cause pressing the accelerator pedal over­
rides the cruise contro l system .
- If a brake system ma lfunction such as over­
heating occurs when the cruise control sys­
tem is sw itched on, the braking function in
the system may be switched off . The rest of
the cruise control system functions remain act ive as long as
the @jll)~i~ (USA models) /

Intelligent Technology
Intelligent Technology Electronic stabilization
control (ESC)
Description
Elect ronic stabili zation control ( ESC) suppo rts
driver safety. It red uces the risk of slipping and
improves dr iving stabi lity. ESC detects crit ica l sit­
uations such as the vehicle overstee ring and un­
dersteeri ng or the w heels are sp inning. The vehi­
cle is stabilized by app lying the brakes or reduc ­
i n g e ngine torque . When the ESC engages, the
liJ indicato r light bli nks in t he instr ument clus­
t er.
The fo llow ing systems are in tegrated in the ESC:
Anti-lock braking system (ABS)
ABS p reve nts the whee ls from lock ing whe n brak ­
ing. The vehicle can st ill be steered even d uring
hard brak ing. Apply steady press ure to the bra ke
pedal. Do not pump the pedal. A puls ing in t he
b rake pedal indicates that the system is act ing to
s tabili ze the vehicle .
Brake assist system
The brake assist system can decrease brak ing dis­
tance . It inc reases brak ing power when the d river
presses the brake pedal q uick ly in eme rgency sit­
uations . You must press and hold t he b rake pedal
until the dangerous si tuatio n is ove r.
Anti-slip regulation (ASR)
ASR red uces eng ine power when the d rive wheels
begin sp inning a nd adapts the force to the road
conditions . This makes it easie r to start, acceler­
ate and dr ive u p hill s.
Electronic differential lock (EDL)
E DL applies the brakes to a wheel that sta rts
spi nning and t ransfe rs the d rive power to the
other driving wheels. This f unction is not availa­
b le at higher speeds.
In extreme cases, EDL automatically sw itches off
to keep the brake on the b raked wheel from over­
heati ng. The vehicle is st ill work ing correctly. EDL
86
will swi tc h on again automatically when condi ­
tions have retu rned to normal.
Power steering
The ESC can also support veh icle stab ility
t hr ough stee rin g.
Selective wheel torque control
Se lective wheel to rque con trol is used when d riv­
i ng on curves . The front whee l on the ins ide of
t h e curve or bo th whee ls on the i nside of th e
cu rve are braked se lective ly as needed. This al­
l ows mo re pre cise dr iving in curves .
_&. WARNING
-The E SC and i ts in teg ra ted systems cannot
overcome the lim its imposed by natura l
phys ica l laws. This is es pec ially important
on s lippery or wet roa ds.
If the systems be­
gin acting to stabilize yo ur vehicle, you
should immediately a lter your speed to
match the road and traffic conditions. Do
no t le t the inc reased safety p rovi ded tempt
you into taking risks. This could increase
y o ur r is k of a c oll is ion.
- Please note the r is k of a coll is ion increases

it s i ntegrated systems cannot a lways pre ­
vent co llisions
-there is st ill a risk of acci­
dents!
- Press the accelerator peda l caref ully when
accelerating on even, slippery sur faces such
as ice and snow. The drive wheels can spin
even when these control systems a re instal­
led and this can affect driving stability and
increase the risk of a collision.
(0 Tips
- The ABS and ASR only funct ion correctly
when a ll four wheels have a sim ila r wear

Brakes
New brake pads
New brake pads do not achieve their full braking
effect d uring the first 250 mi (400 km) . They
must be "broken in" first . Howeve r, you can com­
pensate fo r th e slig htly reduced b raking force by
pressing fi rm ly on t he b rake ped al. Avo id heavy
bra king d uring the brea k-i n pe riod .

Intelligent Technology
Wear
Brake pad wear depends largely on the way the
vehicle is driven and on operating conditions.
This is especially true if you are driving frequently
in the city and on curves or with a sporty driving
style.
Operating noise
Noises may occur when braking depending on the
speed, braking force and outside conditions such
as temperature and humidity.
Wet conditions or road salt
I n certain situations, for example after dr iving
through water, in heavy ra in or after washing
your car, the braking effect may be reduced due
to moisture or ice on the brake rotors and brake
pads . The brakes must be "dried" first with a few
careful brake applications.
At higher speeds and with the windshie ld wipers
turned on, the brake pads press against the brake
rotors for a short amount of time . This action,
which is not felt by the driver, happens at regular
intervals and ensures a better reaction time for
the brakes in wet weather .
The braking effect can also be reduced if you are
driving on sa lted roads and you do not apply the
brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first when the brakes are applied.
Corrosion
Leaving the vehicle parked for long periods of
time, low mi leage and avoiding heavy braking
can contribute to corrosion on the brake rotors
and to dirty brake pads.
If you usually avoid heavy braking or if there is
corrosion present, occasional heavy braking at
h igh speeds is recommended to clean the brake
rotors and
pads¢ &.
Brake system malfunction
If you notice that the brake pedal travel has sud ­
denly increased, then a brake circuit in the dual­
circuit brake system may have malfunctioned. Drive to an authorized Aud i dea ler or authorized
Aud i Serv ice Facility immediately to have the
88
problem corrected. On the way there, drive with
reduced speed and keep in mind that you will
need a longer distance to stop and you will need
to press the brake pedal harder.
Low brake fluid level
When the brake fluid level is low, malfunctions in
t h e brake system may occur . The brake fluid leve l
is electronically monitored .
Brake booster
The brake booster amplifies the pressure you ap­
ply to the brake pedal.
& WARNING
- New brake pads do not achieve their full
braking effect during the first 250 mi
-
(400 km). They must be "broken in" first .
However, you can compensate for the
slightly reduced braking force by pressing
firm ly on the brake pedal. Avoid heavy brak­
ing during the break-in period.
- On ly app ly the brakes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en­
danger other road users . This increases the
r is k of an accident.
- On steep slopes, reduce the speed and se­
lect a lower gea r or lower selector leve r po­
sition. Drive as lit tl e as possible while press­
ing the brake pedal and avo id putting yo ur
left foot on the brake pedal while driv ing .
This could ca use the brakes to overheat and
impair the efficiency of th e brakes.
- Do not let the brakes "grind" by always
keeping your foot on the brake pedal. This
can cause the brakes to overheat, increase
wear and increase braking distance unneces­
sarily.
- Certain weather and operating conditions such as driving through water, dr iv in g in
heavy rain or driv ing after wash ing your ve­
h icle can impair the effectiveness of the
brakes. In the winter, ice may build up on
the brake pads, rotors and drums. Check
these compon ents by braking carefully. Ap­
plying the brakes carefully several times
dries the brakes and removes ice build-up.

Cl 00 .-< N r-­N .-< 0 r-­Vl 00
-The efficiency of the brakes can also be im­
paired by driving for long stretches on roads
covered with salt without using the brakes .
You can remove salt deposits from the
brake rotors and pads by carefully applying
the brakes severa l t imes .
- If the front spoiler is damaged or you install
another spoiler, make sure the front wheel
brakes are vent ilated proper ly . Otherwise,
the b rake system could overheat, w hich re­
duces the ir effectiveness.
- Failure of a brake c ircuit impa irs b raking
perfo rman ce , which increases brak ing dis ­
tan ce. Avoid d riving the vehicle and have it
towed it to the nearest authorized Audi
dealer or authorized Audi Service Facility .
- Never let the vehicle roll while t he engine is
stopped because this increases the risk of an
accident.
- If the brake booster is not working, you will
have to press much harder on the brake
peda l to compensate for the lack of the
booster.
@ Note
- Never let the brakes "rub" by pressing the
pedal light ly when braking is not actually
necessary. This causes the brakes to over­
heat and increases braking d istance and
causes wear.
- Before driving downhi ll a long distance on a
steep h ill, decrease your speed and select a
lower gear. This makes use of the engine
braking effect and relieves the brakes . If
you need to brake additionally, brake in in­
tervals and not conti nuous ly .
0) Tips
- If the brake booster is not working, you
must press the brake pedal with much more
fo rce t han normal.
- If you retrofit your vehicle with a front spoil­
er, whee l covers o r similar items, make sure
t h at the a ir flow to the front whee ls is not
i nte rru pted. Ot herw ise the brake system
ca n become too ho t.

Important safety instructions
A WARNING
Alw ays ma ke sure that t he knee ai rbag can in ­
flate without interferen ce. Obje cts between
yourse lf and the airbag can increase the risk
of injury in an accident by interfering with the
182
way the airbag dep loys o r by being pushed in ­
to you as the airbag dep loys.
- No persons (chi ldren) o r anima ls should ride
in the footwell in front of the passenger
seat.
If the airbag deploys, this can resu lt in
serious or fatal injuries.
- No objects of any kind should be carried in the footwell area in front of the dr iver's or
passenger's seat . Bu lky objects (shopping
bags, for examp le) can hamper or prevent
proper dep loyment of the a irbag. Sma ll ob­
jects ca n be thrown th ro ugh t he ve hicle if
the airbag deploys a nd injur e you or your
p a sse ngers.
Pedal area
Pedals
The pedals must always be free to move and
must never be interfered with by a floor mat or
any other object.
Make sure that all pedals move free ly without in ­
terference and t hat nothing prevents them from
returning to their orig inal positions .
Only use floor mats t hat leave the pedal area free
and can be secured with floor mat fasteners.
If a bra ke circuit fails , in creased bra ke pedal trav ­
el is req uired to b ring the vehicle to a fu ll stop.
A WARNING
Pedals that cannot move freely can cause loss
of vehicle contro l and increase the risk of se ri­
ous injury .
- Never p lace any objects in the driver's foot ­
we ll. An object could get into the peda l area
and interfere with pedal funct ion. In case of
sudden b raking or an acc ident, you would
not be able to brake or acce lerate!
- Always make sure that nothing can fall or move into the driver's footwel l.
