service interval CADILLAC DEVILLE 2002 8.G Owners Manual

2-104
CHANGE ENGINE OIL - 82: This means that the life
of the engine oil has expired and it should be changed
within 200 miles. See ªEngine Oilº and ªFilter
Recommendationsº in the Index. After an oil change,
the Oil Life Indicator must be reset. See ªOil Life
Indicator, How to Resetº in the Index.
CHANGE TRANS FLUID
- 47: This message will
appear when it is time to replace the transaxle fluid. See
ªMaintenance Scheduleº in the Index for the proper
fluid and change intervals.
CHECK BRAKE FLUID
- 37: This message will
display if the ignition is in ON to inform the driver that
the brake fluid level is low. Have the brake system
serviced by a technician as soon as possible. See ªBrake
System Warning Lightº in the Index.
CHECK COOLANT LEVEL
- 2: This message
will appear when there is a low level of engine coolant.
Have the cooling system serviced by a technician as
soon as possible.CHECK FUEL GAGE
- 50: (Analog Cluster Only)
This message will appear when the fuel supply is less
than 5 gallons (18.9 L) and the display is turned off.
A single chime will also sound when this message
is displayed.
CHECK GAS CAP
- 61: This message will appear if
the gas cap has not been fully tightened. You should
recheck your gas cap to ensure that it's on properly.
CHECK OIL LEVEL
- 36: For correct operation of
the low oil sensing system, your vehicle should be on a
level surface. A false CHECK OIL LEVEL message
may appear if the vehicle is parked on a grade. The oil
level sensing system does not check for actual oil level
if the engine has been off for a short period of time, and
the oil level is never checked while the engine is
running. If the CHECK OIL LEVEL message appears,
and your vehicle has been parked on level ground with
the engine off for at least 30 minutes, the oil level
should be checked by observing the oil dipstick. Prior to
checking the oil level, be sure the engine has been off
for a few minutes and your vehicle is on a level surface.
Then check the dipstick and add oil if necessary.
See ªEngine Oilº in the Index.

6-52 Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See ªWhen It's Time for New Tiresº and
ªWheel Replacementº later in this section for
more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See ªScheduled
Maintenance Servicesº in the Index for scheduled
rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here.Don't include the compact spare tire in your
tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire
-Loading
Information label. Vehicles equipped with the Tire
Pressure Monitor (TPM) system will need to have the
sensors reset after a tire rotation is performed. A special
tool is needed to reset the sensor identification codes.
See your dealer for service. Make certain that all wheel
nuts are properly tightened. See ªWheel Nut Torqueº
in the Index.
CAUTION:
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after a time. The wheel could come off and cause
an accident. When you change a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this; but be
sure to use a scraper or wire brush later, if you
need to, to get all the rust or dirt off. See
ªChanging a Flat Tireº in the Index.
