Winter tires
Winter tires can improve vehicle handling on snow and
ice. At temperatures below 45 °F (7 °C) we recommend
changing to winter tires .
In some heavy snow areas, local governments may require true
winter or "snow" tires, those with very deeply cut tread . These tires
should only be used in pairs and be installed on a ll four wheels.
Make sure you purchase snow tires that are the same size and
construction type as the other tires on your vehicle.
Your vehicle is equipped with all -whee l drive, this wi ll improve trac ­
tion during winter driving, even with the standard tires. However,
we strong ly recommend that you a lways equip all four whee ls on
your vehicle with correctly fitted winter tires or all-season tires,
when winter road conditions are expected. This also improves the
vehicle's braking performance and reduces stopp ing distances.
Summer tires provide less grip on ice and snow.
Winter tires (snow ti res) must a lways be fitted on a ll four wheels.
Compatible tire pressure monitoring sensors must be installed on
a ll fou r winter tires for the tire pressure monitoring system* to func ­
tion proper ly=>
page 301.
Ask your authorized Audi dealer or qualified workshop for permitted
wint er tire size s. Use only radial winter tires.
Winter tires lose their effectiveness when the tread is worn down to a depth of 0.157 inch (4 mm).
Only drive with winter tires under winter conditions. Summer tires
handle better when there is no snow or ice on the roads and the
temperature is above 45 °F (7 °C) .
If you have a flat tire, see notes on spare wheel =>
page 299.
Please always remember that winter tires may have a lower speed
rat ing than the tires originally installed on your vehicle at the time
it was manufactured. Please see=>
page 300, "Speed rating (letter code)" for a listing of the speed
rating letter codes and the
maximum speed at which the tires can be driven .
T he speed rating letter code(=>
page 290) is on the side wall of the
tire =>
page 299.

& WARNING
Using the wrong snow chains for your vehicle or installing them
incorrectly can increase the risk of loss of control leading to
serious per sonal injury.
• Snow chains are available in different sizes. Always make sure
to follow the instructions provided by the snow chain manufac ­
turer.
• When driving with snow chains never drive faster than the
speed permitted for your specific snow chains.
• Always observe local regulations .
0 Note
• Remove snow chains before driving on roads not covered with
s no w to avoid da mag ing tires a nd wea ring the s now cha ins down
unnecessari ly. •
Snow chains, which come into direct contact with the wheel rim,
can s cratch or damage i t. Therefo re, ma ke s ure t hat the sn ow cha ins
are suitably covered . Check the pos itio n of the snow c hains after
driv ing a few ya rds a nd co rrec t if necessa ry . Fo llow the i nstr uct ions
from the snow chain manufacturer when doing so.

& WARNING
Improperly tightened or mainta ined wheel bolts can become loose
causing loss of control , a collision and serious personal injury .
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolts can turn easily and be properly tightened.
• Never grease or oil the wheel bolts and the threads in the wheel
hubs . They can become loose while driving if greased or oiled ,
even if tightened to the specified torque .
• Only use wheel bolts that belong to the rim being installed .
• Never use different wheels bolt s on your vehicle.

& WARN ING (continued )
• Always maintain the correct tightening torque for the wheel
bolt s to reduce the risk of a wheel loss . If the tightening torque of
the wheel bolts is too low, they can loo sen and come out when the
vehicle is moving . If the tightening torque is too high , the wheel
bolts and threads can be d amaged and the wheel can be come
loose .
0 Note
The specified torque for the whee l bo lts is 90 ft lbs . (120 Nm) with a
tolerance of ± 7,4 ft lbs .(± 10 Nml. Torque wheel bo lts diagona lly.
Af te r cha ng ing a whe el, the torque mus t be checked as so on as
possible with a torque wrench -preferably by an authorized Audi
dea ler o r qua lified w orksh op.•
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. •

& WARNING
• If the tire pressure indicator appears in the instrument cluster
display, one or more of your tires is significantly under -inflated .
Reduce your speed immediately and avoid any hard steering or
braking maneuvers. Stop as soon as possible and check the tires
and their pressures . Inflate the tire pressure to the proper pressure
as indicated on the vehicle's tire pressure label
=> page 291.
Driving on a significantly under -inflated tire causes the tire to over ­
heat and can lead to tire failure . Under-inflation also is likely to
impair the vehicle's handling and stopping ability .
• The driver is responsible for maintaining the correct tire pres­
sures . You must check the tire pressures regularly .
• Under certain conditions (such as a sporty driving style , winter
conditions or unpaved roads ), the pressure monitor indicator may
be delayed.
• Ask your authorized Audi dealer if run -flat tires may be used on
your vehicle. Your vehicle registration becomes invalid if you use
these tires when not permitted . Damage to your vehi cle or acci­
dents could also result.
