also lead to sudden tire fail­ure, including a blowout
and sudden deflation, caus­ ing loss of vehicle control.
-The driver is responsible for the correct tire pressures for
all tires on the vehicle. The
applicable pressure values
are located on a sticker on
the driver's side B-pillar.
-Only when all tires on the vehicle are filled to the cor­
rect pressure, the tire pres­
sure monitoring system can
work correctly.
-The use of incorrect tire
pressure values can lead to
accidents or other damage.
Therefore it is essential that
the driver observe the speci­
fied tire pressure values for
the tires and the correct
pressures for the function of
the tire pressure monitoring
system.
-Always inflate tires to the recommended and correct
tire pressure before driving off.
- Driving with underinflated
tires bend more, letting
them get too hot resulting
in tread separation, sudden tire failure and loss of con­
trol.
-Excessive speed and/over­
loading can cause heat
build-up, sudden tire failure
and loss of control.
-If the tire pressure is too
low or too high, the tires
will wear prematurely and the vehicle will not handle
well.
-If the tire is not flat and you
do not have to change a
wheel immediately, drive at
reduced speed to the near­
est service station to check
the tire pressure and add air
as required.
(D Note
Driving without valve stem
caps can cause damage to
the tire valves . To prevent
this, always make sure that
factory installed valve stem caps on all wheels are secure­ly mounted on the valve.
@ For the sake of the environment
Underinflated tires will also
increase the fuel consump­
tion .

252 Tires and wheels
Tire service life
The service life of tires depends
on a lot of different things in­
cluding proper installation and
balancing, correct tire pressure
and driving style.
Fig. 170 Tire tread: tread wear indi­
cators (TWI)
Fig. 171 Rotating tires for more even
wear
Tread Wear Indicator (TWI)
The original tires on your vehi­
cle have 1/16 inch (1.6 mm)
high "wear indicators"
¢ fig. 170 running across the
tread. Depending on the make,
there will be six to eight of
them evenly placed around the
tire. Marks on the tire sidewall (for example "TWI" or other symbols)
indicate the positions
of the tread wear indicators.
Worn tires must be replaced.
Different figures may apply in
other countries
¢ ..1.. .
Tire pressure
Incorrect tire pressure causes
premature wear and can cause
sudden tire blow-out. For this
reason, tire pressure must be
checked at least once a month
¢page 245.
Driving style
Driving fast around curves,
heavy acceleration and hard
braking increase tire wear.
Rotating tires for more even
wear
For all four tires on your vehicle
to have the same service life,
we recommend that the front and rear tires are rotated ac­
cording to the tire manufactur­
er's suggested tire rotation in­
tervals. Please remember the
following:
-Tire rotation intervals may dif­
fer from the vehicle service in­
tervals outlined in your War­
ranty
& Maintenance booklet. ""

266 Tire s and wheels
& WARNING
-If the tire pressure warning light ti] in
the instrument cluster turns on, the
pressure in one or more tires is too low.
Reduce the vehicle speed immediately
and avoid any hard steering or braking
maneuvers . Stop as soon as possible,
check the t ire and inflate the tire to the
correct pressure, which is specified on
the tire pressu re label on the veh icle
¢ page 240. Driving with a t ire with low
pressure causes the tire to overheat and
can result in failure of the tire . Low pres ­
sure can a lso have a negative effect on
the driving and braking behavior of the
vehicle.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the t ire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor ind i­
cator may be delayed .
- Ask your author ized dealer if run-flat
t ires may be used on your vehicle.
- The tire pressure monitoring system can
also stop work ing when there is an ESC
malfunction.
- Using snow chains may result in a system
malfunction.
- The tires with the identification "AO" or
"RO" ¢ page 254 have been matched
with your Audi tire pressure monitoring
system. We recommend that you use
these tires.
- The tire pressure monitoring system can
only mon itor the t ire pressure of the
driving tires . Check the tire pressure of
the spare wheel in the luggage compart­ ment so that if necessary it is ready for
us e.
-
Storing tire pressures
Applies to vehicles: wit h tire press ure mo nitor ing system
A change in tire pressure or a change in tires
must be stored in the system.
The tire pressure is stored in the MMI.
.. Make sure before storing that the tire pres ­
sures of a ll four tires meet the specified va l­
ues and are adapted to the load. Otherwise
the system could malfunction
¢ page 240.
.. Switch on the ignition.
.. Select: the
I MENU I button >Car > Systems*
control button > Service & control > Tire
pressure monitor > Store tire pre ssure >
Yes, store now.
(D Tips
Do not store the tire pressures if snow
chains are installed. Otherwise the system
could malfunction.

274 What do I do no w?
When removing or installing the wheel,
the rim could hit the brake rotor and dam­
age the rotor. Work carefully and have a
second person help you.
Never use the hexagonal socket in the han ­
dle of the screwdriver to loosen or t ighten
the wheel bolts.
- Pull the reversible b lade from the screw­
driver before yo u use the hexagonal
socket in the handle to turn the whee l
bo lts.
- When mounting tires with
unid irectional
tread design
make sure the tread pat­
tern is pointed the r ight way
¢page 274.
- The wheel bolts should be clea n and easy
to tu rn . Check for d irt and corrosion on
the mat ing su rfaces of both the whee l
and the h ub. Remove a ll dirt from these
su rfaces before remo unti ng the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern p ointed in
the right direction.
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a sp are tire w ith a tread pa tte rn
i nten ded for use in a specific direc tion, p lease
note t he following:
- T he direction of rotation is marked by an a r­
row on the side of the tire.
- If the spare t ire has to be installed in the in­
c orrec t direction, use the spa re tire only
tempor arily si nce the t ire will no t be able to
achieve its op timum performance character­
istics with regard to aquaplaning, noise and
wear .
- We recommend tha t you pay particular a t­
tention to this fact during wet weather and
that you adjust your speed to matc h road
condit ions. -
Replace the flat ti re with a new one and
have it insta lled on your vehicle as soo n as
possible to resto re the hand ling advantages
of a unidirectional tire.
Notes on wheel changing
Please read t he information ¢ page 254, New
tires and replacing tires and wheels
if you a re
going to use a spa re tire which is different
from the t ires on you r vehicle.
After you change a tire:
- Check the tire pre ssure on the spare imme­
diately after installation .
- Have the wheel bolt tightening torque
c hecked with a torque wrench as soon as
possible by your author ized Audi dealer or
a qualified service stat ion.
- With steel and alloy wheel r ims, the wheel
bolts a re co rrectly tightened at a torque of
90 ft lb (120 Nm ).
- If you notice that the wheel bolts are cor ­
roded and difficult to turn while changing
a tire , they should be replaced before you
check the t ightening torque .
- Replace the flat tire w ith a new one and
have it installed on your vehicle as soon as
po ssible . Remount the wh eel cover.
Until then , dr ive with e xtra care and at re­
duced speeds.
A WARNING
= -
- If you are going to equ ip your vehicle
with tires o r rims which differ from those
which were facto ry installed, then be
s ure to read the information¢
page 25 4,
New tires and repla cing tires and
wheels.
- Always m ake s ure the dam age d wheel o r
even a flat tire a nd the jack and tool ki t
are properly secu red in the luggage com­
pa rtment and are not loose in the pas ­
senger compartment.
- In an accident or sudden maneuver they
could fly forwa rd, injuring anyone in the
veh icle.
