engine CADILLAC DEVILLE 1998 7.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine NOTICE:
Improperly tightened wheel nuts can lead to
brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque specification.
Don’t try to put a wheel cover on your compact spare
tire. It won’t fit. Store the wheel cover in the trunk
until you have the flat tire repaired
or replaced.
I NOTICE:
Wheel covers won’t fit on your compact spare. If
you try to put a wheel cover on your compact
spare, you could damage the cover or the spare.
Storing the Flat Tire and Tools
L
Storing a jack, a tire or other equipment in the
passenger compartment
of the vehicle could
cause injury. In a sudden stop
or collision, loose
equipment could strike someone. Store all these
in the proper place.
After you’ve put the compact spare tire on your vehicle,
you’ll need to store the flat tire in your
trunk. Use the
following procedure
to secure the flat tire in the trunk.
Put the flat tire in the trunk
so the side that faces out
when
it is on the vehicle is facing down. The full-size
tire will not
fit down into the well. Place it so the front
is in the well and the rear is out of the well.

the compact spare tire with a full-size tire as soon as you
can. See the storage instructions label to replace your
compact spare into your trunk properly.
I RETAINER --
Compact Spare Tire
Although the compact spare tire was fully inflated
when your vehicle was new, it can
lose air after a time.
Check the inflation pressure regularly. It should be
60 psi (420 Wa).
After installing the compact spare on your vehicle,
you should stop as soon as possible and make sure
your spare tire is correctly inflated. The compact spare is made to perform well at speeds up to
65 mph
(105 km/h) for distances up to 3,000 miles (5 000 km),
so you can finish your trip and have your full-size tire
repaired or replaced where you want. Of course, it’s best
to replace your spare with a full-size tire
as soon as you
can. Your
spare will last longer and be in good shape in
case you need it again.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
When the compact spare is installed, don’t take
your vehicle through an automatic car wash with
guide rails.
The compact spare can get caught on
the rails. That can damage the tire and wheel,
and maybe other parts
of your vehicle.
Don’t use your compact spare on other vehicles.
And don’t
mix your compact spare tire or wheel with
other wheels or tires. They won’t fit. Keep your spare
tire and its wheel together.
I NOTICE:
Tire chains won’t fit your compact spare. Using
them can damage your vehicle and can damage
the chains too. Don’t
use tire chains on your
compact spare.
If You’re Stuck: In Sand, Mud,
Ice or Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels too fast. The method known as
“rocking” can help you get out when you’re stuck, but
you must use caution.
1
If you let your tires spin at high speed, they can
explode,
and you or others could be injured. And,
the transaxle or other parts
of the vehicle can
overheat. That could cause an engine
compartment fire or other damage. When you’re
stuck, spin the wheels as little
as possible. Don’t
spin the wheels above
35 mph (55 km/h) as shown
on the speedometer.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
Spinning your wheels can destroy parts of your
vehicle as well as the tires. If you spin the wheels
too fast while shifting your transaxle back and
forth, you can destroy your transaxle.
For information about using tire chains on your vehicle,
see “Tire Chains” in the Index.
Rocking Your Vehicle To Get It Out
First, turn your steering wheel left and right. That will
clear the area around your front wheels.
You should
turn your traction control system
off. (See “Traction
Control System” in the Index.) Then shift back and forth
between
REVERSE (R) and a forward gear, spinning the
wheels as little as possible. Release the accelerator pedal
while you shift, and press lightly on the accelerator
pedal when the transaxle is in gear. If that doesn’t get
you out after a few tries, you may need to be towed out.
If you do need to be towed out, see “Towing Your
Vehicle” 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 Vshicle” 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.

Downloaded from www.Manualslib.com manuals search engine 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.
0 Be sure you have suffkient 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.
Fuel
Use premium udeaded 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 1,east 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 bqd enough, it can damage
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
