2007 CADILLAC STS Owners Manual

{CAUTION:
Raising your vehicle with the jack
improperly positioned can damage the
vehicle and even make the vehicle fall. To
help avoid personal injury and vehicle
damage, be sure to place the jack in the
proper location before raising the vehicle.
If you ever use a jack to lift your vehicle, follow
the instructions that came with the jack, and
be sure to use the correct lifting points to avoid
damaging your vehicle.Notice:Lifting your vehicle improperly can
damage your vehicle and result in costly repairs
not covered by your warranty. To lift your
vehicle properly, follow the advice in this part.
To help prevent vehicle damage:
Be sure the jack you are using meets the
weight standards for your vehicle and is
in good working order.
Be sure to place a block or pad between
the jack and the vehicle.
Make sure the jack you are using only
contacts the jacking location lift points and
is not leaning on any other vehicle
components such as the rocker panels, the
oor pan, or the stone guard moldings.
Lift only in the areas shown in the following
pictures.
449

Lifting From the Front
The front lifting points can be accessed from
either side of your vehicle, behind the front tires.
1. Locate the front lifting points using the
diagram above. The front lifting location
is about 15 inches (37 cm) from the rear edge
of the front wheel well.
2. Be sure to place a block or pad between the
jack and the vehicle.
3. Lift the vehicle with the jack, making sure the
jack is centered on the front lifting point.
Lifting From the Rear
The rear lifting points can be accessed from either
side of your vehicle, in front of the rear tires.
1. Locate the rear lifting points using the
diagram above. The rear lifting location
is about 7 inches (17 cm) from the front edge
of the rear wheel well.
2. Be sure to place a block or pad between the
jack and the vehicle.
3. Lift the vehicle with the jack, making sure the
jack is centered on the rear lifting point.

If a Tire Goes Flat
It is unusual for a tire to blowout while you are
driving, especially if you maintain your tires
properly. SeeTires on page 421. If air goes out of
a tire, It is 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 would 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.If a tire goes at, and your vehicle has a compact
spare tire, seeChanging a Flat Tire on page 464.
This information shows you how to use your
vehicle’s tire changing equipment and how
to change a at tire safely.
{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 your vehicle has 255/45ZR18 size tires, there is
no spare tire, jack, or tire changing equipment.
A tire inator kit, included with your vehicle, may
be used to seal small punctures in the tread
area of the tire. SeeTire Inator Kit on page 452.
451

Run-Flat Tires (STS-V)
If your vehicle has run-at tires, there is no spare
tire and no tire changing equipment. Run-at
tires can operate effectively with no air pressure
for a limited distance and speed. These tires
perform so well without any air pressure that a Tire
Pressure Monitor (TPM) is used to alert you
when there is a low tire condition.
{CAUTION:
When the low tire warning light is
displayed on the instrument panel cluster,
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. Do not drive over 55 mph
(90 km/h) when the low tire warning light
is displayed. Drive cautiously and check
your tire pressures as soon as you can.SeeRun-Flat Tires (STS-V) on page 429andTire
Pressure Monitor System on page 433, for
additional information.
{CAUTION:
Special tools and procedures are required
to service a run-at tire. If these special
tools and procedures are not used you or
others could be injured and your vehicle
could be damaged. Always be sure the
proper tools and procedures, as described
in the service manual, are used.
To order a service manual seeService
Publications Ordering Information on page 543.
Tire Inator Kit
Your vehicle has a tire inator kit. There is no jack
or spare tire. The kit uses a liquid tire sealant
and air at the same time to seal small punctures
in the tread area of the tire. Be sure to read
and follow all of the tire inator kit instructions.
452

The kit includes the following:
A. Air Compressor
B. Tire Sealant Canister
C. Air Compressor
Accessory Plug
D. On/Off SwitchE. Air Pressure Gage
F. Air Compressor
Inator Hose
G. Sealant
Filling HoseIf the at tire is due to a slow leak caused by a nail
or other similar road hazard, the tire inator kit may
be used to temporarily repair the damaged tire.
After temporarily repairing the tire inator kit,
it is recommended to take your vehicle to
an authorized GM dealer within 100 miles
(161 kilometers) of driving to have the tire
inspected and repaired. If the sealant is
not removed from the tire within 100 miles
(161 kilometers) of driving, it is more likely that the
tire may get damaged and have to be replaced.
453

Accessing the Tire Inator Kit
To access the tire inator kit, do the following:
1. Open the trunk. SeeTrunk on page 101
for more information.
2. Locate the tire inator kit on the driver’s side of
the vehicle, near the back corner of the trunk.3. Remove the tire
inator kit strap
by squeezing the
two tabs of the quick
release buckle.
4. Remove the inator kit from its foam container.
454

Tire Sealant
The kit contains a liquid sealant that when injected
into a at tire, may temporarily repair nail holes
or cuts in the tread area of the tire. The tire sealant
cannot repair tire damage caused while driving
on a at tire or a tire that has had a “blow out” or
a tire that has punctures in the sidewall areas.
The tire sealant solution is to be used for a single
tire and can only be used once.
Check the tire sealant expiration date on the
sealant canister. The sealant may not be
as effective beyond the expiration date. If needed,
see your GM dealer for a replacement canister.
Using the Tire Inator Kit
To use the tire inator kit, do the following:
1. Place the inator kit on the ground and unwrap
the sealant lling hose from the compressor.
2. Remove the air compressor accessory plug
from the unit. To do this, pull the top portion
of the wrapped cord out rst, then the bottom,
and then unsnap the plug. Do not insert the
plug into an accessory outlet yet.
3. Remove the valve stem cap from the at tire
by turning it counterclockwise.
If an object, such as a nail, has penetrated
the tire, do not remove it.
455

4. Attach the sealant lling hose (A) onto the tire
valve stem. Turn it clockwise until it is tight.
Make sure the inator kit on/off switch (B) is in
the O (off) position.5. Plug the air compressor accessory plug (C)
into an accessory power outlet in the vehicle.
SeeAccessory Power Outlet(s) on page 228
for 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.
