A WARNING
You should only resume the stored speed if it
is not too high for existing traffic conditions.
Otherwise you risk an accident .
@ Tips
-If the brakes become too heated whi le driv­

Audi adaptive cruise control
Description
A ppl ies to: ve hicles w ith Audi a daptive cruise co ntrol
F ig. 87 Detection range
The adaptive cruise control system is a combina­
tion of speed and distance regulation .
It assists
the driver by both regulating the speed and
maintaining a distance to the object ahead, with-
90
in the abilities of the system. If the system de­
tects an object, adaptive cruise contro l can brake
and acce lerate your vehicle. This makes driving
more comfortable both on long stretches of
highway and in stop-and-go traffic.
What can adaptive cruise control do?
The adaptive cruise control system uses radar
and a video camera. The radar is subject to desig­
nated system limits
c:> page 91.
On open roads with no traffic , it functions like a
cruise contro l system. The stored speed is main ­
tained. When approaching an object ahead and
the system detects it, the adapt ive cr uise control
system automatically brakes to match that ob­
ject's speed and then maintains the stored dis­
tance . As soon as the system does not detect an
object ahead, adapt ive cruise control acce lerates
up to the stored speed.
Within the limits of the system, adaptive cruise control can brake in stop -and -go traffic until the
vehicle is stat ionary and then begin driving agai n
under certain conditions
c:>page 94, Driving in
stop-and-go traffic.
Which functions can be controlled?
When you switch adapt ive cru ise control on, you
can set the current speed as the "control speed"
c:> page 92, Switching on/off .
When driving, you can stop cruise control
c:> page 94 or change the speed c:> page 94 at

p re se nse front
Fig. 88 Front of vehicle: sensor
The general information applies to adaptive
cruise control* and pre sense front*
i::;, page 97.
The radar sensor area
i::!:> fig. 88 must not be cov­
ered with stickers, deposits or any other obstruc­
tions as it may impair the function of the adap­
tive cruise control and the pre sense front. For in­
formation on cleaning, refer to
c> page 224. The
same applies for any modifications made in the
front area .
The function of the adaptive cruise control sys­
tem and pre sense front is limited in some condi­
tions :
- Objects can only be detected when they are
within the sensor range ¢
page 90, fig. 87.
-The system has a limited ability to detect ob­
jects that are a short distance ahead, off to the side of your vehicle or moving into your lane.
- Objects that are difficult to detect such as mo­
torcycles, vehicles with high ground clearance
or an overhanging load are detected late or not detected at all.
- When driving through curves'=>
page 92.
- With stationary objects ¢
page 92.
A WARNING
Always pay attention to traffic when adaptive
cruise control is switched on and the pre
sense front is active
'=> page 9 7. As the driv­
er, you are still responsible for starting and
for maintaining speed and distance to other objects. The pre sense front is used to assist
you. The driver must always take action to
Assist
avoid a collision. The driver is always responsi­
ble for braking at the correct time.
- Using adaptive cruise control incorrectly can
cause collisions, other accidents and serious
injuries.
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydroplan­
ing). Using the system under these condi­
tions could result in a collision.
- Switch adaptive cruise control off tempora­
rily when driving in turning lanes, on ex­
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the set speed when in these situations.
- The adaptive cruise control system will not
brake by itself if you put your foot on the ac­
celerator pedal. Doing so can override the
speed and distance regulation.
- When approaching stationary objects such
as stopped traffic, adaptive cruise control
will not respond and pre sense front will
have limited function.
- The adaptive cruise control system and pre
sense front do not react to people, animals,
objects crossing the road or oncoming ob­
jects.
- The function of the radar sensors can be af­
fected by reflective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice.
- Always maintain enough distance from
vehicles ahead so that you can still brake
your vehicle safely . The adaptive cruise con­
trol cannot safely slow your vehicle or brake it to a stop if you are driving too close be­
hind a vehicle. Please note that the auto­
matic braking function cannot brake sud­
denly or apply the brakes fully under these
conditions.
- To reduce the risk of unintended actions,
switch the ACC off when you a re not actively
using it.

Electronic stabilization
control (ESC)
Description
The Electronic Stabilization Control (ESC) rein for­
ces driver safety . It reduces the risk of slipping
and improves driving stability. ESC detects crit i­
cal s ituations such as the vehicle oversteering
and understeering or the wheels are spinning.
The vehicle is stabilized by applying the brakes or reducing eng ine torq ue. When the ESC engages,
the
D1 ind icator light blinks in the instrument
cluste r.
The fo llow ing systems are integrated in the ESC :
Ant i-loc k braking system (ABS)
ABS p revents the whee ls from locking whe n brak­
ing. The vehicle can sti ll be steered even during
hard brak ing. Apply steady press ure to the brake
pedal. Do not pump the pedal. A puls ing in t he
b rake pedal indicates that the system is acting to
s tabilize the vehicle .
Brake assist system
The brake assist system can decrease brak ing dis­
tance . It increases braking power when the d river
presses the brake pedal quick ly in emergency sit­
uations . You must press and hold t he b rake pedal
until the dangerous situat io n is over . In veh icles
with adapt ive c ruise control*, the bra ke as sist
sy stem is more sensitive if t he di sta nce detec ted
t o the vehicle ahea d is too sm all.
Anti-slip regulation (ASR)
ASR reduces eng ine power when the drive wheels
beg in sp inning a nd adapts the force to the road
conditions . This makes it easie r to start, acceler­
a te and dr ive u p in clines.
Electronic differential lock (EDL )
The EDL brakes w heels that a re spinning and
transfers the drive power to the other drive
wheel or whee ls if t he ve hicle is equipped with a ll
wheel drive*) . T his funct ion is not av ailable at
h igher speeds.
116 I
n extreme cases, ED L automat ically swi tches off
to keep the brake on the braked whee l from over­
heating. The veh icle is still working correct ly. ED L
will switc h on again automatically when condi­
tions have returned to normal.
Steering recommendation
The ESC he lps to stabili ze the vehicle by cha nging
the steering torque.
Selective wheel torque control
Se lective w hee l to rque cont rol is used when d riv ­
i ng o n curves. The fron t whee l on the inside of
the curve or bo th whee ls on the inside of the
cu rve are braked se lective ly as needed. This al­
l ows mo re precise driving in cu rves.
Automatic post-collision braking system
The "A utomat ic pos t-coll is io n braking sy stem"
c a n hel p to reduce t he risk of sliding and o f othe r
collisions after an accident . If the a irbag cont rol
module detects a collision a bove a certain vehicle
speed, the vehicle is bra ked by the ESC.
The vehicle does not bra ke automatically if:
- the dr ive r presses the acce lerator pedal, or
- the braking force generated by the pressed
brake pedal is grea ter than the braking force
that wo uld be i nitiated by the system, or
- the ESC, the brake system o r the ve hicle elect ri­
cal system are not func tioning .
A WARNING
- The ESC and its integ rated syste ms can not
o vercome the lim its posed by natural physi ­
c a l la ws. Thi s is espe cial ly import ant on sli p­
pe ry o r we t roads. If the systems beg in act ­
ing to stabilize your ve hicle, yo u should im­
mediately a lter your speed to matc h the
road and traffic condit ions. Do not let the
increased safety pr ovided tempt you into
taking risks . This cou ld increase your risk of
a co llision .
- Please note the r isk of a collis ion increases
when dr iv ing fast, especia lly t hrough c urves
and on slippery or wet roads, and when dr iv­
ing too close to objects ahead. The ESC and
i t s in tegr ated systems cannot always .,..

Intelligent Technology
(D Tips
-ESC/ASR cannot be switched off or sport
mode cannot be switched on if the cruise
control system* or the adaptive cruise con­
trol* is switched on.
- Malfunctions in the Audi magnetic ride may make it impossible to switch the ESC/ASR
off or to switch sport mode on.
Brakes
New brake pads
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 com­
pensate for the slightly reduced braking force by
pressing firmly on the brake pedal. Avoid heavy
braking during the break-in period .
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 .
Effect of water and road salt
In certain situations, for example after driving
through water, in heavy rain, after overnight con­ densation or after washing your car, the braking
effect can be reduced by moisture or ice on the
brake rotors and brake pads. The brakes must be
"dried" first with a few careful brake applica­
tions.
At higher speeds and with the windshield 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 facilitates a better reaction time for
the brakes in wet weather .
The braking effect can also be reduced if you are
driving on salted roads and you do not apply the
118
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 mileage and avoiding heavy braking
can contribute to corrosion on the brake rotors
and dirty brake pads.
If you usually avoid heavy braking or if there is
corrosion present, occasional heavy braking at
high speeds is recommended to clean the brake
rotors and pads¢.&. .
Brake system malfunction
if you notice that the brake pedal travel has sud­
denly gotten larger, then a brake circuit may have
failed. Drive to an authorized Audi dealer or au­
thorized Audi Service Facility immediately to have
the problem corrected. On the way there, drive
with reduced speed and keep in mind that a long
braking distance and increased pressure on the
brake pedal will be necessary.
Low brake fluid level
When the brake fluid level is low, malfunctions in
the brake system may occur. The brake fluid level
is electronically monitored.
Brake booster
The brake booster amplifies the pressure you ap­
ply to the brake pedal.
It only works when the en­
gine is running.
A 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
firmly on the brake pedal. Avoid heavy brak­
ing during the break-in period.
- Only apply 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
risk of an accident.

<( co .... N r--­N .... 0 r--­> co
-On steep slopes, reduce the speed and se­
lect a lower gear or lower selector lever po­
sition. Dr ive as little as possible while press­
ing the brake pedal and avoid putt ing your
left foot on the brake pedal while driving.
Th is co uld cause the brakes to overheat and

- Certa in wea ther an d operat ing co ndi tio ns
s u ch as dr iving through wate r, d riving in
heavy ra in or d riving after washing your ve ­
hicle can impair the effectiveness of the
brakes . In the w inte r, ice may b uild up on
the brake pads, rotors and drums. Check
these components by braking ca refu lly . Ap­

-If the front spoiler is damaged or you ins tall
ano ther spoiler, m ake sure the front wheel
bra kes are vent ilated p roper ly. O therwise,
the b rake system could overheat, whic h re ­
duces the ir effectiveness.
- Failure of a brake circuit impai rs b raking
performance, which increases braking dis­
tance . Avoid driving the vehicle . Have it tow ­
ed to the nearest authorized Aud i dealer or
authorized Audi Service Fac ility .
- Never let the vehicle roll while the engine is
stopped because this increases the risk of an
acc ident.
- If the brake booster is not working, you will
have to press m uch ha rder on the brake
peda l to compensate for the lack o f the
booster .
0 Note
-Never let the bra kes " rub" by pressing the
pedal lightly when braking is not really nee-

essary . This causes the b rakes to overheat
and increases braking distance and causes
wear .
- Before driving on a long st retch with steep
slopes, reduce your speed and shift to the
next lower gear Th is makes use of the en­
gine braking effect and relieves the brakes.
If you need to brake additionally, brake in
intervals and not continuously .
(D Tips
-If the brake booster is not work ing, you
must press the brake peda l with much more
force than normal.
- If you retrof it your vehicle with a front spo il­
er, wheel covers or sim ilar items, make sure
that the air flow to the fro nt wheels is not
inter rupted . Otherwise the b rake system
can become too hot.

will also decrease considerably and decrease braking performance.
Therefore, the brake fluid must be changed
every
two years. Always use new brake fluid which con­
forms to Federal Motor Vehicle Standard "FMVSS
116 DO T 4" .
The brake fluid reservoir can be difficult to reach,
therefore, we recommend that you have the
brake fluid changed by your author ized
Audi
dealer. Your dealer has the correct tools, the
right brake fluid and the know-how to do this for
you.
A WARNING
- Brake fluid is poisonous. It must be stored
only in the closed original container out of
the reach of children!
- Brake failure can result from old or inappro­
priate brake fluid . Observe these precau­
tions:
- Use only brake fluid that meets SAE speci­
fication
J 1703 and conforms to Federal
Motor Vehicle Standard 116. Always check
with your authorized Audi dealer to make
sure you are using the correct brake fluid .
The correct type of brake fluid is also indi­
cated on the brake fluid reservoir.
- The brake fluid must be new. Heavy use of
the brakes can cause a vapor lock if the
brake fluid is left in the system too long.
This can seriously affect the efficiency of
the brakes as well as your safety. This
could result in an accident.
(D Note
Brake fluid will damage the paint of your vehi-
cle. ..,.
