Malfunction Indicator Lamp

Service Engine Soon Light
First, you will not notice any difference in engine
performance, but your tail pipe emissions may increase.
Second, your engine may not run properly or may
stall without warning. If either of these things happen,
drive or tow your vehicle to your dealer for service.
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 repaired.
Notice: If you keep driving your vehicle with this
light on, after awhile, 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.

If this light comes on
or flashes while you
are driving, two things
may happen.

Oil Pressure Gage

United States
The engine oil pressure gage, on the lower right portion
of your instrument panel cluster, shows engine oil
pressure in psi (pounds per square inch) or in kPa
(kilopascals). Oil pressure may vary with outside
temperature and oil viscosity, but readings of
30 to 40 psi (205 to 275 kPa) are normal. The normal
operating range should be between 35 and 70 psi
(240 to 480 kPa).
A reading in the low pressure zone may be caused by a
dangerously low oil level or other problem. See
Engine Oil on page 5-14 and Scheduled Maintenance
on page 6-5 for more information.
