CADILLAC SEVILLE 1993 4.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine Odometer
You may wonder what happens if a car has to have a new odometer
installed. The new one may read the correct mileage. This
is because your
car’s computer
has stored the mileage in memory. If it isn’t stored, then
this odometer
is set at zero, but a label on the driver’s door must show the
old reading and when the new one was installed.
WARNING LIGHTS
This section describes the warning lights that may De on your vehicle. The
pictures will help you locate them.
Warning lights can signal that something is wrong before
it becomes
serious enough
to cause an expensive repair or replacement. Paying
attention to your warning lights could also save you
or others from injury.
Warning lights go on when there may be or is a problem with one
of your
vehicle’s functions.
As you will see in the details on the next few pages,
some warning lights come on briefly when you turn the ignition key just to
let you
know they’re working. If you are familiar with this section, you
should not be alarmed when this happens.
When one
of the warning lights comes on and stays on when you are
driving, check the section that tells you what to do about it. Please follow
the manual’s advice. Waiting to do repairs can be costly
-- and even
dangerous.
So please get to know your warning lights. They’re a big help.
Your vehicle may also have a driver information system that works along
with.
. the ,. warning lights. See “Driver Information System” in the Index.

Downloaded from www.Manualslib.com manuals search engine Brake System Warning Light
Your Cadillac hydraulic brake system is divided into two parts. If one part
isn’t working, the other part can still work and stop
you. For good
braking, though, you need both parts working well.
If the warning light goes on, there could be a brake problem. Have your
brake system inspected right away.
This light should come
on as you start the
vehicle.
If it doesn’t
come
on then, have it
fixed
so it will be ready
to warn you if there’s a
problem.
This light
will also come on when you set your parking brake, and will
stay on if your parking brake doesn’t release fully. If it stays on after your
parking brake is fully released, it means you have a brake problem. If the
light comes
on while driving, pull off the road and stop carefully. You may
notice that the pedal is harder to push. Or, the pedal may go closer to the
floor. It may take longer to stop. If the light is still
on, have the vehicle
towed for service. (See “Towing Your Vehicle” in the Index.)
A CAUTION:
Your brake system may not be working properly if the brake
warning light is on. Driving with the brake warning light on can
lead to an accident. If the light
is still on after you’ve pulled off
the road and stopped carefully, have the vehicle towed for
service.

Anti-Lock Brake System Warnmg Light
With anti-lock, this light will go on when you start your engine and may
stay on for several seconds
or so. That’s normal. If the light doesn’t come
on, have it fixed
so it will be ready to warn you if there is a problem.
If the light stays on or comes on when you’re driving, stop as soon as
possible and turn the key
off. Then start the engine to reset the system. If
the light still stays
on, or comes on again while you’re driving, your
Cadillac needs service. Unless the regular brake system warning light
is
also on, you will still have brakes, but not anti-lock brakes. If the regular
brake system warning light is also on, see “Brake System Warning Light”
earlier in this part.
The anti-lock brake system warning light may also come
on when you are
driving with a compact spare tire. If this happens, the light means you
won’t have anti-lock
until you replace the compact spare with a full-size
tire. If the warning light stays on after you replace the compact spare with
;I full-six ticc, or if II corms on uguin when you’re driving, your Cadillac

This light tells you if
there could be
a
j ’ 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 just a check to be sure the light works.
If it doesn’t, be sure to have it fixed so it will be there to warn you if
something goes wrong.
When the light

your engine properly. You could be low on oil, or you might have some
other oil problem.
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

Engine Speed Limiter (Northstar)
If you have the 4.6 L Northstar engine, you have an Engine Speed
Limiter. This feature prevents the engine from operating at too many
revolutions per minute (RPM). When your engine
RPM's are critically
high the fuel supply to the engine is
shut off. When the engine speed
slows, the furl supply will come on again. This helps prevent damage to
the engine.

Your fuel gage shows about how much fuel is in your tank. It works only
when the ignition is in the “RUN” position.

If the fuel level is within approximately one gallon (3.9 liters) of being full
the letter
“F” is shown.
If the fuel
level is between 1 and 2 gallons (3.9 and 7.6 liters) from being
empty the letter
“E” is shown. If the fuel supply gets down to
approximately
1 gallon (3.9 liter) the “E” will flash, and the “ FUEL
LEVEL VERY
LOW” message will appear in the Driver Information
Center
(DIC). (On the analog fuel gage, the “FUEL LEVEL VERY

message will also appear.)
Here are a few concerns some owners have had about the

6 i
c
Your Fuel Data Panel teUs you all you want to know about your fuel economy
and how
far you can travel with the fuel remaining. Here’s how it works.
DATA: Push this button to toggle between “ INST MPG” (instantaneous
miles per gallon) or the “AVG MPG” (average mile per gallon) displays.
You can also display it in metric units by pressing the “ENG MET” button.
RESET: Push this button to reset the “ AVG MPG” to zero.
AVG MPG (Average Fuel Economy): When “ AVG MPG” is selected, the
total distance is divided by the total fuel used.
INST (Instantaneous Fuel Economy): When “ INST MPG” is selected,
you
will see what your fuel economy is at that instant. The computer
takes a new reading twice
every second. It will show economy up to 70
miles per gallon (or 2 liters per 100 Kilometers).
RANGE: This display shows how far the computer thinks you can go with
the fuel that is in your tank. The computer does not know what driving
conditions
will be like for the rest of your trip, so the range is estimated
based on your previous fuel economy. Therefore, your range reading may
change as your driving habits change (going from city to highway driving
may increase the range reading).
When you get down to
40 miles to go (or, in metric 64 km) the range
display will show
“Lo”.
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 will show “Lo” for a while if your battery has
been disconnected.
