A WARNING 1-=
-ESC, ABS, ASR and EDL cannot overcome
the laws of physics. This is espec ially im
portant on slippery or wet roads. If the
systems begin act ing to stab ilize your ve
hicle, you should immediately change
your speed to match the road and traffic conditions. Do not let the increased sa fe
ty provided by these systems tempt you
to take r isks. Doing so will increase the
risk of a loss of vehicle control, collision
and ser ious persona l injuries.
- Always adapt your speed to road, traffic
and weather conditions. The risk of los
ing control of the vehicle increases when
dr iv ing too fast, especially through
curves and on slippery or wet roads, and
w hen driving too close to vehicles up
ahead. ESC, ABS, the b rake assist sys
tem, ASR and EDL cannot prevent co lli
sions.

Brake system
Operating conditions and driving habits
The brakes on today's automobiles are still
subject to wear, depending largely on operat
ing conditions and driving habits
c> Li::,. . On
vehicles that are either driven most ly in stop
and-go city traffic or are dr iven hard, the
brake pads should be checked by your author
ized Audi dealer more often than specified in
the Warranty & Maintenance booklet . Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes, you should use the braking
effect of the engine . This way, you prevent un
necessary wear on the brake system .
If you
must use your brakes, do not hold the brakes
down continuously. Pump the brakes at inter
vals.
Noises may occur when braking depending on
the speed, b raking force and outs ide cond i
tions such as temperature and humidity.
Moisture or road salt
Under certain conditions, for example, when
driv ing through water or very heavy rain, or
even after washing your veh icle, the braking
effect can be reduced due to moisture (or in
freezing conditions ice) on the bra ke pads. A
f ew careful brake applications should dry off
the brake pads or remove any ice coatings.
jll,,
When you are driving at higher speeds wit h
the windshield wipers on, the brake pads will briefly touch the brake d iscs in regular inter
vals so as to improve reaction t ime when brak
ing on wet surfaces. You, the driver, will not
notice anything .
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered
road and the brakes are not used . Here too,
you should clean
off accumulated salt coat ing
from brake discs and pads with a few careful
applications of the brake ¢ & .
Cor ro sion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not dr iven regularly or
only for sho rt trips with little use of the
b rakes .
If the brakes are not used frequently, or if cor rosion has formed on the discs, it is advisable
to clean
off the pads and discs by b rak ing
fi rm ly a few times from a mode rately h igh
speed ¢.& .
Faults in the brake system
If you should notice a sudden increase in
brake peda l travel, t hen one of the two brake
circu its may have failed¢& .
Low brake flu id le vel
Malfunct ions can occur in the brake system if
the brake fl uid level is too low . T he brake fluid
level is monitored electronically .
Brake booste r
The brake booster increases the pressure t hat
you generate w ith the bra ke pedal. It on ly op
erates while the eng ine is running¢ &.

A WARNING
-You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
Othe r road use rs must not be put at risk -
you may ca use an accident!
- Before descend ing a steep grade, reduce
speed a nd s hift transmission into a lower
gea r o r l ower dr iving range. Do not ride
the br akes or ho ld t he pedal down too
long o r too often. This could cause the
brakes to get hot and diminish braking
efficiency .
- Do not " ride the brakes" by rest ing you r
foot on the pedal when you do not intend
to brake. This may ca use the brakes to
overheat, premature wear and increased
stopping distance .
- Under certain cl imatic and ope rat ing
conditions such as passing thro ugh wa
ter , dr iv ing in heavy rain o r after washing
the vehicle , the effectiveness of the
brakes can be reduced . In winte r, ice can
accumu late on the bra ke pads, lin ings,
d iscs a nd drum s. Carefu lly app ly bra ke s
for a test. Brakes w ill dry and ice co at
ings w ill be cleaned
off after a few care
fu l brake applicat ions.
- Driving for an exten ded period o f time o n
salt -cove red roads without using your
brakes can a lso affect braking efficiency .
C lean
off accum ulated salt coating from
brake discs and pads with a few careful
brake applications.
- I f you damage the front spoiler, o r if you
install a different spoiler, be sure the air
f low to the front brakes is not obstruct
ed. Otherw ise the brak e system could
overheat reducing the effectiveness of
the entire brake system.
- Failure of one b rake circuit will impai r
the braking capab ility result ing in an in
creased s topping distance. Avoid driving
the vehicle a nd have it towed to the ne ar
est a uthorized Audi dea le r or qu alified
wo rkshop.

Replacing wh eels/ tire s
Vehicles w ith all-wheel drive must a lways
have tires of the same size. Also avoid tires
with different tread depths. For details see
page ¢
page 284, New tires and replacing
tires and wheels .
.&_ WARNING
Always adjust your driving to road and traf
fic conditions . Do not let the extra safety
afforded by all-wheel dr ive tempt you into
tak ing extra risks.
-Although the all-wheel dr ive is very ef
fective, always remember that braking
capacity is limited by t ire traction . You
sho uld therefore not dr ive at excessive
speeds on icy or s lippery road surfaces.
- On wet road su rfaces, be careful not to
dr ive too fast because t he front wheels
cou ld beg in to s lide on top of the wa ter
(aquaplaning). If this sho uld occ ur, you
w ill have no warning from a sudden in
crease in engine speed as with a front
whee l drive vehicle. A lways drive at
speeds wh ich are suited to the road con
ditions -risk of c rash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting
the engine.
I f a vehicle w it h a conventional energy system
i s not driven for a long pe riod of time, the bat
tery is disch arged by idling c urrent cons umers
(e .g. immobilizer) . In ce rtain c ircumstances it
can result in there being insufficient energy
ava ilab le to start the engine .
I n tell igen t energy management in your vehi
cle hand les the d istribution of electrical ener
gy . Starting abi lity is marked ly imp roved and
the life of the battery is extended.
Int ellig ent technolog y 229
Basica lly, energy management consis ts of
batte ry diagnosi s, idling cur rent manage
ment
and dynamic energy management.
Battery diagnosis
B attery diagnosis continuously de termines
the state of the battery . Sensors determine
batte ry voltage, battery current and battery
temperature . This determines the current
state of charge and the power of the battery.
Idling current management
Id lin g cur ren t man agement reduces energy
consumption while the vehi cle is standing.
With the ig nition switched off, it controls the
energy supply to the various electrical compo nents. Data from battery diagnos is is cons id
ered.
Depend ing on the battery's state of cha rge,
individual cons umers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability.
Dynamic energy manag ement
While the vehicle is being driven, dynamic en
ergy management distrib utes the energy ge n
erated according to the needs of the individ u
al components. It regulates consumption, so
that more electrical energy is not being used
than is be ing generated and ensures an opti
mal state of charge for the battery .
(D Tips
-But even e nergy management cannot
negate the limits of physics. Consider
t hat the powe r and l ife of a bat tery are
l imited.
- If start ing ability is threatened, you are
informed by a warning ¢
page 230,
Driver notification in the instrument
cluster display.

230 Intellig ent technol ogy
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time
of year. Abundant electr ical energy is re
qu ired, but only a little is generated. It is also
cr itical if the e ngine is not running and elect ri
cal components a re turned on. In th is in
stance energy is being consumed but none is being generated .
I t is in precisely these situations that you w ill
notice energy management actively regulat
ing the distrib ution of energy.
Vehicle stand s for an ext ende d period
If you do not drive your vehicle over a period
of several days or weeks, electrical compo
nents are gradually cut back o r switched off .
This reduces energy cons umption and main
tains starting capab ility
over a longer period.
Take into consideration that when you un lock
your ve hicle, some convenience functions,
such as the interior ligh ts or the power seat
ad justmen t, may not be available. The con
venience functions will be available again
when you turn on the ignition and start the
engine.
With the engine turned off
I f you listen to the radio, for example, with
the eng ine turned off or use other MM I func
tions, the battery is being discharged .
I f sta rting capability is jeopa rdized due to en
e rgy consumpt ion, the follow ing warning ap
pears in the MMI disp lay:
Ple ase s tart engin e, otherwi se system will
s wit ch off in 3 minute s.
The warning ind icates that the system will be
turned off automatically after 3 m inutes .
If
you wish to cont inue us ing the functions, you
have to start the engine.
With the eng in e runnin g
Although e lectrical energy is gene rated when
the vehicle is being driven, the battery can be
come discharged. This happens mostly when
little energy is being generated and a great
deal consumed and the battery's state of
charge is not optimal.
To bring the energy balance back into equili brium, consumers which req uire especially
large amounts of energy are temporar ily cut
back or sw itched off. Heat ing systems in par
t icular require a great deal of energy. If you
notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been tempora rily cut back or switched
off . These systems w ill be available again as
soon as t he energy balance has been restored.
You w ill also notice that engine id le speed has
been increased slightly . T h is is normal and not
a cause for con cern. By inc reas ing engine id le
speed the additional energy required is gener
ated and the battery is charged.
Driver notification in the instrument
cluster display
If battery power drops into the range where it
can limit the ability of the engine to start, this
is shown in the instrument cluster display
with the fo llow ing driver message:
(•) low batte ry charge: bat tery w ill be
ch arg ed whil e dri ving
This notificat ion reminds you that the starting
capability of the engine may be lim ited. As
soon as you start dr iv ing again, the battery
will be recharged and the not ificat io n will go
out .
Driver notific ation app ear s a nd goe s out
again
If this driver notification appears after the ig
nition is turned on or wh ile driving and it goes
out again after a while, the battery has been
adequately recharged. .,.
232 Driving and environment
Driving and
environment
The first 1,000 miles
(1,500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the fir st 600 miles (1,000
kilometers ):
.,. Do not use full throttle.
... Do not d rive 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 kilomete rs):
.,. Speeds can gradually be increased to the
max imum pe rm iss ible road or eng ine speed .
During and after break-in per iod
... Do not rev the eng ine up to high speeds
when it is cold. Th is app lies whether the
transmission is in N (Neutra l) or in gear.
After the brea k-in period
... Do not exceed max imum engine speed un
der any circumstances.
... Upshift into the next higher gear before
reaching the red area at the end of the tach
ometer scale¢ page 10.
During the first few hours of driving, the en
g ine's inter na l friction is higher than later
when all the moving parts have been broken
i n. How well this break- in process is done de
pends to a conside rable extent on the way the
ve hicle is driven du ring the first 1,000 miles
(1, 500 kilome ters).
(D Note
E xtremely high engi ne speeds are auto
mat ica lly r educed. However, these rpm
lim its are programmed for a n engine well
r u n- in, not a new eng ine.
{® For the sake of the environment
Do not drive with unnecessarily high en
g ine speeds - upshifting ear ly saves fuel,
reduces no ise and protects the environ
ment.
, New tires
If your vehicle is runni ng on new tires, drive
part icularly caref ul for the first 350 miles
(500 kilomete rs) afte r fitt ing.
A WARNING
N ew tires tend to be sl ippery and mus t al
so be "b roken -in" . Be s ure to remember
this dur ing the fi rst 350 mi les (500 kilo
meters) . Brake gently . Avoid fo llow ing
closely behind other vehicles or other sit
uations that m ight require sudden, hard
braking.
New brake pads
Remember that new brake pads do not have a
full bra king effect dur ing the fi rst 250 m iles
(400 kilomete rs) afte r they a re insta lled.
New brake pads have to be "burnished in" be
fo re t hey have optima l grab¢
A .
During the break- in period, you should avoid
putting severe loads on the brakes. Severe
l oads include, for example, sudden hard brak
i ng, in particular at very high speeds or, for
example, on mounta in passes .
A WARNING
New b rake pa ds don't have t he bes t stop
pi ng power and mus t be "broke n-in " dur
i ng the in iti al 1 00 to 150 mi les (150 to
20 0 kilometers) of no rma l city driving . You
can compensate for this by pressing the
br ake peda l mo re f irm ly . This also applies
l ater when new pads are installed.
Catalytic converter
Applies to vehicles: with gasoline engine
It is very important that your emission con
trol system (catalytic converter) is function
ing properly to ensure that your vehicle is run
ning in an environmentally sound manner .
... Always use lead-free gasoline c::> page 249,
Gasoline .
... Never run the tank down all the way to emp
ty .
... Never put too much motor oil in your engine
c::> page 263, Adding engine oil 't=r..
.,. Never try to push-or tow-start your veh icle.
The catalytic converter is an eff icient "clean
up" device built into the exhaust system of
the vehicle. The catalytic converter burns
many of the pollutants in the exhaust gas be
fore they are released into the atmosphere.
The exclus ive use of unleaded fuel is cr it ically
i mportant for the life of the cata lytic convert
e r and proper functioning of the engine.
& WARNING ,~
T he 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 operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can
cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
manifold, exhaust p ipes, catalytic con
verter or heat shields . During driving, the
substance used for undercoating cou ld
overheat and cause a fire.
(D Note
- Be aware that just one tank f illing with
leaded fuel will already seriously de-
grade the performance of the catalytic
conve rter.
Dri vin g and en vironm ent 233
-Do not exceed the correct engine oil level
c::> page 263.
- Do not drive until the fue l tank becomes
completely empty. The engine cou ld mis
fire. Unburned fuel could also get into
the exhaust system and this cou ld cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve
hicle is mov ing.
- Do not continue to operate your veh icle
under these conditions, as otherwise fuel
can reach the catalyt ic converter. Th is
cou ld result in overheating of the con
verter, requir ing its replacement.
- To assure efficient operation of the Emis
sion Control System:
- Have you r vehicle main tained properly
and in accordance w ith the se rv ice rec
ommendations in your Warranty & Maintenance book let.
- Lack of proper maintenance as we ll as
improper use of t he vehicle will impair
the function of the emission contro l
system and could lead to damage.
@) For the sa ke of the env ironment
Even when the Emission Control System is
operating properly, the exhaust gas can have a sulfur-like exhaust gas smell under
some operat ing states. This depends on
the sulfur content of the fuel being used .
Using a different brand of fuel may help,
or filling the tank with lead-free s uper
g rade gasoline.
Diesel particulate filter
App lies to vehicles: wit h diese l eng ine
The diesel part iculate filter filters nearly all of
the soot pa rticles out of the exhaust . T he fil
te r clea ns itself automat ica lly under no rma l
driv ing cond itions. If the filter cannot clean it
self (for example, because you are on ly driving
short distances), the fi lter becomes clogged
with soot and the
