Brake lining w ear sta tus
Brake lining we ar may be che cked by visual in
spection of the condition of the brake pads
through the openings in the whee l. If neces
sary, the wheel may be remove d for this in
spection
c> page 244, Changing a wheel.
.&_ WARNING
- New brake pads do n't have the best sto p
ping power and must be "broken-in" dur
ing the init ial 100 to 1 50 m iles (150 to
200 k ilometers) of normal city driving.
T he break-in period can be considerably
longer for veh icles with ceram ic br ake ro
tors*. You can compensate for this by pressing the brake pedal more firmly.
T his also applies later when new pads are
installed .
- You should perform braking maneuvers
for the purpose of cleaning the brake
system on ly if road condit ions permit.
Other road users must not be put at r isk -
you may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmiss ion into a lower
gear or lower driving range. Do not ride
the brakes or hold the pedal down too
long or too ofte n. This cou ld cause the
brakes to get hot and d imin ish b raking
efficiency.
- Do not "r ide the brakes" by resting your
foot on the pedal when you do not inte nd
t o brake. Th is may cause the b rakes to
overheat, prema ture wear and inc reased
stopping distance .
- Under certa in climat ic and operating
conditions such as passing through wa
ter, driving in heavy rain or after wash ing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Carefully apply brakes
for a test. Brakes will dry and ice coat ings will be cleaned off after a few ca re
ful brake applications.
- Driv ing fo r an extended pe riod of time on
salt-covered roads w ithout using you r
Intellig ent technolog y 175
brakes can a lso affect braking efficiency .
Clean off accum ulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you
install a different spoiler , be sure the air
f low to the front brakes is not obstruct
ed. Otherw ise the brake system could
overheat reducing t he effectiveness of
the entire brake system.
- Failure of one b rake circuit will impa ir
the braking capab ility result ing in an in
creased s topping distance. Avoid driving
the vehicle and have it towed to the near
est a utho rized Audi dea le r or q ualified
workshop.
- Never let the vehi cle roll to a stop with
the engine shut off.
- If the b ra ke booste r is no t working, the
brake peda l must be p ressed considera
b ly harder to make up for the lack of
booster assistance .

Driving with your
quattro
-
With all-wheel drive, all four wheels are driv
en.
General information
W ith all-whee l drive , power is distributed to
a ll four w heels . This happens automatically
depending on your dr iving sty le and the road
conditions at the t ime. See a lso
c::> page 171.
A center different ial d istr ibutes the dr iv ing
power var iably to the front and rear axle.
It
wo rks together wi th se lective wheel torque control, which activates when driving thro
ugh
c u rves
c::> page 172. With the sport differen
t ia l*, power distr ibut ion to the rear wheels is
variable and can be adjusted w ith drive se lect
c::> page 102.
The all-whee l drive concept is designed for
high eng ine power. Your veh icle is except ion
ally powerful and has excellent driving charac
teristics both under normal driv ing cond itions
and on snow and ice . Always read and follow
safety precaut ions
c::> ,& .
Winter tir es
When d riving in the winter, yo ur vehicle with
all-wheel drive has an advantage, even with regular tires. In winter road conditions it may
be advisable to mount winter tires (or all -sea
son tires) for improved dr iveability and brak
ing : these tires must be mounted on
a ll four
wh eels.
See also c::> page 236, Winter tires.
Tire ch ains
Where tire chains are mandatory on cer tain
roads, this normally also applies to vehicles
with all-wheel drive c::> page 23 7, Snow
chains .
Replacing whee ls / tire s
Vehicles with all-wheel drive must always
have tires of the same s ize . A lso avoid tires
with different tread depths. For deta ils see
page
c::> page 230, New tires and replacing
tires and wheels.
Off-Road dr iving ?
Your Audi does not have enough ground clear
ance to be used as an off -road vehicle. It is
therefore best to avoid roug h tracks a nd un
even terra in as much as poss ib le . Also refer to
c::> page 179.
.&_ WARNING
A lways adj ust yo ur dr iv ing to road and t ra f
f ic conditions . Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks.
-Although the a ll-wheel d rive is very ef
fective, always remember that braking
212 Tires and wheels
-If you notice unusual vibra
tion or if the vehicle pulls to
one side when driving, al
ways stop as soon as it is
safe to do so and check the
wheels and tires for dam
age.
0 Note
-Please note that summer and winter tires are de
signed for the conditions
that are typical in those sea
sons. Audi recommends us
ing winter tires during the
winter months. Low tem peratures significantly de
crease the elasticity of
summer tires, which affects
traction and braking ability. If summer tires are used
in
very cold temperatures, cracks can form on the tread
bars, resulting in perma
nent tire damage that can
cause loud driving noise and
unbalanced tires. Audi is not
responsible for this type of
damage.
-Burnished, polished or chromed rims must not be used in winter road condi
tions. The surface of the
rims does not have suffi
cient corrosion protection
for this and could be perma
nently damaged by road salt
or similar substances.
Glossary of tire and loading terminology

wear on steering, suspension and tires. A wheel must also be
rebalanced when a new tire is
installed.
Incorrect wheel alignment
Incorrect wheel alignment can
cause excessive tire wear, im
pairing the safety of the vehi
cle. If tires show excessive
wear, have the wheel alignment checked by an authorized Audi
dealer or qualified workshop.
All wheel drive
Vehicles with quattro must al
ways have tires of the same
size, construction and tread
type. For details see
¢page 176.
A WARNING
Sudden tire failure can lead
to loss of control, a crash and serious personal injury!
-Never drive a vehicle when the tread on any tire is worn down to the wear indica
tors.
-Worn tires are a safety haz
ard, they do not grip well on
wet roads and increase your risk of "hydroplaning" and
loss of control.
Tires and wheels 229
-Always keep chemicals that can cause tire damage, such
as grease, oil, gasoline and
brake fluid away from tires.
-Tires age even if they are not being used and can fail
suddenly, especially at high speeds. Tires that are more
than 6 years old can only be used in an emergency and
then with special care and
at lower speeds.
-Never mount used tires on your vehicle if you are not sure of their "previous histo
ry." Old used tires may have
been damaged even though
the damage cannot be seen
that can lead to sudden tire
failure and loss of vehicle
control.
