1993 CADILLAC DEVILLE maintenance

Downloaded from www.Manualslib.com manuals search engine @ Don’t attach anything to the steering wheel pad. It might
injure the driver if the air bag inflates.
The air bag is designed to inflate only once. After it inflates,
you’ll need some new parts
for your air bag system. If you
don’t get them, the air bag system won’t be there to help
protect you in another crash.
A new system will include the
air bag module and possibly other parts. The service manual
has information about the need to replace other parts.
Let only qualified technicians work on your air bag system.
Improper service can mean that your air bag system won’t
work properly. See your dealer for sewice.

Sewicing Your Cadillac with the Air Bag System
Please tell or remind anyone who works on your Cadillac that it has the c)
air bag system. There are parts of the air bag system in several places
around your vehicle.
You don’t want the system to inflate while someone
is working on your vehicle. The air bag system does not need regular
maintenance. Your Cadillac dealer and the
1993 Cadillac Service Manual
have information about the air bag system, including repair or disposal.

A CAUTION:
For up to 2 minutes after the ignition key is turned off and the
battery 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.
Be sure to follow the proper service
procedures.
When electrical work is
done under the hood or inside your vehicle, the
ignition should be in “Lock” if possible.

1. Apply your regular brakes and hold the pedal down while you:
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 for more on this. Things that are
especially important in trailer operation are automatic transaxle fluid
(don’t overfill), engine oil, axle lubricant, belts, cooling system, and brake
adjustment. Each
of these is covered in this manual, and the Index will
help you find them quickly. If you’re trailering, it’s a good idea to review
these sections before you start your trip.
Check periodically to see that all hitch nuts and bolts are tight.

Doing Your Own Service Work
If you want to do some of your own service wax, you’ll want to get the
proper Cadillac Service Manual. It tells you much more about how to
service your Cadillac than this manual can.
To order the proper service
manual, see “Service Publications” 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 Index.

A CAUTION:
You can be injured if you try to do service work on a vehicle
without knowing enough about it.
Be sure you have sufficient knowledge, experience, and 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.
FUEL
Use premium unleaded gasoline rated at 91 octane or higher. It should
meet specifications ASTM
D4814 in the US. and CGSB 3.5-92 in
Canada. These fuels should have the proper additives,
so you should not
have to add anything to the fuel.
In the
U.S. and Canada, it’s easy to be sure you get the right kind of
gasoline (unleaded). You’ll see “UNLEADED” right on the pump. And
only unleaded nozzles will fit into your vehicle’s filler neck.
Be sure the posted octane is at least 91.
If the octane is less than 91, you
may get a heavy knocking noise when you drive.
(In an emergency, you
may be able
to use lower octane -- as low as 87 -- if heavy knocking does
not occur.)
If you’re using 91 or higher octane unleaded gas and you still
get heavy knocking, your engine needs service.

When to Check and Change:
A good time to check your automatic transaxle fluid level is when the
engine oil is changed. Refer to the Maintenance Schedule to determine
when to change your fluid. See "Scheduled Maintenance Services"
in the
Index.
How to Check
Because this operation can be a little difficult, you may choose to have
this done
at a Cadillac dealership Service Department.
If you do it yourself, be sure to follow all the instructions here, or you
could get a false reading on the dipstick.
Wait at least
30 minutes before checking the transaxle fluid level if you
have been driving:
0 When outside temperatures are above 90" F (32°C).
0 At high speed for quite a while.
In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal operating
temperature, which is
180°F to 200" F (82 " C to 93 " C).
Get the vehicle warmed up by driving about 15 miles (24 km) when
outside temperatures are above
50°F (10°C). If it's colder than 50°F
(10" C), you may have to drive longer.

level must be in the cross-hatched area.

way.
Refer to the Maintenance Schedule to determine what kind
of transaxle
fluid to use.
See “Recommended Fluids and Lubricants” in the Index.
If the fluid level is low, add only enough of the proper fluid to bring the
level into the cross-hatched area on the dipstick. It doesn’t take much
fluid, generally less than a pint. Don’t overfill. We recommend you use
only fluid labeled
DEXRONWIE, because fluids with that label are
made especially for your automatic transaxle. Damage caused
by fluid
other than DEXRONWIE is not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as described under “How to
Check.”
When the correct fluid level is obtained, push the dipstick back in all
the way.
