Never dry windows with the same chamois
that you use to dry painted surfaces . Wax resi­
due on the chamois can impair vision through
the windows.
_& WARNING
- The windshield must not be treated with
water-repellent materials. They can in­
crease glare under poor visibility condi­
tions such as wetness, darkness, or when
the sun is low on the horizon. In addi­
tion, they can cause the windshield wip­
ers to chatter.
- Always read and heed all WARNINGS and
other information <=;>
page 162.
([) Note
-Never use warm or hot water to remove
snow and ice from windows and mirrors.
This could cause the glass to crack.
- To prevent damage to the wires of the
rear defogger, do not place any adhesive
stickers on the inside of the rear window
over the wires.
- To help prevent dirt from scratching the
window, always scrape in a forward di­
rection -pushing the scraper away from
you -never back and forth.
Weatherstrips
Complete car care includes the weatherstrips
as well.
.,. Apply a suitable rubber conditioner to the
weatherstrips from time to time.
To be able seal properly, the weatherstrips
around the hood, doors, rear lid, etc. must re­ main pliable . Spray the weatherstrips with sil­
icone or coat them with talcum powder or
glycerine to retain the flexibility of the rubber
and to protect them against freezing in the
winter .

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned
out bulbs for you .
It is becoming increasingly more and more
difficult to replace vehicle light bulbs since in
many cases, other parts of the car must first
be removed before you are able to get to the
bulb . This applies especially to the light bulbs
in the front of your car which you can only
reach through the engine compartment.
Sheet metal and bulb holders can have sharp
edges that can cause ser ious cuts, and parts
must be correctly taken apart and then prop­
e rly put back together to help prevent break­
age of parts and long term damage from wa­
ter that can enter housings that have not been
properly resealed.
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs
for you, since your dealer has the proper tools,
the correct bulbs and the expertise.
Gas discha rge lamps (Xenon lights}*:
Due to the high electrical voltage, have the
bulbs replaced by a qualified technician.
H eadlights with Xenon light can be identified
by the high voltage sticker.
A WARNING
Contact with high-voltage components of
the electrical system and improper re­
placement of gas discharge (Xenon) head­
light bulbs can cause serious personal in­
jury and death.
- Xenon bulbs are pressurized and can ex­
plode when being changed. -
Changing Xenon lamps requires the spe­
cial tra ining, instructions and equip­
ment.
- Only an authorized Audi dealer or other
qualified workshop should change the
bulbs in gas discharge lamps.
A WARNING
=
There are parts with sharp edges on the
openings and on the bulb holders that can
cause ser ious cuts.
- If you are uncertain about what to do,
have the work performed by an author­
ized Audi dealer or other qualified work­
shop. Serious personal injury may result
from improperly performed work.
@ Tips
- If you must replace the light bulbs your­
self, a lways remember that the engine
compartment of any vehicle is a hazard­
ous area to work in. A lways read and
heed all WARNINGS
c:::> page 172, Engine
compartment
c::> &. .
-It is best to ask your authorized Audi
dealer whenever yo u need to change a
bulb .

5. Connect the other end of the red jumper
cable to the positive terminal @of the
booster battery @.
6. Connect one end of the black jumper ca­
ble to the negat ive terminal @of the
booster battery @.
7. Connect the other end of the black jumper
cable to the negative terminal (bolt head)
@ in the external start ing point @ of
your vehicle.
8. Route the jumper cables so that they can­
not catch in any rotat ing parts in the en­
gine compartment.
Starting the engine
9. Start the engine of the vehicle providing
assistance and allow it to run at id le .
10. Now start the engine of the vehicle with
the discharged battery, wait for two to
three minutes until the engine "runs"
smoothly.
11. If the eng ine does not start: Stop try ing
after 10 seconds and then try again after
about 30 seconds.
12. In the vehicle that has received start as­
sistance, turn on the heater blower and
the rear window heating to elim inate any
vo ltage peaks when disconnecting . Driv­
ing lights must be switched off!
13 . Disconnect the cable while the engine is
running exactly in
reverse order to that

page 232, Connecting/dis­
connecting the jumper coble ..
When do­
ing so, make sure that the cable cannot
contact rotating eng ine parts.
14. Close the cover on the posi tive terminal.
The battery is vented to the outside to prevent
gases from entering the vehicle inter ior. Make
sure that the jumper clamps are well connect­
ed with their
metal parts in full contact with
the battery terminals.
