maintenance CADILLAC SEVILLE 1998 4.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine NOTICE:
If you damage the covering for the driver’s or the
right front passenger’s
air bag, or the air bag
covering on the driver’s and right front
passenger’s seatback, the bag may not work
properly. You may have to replace the air bag
module in the steering wheel, both the air bag
module and the instrument panel for the right
front passenger’s air bag, or both the air bag
module and seatback for the driver’s and right
front passenger’s side impact air bag.
Do not
open
or break the air bag coverings.
Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts
of the air bag systems in several places
around your vehicle. Your dealer and the Seville Service
Manual have information about servicing your vehicle
and the air bag systems.
To purchase a service manual,
see “Service and Owner Publications” in the Index.
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate during improper service. You
can be injured if you are
close to an air bag when
it inflates. Avoid yellow connectors. They are
probably part of the air bag systems. Be sure
to
follow proper service procedures, and make sure
the person performing work for you is qualified
to do
so.
The air bag systems do not need regular maintenance.
Rear Seat Passengers
It’s very important for rear seat passengers to buckle up!
Accident statistics show that unbelted people in the rear
seat are hurt more often in crashes than those who are
wearing safety belts.
Rear passengers who aren’t safety belted can be thrown
out
of the vehicle in a crash. And they can strike others
in the vehicle who are wearing safety belts.

Downloaded from www.Manualslib.com manuals search engine Safety Belt Extender
If the vehicle’s safety belt will fasten around you, you
should use it.
But if a safety belt isn’t long enough to fasten, your
dealer will order you an extender. It’s free. When you go
in to order it, take the heaviest coat you will wear,
so the
extender will be long enough for you. The extender will
be just for you, and just for the seat in your vehicle that
you choose. Don’t let someone else
use it, and use it
only for the seat it is made to fit. To wear it, just attach it
to the regular safety belt.
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and
all your belts, buckles, latch plates, retractors and
anchorages are working properly.
Look for any other
loose or damaged safety belt system parts.
If you see
anything that might keep a safety belt system from
doing its job, have
it repaired.
Tom or frayed safety belts may not protect you in a
crash. They
can rip apart under impact forces. If a belt is
torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)
Replacing Restraint System Parts
After a Crash
If you’ve had a crash, do you need new belts?
After a very minor collision, nothing may be necessary.
But if the belts were stretched, as they would be if worn
during a more severe crash, then you need new belts.
If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have safety belt
or seat parts repaired or replaced. New
parts and repairs
may be necessary even
if the belt wasn’t being used at
the time of the collision.
If an air bag inflates, you’ll need to replace air bag
system parts. See the part on the air bag system earlier in
this section.
If the frontal air bags inflate, you’ll also need to replace
the driver’s and right front passenger’s safety belt
buckle assembly. Be sure to do
so. Then the new buckle
assembly will be there to help protect you in a collision.

Driver Information Center Messages
These messages will appear if there is a problem sensed
in one of your vehicle’s systems. Vehicles that
are first
sold in Canada will have a number after each message.
This number helps to identify the message which is only
displayed in English.
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 is used to convey that the vehicle is trying
to save the charge in the battery. Turn
off unnecessary
accessories to allow the battery to recharge.
ENGMET: Press this button to display information in
the English (miles) or metric (kilometers) system.

Downloaded from www.Manualslib.com manuals search engine 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

You can monitor battery voltage on the DIC by pressing
the
INFiO 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
9 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 final 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 BRAKE PADS - 125: This message is used
to notify you that the brake pads may have worn down.
A sensor is connected to the brake pads and is triggered
when they wear to a certain point. Have the front and
rear brakes serviced by your dealer as soon as possible.
CHANGE TRANS FLUID - 47: This message will
appear when
it is time to replace the transaxle fluid. See
the Maintenance Schedule booklet for the proper fluid and change intervals.
CHECK BRAKE FLUID - 37: This message will
display if the ignition is in
ON to inform the driver that
the brake fluid level is low. Have the brake system
serviced by a technician as soon as possible. See “Brake
System Warning Light” in the Index.
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.
CHANGE ENGINE OIL - 82: This means that the life
of the engine oil has expired and it should be changed
within
200 miles. See “Engine Oil” and “Filter
Recommendations” in the Maintenance Schedule
booklet. After
an oil change, the Oil Life Indicator must
be reset. See “Oil Life Indicator” in the Index
on how to
reset
it.

Downloaded from www.Manualslib.com manuals search engine Oil Life Indicator
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 INFO
button several times until ENGINE OIL LIFE appears.
If you see 99% ENGINE OIL LIFE, 99 percent of your
current oil life remains.
The DIC may display a CHANGE ENGINE OIL
message. Always keep a written record of the mileage
and date when
you changed your oil. For more
information, see the Maintenance Schedule booklet. If
you see CHANGE ENGINE OIL, it means the oil life
is
gone and you should change the oil right away. 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. 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.
When the oil is changed, you'll need to reset the system.
To reset, display the Oil Life Indicator by pressing the
INFO button. Then press and hold the INFO RESET
button until the display shows
100% ENGINE
OIL LIFE.

0 Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of the windows.
of objects. This helps circulate air throughout
your vehicle.
0 Keep the air path under the front seats clear
Passenger Compartment Air Filter
Passenger compartment air, both outside air and
recirculated air, is routed through
a passenger
compartment filter, which is part of
a three-piece filter
system. The filter removes certain contaminants from
the air, including pollen and dust particles. Reductions
in airflow, which
may occur more quickly in dusty
areas, indicate that the filter needs to be replaced early. The
carbon-treated filter is located inside the air
control module, with an access panel underneath the
instrument panel near the accelerator pedal. The
filter should be replaced as part of routine scheduled
maintenance. See the Maintenance Schedule booklet
for replacement intervals. See your dealer for details
on changing the filter.
Your vehicle will not be damaged if
you choose not to
replace the filter once the old one is removed. However,
the air will no longer be filtered.

Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
0 Start your engine;
0 Shift into a gear; and
0 Be sure the parking brake has released.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule booklet
for more on this. Things that are especially important
in trailer operation are automatic transaxle fluid (don’t
overfill), engine oil, drive belt, cooling system and
brake adjustment.
If you’re trailering, it’s a good idea to
review this information before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See “Engine Overheating’’
in the Index.

Doing Your Own Service Work
If you want to do some of your own service work, you’ll
want to use the proper Cadillac Service Manual. It tells
you much more about how to service your vehicle than
this manual can.
To order the proper service manual, see
“Service and Owner Publications” in the Index.
Your vehicle has an air bag system. Before attempting to
do your own service work, see “Servicing Your Air
Bag-Equipped Vehicle” in the Index.
You should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform. See “Maintenance Record” in the Maintenance
Schedule Booklet.

You can be injured and your vehicle could be
damaged if you
try to do service work on a
vehicle without knowing enough about it.
Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. “English” and “metric”
fasteners can be easily confused. If you use
the wrong fasteners, parts can later break
or fall off. You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your dealer before adding equipment to the outside of
your vehicle. Use premium unleaded gasoline rated at
91 octane or
higher for best performance. You may
use middle grade
or regular unleaded gasolines, but your vehicle may not
accelerate as well.
At
a minimum, the gasoline you use should meet
specifications
ASTM D4814 in the United States and
CGSB 3.5-M93 in Canada. Improved gasoline
specifications have been developed by the American
Automobile Manufacturers Association
(AAMA) for
better vehicle performance and engine protection.
Gasolines meeting the AAMA specification could
provide improved driveability and emission control
system protection compared
to other gasolines.
Be sure the posted octane for premium is at least 91 (at
least
89 for middle grade and 87 for regular). If the octane
is less than 87, you may get a heavy knocking noise when
you
drive. If it’s bad enough, it can darnage your engine.
If you’re using fuel rated at the recommended octane or
higher and you 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.
