-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con
trol.
-Incorrect tire pressure in
creases tire wear and has a
negative effect on driving and

(D Note
Replace lost valve caps to re
duce the risk of damage to the
tire valves.
@ For the sake of the environment
Tire pressure that is too low in
creases fuel consumption.
(D Tips
Audi recommends using the
tire pressure specified for a normal load
q table on
page 243
or for a full load
when the vehicle is partially
loaded.
Make sure that the tire designa
tion on your tire matches the des
ignation on the tire pressure label
and the tire pressure table.
The following table lists recom
mended tire pressures in cold
tires according to the load and
the size of the tires installed. ..,
~ Check and correc t the seating of the snow
chains if necessary after driving a few feet. Fol
l ow the instructions from the manufacturer .
~ Note the maximum permitted speed when driv
ing with snow chains. Do not exceed 30 mph
(SO km/h) .
Snow chains not only improve the
driving in win
ter road cond itions, but also the
braking.
Use of snow chains is on ly permitted with certain
rim/tire combinations due to tec hnical reasons .
Check with an authorized Audi dealer or author ized repair facility to see if you may use snow
cha ins.
You must remove the chains when driving on roads that are
free of snow. When roads are free
of snow, snow chains can impair handling and
damage the t ires, and the chains w ill quickly be
destroyed .
A WARNING
Using incorrect snow chains o r installing snow
chains incorrect ly can result in loss of vehicle
c ont rol, w hic h in cr eases the risk of a n acci
de nt.
- Snow cha ins can damage the rims/wheel
covers* if the cha ins come into d irect con
tact wi th them . Remove the whee l cove rs*
first. Use coated snow cha ins.
- Usi ng snow chai ns tha t add more than 0.4
i nch (10.5 mm) of he igh t ca n severely dam
age the wheel ho usings and othe r vehicle
components .
- Do no t install and use s now chains if there is
a mal funct ion in the adaptive air suspen
sion*, because the vehicle height wi ll be
very low. If you d rive with snow chains any
way, the wheel ho usings and othe r vehicle
components can be severely damaged.
Low aspect ratio tires
Your Aud i is factory -equipped with low aspect ra
tio tires . These t ires have been tho rough ly tested
and been se lected specifically for yo ur model fo r
Wheel s
their superb performance, road fee l and handling
u nder a variety of driving conditions . Ask your au
thorized Audi dea le r fo r more detai ls.
T he low aspect rat io o f th ese tires is indicated by
a n umeral of
55 or le ss in the tire's size des igna
tion . The numera l represents the ratio of the
t ir e's s idewall height in relation to its tread w idth
expressed in percentage. Conventiona l tires have
a he ight/width ratio of 60 or more.
The performance of low-aspect- ratio tires is par
ticularly sen sitive to imprope r inflat ion pres
s ure. It is the refore important that low aspect
rat io tires are inflated to the speci fied pre ssure
and that the inflation pressure i s regularly
checked and m aintain ed. Tir e pr essures should
be checked at least once a month and always
b efor e a long trip
~ page 241.
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged more eas i
ly by impact w ith po tholes, curbs, gullies or
ridges on the road, particularly if the tire is un
deri nflated.
In orde r to m in imize the occurrence of impact
damage to t he tires of yo ur vehicle , we recom
me nd that you observe the following pre ca u
t ions:
- Always ma intain recommended inflat ion pres
sures. Check yo ur tir e pressure every 2,000
m iles (3 ,00 0 k m) and add air if necessary.
- Dr ive ca refully on roads w it h potholes, deep
gullies o r ridges. T he impact from dr iving
t hrough or over such obstacles can damage
your tires. Impac t wi th a curb may a lso ca use
damage to your tires.
- Afte r any impac t, immed iate ly inspect yo ur
t ires or have them inspected by the nearest au
thorized A udi dealer. Rep lace a damaged tire as
soon as possible.
- Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear. Damage is not a lways
easy to see. Damage can lead to loss of air and
underinflation, wh ich could eventually cause
tire fa ilure. If you believe that a tire may have
been damaged, replace the tire as soon as pos -
sible . .,.

Tire pressure monitoring
system
CD General notes
Each t ire, including the spare (if provided),
should be checked monthly when cold and inflat
ed to the inflation pressure recommended by the
veh icle manufac turer 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 inf lation pressure la
be l, you should determine the proper tire infla
tion pressure for those tires).
As an added safety feature, your veh icle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire press ure te ll
tale when one or more of your tires is significant l y under-inflated. Accordingly, when the low tire
pressure tellta le illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a s ignifi
cantly under-inflated tire causes the tire to over
heat and can lead to t ire failure. Unde r-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop
ping ability .
Please note that the TPMS is not a substitute for
proper tire maintenance, and i t is the driver's re
sponsib ility to ma inta in correct tire pressure,
even if under -inflation has not reached the level
to trigger illum inat ion of the TPMS low tire pres
sure telltale.
Your veh icle has also bee n eq uipp ed w ith a TPMS
mal function indicator to indicate when the sys
tem is not operating properly. The TPMS mal
function indicator is combined w ith the low tire
pressure tellta le. When the system detects a
malfunction, the telltale will flash for approxi
mately one minute and then remain cont inuously
illuminated . This sequence will continue upon
Wheels
subsequent vehicle start-ups as long as the mal
function exists .
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
i nsta llation of replacement or alternate tires or
whee ls on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS ma lfunction telltale after replac ing one or
more tires or wheels on your vehicle to ensure
that the replacement or a lternate tires and
whee ls allow the TPMS to continue to function
properly.
If the Tire Pressure Monitoring System
indicator appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system mo/function .
Fig. 197 Instrume nt cluste r: indicator light with message
Us ing the ABS sensors, the tir e pressure monitor
ing system compares the tire tread circumfer
ence and vibration characteristics of the individu
al tires. If the press ure changes in one or more
tires , this is indicated in the instrument cluster
display with an indicator light
ti] and a message.
If only one tire is affected, the location of that
tire will be indicated.
T he tire press ures must be stored in the Infotain
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle¢
page 250. The tire pressure moni
toring system only monitors the tire pressure you have stored. Refer to the tire pressure label for ..,.
