steering wheel will be easy to move. Re
initia lization might be necessary if the steer
ing whee l was moved hard to the left and
right while the vehicle was not moving. The
d isplay goes out as soon as in itia lizat ion is
comp lete.
A WARNING
Have the dynamic steering* system ma l
function repaired as soon as poss ible by an
authori zed A udi dealer or any qualified
workshop -risk of accident!
- If the . or

on for a short t ime, yo u may continue
drivi ng.
- The dynamic steering * stability systems
are not available in the event of a system
malfunction.

Driving with your
quattro ®
Applies to vehicles: with all-wheel drive
With all-wheel drive, all four wheels are driv
en.
General information
W ith all-whee l drive, power is distribute d to
a ll fo ur whee ls. This happens automat ica lly
d epending on your dr iving sty le and the road
conditions at the t ime. See also¢
page 185 .
A cen ter different ial d istr ib ut es the dr iv ing
power var iably to the front and rear axle. It
wo rks together with se lective whee l torque
control, which activates when driving throug h
curves ¢
page 186. With the sport differen
tial*, power distribution to the rear wheels is
variable and can be adjusted with Audi drive se lect ¢
page 109 .
The all-wheel drive concept is designed for
h igh engine power . Your vehicle is exception
ally powerful and has exce llent dr iving charac
terist ics bot h under normal driving conditions and on snow and
ice . Always read and follow
safety precautio ns ¢ &. .
Winter tires
When driving in t he win ter, yo ur vehicle wi th
all-wheel d rive h as an adv antage, eve n w it h
r egular tires. In wi nte r road conditions it may
be advisable to mount winter tires (or all -sea
son tires) for improved driveability and brak
i ng : these tires must be mounted on
all fou r
wheels . See also ¢ page 246, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this no rma lly also app lies to ve hicles
with all-wheel drive¢
page 247, Snow
chains .
Replacing wheels/tires
Vehicles wi th a ll-wheel drive m ust always
have ti res of t he same s ize. A lso avoi d tires
with differe nt t read depths . For detai ls see
page ¢
page 242, New tires and replacing
tires and wheels.
Off-Road dr iving?
You r A ud i does no t have e nough gro und clea r
ance to be used as an off -road vehicle .
It is
t h e refore best to avoid roug h tracks and u n
even te rrain as much as possib le . Also refer to
¢ page 193.
A WARNING
Always ad just your dr iv ing to road and traf
f ic conditions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking ext ra risks .
-Al though the a ll-wheel drive is ve ry ef
fective, always remember that braking capacity is lim ited by tire t raction. You
s hould t herefore no t drive at ex cessive
speeds on i cy or slippe ry road surfa ces.
- On wet road surfa ces, be careful not to
d rive too fast because the fr on t whee ls
could begin to slide on top of the water
(aquaplaning) . If thi s should occur, you

Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv
ing style.

Tread Wear Indicator (TWI)
The origina l tires on your veh icle have
1/16 in ch (1.6 mm) high "wear ind icators"

ing on the make, there will be six to eight of
them evenly p laced around the t ire . Marks on
the t ire s idewall (for example "TWI" or other
symbols) indicate the positions of the tread
wear ind icators . Worn t ires must be replaced.
Different fig ures may apply in other countries

Tir e pressure
Incorrect tire pressure causes premat ure wear
and can cause sudden tire blow-out . For th is
reason, tire pressure must be checked at least
once a month
r::!;> page 23 7.
Dri ving sty le
Driving fast around curves , heavy acceleration
and hard braking increase tire wear. Tires and wheels 241
Rotating tires for more even wear
For all four tires on your ve
hicl e to have the
same service life, we recomme nd that the
front and rear tires are rotated according to
the tire manufacturer 's suggested tire rota
tion inte rvals. Please remember the follow
ing :
- Tire rotation intervals may differ from the
veh icle service inte rva ls o utlined in your
Ma intenance and Warranty Booklet.
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points ; therefore, we recommend that you
follow the tire manufactu rer 's suggested
tire rotation intervals .
- Vehicles w ith front-wheel dr ive exper ience
more tread wear on the front wheels com
pared to all w heel drive (quattro ®).
- Please rotate tires as shown
r::!;> fig. 179.
-Extra care must be taken when rotat ing di-
rection-specific tires
r::!;> page 258 .
Wheel balancing
The wheels on new veh icles are balanced .
However, various situations during everyday
driving can cause them to become unba l
anced, resulting in vibrat ions you can usually
feel through the steer ing wheel.
Unbalanced wheels must be rebalanced to
avoid excessive wear on steering, s uspension
and t ires. A whee l must also be reba lanced
when a new tire is insta lled.
Inco rrect wheel alignment
Incorrect wheel alignment can cause exces
sive tire wear, impair ing the safety of the vehi
cle . If tires show excessive wear, have the
whee l alignment checked by an authori zed
Audi dealer or qualified workshop.
All wheel drive
Vehicles wi th quattro ® must a lways have tires
of the same size, construction and tread type. For details see
