GMC 2007 Savana - Manual (Page 183)

Change Engine Oil Light
This light is displayed
when your vehicle
needs to be serviced.
If your vehicle has a V8 engine and this light is
flashing, it indicates that the oil level is low.
When this light is on steady, your vehicle needs to
be serviced. See Scheduled Maintenance
(Gasoline Engine) on page 399 for more
information.
Once the engine oil has been changed, the
change engine oil light must be reset. Until it is
reset, the light will stay on for a while each time the
engine is started. For more information on
resetting the system, see “How to Reset the
Engine Oil Life System” under Engine Oil
Life System (Gasoline Engine) on page 300.
Security Light
The light will stay on until the engine starts. If the
light flashes, the Passlock
® System has entered
a tamper mode. If the vehicle fails to start,
see Passlock
® on page 119.
If the light comes on continuously while driving
and stays on, there may be a problem with
the Passlock
® System. Your vehicle will not be
protected by Passlock ® , and you should see your
GM dealer.
