PASS-Key I1 uses a resistor pellet in the ignition key
that matches a decoder in your vehicle.
When the PASS-Key I1 system senses that someone is
using the wrong key, 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 key. 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 key appears
to be clean and
dry, wait about three minutes and try
another ignition key. At this time, you may also want to
check the fuses (see “Fuses and Circuit Breakers” in the Index).
If the starter won’t work with the other key, your
vehicle needs service. If your vehicle does start, the first
ignition key may be faulty. See your Oldsmobile retailer
or a locksmith who can service the PASS-Key 11.
If you accidentally use a key 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 another ignition key.
See your Oldsmobile retailer or a locksmith who can
service the PASS-Key
I1 to have a new key made.
If you’re ever driving and the SECURITY light
comes on, you will be able to restart your engine
if
you turn it off. Your PASS-Key I1 system, however, is
not working properly and must be serviced by your
Oldsmobile retailer. Your vehicle is not protected by
the PASS-Key I1 system.
If you lose or damage a PASS-Key I1 ignition key, see
your Oldsmobile retailer or
a locksmith who can service
PASS-Key
11 to have a new key made.

Yneine Coolant Heater (Option)
In very cold weather,
0°F (- 18 O C) or colder,
the engine coolant heater
can help. You’ll get
I
easier starting and better
fuel economy during
engine warm-up.
A CAUTION:
Plugging the
could cause an electrical shock. Also, the wrong
kind
of extension cord could overheat and cause
a fire.
You could be seriously injured. Plug the
cord into a properly grounded three-prong
110-volt AC outlet.
If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least 15 amps.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your vehicle.
To Use the Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt AC outlet.
4. After you’ve used the coolant heater, be sure to
store the cord as it was before to keep it away
from moving engine parts.. If you don’t, it could
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead of
trying
to list everything here, we ask that you contact
your Oldsmobile retailer in the area where you’ll be
parking your vehicle. The retailer can give you the best
advice for that particular area.

AUTOMATIC OVERDRIVE (0): This position is for
normal driving. It is the ovetdrive position. If you need
more power for passing, and you’re:
- Going less than 35 mph (56 km/h), push your
accelerator ppdal about halfway down.
- Going about 35 mph (56 km/h) or more, push the
accelerator pedal all the way down.
You’ll shift down to the next gear and have
more power.
i
NOTICE:
If your vehicle seems to start up rather slowly,
or
if it seems not to shift gears as you go faster,
something may be wrong with
a transaxle system
sensor.
If you drive very far that way, your
vehicle can be damaged.
So, if this happens, have
your vehicle serviced right away. Until then, you
can use SECOND
(2) when you are driving less
than
35 mph (56 km/h) and AUTOMATIC
OVERDRIVE
(a) for higher speeds.
THIRD (3): This position is also used for normal
driving, but it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE
(0).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (0)):
- When driving on hilly, winding roads.
- When towing a trailer, so there is less shifting
- When going down a steep hill.
SECOND (2): This position gives you more power but
lower fuel economy. You can use SECOND
(2) on hills.
It can help control your speed
as you go down steep
mountain roads, but then you would also want to use
your brakes off and on.
between gears.

NOTICE:
Don’t drive in SECOND (2) for more than
25 miles (41 km) at speeds over 55 mph
(88 km/h), or you can damage your transaxle.
Use AUTOMATIC OVERDRIVE

THIRD
(3) as much as possible.
Don’t shift into SECOND
(2) unless you are going
slower than
65 mph (105 km/h), or you can
damage your engine.
FIRST
(1): This position gives you even more power
(but lower fuel economy) than
SECOND (2). You can
use it on very steep hills, or in deep snow or
mud. If the
shift lever is put in
FIRST (l), the transaxle won’t shift
into first gear until the vehicle is going slowly enough.
NOTICE:
If your front wheels can’t rotate, don’t try to
drive. This might happen if you were stuck in
very deep sand or mud or were up against.

Also,
if you stop when going uphill, don’t hold
your vehicle there with only the accelerator

transaxle. Use your brakes or shift into.PARK (P)

Malfunction Indicator Lamp (Service Engine Soon Light)
I
SERVICE
ENGINE SOON
Your Oldsmobile 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, which
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:
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.
Avoid steep uphill grades.
I 0 If towing a trailer, reduce the amount of cargo being
hauled as soon as it is possible.
If the lightstops 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
1 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 put fuel into your vehicle?
If
so, reinstall the fuel cap, making sure to fully install
the cap. The diagnostic system can determine if the fuel
cap has been left
off or improperly installed. This will
allow fuel to .evap.orate into the atmosphere. A few
driving trips should turn the light
off.
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 Warning Light c
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.
This indicates that oil is not going through your engine
quickly enough to keep it lubricated. The engine could
be low on oil or could have some other oil problem.
Have it fixed right away.

to
show you it’s working. If it
doesn’t come on then, have
it fixed.
