1997 Oldsmobile Achieva engine

Charging System Indicator Light
The charging system indicator light will come on
when you start the engine,
then it should go out.
+I
If it stays on, or comes on while you are driving, you
may have a problem with the electrical charging system.
It could indicate that you have a loose generator drive
belt or another electrical problem. Have it checked
right away. Driving while this light is on could drain
your battery.
If you must drive a short distance with the light on, be
certain
to turn off all your accessories, such as the radio
and air conditioner.
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 working well.
If
the warning light comes on, there could be a brake
problem or the brake fluid level could be low. Have your
brake system inspected right away.
BRAKE
I II
United States Canada
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.
2-62

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, have the
vehicle towed for service. (See “Towing Your Vehicle”
in the Index.)
-: CAUTION:
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 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 stays on, turn the ignition to
OFF. Or, if the
light comes
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 regular brake system warning light
isn’t
on, you still have brakes, but you don’t have
anti-lock brakes.
If the regular brake system warning
light is also on, you don’t have anti-lock brakes and
there’s a problem with your regular brakes. See “Brake
System Warning Light” earlier in this section.
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.

Enhanced Traction System Warning Light
(If Equipped)
ETS
OFF
With the Enhanced Traction System
(ETS), this warning
light should come on briefly
as you start the engine. If
the warning light doesn’t
come on then, have it fixed
so it will be ready to warn
you if there’s a problem.
If
it stays on, or comes on when you’re driving, there
may be a problem with your Enhanced Traction System
and your vehicle may need service. When this warning
light is on, the system will not limit wheel spin. Adjust
your driving accordingly. The Enhanced Traction System warning light
may come
on for the following reasons:
If you turn the system off by pressing the button on
the instrument panel, the warning light will come on
and stay on.
To turn the system back on, press the
button again. The warning light should go
off. (See
“Enhanced Traction System’’ in the Index for more
information.)
0 The warning light will come on when you set your
parking brake with the engine running, and it will
stay on
if your parking brake doesn’t release fully. If
the system is turned on and the warning light stays on after your parking brake
is fully released, it
means there’s a problem with the system.
If the Enhanced Traction System warning light comes
on and stays on for an extended period
of time when the
system
is turned on and the parking brake is fully
released, your vehicle needs service.
2-64

Enhanced Traction System Active Light
(If Equipped)
LOW
TRAC
When your Enhanced
Traction System is limiting
wheel spin, this light will
come on. Slippery road
conditions may exist
if the
Enhanced Traction System active light comes on,
so
adjust your driving
accordingly.
Engine Coolant Temperature Gage
W
This gage shows the engine
coolant temperature.
If the
gage pointer moves into
the red area, your engine
is too hot! It means that
your engine coolant
has overheated.
The light will stay on for a few seconds after the
Enhanced Traction System stops limiting wheel spin.
The Enhanced Traction System active light also comes 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
there to tell you when the system is active. 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.
2-65

Low Coolant Warning Light
--I If this light comes on and
LOW
COOLANT
stays on, the vehicle should
promptly be pulled off
the road and the coolant
level checked.
See “Engine Coolant’’ in the Index. If there are visible
signs
of steam, see “Engine Overheating” in the Index
before opening the hood. Have your vehicle serviced as
soon as you can.
Malfunction Indicator Lamp
(Check Engine
Light)
CHECK
ENGINE
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 CHECK ENGINE 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. This may
prevent more serious damage to your vehicle. This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.
2-64

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:
0
0 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.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
0 Reducing vehicle speed.
0 Avoiding hard accelerations.
Avoiding steep uphill grades.
If you are 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. Find a safe place to park your vehicle.
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 Lipht Is On Steady
YOU may be ame to correct the emission system
malfunction by considering the following:
Did you recently 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. A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere.
A few driving trips with the cap properly
installed 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. 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 one or more of these conditions,
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
This light tells you if there
could be a problem with
your engine oil pressure.
This light can come on briefly, which is normal and
doesn’t show a problem:
0 As a bulb check, the light comes on when you turn
your key
to RUN and goes off when the engine is
started. If it doesn’t, be sure to have it fixed so it will
be there
to warn you.
For the four cylinder engine, when idling at a stop
sign, the light may blink on and then off. In addition,
if you make
a hard stop, the light may come on for
a moment.
But, when this light comes on and stays on, it means oil
isn’t going through your engine properly.
You could be
low on oil, or you might have some other oil problem.
Don’t keep driving
if the oil pressure is low. If
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.
