Engine Oil Pressure GageThe engine oil pressure gage 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).
In certain situations such as long, extended idles on hot
days, it could read as low as 6 psi (40 kPa) and still
be considered normal. 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. SeeEngine Oil on page 5-16.
The engine oil pressure can also be displayed using the
GAGES button on the Driver Information Center (DIC).
SeeDriver Information Center (DIC) on page 3-48.
{CAUTION:
Do not keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be covered
by your warranty. Always follow the maintenance
schedule in this manual for changing engine oil. United States

Playing a CD (Single CD Player)
Insert a CD partway into the slot, label side up. The
player will pull it in and the CD should begin playing.
If the ignition or radio is turned off with a CD in the
player, it will stay in the player. When the ignition or
radio is turned on, the CD will start playing where
it stopped, if it was the last selected audio source.
When a CD is inserted, CD and the CD symbol
will appear on the display. As each new track starts
to play the track number will appear on the display.
The CD player can play the smaller 3 inch (8 cm)
single CDs with an adapter ring. Full-size CDs and
the smaller CDs are loaded in the same manner.
If playing a CD-R, the sound quality (and playback
performance) may be reduced due to the CD-R quality,
method of recording, the quality of the music that has
been recorded, and the way the CD-R has been handled.
For better playback performance when home burning
audio discs, use brand named CD media with the
[“Compact Disc” trade mark logo], and a burn rate no
faster than 12X.
There may be an increase in skipping, difficulty in
nding tracks, and/or difficulty in loading and ejecting.
If these problems occur, check the bottom surface of
the CD. If the surface of the CD is damaged, suchas cracked, broken, or scratched, the CD will not play
properly. If the surface of the CD is soiled, seeCare
of Your CDs on page 3-100for more information.
If there is no apparent damage, try a known good CD.
Do not add any label to a CD, it could get caught in the
CD player. If a CD is recorded on a personal computer
and a description label is needed, try labeling the top of
the recorded CD with a marking pen instead.
Notice:If you add any label to a CD, insert more
than one CD into the slot at a time, or attempt
to play scratched or damaged CDs, you could
damage the CD player. When using the CD player,
use only CDs in good condition without any
label, load one CD at a time, and keep the CD player
and the loading slot free of foreign materials,
liquids, and debris.
If an error appears on the display, see “CD Messages”
later in this section.
