(over-ination), you can get
the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road
hazards
9-54 Vehicle Care

A vehicle specific Tire and
Loading Information label
is attached to your vehicle.
This label shows your vehicle’s
original equipment tires and the
correct inflation pressures for
your tires when they are cold.
The recommended cold tire
inflation pressure, shown on the
label, is the minimum amount of
air pressure needed to support
your vehicle’s maximum load
carrying capacity.
For additional information
regarding how much weight
your vehicle can carry, and an
example of the Tire and Loading
Information label, seeVehicle
Load Limits on page 8-12.
How you load your vehicle
affects vehicle handling and
ride comfort. Never load your
vehicle with more weight than
it was designed to carry.When to Check
Check your tires once a
month or more. Do not forget
to check the compact spare
tire, if the vehicle has one.
The compact spare should be at
60 psi (420 kPa). For additional
information regarding the
compact spare tire, seeCompact
Spare Tire on page 9-83.
How to Check
Use a good quality pocket-type
gage to check tire pressure.
You cannot tell if your tires are
properly inflated simply by
looking at them. Radial tires may
look properly inflated even when
they are under-inflated. Check
the tire’s inflation pressure when
the tires are cold. Cold means
your vehicle has been sitting for
at least three hours or driven no
more than 1 mile (1.6 km).Remove the valve cap from the
tire valve stem. Press the tire
gage firmly onto the valve to
get a pressure measurement.
If the cold tire inflation pressure
matches the recommended
pressure on the Tire and Loading
Information label, no further
adjustment is necessary. If the
inflation pressure is low, add air
until you reach the recommended
amount.
If you overfill the tire, release air
by pushing on the metal stem
in the center of the tire valve.
Re-check the tire pressure with
the tire gage.
Be sure to put the valve caps
back on the valve stems.
They help prevent leaks by
keeping out dirt and moisture.
Vehicle Care 9-55

Tire Pressure for
High-Speed Operation
{WARNING
Driving at high speeds, 100 mph
(160 km/h) or higher, puts an
additional strain on tires. Sustained
high-speed driving causes
excessive heat build up and
can cause sudden tire failure.
You could have a crash and you
or others could be killed. Some
high-speed rated tires require
inflation pressure adjustment for
high speed operation. When speed
limits and road conditions are such
that a vehicle can be driven at high
speeds, make sure the tires are
rated for high speed operation, in
excellent condition, and set to the
correct cold tire inflation pressure
for the vehicle load.Vehicles with 245/45ZR20 103Y,
P245/50ZR19 104W and
275/40ZR20 106Y size tires,
have tires capable of high speed
use. Make sure the tires are inflated
to the recommended cold inflation
pressures before operating the
vehicle at speeds over 100 mph
(160 km/h). SeeVehicle Load Limits
on page 8-12andTire Pressure on
page 9-54.
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 vehicle’s 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 thevehicle 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.
9-56 Vehicle Care

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. The TPMS
malfunction indicator is combined
with the low tire pressure telltale.
When the system detects a
malfunction, the telltale will flash
for approximately one minute and
then remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as
long as the malfunction exists.
When the malfunction indicator is
illuminated, the system may not
be able to detect or signal low
tire pressure as intended. TPMS
malfunctions may occur for a varietyof reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow
the TPMS to continue to function
properly.
SeeTire Pressure Monitor
Operation on page 9-57for
additional information.

Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS is designed to warn the
driver when a low tire pressure
condition exists. TPMS sensors are
mounted onto each tire and wheel
assembly, excluding the spare tire
and wheel assembly, if the vehicle
has one. The TPMS sensors monitor
the air pressure in the vehicle’s tires
and transmits the tire pressure
readings to a receiver located in
the vehicle.
Using the Driver Information
Center (DIC), the driver can also
check tire pressure levels using the
DIC. For additional information and
details about the DIC operation and
displays seeTire Messages on
page 4-36.
Vehicle Care 9-57

When a low tire pressure condition
is detected, the TPMS illuminates
the low tire pressure warning
light located on the instrument
panel cluster.
A DIC warning message to check
the pressure in a specific tire is also
shown on the DIC display screen.
The low tire pressure warning light
and the DIC warning message come
at each ignition cycle until the tires
are inflated to the correct inflation
pressure.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.
The 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 the tires
when they are cold. SeeVehicle
Load Limits on page 8-12, for an
example of the Tire and Loading
Information label and its location on
your vehicle. Also seeTire Pressure
on page 9-54.
Your vehicle’s TPMS can warn you
about a low tire pressure condition
but it does not replace normal tiremaintenance. SeeTire Inspection
on page 9-61,Tire Rotation on
page 9-61andTires on page 9-48.
Notice:Using non-approved tire
sealants 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 the
GM approved tire sealant available
through your dealer/retailer.
Factory-installed Tire Inflator Kits
use a GM approved liquid tire
sealant. Using non-approved tire
sealants could damage the TPMS
sensors. SeeTire Sealant and
Compressor Kit on page 9-71for
information regarding the inflator
kit materials and instructions.
