After changing a wheel
A wheel change is not complete without the following
actions.
-Store and secure the replaced wheel in the spare wheel
well.
-Put the tool case and the jack back in place in the luggage
compartment.
-Check the tire pressure on the spare wheel immediately
after mounting it.
- As soon as possible, have the
tightening torques on all
wheel bolts checked with a torque wrench. The correct
tightening torque is
90 ft lb (120 Nml.
- Have the flat tire
replaced as soon as possible.
[ i] Tips
• If you notice while changing a tire that the wheel bolts are
corroded and difficult to turn, then they should be replaced before
you check the tightening torque.
• Drive at reduced speed until you have the tightening torques
checked .•

- Switch off the ignition and the electrical component
affected.
- Carefully pry the face cover off the instrument panel
using the ignition key or a
screwdriver ~ fig. 232.
- Check the fuse listing on the next pages to find out which
fuse belongs to the component which has failed
~ page 327, "Fuse list".
- Remove the blown fuse with the plastic clip provided.
The clip is located on the holder in the fuse box.
- Replace a blown fuse (recognizable by the melted metal
strip inside) with a fuse of the same amperage .
- Firmly snap the cover back onto the instrument panel
face.
The various electrical circuits are protected by fuses. The fuses are
clustered in a centralized unit. The unit is located behind the face
panel at the end of the instrument panel. The crank for operating
the sunroof in case of a power failure is also stored behind the face
panel ~ page 70.
Two spare fuses and a sticker identifying the fuses are located on
the inside of the fuse box cover.
You are well advised to keep a supply of spare fuses in your vehicle.
Fuses with the proper ampere ratings are available at your Audi
d ea le r.
& WARNING
Never replace a fuse with one that has a higher amperage rating.
• A fuse with a too high amperage could damage the electrical
part and cause a fire.

Bulbs
A pplies to vehicle s: wit h xenon he ad ligh ts
Replacing light bulbs
For your safety, we recommend that you have your autho ­
rized Audi dealer replace any bulbs for you.
I t is becoming increasing ly more and more difficult t o replace
vehic le light bulbs since in many cases, other parts of the car must
first be removed before yo u are able to get to the bu lb . T his applies
especia lly to the ligh t bu lbs in the front of your car which you can
only reach th rough the eng ine compartment.
Sheet metal and bulb ho lders can have sharp edges that can cause
s e rious cuts, and parts must be correctly taken apart and th en prop­
erly put back together to help prevent breakage of par ts and long
te rm damage from water that can enter housings that have not
been properly resealed .
For your safety , we recommend that you have your authorized Audi
dea ler replace any bulbs for you, since your dealer has the prope r
tools, the correct bulbs and the expertise .
Gas di sc harge l amp s (x enon l ight s)*:
Due to the h igh e lectrical voltage, have t he bu lbs replaced by a qual ­
ified technician . Head lights with xenon light are identified by the
high voltage sticker .
& WARNING
Changing xenon lamps without the ne cessary equipment c an
c au se seriou s per sonal injury .
• Bulb s are pres surized and can explode when being changed.
Potential ri sk of injur y!
• On vehicle s equipped with ga s di scharge bulb s (xenon ligh t)*
life -threaten ing injurie s can re sult from impr oper h andling of the
high -voltage portion s of su ch lamp s!
