LOCK (B): Before you put the key into the ignition
switch, the switch is in the
LOCK position. It’s also the
only position in which you can remove your key. This
position locks your ignition, steering wheel and
transaxle. It’s a theft-deterrent feature.
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. It doesn’t lock the steering
wheel like
LOCK. Use OFF if you must have your
vehicle pushed or towed.
RUN (D): This position is where the key returns after
you start your vehicle. With the engine off, you can
use
RUN to display some of your warning and
indicator lights.
START (E): This position starts your engine.
A warning chime will sound if you open the driver’s
door when the ignition is in the
OFF, LOCK or ACC
position and the key is in the ignition.
NOTICE:
If your key seems stuck in LOCK and you can’t ,
turn it, be sure it is all the way in. If it is, then
turn the steering wheel left and right while you
turn the key hard.
But turn the key only with
your hand. Using a tool to force it could break
the key or the ignition switch.
If none of this
works, then your vehicle needs service.

Daytime Running Lamps
Daytime Running Lamps (DIU) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset.
A light sensor on top of the instrument panel makes the
DRL work,
so be sure it isn't covered.

Warning Lights, Gages and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something
is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you
will see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to let you know they’re working. If you are
familiar with this section, you should not be alarmed
when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages and
warning lights work together to let you know when
there’s a problem with your vehicle. When
one of the warning lights comes on and stays on
when you
are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual’s advice.
Waiting to do repairs can be costly
-- and even
dangerous.
So please get to know your warning lights
and gages. They’re a big help.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for about eight seconds
to remind people to
fasten their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay
on until the driver’s belt
is buckled.

Brake System Warning Light
Your Oldsmobile’s hydraulic brake system is divided
into two parts. If one part isn’t working, the other part
can still work and stop you. For good braking, though,
~ you need both parts workmg well.
If the warning light comes on, there could be
a brake
problem. Have your brake system inspected right away.
BRAKE
This light should come on
briefly when you turn the
ignition key to
RUN. If it
doesn’t come on then,
have
it fixed so it will be
ready to warn you if
there’s a problem.
If the light comes on while you
are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push.
Or, the pedal may go closer to the floor.
It may take longer to stop. If the light is still on, or if the anti-lock brake system warning light
is flashing, have
the vehicle towed for service. (See “Anti-Lock Brake
System Warning Light” and “Towing Your Vehicle” in
the Index
.)
1 C.’ UTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on or if the
anti-lock brake system warning light is flashing
after you’ve pulled
off the road and stopped
carefully, have the vehicle towed for service.
When the ignition is on, the brake system warning light
will also come on when
you set your parking brake. The
light will stay on if your parking brake doesn’t release
fully. If it stays on after your parking brake is fully
released, it means you have a brake problem.

Anti-Lock Brake System Warning Light
With the anti-lock brake system, this light will come
on when you start your
engine and it will stay
on for three seconds.
That’s normal.
If the light flashes when you’re driving, you don’t have
anti-lock brakes and there could be
a problem with your
regular brakes. Pull
off the road and stop carefully. You
may notice that the pedal is harder to push. Or, the pedal
may go closer to the floor. It may take longer to stop.
Vehicle” in the Index.)
, Have the .vehicle towed for service. (See.“Towing Your
Your regular brake system may not be working
properly
if the anti-lock brake system warning
light is flashing. Driving with the anti-lock brake system warning light flashing can lead to an
accident. After you’ve pulled
off the road and
stopped carefully, have the vehicle towed
for service.
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.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to
RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready
to warn you if there is a problem.

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.

~ ~~~~
~ ~~~ ~ Avoid needless heavy braking.
Some people drive
in spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. This is a
mistake. Your brakes may not have time to cool between
hard stops. Your brakes will wear out much faster if you
do a lot of heavy braking. If you keep pace with the
traffic and allow realistic following distances, you will
eliminate a lot
of unnecessary braking. That means
better braking and longer brake life.
If your engine ever stops while you’re driving, brake
normally but don’t pump your brakes. If you do, the
pedal may get harder to push down.
If your engine
stops, you will still have some power brake assist. But
you will use it when you brake. Once the power assist is
used up, it may take longer to stop and the brake pedal
will be harder to push.
_. ~~~~ ~ ~~

Anti-Lock Brakes
Your
vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine, or when you begin to drive away, your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that your
brake pedal moves a little. This is normal.
If there’s a problem with the
anti-lock brake system, this
warning light will stay on or
flash. See “Anti-Lock
Brake System Warning
Light” in the Index.
