Vehicles with P235/65R18,
P235/55R20, or 235/55R20 size
tires require inflation pressure
adjustment when driving
your vehicle at speeds of
160 km/h (100 mph) or higher.
Set the cold inflation pressure to
the maximum inflation pressure
shown on the tire sidewall,
or 260 kPa (38 psi), whichever
is lower. When you end this
high-speed driving, return the tires
to the cold tire inflation pressure
shown on the Tire and Loading
Information label. SeeVehicle
Load Limits on page 9‑12 and
Tire Pressure on page 10‑61.
You will find the maximum load and
inflation pressure molded on the
tire's sidewall, in small letters,
near the rim flange. It will read
something like this: Maximum load
690 kg (1521 lbs) 300 kPa (44 psi)
Max. Press.Tire Pressure Monitor
System
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your tires and
transmit tire pressure readings to
a receiver located in the vehicle.
Each tire, including the spare
(if provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on
the vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire inflation pressure label, you
should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a
tire pressure monitoring system
(TPMS) that illuminates a low tire pressure telltale when one or
more of your tires is significantly
under‐inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them
to the proper pressure. Driving on
a significantly under‐inflated tire
causes the tire to overheat and can
lead to tire failure. Under‐inflation
also reduces fuel efficiency and
tire tread life, and may affect the
vehicle's handling and stopping
ability.
Please note that the TPMS is
not a substitute for proper tire
maintenance, and it is the driver's
responsibility to maintain correct
tire pressure, even if under‐inflation
has not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been
equipped with a TPMS malfunction
indicator to indicate when the
system is not operating properly.

Vehicle Care 10-65
Using the DIC, tire pressure levels
can be viewed by the driver.
For additional information and
details about the DIC operation
and displays seeDriver Information
Center (DIC) on page 5‑28.
The low tire pressure warning
light may come on in cool weather
when the vehicle is first started, and
then turn off as you start to drive.
This could be an early indicator that
the air pressure in the tire(s) are
getting low and need to be inflated
to the proper pressure.
A Tire and Loading Information
label, attached to your vehicle,
shows the size of your vehicle's
original equipment tires and the
correct inflation pressure for your
vehicle's tires when they are cold.
See Vehicle Load Limits on
page 9‑12, for an example of the
Tire and Loading Information label
and its location on your vehicle.
Also see Tire Pressure on
page 10‑61. Your vehicle's TPMS can warn you
about a low tire pressure condition
but it does not replace normal tire
maintenance. See
Tire Inspection
on page 10‑68, Tire Rotation on
page 10‑68 andTires on
page 10‑54.
Notice: Tire sealant materials are
not all the same. A non-approved
tire sealant could damage the Tire
Pressure Monitor System (TPMS)
sensors. TPMS sensor damage
caused by using an incorrect
tire sealant is not covered by
the vehicle warranty. Always use
only the GM approved tire sealant
available through your dealer or
included in the vehicle.
Factory-installed Tire Inflator Kits
use a GM approved liquid tire
sealant. Using non-approved tire
sealants could damage the TPMS
sensors. See Tire Sealant and
Compressor Kit on page 10‑79 for
information regarding the inflator
kit materials and instructions.TPMS Malfunction Light and
Message
The TPMS will not function properly
if one or more of the TPMS sensors
are missing or inoperable. When the
system detects a malfunction, the
low tire warning light flashes for
about one minute and then stays
on for the remainder of the ignition
cycle. A DIC warning message is
also displayed. The low tire warning
light and DIC warning message
come on at each ignition cycle until
the problem is corrected. Some of
the conditions that can cause the
malfunction light and DIC message
to come on are:
.One of the road tires has been
replaced with the spare tire.
The spare tire does not have
a TPMS sensor. The TPMS
malfunction light and DIC
message should go off once
you re‐install the road tire
containing the TPMS sensor.

10-68 Vehicle Care
Tire Inspection
We recommend that you
regularly inspect your vehicle's
tires, including the spare tire,
if the vehicle has one, for signs
of wear or damage at least once
a month.
Always remove the tires 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 cannot
be repaired well because of
the size or location of the
damage.
Tire Rotation
Tires should be rotated
every 12 000 km (7,500 miles).
SeeScheduled Maintenance on
page 11‑2.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that the vehicle
continues to perform most like it
did when the tires were new.
Any time you notice unusual
wear, rotate the tires as soon
as possible and check wheel
alignment. Also check for
damaged tires or wheels. See
When It Is Time for New
Tires on page 10‑69 andWheel
Replacement on page 10‑75.
When rotating the vehicle's tires,
always use the correct rotation
pattern shown here.
Do not include the compact
spare tire in the tire rotation.

GM's exclusive TPC Spec
system considers over a dozen
critical specifications that impact
the overall performance of
your vehicle, including brake
system performance, ride
and handling, traction control,
and tire pressure monitoring
performance. GM's TPC Spec
number is molded onto the
tire's sidewall near the tire size.
If the tires have an all‐season
tread design, the TPC Spec
number will be followed by an
MS for mud and snow. SeeTire
Sidewall Labeling on page 10‑55
for additional information.
GM recommends replacing tires
in sets of four. This is because
uniform tread depth on all tires
will help keep your vehicle performing most like it did
when the tires were new.
Replacing less than a full set
of tires can affect the braking
and handling performance of
your vehicle. See
Tire Inspection
on page 10‑68 andTire Rotation
on page 10‑68 for information
on proper tire rotation.
{WARNING
Tires could explode during
improper service. You or others
could be injured or killed if you
attempt to mount or dismount
a tire. Only your dealer or an
authorized tire service center
should mount and dismount
the tires.
{WARNING
Mixing tires could cause you
to lose control while driving.
If you mix tires of different
sizes, brands, or types
(radial and bias-belted tires),
the vehicle may not handle
properly, and you could have
a crash. Using tires of different
sizes, brands, or types may
also cause damage to your
vehicle. Be sure to use the
correct size, brand, and type
of tires on all wheels. It is
all right to drive with your
compact spare temporarily, as
it was developed for use on
your vehicle. See Compact
Spare Tire on page 10‑93.

Black plate (72,1)Cadillac SRX Owner Manual - 2011
10-72 Vehicle Care
{WARNING
If you use bias-ply tires on the
vehicle, the wheel rim flanges
could develop cracks after
many miles of driving. A tire
and/or wheel could fail
suddenly, causing a crash.
Use only radial-ply tires with
the wheels on the vehicle.
If you must replace your
vehicle's tires with those that do
not have a TPC Spec number,
make sure they are the same
size, load range, speed rating,
and construction type (radial
and bias‐belted tires) as your
vehicle's original tires. Vehicles that have a tire
pressure monitoring system
could give an inaccurate
low‐pressure warning if
non‐TPC Spec rated tires
are installed on your vehicle.
Non‐TPC Spec rated tires may
give a low‐pressure warning
that is higher or lower than the
proper warning level you would
get with TPC Spec rated tires.
See
Tire Pressure Monitor
System on page 10‑63.
Your vehicle's original
equipment tires are listed on
the Tire and Loading Information
label. See Vehicle Load
Limits on page 9‑12 for more
information about the Tire and
Loading Information label and
its location on your vehicle.Different Size Tires and
Wheels
If you add wheels or tires that are
a different size than your original
equipment wheels and tires, this
could affect the way your vehicle
performs, including its braking,
ride and handling characteristics,
stability, and resistance to rollover.
Additionally, if your vehicle has
electronic systems such as antilock
brakes, rollover airbags, traction
control, and electronic stability
control, the performance of these
systems can be affected.

Black plate (73,1)Cadillac SRX Owner Manual - 2011
Vehicle Care 10-73
{WARNING
If you add different sized wheels,
your vehicle may not provide
an acceptable level of
performance and safety if tires
not recommended for those
wheels are selected. You may
increase the chance that you will
crash and suffer serious injury.
Only use GM specific wheel and
tire systems developed for your
vehicle, and have them properly
installed by a GM certified
technician.
See Buying New Tires on
page 10‑70 andAccessories
and Modifications on page 10‑3
for additional information.
Uniform Tire Quality
Grading
Quality grades can be found
where applicable on the tire
sidewall between tread shoulder
and maximum section width.
For example:
Treadwear 200 Traction AA
Temperature A
The following information relates
to the system developed by the
United States National Highway
Traffic Safety Administration
(NHTSA), which grades tires
by treadwear, traction, and
temperature performance.
This applies only to vehicles
sold in the United States.
The grades are molded on the
sidewalls of most passenger car
tires. The Uniform Tire Quality Grading (UTQG) system
does not apply to deep
tread, winter-type snow tires,
space-saver, or temporary use
spare tires, tires with nominal
rim diameters of 10 to 12 inches
(25 to 30 cm), or to some
limited-production tires.
While the tires available on
General Motors passenger
cars and light trucks may vary
with respect to these grades,
they must also conform to
federal safety requirements and
additional General Motors Tire
Performance Criteria (TPC)
standards.
All Passenger Car Tires Must
Conform to Federal Safety
Requirements In Addition
To These Grades.

Used Replacement Wheels
{WARNING
Putting a used wheel on the
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.
Tire Chains
{WARNING
Do not use tire chains. There is
not enough clearance. Tire chains
used on a vehicle without the
proper amount of clearance can
cause damage to the brakes,
suspension or other vehicle parts.
The area damaged by the tire
chains could cause you to lose
control of the vehicle and you or
others may be injured in a crash.(Continued)
WARNING (Continued)
Use another type of traction
device only if its manufacturer
recommends it for use on the
vehicle and tire size combination
and road conditions. Follow that
manufacturer's instructions.
To help avoid damage to the
vehicle, drive slowly, readjust
or remove the device if it is
contacting the vehicle, and do not
spin the vehicle's wheels. If you
do find traction devices that will
fit, install them on the front tires.

When reinstalling the wheel cover
or center cap on the full-size tire,
tighten all five plastic caps hand
snug with the aid of the wheel
wrench and tighten them with
the wheel wrench an additional
one‐quarter of a turn.
Notice:Wheel covers will not fit
on your vehicle's compact spare.
If you try to put a wheel cover on
the compact spare, the cover or
the spare could be damaged.
Storing a Flat or Spare Tire
and Tools
{WARNING
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. To store the flat or spare tire and
tools:
1. Open the liftgate. See
Liftgate
(Manual) on page 2‑14 or
Liftgate (Power) on page 2‑15
for more information.
2. Put back all tools as they were stored in the rear storage
compartment and put the
compartment cover back on.
For more information, see
“Storing the Compact Spare Tire
and Tools” next in this section.
3. Install the cargo cover. For more information, see
Cargo Management System on
page 4‑5.
4. Place the tire, lying flat, in the rear storage compartment.
5. Attach the strap to the cargotie-down in the rear of the
vehicle.

Vehicle Care 10-93
6. Route the strap through thewheel, as shown.
7. Attach the strap to the other cargo tie-down in the rear of the
vehicle.
8. Tighten the strap.
The compact spare is for temporary
use only. Replace the compact
spare tire with a full-size tire as
soon as you can.
Compact Spare Tire
{WARNING
Driving with more than one
compact spare tire at a time
could result in loss of braking
and handling. This could lead
to a crash and you or others
could be injured. Use only one
compact spare tire at a time.
If this vehicle has a compact
spare tire, it was fully inflated when
the vehicle was new; however, it
can lose air after a time. Check the
inflation pressure regularly. It should
be 420 kPa (60 psi).
After installing the compact
spare on the vehicle, stop as
soon as possible and make sure
the spare tire is correctly inflated.
The compact spare is made to
perform well at speeds up to
105 km/h (65 mph) for distances up
to 5 000 km (3,000 miles), so you
can finish your trip and have the full-size tire repaired or replaced at
your convenience. Of course, it is
best to replace the spare with a
full-size tire as soon as possible.
The spare tire will last longer and
be in good shape in case it is
needed again.
Notice:
When the compact
spare is installed, do not take
the vehicle through an automatic
car wash with guide rails. The
compact spare can get caught on
the rails which can damage the
tire, wheel and other parts of the
vehicle.
Do not use the compact spare on
other vehicles.
Do not mix the compact spare tire
or wheel with other wheels or tires.
They will not fit. Keep the spare tire
and its wheel together.
Notice: Tire chains will not fit the
compact spare. Using them can
damage the vehicle and can
damage the chains too. Do not
use tire chains on the compact
spare.

Be sure to follow all steps of the
dinghy towing procedure prior to
and after towing the vehicle.
Once the destination has been
reached:
1. Shift the vehicle to P (Park).
2. Reinstall the BCM fuses. See Instrument Panel Fuse
Block on page 10‑49.
3. Disconnect the vehicle from the tow vehicle. Notice:
Too much or too
little fluid can damage the
transmission. Be sure that
the transmission fluid is at the
proper level before towing with
all four wheels on the ground.
Notice: Do not tow a vehicle
with the front drive wheels on
the ground if one of the front
tires is a compact spare tire.
Towing with two different tire
sizes on the front of the vehicle
can cause severe damage to the
transmission.
Dolly Towing
(All-Wheel‐Drive Vehicles)
All-wheel‐drive vehicles should not
be towed with two wheels on the
ground. To properly tow these
vehicles, they should be placed on
a platform trailer with all four wheels
off of the ground or dinghy towed
from the front. See Dinghy Towing
earlier in this section.
Dolly Towing
(Front-Wheel‐ Drive Vehicles)
To tow the vehicle from the front
with the rear wheels on the ground,
do the following:
1. Put the front wheels on a dolly.
2. Move the shift lever to P (Park).
See Shifting Into Park on
page 9‑22.
3. Set the parking brake.
