New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au­
thorized repair facility. These fa ­
cilities have the proper knowl ­
edge and are equipped with the
required tools and replacement
parts .
.,,. New tires do not yet have the
opt imum adhesion properties.
Drive carefully and at moderate
speeds for the first 350 m iles
(500 km) with new tires .
... use tires of the same construc­
tion, size (rolling circumference)
and as close to the same tread pattern as possible on all four

Audi Original equipment tires. If
you would like to use different
tires, please note that the tires may perform differently even if
they are the same size¢,&..

The spare tire* is diffe rent from
the regular tires installed on the
vehicle - for example, if winter
tires or wide tires are installed -
then only use the spare tire* tem­
porarily in case of emergency and
drive carefully while it is in use . It
should be replaced with a regular
tire as soon as possible.
All four whee ls must be equipped
with tires that are the same brand
and have the same construction
and tread pattern so that the
drive system is not damaged by different tire speeds. For this rea-

use a spare tire* that is the same
circumference as the regular
tires .
A WARNING
-Only use tire/rim combina­
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
-For technical reasons, it is not
possible to use tires from oth­
er vehicles -in some cases,
you cannot even use tires from the same vehicle model.
-Make sure that the tires you select have enough clearance
to the vehicle. Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of an accident.
-Only use tires that are more than 6 years old when abso-
244
lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on
your vehicle. Using them when not permitted can lead to ve­
hicle damage or accidents.
-If you install wheel covers on
the vehicle, make sure they al­
low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage

The correct tire pressure for tires
mounted in the factory and for
the spare tire* is indicated on a la­
bel. The label is located on the B­
pillar
c:> fig. 207, c> fig. 208.
When the vehicle is partially load­
ed (up to 3 people), use the tire
pressure specified for normal
loads
c:> table on page 248. If
driving the vehicle when fully loaded, you must increase the tire
246
before every long drive.
•Always check the tire pressure
when the tires are
cold. Do not
reduce the pressure if it increas­
es when the tires are warm.
•Check the label
c:> fig. 208 for
the correct tire pressure based
on vehicle load.
•Correct the tire pressure if nec­
essary.
•Vehicles with Tire Pressure Mon­
itoring System*: store the modi­
fied tire pressure in the Infotain­ ment system
c:> page 255.
•Check the pressure in the emer­
gency tire*/spare tire*. Always
maintain the maximum temper­
ature that is specified for the
tire.
A WARNING ~
Always adapt the tire pressure
to your driving style and vehicle load.
-Overloading can lead to loss of
vehicle control and increase

_& WARNING
Temperature grades apply to tires that are
properly inflated and not over or underinf lat ­
ed.
Tire pressure monitoring system
U) General notes
Applies to: vehicles with tire pressure monito ring system
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflat ion pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
bel, you should determine the proper tire infla­
tion pressure fo r those tir es) .
As an added safety feature, your vehicle has been
equipped with a t ire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant­
ly under-inflated . Accord ingly, when the low tire
p ressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to tire failure. Under-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 it is the driver's re­
sponsib ility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunct ion indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is comb ined w ith the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi­
mately one minute and then remain cont inuous ly
illuminated. This sequence will continue upon
254
subsequent vehicle start-ups as long as the mal­
function exists.
When the malfunction indicator is illum inated,
the system may not be able to detect or s ignal
low tire pressure as intended . TPMS malfunctions
may occur for a variety of reasons, including the
i nstallation of replacement or alternate tires or
wheels on the vehicle 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 replacement or alternate tires and
whee ls allow the TPMS to continue to function
properly.
If the Tire Pressure Monitoring System
indicator appears
Applies to: vehicles with tire pressure monitoring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Fig . 209 Instrument cl uste r: indicator light with me ssage
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread c ircumfer­
ence and v ibration characteristics of the individu­
al tires.
If the pressure changes in one or more
ti res, this is ind icated in the instrument cluster
display with an indicator light
[I] and a message.
If only one tire is affected, the locat ion of that
tire will be indicated.
The tire pressures 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 255. The tire pressure moni­
tor ing system only monitors the tire pressure you
have stored . Refer to the t ire pressure label for ..,.

Depending on the equipment, the vehicle tool kit
may be located under the spare tire under an ad­
d itional cover or in the too l box. The position of
the vehicle jack* may vary.
A WARNING
Improper use of the vehicle jack can cause se­
r ious personal injuries.
- Never use the screw driver hex head to
t ighten wheel bolts, since the bolts cannot
attain the necessary tighten ing torque if you
use the hex head, potentia lly causing an ac­
c ident.
- The factory-supplied jack is intended on ly
for your vehicle model. Under no circum­
stances should it be used to lift heavy
vehicles or other loads; yo u risk injuring
yo urself.
- Never start the engine whe n the vehicle is
raise d, which could ca use a n accident.
- Support the veh icle secure ly with appropr i­
a te stands if wor k is to be perfo rmed u nder ­
neath the veh icle; otherwise, the re is a po­
tential risk for in jury.
- Never use the jack s upplied with your Audi
on another vehicle, particularly o n a heav ier
one. The jack is only suitab le for use on the
vehicle it came wit h.
@ Tips
The vehicle j ack* in your vehicle is mainte ­
nance -free.

and tire.
T here are some restr ictions on the use of the
compact spare tire. The compact spa re tire has
been designed specifically for your type of vehi­
cle . It must not be swapped with a compact
spare tire from another type of vehicle.
Snow chains
For technical reasons, the use of snow chains on
the compact spare tire is
not permitted. .,..
257

Emerg ency assis ta nce
If you do have to drive with snow chains and a
front tire fails, mount the spare wheel with tire
instead of a rear tire . Install the snow chains on
the rear tire and use it to replace the defective
front tire.
A WARNING
- Never use the spare tire if it is damaged or if
it is worn down to the tread wear indicators.
- If the spare tire is more than 6 years old,
use it only in an emergency and with ex­
treme caution and ca refu l dr iving .
- The spare tire is intended only for tempora­
ry and short-term use . It should be replaced
as soon as possible with the normal wheel
and t ire.
- After mounti ng the compact spare t ire, the
tire pressure must be checked as soon as possible. The tire pressure of the compac t
spare tire must be 4.2 bar; otherwise, you risk having an accident.
- Do not drive faster than SO mph (80 km/h).
Yo u risk hav ing an accident.
- Avoid full-throttle accelerat ion, heavy brak­
ing, and fast cornering. You risk having an
acc ident .
- Never dr ive using more than one spare
wheel and tire. You risk having an acciden t.
- Normal summer or winter tires must not be
mounted on the compact spare wheel rim.
- For technical reasons, the use of tire chains
on the spare tire is not pe rm itted. If it is
necessary to drive with tire chains, the spare
wheel m ust be mounted on the front ax le in
the event of a flat in a rear tire. The new ly
available front wheel must then be insta lled
in place of the rear wheel with the flat t ire.
Installing the tire chain before mounting
the wheel and t ire is recommended.

264
-Pull the reversible blade from the screwdriv­
er before you use the hexagonal socket in
the handle to turn the wheel bolts.
- When mounting tires with
unidirectional
tread design
make sure the tread pattern is
pointed the right way¢
page 264.
-The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the
mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be­
fore remounting the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design mus t be
mounted with their tread pattern pointed in the
right direction .
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spare tire with a tread pattern in­
tended for use in a specific direction, please note
the following:
- The direction of rotation is marked by an arrow
on the side of the tire.
- If the spare tire has to be installed in the incor­
rect direction, use the spare tire only tempora­
rily since the tire will not be able to achieve its
optimum performance characteristics with re­
gard to aquaplaning, noise and wear.
- We recommend that you pay particular atten ­
tion to this fact during wet weather and that
you adjust your speed to match road condi­ tions.
- Replace the flat tire with a new one and have it
installed on your vehicle as soon as possible to
restore the handling advantages of a unidirec­
tional tire.
Notes on wheel changing
Please read the information¢ page 243 if you
are going to use a spare tire which is different
from the tires on your vehicle.
