The system probably will say to change the oil between 3000 miles
(5000 km) and 7500 miles (12500 km), but it may even say to change it
before 3000 under very severe conditions. It all depends on your driving
patterns. If it's been 7500 miles (12500
km)
it always says to change the oil.
There are two things the system doesn't do:
0
It can't sense heavy dust in the places where you drive. If you drive in
a dusty area, you should change your oil every 3000 miles (5000 km)
or 3 months (whichever comes first), unless the display says to change
it even sooner than that.
It doesn't check how much oil you have, so you'll still have to check
for that. To see how, see Engine Oil in the Index.
m e n You've Changed the Oil
When new oil is put in, you'll need to reset your system. To do it, display
the "OIL LIFE INDEX" by pressing the INFORMATION button. Then
press and hold the RESET buttons until the display shows "100 OIL
LIFE LEFT"
Electronic Level Control
This keeps your car level.
The ignition has to be "ON" for the level control to work. When you turn
the ignition off, you may hear the level control exhausting. The system
consists of an electronic height sensor, a small electric air compressor,
and air adjustable shock absorbers mounted on the rear of the vehicle.
If the system has a slight leak, the air compressor will run frequently for a
few seconds each time.
For a massive air leak, the air compressor will stay on for approximately
7 minutes. You should see your dealer for service, but you can keep
driving your Cadillac.
