I
A computer monitors
operation
of your fuel,
ignition and emission
control systems. This amber
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

OIL
PRESS
PSI
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 Ea). 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.

SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is best
for your vehicle. However, you can
use SAE
1OW-30 if it’s going to be 0°F (-1S.OC) or above.
These numbers on an
oil container show its viscosity,
or thickness.
Do not use other viscosity oils such as
SAE
20W-50.
Oils meeting these
requirements should also
have the “Starburst” symbol
on the container.
The “Starburst” symbol indicates that the
oil has been
certified by the American Petroleum Institute (API), and
is preferred for your gasoline engine. These oils may
also be identified
as API SH.

USAGE
Engine Oil
FLUIDLUBRICANT
The engine requires a special oil
meeting GM Standard GM4718M.
Oils meeting this Standard may be
identified as synthetic, and should also be identified with the
American Petroleum Institute Certified For Gasoline Engines
“Starburst” symbol. However, not
all Synthetic API oils with the
“Starburst” symbol will meet this
GM Standard. You should look for
and use only an oil that meets GM
Standard GM4718M. For the
proper viscosity, see “Engine Oil”
in the Index.
