Cast (light) alloy wheels
Cast (light) alloy w heels require special care.
- Wash the wheels with a sponge or hose brush every
o th er week .
- For deep cleaning afte rwards, use only a dedicated
acid
free
cast a lloy wheel c leaner.
- Rub a coat of
liquid wa x onto the rims every t hree month.
Be sure to reac h and treat all parts of the rim.
To preserve the decorative appearance of the cast alloy wheels,
some special care is necessary. In add ition to road dirt and salt,
brake dust is also corrosive . If left on for too long, brake dust can
cause p itting.
Use on ly spec ial
acid -free cleaners formu lated for a lloy rims . Safe
products are available at your authorized Audi dealer. Never leave
t he cleaner on the rims longer than specif ied on the label. If not
rinsed off promptly, the acid contained in some cleaners can attack
t he threads on t he wheel bolts.
Never use abrasive or metal po lishing c leaning agents . If the protec
t ive coating has been chipped, e.g . by kicked up road dirt, touch it
up as soon as possible.

& WARNING
• Using incorrect or unm atched t ires and / or wheels o r improper
tire and wheel combinations can lead to lo ss of control , collision
and se rious per sonal injury .
• Always use tires , rim s and wheel bolts that meet the specifica
t ions of original f actory -installed tire s or other combinations that
have been spe cifically approved by the vehicle manufacturer .
• T ires age even if they are not being used and can fail suddenly ,
especially at high speeds . Tires that are more than 6 years old c an
only be used in an emergen cy and then with spec ial care and at
lower speeds .
• Never mount used tires on your vehi cle if you are not sure of
their "previou s history." Old used tires may have been damaged
e ven though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
• All four wheels must be fitted w ith radial tires of the same type ,
size (rolling circumference ) and the same tread pattern . Driving
with different tires reduces veh icle handling and can lead to a loss
of control.
• If the spare t ire is not the same as the tires that are mounted
on the vehicle -for example with winter tires -only use the spare
tire for a short period of time and drive with e xtra care . Refit the
normal road wheel as soon as safely possible.
• Never drive faster than the ma ximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Overloading tires cause heat build -up , sudden tire failure,
in cluding a blowout and sudden deflation and lo ss of control.
• Tempe rature grades apply to tires that are properly inflated and
not over or under inflated .
• For technical reasons it i s not always po ssible to use wheel s
from other veh icles - in some cases not even wheels from the
same vehicle model .
& WARNING (continued )
• If you install wheel trim discs on the vehicle wheels, make sure
that the air flow to the brakes is not blocked . Reduced airflow to
the brakes can them to overheat , increasing stopping distances
and causing a collision .
• Run flat tires may only be used on vehicles that were equipped
with them at the factory . The vehicle must have a cha ssis designed
for run flat tires and a fa ctory-installed tire pressure monitoring
system* that indicates a loss of tire pressure. Incorrect use of run
flat tires can lead to vehicle damage or acc idents . Check with an
authorized Audi dealer or tire specialist to see if your vehicle can
be equ ipped with run f lat tires . If run flat t ires are used , they must
be installed on all four wheels . Mixing tire types is not permitted.
0 Note
• For technical r eas ons, it is not gen erally possible t o us e the
whee l rims from other veh icles . ihis can ho ld true for whee ls of the
same veh ic le type.
• I f the spare tire is different from the tires that you have mounted
o n yo ur vehicl e (f or example wi nter tires or wide p rofile t ires), then
use the spare tire for a short period of time on ly and drive with extra
care . Rep lace the flat tire wi th the ti re m atchi ng t he o thers on you r
vehic le as soon as possib le.
• I f you should put diff ere nt w heels and tires o n your v ehicle (e. g.
winter wheels and tires), you must be certain that the wheels and
t ires are c ompatib le wi th the tire p ressu re monitoring system* .
Otherwise the system will register a malfunction and a fau lt
mes sage will be displayed . For more info rmation, contact your
author ized Aud i dea ler.

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
