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 440.
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 444.
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 349.
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 349.Run-Flat Tires (STS-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
System (TPMS) which will alert you if there is a
loss of tire pressure in any of the tires. See
Tire Pressure Monitor System on page 433.
{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.
429

If you will be driving at high speeds, speeds of
100 mph (160 km/h) or higher, where it is legal, set
the cold ination pressure to the maximum ination
pressure shown on the tire sidewall, or 38 psi
(265 kPa), whichever is lower. See the example
following. When you end this high-speed driving,
return the tires to the cold ination pressure shown
on the Tire and Loading Information label. See
Loading Your Vehicle on page 349.
Example:
You will nd the maximum load and ination
pressure molded on the tire’s sidewall, in small
letters, near the rim ange. It will read something
like this: Maximum load 690 kg (1521 lbs)
300 kPa (44 psi) Max. Press.
For this example, you would set the ination
pressure for high-speed driving at
38 psi (265 kPa).Tire Pressure Monitor System
Your vehicle has a Tire Pressure Monitor
System (TPMS). This system uses radio and
sensor technology to check tire pressure levels.
Sensors are mounted onto each tire and
wheel assembly, except the compact spare tire
and wheel. The TPMS sensors monitor the
air pressure in your vehicle’s tires and transmits
the tire pressure readings to a receiver located in
the vehicle.
Using the Driver Information Center (DIC), tire
pressure levels may be viewed by the driver. For
additional information and details about the
DIC operation and displays seeDIC Controls and
Displays on page 258andDIC Warnings and
Messages on page 264.
If a low tire pressure condition is detected, the
TPMS will display the CHECK TIRE PRESSURE
warning message on the DIC display and, at
the same time, illuminate the low tire pressure
warning symbol, on the instrument panel cluster.
433

Run-Flat Tires (STS-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. 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) when the low tire warning light
is displayed. Drive cautiously and check
your tire pressures as soon as you can.SeeRun-Flat Tires (STS-V) on page 429andTire
Pressure Monitor System on page 433, 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.
To order a service manual seeService
Publications Ordering Information on page 543.
Tire Inator Kit
Your vehicle has a tire inator kit. There is no jack
or spare tire. The kit uses a liquid tire sealant
and air at the same time to seal small punctures
in the tread area of the tire. Be sure to read
and follow all of the tire inator kit instructions.
