flat tire CADILLAC DEVILLE 2004 8.G Owners Manual

The correct tire ination pressure should be set to those
shown on the Tire Loading-Information Label, located on
the rear edge of the driver’s door. For more information
regarding proper tire ination, seeInation - Tire
Pressure on page 5-74. If a tire is low, you should stop as
soon as possible and inspect your tire(s) for damage. If a
tire is at, seeIf a Tire Goes Flat on page 5-85.
Once the TPM system detects the low or high tire
pressure condition, the message CHECK TIRE
PRESSURE will be displayed whenever you start the
engine. To remove or clear the CHECK TIRE
PRESSURE message, you will need to set the tire(s) to
the proper tire pressure. SeeInation - Tire Pressure on
page 5-74.
{CAUTION:
When the CHECK TIRE PRESSURE message is
displayed on the Driver Information Center and
the tire pressure is low, your vehicle’s
handling capabilities will be reduced during
severe maneuvers. If you drive too fast, you
could lose control of your vehicle. You or
others could be injured. Don’t drive over 55
mph (90 km/h) when the tire pressure is low.
Drive cautiously and correct the tire pressure
as soon as you can.
CHECK WASHER FLUID – 25:This message means
that your vehicle is low on windshield washer uid.
SeeWindshield Washer Fluid on page 5-41.
DRIVER DOOR AJAR – 140:This message will
display anytime the key is in ON, the transaxle is not in

Tire Pressure Monitor Operation
The Tire Pressure Monitor (TPM) system uses radio
and sensor technology to check tire pressure levels.
Sensors, mounted on each road wheel, transmit
tire pressure readings to a receiver located in the trunk.
Tire pressure status and tire pressure warnings are
shown on the Driver Information Center (DIC) display.
SeeDriver Information Center (DIC) on page 3-62,
for details regarding DIC controls and displays.
The system operates on a radio frequency subject to
Federal Communications Commission (FCC) Rules and
with Industry and Science Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions: (1)
this device may not cause harmful interference, and (2)
this device must accept any interference received,
including interference that may cause undesired
operation.This device complies with RSS-210 of Industry and
Science Canada. Operation is subject to the following
two conditions: (1) this device may not cause
interference, and (2) this device must accept any
interference received, including interference that may
cause undesired operation of the device.
Changes or modications to this system by anyone
other than an authorized service facility could void
authorization to use this equipment.
If the TPM system detects low tire pressure, below
25 psi (172 kPa), or high tire pressure, above 38 psi
(262 kPa), a message, CHECK TIRE PRESSURE, will
appear on the Driver Information Center (DIC)
display. By pressing the INFO button, the DIC screen
will show which tire(s) has the low or high pressure
condition. SeeInation - Tire Pressure on page 5-74for
information regarding correct tire ination. If a tire is
low, you should stop as soon as possible and check all
your tires for damage. If a tire is at, seeIf a Tire
Goes Flat on page 5-85.
5-76

{CAUTION:
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.
When It Is Time for New Tires
One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of tread
remaining.
You need a new tire if any of the following statements
are true:
You can see the indicators at three or more places
around the tire.
You can see cord or fabric showing through the
tire’s rubber.
The tread or sidewall is cracked, cut or snagged
deep enough to show cord or fabric.
The tire has a bump, bulge or split.
The tire has a puncture, cut or other damage that
can’t be repaired well because of the size or
location of the damage.
5-79

If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new GM
original equipment parts. This way, you will be sure to
have the right wheel, wheel bolts and wheel nuts
for your vehicle.
{CAUTION:
Using the wrong replacement wheels, wheel
bolts or wheel nuts on your vehicle can be
dangerous. It could affect the braking and
handling of your vehicle, make your tires lose
air and make you lose control. You could have
a collision in which you or others could be
injured. Always use the correct wheel, wheel
bolts and wheel nuts for replacement.Notice:The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance and tire or tire chain
clearance to the body and chassis.
SeeChanging a Flat Tire on page 5-86for more
information.
Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You can’t know how it’s been used
or how far it’s been driven. It could fail
suddenly and cause a crash. If you have to
replace a wheel, use a new GM original
equipment wheel.

If a Tire Goes Flat
It’s unusual for a tire to “blowout” while you’re driving,
especially if you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But if you should ever have a “blowout,” here are a few
tips about what to expect and what to do:
If a front tire fails, the at tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel rmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use
in a skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop, well off the road if possible.{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without
the appropriate safety equipment and training.
The jack provided with your vehicle is
designed only for changing a at tire. If it is
used for anything else, you or others could be
badly injured or killed if the vehicle slips off
the jack. Use the jack provided with your
vehicle only for changing a at tire.
If a tire goes at, the next part shows how to use your
jacking equipment to change a at tire safely.
5-85

Changing a Flat Tire
If a tire goes at, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your
hazard warning ashers.
{CAUTION:
Changing a tire can be dangerous. The vehicle
can slip off the jack and roll over you or other
people. You and they could be badly injured or
even killed. Find a level place to change your
tire. To help prevent the vehicle from moving:
1. Put the shift lever in PARK (P).
2. Set the parking brake rmly.
3. Turn off the engine and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain in the
vehicle.
To be even more certain the vehicle won’t
move, you can put blocks at the front and rear
of the tire farthest away from the one being
changed. That would be the tire on the other
side, at the opposite end of the vehicle.The following steps will tell you how to use the jack and
change a tire.

Removing the Flat Tire and Installing
the Spare Tire
1. Using the wheel wrench, loosen all the wheel nuts.
Do not remove them yet.
5-89

Storing the Flat Tire and Tools
{CAUTION:
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 have put the compact spare tire on your
vehicle, you will need to store the at tire in your trunk.
Store the at tire as far forward in the trunk as
possible. Store the jack and wheel wrench in their
compartment in the trunk. For storage, the jack must be
raised until the screw end is ush with the edge of
the jack.
Storing the Spare Tire and Tools
{CAUTION:
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.
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 for
information on how to properly position and store the
compact spare tire.
