1994 Oldsmobile Cutlass Supreme check engine light

joy riders or professional thieves - so
don’t do it.
When you park your Oldsmobile and
open the driver’s door, you’ll hear a
tone reminding you to remove your key
from the ignition and take it with you.
Always do this. Your steering wheel will
be locked, and
so will your ignition and
transaxle. And remember to lock the
doors.
Parking at Night
Park in a lighted spot, close all windows
and lock your vehicle. Remember to
keep your valuables out of sight. Put
them in
a storage area, or take them
with you.
Parking Lots
If you park in a lot where someone will
be watching your vehicle, it’s best to
lock it up and take your keys. But what
if you have to leave your ignition key?
What if you have to leave something
valuable in your vehicle?
Put your valuables in a storage area,
like your trunk or glove box.
Lock all the doors except the driver’s.
Then take the door key with you.
PASS-Key@ll
Your vehicle is equipped with the
PASS-ICey@II (Personalized
Automotive Security System) theft
deterrent system. PASS-ICey@II is a
passive theft deterrent system. This
means you don’t have to do anything
different to arm or disarm the system. It
worlts when you insert or remove the
ltey from the ignition. PASS-I uses a resistor pellet in the ignition key
that matches a decoder in your vehicle.
When the PASS-Keys11 system senses
that someone is using the wrong ltey, it
shuts down the vehicle’s starter and fuel
systems. For about three minutes, the
starter won’t work and fuel won’t go to
the engine. If someone tries to start
your vehicle again or uses another key
during this time, the vehicle will not
start. This discourages someone
from
randomly trying different keys with
different resistor pellets in an attempt to
make
a match. The
ignition key must be clean and dry
before it’s inserted in the ignition
or the
engine may not start. If the engine does
not start and the
SECURITY light is
on, the key may be dirty or wet. Turn
the ignition
off.
Clean and dry the ltey. Wait about three
minutes and try again. The security
light may remain on during this time. If
the starter still won’t work, and the ltey
appears to be clean and dry, wait about
three minutes and try the other ignition
ltey. At this time, you may also want to
check the fuses (see
Fuses G Circuit
Breakers
in the Index). If the starter
won’t work with the other ltey, your
vehicle needs service. If your vehicle
does start, the first ignition key may be
faulty. See your Oldsmobile dealer
or a
locksmith who can service the PASS-
I If you accidentally use a ltey that has a
damaged or missing resistor pellet, the
starter won’t work, and the
SECURITY light will come on. But you
don’t have to wait three minutes before
trying one
of the other ignition keys.

Low Engine Oil- Level Warning
Light
(omorv)
Your engine may be equipped with an
oil level monitoring system. When. the
ignition key is turned on, the
LOW OIL
LEVEL light will briefly flash. If the
light stays
on, stop the vehicle on a level
surface and turn the engine off. Check
the oil level using the engine oil
dipstick. (See the
Index under Engine
Oil.) If the light does not flash, have the
low oil level sensor system repaired
so it
will be ready to warn you if there's a
problem.
NOTIC E:
The oil.leve1 monitoring system
only checks oil level during the
brief period between key on and
engine crank. It does not monitor
engine oil level when the engine is
running. Additionally, an oil level
check is only performed if the
engine has been turned off for a
considerable peri.od of time
allowing the oil normally in
circulation to drain back into the
oil pan.

If the anti-lock brake system warning
light stays on longer than normal after
you’ve started your engine, turn the
ignition
off. Or, if the light comes on
and stays on when you’re driving, stop
as soon as possible and turn the ignition
off. Then start the,engine again to reset
the system. If the light still stays on, or
comes on again while you’re driving,
your Oldsmobile needs service. If the
light
is on but not flashing and the
regular brake system warning light isn’t
on, you still have brakes, but you don’t
have anti-lock brakes.
SERVICE

Malfunction. Indicator Lamp
(Service Engine Soon Light)
A computer monitors operation of your
fuel, ignition and emission control
systems. This light should come on
when the ignition is on, but the engine
is not running, as a check to show you
it is working.
If it does not come on at
all, have it fixed right away. If it stays
on, or it comes on while you are driving,
the computer is indicating that you
have a problem.
You should take your
vehicle in for service soon.

NOTICE:
If you keep driving your vehicle
with this light on, after
a while the
emission controls won’t work as
well, your fuel economy won’t be as
good and your engine may not run
as smoothly. This could lead to
costly repairs not covered by your
warranty. CHECK
GAGES
1 ANTI-
Check Gages Light
When this light comes on it means one
of these four things:
You have approximately 3 gallons
(12 L) or less of fuel remaining in
your tank. Check your fuel gage.
Your oil pressure is low. Check your
oil pressure indicator.
Your engine is too hot. Check your
coolant temperature gage.
There is a problem with the charging
system.
Head-Up Displcly (OP~ONJ
If you have the optional Head-Up
Display (HUD), you can see the
speedometer reading, in English or
metric units, displayed “through” the
windshield. The
HUD also shows:
Turn signal indicator lights.
A high beam indicator symbol.
A CHECK GAUGES message. (For
low oil pressure, high coolant
temperature, high or low battery
voltage, and low fuel.)

I
CHECK GAUGES
I'
HUD shows these lights when they are
lit on the instrument panel.
When you sit straight in your seat, the
HUD image will appear slightly to the
right.
When the ignition key is turned to
Run,
all possible HUD images will come on
and look
lilce this. Then the Head-Up
Display will
operate normally.
NOITICE:
'Although the HUD image appears
to be near the front
of the vehicle,
do not use it as a parking aid. The
HUD was not designed for that
purpose.
If you try to use it that
way, such.as in a parking lot, you
may misjudge distance and
run into
something.

Your Driving and the Road
The exit sp leed is usu.alll J posted.
Reduce your speed according to your
speedometer, not to your sense
of
motion. After driving for any distance at
higher speeds, you may tend to think
you are going slower than you actually
are.
4 Before Leaving on a Long
Trip
Make sure you’re ready. Try to be well
rested.
If you must start when you’re
not
fr&- such as after a day’s work
- don’t plan to make too many miles
that first part of the journey. Wear
comfortable clothing and shoes
you can
easily drive in.
Is your vehicle ready for a long trip? If
you keep it serviced and maintained, it’s
ready
to go. If it needs service, have it
done before starting out. Of course,
you’ll find experienced and able service
experts in Oldsmobile dealerships all
across North America. They’ll be ready
and willing to help
if you need it.
Here are some things you can check
before a trip:
a
Windshield Washer Fluid: Is the
reservoir full? Are all windows clean
inside and outside?
Wiper Blades: Are they in good
Fuel, Engine Oil, Other Fluids: Have
Lights: Are they all working? Are the
shape?
you checked all levels?
lenses clean?
Tires: They are vitally impartant to a
safe, trouble-free trip.
Is the tread
good enough far long-distance
driving? Are the tires all inflated
to
the recommended pressure?
weather outlook along your route?
Should you delay your trip a short
time to avoid
a major storm system?
Maps: Do you have up-to-date maps?
Weather Forecasts: What’s the
I Highway Hypnosis
Is there actually such a condition as
“highway hypnosis”? Or is it just plain
falling asleep at the wheel? Call it
highway hypnosis, lack of~awareness, or
whatever.

Turn Signals When Towing a
Trailer
When you tow a trailer, your vehicle has
to have a different turn signal flasher
and extra wiring. The green arrows on
your instrument panel will flash
whenever you signal a turn or lane
change. Properly hooked up, the trailer
lights will also flash, telling other
drivers you’re about to turn, change
lanes or stop.
When towing
a trailer, the green arrows
on your instrument panel will flash for
turns even if the bulbs on the trailer are
burned out. Thus, you may think
drivers behind you are seeing your
signal when they are not. It’s important
to check occasionally to be sure the
trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade.
If you don’t shift down, you
might have to use your brakes so much
that they would get hot and no longer
work well. On
a long uphill grade, shift down and
reduce your speed to around
45 mph
(70 ltm/h) to reduce the possibility of
engine and transaxle overheating.
If you are towing a trailer and you have
an automatic transaxle with Overdrive,
you may want to drive in
3 instead of D
(or, as you need to, a lower gear).
Parking on Hills
You really should not park your vehicle,
with a trailer attached, on a hill.
If
something goes wrong, your rig could
start to move. People can be injured,
and both your vehicle and the trailer
can be damaged.
But if you ever have to park your rig on
a hill, here’s how to do it:
1. Apply your regular brakes, but don’t
shift into
P (Park) yet.
2. Have someone place choclts under
the trailer wheels.
3. When the wheel choclts are in place,
release the regular brakes until the
choclts absorb the load.
4. Reapply the regular brakes. Then
apply your parking brake, and then
shift to
P (Park).
5. Release the regular brakes.
When You Are Ready to Leave
After Parking on a Hill
1. Apply your regular brakes and hold
the pedal down while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear
of the chocks.
4. Stop and have someone pick up and
store the chocks.

Service & Appearance Care
Engine Oil
If the LOW OIL LEVEL light on the
instrument panel comes
on, it means
you need to check your engine oil level
right away. For more information, see
Low Oil Level Light in the Index. You
should check your engine oil level
regularly; this is an added reminder.
It’s a good idea to check your engine .oil
:
every time you get fuel. In order to get
an accurate reading, the oil must be
warm and the vehicle must be on level
ground.
Turn
off the engine and give the 0il.a
few minutes to drain back into the
oil
pan. If you don’t, the oil dipstick might
not show the actual level.
To Check Engine Oil
Pull out the dipstick and clean it with-a
paper towel or cloth, then push it bzck
in all the way. Remove it again, keeping
the tip lower, and check the level.

When to Add Oil
If the oil is at or below the ADD line,
then you’ll need to add some
oil. But
you must use the right kind. This
section explains what kind
of oil to use.
For crankcase capacity, see
Capacities
and Specifications
in the Index.
NOTICE:
Don’t add too much oil. If your
engine has
so much oil that the oil
level gets above the cross-hatched
area that shows the proper
operating range, your engine could
be damaged.
Just fill it enough to put the level
somewhere in the proper operating
range. Push the dipstick all the way
back in when you’re through.
