Steering recommendation
The ESC helps to stabilize the veh icle by changing
the steering torque.
Selective wheel torque control
Selective wheel torque control is used when driv
i n g on curves . The front wheel on the inside of
the c urve or both wheels on the inside of the
curve are braked selectively as needed. This al
lows more precise driving in curves.
Automatic post-collision braking system
The "Automatic post-collision brak ing system"
can help to reduce the r isk of slid ing and of other
coll is ions after an accident . If the airbag control
module detects a collision above a certain 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 electri
cal system are not functioning.
A WARNING
- The ESC and its integrated systems cannot
overcome the limits posed by natural physi-
Switching on and off
cal laws. This is especially important on slip
pery or wet roads. If the systems beg in act
ing to stabilize your vehicle, you should im
mediately alter your speed to match the
road and traffic conditions. Do not let the
increased safety provided tempt you into
taking risks. This could increase your risk of
a collision.
- Please note the risk of a collision increases
when dr iv in g 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 cannot always pre
vent collisions -there is still a risk of acci
dents!
- Press the accelerator peda l carefully when
accelerating on even, slippery surfaces such
as ice and snow. The drive wheels can spin
even when these control systems are instal
led and this can affect driving stability and
increase the risk of a collision .
@ Tips
-ABS and ASR only function correctly when
all four wheels are equipped with identical
tires. Different tire sizes can lead to a reduc
tion in engine power.
- You may hear noises when the systems de
scribed are working.
£SC turns on automatically when you start the engine .

The ESC is designed to function in levels. Depend
i ng on the level that is selected, the stabilization
function of the ESC is limited or switched off. The amount of stabilization control will differ de
pending on the level.
The following examples are unusual situations
where it may make sense to switch offroad mode
on to allow the wheels to spin:
- Rocking the vehicle to free it when it is stuck
- Dr iving in deep snow or on loose ground

New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au
thorized Audi Service Facility.
These facilities have the proper knowledge and are equipped with
the required tools and replace
ment parts.
.,.New tires do not yet have the
optimum adhesion properties. Drive carefully and at moderate
speeds for the first 350 miles (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
wheels .
198
.,.Do not replace tires individually.
At least replace both tires on the
same axle at the same time.
.,.Audi recommends that you use
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 ¢
,&.
.,. If you would like to equip your
vehicle with a tire/rim combina
tion that is different from what
was installed at the factory, con
sult with an authorized Audi dealer or authorized Audi Service
Facility before making a pur
chase ¢&, .
If the spare tire is different 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.
On
all wheel drive vehicles, all
four wheels 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 reason, in case of emergency, only
use a spare tire that has the same
circumference as the regular
tires.
&_ 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.
Wheels
-Only use tires that are more
than 6 years old when abso 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.

Wheels
-Overloading can lead to loss of vehicle control and increase
the risk of an accident. Read and follow the important safe
ty precautions inc:::> page 203,
Tires and vehicle load limits.
-The tire must flex more if the tire pressure is too low or if
the vehicle speed or load are
too high . This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con
trol.

A WARNING
Using incorrect snow chains or installing snow

Snow chains can damage the r ims/wheel cov

Use coated snow chains .
Low aspect ratio tires
Your Audi is facto ry-equipped with low aspect ra
tio ti res. These t ires have been tho rough ly tested
and been se lected specifically for yo ur model fo r
thei r superb per formance, road feel and handling
under a variety of driving conditions. Ask your au
thorized Audi dealer for more details .
The low aspect ratio of these t ires is indica ted by
a numera l of
55 or les s in the tire's size designa
tion. The numeral represents the ratio of the
tire's sidewall height i n relation to its tread width
expressed in percentage. Conventional tires have
a height/w idth ratio of 60 or more.
Th e performance of low-aspect- ratio tire s is par
ticularly sensit ive to improper inflation pre s·
sure . It is therefore important that low aspect
ratio tires are inflated to the specified pressure
and that the inflation pre ssure is regul arly
ch ecked and ma intained . Tire pre ssure s should
be checked at least once a month and a lways
before a long tr ip

What you can do to avoid tire and rim
damage
L ow aspect rat io tires can be damaged more easi
ly by impact wi th pot holes, c urbs, gull ies or
r idges on the ro ad, p articul arly if the tire is un
de rinflated.
I n o rder to minimize the occurrence of impact
damage to the t ires of your ve hicl e, we recom-
Wh eel s
mend that you observe the following preca u
tions:
- Always ma in tain recommended inflat io n pres
sures. Check yo ur tire pressure every 2,0 00
m iles (3,000 km) and add air if necessary .
- Dr ive c arefully on roads w it h potholes, deep
gullies or ridges . The impac t from dr iving
through or over such obstacles can damage
your tires. Impact with a curb may a lso cause
damage to your tires.
- After any impact, immediate ly inspect your
tires or have them inspected by the nearest au
thorized 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 not always
easy to see . Damage can lead to loss of air and
underinflation, wh ich could even tually cause
tire fa ilure. If yo u believe that a tire may have
been damaged, replace the tire as soon as pos
sib le.
- These tires may wear more quickly tha n others .
- Please also remember that, while these tires
delive r responsive ha nd ling, they may ride less
comfortably a nd make mo re noise than other
choi ces.
