Your Cadillac has an "Oil Life Indicator." This feature will let you know
when to change your oil
--
usually between 3,000 miles (5 000 km) and
7,500 miles (12 500
km) since your last oil change. Under severe
conditions, the indicator may come on before 3,000 miles (5 000 km).
Never drive your vehicle more than 7,500 miles (12 500 km) or 12 months
without an oil change.
The system won't detect dust in the oil.
So,
if you drive in a dusty area, be
sure to change your oil every 3,000 miles (5 000 km) or sooner if the
"CHANGE ENGINE OK' message is displayed. Remember to reset the
Oil Life Indicator when the oil has been changed. For more information,
see "Oil Life Indicator" in the Index.
How to Reset the Oil Life Indicator
r
After the oil has been changed, display the "OIL LIFE LEFT" message
by pressing the INFORMATION button. Then press and hold the
RESET button until the display shows
"loo"..
This resets thle.,oil life index.
The message will remain off until the next oil change is needed. The
percentage of oil life remaining may be checked at any time by pressing
the INFORMATION button several times until the
"OIL LE% LEFT"
message appears. For more information on the Oil Life Index feature, see
"Oil Life Index" in the Index.
Engine Coolant Heater (Engine Block Heater)
An
engine coolant heater can be a big help if you have to park outside in
very cold weather, O°F ( - 1 8 O C ) or colder. If your vehicle has this option,
see "Engine Coolant Heater" in the Index.
