1997 CADILLAC SEVILLE maintenance

Downloaded from www.Manualslib.com manuals search engine Air bags are designed to inflate only once. After they
inflate, 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 air bag modules and
possibly other parts. The service nmnual for your
vehicle covers the need to replace other parts.
Your vehicle is equipped with a crash sensing and
diagnostic module, which records information about
the
air bag system. The module records information
about the readiness
of the system, when the sensors are
activated and driver‘s safety belt usage
at deployment.
Let only qualified technicians work on your air bag
system. lmproper service
can mean that your air bag
system won’t work properly. See your dealer for service.
NOTICE:
If you damage the covering for the driver’s air
bag, it may not work properly. You may have to
replace the air bag module.
Do not open or break
the air bag covering.
g YOW Air
Air bags affect how your Cadillac should be serviced.
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. Your
Cadillac dealer and the Cadiliac Service lManual have
information about servicing your vehicle and the air bag
system.
To purchase a service manual, see “Service and
Owner Publications”
in the Index.

A CAtJTICjN:
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 wires wrapped with yellow tape
or yellow connectors. They are probably part of
the air bag system. Be sure to follow proper
service procedures, and nlake
sure the person
performing work
for you is qualified to do so.
Ths air bag system does not need regular maintenance.

If the vehicle’s safety belt will fasten aqound you, you
should we 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 wili wear, so the
c
1
L-
c
extender will be long enough for you. The extender wil
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
to the regular safety belt.
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 fron?
doing its
job, have it repaired.
Torn
or frayed safety belts may not protect you in a
t
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.) 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 nay 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.

Downloaded from www.Manualslib.com manuals search engine You really should not park your vehicle, with a trailer
attached, on
a hill. If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and
the trailer can be damaged.
But if
you ever have to park your rig on a hill. here’s
how to do it:
1.
2.
3.
4.
5.
Apply your regular brakes, but do not shift into
PARK
(P).
Have someone place chocks under the trailer wheels.
When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
Reapply the regular brakes. Then shift into
PARK (P) firmly and apply your parking brake.
Release the regular brakes. 1. Apply your regular brakes and hold the pedal
down
while
you:
Start your engine;
Shift into a gear: and
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.
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, belt, 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.
