the le structure that contains only
folders/subfolders and no compressed les directly
beneath them, the player advances to the next
folder in the le structure that contains compressed
audio les. The empty folder does not display.

playlist and continues sequentially through
all tracks in each playlist. When the last track
of the last playlist has played, play continues

Your dealer has GM-trained service people who
will perform this work using genuine GM parts and
reset the system. It is also important to check
your oil regularly and keep it at the proper level.

must change your oil at 3,000 miles (5 000 km)
since your last oil change. Remember to reset the
oil life system whenever the oil is changed.

The Engine Oil Life System calculates when to
change your engine oil and lter based on vehicle
use. Anytime your oil is changed, reset the
system so it can calculate when the next oil
change is required. If a situation occurs where you
change your oil prior to a CHANGE ENGINE
OIL SOON message coming on, reset the system.Always reset the engine oil life to 100% after
every oil change. It will not reset itself. To reset
the Engine Oil Life System, do the following:
1. Display the OIL LIFE REMAINING on the DIC.
If your vehicle does not have DIC buttons, the
vehicle must be in PARK (P) to access this
display. SeeDIC Operation and Displays (With
DIC Buttons) on page 268orDIC Operation
and Displays (Without DIC Buttons) on
page 275.
2. Press and hold the SET/RESET button on
the DIC, or the trip odometer reset stem if
your vehicle does not have DIC buttons,
for more than ve seconds. The oil life will
change to 100%.
If the CHANGE ENGINE OIL SOON message

Engine Oil Life System has not reset. Repeat
the procedure.
