1996 OLDSMOBILE AURORA engine

If the coolant temperature is over 261 OF ( 127 O 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.
In “Problems on the Road,” this manual shows 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 (&-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, which
may prevent more serious damage
to your vehicle. This
system is also designed
to assist your service technician
in correctly diagnosing any malfunction.
ProCarManuals.com

The following may prevent more serious damage to
your vehicle: I 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:
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.
0 Reduce vehicle speed.
0 Avoid hard accelerations.
0 Avoid steep uphill grades.
If 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. Put your vehicle in PARK (P). 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.

If the Light Is On Steady
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. Have you recently
changed brands of fuel?
If
so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel quality will cause your
engine not to run
as efficiently as designed. You may
notice this as stalling after start-up, stalling when
you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause
the light
to
turn on.
If you experience this condition, change the fuel brand
you use.
It will require at least one full tank of the
proper fuel
to turn the light off.
If none of the above steps have made the light turn off,
have your retailer or qualified service center check the
vehicle. Your retailer has the proper test equipment and
diagnostic tools
to fix any mechanical or electrical
problems that may have developed.

Oil Pressure Warning Light
OIL
If you have a problem with
your oil, this light may stay
on after you start your
engine, or come on when
you are driving.
A warning
chime and the message
LOW OIL PRESSURE may
also come on.
These indicate that oil is not going through your engine
quickly enough
to keep it cool. The engine could be low
on oil, or could have some other oil problem. Have it
fixed right away.
The
oil light could also come on in three other
situations:
When the ignition is on but the engine is not running,
the light will come on as a test to show you
it is
working, but the light will go out when you
turn the
ignition to START.
If it doesn't come on with the
ignition on, you may have a problem with the fuse or
bulb. Have it fixed right away.
Sometimes when the engine is idling at a stop, me
light may blink
on and off. This is normal.
If you make a hard stop, the light may come on for a
moment. This is normal.
Don't keep driving if the oil pressure is low. ir
you do, your engine can become so hot that it
catches fire.
You or others could be burned.
Check your
oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and
is not covered by
your warranty.

transaxle fluid change.
The Driver Information Center 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 “Engine Oil” 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 “Engine Oil” 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.

Automatic Operation
Press the AUTO-PUSH knob when you want the system
to automatically adjust to changes in the temperature
inside the vehicle, the outside temperature and the sun
load on the vehicle. When the system
is set for 4%
automatic operation, air will come from the floor, upper
or the windshield outlets depending on the temperature
inside the vehicle, the outside temperature and the sun
load. Fan speed will vary as the system reaches and
.................
maintains the comfort setting you have selected.
. 7* -
....................................................................... \
To find your comfort setting, start with the system in
automatic mode by depressing the AUTO-PUSH knob.
Adjust
the comfort setting by using the red and blue
buttons located below the digital display until you reach a
value of
75 OF (24"C), on the display. Give the vehicle
about
20 minutes to stabilize and then adjust the comfort
setting
if necessary, through the use of the red and blue
buttons. The display will show
the comfort setting for five
seconds and then it will show the outside temperature.
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. Rotating 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 towards 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, hold
down the OFF button located in the Driver Information
Center for five seconds. The display in the Driver
Information Center will also change from an English to
a Metric display.
To return to an English display, repeat
the above procedure.
