1998 CADILLAC ELDORADO check engine

Downloaded from www.Manualslib.com manuals search engine 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,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical
or electrical
problems that may have developed.
Oil Pressure Light
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 RUN 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 fixed so it will be there to warn you if
something goes wrong. When the light
cumes on
and stays on, it means that
oil isn’t flowing through your engine properly. You
could
be low on oil and you might have some other
system problem.
1 A CAUTION:
Don’t keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You
or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
I NOTICE: 1
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

appear
if the battery is not being charged. Have the
electrical system checked by your dealership at your
earliest convenience.
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 Driver Information Center
(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 and may take a few hours to do
so. Consider using an auxiliary charger to boost the
battery after returning home or to a final destination.
(Be sure to follow the manufacturer’s instructions
when using a battery charger.)
If this message appears and stays on while driving or
after starting your vehicle, 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
Driver Information Center (DIC) by pressing the
INFO
button. The normal range is 11.5 to 15.5 volts.

the oil level is never sensed 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

you may hear a noise or feel a vibration in the brake
pedal. This is normal.
When the STABILITY

symbol
on it until AUTO is displayed on the screen.
At this setting, the fan speed is automatically controlled.
If it is cold outside, the blower may not run in the
maximum high fan speed right away. The system checks
the temperature
of the engine coolant to assure it is
warm enough to provide heat. When the engine coolant
is warm, the controller allows the fan
to gradually
increase to
a higher speed. This prevents cold air from
blowing into the passenger compartment. If
you want
the blower fan at a high speed, press the up arrow button
until
you see HI on the display. If you want the fan
speed to be automatic, but you like the fan speed to be
higher than the AUTO setting, press the fan symbol
button until HI AUTO is shown
on the display. If you
want the blower fan at
a low speed, press the down
arrow button until
LO is shown on the display. If you
want the fan speed to
run lower than the AUTO
setting, press the button until LO AUTO is shown
on the display.

off. The system will cool and dehumidify the air inside
the vehicle. In the
AUTO mode, the display will show
that
AC is active, but the air conditioning compressor
only operates when the system determines it
is needed.
RECIRCULATION: Press this button to limit the
amount
of fresh air entering your vehicle. This is helpful
when you are trying to cool the air quickly or limit odors
entering your vehicle.
In the AUTO mode, the system
will use recirculation as necessary
to cool the air.
Pressing the recirculation button will change the
operation to a manual mode and the air will recirculate
non-stop. Press this button again to turn
off the
recirculation feature.
