The correct tire pressure for the
spare wheel is located on a la­
bel on the driver's side B-pillar.
Because technical changes may
be made to vehicle equipment
during the model year, always
compare the tire size designa­
tion on the tire pressure label
on your vehicle with the tires on
your vehicle. Make sure that the
tire size information on the ve­
hicle label is the same as the
size of the tires on the vehicle. This is especially important if
the vehicle belongs to someone
else or you bought the vehicle
with different rims/tires or you bought the vehicle as a previ­
ously owned vehicle.

through or over such obstacles can damage
your tires. Impact with a curb may also
cause damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Audi dealer. Rep lace a damaged
t ire as soon as possible.
- Inspect your t ires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see. Damage can lead to loss of air and underinflation, wh ich could eventu­
ally cause t ire failu re. If you bel ieve that a
t ire may have been damaged, replace the
t ire as soon as possible.
- These tires may wear more quickly than oth­
ers.
- Please also remember that, while these t ires
deliver respons ive handling, they may ride
less comfortably and make mo re no ise than

Reduced performance in winter /co ld
season condition s
All tires are des igned for certain pu rposes.
The low aspect ratio, ultra high pe rformance
tires orig inally installed on your veh icle are in­
tended for maximum dry and wet road per­
formance and handling. They are not suitable for cold, snowy or icy weather conditions. If
you dr ive under those circumstances, you
should equip your vehicle with all-season or
winter tires, which offer better traction under
those cond it ions. We suggest you use the rec­
ommended snow or a ll-season tires specified
for your vehi cle, or their equ ivalent.
Refer to¢
page 267 for more deta iled infor­
mat ion regarding winter tires.
Tire pressure
monitoring system
U) General notes
Each t ire, includ ing the spare (if provided),
should be checked monthly when cold and in­
flated to the inflation pressure recommended by the vehicle manufacture r on the vehicle
p lacard or tire inflation pressure label. (If your vehicle has tires of a diffe
rent size than the
size indicated on the vehicle placard or tire in­
flat ion pressure labe l, you shou ld determ ine
the proper t ire inflation pressure for those
t ires).
As an added safety feature, your ve hicle has
been equipped with a tire pressure monitoring
system (TPMS) that illum inates a low tire
pressure telltale when one or more of your
t ires is significantly under-inflated. According­
ly, when the low tire pressure telltale illumi­
nates, you shou ld stop and check you r tires as
soon as possib le, and inflate them to the
proper p ressu re. Driving on a sig nifican tly u n­
der- inflated t ire causes the tire to overheat
and can lead to tire fai lure . Under-inflation al­
so reduces fuel efficiency and tire tread life,
and may affect the vehicle 's hand ling and
stopp ing ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv­ er's respons ibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale .
Your vehicle has also been equipped with a
TPMS malfunction indicator to ind icate when
the system is not operating properly. The
TPMS ma lfunction indicator is combined w ith
the low tire pressure telltale . When the sys­
tem detects a malfunction, the telltale will
flash fo r approxima te ly one m inute and then
rema in continuously illum ina ted. This se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indica to r is illum inat­
ed, the system m ay not be ab le to detect or
signal low tire pressure as intended . TPMS
malfunctions may occur for a var iety of rea­
sons, incl uding the insta llation 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
whee ls on you r vehicle to ensu re that the re­
placement o r alternate ti res and wheels a llow
the TPM S to cont inue to func tion p roperly.

Tire pressure 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 malfunction.
Fig. 205 Display: underinflation warning
Fig. 206 Display: System malfunction
Using the ABS sensors, the tire pressure moni­
toring system compares the tire tread circum­ ference and vibration characteristics of the in­
dividual tires. If the pressure decreases in one
or more tires, this is indicated in the instru­
ment cluster with a warning symbol

message

The tire pressure monitoring system must be
reset via MMI each time the pressures are ad­

placing a tire on your vehicle

an authorized Audi dealer or authorized repair
facility to have the malfunction corrected.
_& 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. In­
flate the tire pressure to the proper pres­
sure as indicated on the vehicle's tire
pressure label<=:>
page 247 . Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability.
- The driver is responsible for maintaining
the correct tire pressures. You must check the tire pressures regularly.

A WARNING
Im proper use of the vehicle jack can cause
serious personal injuries .
- Never use the screw driver hex head to
tighten w heel bolts, since the bolts can­
not attain the necessary tightening tor­
que if you use the hex head, potentially
causing an accident .
- The factory-supplied jack is intended on­
ly for your vehicle model. Under no cir­
cumstances should it be used to lift

Using the spare tire (compact spare tire )
The compact spare tire is only intended for
emergenc ies until you can reach a repair shop.
Replace it as quickly as poss ible with a s tand­
a rd wheel and tire.
There are some restrictions on the use of the
compact spare t ire. Th e compact spare t ire
has been des igned specifically fo r your type of
ve hicle . It must not be swapped with a com­
pact spare ti re from another type of vehicle .
Snow chains
For technica l reasons, the use of snow chains
on the compact spare tire is
not p ermitt ed .
If you do have to dr ive with snow cha ins and a
front tire fails, mo unt the spare wheel w ith
tire instead of a rear t ire. I nstall the snow chains on the rear tire and use it to rep
lace
the defective front tire.
A WARNING
-- Never use the spare t ire if it is damaged
or if it is worn down to the tread wear in­
d icators.
- If the spare tire is more than 6 years old, use it only in an emergency and with ex­
treme caution and careful driv ing.
- The spare tire is intended only for tem­ porary and short-term use. It s hou ld be
replaced as soo n as poss ible with the
normal wheel and tire.
- After mounting t he compact spare tire,
the t ire pressure must be checked as
soon as possible . The tire pressure of the
compact spare t ire must be 4. 2 ba r; oth­
erwise, you risk having an a cc iden t.
- Do not dr ive faste r th an

- For technica l reasons, the use of tire

If i t is necessary to drive with tir e c hains,
the spare wheel must be mounted on the
