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.

Engine Oil Pressure Gauge
This gauge tells you if there could be a
problem with your engine oil pressure.
The engine oil pressure gauge shows the
engine oil pressure in psi (pounds per
square inch) or kPa (kilopascals) when
the engine is running. Oil pressure
should be 20 to 80 psi (140 to 550 kPa).
It may vary with engine speed, outside
temperature and oil viscosity, but readings
above the shaded area show the normal
operating range. Readings in the shaded
area tell you that the engine is low on oil,
or that you might have some other oil
problem. See "Engine Oil" in the Index.
