HIGH TIRE PRESSURE
This message displays when one or more of the tires is
over-inated. This message also displays LEFT FRONT,
RIGHT FRONT, LEFT REAR, or RIGHT REAR to
indicate which tire is affected. You can receive more
than one tire pressure message at a time. To read other
messages that may have been sent at the same time,
press the RESET button. If a tire pressure message
appears on the DIC, stop as soon as you can. Have the
tire pressures checked and set to those shown on the
Tire Loading Information label. SeeRun-Flat Tires
on page 5-64,Loading the Vehicle on page 4-24,
Inflation - Tire Pressure on page 5-66, andTire Pressure
Monitor System on page 5-68. The DIC also shows
the tire pressure values. SeeDIC Operation and
Displays on page 3-52.
To acknowledge the message, press the RESET button.
A message reappears every 10 minutes until the
condition is corrected.
HOT ENGINE AIR CONDITIONING OFF
This message displays when the engine coolant
becomes hotter than the normal operating temperature.
To avoid added strain on a hot engine, the air
conditioning compressor is automatically turned off.When the coolant temperature returns to normal, the
A/C operation automatically resumes. You can continue
to drive your vehicle. If this message continues to
appear, have the system repaired by your dealer/retailer
as soon as possible to avoid compressor damage.
ICE POSSIBLE
This message displays when the outside air temperature
is cold enough to create icy road conditions. Adjust
your driving accordingly.
LOW FUEL
This message displays when the fuel tank is less than
10 percent full and the display is turned off. A multiple
chime also sounds when this message is displayed.
Rell the fuel tank as soon as possible. SeeFuel Gage
on page 3-50.
LOW OIL PRESSURE
This message displays if low oil pressure levels occur.
If this message appears while the engine is running,
stop the engine and do not operate it until the cause of
low oil pressure is corrected. Severe damage to the
engine can result. A multiple chime sounds when this
message is displayed. SeeEngine Oil on page 5-17.

LOW TIRE PRESSURE
{CAUTION:
When the LOW TIRE PRESSURE or TIRE FLAT
message is displayed on the Driver Information
Center, your vehicle’s handling capabilities
will be reduced during severe maneuvers.
The active handling system will be affected.
SeeActive Handling System on page 4-7.
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 PRESSURE or TIRE FLAT message
is displayed. Drive cautiously and check your
tire pressures as soon as you can.
This message displays when one or more of the tires
is under-inated. This message also displays LEFT
FRONT, RIGHT FRONT, LEFT REAR, or RIGHT REAR

at a time. To read other messages that may have
been sent at the same time, press the RESET button.
If a tire pressure message appears on the DIC, stop as
soon as you can. Have the tire pressures checked
and set to those shown on the Tire Loading Information
label. SeeRun-Flat Tires on page 5-64,Loading the
Vehicle on page 4-24,Inflation - Tire Pressure on
page 5-66, andTire Pressure Monitor System on
page 5-68. The DIC also shows the tire pressure values.
SeeDIC Operation and Displays on page 3-52.
To acknowledge the message, press the RESET button.
A message reappears every 10 minutes until the
condition is corrected.TOO COLD TO MOVE TOP
This message displays and a chime sounds when the

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 5-73.
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 5-76.
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 4-24.
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 4-24.
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 Flat
Your vehicle has no spare tire, no tire changing
equipment, and no place to store a tire.
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 5-58for 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 System (TPMS) is used to
alert you if a tire has lost pressure. SeeRun-Flat Tires on
page 5-64andTire Pressure Monitor System on
page 5-68.{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.
