highway driving may increase the range reading).
If the range display shows
“Lo”, you should stop for fuel as soon as
possible.
Your computer needs enough data for
the “RANGE” reading to work,
however,
so it will read “Lo” for a while when your vehicle is brand new
(under
25 miles). Also, it may show “Lo” for a while if your battery has
been disconnected.

computer receives an incorrect feedback from the system, an error code will

Oil Life Indicator
This feature lets you know when to change your engine oil. It’s based
upon the engine oil temperatures and your driving patterns.
To see
the display,
press the Information
button several times until
“XXX OIL LIFE
LEFT” appears.
You’ll see
now much oil life you have left, as a percentage. So, if you see
“95 OIL LIFE LEFT,’’ for example, that means that the way you’re
driving your car,
95% of your current oil life is still left.
The Oil Life Indicator may
say to change the oil sooner than your
maintenance schedule.
This can happen if driving conditions, such as
short trips in cold weather, cause shorter oil
life. Always keep a written
record of the mileage and date
when you last changed your oil. For more
information on when to change your oil, see
the Cadillac Maintenance
Schedule Booklet.
If you see “CHANGE OIL SOON,”
it means that you have less than 10%
of your oil life left, and you should consider changing your engine oil.
If you see “CHANGE ENGINE
OIL,” it means the oil life is gone
and you should change the oil right away (certainly
within 200 more
miles
[320 km]).

If it’s been 7500 miles (12500 km) it,always says to’ change the oil.
There are two.thingslhe 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 chinge
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.

Should a low coolant condition exist and the stop “STOP ENGINE
ENGINE OVERHEATING” message is displayed, an overheat
protection mode which alternates firing groups
of four cylinders helps
prevent engine damage. This operating mode allows your vehicle
to be
driven to a safe place in an emergency. You may drive up to 50 miles (80
km). Towing a trailer in the overheat protection mode should be avoided.
NOTICE:
After driving in the “Overheated Engine Protection Operating
Mode”, to avoid engine damage allow the engine to cool befo\
re
attempting any repair.
The engine oil may be severely degraded. Change the oil and
reset the oil life indicator. (See “Engine Oil, When to Change”

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 (-18O C) or colder. If your vehicle has this option,
see “Engine Coolant Heater” in the Index.

Downloaded from www.Manualslib.com manuals search engine What to Do with Used Oil
Did you know that used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer? Don’t let used oil
stay on your skin for
very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw away clothing or
rags containing used engine oil. (See the manufacturer’s warnings about
the use and disposal of oil products.)
Used
oil can be a real threat to the environment. If you change your own
oil, be sure to drain all free-flowing oil from the filter before disposal.
Don’t ever dispose
of oil by putting it in the trash, pouring it on the
ground, into sewers, or into streams or bodies
of water. Instead, recycle it
by taking it to a place that collects used
oil. If you have a problem
properly disposing of your used oil, ask your dealer,
a service station or a
local recycling center for help.
AIR CLEANER
Refer to the Maintenance Schedule to determine when to replace the air
filter.
See “Scheduled Maintenance Services” in the Index.
See “Air Cleaner Filter Replacement” in the Index.

NOTICE:
If the air cleaner is off, a backfire can cause a damaging engine
fire. And, dirt
can easily get into your engine, which will damage
it. Always have the air cleaner in place when you’re driving.
AUTOlMATIC TMSAZE FLUID
When to Check and Change
A good time to check your automatic transaxle fluid level is when the
engine oil is changed. Refer to the Maintenance Schedule to determine
when to change your fluid. See “Scheduled Maintenance Services” in the
Index.
How to Check
Because this operation can be a little difficult, you may choose to have
this done at a Cadillac dealership Service Department.
If you do it yourself, be sure to follow all the instructions here, or you
could get a false reading on the dipstick.
