Treadwear Indicators:Narrow bands, sometimes
called wear bars, that show across the tread of
a tire when only 1/16 inch (1.6 mm) of tread
remains. SeeWhen It Is Time for New Tires on
page 6-66.
UTQGS (Uniform Tire Quality Grading
Standards)
:A tire information system that
provides consumers with ratings for a tire’s
traction, temperature, and treadwear. Ratings are
determined by tire manufacturers using
government testing procedures. The ratings are
molded into the sidewall of the tire. SeeUniform
Tire Quality Grading on page 6-69.
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 5-22.
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 5-22.
Run-Flat Tires
Your vehicle, when new, had run-at tires. There is no
spare tire, no tire changing equipment, and no place
to store a tire in the vehicle. Run-at tires perform
so well without any air that a Tire Pressure Monitor
System (TPMS) is used to alert you if a tire has
lost pressure.
{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 shorter the distance you drive and the
slower the speed, the greater the chance that the tire

3. Lift the vehicle with the jack, making sure the jack
spans at least two of the crossmember ribs (B).
For more information, seeDoing Your Own Service
Work on page 6-4.
If a Tire Goes Flat
It is unusual for a tire to blow out while you are driving,
especially if you maintain your tires properly. If air
goes out of a tire, it is much more likely to leak out
slowly. SeeTires on page 6-52for additional
information.
Your vehicle, when new, had run-at tires. This type of
tire can operate effectively with no air pressure, so
you will not need to stop on the side of the road
to change a at tire. You can just keep on driving.
The shorter the distance you drive and the slower the
speed, the greater the chance that the run-at tire
will not have to be replaced. Run-at tires perform so
well without any air that a Tire Pressure Monitor (TPM)
is used to alert you if a tire has lost pressure.
SeeRun-Flat Tires on page 6-58andTire Pressure
Monitor System on page 6-61.

{CAUTION:
When the TIRE FLAT MAX SPD 55, REDUCED
HNDLG message is displayed on the Driver
Information Center, 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. Don’t drive over 55 mph
(90 km/h) when the TIRE FLAT MAX SPD 55,
REDUCED HNDLG message is displayed.
Drive cautiously and check your tire pressures
as soon as you can.
If the TPM system detects a tire pressure below
5 psi (34 kPa), the TIRE FLAT MAX SPD 55, REDUCED
HNDLG warning message is displayed on the Driver
Information Center (DIC). SeeDIC Operation and
Displays on page 3-60andDIC Warnings and Messages
on page 3-63for information and details about the
DIC operation and displays.
{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.
Notice:Using liquid sealants can damage the tire
valves and tire pressure monitor sensors in your
vehicle’s run-at tires. This damage would not
be covered by warranty. Do not use liquid sealants
in your vehicle’s run-at tires.
To order a service manual, seeService Publications
Ordering Information on page 8-16.
If a tire goes at, the stability control system will turn
on automatically even if it was disabled by the driver.
When a at tire condition exists the StabiliTrak
®system
cannot be turned off. SeeStabiliTrak®System on
page 5-8.
