Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of veh icle control. It works
only when the eng ine is running. ESC detects
certain difficult driv ing situations, including
when the vehicle is beginning to spin (yaw) out of cont ro l and he lps you to get the vehicle
back under control by select ively b rak ing the
wheels, and/or red ucing engine power and
p roviding steering assistance to help hold the
ve hicle on the driver's intended course . The in­
dicator light
DJ in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
phys ics. It will not a lways be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situat ions where there is a
sudden change in the coefficient of fr iction of
the road surface. When there is a sect io n of
d ry road that is s udden ly cove red with water,
slush o r snow, ESC canno t perform the same
way it would on the dry su rface.
If the vehicle
hydroplanes (rides on a c ush ion of water in­
stead of the road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because con-
Int ellig ent technolog y 171
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
D uring fast corner ing, particular ly on wind ing
roads, ESC cannot always deal as effectively
with difficult dr iv ing s ituations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic and weather conditions . ESC can­
not override the vehicle's physical lim its, in­
crease the availab le tract ion, or keep a veh icle
o n the road if road departu re is a result of
driver ina ttent io n. Instead , ESC imp roves the
poss ibility of keep ing the vehicle under con­
trol and on the road during extreme maneu­
vers by using the driver's steering i nputs to
help keep the vehicle go ing in the intended di­
rect ion. If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC is switched on all the time. In certain sit­
uat ions when you need less traction, you can
switch off ASR by pressing the butto n
[ill
~ page 173, fig. 166 or~ page 173,
fig. 167. Be sure to sw itch ASR on aga in when
you no lo nger need less traction.
The following systems are integrated in the
ESC:
Anti-lock bra king sy stem (ABS )
ABS prevents the whee ls from locking up
when brak ing. T he vehicle can st ill be steered
even dur ing hard braking. App ly steady pres­
su re to the brake peda l. Do not pump the ped­
al. A pulsing in the brake pedal ind icates that
the system is helping you to brake the veh icle .
Brake assi st system
The brake ass ist system can decrease braking
distance. It increases brak ing power when the
drive r presses the brake peda l quickly in emer­
gency s ituations. You must press and hold the
brake pedal unti l the s ituation is over. In
vehicles with adaptive c ruise control*, the
brake assis t system is more sensitive if the
•
•

172 Intelligent technology
distance detected to the vehicle ahead is too
smal l.
Anti-slip regulation (ASR )
ASR reduces eng ine power when the drive
wheels begin to spin and adapts the fo rce to
the road condit ions. This makes it eas ier to
start, accelerate and drive up hills .
Electronic differential lock (EDL )
The EDL brakes wheels that are spinn ing and
transfers the d rive powe r to the other wheels.
This f unct ion is available up to abo ut 60 mph
(100 km/h) .
In extreme cases, ED L automat ica lly switches
off to help keep the brake on the braked whee l
from ove rheating. EDL wi ll switch on aga in a u­
tomatically when conditions have returned to
norma l.
Steering recommendation
The ESC helps to stabilize the ve hicle by
changing the steering to rque.
In vehicles with dynam ic steeri ng*, ESC also
helps to stabilize the stee ring in critical s itua­
tions.
Select ive wheel torque control
Selective whee l 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 mo re prec ise d riving in curves. The
appl icable system may no t activate when d riv­
i ng in wet or snowy condi tions.
A WARNING
- The ESC and its integrated systems can ­
not overcome the laws of physics. This is especia
lly important on slippery o r wet
roads. If the systems begin acting to sta­
bilize your veh icle, you should immedi­
ately change your speed to match the
road and traffic cond itions. Do not let
the increased safety provided by these
systems tempt you to take risks. Do ing
so will in crease the r is k of a loss of vehi­
cle control, collision and serious person al
in juries.
- Always adap t your speed to road, traffi c
and weather conditions . The risk of los ­
ing control of the vehicle increases when
driving too fast, especially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead. The ESC and its integrated sys­
tems cannot a lways p revent collisions -
there is still a risk of acc idents!
- Always accelerate with special care on
even, smooth s urfaces such as those that
are wet or covered with ice and snow.
T he drive w heels can spin even w ith
these assistance sys tems that cannot al­
ways he lp to re duce the risk of loss of ve ­
h icle control.
(D Tips
- ABS and ASR o nly wo rk correctly when
a ll four wheels are equipped wi th iden ti­
c al tires. D ifferen t tire sizes can lead to a
reduction in engine powe r.
- Yo u may hear noises when the systems
descr ibed are workin g.

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
Accessory weight
means the combined weight (in
excess of those standard items
which may be replaced) of auto­ matic transmission, power
steering, power brakes, power
windows, power seats , radio,
and heater, to the extent that
these items are available as fac­
tory-installed equipment (whether installed or not).
Aspect ratio
means the ratio of the height to
the width of the tire in percent.
Numbers of 55 or lower indi­
cate a low sidewall for im­
proved steering response and
better overall handling on dry
pavement.

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.

_& WARNING
- If the t ire pressure indicator appea rs in
the instrument cl uster display, one or
more of you r tires is significantly under­

and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the t ires and the ir pressures . In­
flate the tire pressure to the proper pres­ sure as indicated on the vehicle's t ire
pressure label
c::> page 217. Driving o n a
signific antly under-inflated tire ca uses
the tire to overhea t and can lead to tire
f ailure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability.
- The driver is responsible for maintaining
the correct tire pressures . You must
check the t ire pressures regular ly.
- Under certain cond itions (such as a spor ­
ty driving style, w inter condit ions or un­
