Snow chains
Snow chains may be fitted on ly to the front
wheels, and only to certain tire sizes. Ask your
authorized Audi dealer on whic h tire sizes
snow chains can be used.
I f you are going to use snow chains , then you
must install them on the front wheels at
l east.
The snow chains must have low-profile links
and must not be thicker than 0.4 inch (10 ,5 mm), including the lock .
Remove wheel center covers and tr im discs
before putting snow cha ins on your vehicle
c:;, Q) _ For safety reasons cover caps must the n
be fitted over the whee l bolts. These are ava il­
ab le from authorized Audi dea lers.
A WARNING
Using the wrong snow chains for yo ur vehi ­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
ser ious personal inj ury.
- Snow chains are ava ilable in different
sizes. Always make sure to follow the in­
struct ions provided by the snow chain
manufacturer .
- When driving w ith snow chains never
dr ive faster than the speed permitted for
your specific snow cha ins.
- Always observe local regulat ions .
([) Note
-Remove snow cha ins before driving on
roads not covered with snow to avoid
damaging t ires and wear ing the snow
chains down unnecessar ily.
- Snow chains, wh ich come into d irect con­
tact with the wheel rim, can scratch or
damage it . Therefore, make sure that the
snow chains are suitab ly covered . Check
the position of the snow chains after
driving a few yards and correct if neces­
sa ry. Follow the i nstructions from the
snow cha in manufacture r when doing so.
- If the Adaptive Air Suspension* should
malfunction, do no t mo unt or use snow chains because the vehicle will be ex
­
treme ly low. If you do drive with snow
chains on while the vehicle is at this lev ­
el, the snow cha ins might severely dam­
age the whee lhouse and other parts of
the vehicle .
(D Tips
Where snow chains are mandatory on cer­
tain roads, th is normally a lso applies to
vehicles with all-wheel drive.
Wheel bolts
Wheel bol ts mus t alway s be tightened to the
correc t torque.
The design of wheel bolts is matched to the
factory installed rims . If different r ims are fit­
ted, the correct wheel bol ts with the righ t
length and correct ly shaped bolt heads must
be used . T his ensures that wheels are fitted
securely and that the b rake system functions
co rrect ly.
In certa in circumstances, you may not use
wheel bolts from a different veh icle -even if it
is the same model
c:;, page 275 .
A WARNING
Imp rope rly t ightened or ma inta ined wheel
bo lts can become loose c ausing loss of
control, a col lision and serio us pe rsonal i n­
jury .
- Always keep the wheel bo lts and the
threads in the wheel hubs clean so the
wheel bo lts can turn easily and be prop­
erly tightened.
- Never g rease or oil the wheel bolts and
the threads in t he wheel hubs . They can
become loose while driv ing if greased or
oiled, even if t ightened to the specified
torque.
- On ly use wheel bolts that belong to the
rim being installed .
- Never use different wheels bolts on yo ur
veh icle.
- Always maintain the correct t ightening
torque for the whee l bolts to reduce the

risk of a wheel loss . If the tightening tor­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cle is moving. If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel can be­
c ome loose.
(D Note
The spec ified torque for the wheel bo lts is
90 ft lb (120 Nm) w ith a tolerance of ± 7,4
ft lb(± 10 Nm) . Torque wheel bo lts d iago­
na lly . After chang ing a wheel, the torque
m ust be che cked as soon as possib le w it h a
t orque wrenc h -preferab ly by an a utho r­
ized Audi dealer or qualified workshop.
Low aspect ratio tires
Your Audi is factory-equipp ed with low aspect
ratio t ires. These t ires have been thorough ly
tested and been selected spec ifically for your
model for the ir superb performance, road feel
and handling unde r a va riety of driving condi­
tions. Ask your a uthorized Aud i dea le r fo r
mo re deta ils.
T he low aspect ratio of these tires is indicated
by a nume ral of
55 or less in the tire's size
des ignation . T he numeral represents the rat io
of the ti re's sidewall height in relat io n t o its
tread wid th expressed in per cen tage . C o nven­
tional t ires have a height/width ra tio of 60 or
mo re.
Th e performan ce of low -aspe ct-ratio tir es is
parti cularl y se nsitive to improper inflation
pressure . It is therefore impor tant that low
a s pect ratio tire s are inflated to the specified
pressure and that the inflation pre ssure is
regularly checked and maintained. Ti re pres­
sures should be checked at least once a
month and always before a long trip
c::> page 234, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
eas ily by impact with potho les, curbs, gu llies
Tire s an d wheel s 245
or r idges on the road, partic ularly if the tire is
u nderinflated.
In orde r to minimize t he occ urren ce of impact
dam age to the tires o f your vehi cle, we recom ­
mend that you observe the following p reca u­
tions:
- Always ma int ain re commended inflation
pressu res . Check your tire pressu re eve ry
2,000 miles ( 3,000 km) and add air if neces ­
sary.
- Dr ive ca re fu lly on roads with potholes, deep
gullies o r ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires .
- After any impact, immed iate ly inspect your
tires or have them inspected by the nearest
au thor ized Audi dealer. Replace a damaged
tire as soon as possible .
- Inspect your tires every 2,000 m iles (3,000
km) for damage and wear. Damage is no t al­
ways easy to see . Damage can lead to loss of
air a nd under inflat ion, which could eventu­
ally cause tire failure .
If you believe that a
t ire may have been damaged, rep lace the
t ire as soon as possib le.
- These tires may wear more quickly tha n oth­
ers.
- Please also remember that, while these tires
de live r respon sive handling, they may ride
less comfo rtably and m ake more noise tha n
other choi ces .
Reduced performance in winter /cold
season conditions
A ll ti res are designed for cer ta in p urposes.
T he low aspect ratio, ult ra h igh performance
tires originally installed on your vehicle are i n­
tended for maxim um dry and wet road per­
f ormance and handling. They are not suitable
for cold , snowy or icy weather condi tions. If
you drive under those circumstances, you
shou ld equ ip your vehicle w it h all -season or
winter tires, which offer bette r traction under
those conditions. We suggest you use the rec­
ommended snow o r all-season t ires specified
f o r yo ur vehicle , or t hei r equivalent . .,..

Tire pressure
monitoring system
(D General notes
Each tire, including the spare (if provided) ,
should be checked monthly when cold and in­
flated 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 in­
flation pressure label, you shou ld determine
the proper tire inflation pressure for those
tires).
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor ing
system (TPMS) that illuminates a low tire
p ressure telltale when one or more of your
tires is significantly under-inflated. According­
ly, when the low tire pressure telltale illumi­
nates, you should stop and check your tires as
soon as possible, and inflate them to the proper pressure. Driving on a significantly un­
der-inflated tire causes the tire to overheat
and can lead to tire failure . Under -inflation al­
so reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and
stopping ab ility.
Please note that the TPMS is not a subst itute
for proper tire maintenance, and it is the driv­
e r's responsib ility to ma inta in correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped w ith a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale . When the sys­
tem detects a malfunction, the te lltale will
flash for approximately one minute and then remain continuously illuminated. This se- quence will continue upon subsequent vehicle
start-ups as
long as the malfunction exists.
When the malfunction indicator is illum inat­
ed, the system may not be ab le to detect or
signal low tire pressure as intended . TPMS
malfunctions may occur for a variety of rea ­
sons, including the installation of replace­
ment or alternate tires or wheels on the vehi­
cle 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 re­
placement o r alternate ti res and wheels allow
the TPM S to cont inue to function properly.
Description
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
The system uses sensors that measure the
temperature and pressure in the tires. Theda­
ta is sent from these sensors to the control
module by radio frequency.
The tire pressure monitoring system shows
the current pressures and temperatures of the
tires in the Infotainment system
¢page 247.
It also compares the current tire pressures
with the stored pressures and gives a warning in the driver information system if the tire
pressure is different from what is stored
¢ page 247.
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures. You must resave the tire pressures
¢page 248:
- eve ry time the tire p ressu res change, for ex­
ample when the load in the vehicle changes,
- after replacing a t ire, or
- if wheels w ith new wheel sensors are used .
_&. WARNING
-The tire pressu re monitoring sys tem as­
sists the driver in monitoring tire pres­
sures. The driver is responsible for having
the tires inflated to the correct pressure. ..,.

-Do not change the tire pressure when the
temperature of the tire is high. This
could result in serious damage to the tire
and even cause the tire to burst, increas­
ing the risk of an accident.
- A tire with low pressure flexes more. This
heats the tire up too much . Th is could
cause the tread to separate and even
cause the tire to burst, increasing the
risk of an accident .
- The tire pressure monitoring system
does not warn about damage or defects
in the tire construct ion that could cause
the tire to burst, for examp le. Inspect
your ti res regularly.
@) For the sake of the environment
Low tire pressure increases fuel consump­
tion and tire wear.
(D Tips
-If tires are replaced, the sensors/valves
do not need to be removed or replaced.
Just replace the valve stem and, if neces­
sary, the valve and the wheel electronics.
If you have questions, see your author­
ized Audi dealer or a qualified workshop.
- Using the tire mobility kit can results in
an incorrect display or a malfunction in
the tire pressure monitoring system.
Have the sensors replaced by an author­
ized Audi dealer or a qualified workshop.

The current tire pressures are shown in green
and yellow numbers:
-green: the current tire pressure and the
specified tire pressure are approximately the
same.
-yellow: the current tire pressure is too low
compared to the specified tire pressure.
The specified tire pressure is the last tire pres­
sure that was stored
c::> page 248
Note that the tire pressure also depends on
the temper ature of the tire . Every 50 °F
(10
°() increase in tire temperature results in
the tire pressure increas ing by approximately
0.1 bar . The tire pressure increases as the en­
gine becomes warmer while driving .

Storing new tire pressures
-
Correctly stored tire pressure specifications
are necessary for reliable tire pressure moni­
toring.
.,. Check the tire pressures in all wheels.
.,. If necessary, correct the tire pressure ac­
cording to the specifications on the sticker
on the side of the driver's door . Only correct
the pressure in tires whose temperature is
approximately the same as the ambient
temperature. If the temperature of the tire
is higher than ambient temperature, the tire
pressure must be increased approximately
0.2 bar above the value on the sticker.
.,. Switch on the ignition.
.,. Select :
I CARI function button > Car systems
> Tire pressure monitoring > Store tire pressures.
After storing,
the tire pressure
monitoring system measures the current
tire pressures and stores them as the new
specified pressures.
,. If the changed tire pressures are not dis­
played in the Infotainment system, drive the
veh icle for approx imately 10 minutes so
that the sensor signal from the wheels is re­
ceived aga in .
During this adaptation phase,--,--is displayed
for the pressure and temperature and the tire
pressure monitoring system is only partially
available.
It only provides a warning if one or
more tire pressures is be low the min imum
permitted spec ified pressure . If this is the
case, the
[fJ] indicator light appears with a

Malfunctions
Fig. 202 Display : indicator light with a message
-
If the tire pressure monitoring system is not
available,
the m indicator light appears in
the driver information system. The
[fJ] indica­
tor light also blinks for approximately one mi­
nutes each time the ignition is switched on.
The tire pressure monitoring system cannot be selected in the Infotainment system. The
malfunction could be caused by the following
examples:
- If the message appears at the end of the
adaptation phase, the system cannot detect
the wheels installed on the vehicle. This may
resu lt from one or more wheels being ..,.

installed without wheel sensors or with in­
compatible wheel sensors.
- A whee l sensor or another component has
failed.
- Using snow cha ins can affect the function of
the system because of the shie lding effect
of the chains.
- Th e tire pressure monitoring system is not
available due to a malfunction .
- Transmitters with the same frequency, such
as headphones or remote -contro lled devi­
ces, may cause a temporary system ma l­
function due to the strong electromagnetic
field.
The
ffim indicator light turns off once the ti re
press ure monitoring system is avai lab le again.
If you cannot correct the malfunction and the
m i ndicator light stays on, drive to an au­
thor ized Audi dealer or a qualified workshop
