1997 CADILLAC CATERA service indicator

Downloaded from www.Manualslib.com manuals search engine Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag’s electrical system for malfunctions.
The light tells you if there is an electrical problem. The
system check includes the air bag sensors, the air bag
modules, the wiring and the diagnostic module. For
more information on the air bag system, see “Air Bag”
in the Index.
This light will come on for
a few seconds when you
i start your engine. Then the
light should go out. This
means the system is ready. The
air bag readiness light should come on for a few
seconds when you turn the ignition key to
RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready
to warn you if there is a problem.
Charging System Indicator Light
When you turn the key to
START, this light will
come on briefly to show
that the generator and
battery charging systems
are working.
If this light stays on, you need service and you should
take your Catera to the dealer at once.
To save the
battery until you get there, turn
off all accessories.
If the air bag readiness light stays on after you start the
engine
or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.

This warning light should
come on while you are
starting
the engine. If the
light doesn’t come on, have
4
it repaired.
Malfunction Indicator Lamp
(Check Engine Light)
Your Catera is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
CHECK
ENGINE
control systems.
Your Catera is equipped with a low coolant level sensor
(switch and float) that is designed
to detect when your
vehicle’s coolant level drops below the set limit. If the
low coolant level sensor (under the coolant surge tank)
detects that the level drops while the engine is running,
the low coolant indicator will light and remain lit until
the ignition switch is turned off. Check the coolant level and add coolant as needed. The light should turn
off as
soon as the coolant level
is at its proper operating range. This
system is called OBD
I1 (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable levels for
the life of the vehicle, helping
to produce a cleaner
environment. (In Canada,
OBD I1 is replaced by
Enhanced Diagnostics.) The CHECK
ENGINE light
comes on to indicate that there is a problem and service
is required. Malfunctions often will be indicated by the
system before any problem is apparent. This may
prevent more serious damage to your vehicle. This
system
is also designed to assist your service technician
in correctly diagnosing any malfunction.

LEVELING
This light comes on steady
when the rear load level in
your vehicle changes. This light comes on when
the brake pads on your
vehicle have significantly
worn. The pads will have to
be replaced,
so have your
vehicle serviced soon.
Do not drive your vehicle when this light is on. The rear
of your vehicle is too low and part of the body or the
rear axle may
be damaged when driving over bumpy
roads. When the light goes out, leveling is complete.
This procedure is automatic
-- you don’t have to
do anything.
If the light comes on flashing, there may be a problem
with the leveling system. You should reduce your
vehicle speed and have your vehicle serviced soon.

Downloaded from www.Manualslib.com manuals search engine If you’re using fuel rated at the recommended octane
or higher and you still hear heavy knocking, your
engine needs service. But don’t worry if you hear a little
pinging noise when you’re accelerating or driving up a
hill. That’s normal, and you don’t have to buy a higher
octane fuel to get rid of pinging. It’s the heavy, constant
knock that means you have a problem.
IT your vehicle is certified to meet California Emission
Standards (indicated on the underhood tune-up label),
it
is designed to operate on fuels that meet California
specifications.
If such fuels are not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp on
your instrument panel may turn on and/or your vehicle
may fail a smog-check test. If this occurs, return to your
authorized Catera dealer for diagnosis to determine
the
cause of failure. In the event it is determined that the
cause of the condition is the type of fuels used, repairs
may not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadlenyl manganese tricarbonyl (MMT);
ask your service station operator whether or not this fuel
contains MMT. General Motors does not recommend the
use of such gasolines. If fuels containing MMT are used, spark plug
life may be reduced and your emission
control system performance may be affected. The
malfunction indicator lamp on your instrument panel
may turn on. If this occurs, return
to your authorized
Catera dealer for service.
To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming in your engine and
fuel system, allowing your emission control system to
function properly. Therefore, you should not have to
add anything to the fuel. In addition, gasolines
containing oxygenates, such as ethers and ethanol, and
reformulated gasolines may be available in your area to
help clean the air. General Motors recommends that
you
use these gasolines if they comply with the
specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.

NOTICE:
0
0 Using the wrong fluid can badly damage
brake system parts. For example, just
a few
drops
of mineral-based oil, such as engine
oil, in your brake system can damage brake
system parts
so badly that they’ll have to be
replaced. Don’t let someone put
in the
wrong kind of
fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake
fluid
on your vehicle. If you do, wash it
off immediately. See “Appearance Care” in
the Index.
Your Catera has four-wheel disc brakes.
Your Catera has electronic wear sensors that let you
know when the front brake pads are significantly worn
and new pads are needed. The brake pad wear indicator
light will come
on and stay on when the brake pads are
worn and need
to be replaced. (See “Brake Pad Wear
Indicator Light”
in the Index.)
The brake pad wear indicator light means that
soon your brakes won’t work
well. That could
lead to
an accident. When the brake pad wear
indicator light comes on and stays on, have your
vehicle serviced.
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.

Downloaded from www.Manualslib.com manuals search engine When It’s Time for New Tires
One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will
appear when your tires have
only
1/16 inch (1.6 mm) or
less
of tread remaining.
You
need a new tire if any of the following statements
are true:
You can see the indicators at three or more places
around the tire.
You can see cord or fabric showing through the
tire’s rubber.
The tread or sidewall is cracked, cut or snagged
deep enough
to show cord or fabric.
0 The tire has a bump, bulge or split.
The tire has a puncture, cut or other damage that
can’t be repaired well because of the size or location
of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at
the Tire-Loading Information label.
The tires installed
on your vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number
on each tire’s sidewall. When you get new tires,
get ones with that same TPC Spec number. That way
your vehicle will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service on
your vehicle. If your tires have an all-season tread
design, the TPC number will be followed by an
“MS”
(for mud and snow).
If you ever replace your tires with those
not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.
