The oil level monitoring system only checks oil level
during the brief period between when the key is on and
the engine is cranking. It does not monitor engine oil
level when the engine is running. Additionally, an oil
level check is only performed if the engine has been
turned off for a considerable period of time allowing the
oil normally in circulation to drain back into the oil pan.
Change Oil Light
The CHANGE OIL light
should come on briefly
as a bulb check when you
start the engine. If the
light doesn’t come on,
have it serviced.
If the CHANGE OIL light comes on and stays on after
you start the engine, have the oil changed.
For additional information, see “Engine Oil, When to
Change” in the Index. To reset the oil life monitor,
see “Engine Oil Life Monitor” in the Index.
Security Light
This light will come on
when you turn the key to
ON and will stay on until
the vehicle starts.
If you’re driving and the security light comes on and
remains on, your Passlock
R
system is not working
properly. Your vehicle is not protected by Passlock and
you should see your dealer.
Cruise Light (If Equipped)
The CRUISE light comes
on whenever you set your
cruise control.
