CADILLAC CTS 2007 1.G Owners Manual

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 shown above and corresponding
triangular-shaped hoisting notches located in
the plastic molding. The rear lifting location
is about 7 inches (17.8 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 392. 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’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.If a tire goes at, and your vehicle has a spare
tire, seeChanging a Flat Tire (CTS Only) on
page 424. 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.
422

Run-Flat Tires (CTS-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. Your vehicle also
has a Tire Pressure Monitor (TPM) which will
alert you if there is a loss of tire pressure in any of
the tires. 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)
CAUTION: (Continued)
CAUTION: (Continued)
when the low tire warning light is
displayed. Drive cautiously and check
your tire pressures as soon as you can.
SeeRun-Flat Tires (CTS-V) on page 400and
Tire Pressure Monitor System on page 405,
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 501.
423

Changing a Flat Tire (CTS Only)
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
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 an automatic transmission shift
lever in PARK (P), or shift a manual
transmission to FIRST (1) or
REVERSE (R).
3. Turn off the engine and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain in
the vehicle.
CAUTION: (Continued)
CAUTION: (Continued)
Put the wheel 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.
When you have a at tire, use the following
example as a guide to assist you in the placement
of wheel blocks.
The following information will tell you next how to
use the jack and change a tire.
424

Removing the Spare Tire and Tools
(CTS Only)
The equipment you will need is in the trunk.
To gain access to the spare tire and jacking
equipment, do the following:
1. Turn the wing nut on
the compact spare
tire cover
counterclockwise to
remove it. Then
remove the cover.
2. Turn the nut holding the jack counterclockwise
and remove it. Then remove the jack and
wheel wrench.
3. Remove the compact spare tire. SeeCompact
Spare Tire (CTS Only) on page 434for more
information about the compact spare tire.
425

4. The tools you will be using next include the
jack (A) and the wheel wrench (B).
Removing the Flat Tire and
Installing the Spare Tire (CTS Only)
1. Loosen the wheel nuts, but do not remove
them yet, using the wheel wrench. Turn the
handle about 180 degrees, then return
the handle back to the starting position.
This avoids taking the wrench off the lug nut
for each turn.
426

2. Find the jacking location using the diagram
above and corresponding triangular-shaped
hoisting notches located in the plastic molding.
The front location (A) is about 14 inches
(35.6 cm) from the rear edge of the front wheel
well, and the rear location (B) is about 7 inches
(17.8 cm) from the front edge of the rear
wheel well.3. Attach the wheel wrench to the jack.
{CAUTION:
Getting under a vehicle when it is jacked
up is dangerous. If the vehicle slips off
the jack you could be badly injured or
killed. Never get under a vehicle when it is
supported only by a jack.
427

{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.
{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 t the jack lift head
into the proper location before raising the
vehicle.
428

Notice:If you position the jack under the
rocker molding and attempt to raise the
vehicle, you could break the molding and/or
cause other damage to your vehicle. Always
position the jack so that when the jack head is
raised, it will t rmly in the notch located
inboard from the rocker molding.
4. Turn the wheel wrench counterclockwise to
lower the jack lift head until the jack ts
under the vehicle.
5. Raise the jack by turning the wheel wrench
clockwise until the slots in the jack head t
into the metal ange located behind the
triangle on the plastic molding as shown.
6. Put the compact spare tire near you.
429

7. Raise the vehicle by turning the wheel wrench
clockwise. Raise the vehicle far enough off
the ground for the compact spare tire to
t under the vehicle.8. Remove all the
wheel nuts and take
off the at tire.
{CAUTION:
Rust or dirt on the wheel, or on the parts
to which it is fastened, can make the
wheel nuts become loose after time.
The wheel could come off and cause an
accident. When you change a wheel,
remove any rust or dirt from the places
where the wheel attaches to the vehicle.
