tire pressure CADILLAC DEVILLE 1998 7.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine The anti-lock system can change the brake pressure faster
than any driver could. The computer is programmed to
make the most of available tire and road conditions.
Here’s how anti-lock works. Let’s say the road is wet.
You’re driving safely. Suddenly an animal jumps out
in
front of you.
You slam on the brakes. Here’s what happens with
ABS.
A computer senses that wheels are slowing down. If one
of the wheels is about to stop rolling, the computer will
separately work the brakes at each front wheel and at
both rear wheels. You
can steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.

Downloaded from www.Manualslib.com manuals search engine Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the water.
This can happen
if the road is wet enough and you’re
going fast enough. When your vehicle is hydroplaning,
it has little or no contact with the road.
Hydroplaning doesn’t happen often. But it can if your
tires do not have much tread or
if the pressure in one or
more is low. It can happen
if a lot of water is standing on
the road. If you can see reflections from trees, telephone
poles or other vehicles, and raindrops “dimple” the
water’s surface, there could be hydroplaning.
Driving Through Deep Standing Water
NOTICE:
If you drive too quickly through deep puddles or
standing water, water can come in through your
engine’s air intake and badly damage your
engine. Never drive through water that is slightly
lower than the underbody
of your vehicle. If you
can’t avoid deep puddles or standing water, drive through them veryslowly.
Hydroplaning usually happens at higher speeds. There
just isn’t a hard and fast rule about hydroplaning. The
best advice is to slow down when it is raining.
Some Other Rainy Weather Tips
0 Besides slowing down, allow some extra following
distance. And be especially careful when you pass
another vehicle. Allow yourself more clear room ahead, and be prepared to have your view restricted
by road spray.
0 Have good tires with proper tread depth. (See “Tires” in the Index.)

Downloaded from www.Manualslib.com manuals search engine The exit speed is usually posted.
Here are some things you can check before a trip:
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re not fresh
-- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready to go.
If it needs
service, have
it done before starting out. Of course,
you’ll find experienced and able service experts in
Cadillac dealerships all across North America. They’ll
be ready and willing to help if you need it.

Downloaded from www.Manualslib.com manuals search engine Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.
Then, shut the engine
off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or
so until help comes.

Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading Information label
found
on the driver's door tells you the proper size,
speed rating and recommended inflation pressures for
the tires on your vehicle. It also gives you important
information about the number of people that can be in
your vehicle and the total weight that you can carry.
This weight is called the Vehicle Capacity Weight and
includes the weight
of all occupants, cargo and all
options not installed
in the factory.

Downloaded from www.Manualslib.com manuals search engine The compact spare is for temporary use only. Replace
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 Tires
Your ~ew vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where ,to obtain service, see
your-Cadillac Warranty booklet for details.
I-
A CAUTION:
L
Poorly maintained and improperly used tires
are dangerous.
Overloading your tires can cause
overheating as
a result of too much friction.
You could have an air-out and a serious
accident. See “Loading Your Vehicle” in the Index.
‘0 Underinflated tires pose the same danger as
overloaded tires. The resultihg accident
could cause serious injury. Check all tires
frequently to maintain the recommended’
pressure. Tire pressure should be checked when
your tires are cold.
CAUTION: (Continued) CAUTION:
(Continued)
0 Overinflated tires are more likely to be
cut, punctured or broken by
a sudden
impact
-- such las when you hit a pothole.
Keep tires at the recommended pressure.
0 Worn, old tires can cause accidents. If your
tread is badly worn, or
if your tires have
been damaged, replace them.
See “Inflation
-- Tire Pressure’’ in this section
for .inflation pressure adjustment for higher
speed driving.
Inflation -- Tire Pressure
The Tire-Loading Information label, which is located on
the rear edge of the driver’s door, shows the correct
inflatiop pressures for your tires when they’re cold.
“Cold” means your vehicle has been sitting for, at least.
three’ hours or driven no more than
1 mile (1.6 km).

If you’ll be driving at high speeds (e.g., speeds of 100 mph
(160 km/h) or higher), where it is legal, set the cold
inflation pressure to the maximum inflation pressure shown on the
tire sidewall, or to 38 psi (265 kpa),
whichever is lower. See the example below. When you end
this high-speed driving, return to the cold inflation
pressure shown on the Tire-Loading Information label.
Example:
You’ll find maximum load and inflation pressure molded
on the tire’s sidewall, in small letters, near the
rim flange. It will read something like this: Maximum load 690
kg (1521 lbs.) @ 300 Wa (44 psi) Max. Press.
For this example,
you would set the inflation pressure
for high-speed driving at
39 psi (265 kPa).
NOTICE:
Don’t let anyone tell you that underinflation or
overinflation is all right.
It’s not. If your tires
don’t have enough air (underinflation), you can
get the following:
Too much flexing
0 Too much heat
0 Tire overloading
NOTICE: (Continued)
NOTICE: (Continued)
Bad wear
Bad handling
0 Bad fuel economy.
If your tires have too much air (overinflation),
you can get the following:
0 Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure.
You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks
by keeping out dirt and moisture.

Downloaded from www.Manualslib.com manuals search engine Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 rriiles
(10 000 to 13 000 krn). Any time you notice unusual
. wear, rotate your tires as soon as possible and check
wheel alignment.
Also check for damaged tires or
wheels. See “When It’s Time for New Tires” and
“Wheel Replacement” later
in this section for
more information.
The purpose of regular rotation
is to achieve more
uniform wear for
all tires on the vehicle. The first
rotation
is the most important. See “Scheduled
Maintenance Services” in the Maintenance Schedule
booklet for scheduled rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here. Don’t include the compact spare tire
in your
tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire-Loading
Information label. Make certain that
all wheel nuts
are properly tightened. See “Wheel Nut Torqoe” in
the Index.

Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after a time. The wheel could come
off and cause
an accident. When you change
a wheel, remove
any rust
or dirt from places where the wheel
attaches to the vehicle.
In an emergency, you can
use
a cloth or a paper towel to do this; but be
sure to use a scraper or wire brush later,
if you
need to, to get all the rust or dirt
off. (See ’ .
“Changing a Flat Tire” in the Index.)
