Braking
New brake pads
New b rake pads do not achieve the ir full braking
effect during the first 250 miles (400 km) . They
must be "broken in" first . However, you can com­
pensate for the slightly reduced brak ing force by
pressing firmly on the brake pedal. Avoid heavy
braking dur ing the break-in per iod.
W ear
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 c ity and on curves or with a sporty driving
style .
Operating noise
Noises may occur when braking depending on the
speed, b raking force and outside conditions such
as tempe rature and humidity.
W et conditions or road salt
In certain s ituations, for example after dr iving
through water, in heavy rain or after washing
your car, the brak ing effect may be reduced due
to mo isture or ice on the brake rotors and brake
pads. The brakes must be "dr ied" first wit h 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. Th is action,
which is not felt by the driver, happens at regular
i n tervals a nd ensu res a better reaction time for
the bra kes in wet weather .
The braking effect can also be reduced if you are
driving on salted roads and you do not apply the
brakes fo r long periods of time . The laye r of salt
on the brake rotors and pads must be wo rn off
fi rst when the b rakes are app lied.
Corrosion
Leaving the vehicle parked for long periods of
time, low mi leage and avo iding heavy brak ing
136
can con trib ute to corros ion on t he b rake roto rs
and to dirty brake pads .
I f you usu all y avoid he avy br aking or if there is
corrosion present, occasiona l heavy brak ing at
high speeds is recommended to clean the brake
rotors and pads~.&. .
Brake system malfunction
if you not ice that the b rake peda l t ravel has sud­
denly gotten larger, t hen a b rake c ircuit in the
dual-c ircuit brake system may have failed. Drive
to an authorized Audi dea ler o r authorized Audi
Se rvice Facility immediate ly to have the prob lem
corrected . On the way there, dr ive with reduced
speed and keep in mind tha t you w ill need a lon­
ger distance to stop and you will need to press
the brake pedal harder.
l o w brake fluid level
When the brake fluid level is low, malfunctions in
the brake system may occur. The brake fluid level
i s electronically monitored.
Brake booster
The bra ke boos ter amp lifies the p ressure yo u ap ­
ply to the brake pedal. It only wor ks when the en­
gine is running .
A WARNING
- Only app ly the bra kes for the purpose o f
cleaning the brake system w hen road and
traffic conditions permit. You must not en­
danger other road users. This i ncreases the
r is k of an accident.
-
- Never let the ve hicle roll while the engine is
s to pped because t his i ncreases the ris k of an
acciden t.
Q) Note
- Never let the brakes "rub" by pressing the
peda l lightly when braking is not actually
necessary . This causes t he b rakes to over ­
heat and incr eases brak ing distanc e and
c a u ses we ar.
- Before driving a long d istance o n a steep

If you need to brake additionally,
brake in interva ls and not continuously .
(D Tips
-If the brake booste r is no t working, you
must p ress the brake pedal with much more
fo rce than norma l.
- If you retrofit you r vehicle with a front spoil­
er, whee l covers or s imilar items, make sure
that the air flow to the front whee ls is not

Offroad vehicle?
Your Audi is not an offroad vehicle - the re is not

_& WARNING
-Also, in vehicles with all wheel drive, adapt
yo ur driving style to the current road and
t raffic conditions . Do not let the increased
sa fety provided tempt you into tak ing risks,
because th is increases the r isk of an acci­
dent.
- The brak ing ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not diffe rent from a two whee l dr ive vehi­
cle . Do not be tempted to accelerate to a
high spee d when t he road is slippe ry, be­
ca use this increases the risk of an accident.
- Note that on wet streets, the front wheels
can "hy droplane" if dr iving at speeds that
are too hig h. Unlike front whee l drive
vehicles, the eng ine does no t r ev highe r su d­
denly when the vehicle begins hydroplaning .
For this reason, pay attention to the road
condit ions regar dless of you r speed to re­
duce the r isk o f an accident.
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a ve hicle w ith a co nventional e nergy sys ­
tem is not driven for a long time, the battery is
138
dra ined by equipment (for examp le, the immobi l­
izer) . In certain circ umstances, there could may
not be enough ene rgy to sta rt the eng ine.
Yo ur vehicle is equipped wi th an inte lligen t ener ­
gy management system for dist ributing elec trici ­
ty. This significant ly improves the starting ability
and increases the batte ry life.
The ene rgy management sys tem Is m ade up of
batte ry diagnosis , standby current manage­
ment
and dynamic ene rgy management .
Battery diagnosis
The ba ttery diagnos is determines the batte ry
c ha rge level. The sensor s de ter mine the batte ry
vo ltage, the batte ry cu rrent, and the batte ry
tempera ture. The current cha rge level and the
perfo rmance of the battery a re determined base d
on this .
Idling current management
The idling cur rent m an age ment decreases the
energy used while parked . With the engine
switched off, it manages the energy distrib ution
to the different e lectr ica l components. Data from
the battery d iagnosis is taken into account for
th is.
Depend ing on the battery charge leve l, electrical
equipment is switched off one item after the oth ­
er, to prevent the battery from drain ing and to
maintain the sta rting ability.
Dynamic energy management
W hile driv ing, dynam ic energy man agement dis ­
tributes the appropr iate amo unt of energy to the
electrica l eq uipment. It contro ls t he battery
charge level so that mo re energy is not used then
i s be ing generated in order to maintain an opti­
mal battery c harge level.
(D Tips
- Energy management cannot overcome the
laws of physics. Note that the charge level
and length of the battery life are limited.
- When the sta rting ability is endangered, the

What you should know
Maintaining the starting ability is the highest
priority.
A lot of stress is placed on the battery when driv­
ing short distances, in traffic, and at cold times
of the year . A lot of energy is used but little is
generated. It is also critical when the engine is not runn ing but elect rical equipment is switched
on. I n this case, ene rgy is used but none is gener­
ated.
In s ituations l ike this, energy management will
actively regu late the distribution of ene rgy.
Long pe riods without use
If you do not drive your vehicle for several days or
weeks, e lectrical equipment is gradually scaled
back or switched off . This reduces energy use and
ensu res the veh icle w ill be able to start afte r long
pe riods of time. Some convenie nce functions,
such a s in te rior lighting or powe r seat adjust­
men t, may not be available under certa in c ircu m­
stances . These convenience functions will be
ava ilable again once you switch the ign ition on
and start the engine .
With the engine switched off
The ba tte ry will d rai n if you use Infota inment
functions s uch as listen ing to the rad io whi le the
engine is switched off .
I f t he vehi cle's ability to start may be impaired by
the energy use, a mess age will appear in the In­
fotainment system disp lay . The message indi ­
cates that the system will sw itch off automatica l­
l y soon . If you would like to continue using the
f u nctions, yo u m ust start the eng ine.
With the engine running
A lthough elec trical energy is gene ra ted wh ile
d riving, the ba ttery can drain . This can happen
when little energy is generated, and m uch is used
and the charge leve l of the battery is not optima l.
To restore the ba lance o f energy, components
that requ ire large amo unts of energy a re tempo­
rari ly sca led back or switched off. Heating sys­
tems in particu lar require a great deal of energy .
If you notice, for example, that the seat heating *
Intelligent Technology
or rear window defogger is not work ing, t hen it
has been temporarily limited o r switched off.
These systems are availab le aga in as soon as the
energy supply has been restored .
In add ition, yo u may notice tha t the idle speed
has slig htly increased. That is normal and no
ca use for concern . Due to the increased id ling
speed, the additional required energy will be generated and the battery will be charged .
Notice about data

Check ing and F illing
Checking and Filling
Gasoline
Fuel supply
Applies to: vehicles with gaso line engine
Using the right fuel helps keep the environment
clean and prevents engine damage.
F u el r eco mmend ati on
The fuel recommended for your vehicle is unle ad­
e d pr em ium
grade gasoline . Audi recommends
using TOP TIER Detergent Gasoline with a mini­
mum octane rating of 91 AKI (95 RON). For more
information on TOP TIER Detergent Gasoline,
p lease go to the offic ial website
(www.toptiergas .com).
The recommended gasoline octane rating for
your engine can also be found on a label located on the ins ide of the fuel filler flap . This rating
may be specified as AK I or RON .
Your veh icle may also be operated using unlead­
ed regular gasoline with a minimum octane rat ­
ing of 87 AKl/91 RON. However, using 87 AKI/91
RON octane fuel w il l slightly reduce engine pe r­
forma nce.
Us e un leade d gaso lin e onl y. Unleaded gasoline
is availab le throughout the USA , Canada, and in
most European countries . We recommend that
you do not ta ke your vehicle to areas or co unt ries
where un leaded gaso line may not be availab le.
For more information on refueling your vehicle,
see
¢ page 298 .
Octane rating
Octane rating indicates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignit ion and detonation . Therefore, buy ing
the correct grade of gasoline is very important to
he lp prevent poss ible engine damage and a loss
of eng ine performance.
Gasoline most commonly used in the Un ited
States and Canada has the following octane rat­
i n gs that ca n usually be found on the filler pump:
- Premium Grade: 91 - 96 AKI
296
- Regu la r Grade: 87 - 90 AK I
Explanation of the abbreviations:
AKI = Anti Knock Index = (R +M)/2 = (RON +MON)/
2
RON = Research Octane Number
MON = Motor Octane Number.
{[) Note
-Do not use a ny fue l w ith o ctane ratings low­
er than 87 AKI or 91 RON othe rw ise expen­
sive engine damage wi ll occur .
- Do
not use leaded gasoline. The use of lead­
ed gasoline will severely damage your vehi­
cle's catalyt ic converter and its ability to
control exhaust emissions .
Blended gasoline
Applies to: vehicles with gasoline engine
Use of gaso lin e conta ining alcoho l or MTBE
(meth yl tertia ry butyl ether )
You may use unleaded gasoline blended with al­
cohol or MTB E (commonly referred to as oxygen ­
ates) if the blended m ixture meets the follow ing
criteria:
Blend of g asoline methanol (wood alcohol o r
m eth yl alcoho l)
-Anti -knock index must be 87 AKI or h igher.
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more than 2% co -solvents.
Blend of ga soline and ethanol (grain alcohol or
ethyl alc ohol )
- Anti-knock index must be 87 AKI or h igher .
- Blend must not conta in more than 15% etha-
nol.
Blend of gas oline and M TBE
- Anti-knock index must be 87 AK I or h igher .
- Blend must contain not mo re than 1S% MTB E.
S easonall y adjusted gasoline
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iv ing . Dur-
i ng seasonal change-over, we suggest that you .,..

fill up at busy gas stations where the seasonal
adjustment is more likely to be made in time .
(D Note
-Methanol f uels which do not mee t these re­
quirements may ca use corrosion and dam­
age to plastic and rubber components in the
fuel system.
- Do not use fuels that fai l to meet the speci­
fied criteria in this chapter.
- If you are unable to determine whether or not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identif ied.
- Fuel system damage and performance prob­
lems resulting from the use of fue ls differ­
ent from those specified are not the respon­
s ibility of Audi and are not covered under
the New Veh icle or the Emiss ion Control
System Wa rrant ies.
- If you experience a loss of fue l economy or
driveability and performance problems due
to the use of one of these fuel b lends, we
recommend that you switch to unblended
fuel.
Gasoline additives
Applies to: vehicles with gasol ine engine
A majo r concern among many auto manufactur ­
ers is carbon deposit build-up caused by the type
of gasoline you use.
A lthough gasoline grades d iffer from one manu­
facturer to another, they have cer tain things in
common . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves . Al ­
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website (www.toptiergas .com) .
Check ing and Filling
After an extended period o f using inadeq uate
fuels, bui lt-up ca rbon deposits can rob your en­
gine of peak performance.
