Your vehicle 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. Dealer or qualified service center diagnosis
and service is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.

The following may prevent more serious damage to
your vehicle:
Reduce vehicle speed.
‘ Avoid hard accelerations.
Avoid steep uphill grades.
0 If 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. 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
previous steps, and drive the vehicle to your dealer
or
qualified service center for service.
If the Light Is On Steady I
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 evaporate 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 dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.
Oil Pressure Gage
0 \ 80
The oil pressure gage
shows the engine oil
pressure in psi (pounds
per square inch) when the
engine is running. Canadian
vehicles indicate pressure
in kPa (kilopascals).
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a
dangerously low oil level or other problem'causing low
oil pressure. Check your oil as soon as possible.
2-65

Downloaded from www.Manualslib.com manuals search engine 1 CAUTION:
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.
I NOTICE:
Damage to your engine from neglected oil
problems can be costly and
is not covered by
your warranty.

If the light comes on and stays on while you are driving,
it could indicate a problem with your vehicle. It could be
a problem with your oil pressure, coolant temperature,
or some other problem. Check your various gages to see
if they are in the warning zones.
If they are, have your
vehicle serviced right away.
Headlamp High-Beam Indicator Light
