& WARNING
Automatic headlights are only intended to assist the driver. They
do not relieve the driver of his responsibility to check the head­
lights and to turn them on manually according to th e current light
and visibility conditions . For example, fog cannot be detected by
the light sensors. So always switch on the headlights under these
weather conditions and when driving in the dark
io.
[ i ) Tips
• The light sensor for headlight cont rol is located in the rear view
m irror mo unt. You s hou ld therefore not apply a ny st ic kers to the
windshield in th is area in order to prevent malfunct ions or fa ilures.

(I] Tips
The illumination for the instrument cluster lights up whenever you
switch on the ignition with the vehicle headlights off . As the daylight
fades, the instrument cluster illumination likewise dims automati­
cally and will go out completely when the outside light is very low.
This feature is meant to remind you to switch on the headlights when
outside light conditions become poor. •
Appli es to veh icles : wi th xenon headlights
Xenon headlights
After starting the engine , the xenon headlights are automatically
adjusted to the load and angle of the vehicle (for example, during
acceleration and braking). This prevents oncoming traffic from expe­
riencing unnecessary headlight glare from your xenon headlights .
If the system is not operating properly, a warning symbol in the Auto­
Check Control is displayed~

Ap plies to vehi cles: with adap tive light
Adaptive light
When driving around bends, the relevant area of the road
is better illuminated.
Fig. 69 Adaptive light
when driving
The benefit of adaptive light is that the curve and the edge of the road
are better illuminated ~ fig. 69. Dynamic adaptive light is controlled
automat ically, depending on vehicle speed and steering wheel angle.
When driving around bends, the headlights are controlled according
to steering wheel angle . So that there is no black hole ahead of the
vehicle , the two main beams pivot at different angles. .,.

• 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.

Have the battery checked when you take your vehicle in for service .
You are well advised to replace a battery that is older than 5 years.
With certain types of a irbag deployment, the battery is disconnected
from the vehicle electrica l system for safety reasons~
& in "Repair,
care and disposal of the airbags" on
page 213.
Disconnecting the battery terminals
Some vehicle funct ions (power window regulators, for example) are
lost if the battery terminals are disconnected. These functions have
to be relearned after the battery termina ls are connected aga in . To
prevent this, the battery should only be disconnected from the
vehicle electr ica l system when absolute ly necessary for repairs.
Vehicles not driven for long periods
If you do not drive your veh icle over a period of several days or weeks,
electrical components are gradually cut back or switched off. This
reduces energy consumption and maintains starting capability ove r a
longer period
~ page 247.
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the master key remote function or
powe r seat adjustment, may not be available. The convenience func ­
tions will be available again when you turn on the ignition and start
the engine.
Winter operation
During the winter months, battery capacity tends to decrease as
temperatures drop. This is because more power is also consumed
while starting, and the headlights, rear window defogger, etc., are
used more often .
Avoid unnecessary power consumption, particu larly in city traffic or
when travel ing only short distances. Let your authorized Audi dealer
check the capacity of the vehicle battery before winter sets in
~ page 293. A well charged battery will not only p revent start ing
problems when the weather is cold, but will also last longer.
Safety first
(I] Tips
If your vehicle is left standing for several weeks at extremely low
temperatures, the vehicle battery shou ld be removed and stored
where it will not freeze. This will prevent it from being damaged and
having to be replaced. •
Working on the battery
Be especially careful when working on or near the
battery.
The battery is located in the luggage compartment under the
floor. Before you check anything in the lu~gage compart­
ment,
read and heed all WARNINGS =:,& .
Always heed the safety warnings, when working on the vehicle
battery or the vehicle electrical system to prevent injury .
The following WARNINGS are very important when
working on the battery:
Always heed the following WARNING SYMBOLS and safety pre ­
cautions when working on the battery.
Always wear eye protection.
