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 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.

2-106
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 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
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.
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.

6-44
The valve stems on your extended mobility tires have
sensors that are part of the TPM. These sensors contain
batteries which are designed to last for 10 years under
normal driving conditions. See your dealer if you ever
need to have a wheel replaced, or if the sensors ever
need replacement.
NOTICE:
Using liquid sealants can damage the tire valves
and tire pressure monitor sensors in your
extended mobility tires. This damage would not
be covered by warranty. Don't use liquid sealants
in your extended mobility tires.
If you feel that winter tires are needed for your driving
conditions, Goodyear Eagle M+S EMT tires are
available in your original equipment sizes from an
authorized Goodyear EMT retailer. These tires will
improve snow traction while maintaining your
Corvette's extended mobility feature. When using winter
tires on your vehicle, be sure to use them on all four
wheels. See ªBuying New Tiresº in the Index.
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)

6-45
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.
Tire Rotation
The tires on your vehicle are different sizes front to rear.
Due to this, your tires should not be rotated. Each tire
and wheel should be used only in the position it is in.
When It's Time for New Tires
One way to tell when
it's time for new tires
is to check the
treadwear indicators,
which will appear
when your tires have
only 1/16 inch
(1.6 mm) or less of
tread remaining.

Part B: Owner Checks and Services
Listed in this part are owner checks and services which

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
