Section 6 Service and Appearance Care
6-1

Speed Rating:An alphanumeric code assigned to
a tire indicating the maximum speed at which a
tire can operate.
Traction
:The friction between the tire and the
road surface. The amount of grip provided.
Tread
:The portion of a tire that comes into
contact with the road.
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 6-61.
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 6-64.
Vehicle Capacity Weight
:The number of
designated seating positions multiplied by
150 lbs (68 kg) plus the rated cargo load.
SeeLoading the Vehicle on page 5-21.
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
the Vehicle on page 5-21.
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.

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 the tires properly. If air
goes out of a tire, it is much more likely to leak out
slowly. SeeTires on page 6-46for additional
information.
This 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 6-52
andTire Pressure Monitor System on page 6-55.
6-72

{CAUTION:
When the TIRE FLAT MAX SPD 55, REDUCED
HNDLG message is displayed on the Driver
Information Center, the vehicle’s handling
capabilities will be reduced during severe
maneuvers. If you drive too fast, you could lose
control of the 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
the 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 3-57andDIC Warnings and Messages
on page 3-60for 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 the 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 the
vehicle’s run-at tires. This damage would not be
covered by warranty. Do not use liquid sealants
in the vehicle’s run-at tires.
To order a service manual, seeService Publications
Ordering Information on page 8-15.
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 5-6.
