been operating your vehicle under normal driving
conditions, you should pull
off the road, stop your
vehicle and turn
off the engine as soon as possible.
The section “Problems on the Road,” in this manual
explains what
to do. See “Engine Overheating” in
the Index.
If your coolant level is low, the message
LOW ENGINE
COOLANT will appear on the Driver Information
Center. Check your coolant level as soon as possible.
See “Engine Coolant” in the Index.

Malfunction Indicator Lamp
(Service Engine
Soon Light)
SERVICE
ENGINE SOON
Your Aurora is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD
I1 (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.
(In Canada, OBD I1 is replaced by
Enhanced Diagnostics.) 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.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition
is on and the engine is not
running.
If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
a
0
Light Flashing -- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Retailer or qualified service center diagnosis
and service is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Retailer or qualified service center diagnosis and
service may be required.

If the Light Is Flashing If the Light Is On Steady
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
Avoiding hard accelerations.
0 Avoiding steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light Is On Steady” following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key
off, wait at least 10 seconds and restart the
engine.
If the light remains on steady, see “If the Light
Is On Steady” following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
retailer or qualified service center for service.
You may be able to correct the emission system
malfunction by considering the following:
Did
you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should
turn the light off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the
fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly. It
will take a few driving trips to turn the light off.

Operating the RECIRC mode in cold temperatures or
under high humidity conditions may cause moisture
to
form on the inside of the windshield. If this condition
occurs, deselect the RECIRC button.
A/C ON: Press this button to turn the air conditioning
on and
off. If the system is operating in the automatic
mode, the A/C
ON indicator light will automatically
illuminate. In the auto mode, the A/C compressor will
only operate when the system determines
it is needed.
OFF: Rotate the AUTO-PUSH knob to OFF. Turning
the system off will cause the fan to turn off and the
airflow to be directed
out the lower floor outlets. The
system will still try to keep the interior of the vehicle at
the previously chosen comfort setting. The outside
temperature will show in the display when the system is set to
OFF.
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
(indicator light will not be illuminated). However, the
air conditioning compressor will not operate when the
outside temperature is below
44°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 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.

All of the CD functions are controlled by the radio
buttons except
for ejecting the magazine. Whenever a
CD magazine with discs is loaded in the changer, the
compact disc symbol (CDC) will appear on the radio
display.
If the CD changer is checking the magazine for
CDs, the (CDC) symbol will flash on
the display until
the changer is ready to play. When a CD begins playing,
a disc and track number will be displayed. The disc
numbers are listed on the front of the magazine.
Compact Disc Errors
If E and a number appear on the display, an error has
occurred and the compact disc temporarily cannot play.
The CD changer will send an error message to the
receiver
to indicate:
E34: CD Changer Door Open
E35: CD Changer Cartridge Empty
If the error occurred while trying to play a CD in the
compact disc player or changer, the following conditions
may have caused the error:
The road is too rough. The disc should play when the
road
is smoother.
0 The disc is dirty, scratched, wet or upside down.
The air is very humid. If so, wait about an hour and
try again.
The CD changer door is open. Completely close the
An empty magazine is inserted in the CD changer.
door to restore normal operation.
Try the magazine again with a disc loaded
on one of
the trays.
If any error occurs repeatedly or if an error cannot be
corrected, please contact your retailer. If your radio
displays an error number, write it down and provide it to
your retailer when reporting the problem.
Playing a Compact Disc
REV (1): Press and hold this button to quickly reverse
within a track.
As the CD reverses, elapsed time will be
displayed to help you find the correct passage.
FWD (2): Press and hold this button to quickly advance
within a track.
As the CD advances, elapsed time will be
displayed to help you find the correct passage.
PROG (3): Press this button to select the next disc in the
magazine. Each time
you press PROG, the disc number on
the radio display
will increment to the next available CD.
If a CD cannot be played, its number will be skipped
when selecting discs while using the PROG button.

Attach a separate
safety chain around the
outboard end of each
lower control arm.
Engine Overheating
You will find a coolant temperature gage on your
Aurora’s instrument panel. Your information center will
also display messages about engine overheating. See
“Coolant Temperature Gage” in the Index.
Overheated Engine Protection
Operating Mode
Should a low coolant condition exist and the message
HOT STOP ENGINE is displayed, an overheat
protection mode which alternates firing groups of four
cylinders helps prevent engine damage. In this mode,
you will notice a
loss in power and engine performance.
This operating mode allows your vehicle to be driven to
a safe place in an emergency; you may drive up to
50 miles (80 km). Towing a trailer in the overheat
protection mode should be avoided.
I NOTICE:
~ After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause of coolant loss, change the oil and reset
the oil life indicator. See “Engine Oil, When to
Change” in the Index.

If No Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no
steam, the problem may not be too serious..Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
0 Stop after high-speed driving.
0 Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign
of steam,
try this for a minute or
so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open
the window as necessary.
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about
10 minutes.
If the warning doesn’t come back on, you can
drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked, to see
if
the warning stops. But then, if you still have the
warning,
turn 0fSth.e engine and get everyone out
of the vehicle until it cools down. Also, see “Overheated
Engine Protection Operating Mode” listed previously in
this section.
You may decide not to lift the hood but to eet service
help right away.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (@)
or THIRD (3).

Adding Equipment to the Outside of Your
Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your Aurora retailer before adding equipment to the
outside of your vehicle.
Fuel
Use premium unleaded gasoline rated at 91 octane or
higher. At a minimum, it should meet specifications
ASTM D4814 in the United States and CGSB 3.5-M93
in Canada. Improved gasoline specifications have been
developed by the American Automobile Manufacturers
Association (AAMA) for better vehicle performance and engine protection. Gasolines meeting the AAMA
specification could provide improved driveability and
emission control system protection compared to
other gasolines.
Be sure the posted octane for premium is at least 9 1. If
the octane is less than 9
1, you may get a heavy knocking
noise when you drive. (In an emergency, you may be
able to use a lower octane
-- as low as 87 -- if heavy
knocking does not occur.)
If you’re using 91 or higher
octane unleaded gasoline and you hear heavy knocking,
your engine needs service.
If your vehicle is certified to meet California Emission
Standards (indicated on the underhood tune-up label), it
is designed to operate on fuels that meet California
specifications. If such fuels are not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp on
your instrument panel may turn on and/or your vehicle
may fail a smog-check test.
If this occurs, return to your
authorized Aurora retailer for diagnosis to determine the
cause of failure.
In the event it is determined that the
cause of the condition is the type of fuels used, repairs
may not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT);
ask your service station operator whether or not his fuel
contains MMT. General Motors does not recornend the
use of such gasolines.
If fuels containing MMT are used,
spark plug life may be reduced and your emission
control system performance may be affkcted. The
malfunction indicator lamp on your instrument panel
may turn on.
If this occurs, return to your authorized
Aurora retailer for service.
