Oil Pressure lndicafor
This indicator tells you if there could be
a problem with your engine oil pressure.
The pointer should be above the red
zone when the engine
is running.
Readings in the red area tell you that
the engine is low on oil, or that you
might have some other oil problem. See
the
Index under Engine Oil.
NOTICE:
Damage to your engine from
neglected oil problems can be costly
and is not covered by your
warranty.

When the engine is running, the gage
shows the condition of the charging
system. Readings between the red
warning zones indicate the normal
operating range.

indicate a possible problem in the
electrical system.
Have your vehicle
serviced immediately.
When your engine is not running, but
the ignition is on (in the
Run position),
the gage shows your battery's state
of
charge.

lit on the instrument panel.

Care of the Head-Up Display
Clean the inside of the windshield as
needed to remove any dirt or film that
reduces the sharpness or clarity of the
HUD image.
To Clean the HUD:
Spray household glass cleaner on a soft,
clean cloth. Wipe the HUD lens gently,
then
dry it. Do not spray cleaner
directly on the lens, because the cleaner
fluid could leak inside the unit
if you do.
If You Can’t See the HUD Image
When the Ignition
is On:
Is anything covering the HUD unit?
Is the HUD dimmer control close
Is the HUD image adjusted to the
enough
to
MAX?
proper height?
Still no HUD image? Check the fuse
in the
CLSTR position in the glove
box fuse panel. See the Index under
Fuses G Circuit Breakers.
If the HUD Image is Not Clear:
It could be too bright. Move the HUD
dimmer control closer
to OFF.
You may need to clean the windshield
and HUD lens.
Your windshield is part of the HUD
system. If you ever have to have
a new
windshield, be sure to get one designed
for HUD. If you don’t, the HUD image
may look blurred and out of focus.
