• Align the jack so that the jack arm claw
c:;, fig. 186 @fits snugly around the unde r­
body rib and the movab le base plate ® sits
flat on the ground. The base @ must be
ver­
tical
under the lifting point @.
• Wind the jack up further until the flat wheel
comes off the ground

Recesses at the front and rear of the under­
body rib mark the proper mo unting locations
for the jack
c:;, fig. 185 . There is only one des­
ignated jack mounting po int for each wheel.
Do not apply the jack anywhere else c::> .&. .
The jack shou ld be positioned approximate ly
6 in. (15 cm) behind the front wheel or 10 in.
(25 cm) in front of the rear wheel.
An
unstable surfa ce under the jack can cause
the vehicle to slip off the jack . Always provide
a firm base for the jack on the ground . If nec­
essary place a sturdy board or sim ilar support
under the jack. On
hard , slipper y su rf a ces
(such as tiles) use a rubber mat or similar to
prevent the jack from slipp ing

After you have loosened all wheel bolts and
jacked the vehicle off the ground, perform the
following steps to remove and replace the
wheel:
Removing the wheel
.,. Use the hexagonal socket in the screwdriv·
er handle
to completely turn out the top­
most wheel bolt and set it aside on a
clean
surface c;, fig. 187 .
.,. Screw the threaded end of the alignment
pin from the tool kit hand-tight into the
now vacant bolt hole <=>
fig. 188 .
.,. Then completely unscrew the other wheel
bolts as described above.
.,. Take off the wheel leaving the alignment
pin in the bolt hole
c;, &,.
Putting on the spare
.,. Lift the spare wheel up and carefully slide it
over the alignment pin to guide it in place .
.,. Use the hexagonal socket in the screwdriver
handle to screw in and tighten all wheel
bolts
slightly .
.,. Unscrew the alignment pin and insert and
tighten the remaining wheel bolt slightly
like the rest.
.,. Turn the handle on the jack counter-clock­
wise to lower the vehicle until the jack is
fully released .
.,. Use the wheel bolt wrench to tighten all
wheel bolts firmly
r:::;, page 238 . Tighten
them
crosswise , from one bolt to the (ap­
proximately) opposite one, to keep the
wheel centered.

A WARNING ,~ -
When removing or install ing the wheel,
the rim could hit the brake rotor and dam­
age the rotor. Work ca refully and have a
second p erson help yo u.

the right direction.
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spare tire wit h a tread pa tte rn
intended for use in a specific direction , pl ease
note the following:
- The direc tion o f rota tion is marked by an a r­
r ow on the side o f the tire.
- If the spare tire has to be i nst alled in the in ­
correct di rection in the even t of a flat tire,
use the spare tire on ly tempo rari ly since the
tire will not be ab le to ac hieve its opt imum
per formance characterist ics w ith regard to
aquapla ning, no ise and wear.
- We recommend that particular attent ion be
paid to this fact dur ing wet weather and
t h at you adjust your speed to matc h road
co ndit io ns.
What do I do now? 241
- Replace the flat ti re with a new one and

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 ca r which you can only
reach through the engine compartment.
Sheet metal and bulb holders can have sharp
edges that can cause serious cuts, and parts
must be cor rectly taken apart and then prop­
erly 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 re sea led.
For your safety, we recommend that you have
your authorized Audi dea ler replace any bulbs
for you, since your dealer has the proper tools,
the correct bulbs and the expertise.
Gas discharge lamp s (Xenon lights)*:
Due to the high e lectr ica l voltage, have the
bulbs replaced by a qualified techn ic ian.
Head lights with Xenon light can be identified
by the high voltage sticker.
_& WARNING ~
Contact with high-vo ltage 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 pressur ized and can ex­
plode when being changed.
- Changing Xenon lamps requires the spe­
cial tra ining, instructions and equip­
ment.
- On ly an authorized Audi dealer or other
qualified workshop should change the bulbs in gas discharge lamps .
