File System and Naming
The song name that displays is the song name that is
contained in the ID3 tag. If the song name is not present
in the ID3 tag, then the radio displays the file name
without the extension (such as .mp3) as the track name.
Track names longer than 32 characters or four pages
are shortened. The display does not show parts of words
on the last page of text and the extension of the
filename is not displayed.
Preprogrammed Playlists
CDs that have preprogrammed playlists that were
created using WinAmp™, MusicMatch™, or Real
Jukebox™ software can be accessed, however, there is
no playlist editing capability using the radio. These
playlists are treated as special folders containing
compressed audio song files.
Playlists that have an .m3u or.pls file extension and are
stored on a USB device may be supported by the
radio with a USB port.

To remove the fuel cap, turn it slowly counterclockwise.
The fuel cap has a spring in it; if the cap is released
too soon, it will spring back to the right.
While refueling, hang the tethered fuel cap from the
hook on the fuel door.
{WARNING:
Fuel can spray out on you if you open the fuel cap
too quickly. If you spill fuel and then something
ignites it, you could be badly burned. This spray
can happen if the tank is nearly full, and is more
likely in hot weather. Open the fuel cap slowly and
wait for any hiss noise to stop. Then unscrew the
cap all the way.Be careful not to spill fuel. Do not top off or overfill the
tank, and wait a few seconds after you have finished
pumping before removing the nozzle. Clean fuel from
painted surfaces as soon as possible. SeeWashing Your
Vehicle on page 6-110.
When replacing the fuel cap, turn it clockwise until it
clicks. Make sure the cap is fully installed. The diagnostic
system can determine if the fuel cap has been left off or
improperly installed. This would let fuel evaporate into
the atmosphere. SeeMalfunction Indicator Lamp on
page 4-34.
The CHECK GAS CAP message displays on the Driver
Information Center (DIC) if the fuel cap is not properly
installed. SeeDIC Warnings and Messages on
page 4-42for more information.

How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to change
the engine oil and filter based on vehicle use. Whenever
the oil is changed, reset the system so it can calculate
when the next oil change is required. If a situation occurs
where the oil is changed prior to a CHANGE OIL SOON
message being turned on, reset the system.
After changing the engine oil and filter, the system must
be reset. To reset the oil life system:
1. With the CHANGE OIL SOON message displayed,
press any of the three DIC buttons to clear the
CHANGE OIL SOON message. SeeDIC Warnings
and Messages on page 4-42.
2. Display OIL LIFE RESET on the DIC.
3. Press and hold the ENTER button for at least
one second. An ACKNOWLEDGED display
message will appear for three seconds or until the
next button is pressed. This tells you the system
has been reset. SeeDIC Vehicle Personalization
on page 4-47.
4. Turn the ignition to LOCK/OFF.
If the CHANGE OIL SOON message comes back on
when the vehicle is started, the engine oil life system
has not reset. Repeat the procedure.
What to Do with Used Oil
Used engine oil contains certain elements that can be
unhealthy for your skin and could even cause cancer.
Do not let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a good hand
cleaner. Wash or properly dispose of clothing or rags
containing used engine oil. See the manufacturer’s
warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from the
filter before disposal. Never dispose of oil by putting it
in the trash, pouring it on the ground, into sewers, or into
streams or bodies of water. Recycle it by taking it to a
place that collects used oil.

If No Steam Is Coming From The
Engine Compartment
If an engine overheat warning is displayed but no steam
can be seen or heard, the problem may not be too
serious. Sometimes the engine can get a little too hot
when the vehicle:
•Climbs a long hill on a hot day.
•Stops after high-speed driving.
•Idles for long periods in traffic.
•Tows a trailer.
If the overheat warning is displayed with no sign of
steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and
to the highest fan speed. Open the windows as
necessary.
3. In heavy traffic, let the engine idle in N (Neutral)
while stopped. If it is safe to do so, pull off the
road, shift to P (Park) or N (Neutral) and let
the engine idle.If the temperature overheat gage is no longer in the
overheat zone or an overheat warning no longer
displays, the vehicle can be driven. Continue to drive
the vehicle slow for about 10 minutes. Keep a safe
vehicle distance from the car in front of you. If the
warning does not come back on, continue to drive
normally.
If the warning continues, pull over, stop, and park the
vehicle right away.
If there is no sign of steam, idle the engine for
three minutes while parked. If the warning is still
displayed, turn off the engine until it cools down.
Also, see “Overheated Engine Protection Operating
Mode” next in this section.
