Low as pect rat io tires
Yo ur Audi is fac tory-equipped with l ow aspec t ratio tires . Thes e tires
have been thorough ly tested and been selected specifically for your
m odel f or their superb pe rformance, r oad feel and hand ling under
a variety of driving conditions . Ask your authorized Audi dealer for
m ore deta ils .
T he low aspec t rat io of these ti res is indicated by a nu meral o f
55 or
less
in the tire's si ze designation. The numeral represents the ratio
o f the tire's sid ewa ll heig ht in relat ion t o it s tread w idth express ed
in percentage. Conventiona l tires have a height/width ratio of 60 or
m ore .
The performance of low -aspect -ratio tires is particularly sensitive to
improper inflation pressure . It is therefore important that low
aspect ratio tires are inflated to the specified pres sure and that the
i nflation pressure is regularly checked and maintained . Tire pres­
sures should be checked at least once a month and alway s before a
long trip ~
page 293, "Checking tire pr essure".
What you can do to avoid tire and rim damage
Lo w aspec t r ati o t ir es ca n be da maged more easi ly by impact wi th
potholes, curbs, gullies or ridges on the road, particularly if the tire
i s un derinflate d.
In order to minimize t he occurrence o f impac t damage to the t ires
of your vehicle , we recommend that you observe the following
p recau tions:
• Always ma intain recommended inflation pressures . Check your
t ire pressure every 2,000 miles (3,000 k m) and ad d air i f neces sa ry .
• D rive careful ly on roads with potholes, deep gullies or ridges.
Th e impa ct from driving throug h or over such o bstacles can
damage your tires. Impact with a curb may also cause damage to
you r ti res .
• After any impact, immediately inspect your tires or have them
inspected by the neares t autho rize d Audi deale r. R eplace a
damaged tire as soon as possib le.
• I nspect you r tir es eve ry 2 ,0 0 0 m iles (3 ,000 k m) for damage a nd
wear. Damage is not always easy to see. Damage can lead to loss of
a ir and under infla tion , wh ic h co ul d even tually cause tire fa ilu re . If
you believe t hat a tire may have been damaged , rep lace the tire as
soon as p ossi ble.
• T hese tires may wear more quickly than others .
• Please also re member th at, wh ile t hese tir es de liver respo nsive
handling, they may ride less comfortably and make more noise than
ot her c hoic es.

Tire pressure monitoring system
Ap plies to v ehicles : w it h tir e p ressure monit orin g system
General notes ..J
Each tire, including the spare (if provided), should be checked
month ly when cold and inflated to the inflation pressure recom­
mended 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 pres ­
sure label, you should determine the proper tire inflation pressure
for those tires).
As an added safety feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that illuminates a low tire pressure tellta le when one or more o f your tires is significantly
under-inflated . Accordingly, when the low tire pressure te llta le i llu ­
minates, you should stop and check your tires as soon as poss ible,
and inflate them to the proper pressure. Driving on a significantly
under -inflated tire causes the tire to overheat and can lead to tire
failure. Under-inflation also reduces fue l efficiency and tire tread
life, and may affect the vehicle's handling and stopping ability.
Please note tha t the TPMS is not a substitute for proper tire mainte­
nance, and it is the driver's responsibility to maintain correct tire
pressure, even if under -inflation has not reached the level to trigger
il lumination of the TPMS low tire pressure te lltale.
Your vehicle has also been equipped with a TPMS malfunction indi ­
cator to indicate when the system is not operat ing proper ly. The
TPMS malfunction indicator is combined with the low tire pressure
tel ltale . When the system detects a ma lfunction, the te lltale w ill flash for approximately one minute and then remain continuously
il lum inated . This sequence will continue upon subsequent veh ic le
start-ups as long as the malfunc tion exists .
When the ma lfunction indicator is illuminated, the system may not
be able to detect or signal low tire pressu re as intended . TPMS
malfunctions may occur for a variety of reasons, including the
insta llation of replacement or alternate tires or wheels on the
vehic le that prevent the TPMS from functioning properly . A lways
check the TPMS malfunction tellta le after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or
a lterna te tires and wheels allow the TPMS to continue to function
properly. •
