186 Intelligent technology
ESC includes and/or works together with the
anti-lock brake system (ABS), brake assist sys ­
tem, anti-slip regulation (ASR) , e lectronic dif­
ferential lock (EDL), dynamic steering" and
e lectronic interaxle differentia l lock* /selective
wheel torque control* . ESC is switched on all
the t ime. I n certa in s ituations whe n you need
l ess t raction, you can switch
off ASR by p ress­
i ng the bu tto n
[ru ¢ page 187, fig. 161 or
¢ page 187, fig. 162. Be sure to sw itch ASR
on aga in when yo u no longer need less t rac­
tion .
Anti -lock braking system (ABS)
ABS prevents the wheels from locking up
when braki ng. The veh icle can still be steered
even d uring h ard br aking. Apply ste ady p res ­
sure to the brake pedal. Do no t pump the ped­
a l. A pulsing in the brake peda l indicates t hat
the system is he lping yo u to b rake the vehicle .
Brake assist system
The brake assis t system can decrease b ra ki ng
d ista nce. It incre ases braking power w hen the
d river p resses the brake pedal q uic kl y in eme r­
gency situations . You must p ress and hold the
b rake peda l until the situation is over. In
vehicles w ith adapt ive cru ise contro l", the
brake assist system is more sensit ive if the
d ista nce detected to t he vehicle a head is too
small.
Anti-slip regulation (ASR)
ASR reduces engine 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 differenti al lock (EDL )
The ED L brakes wheels that are spinn ing and
transfers the drive power to the other drive
wheel or whee ls if t he vehicle is equipped with
all-w heel drive*. This function is available up
to abo ut 60 mph (100 km/h).
In extreme cases, EDL automat ica lly switches
off to help keep the bra ke on the braked whee l
from overheating. EDL wi ll switch on again au-tomat
ica lly when conditions have ret urned to
no rma l.
Dynamic steering*
On vehicles wi th dynam ic steering*, ESC he lps
st abiliz e the steer ing in cr itical situ ations.
Electronic interaxle differential lock* /
selective wheel torque control*
T he elec troni c int eraxle differentia l lock (front
whee l dr ive) o r th e se lec tive whee l torque
control (all-whee l dr ive) oper ates when dr iv ­
ing t hro ugh curves. The front w heel on the in ­
side of the c urve or both whee ls on the inside
of the c urve are b raked se lectively as needed.
This m inimizes sliding in the front wheels and
allows for more precise driving through
curves . The applicable system may not acti­
vate when dr iving in wet o r snowy cond itions.
A WARNING
- ESC, ABS, ASR, EDL dynam ic steering*
an d the ele ct roni c interaxle differential
lo ck* /se lective whee l torque con trol *
fu nction canno t over come the laws of
p hys ics. Th is is especially important on
slippe ry or wet roads . If the systems be­
g in acting to stabilize yo ur vehicle, you
should immediately change yo ur speed
to match the road and traffic conditions. Do not let the increased safety provided
by these systems tem pt you to ta ke risks.
Doing so will increase the risk of a loss of
veh icle cont ro l, col lision and ser ious per­
sonal injur ies.
- Always ada pt your speed to road, traffi c
a nd wea ther condi tions. The risk of los-
ing con trol of the vehicle increases when
d riving too fast, es pec ia lly through
curves and o n slippe ry or wet roads, an d
when dr iv ing too close to vehicles up
ahead. ESC, ABS, the brake ass ist sys­
tem, ASR, EDL dynam ic steer ing* and the
e lectronic inte raxle differentia l lock*/se­
lec tive whee l to rque control* func tion
cannot prevent collisions.
-

200 kilometers) of normal city driving.
You can compensate for this by press ing
the brake pedal more firm ly. This also
applies later when new pads are instal­
led .
- You should perform brak ing maneuvers
for the purpose of clean ing the brake
system only if road cond it 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 lowe r
gear or lowe r driving range. Do not ride
the brakes or hold the pedal down too long or too often . This cou ld cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by resting your
foot on the pedal when yo u do not intend
to brake. Th is may cause the brakes to
overheat, premature wear and increased
stopp ing distance.
- Under certain climat ic and operating
condit ions such as passing through wa­
ter, driving in heavy rain or after wash ing
the vehicle, the effect iveness of the
brakes can be reduced. In winter, ice ca n
a ccumulate on the brake pads, linings,
dis cs and d rums. Carefully apply brakes
f or 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 ex tended period of time on
salt-covered roads without using your
brakes can also affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads w ith a few caref ul
brake applicat ions.
- If you damage the front spoiler, or if you install a different spoiler, be sure the air
flow to the front brakes is not obstruct­
ed . Otherwise the brake system co uld
overheat reducing the effectiveness of
t h e ent ire brake system.
- Failur e of one bra ke c ircuit will impair
t h e braking capability resulting in an in­
cr eased stop ping distan ce. Avoid driv ing
the vehicle and have it towed to t he near-
Int ellig ent technolog y 189
est a uthorized Audi dea ler or q ualified
workshop.
- Never let the ve hicle roll to a stop with
the engine shut off.
- If the brake booster is not working, for
examp le when towing you r vehicle, or
because the brake booster has somehow
been damaged, the bra ke pedal must be
pressed considerably harder to make up
for the lack of booster assistance .

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
