as a pulsing motion of the brake pedal, ac
companied by some noises. In order for ABS
to be able to operate optimally in th is range,
you must keep the brake pedal depressed -
never "pump the brakes" . You should not ex
pect that braking d istances w ill be
shortened
under all circumstances with ABS . Braking dis
tance may even be slightly
longer, for exam
p le on gravel or wi th fresh snow on a slippery
surface .
If a sign ificant
speed differential between the
d rive wheels on one axle is determined (for
examp le, on a su rface that is s lippery
on one
side),
the EDS brakes the spinn ing whee l and
transfers power to the other drive whee ls.
This is done up to a speed of about 60 mph (100 km/h) . Noises from the brake system
signal that whee l spin is being controlled.
I f one whee l spins when starting from a com
p lete stop because o f a different grip (for ex
ample , one wheel o n ice), keep your foot
hard
on the accelerator until the veh icle starts to
move.
If the wheels spin , ASR wi ll automatically re
duce engine torque and match power to road
surface conditions .
Switching on Sport mod e
In specific driving situations (e.g. Launch Con

Switching ASR /ESP off
In certain sit uations (e .g . in deep snow, on a
l oose surface, o r when rocking the vehicle
free), switch ASR and ESP off by pressing the
[ill button for more than 3 seconds. The ind ica

Switching ASR /ESP on
Activate ASR/ ESP by p ressing the [!I button
again. The message

Brake overheating
So that the disc b rake on a b raked wheel does
not overheat, the EDS switches off automati
ca lly if there is un usua lly severe loa ding at
th is wheel. The vehicle is st ill drivable and has
the same properties as a vehicle wit hout EDS .
As soon as the brake has cooled down, EDS
swi tches on aga in automatically.
A WARNING
- Even ESP, ABS, EDS and ASR cannot over
come the laws of physics . You should
keep this in m ind in particular on an icy
or wet road. If the systems intervene,
you shou ld adjust your speed immediate
ly to road and traff ic conditions . Do not
be tempted by the increased safety pro
vided to take risks -you risk having an
accident.
- Please keep in mind that the r isk of an
accident is i ncreased by driving too fast,
pa rti cularly in corners and on icy or wet
ro ads, and by drivi ng too close to the ve
hicle ahead . Even ES P, ABS, E DS and ASR
cannot eliminate the increased risk of
having an accident.
-Apply the throttle ca re fully when accel
erating on a consistently s lippery sur
face, e.g. on ice and snow . The drive
wheels can spin in spite of the EDS and thereby affect vehicle stability -you risk
having an accident .
- Please note that when ASR or ESP/ASR is
deactivated, the drive wheels can spin on
icy and slippery roads and the veh icle can
break away -the re is a risk of skidd ing!

Braking
New brake pads
During the firs t 250 miles (4 00 km), new
b rake pads do not possess their f ull braking

with ceramic brakes *. Yo u can compensate f or
this slightly reduced b rak ing power by push

Dynamic energy management
While the veh icle is be ing driven , dynamic en
e rgy management distributes the energy gen
erated according to the needs of the individu
a l components . It regu lates consumption, so
that more electrical energy is not being used
than is being generated and ensures an opti mal state of charge for the battery .
(D Tips
- But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are li mited .
- If starting ab ility is threatened, you are
i nformed by a warn ing
<=> page 156,
Driver notification in the instrument
cluster display .
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. Abu ndant electr ical energy is re
qu ired, but only a little is generated . It is also
cr itical if the engine is not running and elect ri
cal components are turned on. In th is in
stance energy is being consumed but none is
being generated .
It is in precisely these situations that you w ill
notice energy management actively regulat
ing the distrib ution of energy .
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of severa l days or weeks, elect rical compo
nents are gradually cut back o r switched off .
This reduces energy consumption and main
tains starting capabi lity over a longer period.
Take into considerat ion that when you un lock
your vehi cle, some convenience functions,
such as the remote key or power seat adjust
ment, may not be available. The convenience
functions will be available again when you
turn on the ignition and start the engine. With the
engine turned off
If you listen to the radio, for examp le, w ith
the engine turned off, the battery is being dis
charged.
If starting capability is jeopardized due to en
ergy consumption , a message appea rs in the
driver information display.
You have to start the engine to charge the batte ry.
With the engine running
Although electrical energy is generated when
the vehicle is being driven, the battery can be
come discharged. This happens mostly when
little energy is being gene rated and a great
deal consumed and the battery's state of
charge is not optimal.
To bring the energy balance back into equili
brium , consume rs which requ ire espec ially
large amounts of energy are temporar ily cut
back or sw itched off. Heating systems in par
ticu lar 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 temporarily cut back or switched
off . These systems will be available again as
soon as the ene rgy balance has been restored.
You wi ll also notice that engine id le speed has
been increased slightly . Th is is normal and not
a cause for concern. By increasing engine idle
speed the additional energy required is gene r
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 following driver message:
(•i Low battery charge: battery will be
charged while driving
T h is not ificat io n r eminds you that the start ing
capability of the engine may be lim ited. As
soon as you start driving again, the battery .,..
-Have you r vehicle maintained properly
and in accordance with the service rec
ommendat ions in your Warranty
& Main
tenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impair
the function of the Emission Control Sys
tem and could lead to damage.
Sporty driving
Warming up and cooling down
By carefully warming up and cooling down
your vehicle, you can he lp ensure that it is not
overstressed unnecessarily during sporty driv
ing.
When warming up, the vehicle is driven at a maximum engine speed of
6000 RPM
(Vl0 engine) or 7000 RPM (V8 engine) in or
der to raise the engine oil temperature to a minimum of
140 °F (60 °(). The tires also on
ly reach their full road holding capability once
they have warmed up .
The cooling fan can continue to run in your ve h icle after the engine is switched
off. H owev
er, driving the vehicle to cool it down is part ic
ularly important. During sporty driving, the
engine and brakes, the exhaust system, and
the t ransm ission all become ex treme ly hot.
Before you park the vehicle, you shou ld d rive
it for a few mi les/kilometers at light load in
the low rpm range to allow it to coo l down .
Driving on a track
Before you take your vehicle out on a track,
ensure that it is in perfect condition. For ex
ample, you should check the tire tread and the brake pads . It is best to increase t ire pressure
by about 0 .3 bar .
When driving on a track, oil consumption may be somewhat higher than in "normal" opera
tion ¢page
180.
You shou ld definitely inspect your vehicle af
ter subjecting it to severe condit ions. Are the
brake pads OK? Is there anything unusual
Dri vin g and en vironm ent 159
about the ti res, including the inner and outer
sidewa lls (e.g . tread, blistering)? Are the air
intakes free of leaves and tire dust? Is the o il
l evel OK?
Your authorized Audi dea ler or qua lified work
shop will be happy to undertake an inspection
before and after use on the race track.
(D Tips
- Some race tracks (e.g . steeply banked
t u rns) may affect the response of the
ESP .
- When driven on a race track, all vehicle
parts are severe ly stressed. This can re
sult in increased wear.
Operation and maintenance
Fuel economy, env ironme nta l impact, and
wear on your eng ine, brakes and tires largely
depend on three factors:
- your personal driving style
- operating conditions
- technical limitations
By having your ve hicle reg ularly se rv iced by an
authorized Aud i dea ler helps to ens ure that i t
r uns properly and econom ica lly. The condition
of your veh icle not only affects its safety and
ability to ho ld its va lue, it a lso affects
f u el
con sumptio n.
The amount o f oi l used is re lated to engine
load and speed .
It is normal fo r the oil consump tion of a new
engine to reac h its lowest value after a certa in
mileage has been d riven.
You must drive your veh icle about 3,000 mi les
(5,000 kilometers) before you can p rope rly
assess oil consumpt ion.
This also app lies to fue l cons umption and en
gine output.
(D Note
- Have your veh icle ma inta ined properly
and in accordance with the service

Convertible top care
The convertible top requires special core.
Keeping your top looking great and making
certain that it lasts a long time depend to a
great extent on proper use and care. Remove b ird droppings as soon as possible, since the
corrosive chem icals in them will cause the
rubber impregnat io n i n your top to swell and
possibly allow the fab ric to leak.
W ith
normal soiling, all you need to do is
clear the top with a soft brush and clear wa
ter. Always brush in the direction of the fabric
from front to rear.
If the top is
very dirty and has spotted areas
clean it with a brush us ing a convert ible top
cl eane r. A lways brush in the direction of the
fabr ic from front to rear. Rinse w ith plenty of
clear wa te r, a nd a llow the top to air -dry.
Chamois are not suitable fo r d ry ing the top.
Never use gasoline, spot remover, benzene,
pa int thinner or solvents to remove spots. We
recommend that you only use cleaners espe
cially fo rmu lated for use on convertible tops,
a nd that you follow the p rod uce use directions

been left in a re latively natural condition. This
l eather offers particularly good comfort and
breathes well. F ine veins, closed grains, insect
b ites, skin folds, and subtle variations in color
remain visible. These characteristics demon
strate that the mater ial is natural.
Natural nappa leather is not covered by a col
or finish. It is therefore more sensitive to soil ing and wear, wh ich is something you need to
consider if children, animals or other factors
might prove to be particularly hard on the
leather.
By contrast, leather types that are covered by
a co lored finish layer are more durab le. This
has a posit ive effect on the leather's resist
ance to wear and soiling in daily use. On the
other hand, the typical cha racte rist ics of natu
r a l lea ther a re ba re ly or no t apparent. Howev
er, this does not mean that the leather itself
is of in ferior quality .
Care and handling
Because of the exclusive nature of the types of
leather that Audi uses and the ir unique prop
er ties (such as sensitivity to o ils, grease, so il
ing, etc.), you will need to be somewhat care
fu l with these leathers, and a certain type of
care is required . For examp le, dark clot hing
materials can discolor leather seats (especial
ly if such cloth ing is damp and was not dyed
correctly). Dust and d irt part icles in pores,
folds, and seams can have an abras ive effect
and can damage the leathe r su rface as well as
weaken seams.
The leather should be cleaned regularly as
needed . After having been used for a relatively
long t ime, your leather seats will acquire a
r ich aged finish. This is a characteristic of nat
ura l leather and a sign of true quality.
In order to ma intain the va lue of th is natural
p roduct ove r the life of your vehicle, you
should follow the recommendations below :
«I) Note
- To keep your leather from bleaching out,
do not allow it to be exposed to bright
Cleaning and protec tion 167
sunlight for long periods of time . If you
have to leave the vehicle parke d outside
for long per iods, cover the leather to
protect it from direct exposure to s un
light.
- Sharp objects on clothing, such as zip pers, rivets or sharp pieces on belts can
leave permanent scratches or scrape
marks on the surface of t he leather.
@ Tips
- After each time you clean the leather and
at regular intervals, use a leather preser
vative creme that contains UV-blockers
and that works into the leathe r. Th is
creme w ill nour is h and mo istu riz e the
lea ther, helping it to breathe and s tay
s u pple. It also helps to build up a protec
t ive coating on the sur face.
- Clean t he leather every 2 -3 mon ths,
and clean any areas that get soi led.
- Remove fresh marks made by ballpo int
pens, ink, lipstick, shoe pol ish, etc. as
soon as poss ible .
- P rese rve the color of the leather as need
ed by using a specia l co lore d lea the r ca re
creme to touch up areas of uneven color .
