the engine will start.
By pressing the [STAR T ENGINE STOP] button without depressing
the clutch or the brake peal, the ignition is switched on and switched
off by pressing it again.
If the engine does not start immediately, stop trying after 10 seconds
and then try to restart the engine about 30 seconds later.
After a cold engine is started, there may be a brief period of increased
noise because oil pressure must first build up in the hydraulic valve
adjusters. This is normal and not a cause for concern.
Driver message in the instrument cluster display
No key identified
This message appears when the !START ENGINE STOP] button is
pressed if there is no master key inside the vehicle or if the system
does not recognize it. For example, the master key cannot be recog­
nized if it is covered by an object (e.g. aluminum brief case) which
screens the radio signal. Electronic devices such as cell phones can
also interfere with the radio signal.
Press brake pedal to start engine
This message appears if you press the !START ENGINE STOP)
button to start the engine and do not depress the brake pedal. The
engine can only be started if the brake pedal is depressed.
Engage N or P to start engine
This message appears when attempting to start the engine if the
selector lever for the automatic transmission is not in the P or N posi­
tion. The engine can only be started with the selector in these posi­
tions.
Key not in vehicle
This message appears along with the.:! symbol if the master key is
removed from the vehicle with the engine running. It is intended to
remind you (e.g. when changing drivers) not to continue the journey
without the master key.
If the master key is no longer in the vehicle, you cannot switch on the
ignition after stopping the engine and you also cannot start the
engine again. Moreover, you cannot lock the vehicle from the outside
with the key.
Shift to P, otherwise vehicle can roll away. Doors do not lock if lever
is not in P.
This message appears for safety reasons along with a warning signal.
It appears if the selector lever for the automatic transmission is not
in the P position when switching off the ignition with the
!START ENGINE STOP] button. Move the selector lever to the P _..

Corrosion
T he re may be a te ndency fo r d irt to build u p on the bra ke pads and
co rrosion to form on the d iscs if the car is not dr iven reg ularly o r only
for short trips with litt le use of the bra kes .
If the brakes a re not used freq uen tly, or if co rrosion has formed o n
the discs, it is advisable to clean off the pads and discs by braking
fir mly a few times from a mode rat ely h igh spee d~ & .
Faults in the brake system
If yo u sh ou ld noti ce a sudden increase in b rake peda l trave l, then one
of the two brake circu its may have failed~& .
Low brake fluid level
Ma lfunctions can occ ur in t he brake system if the brake fluid level is
t oo low. The bra ke f lu id level is moni tore d elec tron ically.
Brake lin ing wear status
Brake lin ing wear may be checked by v isua l inspect ion of the condi­

& WARNING
• You should perform braking maneuvers for the purpose of
cleaning the brake system only if road conditions permit. Other
road users must not be put at risk - you may cau se an accident!
• Before descending a steep grade, reduce speed and shift trans­
mission into a lower gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or too often . This could
cause the brakes to get hot and diminish braking efficiency.
• Do not "ride the brakes " by resting your foot on the pedal when
you do not intend to brake . This may cause the brakes to overheat ,
premature wear and increased stopping distance.
• Under certain climatic and operating condition s such as
passing through water , driving in heavy rain or after washing the
& WARNING (co ntinued )
vehicle, the effectiveness of the brakes can be reduced . In winter,
ice can ac cumulate on the brake pads, linings, dis cs and drums.
Carefully apply brakes for a test. Brakes will dry and ice coatings
will be cleaned off after a few careful brake appli cations.
• Driving for an extended period of time on salt-covered roads
without u sing your brakes can also affect braking efficiency . Clean
off accumulated salt coating from b rake discs and pads with a few
careful brake applic ations.
• If you damage the front spoiler, or if you install a different
spoiler, be sure the air flow to the front brakes i s not obstructed .
Otherwise the brake system could overheat reducing the effective­
ness of the entire brake system.
• Failure of one brake circuit will impair the braking capability
resulting in an increased stopping di stance. Avoid driving the
vehicle and have it towed to the nearest authorized Audi dealer or
qualified workshop.

& WARNING
• Never let the vehicle roll to a stop with the engine shut off.
• If the brake booster is not working, for example when towing
your vehicle , or because the brake booster has somehow been
damaged, the brake pedal mu st be pressed considerably harder to
make up for the lack of booster assistance. •

0 Note
• Never use a power washer to clean the power top itself.
• To avoid damaging your vehicle, always make sure that there is
suff icient distance between the spray head and soft mater ials l ike
rubber hoses, plastic parts and sound -deadening materials. Never
aim the spray head at the same po int for a long time. This also applies
to cleaning headlights and painted bumpers. Remember: the closer
the nozzle is to the surface of the mater ial, the greater the stress on
the material. •
Power top care
The power top requires special care.
Keeping your top looking great and mak ing certain that it lasts a long
time depend to a great extent on proper use and care. Remove bird
droppings as soon as possible, since the corrosive chemicals in them
wi ll cause the rubber impregnation in your top to swell and possibly
allow the fabric to leak.
With
normal soiling, all you need to do is clear the top with a soft
brush and clear water. 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 br ush
using a convert ible top cleaner . Always brush in the direction of the
fabric from front to rear. Rinse with plenty of clear water, and allow
the top to air -dry .
Chamois are not sui tab le for drying the top .
Never use gasoline, spot remover, benzene, paint thinner or solvents
to remove spots. We recommend that you only use cleaners espe­
cially formulated for use on convertib le tops, and that you follow the
produce use directions carefully . Authorized Audi deals can provide
detailed information.
