The ESC helps to stabilize the vehicle by
changing the steering torque.
Selective wheel torqu e control
Select ive wheel torque control is used when
driving on curves . The front wheel on the in­
side of the curve or both wheels on the inside
of the curve are braked selective ly as needed.
This a llows more precise driving in curves.
Automatic post -collisi on brakin g system
The "Automatic post-collision braking system "
can help to reduce the risk of slidi ng and of
other coll is ions afte r an accident. I f the airbag
con tro l modu le detects a collision above ace r­
tain vehicle speed, the vehicle is braked by the
ESC.
The vehicle does not brake automatically if:
- the driver presses the accelerator pedal, or
- the braking force generated by the pressed
brake pedal is greater than the braking force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle
electrical system are not functioning.
A WARNING
-The ESC and its integrated systems can­
not overcome the limits posed by natura l
physical laws. This is especially impor ­
tant on s lippery or wet roads. If the sys-
Switching on/off
Sm art Te chnol og y 189
terns beg in acting to stabilize your vehi­
cle, you should immediately alter your
speed to match the road and traffic con­
ditions . Do not let the increased safety
provided tempt you into taking r isks .
This could increase your risk of a co lli­
SIOn.
- Please note the r isk of a coll is ion increas­
es when driving fast, especially through
curves and on slippery or wet roads, and
when dr iv ing too close to objects ahead.
The ESC and its integrated systems can ­
not a lways prevent collisions -there is
still a risk of accidents!
- Press the accelerator pedal caref ully
when acce lerating on even, slippery sur­
faces such as ice and snow. The drive
wheels can spin even when these control systems are installed and this can affect
driving stability and increase the r isk of a
coll is ion.
@ Tips
-ABS and ASR only function correctly
when all four wheels are equipped w ith
identical tires. Different t ire sizes can
lead to a reduct ion in engine power.
- You may hear noises when the systems
descr ibed are working.
- If the
Bl or [I] indicator light appears,
there may be a malfunction

The ESC is designed to funct ion in levels . De­
pend ing on the level that is selected, the sta­
bilization funct ion of the ESC is lim ited or
swi tched off . The amoun t of stabilization con­
trol wi ll differ depending on the level.
In the follow ing unusual situations it may
make sense to switch the ESC sport mode on
to allow the wheels to sp in:
- Rocking the vehicle to free it when it is stuck
- Driving in deep snow or on loose ground

256 Tires and wheels
loss of control, crashes and serious per­
sona l injuries . Have worn or damaged tires
replaced immediate ly.
- Winter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed .
- Never drive faster than the speed for
which the winter or other tires installed
on your vehicle are rated.
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac­
celeration of the winter tires and all-wheel
drive tempt you into taking extra risks. Al­
ways remember:
- When braking, an all-wheel drive vehicle
handles in the same way as a front drive
vehicle .
- Drive carefully and reduce your speed on
icy and slippery roads, even winter tires
cannot help under black ice conditions.
@) For the sake of the environment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow chains may be fitted only to the front
wheels, and only to certain tire sizes. Ask your
authorized Audi dealer on which tire sizes
snow chains can be used.
If 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 0.53 inch
(13.5 mm), including the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
q 0 . For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
A WARNING
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different
sizes . Always make sure to follow the in­
structions provided by the snow chain
manufacturer.
- When driving with snow chains never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
@ Note
-Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily .
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered. Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
@ Tips
Where snow chains are mandatory on cer­
tain roads, this normally also applies to
vehicles with all-wheel drive .
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of wheel bolts is matched to the
factory installed rims. If different rims are fit­
ted, the correct wheel bolts with the right
length and correct ly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly . .,..

In certain circumstances, you may not use
wheel bo lts from a different vehicle -
even if it
i s the same mode l
Qpage 284.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
control, a collision and ser ious personal in­
jury .
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­
erly t ightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can
become loose w hile d riving if greased or
o iled,
even if tightened to the spec ified
torq ue.
- Only use wheel bo lts that belong to the
rim being ins talled.
- Never use different whee ls bolts on your
vehicle .
- Always maintain the correct tightening
torque fo r the wheel bolts to reduce the
risk of a wheel loss. If the tigh teni ng 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 ca n be­
come loose .
(D Note
The specified torque for the wheel bo lts is
90 ft lb (120 Nm) w ith a tolerance of
± 7,4 ft lb(± 10 Nm). Torque whee l bolts
diagonally. After changing a wheel, the
torque must be checked as soon as possi­
b le with a torque wrench -prefe rably by an
author ized Audi dealer or qualified wo rk­
shop.
Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio tires . These tires have been thorough ly
tested and been selected spec ifically for your
model for the ir superb performance, road feel
Tire s an d wheel s 257
and handling under a variety o f driving condi ­
tions. Ask your authorized A udi dealer for
more details .
T he low aspec t ratio of these tires is ind icate d
by a numera l of
55 or le ss in the tire's size
designation. The numera l represents the ratio
of the t ire's sidewa ll height in relation to its
tread width expressed in percentage.
Conven­
tiona l tires have a he ight/w idth rat io of 60 or
more .
The performance of low-a spect-ratio tire s is
particularl y sens it iv e to improper inflation
pressure. It is therefore important that low
a spect ratio tir es are inflated to the specified
pre ssure and that the inflation pr essure i s
regularly checked and ma intain ed . Tire pr es­
s ure s should be checked at lea st on ce a
month and alway s bef ore a long trip
~ page 240 , Checking tire pressure .
A Word about Low Aspect Ratio and High
Performance Ti res
Hig h pe rformance tires are des igned for bet­
ter performance and handling in warm cli­
mates. When driving in cold, snowy or icy
weather, you sho uld equ ip your vehicle w it h
four all-season or winter tires, which
offer
better traction under those condit ions. We
suggest you use the Audi recommended win­
te r or a ll-season tires specified for you r Audi.
High performance tires a lso have a lower as ­
pect ratio that aids performance and han­
dling . Driving over rough or damaged road
surfaces, as well as debr is, cu rbs and other
obstacles can cause serious damage to
whee ls, tires, vehicle body, and suspens ion
parts . B e carefu l to avo id road hazards and re­
du ce your speed , espec ia lly if your vehicle is
equipped wi th low prof ile tires .
Please a lso remember when making your se­
lection that, wh ile these tires deliver respon­
s ive handling, t hey m ay ride less comfo rtably
and make more noise than o thers . Finally,
these tires may wear more quickly than other
c h oices.

doing the following .
• Always store the vehicle tool kit, the jack*
and the replaced tir e in the luggage com­
partment ~
page 132 .
• Check the tire pressure on the spare wheel
i mmediately after mount ing it.
• As soon as possible, have the
tightening
torques
on a ll wheel bo lts checked with a
torque wrench. The correct tightening tor­
que is 90 ft lb (120 Nm).
• Have the flat tire
replaced as soon as poss i­
ble.
(D Tips
- If you notice that the wheel bolts a re
corroded and difficult to turn while
chang ing a tire, they should be rep laced
before you check the tightening torque.
- Drive at reduced speed until you have the
tightening torques checked.
- After changing a whee l, the tire pressure
in all four tires must be checked/correct­
ed and the tire pressure monitoring indi­
cator must be stored in the MMI

268 What do I do no w?
-Pull the reversible blade from the screw ­
driver before you use the hexagonal
socket in the handle to t urn the whee l
bo lts.
- When mounting tires with
unid ire ctional
t re ad design
make s ure the tread pat­
tern is pointed the right way
¢ page 268.
-The wheel bolts should be clean and easy
to turn. Check for d irt and corrosion on
the mat ing su rfaces of both the whee l
and the hub. Remove all dirt from these
surfaces before remount ing the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the right direction.
Using a spare tire with a tread pattern
int ended fo r use in a specific dir ection
When us ing a spare tire w ith a tread pattern
i ntended for use in a specific direction, please
note t he following:
- The direction of rotation is marked by an ar ­
row on the side of the tire .
-If the spare t ire has to be installed in the in­
correct direction, use the spare tire only
temporarily since the t ire will not be able to
achieve its optimum perfo rma nce character­
ist ics with rega rd to aquaplaning, noise and
wea r.
- We recommend that you pay particular at­
tent ion to this fact du ring wet weat her and
that you adjust your speed to match road
condit ions .
- Replace the fla t tire w ith a new one and
have it ins talled on your veh icle as soon as
possible to restore the handling advantages
of a unidirectiona l tire .
Notes on wheel changing
