engine CADILLAC STS 2007 1.G Owners Manual

9. Inate the tire up to the recommended
ination pressure, found on the Tire and
Loading Information label located on
the vehicle’s center pillar (B-pillar) below the
vehicle’s door latch, using the air pressure
gage on the top of the unit.
The pressure gage reading is slightly high
while the compressor is on. Turn the
compressor off to get an accurate pressure
reading.
Notice:If the recommended pressure cannot
be reached after 15 minutes, the vehicle
should not be driven farther. Damage to the
tire is severe and the sealant will not be
effective. Remove the air compressor plug
from the accessory power outlet and unscrew
the inating hose from the tire valve. See
Roadside Service on page 531.
10. Move the inator kit switch to the O (off)
position once the correct tire pressure is
obtained.11. Turn off the engine.
12. Unplug the air compressor accessory plug
from the accessory power outlet in the
vehicle.
13. Disconnect the sealant lling hose from the
tire valve stem, by turning it counterclockwise,
and replace the tire valve stem cap.
Be careful when handling the tire inator
components as they may be hot after usage.
14. Wrap the sealant lling hose around the air
compressor channel to stow it in its original
location.
15. Stow the air compressor accessory plug back
in the air compressor. To do this, wrap the air
compressor accessory plug, snap in the
plug, and then push in the bottom and then
the top of the wrapped air compressor
accessory plug.

4. Push the air compressor inator hose onto the
tire valve stem and push the lever down to
secure in place.
5. Plug the air compressor accessory plug into
an accessory power outlet in the vehicle. See
Accessory Power Outlet(s) on page 228for
more information.
{CAUTION:
Idling the engine in a closed-in place or
with the climate control system off can
cause deadly carbon monoxide (CO). See
Engine Exhaust on page 125.
6. Start the vehicle. SeeStarting the Engine on
page 113for more information. The vehicle
must be running while using the air
compressor.
{CAUTION:
Inating something too much can make it
explode, and you or others could be
injured. Be sure to read the inator
instructions, and inate the tire to its
recommended pressure. Do not exceed
36 psi (248 kPa).
7. Move the inator kit switch to the I (on)
position.
8. Make sure there is a proper connection
between the tire valve stem and the air
compressor hose by looking at the air
pressure gage. If there is not a pressure
reading while the compressor is running, the
connection between the inator kit and
the tire is bad.
Check the attachment between the air
compressor hose and the tire valve stem.

Changing a Flat Tire
If you have an STS-V model, there is no spare tire
and no tire changing equipment. Your vehicle is
equipped with run-at tires. SeeRun-Flat
Tires (STS-V) on page 429for more information. If
you have an STS model, your vehicle may be
equipped with a tire inator kit. SeeTire Inator Kit
on page 452for more information. If your vehicle
is not equipped with a tire inator kit, follow
the directions for changing a at tire in this section.
If a tire goes at, avoid further tire and wheel
damage by driving slowly to a level place. Turn on
your vehicle’s hazard warning ashers. See
Hazard Warning Flashers on page 180for more
information.{CAUTION:
Changing a tire can be dangerous. The
vehicle can slip off the jack and roll over
or fall on 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. Set the parking brake rmly.
2. Put the shift lever in PARK (P).
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 will
not move, you should 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.

Vehicle Identication
Vehicle Identication Number (VIN)
This is the legal identier for your vehicle. It
appears on a plate in the front corner of the
instrument panel, on the driver side. You can see
it if you look through the windshield from outside
your vehicle. The VIN also appears on the Vehicle
Certication and Service Parts labels and the
certicates of title and registration.
Engine Identication
The eighth character in the VIN is the engine
code. This code helps you identify your vehicle’s
engine, specications, and replacement parts.
Service Parts Identication Label
This label is on your spare tire cover. It is
very helpful if you ever need to order parts. The
label has the following information:
Vehicle Identication Number (VIN)
Model designation
Paint information
Production options and special equipment
Do not remove this label from the vehicle.

Power Windows and Other Power
Options
Circuit breakers protect the power windows and
power seats. When the current load is too
heavy, the circuit breaker opens and closes,
protecting the circuit until the problem is xed or
goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected
from short circuits by a combination of fuses,
circuit breakers and fusible thermal links.
This greatly reduces the chance of res caused by
electrical problems.Look at the silver-colored band inside the fuse. If
the band is broken or melted, replace the fuse.
Be sure you replace a bad fuse with a new one of
the identical size and rating. If a fuse should
blow, see your dealer for service immediately.
If you ever have a problem on the road
and don’t have a spare fuse, you can borrow
one that has the same amperage. Just pick some
feature of your vehicle that you can get along
without – like the radio or cigarette lighter – and
use its fuse, if it is the correct amperage. Replace
it as soon as you can.
The fuses are located in three fuse blocks.
One is located in the engine compartment, on the
passenger’s side of the vehicle, and the other
two are located under the rear seat on both the
driver’s and passenger’s side of the vehicle.
487

The underhood fuse block is located in the front of
the engine compartment on the passenger’s
side of the vehicle. SeeEngine Compartment
Overview on page 373for more information
on location and removal procedure for the front
compartment underhood sights shields.
To access the fuses, push in the tabs located on
each side of the fuse block cover, then lift the
cover off.
