can, it means that the shift lever wasn’t
fully locked into
P (Park).
Torque Lock
If you are parking on a hill and you
don’t shift your transaxle into
P (Park)
properly, the weight of the vehicle may
put too much force on the parking pawl
in the transaxle. You-may find it
difficult to pull the shift lever out.of
P
(Park). This is called “torque lock.” To
prevent torque lock, set the parking
brake and then shift into
P (Park)
properly before you leave the driver’s
seat.
To find out how, see Shifting Into.
P (Park) in the.Index.
When you are ready to drive; move the
shift lever out of
P (Park) BEFORE you
release the parking brake.
If “torque lock” does occur, you may
need to have another vehicle push yours
a little uphill to take some of the
pressure from the transaxle,
so you can
pull the shift lever out of
P (Park).

The tachometer displays the engine

NOTICE:
Do not operate the engine with the
tachometer in the red area, or
engine damage may occur.

Fuel Gage
Your fuel gage tells you about how
much fuel you have left, when the
ignition is on. When the indicator nears
E (Empty), you still have a little fuel left,
but yonshould get more soon.
Here arethree things that some owners
ask about. None of these show a
problem
with your fuel gage:
At the gas station, with your ignition
on, the gas pump shuts
off before the
gage reads
F (Full).
It takes a little more or less fuel to fill
up than the gage indicated. For
example, the gage may have indicated
the tank was half full, but it actually
took a little more or less than half the
tank’s capacity to fill the tank.
The gage moves a little when you turn
a corner or speed up.
For your fuel tank capacity, see

Engine Coolant Temperafure
Gage
You have a gage that shows the engine
coolant temperature. If the gage pointer
moves into the red area, your engine is
too hot!
That reading means the same thing as
the warning light. 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.

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.

Oil Pressure lndicafor
This indicator tells you if there could be
a problem with your engine oil pressure.
The pointer should be above the red
zone when the engine
is running.
Readings in the red area tell you that
the engine is low on oil, or that you
might have some other oil problem. See
the
Index under Engine Oil.
NOTICE:
Damage to your engine from
neglected oil problems can be costly
and is not covered by your
warranty.
Volfmefer
When the engine is running, the gage
shows the condition of the charging
system. Readings between the red
warning zones indicate the normal
operating range.
Readings in either red warning zone
indicate a possible problem in the
electrical system.
Have your vehicle
serviced immediately.
When your engine is not running, but
the ignition is on (in the
Run position),
the gage shows your battery's state
of
charge.

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

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.

Air Conditioning
On very hot days, open the windows
long enough to let hot inside air escape.
This reduces the time it takes for your
vehicle to cool down, which should help
fuel economy.
There are three
air conditioning settings:
MAX: Provides maximum cooling or
quick cool-down on very hot days. This
setting also helps prevent outside odors
from entering your vehicle.
This setting recirculates much of the air
inside your vehicle, and it should not be
used for long periods because the air
may become too cold and dry. This
setting is not recommended if an
occupant is smoking.
NORM: Use for normal cooling on hot
days. This setting brings in outside air, cools
it and directs it through the
instrument panel outlets.
BI-LEV (Bi-Level): Use on cool, but
sunny days. This setting brings in
outside air, but directs it in two ways.
The cool air is directed to the upper
portion of your body through the
instrument panel outlets, but most
warmed air is directed through the
heater ducts and a little to the defrost
and side window vents. At times this
temperature difference may be more
apparent than others.
Heating and Ventilation
When you don’t need to cool the
outside air, use these next settings. You
can leave the air as it is or heat it.
The air conditioner compressor doesn’t
run in these settings. This reduces the
engine load, resulting in improved fuel
economy (gas mileage).
VENT: For mild outside temperatures,
when little heating or cooling is needed,
push
VENT. Air flow is through the
instrument panel outlets. Slide the
temperature control lever to a
comfortable level.
