2003 CADILLAC SEVILLE engine

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-4. Poor fuel quality will
cause your engine not to run as efficiently as designed.
You may notice this as stalling after start-up, stalling
when you put the vehicle into gear, mis®ring, hesitation
on acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the
light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
your dealer can check the vehicle. Your dealer has
the proper test equipment and diagnostic tools to ®x any
mechanical or electrical problems that may have
developed.
Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the SERVICE
ENGINE SOON or CHECK ENGINE light is on or not
working properly.
Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and your vehicle
still does not pass the inspection for lack of OBD
system readiness, your GM dealer can prepare the
vehicle for inspection.

Oil Pressure Light
{CAUTION:
Do not keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches ®re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.This light tells you if there
could be a problem with
your engine oil pressure.
The light goes on when you turn your key to ON or
START. It goes off once you start your engine. That's a
check to be sure the light works. If it doesn't come
on, be sure to have it ®xed so it will be there to warn
you if something goes wrong.
When the light comes on and stays on, it means that oil
isn't ¯owing through your engine properly. You could
be low on oil and you might have some other system
problem.

DIC Warnings and Messages
These messages will appear if there is a problem
sensed in one of your vehicle's systems. Vehicles that
are ®rst sold in Canada will have a number after
each message. This number helps to identify the
problem. You must then press INFO or INFO RESET to
clear the display screen for further use. However, be
sure to take any message that appears on the display
screen seriously and remember that pressing the
INFO or INFO RESET button will only make the
message disappear, not the problem.
DIC messages can also be displayed in French,
German, Spanish and Japanese. Contact your dealer to
have the language display adjusted for your vehicle.
BATTERY NOT CHARGING ± 7:This message
will appear if the battery is not being charged. Have the
electrical system checked by your dealership at your
earliest convenience.
BATTERY SAVER ACTIVE ± 27:This message is
displayed when the vehicle has detected that the battery
voltage is dropping beyond a reasonable point. The
battery saver system will start reducing certain features
of the vehicle that you may not be able to notice. At
the point that features are disabled, this message
is displayed. It means that the vehicle is trying to save
the charge in the battery. Turn off unnecessary
accessories to allow the battery to recharge.BATTERY VOLTAGE HIGH ± 8:This message shows
that the electrical charging system is overcharging
(more than 16 volts). To avoid being stranded, have the
electrical system checked by your dealership. You
can reduce the charging overload by using the
accessories. Turn on the lamps and radio, set the
climate control on AUTO and the fan speed on HI, and
turn the rear window defogger on. You can monitor
battery voltage on the DIC by pressing the INFO button.
The normal range is 11.5 to 15.5 volts when the
engine is running.
BATTERY VOLTAGE LOW ± 6:This message will
appear when the electrical system is charging less than
10 volts or if the battery has been drained. If this
message appears immediately after starting, it is
possible that the generator can still recharge the battery.
The battery should recharge while driving but may
take a few hours to do so. Consider using an auxiliary
charger (be sure to follow the manufacturer's
instructions) to boost the battery after returning home or
to a ®nal destination. If this message appears while
driving or after starting your vehicle and stays on, have
it checked immediately to determine the cause of
this problem. To help the generator recharge the battery
quickly, you can reduce the load on the electrical
system by turning off the accessories. You can monitor
battery voltage on the DIC by pressing the INFO
button. The normal range is 11.5 to 15.5 volts.

CHANGE ENGINE OIL ± 82:This means that the life
of the engine oil has expired and it should be changed
within 200 miles. After an oil change, the Oil Life
Indicator must be reset. See
Oil Life Indicator on
page 3-77. SeeEngine Oil on page 5-13.
CHANGE TRANS FLUID ± 47:This message will
appear when it is time to change the transaxle ¯uid. See
Part A: Scheduled Maintenance Services on page 6-4for the proper ¯uid and change intervals.
CHECK BRAKE FLUID ± 37:This message will
display if the ignition is in ON to inform the driver that
the brake ¯uid level is low. Have the brake system
serviced by a technician as soon as possible. See
Brake
System Warning and Parking Brake Indicator Light on
page 3-43
.
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. See

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
Engine Oil on page 5-13.

CHECK TIRE PRESSURE ± 144:This message is
displayed when the Tire Pressure Monitor (TPM) system
detects a low or high tire pressure condition in one or
more of the road tires. By pressing the INFO button
up or down, the DIC display will show which tire or tires
do not have the correct in¯ation pressure. A ªLOW
TIREº condition exists when the tire's air pressure is
under 25 psi (172 kPa) and a ªHIGH TIREº condition
exists when the tire's air pressure is above 38 psi
(262 kPa). The system will display the air pressure, the
tire location (LF, RF, RR or LR) and if the air pressure
is low or high. The tire pressure information is available
in English or metric measurements. For example, a
driver's side front tire that is low may be shown
as: 22 PSI LF TIRE LOW.
The correct tire in¯ation pressure should be set to those
shown on the Tire Loading-Information Label, located
on the rear edge of the driver's door. For more
information regarding proper tire in¯ation, see
In¯ation -- Tire Pressure on page 5-64. If a tire is low,
you should stop as soon as possible and inspect
your tire(s) for damage. If a tire is ¯at, see
If a Tire Goes
Flat on page 5-73.Once the TPM system detects the low or high tire
pressure condition, the message CHECK TIRE
PRESSURE will be displayed whenever you start the
engine. To remove or clear the CHECK TIRE
PRESSURE message, you will need to set the tire(s) to
the proper tire pressure. See
In¯ation -- Tire Pressure
on page 5-64.
{CAUTION:
When the CHECK TIRE PRESSURE message is
displayed on the Driver Information Center and
the tire pressure is low, your vehicle's
handling capabilities will be reduced during
severe maneuvers. If you drive too fast, you
could lose control of your vehicle. You or
others could be injured. Don't drive over 55
mph (90 km/h) when the tire pressure is low.
Drive cautiously and correct the tire pressure
as soon as you can.

stay on for ®ve seconds. This message can be
customized for you by your dealer.
ENGINE COOLANT HOT, IDLE ENGINE ± 44:This
message will appear when the engine coolant
temperature is over 262ÉF (128ÉC). Stop and allow your
vehicle to idle in PARK (P) until it cools down and the
message is removed. Do not increase engine speed
above a normal idle. If it does not cool down, turn off the
engine and have it serviced before driving it again.
Severe engine damage can result from an overheated
engine. See
Engine Overheating on page 5-28.ENGINE HOT±AC OFF ± 16:This message displays
when the engine coolant becomes hotter than the normal
