service CADILLAC SEVILLE 1998 4.G Owner's Guide

Downloaded from www.Manualslib.com manuals search engine Then here are some tips:
Make sure your vehicle is well ventilated, with a
comfortably cool interior.
Keep your eyes moving. Scan the road ahead and to
the sides. Check your rearview mirrors and your
instruments frequently.
If you get sleepy, pull off the road into a rest, service
or parking area and take a nap, get some exercise, or
both. For safety, treat drowsiness on the highway as
an emergency.
Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in flat
or rolling terrain.

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.

negative
(-) cable to
the good battery’s
negative
(-) terminal.
Don’t let the other end
of the negative (-) cable touch
anything until the next step. The other end
of the
negative
(-) cable doesn ’t go to the dead battery. It goes
to the windshield washer bottle attaching stud on the
passenger’s upper strut tower. Don’t allow the red and
black handles on the jumper cable to touch each other.

10. Attach the cable at least
from the dead battery,
but not near engine
parts that move. The
electrical connection is
just as good there, but
the chance
of sparks
getting back to the
battery is much less.
11. Now start the vehicle with the good battery and run
the engine for awhile.
12. Try to start the vehicle with the dead battery.
If it won’t start after a few tries, it probably
needs service.
13. Remove the cables in reverse order to prevent
electrical shorting. Take care that they don’t
touch each other or any other metal. Replace the
red positive
(+) remote terminal cover to its
original position.

Towing Your Vehicle
Try to have a dealer or a professional towing service tow
your vehicle. See “Roadside Service” in the Index.
If your vehicle has been changed or modified since it
was factory-new by adding aftermarket items like-fog
lamps, aero skirting or special tires and wheels, these instructions may not be correct.
Before you do anything, turn on the hazard warning flashers.
When you call, tell the towing service:
0 That your vehicle ha$ front-wheel drive.
0 The make, model and year of your vehicle.
0 Whether you can still move the shift lever.
0 If there was an accident, what was damaged.
When the towing service arrives, let the tow operator
know that this manual contains towing instructions and
illustrations. The operator may want to see them.

Downloaded from www.Manualslib.com manuals search engine A vehicle can fall from a car carrier if it isn’t
adequately secured. This can cause
a collision,
serious personal injury and vehicle damage. The
vehicle should be tightly secured with chains or
steel cables before it
is transported.
Don’t use substitutes (ropes, leather straps,
canvas webbing, etc.) that can be cut by sharp
edges underneath the towed vehicle. Always use
T-hooks inserted in the front T-hook slots or
R-hooks inserted in the rear R-hook slots. Never
use J-hooks. They will damage drivetrain and
suspension components.
NOTICE:
Don’t have your vehicle towed on the drive
wheels unless you must.
If the vehicle must be
towed on the drive wheels, be sure to follow the
speed and distance restrictions later in this
section or your transaxle will be damaged.
If
these limitations must be exceeded, then the drive
wheels have to be supported on a dolly.
The steering wheel should be clamped in a
straight-ahead position, with a clamping device
designed
for towing service. The transaxle should be in
NEUTRAL (N) and the parking brake released.

Downloaded from www.Manualslib.com manuals search engine If No Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
0 Tow a trailer.
11 you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. Dial temperature control to the highest heat setting
2. If you’re in a traffic jam, shift to NEUTRAL (N);
and open the windows, as necessary.
otherwise, shift to the highest gear while
driving
-- OVERDRIVE (0).
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about
10 minutes.
If the warning doesn’t come back on, you can
drive normally.
If the warning continues, pull over, stop,
and park your
vehicle right away.
If there’s still no sign
of steam, you can idle the engine
for two or three minutes while you’re parked, to see
if
the warning stops. But then, if you still have the
warning,
turn ofthe engine and get everyone out of the
vehicle
until it cools down. Also, see “Overheated
Engine Protection Operating Mode” listed previously in
this section.
You may decide not to lift the hood but to get service
help right away.

Downloaded from www.Manualslib.com manuals search engine If it isn’t, the coolant level should be indicated by a
CHECK COOLANT LEVEL message on the Driver
Information Center. If it is, you may have
a leak in the
radiator hoses, heater hoses, radiator, water
pump or
somewhere else
in the cooling system.
Heater and radiator hoses, and other engine
parts, can be
very hot. Don’t touch them. If you
do, you can be burned.
Don’t run the engine
if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak filed before you drive the vehicle.
NOTICE:
Engine damage if you keep running your engine
without coolant isn’t covered
by your warranty.
See “Overheated Engine Protection Operating
Mode” in the Index.
If there seems to be no leak, with the engine on, check to
see if the electric engine cooling fans are running. If the
engine is overheating, both fans should be running.
If
they aren’t, your vehicle needs service.

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.
