Downloaded from www.Manualslib.com manuals search engine the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing
vehicle speed.
9 Avoiding hard accelerations.
e Avoiding steep uphill grades.
@ If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light
Is On Steady” following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine.
If the light remains on steady, see “If the Light
Is Qn Steady” following. If the light is still flashing,
follow
the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
You may
be able to correct the emission system
malfunction
by considering the following:
Did you just drive through a deep puddle
of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing
a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure
to install the fuel cap properly. It
will take a few driving trips to turn the light off.
Have you recently changed brands of fuel?
If
so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in
the Index). 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,
misfiring, 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,
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.

Downloaded from www.Manualslib.com manuals search engine I I This light tells you if there
could
be a problem with
your engine oil pressure. 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.
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 comes 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.
I NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

(INFO) button. The normal range is 1 1.5 to 15.5 volts
when the engine is running.
BATTERY VOLTS LOW - 06: 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 after driving
a few miles and the
message should
go out. 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 for a short period of time, and
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
should continue
to steer in the direction you want to go.
The system is designed
to help you in bad weather or

whatever road conditions will perrnit. If the STABILITY
ENGAGED message comes on, you’ll know that
something has caused your Cadillac to start to spin,
so
you should consider slowing down.

STABILITY REDUCED message, it means there may
be a problem with your stability enhancement system.
If you see this message, try to reset the system (stop;

Downloaded from www.Manualslib.com manuals search engine This feature lets you know when to change the engine
oil. It’s based on the engine oil temperatures and
your driving patterns.
To see the display, press the
INFORMATION
(INFO) button several times until XX
OIL LIFE LEFT appears. If you see 99% OIL LIFE
LEFT, 99 percent of your current oil life remains.
The DIC may display a CHECK OK, LEVEL message.
Always keep
a written record of the mileage and date when you changed
your oil.
For more information, see
the Cadillac Maintenance Schedule booklet. If you see
CHECK OIL LEVEL, it means that you have less than
10 percent of the 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.
The system should indicate changing the oil between
3,000 miles (5 000 km) and 7,500 miles (12 500 km).
It may indicate changing the oil before 3,000 miles
(5 000 km) depending on your driving habits. If the
vehicle has been driven
7,500 miles (12 500 km), it
will indicate to change the oil. If you drive in a dusty
area, you should change your oil every
3,000 miles
(5 000 km) or three months (whichever comes first)
unless the display indicates changing
it sooner. The
system 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.
When new oil is added, you’ll need to reset
the system.
To reset, display the Oil Life Indicator by pressing the
