FLAT TIRE: You will hear two chimes when this
message is displayed followed by the message MAX
SPEED 55 MPH (90 km/h). If this message appears, do
not drive your vehicle above these limits. The next
message to appear is REDUCED HANDLING. Adjust
your driving accordingly. To acknowledge these
warnings, press RESET. After you press RESET, a
message will reappear and you will hear a chime every
10 minutes until this condition changes. This message
indicates that the pressure in one of your tires is lower
than 5 psi (34 kPa). Next to the FLAT TIRE message,
you can see either LF (left front), LR (left rear), RF
(right front) or RR (right rear) to indicate to you which
tire is flat. 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 RESET. 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 your Tire Loading Information Label. See
ªExtended Mobility Tiresº and ªTire Inflationº in
the Index.
CAUTION:
When the LOW TIRE PRESSURE or FLAT
TIRE 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 LOW TIRE PRESSURE or FLAT TIRE
message is displayed. Drive cautiously, and check
your tire pressures as soon as you can.

HIGH TIRE PRESSURE - (LF, LR, RF, RR): Yo u
will hear two chimes when this message is displayed. To
acknowledge the warning, press RESET. After you press
RESET, a message will reappear and you will hear a
chime every 10 minutes until this condition changes.
This message indicates that the pressure in one of your
tires is higher than 42 psi (290 kPa). Next to the HIGH
TIRE PRESSURE message, you can see either LF
(left front), LR (left rear), RF (right front) or RR (right
rear) to indicate to you which tire is higher than 42 psi
(290 kPa). 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 RESET. 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 your Tire Loading Information Label.
See ªExtended Mobility Tiresº and ªTire Inflationº
in the Index.SERVICE TIRE MON SYS: If this message comes on,
a part on the Tire Pressure Monitor (TPM) is not
working properly. If you drive your vehicle while any of
the four sensors are missing or inoperable, the warning
will come on in approximately 10 minutes. If all four
sensors are missing, the warning will come on in
approximately 15 to 20 minutes. (All the sensors would
be missing, for example, if you put different wheels on
your vehicle without transferring the sensors.) If the
warning comes on and stays on, there may be a problem
with the TPM. See your dealer.

6-42 Extended Mobility Tires
Your vehicle, when new, had Goodyear Extended
Mobility Tires (EMT). There's no spare tire, no tire
changing equipment and no place to store a tire in the
vehicle. Extended Mobility Tires perform so well
without any air that a Tire Pressure Monitor (TPM) is
used to alert you if a tire has lost pressure.
The Tire Pressure Monitor (TPM) has a sensor on
each road wheel that transmits to a receiver on the
instrument panel.
The system operates on a radio frequency subject to
Federal Communications Commission (FCC) Rules and
with Industry and Science Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received,
including interference that may cause
undesired operation.
This device complies with RSS
-210 of Industry and
Science Canada. Operation is subject to the following
two conditions: (1) this device may not cause
interference, and (2) this device must accept any
interference received, including interference that may
cause undesired operation of the device.Changes or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.
If a tire's inflation pressure is between 5 psi (35 kPa)
and 25 psi (170 kPa), you will see a message on the
Driver Information Center. This message will show
which tire is underinflated and two chimes will sound.
An example would be LOW TIRE PRESSURE
-LR.
This would mean that the inflation pressure in your left
rear tire is between 5 psi (35 kPa) and 25 psi (170 kPa).
If the inflation pressure in the tire drops below 5 psi
(35 kPa), the message would read FLAT TIRE
-LR and
four chimes will sound. See ªDriver Information
Centerº in the Index.
The TPM will also alert you if a tire's pressure is higher
than 42 psi (290 kPa). The message will show which tire
is overinflated and two chimes will sound. An example
would be HIGH PRESSURE
-LR. This would mean that
the inflation pressure in your left rear tire is higher than
42 psi (290 kPa). See ªDriver Information Centerº in
the Index.
If a tire pressure message appears on the Driver
Information Center, stop as soon as you can. Have the
tire pressures checked and set to those shown on your
Tire Loading Information label. See ªInflation
-- Tire
Pressureº in the Index.

6-45 Inflation -- Tire Pressure
The Tire-Loading Information label, which is on the
rear edge of the driver's door, shows the correct
inflation pressures for your tires when they're cold.
ªColdº means your vehicle has been sitting for at least
three hours or driven no more than 1 mile (1.6 km).
NOTICE:
Don't let anyone tell you that underinflation or
overinflation is all right. It's not. If your tires
don't have enough air (underinflation), you can
get the following:

Too much flexing

Too much heat

Tire overloading

Bad wear

Bad handling

Bad fuel economy.
NOTICE: (Continued)
NOTICE: (Continued)
If your tires have too much air (overinflation),
you can get the following:

Unusual wear

Bad handling

Rough ride

Needless damage from road hazards.
When to Check
Check your tires once a month or more.
How to Check
With the Tire Pressure Monitor, you can check tire
inflation pressures while driving. After you've reached a
speed of 15 mph (24 km/h) or more, press and release
the GAGES button on the Driver Information Center
(DIC) until the front tire pressures are displayed. Then,
press and release the GAGES button for the rear tire
pressures. If the display doesn't show tire pressure, or if
the SERVICE TIRE MON SYS message appears, see
your dealer for service.

Part B: Owner Checks and Services
Listed in this part are owner checks and services which
should be performed at the intervals specified to help
ensure the safety, dependability and emission control
performance of your vehicle.
Be sure any necessary repairs are completed at once.
Whenever any fluids or lubricants are added to your
vehicle, make sure they are the proper ones, as shown in
Part D.
At Each Fuel Fill
It is important for you or a service station attendant to
perform these underhood checks at each fuel fill.
Engine Oil Level Check
Check the engine oil level and add the proper oil if
necessary. See ªEngine Oilº in the Index for
further details.
Engine Coolant Level Check
Check the engine coolant level and add DEX
-COOL

coolant mixture if necessary. See ªEngine Coolantº in
the Index for further details.Windshield Washer Fluid Level Check
Check the windshield washer fluid level in the
windshield washer tank and add the proper fluid if
necessary. See ªWindshield Washer Fluidº in the Index
for further details.
At Least Once a Month
Tire Inflation Check
Make sure tires are inflated to the correct pressures.
See ªTiresº in the Index for further details.
Cassette Deck Service
Clean cassette deck. Cleaning should be done every
50 hours of tape play. See ªAudio Systemsº in the Index
for further details.
