page 18 and ¢ page 28 . Do not
continue to operate the vehicle. The complete brake system should be thoroughly checked by an
author ized Audi dealer or qualified workshop and
the cause corrected . If the brake fluid level is too
low, the brake warning/ind icator light will illumi
nate. Contact an authorized Audi dealer
immedi

Changing brake fluid
Have the brake fluid changed by an experienced technician.
Brake fluid absorbs mo isture from the air. If the
water conte nt in the brake fluid is too h igh, cor
ros ion in the brake system may resu lt after ape
riod of time. The boiling poi nt of the brake flu id
will also dec rease cons iderably and decrease
braking pe rformance.
Therefore, the b rake fluid must be changed
e ve ry
two year s.
Always use new b rake fluid wh ich con
forms to Fede ral Motor Veh icle St andard "FMVSS
116 DOT 4".
The brake fluid reservoir can be diff icult to reach,
therefore, we re commend that yo u have the
b rake fl uid changed by yo ur autho rized
Audi
deal er.
Your dealer has the cor rect too ls, the
right brake fluid and the know -how to do this for
you.
A WARNING
- Brake fluid is poisonous. It must be stored
only in the closed original container out of
the reach of chi ldren!
- B rake failure can resu lt from old or inappro
pr iate brake flu id. Observe these precau
t io ns:
Ch eck ing and Filling
-Use only brake fluid that meets SAE speci
ficat ion
J 1703 and conforms to Federal
Motor Vehicle Standard 116. Always check
with your authorized Aud i dealer to make
sure you are us ing the correct brake fluid .
The co rrect type of brake flu id is also i ndi
cated on the b rake fluid reservoir.
- The brake flu id must be new. Heavy use of
the b rakes can cause a vapo r lock if the
bra ke fluid is left in the system too long.
T his can se riously affe ct the efficiency of
t h e b rakes as we ll as you r safety . This
could resu lt in an accident.
(D Note
B rake flu id will damage the paint of your ve h i
cle.
@) For the sake of the environment
Because of the p roblem of proper d isposa l of
brake fluid as well as the spec ial too ls re
q uire d and the necessary expertise, we rec
ommend that yo u have the bra ke fluid
c hanged by yo ur authorize d Au di dealer.

Emergency assistance
Performing the repair
Applies to vehicles: w ith tire repair k it
Fig. 215 Performing the repair
Preparations
.,. Park the vehicle as far as possible from moving
traffic in the event of a flat tire.
.,. Set the
parking brake to prevent the vehicle
from rolling unintentionally.
.,. Shift the
selector lever into the P position.
.,. Determine whether a repair with the tire repair
kit is possible or not¢
page 257.
.,. Let all of the passengers
exit the vehicle and
move a safe distance away¢_&. .
.,. Take the
sealant bottle and the compressor
out of the luggage compartment ¢ page 104,
fig. 115.
.,. Affix the label "max. 50 mph (80 km/h)", found
on the sealant bottle, to the instrument cluster
where it can be seen by the driver.
Filling a tire
.,. Shake the bottle thoroughly before filling.
.,. Screw the accompanying filling hose complete
ly onto the bottle. This breaks through the foil
seal automatically at the connection .
.,. Remove the valve cap from the tire valve and
unscrew the valve insert using the accompany
ing valve insert tool
~fig. 215.
.,. Lay the valve insert on a clean surface .
.,. Remove the sealing plug from the filling hose
and connect the hose to the tire valve .
.,. Hold the bottle with the bottom facing upward
and empty the entire contents into the tire .
.,. Then pull out the hose and screw the valve in
sert tightly back into the tire valve.
258 Inflating a tire
.,.
Screw the filling hose for the compressor onto
the tire valve and insert the connector into the
cigarette lighter.
.. Inflate the tire to between 29 PSI (200 kPA)
and 36 PSI (250 kPA) and read the pressure on
the gauge .
.,. If this tire pressure is not reached, drive your
vehicle approximately 33
ft (10 meters) for
ward or backward so that the sealant can be re
distributed inside the tire. If at this time the re
quired air pressure still cannot be reached, the
tire is too badly damaged and cannot be re
paired with the tire sealant.
Final inspection
.,. Stop the vehicle after driving for about 10 mi
nutes and check the tire pressure.
.,. If the tire pressure is lower than 19 PSI
(130 kPA), then the tire is too severely dam
aged. Do not continue driving. Please seek pro
fessional assistance .
&_ WARNING
- Turn on the emergency flashers if you have a
flat tire while in moving traffic. This is for
your protection and the for the safety of
other drivers.
- Take care to move all of the passengers to a
safe place (behind a guard rail for example) .
- Read and follow the manufacturer's safety
precautions on the compressor and in the instructions on the bottle of sealant!
- If a tire pressure of 29 PSI (200 kPA) cannot
reached after inflating for 12 minutes, then
the tire is too severely damaged. Do not
continue driving.
- Obtain qualified help if it is not possible to
perform the repair with the tire sealant .
- If the tire pressure is less than 19 PSI
(130 kPA) after 10 minutes of driving, then
the tire is too severely damaged . Do not
continue driving. Seek professional assis
tance .

Special care is required if you are repairing
the tire on a steep incline.
@ Tips
- Do not operate the compressor for more
than 12 minutes continuously, otherwise it
can overheat. Once the compressor has
cooled, you can continue to use it.
- If sealant has spi lled out, let it dry and then
you can remove it by peeling it away like a
foil.
- Remember to obtain a new bott le of sealant
from your authorized Audi dealer after re
pair ing a tire. After this, the functionality of
the tire repair set is restored .
- Obey all laws.

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 diffi
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re
moved before you are able to get to the bu lb.
This applies espec ially to the light bulbs in the
front of your ca r wh ich you can only reach
through the eng ine compartment.
2 6 8
Sheet meta l and bu lb holders can have sharp
edges that can cause serious cuts, and parts
must be correctly taken apart and then properly
put back together to help prevent breakage of
parts and long term damage from water that can
enter housings that have not been properly re
sealed.
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.
Ga s d ischar ge lam ps (Xeno n light s)*:
Due to the high e lectrica l voltage, have the bulbs
rep laced by a qualified technician. Headlights
with Xenon light can be identified by the h igh
voltage sticker.
A WARNING
-
Contact with high-voltage components of the
electr ical system and improper replacement
of gas discharge (Xenon) headlight bulbs can
cause ser ious persona l injury and death .
- Xenon bulbs are pressur ized and can ex
plode when being changed .
- Changing Xenon lamps requires the special
tra ining, instruct ions and equ ipment .
- 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 open
ings and on the bulb ho lders that can cause
serious cuts.
- If you are uncertain about what to do, have
the wor k performed by an authorized Audi
dea ler or other qual ified workshop. Ser ious
personal injury may resu lt from improperly
performed work .
(D Tips
-If you must replace the light bulbs you rself,
always remember that the eng ine compart
ment of any vehicle is a hazardous area to
work in. Always read and heed all WARN
