2007 CADILLAC CTS V flat tire

Tire Pressure Warning Message
When you see this
ashing symbol, one or
more of the vehicle’s
tires is either under
or over-inated.
To acknowledge this warning, press either button
on the outboard switch on the left spoke of the
steering wheel. There are three levels of warning
for this display:
1. High Tire Pressure (above 42 psi (290 kPa))
2. Low Tire Pressure (below 25 psi (170 kPa))
3. Flat Tire (below 5 psi (35 kPa))For conditions 1 and 2, this warning will ash
ve times and the display will then show the tire
pressure gage. For condition 3, this warning
will ash continuously until the driver
acknowledges it. In any of the three cases, the
warning will redisplay every 10 minutes until
the situation is corrected. Conditions 2 and 3 will
also display a warning light elsewhere on the
cluster that will stay on after this warning is
acknowledged. SeeTire Pressure Light (CTS-V
Only) on page 208for more information. Also see
Tire Pressure Monitor System on page 405for
more information on tire pressure specications.

(E) Tire Ply Material:The type of cord and
number of plies in the sidewall and under
the tread.
(F) Uniform Tire Quality Grading (UTQG):Tire
manufacturers are required to grade tires
based on three performance factors: treadwear,
traction, and temperature resistance. For more
information seeUniform Tire Quality Grading on
page 414.
(G) Maximum Cold Ination Load Limit:
Maximum load that can be carried and the
maximum pressure needed to support that load.
(A) Temporary Use Only:The compact spare
tire or temporary use tire has a tread life of
approximately 3,000 miles (5 000 km) and should
not be driven at speeds over 65 mph (105 km/h).
The compact spare tire is for emergency use
when a regular road tire has lost air and gone at.
If your vehicle has a compact spare tire, see
Compact Spare Tire (CTS Only) on page 434and
If a Tire Goes Flat on page 422.
Compact Spare Tire Example
395

Vehicle Capacity Weight:The number of
designated seating positions multiplied by 150 lbs
(68 kg) plus the rated cargo load. SeeLoading
Your Vehicle on page 321.
Vehicle Maximum Load on the Tire:Load on an
individual tire due to curb weight, accessory
weight, occupant weight, and cargo weight.
Vehicle Placard:A label permanently attached to
a vehicle showing the vehicle’s capacity weight
and the original equipment tire size and
recommended ination pressure. See “Tire and
Loading Information Label” underLoading
Your Vehicle on page 321.
Run-Flat Tires (CTS-V)
If your vehicle has run-at tires, there is no spare
tire and no tire changing equipment. 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. SeeTire Pressure Monitor
System on page 405.
{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.
If a tire goes at, you will not need to stop on the
side of the road to change the tire. You can
just keep on driving. The tire can operate
effectively with no air pressure for up to 65 miles
(105 km) at speeds up to 55 mph (90 km/h).
The shorter the distance you drive and the slower
the speed, the greater the chance that the tire
will not have to be replaced. When a tire is lled
with air, it provides a cushion between the
road and the wheel.
400

When rotating your vehicle’s tires, always use the
correct rotation pattern shown here.
If your vehicle has a compact spare tire, do not
include it in the tire rotation.
After the tires have been rotated, adjust the front
and rear ination pressures as shown on the Tire
and Loading Information label. SeeLoading Your
Vehicle on page 321, for an example of the tire and
loading information label and its location on your
vehicle.
If your vehicle has the Tire Pressure Monitor
System (TPMS) the TPMS sensors will need to be
reset and matched to the tire/wheel position. A
special TPMS diagnostic tool is used to reset the
sensor identication codes. See your dealer for
service.Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specications on page 457.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make 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 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 needed, to get all the rust or dirt
off. SeeChanging a Flat Tire (CTS Only)
on page 424.

Each new wheel should have the same
load-carrying capacity, diameter, width, offset and
be mounted the same way as the one it replaces.
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 (CTS Only) on page 424
for more information.
Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You cannot know how it has
been used or how far it has been driven.
It could fail suddenly and cause a crash.
If you have to replace a wheel, use a new
GM original equipment wheel.
417

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.
