MILES RANGE: (Analog Cluster Only.) This message
shows about how many miles you can drive without
refilling your fuel tank. Once the range drops below
40 miles (64 km) remaining, the display will show LOW.
MPG INST (Instantaneous Miles per Gallon):This
message shows the instantaneous fuel economy which
varies with your driving conditions, such as
acceleration, braking and the grade of the road being
traveled. The INFO RESET button does not function in
this mode.
BATTERY VOLTS: This message shows the current
battery voltage. If the voltage is normal the display will
show BATTERY VOLTS OK. If the voltage drops
below 10.5 volts, the display will show BATTERY
VOLTS LOW. If the voltage is above 16 volts, the
display will show BATTERY VOLTS HIGH. If the
display shows the high or low message, you will need to
have your battery checked. See ªDriver Information
Center (DIC) Messagesº later in this section for
more information.LF-RF-LR-RR TIRE (If Equipped): On vehicles
equipped with the tire pressure monitor, this message
shows the tire pressure for each tire (left front, right
front, left rear and right rear). Pressing the INFO button
will scroll through the tire pressure for each of the
four tires, such as:

34 PSI LF TIRE OK or

234 kPa LF TIRE OK
If a tire pressure is below 25 PSI (172 kPa) or above
38 PSI (265 kPa), the message will appear as shown
above except it will show TIRE LOW or TIRE HIGH as
appropriate. If desired, the tire pressure information can
be programmed not to appear when using the INFO
button to scroll through the DIC displays. See ªVehicle
Programming and Personalization Featuresº in the Index.
If a low or high tire pressure is detected by the system
while driving, a CHECK TIRE PRESSURE message will
appear in the display. If this occurs, press the INFO
button to scroll to the tire(s) with a low or high pressure
condition. See ªDriver Information Center (DIC)
Messagesº later in this section for more information.
ENG/MET (English/Metric): Press this button to
display information in the English (miles) or metric
(kilometers) system.

system. If you see this message, try to reset the system
(stop, turn off the engine, then start the engine again).
If the SERVICE STABILITY SYS message still
comes on, it means there is a problem. You should see
your dealer for service. Reduce your speed and drive
accordingly. A single chime will also sound when this

the vehicle. The vehicle usually restarts, however, you
may want to take your vehicle to your dealer before
turning off the engine.

Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
If the TPM system detects low tire pressure, below
25 psi (172 kPa), or high tire pressure, above 38 psi
(262 kPa), a message, CHECK TIRE PRESSURE, will
appear on the Driver Information Center (DIC) display.
By pressing the INFO button, the DIC screen will show
which tire(s) has the low or high pressure condition.
See ªInflation
-- Tire Pressureº in the Index for
information regarding correct tire inflation. If a tire is
low, you should stop as soon as possible and check all
your tires for damage. If a tire is flat, see ªIf a Tire Goes
Flatº in the Index.
NOTICE:
Do not use a tire sealant if your vehicle is equipped
with Tire Pressure Monitors. The liquid sealant can
damage the tire pressure monitor sensors.
Once a low or high tire pressure condition is detected,
the TPM system will display the CHECK TIRE
MESSAGE each time the engine is started, until the
tire(s) are set to the correct inflation pressure.The Tire
-Loading Information Label, which is located
on the rear edge of the driver's door, shows the correct
inflation pressure for the tires on your vehicle.
The TPM system also allows the driver to check the air
pressure status of each road tire using the Driver
Information Center (DIC). Each tire's air pressure will
be listed individually, in the following order: LF (left
front or driver's side front tire), RF (right front or
passenger's side front tire), RR (right rear or passenger's
side rear tire) and LR (left rear or driver's side rear tire).
See ªInflation
-- Tire Pressureº in the Index for
information regarding correct tire inflation. Also, see
ªDriver Information Center (DIC)º in the Index for
information on the DIC controls and displays.
If the DIC display doesn't show tire pressures or the
SERVICE TPM SYSTEM message appears, see your
dealer for service. The TPM system may not work
properly while the compact spare tire is installed.
Anytime you replace one or more tires or rotate your
tires, the TPM system will need to be reset. A special
tool is needed to reset the sensor identification codes.
See your dealer for service.
The TPM system can alert you about a low or high tire
pressure condition, but it doesn't replace normal tire
maintenance. See ªTiresº in the Index.

6-52 Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See ªWhen It's Time for New Tiresº and
ªWheel Replacementº later in this section for
more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See ªScheduled
Maintenance Servicesº in the Index for scheduled
rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here.Don't include the compact spare tire in your
tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire
-Loading
Information label. Vehicles equipped with the Tire
Pressure Monitor (TPM) system will need to have the
sensors reset after a tire rotation is performed. A special
tool is needed to reset the sensor identification codes.
See your dealer for service. Make certain that all wheel
nuts are properly tightened. See ªWheel Nut Torqueº
in the Index.
CAUTION:
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after a time. The wheel could come off and cause
an accident. When you change a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this; but be
sure to use a scraper or wire brush later, if you
need to, to get all the rust or dirt off. See
ªChanging a Flat Tireº in the Index.
