G). When it starts to rain, the rain sensor will automatically activate
the intermittent wiping mode .
To reduce the sensitivity of the sensor ,
move switch @down . To
increase the sensitivity, move the switch up. The highe r you adjust
the sensitivity, the faster the sensor wi ll react when it senses mois ­
ture on the windshield. The pauses between wiper turns depend not
only on the sensitivity setting, but on the vehicle speed as well.
During brief stops, e.g. at a red light, wiper motion will automati ­
cal ly be reduced to the next lower speed. Wipers already turning at
low speed. change to intermittent wiping.
When the ignition is turned on, the washer jets a re heated .
With the low beam headlights switched on, pull the wiper
lever
towards you only briefly to clean the windshield. Ho lding the wiper
lever would also engage the headlight washer system each time you
clean the windshield and would drain the washer fluid reservoir
prematurely. ..

Au tomatic dimming fun ction
The automatic dimming function is activated every time the ignition
is turned on. The green indicator lig ht is lit to ind ica te auto dimming
is active.
When dimming is activated, the inside mirror will darken
automati ­
cally
in response to the amount of light striking the mirror (such as
headlights from rearward approaching vehicles). Even in d imm ing
mode , the mirror surface turns bright when :
• the interior light is switched on
• reverse gear is engaged .

& WARNING
The glass of the inside rearview mirror is layered and contains an
electrolyte to achieve its properties. Be aware of liquid electrolyte
leaking from a broken mirror glass. This liquid can cause irritation
to skin, eyes, and respiratory system. If you get electrolyte in your
eyes or on your skin, immediately rinse with plenty of water. If irri­
tation persists, seek medical attention.
0 Note
Liquid electrolyte leaked from a broken mirror glass will damage any
plastic surfaces it comes in contact with. Clean up spilled electrolyte
immediately with clear water and a sponge.
[ i] Tips
• If you switch off the automatic dimming function on the inside
mirror, automatic dimming of the outside mirrors will likewise be
disabled.
• Check to make sure there are no objects preventing light from
reaching the inside mirror.
• Do not attach any stickers to the windshield in front of the light
sensor, as this would interfere with the automatic operation of the
headlights and the automatic dimming of the inside mirror.•

0 Note
• Curved (i.e. convex) mirror surfaces increase your field of view.
Remember that vehicles or other objects will appear smaller and
farther away than when seen in a flat mirror . If you use this mirror to
estimate distances of following vehicles when changing lanes, you
could estimate incorrectly and cause an accident.
• If the mirror housing is moved unintentionally (for example,
while parking your vehicle), then you must first fold the mirror elec­
trically. Do not readjust the mirror housing manually. You could
damage the motor which controls the mirror.
[ i] Tips
I f there should be a malfunction in the electrical system, you can
still adjust the outside mirrors by pressing the edge of the mirror. •
Applie s to vehic les : w ith au tomat ica lly dim ming ou ts id e m irrors
Automatic dimming for the outside mirrors *
The outside mirrors dim at the same time as the inside mirror. When
th e ignition is switched on, the mirrors automatically dim
depending on the amount of flight striking the mirrors (such as
headlights shining into the vehicle from the rear). When you switch on the interior light, or when you move the
selector lever into
R (Reverse), the dimming function stops and the
mirrors return to their original condition (not darkened).
[ i] Tips
The automatic dimming feature on the mirrors will not operate
properly if the light shining on the mirrors is blocked by other
objects .•

-Cleaning and protection P':ft':I _______________ _
& WARNING
• Do not clean the underside of the chassis, fenders, wheel
covers, or other hard to reach parts without protecting your hands
and arms. You may cut yourself on sharp-edged metal parts.
• Always read and heed all WARNINGS and other information
~ page 230.
0 Note
• Never try to remove dirt, mud or dust if the surface of the vehicle
is dry. Never use a dry cloth or sponge, since this could scratch your
vehicle's paint or windows.
• Never wash your car in bright sunlight. Drops of water act as
magnifying lenses and may damage your paint .
• When you wash your car in the winter: if you rinse your vehicle
with a hose, be careful not to aim the stream of water directly at
locks, or at door or hatch openings - they can freeze shut.
• Never use sponges designed to remove insects, or any kitchen
scouring sponges or similar products. They can damage your paint
finish .
• Never use a dry cloth or sponge to clean the headlights. Only use
wet cloths or sponges to prevent scratches . It is best to use soapy
water.
<£> For the sake of the environment
In the interest of the environment, the vehicle should only be
washed in special wash bays. •
Washing your vehicle with a power washer
Cleaning the exterior of your car with a high-pressure
power washer is safe as long as you observe a few simple
rules.
- Before using the power washer, make sure you have read
and understood the WARNINGS~
& in "General infor­
mation" on
page 230.
Always follow the operating instructions for the power
washer.
Make sure that the jet on the spray hose produces a "fan
shaped spray".
Do
not hold the spray nozzle too close to soft materials.
When cleaning the vehicle with a power washer always follow the
operating instructions. This applies particularly to the
operating
pressure and the spraying distance. Maintain a sufficient distance
to soft materials such as rubber hoses and sound/vibration dead­ ening materials {particularly on the underside of the engine hood).
Do not use a jet which sprays water in a
direct stream or one that
has a
rotating jet.
Water temperature should not exceed 140
°F (60 °C).
& WARNING
Never wash tires with a jet that sprays water in a direct stream.
This could cause invisible damage to the tires and weaken them,
even if the spray is from a relatively long distance and for a short
time . Damaged and weakened tires can fail and cause accidents
and personal injury.
0 Note
• Never use a power washer to clean the power top itself.

Cleaning and protection -
----------------
•
• To avoid damaging your vehicle, always make sure that there is
enough d istance between the sprayer and sof t materials like rubber
hoses, plastic parts and sound -deadening materials . Never aim the
sprayer at the same point for a re latively long period of t ime. This
also applies to cleaning headlights and painted bumpers. Remember : the closer the nozzle is to the surface of the material,
the greater the stress on the material. •
Power top care
The power to p requires s pecial c are.
Keeping your top look ing great and making certain that it lasts a
long time depend to a great extent on proper use and care. Remove
bird droppings as soon as possib le, 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 c lear 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 brush
using a convert ib le top cleaner . Always brush in the direction of the
fabric from front to rear . R inse with plenty of clear water, and allow
t he t op to air-dry .
Chamois are not suitab le for drying the top.
Never use gasoline, spot remover, benzene, paint thinner or
solve nts to remove spots . We recommend that you only use
cleaners especia lly formulated for use on convertib le tops , and that
you fol low the produce use d irections carefully. Authorized Audi
dea ls can provide detailed information.
& WARNING
Always read and h eed all WARNINGS and the information
=> page 2 30 .
0 Note
Never use a high -pressure power was her to clean the power top. •
Wind deflector
Clear the wind deflector with water or, if it is heavily soi led, a chem ­
ica lly neutra l cleaning solution .
& WARNING
Always read and heed all WARNINGS and the information
=> page 2 30 . •
Waxing

- U se a manua lly ap plied ca r wa x occasi onall y to p ro tect
t h e paint.
A good wax coat ing protects the vehicle paint to a large extent
against the environmental factors listed under=> page 230,
"Washing" and even against slight scratches .
You can use a liquid car wax to protect your paint as soon as one
week after your vehic le has been delivered.
Even if you regular ly use a
waxing process in automa tic car was hes,
we recommend that you manual ly apply a coat of wax to give the
paint ex tra p rotecti on, particular ly if wa ter n o longer beads on the
