- If a tether or other strap is used to attach a
child restraint to the front passenger seat,
make sure that it is not so tight, that it
causes the weight-sens ing mat to measure
more weight than is actually on the seat .
- The heavier weight registered can make the

Intelligent Technology Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
E ve nt Dat a Record er
This vehicle is equipped wi th an Event Data Re
corder (EDR) . The main purpose of an EDR is to
record, in certain crash or near crash-like situa
tions, such as an a irbag deployment or hitting a
road obstacle, data that will assist in understand
ing how a vehicle's systems performed. The EDR
is designed to record data related to vehicle dy
namics and safety systems for a short period of
time, typically 30 seconds or less. The EDR in this
ve hicle is designed to reco rd such data as:
- How various systems in your vehicle were oper
at ing;
- Whether or not the driver and passenger safety
belts were buckled/fastened;
- How far (if at all) the dr iver was depressing the
accelerator and/or brake pedal; and,
- How fast the vehicle was traveling.
These data can he lp provide a better understand
ing of the c ircumstances in which crashes and in
juries occur. NOTE: EDR data are recorded by your
veh icle only if a non-trivia l crash situation occurs;
no data are recorded by the EDR under normal
driving conditions and no personal data (e .g.,
name, gender, age, and crash location) are re
corded. However, other parties, such as law en
forcement, cou ld combine the EDR data w ith the
type of personally identifying data routine ly ac
quired during a crash investigation.
To read data recorded by an EDR, specia l equip
ment is req uired, a nd access to the ve hicle or the
E DR is needed. In add it ion to the vehicle manu
facturer, other parties, such as law enforcement,
that have the specia l equipment, can read the in
formation if they have access to the vehicle or the
EDR .
Some state laws restrict the retr ieval or down
l oading of data stored by ED Rs insta lled in a vehi
cle for the express purpose of retrieving data af-
Intellig ent Technology
ter an accident or crash event without the own
er's consent.
Audi will not ac cess the EDR and/or sim ilar data
o r give it to others -
- unless the vehicle owne r (or lessee if the vehi
cle has been leased) agrees; o r
- upon the official request by the police; or
- upon the order of a court of law or a govern-
ment agency; or
- for the defense of a lawsuit through the judic ial
discovery process.
- Aud i may a lso use the data for research about
veh icle operation and safety performance or
prov ide the data to a third party for research
purposes without identify ing the specific veh i
cle or info rmat io n about the ident ity of its own
er or lessee and only afte r the reco rded veh icle
data has been accessed.
Vehicle control modules
Your vehicle is also equ ipped w ith a number of
electronic control modules for va rious vehicle
systems, such as engine management, emiss io n
contro l, airbags, and s afety be lts.
These electronic control modules record data dur ing norma l vehicle operation that may be
needed by trained tech nicians for diagnost ic and
r epa ir purposes. The re cording capab il ity of these
modules is lim ited to data (no sound is record
ed). Only a sma ll amount of data is actua lly re
corded over a very limited period of time, or stor
ed when a system fault is detected by a control
module . Some of the data stored may relate to
vehicle speed, direction, or braking, as well as re
straint system use and performance in the event
of a crash. Stored data can also on ly be read a nd
down loaded w ith specia l equipment that is d i
rectly connected to the vehicle.

Electronic Stabilization
Control (ESC)
Description
E SC helps to imp rove ro a d hold ing and vehicle
dynamics to help reduce the probab ility of skid
d ing and loss of veh icle control. It works only
when the engine is runn ing . ESC detects certain
d iffic ult dr iving situat io ns, including when the
ve hicl e is begin ning to spin (yaw) o ut of contro l
a nd h elps you to ge t the veh icle b ack u nder con
trol by se lectively braking the wheels, and/or re
ducing engine powe r and providing steering as
sistance to help hold the vehicle on the driver's intended course. The indicator light
GI in the in
strument cluster blinks when ESC is tak ing action
t o he lp you contro l the vehicle.
ESC has lim itations. It is important to remembe r
that ESC cannot overcome the laws of physics. It
will not a lways be able to help out under all con
d itions you may come up aga inst . For example,
ESC may not always be able to help you master
situations where there is a sudde n change in the
coeff ic ie nt of fr iction of the road surface. W hen
there is a se ction of dry road tha t is sudde nly cov
e red with w ater, slush o r sn ow , ESC c annot pe r
form the same way i t wou ld on the dry s urface. If
the vehicle hydrop lanes (rides on a cushion of wa
ter instead of t he road su rface), ESC wi ll not be
ab le to he lp you stee r the veh icle because contact
with the pavement has been inter rupted and the
ve hicle cannot be b raked or steered . Dur ing fast
cornering, part icu larly on w inding roads, ESC
can not always deal as effect ive ly w it h difficult
d riving situat ions than a t lowe r speeds . When
towi ng a trail er, ES C i s not able to help you re
g ai n con trol as it would if you we re not towing a
tra ile r.
A lways ad just yo ur speed and driving sty le to
road , tr affic and weathe r cond itions. ESC canno t
override the vehicle's phys ical lim its, incre ase the
170
available tract ion, or keep a vehicle on the road i f
r oad depa rt u re is a res ult of d river inattention .
Instead, ESC improves the poss ib ili ty of keeping
the ve hicle unde r contro l and on the road d uring
extreme maneuvers by using the driver's steer ing
i nputs to help keep the vehicle going in the in
tended direction . If you are traveli ng at a speed
t h at causes you to r un off the road before ESC
can p rovide any assista nce, you may not exper i
ence the benefi ts of ESC.
ESC is switched on all the time. In certa in s itua
tions when you need less tract ion, yo u can sw itch
off AS R by press ing the button
I!] c:> page 171,
fig. 152 or c> page 171 , fig. 153. Be s ure to
swi tch ASR on again w hen you no longer need
l ess trac tion.
The following systems a re in tegrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up when
braki ng . The vehicle can st ill be steered even d ur
i ng hard b raking . Apply steady p ressure to the
brake peda l. Do not pump the pedal. A p uls ing in
t h e b rake pedal indica tes th at th e system is help
i ng yo u to b rake t he ve hicle.
Brake assist system
The bra ke assist system can decrease braking dis
ta nce. It increases b raking powe r whe n the dr iver
presses t he br ake peda l quickly i n emergency sit
u at io ns. Yo u must pre ss and ho ld the bra ke peda l
u nt il t he s itu at ion is ove r. In vehicles wi th adap
tive cr uise con trol *, the brake assist sys tem is
more sensitive if t he di stance detected to the ve
h icle ahead is too sma ll.
Anti-slip regulation (ASR)
ASR redu ces engine powe r whe n the dr ive whee ls
begin to spi n and a da pts the fo rce to the road
con ditio ns. Thi s ma kes it easier to s tart, acce le r
ate and d rive up hills .
Electronic differential lock (EDL)
The ED L brakes w heels that are spi nning and
t ra nsfe rs the dr ive power to the ot her dr ive
whee l or w heels if the vehicle is equ ipped with
a ll- wheel drive*. This function is not avai lab le at
h ighe r speeds. .,..

In extreme cases, EDL automatically switches off
to help keep the brake on the braked wheel from
overheating. EDL w ill switch on aga in automati
cally when conditions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque .
In vehicles with dynamic steering*, ESC also
helps to stabilize the steering in critical situa
tions.
Electronic interaxle differential lock*/
selective wheel torque control*
The electronic interaxle differential lock (front
wheel drive) or the selective wheel torque control
(all wheel drive) operates when driving through
curves . The front wheel on the inside of the curve
or both wheels on the inside of the curve are
braked selectively as needed. This allows more
precise driving in curves. The applicable system
may not activate when driving in wet or snowy
conditions .
_&, WARNING
- The ESC and its integrated systems cannot
overcome the laws of phys ics. Th is is espe
cially important on slippery or wet roads.
If
the systems begin acting to stabilize your
Switching on /off
Intelligent Technology
veh icle, you should immediately change
your speed to match the road and traffic conditions. Do not let the increased safety
provided by these systems tempt you to
take risks. Doing so will increase the risk of
a loss of vehicle control, collision and seri
ous personal injuries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of losing con
trol of the vehicle increases when driving
too fast, especially through curves and on
slippery or wet roads, and when driving too
close to vehicles up ahead . The ESC and its
integrated systems cannot always prevent
collisions -there is still a risk of accidents!
- Always accelerate with special care on even,
smooth surfaces such as those that are wet
or covered with ice and snow. The drive
wheels can spin even with these assistance systems that cannot always help to reduce
the risk of loss of vehicle control.
{!) Tips
- ABS and ASR only work correctly when all
four wheels are equipped with identical
tires. Different tire sizes can lead to a reduc
tion in engine power.
- You may hear noises when the systems de
scribed are working .
ESC turns on automatically when you start the engine.

The ESC is designed to function in levels. Depend
ing on the level that is selected, the stabilization
function of the ESC is limited or switched off. The

Braking
What affects braking efficiency?
New brake pads
D ur ing the first 250 miles (400 km) , new brake
pads do not possess their full b raking effe ct, they
have to be "b roken in" first ¢,&. . You can com
pensa te for th is slightly reduced b raking power
by p ushing harder on the brake pedal. Avo id
heavy braking loads dur ing the break-in period .
Operating conditions and driving habits
The brakes on today's automobi les are s till sub
je ct to wear, depending large ly on operating con
dit ions and driving habits ¢.&. . On vehi cles that
a re either driven mostly i n stop-and-go city traf
fic or are drive n hard, the b rake pads sho uld be
checked by your authorized A udi dealer more of
ten than specified in the
Wa rrant y & Mainte
nance book let .
Failure to have your brake pads
i nspected can result in reduced brake perform
ance .
On steep slopes, you should use the brak ing ef
fect of the engine . Th is way, you prevent unnec
essary wear on the brake system . If you must use
your brakes, do not ho ld the bra kes down contin
u ously. P ump the bra kes at inte rvals.

Operating noi se
Noises may occur when braking depend ing on the
speed, braking force and outside conditions such
as temperature and humidity.
Eff ect of wat er and road salt
In ce rtain situations, for example after dr iving
through water, in heavy ra in, afte r ove rnig ht con
densat io n 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 applications .
At highe r speeds and with the windsh ie ld wipers
turned on, the brake pads press against the brake rotors for a short amount of time . This occurs at
regular intervals without the driver noticing and
provides for better brake response time under
wet conditions.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road and the brakes are not used . Likewise, you clean
off accumu lated salt coating from brake discs
and pads with a few cautious applications of the
brake ~,&. .
Cor ro sion
There may be a tendency for dirt to b uild up on
the brake pads and corros ion to form on the discs
if the car is not driven regularly or only for short
tr ips with little use of the brakes .
If the brakes are not used frequently, or if corro
sion has formed on the discs, it is adv isable to
clean off the pads and discs by braking firmly a
few t imes from a moderately high speed
c:> ,&. .
Fa ults in the brake sy stem
If you should notice a sudden increase in brake
pedal travel, then one of the two brake circuits
may have failed
c:> ,&. .
Low brak e fluid level
M alfunct ions can occur in the brake system if the
b rake fluid leve l is too low . The brake fluid level
is monitored e lectronically .
Intelligent Technology
Brake booster
The brake boos ter increases the press ure that
you generate with the brake peda l.
It works only
when the eng ine is running

Brake lining wear status
B rake lining wea r may be chec ked by visua l in
spe ct ion of the condi tion of the brake pads
t hr ough the openings in the wheel. If necessary,
the wheel may be removed for this inspection
c:> page 2 26, Replacing wheels .
_8 WARNING "'---
-New brake pads don't have the best stop
ping power and m ust be "broken-in" during
the initial 250 miles (400 kilometers). You can compensate for this by p ressing the
brake pedal more firmly . This also app lies
later when new pads are installed.
-
- You shou ld pe rform braking maneuvers for
the purpose of cleaning the brake system
only i f road condit ions pe rmit . Other road
users m ust not be put at r is k -you may
cause an ac ciden t!
- Before descending a s teep g rade , reduce
speed and sh ift tr ansmi ssion into a lower
gear or lower dr iving range. Do not r ide the
brakes or hold the pedal down too long or
too often. This co uld cause the brakes to get
hot and dimin ish braking eff ic iency.
- Do not "ride the bra kes" by resting your foot
on the pedal when you do not intend to brake. This may cause the brakes to over
heat, premature wear and increased stop
ping distance.
- Unde r ce rtain climatic and operating condi
tions such as passing through water, driving in heavy rain or after wash ing the veh icle,
the effectiveness o f the brakes ca n be re
duced. In winter, ice can accumu late on the
brake pads, lin ings , d is c s and dr ums . Care
fu lly apply br akes for a test. Brakes will dry
and ice coatings will be cleaned off after a
few careful bra ke applications .
- Driving for an extended period of time on
salt -covered roads without using your
brakes can also affect braking eff iciency .
173

Intelligent Technology
Clean off accumulated salt coating from
brake discs and pads with a few caref ul
brake app lications.
- If you damage the front spoiler, or if yo u in
stall a d ifferent spoiler, be sure the air flow
to the front brakes is not obstructed. Other
wise the brake system could overheat reduc
ing the effectiveness of the entire b rake sys
tem.
- Failure of one brake c ircuit will impair the
