Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
Event Data Recorder
This vehicle is equipped wi th an Event Data Re­
corde r (E DR). The main purpose of an EDR is to
reco rd, in ce rtain c rash o r ne ar cras h-like sit ua ­
tions, such as an a irbag deployment or hitting a
road obstacle , data that will assis t in understand ­
ing how a vehicle's systems performed. The EDR
is designed to record data re lated to veh icle dy­
namics and safety systems for a short period of
time, typically 30 seconds or less. The EDR in this
vehicle is designed to record such data as:
- How vario us systems in you r vehicle were oper­
at ing;
- Whether or not the driver and passenger safety
gi belts were buckled/fastened; ......
~ - How fa r (if at all) the driver was depressing the
N ~ acce le rato r and/o r bra ke peda l; and,
0 LL 00
Intellig ent Technology
- How fast the vehicle was traveling.
T hese data can help p rovide a bette r understand­
i ng of the circumst ances in w hich cras hes and in­
ju ries occu r. NOTE: EDR data ar e recorded by your
vehicle on ly if a non -trivial crash s ituation occurs;
no data are reco rded by the ED R under norma l
driv ing cond itions and no persona l data (e .g .,
name, gender, age, and crash location) are re ­
corded. However, other parties, such as law en­
forcement, could comb ine the EDR data with the
type of personally identify ing data rout inely ac­
quired d uring a c rash investigation .
To read data recorded by an EDR, special equ ip­
ment is required, and access to the vehicle or the
E DR is needed . In addition to the ve hicle manu­
factu rer, other part ies, such as law e nfo rcement,
t h at have the special equipment, can rea d the in ­
f o rmat io n if they have a ccess to the vehicle or the
ED R.
Some sta te laws restrict the retrieval o r down­
l oad ing of data sto red by ED Rs ins talled in a veh i­
cl e for the exp ress p urpose of re triev ing da ta af­
ter an acci dent or crash event without the own­
er 's consent .
Audi will not a ccess the EDR and/or sim ila r data
o r g ive it to o thers -
- unless the veh icle owne r (or lessee if the vehi­
cle has been leased) ag rees; 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 jud ic ia l
discovery process.
-Aud i may a lso use the data fo r research abo ut
veh icle operation and safety perfo rmance or
prov ide the data to a third party for research
purposes witho ut ide ntify ing the specific veh i­
cle or i nfo rmat ion about the ident ity of its own­

Fa ults in the brake system
If yo u should notice a sudden increase i n brake
pedal travel, then one of the two brake circuits
may have failed
¢ .&. .
Low brake fluid level
Malf unct ions can occur in the bra ke system if the
b rake fl uid leve l is too low. The brake fluid level

Bra ke booste r
The brake booster increases the pressure that
you generate with the brake pedal.
It works on ly
when the engine is run ning
.¢ .&.
Bra ke lining we ar status
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the open ings in the wheel. If necessary,
the wheel may be removed for this inspection
¢ page 228, Replacing wheels.
A WARNING
- New bra ke pads don't have the best stop­
ping power and must be "bro ken- in" dur ing
the init ia l 250 m iles (400 kilometers). Yo u
can compensate for th is by press ing the
brake pedal more firmly. This a lso applies
later when new pads are installed.
- Yo u should perfo rm braking maneuvers for
the p urpose of clean ing the brake system
only if road conditions permit. Other road
users must not be put at risk -you may
cause an accident!
- Before descending a steep grade, reduce
speed and shift t ransm iss ion into a lower
gear or lowe r driving range. Do not ride the
brakes or hold the pedal down too long or
too often. This could ca use the brakes to get
hot and diminish brak ing efficie ncy.
- Do not "r ide t he b rakes" by resting your foot
on the pe dal when yo u do not inten d to
bra ke. This may cause the bra kes to over­
heat, premat ure wear and increased stop ­
ping distance.
- Under certa in climatic and operating condi­
tio ns such as passing thro ugh water, driving
in heavy rain or after washing the vehicle,
Intellig ent Technology
the effectiveness o f the brakes can be re­
duced. In winter, ice can accum ulate on the
brake pads, lin ings, d iscs and drums . Care­
fu lly apply brakes for a test . Brakes will dry
and ice coat ings will be cleaned off after a
few ca refu l brake applications .
- Driving for an extended period of t ime on
salt-covered roads without usi ng your
b rakes can also affect braking eff iciency.
Clea n off acc umul ated salt coat ing from
b rake discs an d pa ds w ith a few careful
b rake appli cat ions .
- I f you d amage the front spoile r, or if you in­
s t all a different spoiler, be s ure the a ir flow
to the front brakes is not obstruc ted. Other­
wise the brake system could overheat reduc­ ing the effectiveness of t he ent ire bra ke sys­
tem.
- Fai lure of one brake circuit w ill impa ir the
braking capability resulting in an increased
stopping distance . Avoid driving the vehicle
and have it towed to the nearest authorized
Aud i dealer or qualified workshop.
- Never let the vehicle roll to a stop with the
engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed cons iderab ly
ha rder to make up fo r the lack of booste r
assis tance .

Winter tires
When dr iving in the winter, yo ur vehicle with all­
whee l dr ive has a n advantage, even with regu la r
t ir es. In w inte r road cond it ions i t may be advisa­
ble to mo unt win ter tires (o r all-se ason tires) for

Off-Road driving?
Your Aud i does not have enough g ro und clear­
ance to be used as an off -road vehicle. It is there ­
fore best to avoid roug h tracks and uneven ter­
rain as much as possible. A lso refer to
¢ page 175.
_&. WARNING
Always adjust you r driving to road and t raff ic
conditions. Do not let the extra safety afford­
ed by all-wheel drive tempt you into tak ing
extra risks.
-Although the all-whee l dr ive is very effec­
t ive, a lways remember that bra king capac ity
is limited by tire traction . Yo u should there­
fore not d rive a t exc ess ive speeds on icy or
slippery road su rfaces.
- On wet ro ad surfaces, be caref ul not to drive
too f ast be cause the fro nt wheels co uld be­
gin to slide on top of the w ater ( aquaplan ­
ing). If this sho uld o ccu r, you w ill have no
warning from a sud den increase in eng ine
speed as with a front-whee l dr ive vehicle .
Always drive at speeds wh ich are su ited to
the road cond it ions -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution of
electrical energy and thus optimizes the availa­
bility of electrical energy for s tarting the engine.
If a veh icle wit h a conventional energy system is
not driven for a long per iod of t ime, the battery is
d ischa rged by idling current consumers (e.g. im­
mo bilizer). In cert ain cir cums tan ces it c an result
i n there be ing insuff ic ient ene rgy available to
start the engine.
I ntell igen t energy management in your veh icle
h andles the distr ib ution of ele ct ric al ene rgy.
S tarting ab ility is mar ked ly imp roved an d the l ife
of the batte ry is extended.
B asically, e nergy management consis ts of
bat­
tery diagno sis, idling curr ent management
and
dynamic energy management .
Intelligent Technology
Battery diagnosis
Battery diagnos is con tinuously dete rmi nes the
state o f the bat tery . Sensors determine battery
vo ltage, battery c urrent and batte ry tempera­
tu re. This determines t he current state of charge
and the power of the battery.
Idling current management
Id ling cur rent management reduces ene rgy con­
s u mption whi le the vehicle is standing . With the
ignition switched off, it contro ls the energy sup­
ply to the vario us electrical components . Data
from battery d iagnosis is cons idered.
Depend ing on the ba ttery's s tate of charge, indi ­
vidual consumers are gradually turned off to pre­
vent excess ive discharge of t he battery and thus
mainta in starting capab ility.
Dynamic energy management
While t he vehi cle is being d riven, dynami c energy
management dis trib utes the energy generate d
according to the needs of the individual compo­
nents. It regulates consumption, so that more
electrical e nergy is not being used than is being
generated and ensures an opt imal state of
charge for the battery .
(i) Tips
-But even ene rgy management cannot neg­
ate the lim its of physics. Consider that the
powe r and life of a battery are lim ited.
- If starting ab ility is threatened, the indica ­
to r li ght (•) appears¢
page 14.
What you should know
The highest priority is given to maintaining start­
ing capability.
The battery is severe ly taxed in short-distance
driv ing, in city traffic and dur ing the cold time of
year. Abundant e lectrica l energy is required, but
o n ly a little is generated. It is also c ritical if the
engi ne is not running and electrical components
are tu rned on . In this instance energy is being
co nsumed bu t no ne is being ge nerated. .,,.

Breaking in
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the first 600 miles (1 ,000 kilometer s):
"' Do not use full throttle .
"' Do not drive at engine speeds that are more
than
2/3 of the max imum permitted RPM .
From 600 to 1,000 miles (1 ,000 to 1 ,500
kilometers):
"' Speeds can gradually be increased to the maxi­
mum pe rm issib le road or engine speed .
During and after break-in pe riod
"' Do not rev the engine up to high speeds when it
is cold. This applies whether the transmission is
in N (Neutral) or in gear .
After the break-in period
"'Do not exceed maximum engine speed under
any c ircumstances.
"'U pshift into the next higher gear

During the first few hours of driving, the eng ine's
internal friction is higher than later when all the
mov ing parts have been broken in . How well this
b reak-in process is done depends to a considera­
b le exte nt on the way the veh icle is d rive n during
t he first 1,000 miles (1,500 kilometers).
(D Note
Extremely high eng ine speeds a re au toma ti­
cally reduced. However, these rpm limits are
programme d for a n engine well run-in, not a
new engine.
@) For the sake of the environment
D o not dr ive with u nnecessari ly high eng in e
spee ds -ups hifting ea rly saves fuel, reduces
noise and pro tec ts the envi ronme nt .
Driving and the envir onment
New tires
If your vehicle is runn ing on new tires, d rive very
car efu lly fo r the firs t 35 0 miles (500 kilometers)
a ft er fit ting.
New tires tend to be slippe ry and must a lso
be "bro ken-in". Be sure to remembe r th is dur­
i ng the fi rst 350 m iles (500 kilometers).
Brake gent ly. Avoid following closely behind
other vehicles or other s ituations that m ight
r equire sudden, hard b raking.
Avoid damaging the
vehicle
When yo u are dr iv ing o n poor roa ds, or over
cur bs, stee p ramps, e tc., ma ke cert ain that low­
ly ing parts s uch a s spo ile rs a nd exh aust sy stem
parts do no t bottom o ut and get dama ged.
T his is espec ially true for ve hicles with low-s lung

vehicles.
Driving through water on
roads
Note t he following to avoi d ve hicle damage w hen
driv ing through water, for examp le on flooded
roads:
- The water must not be any hig her t han the bot ­
tom of the vehicle body.
- Do not dr ive faste r than walk ing speed.
A WARNING

Afte r driv ing th ro ugh water, m ud, slush, etc .,
the brakes may be slow to take effect beca use
of wet brake rotors and pa ds. Dry the brakes
f irst by braking carefully to restore the full

Driving and th e en vironm ent
(D Tips
- Check the depth of the water before driving
through it .
- Do not stop the veh icle, drive in reverse or
switch the engine
off when driving through
water.
- Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your veh icle to drive
through safely.
- Avoid driving through salt water because it
can cause corrosion.
Catalytic converter
It is very important that your emission control
system (catalytic converter) is functioning prop­ erly to ensure that your vehicle is running in an
environmentally sound manner .
~ Always use lead-free gasoline ¢ page 188,
Fuel supply .
~ Never run the tank down a ll the way to empty .
~ Never put too much motor oil in your engine
¢ page 19 7, 9::?l Adding engine oil .
~ Never try to push- or tow-start you r vehicle.
The cata lytic converter is an efficient "clean-up"
dev ice bu ilt into the exha ust system of the vehi­
cle. The cata lytic conve rter burns many of the
pollutants in the exhaust gas before they are re ­
leased into the atmosphere.
The exclusive use of unleaded fue l is critica lly im­
portant for the l ife of the catalytic conve rter and
p roper functioning of the engine.
A WARNING ,..____ -
- The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exha ust tail pipes once they
have become hot. This could result in burns.
- Do not park or ope rate t he vehicle in areas
where the hot exha ust system may come in
contact with dry grass, br ush, fue l spill or
other mater ial which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust mani-
176
fold, exha ust pipes, cata lytic conve rter or
heat shields. D uring driving, the substance
used for undercoat ing could overheat and
cause a f ire.
Cl) Note
- Be aware that just one tank f illing wit h
leaded fu e l w ill already seriously degrade
the performance of the catalytic converter.
- Do not exceed the correct engine oil leve l
¢page 197.
-Do not drive until the fue l tank becomes
completely empty. The engine could mis­
fire. Unbu rned fue l cou ld also get into the
exhaust system and this could cause the
catalytic converter to overheat.
- Do not turn off the ign ition while the vehicle
is moving .
- Do not continue to operate your vehicle un­
der these conditions, as otherw ise fuel can
reac h the catalytic converter. T his could re­
sult in overheat ing of the converter, requir­
ing its replacement.
- T o ass ure eff icient operat ion of the Emis­
sion Contro l System:
- Have you r vehicle maintained properly and
i n accordance wit h the service recommen­
dations in your Warranty
& Ma intenance
booklet.
- Lack of proper ma intenance as well as im­
p roper use of the veh icle will impa ir the
function of the emission control system
and could lead to damage.
(® For the sake of the environment
Even when the Emiss ion Control System is op­
erating properly, t he exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. Th is depends on the sulfur
content of the fuel being used. Us ing a d iffer­
ent brand of fuel may help, or fi lli ng the tank
wi th lead-free super g rade gasoline.
Shutting down vehicle

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation .
If you plan to tow a trailer, please remember that
the additional load will affect durability, econo­
my and performance.
Trailer towing not only places more stress on the
vehicle, it also calls for more concentration from
the driver.
For this reason, always follow the operating and
driving instructions provided and use common
sense.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your vehicle and trailer and must be mounted
securely on the vehicle's chassis at a technically
sound
location . Use only a trailer hitch with a re­
movable ball mount . Always check with the trail­
er hitch manufacturer to make sure that you are
using the correct hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that it
does not interfere with the impact -absorbing
bumper system . No modifications should be
made to the vehicle exhaust and brake systems .
From time to time, check that all hitch mounting
bo lts remain securely fastened.
When you are not towing a trailer,
remove the
tra iler hitch ball mount . This prevents the hitch
from causing damage shou ld your vehicle be
struck from beh ind ¢
,&. .
Trailer brakes
If your trailer is equipped with a braking system,
gi check to be sure that it conforms to all regula-......
~ tions . N ...... 0

LL 00
Trailer towing
The trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system ¢.&. .
Safety chains
Always use safety chains between your vehicle
and the trailer.
Trailer lights
T ra iler lights must meet all regulations . Be sure
to check w ith your author ized Audi dealer for cor­
rect wiring, switches, and relays.
Mirrors
If you are unable to see the traffic behind you us­
ing the regular outside mirrors, then you
must in­
stall extended mirrors. It is important that you
always have clear vision to the rear.
,8. WARNING
-If a tra iler has electr ical brakes please note
that these bra kes are not activated by the
factory-fitted control unit -risk of accident!
- After removing the trailer hitch, do not
store it in your vehicle. In case of sudden
braking, the hitch could fly forward and in­
jure you or your passengers.
Operating instructions
Maximum trailer weight
A trailer for your vehicle is limited to a typical
class 1 or class 2 trailer.
Trailer load distribution
Be sure the load in the trailer is held sec ure ly in
place to prevent it from shifting forward, back­
ward or sideways.
Never allow a passenger to ride in a trailer¢.&.
in Driving instructions on page 180.
Engine cooling system
Towing a trailer makes the engine work harder . It
is important that the cooling system's perform ­
ance is up to the additional load . Make sure that
the cool ing system has enough fluid. .,..
