may depart significantly from the norm due to

variations in driving habits, service practices and

differences in road characteristics and climate.

WARNING

Temperature grades apply to tires that are

properly inflated and not over or underinflat-

ed.

Traction

The traction grades, from highest to lowest, are

AA, A, B and C. Those grades represent the tire's

ability to stop on wet pavement as measured un-

der controlled conditions on specified govern-

ment test surfaces of asphalt and concrete. A tire

marked C may have poor traction performance

Tire pressure monitoring

system

 General notes

Each tire, including the spare (if provided),

should be checked monthly when cold and inflat-

ed to the inflation pressure recommended by the

vehicle manufacturer on the vehicle placard or

tire inflation pressure label. (If your vehicle has

tires of a different size than the size indicated on

the vehicle placard or tire inflation pressure la-

bel, you should determine the proper tire infla-

tion pressure for those tires).

Temperature

The temperature grades are A (the highest), B,

and C, representing the tire's resistance to the

generation of heat and its ability to dissipate

heat when tested under controlled conditions on

a specified indoor laboratory test wheel.

Sustained high temperature can cause the mate-

rial of the tire to degenerate and reduce tire life,

and excessive temperature can lead to sudden

As an added safety feature, your vehicle has been

equipped with a tire pressure monitoring system

(TPMS) that illuminates a low tire pressure tell-

tale when one or more of your tires is significant-

ly under-inflated. Accordingly, when the low tire

pressure telltale illuminates, you should stop and

check your tires as soon as possible, and inflate

them to the proper pressure. Driving on a signifi-

cantly under-inflated tire causes the tire to over-

heat and can lead to tire failure. Under-inflation

also reduces fuel efficiency and tire tread life,

and may affect the vehicle's handling and stop-

ping ability.

tire failure ð

The grade C corresponds to a level of perform-

ance which all passenger car tires must meet un-

der the Federal Motor Vehicle Safety Standard

No. 109. Grades B and A represent higher levels

of performance on the laboratory test wheel than

the minimum required by law.

WARNING

The traction grade assigned to this tire is

based on straight-ahead braking traction

tests, and does not include acceleration, cor-

nering, hydroplaning or peak traction charac-

teristics.

Please note that the TPMS is not a substitute for

proper tire maintenance, and it is the driver's re-

sponsibility to maintain correct tire pressure,

even if under-inflation has not reached the level

to trigger illumination of the TPMS low tire pres-

sure telltale.

WARNING

The temperature grade for this tire is estab-

lished for a tire that is properly inflated and

not overloaded. Excessive speed, underinfla-

tion, or excessive loading, either separately or

in combination, can cause heat buildup and

possible tire failure.

Your vehicle has also been equipped with a TPMS

malfunction indicator to indicate when the sys-

tem is not operating properly. The TPMS mal-

function indicator is combined with the low tire

pressure telltale. When the system detects a

malfunction, the telltale will flash for approxi-

mately one minute and then remain continuously

illuminated. This sequence will continue upon

with new tires

When the malfunction indicator is illuminated,

the system may not be able to detect or signal

low tire pressure as intended. TPMS malfunctions

may occur for a variety of reasons, including the

installation of replacement or alternate tires or

wheels on the vehicle that prevent the TPMS

from functioning properly. Always check the

TPMS malfunction telltale after replacing one or

more tires or wheels on your vehicle to ensure

that the replacement or alternate tires and

wheels allow the TPMS to continue to function

properly.

Indicator lights

If the  indicator light turns on, there is a loss

of pressure in at least one tire ð . Check the

tires and replace if necessary. Check and correct

the pressures of all four tires and store the pres-

sure again ðpage 288.

If you have not stored new tire pressures, but the

indicator light  is blinking and an audio signal

sounds, then drive to an authorized Audi dealer

or authorized Audi Service Facility immediately to

have the malfunction corrected.

If  appears after turning on the ignition or

while driving and the  indicator light in the in-

strument cluster blinks for approximately one

minute and then stays on, there is system mal-

function. Try to store the correct tire pressures

ðpage 288. In some cases, you must drive for

several minutes after storing the pressures until

the indicator light turns off. If the indicator light

does turn off or turns on again after a short peri-

od of time, drive to an authorized Audi dealer or

authorized Audi Service Facility immediately to

have the malfunction corrected.

Applies to: vehicles with Tire Pressure Monitoring System in-

dicator

The tire pressure indicator in the instrument

cluster informs you if the tire pressure is too low

or if there is a system malfunction.

Using the ABS sensors, the tire pressure monitor-

ing system compares the tire tread circumfer-

ence and vibration characteristics of the individu-

al tires. If the pressure changes in one or more

tires, this is indicated in the instrument cluster

display with an indicator light  and a message.

If only one tire is affected, the location of that

tire will be indicated.

WARNING

– If the tire pressure indicator appears in the

display, reduce your speed immediately and

avoid any hard steering or braking maneu-

vers. Stop as soon as possible and check the

tires and their pressure.

The tire pressures must be stored again each

time you change the pressures (switching be-

tween partial and full load pressure) or after

changing or replacing a tire on your vehicle

ðpage 288. The tire pressure monitoring system

only monitors the tire pressure you have stored.

Refer to the tire pressure label for the recom-

mended tire pressure for your vehicle

– The driver is responsible for maintaining the

correct tire pressure. You must check the

tire pressure regularly.

– Under certain conditions (such as a sporty

driving style, winter conditions, or unpaved

roads), the tire pressure monitoring system

indicator may be delayed.

ðpage 279, fig. 178.

Tire tread circumference and vibration character-

istics can change and cause a tire pressure warn-

ing if:

– The tire pressure in one or more tires is too low

– The tires have structural damage

Tips

– The tire pressure monitoring system can al-

so stop working when there is an ESC mal-

function.

– The tire was replaced or the tire pressure was

changed and it was not stored ðpage 288
