the w heel bo lts.
- Pull the reversible blade from the screw­
dr iver before you use the hexagonal
socket in the hand le to turn the wheel
bolts.
- When mount ing tires w ith
unidi rectional
tread design
make sure the tread pat­
tern is po inted the right way
~page 280.
-The wheel bo lts shou ld be clean and easy
to turn. Check for dirt and corrosion on
the mating surfaces of both the wheel

Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the right direction .
Using a sp are t ire wi th a tread pattern
int ended fo r use in a specific dir ect ion
When us ing a spare tire w ith a tread patte rn
intended for use in a specific direction, please
note the following:
- The direction of rotation is marked by an ar­
row on the side of the tire.
- If the spare t ire has to be installed in the in­
correct direction, use the spare tire only
temporarily since the t ire will not be able to
achieve its optimum performance character­
ist ics with rega rd to aquaplaning, noise and
wea r.
- We recommend that you pay particular at­
tent ion to this fact du ring wet weather and
that you adjust your speed to matc h road
conditions.
- Replace the flat tire w ith a new one and
have it installed on your vehicle as soon as
possible to restore the handling advantages
of a unidirectiona l tire .

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 . Thi s appl ies especial ly to the light bu lbs
in the front of your car which you can only
reach through the engine compartment .
Sheet metal and bulb ho lders can have sharp
edges that can cause ser ious cuts, and parts
must be co rrectly 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 resealed.
F or your safety, we recommend that you have
your author ized Audi dealer rep lace any bulbs
for you, since your dealer has the proper tools,
the correct bu lbs and the expertise.
Gas di scharge lamps (Xenon lights):
Due to the high e lectr ica l voltage, have the
bulbs replaced by a qualified technician.
Head lights w ith Xenon light can be identified
by the high voltage sticker .
LED headlights* require no maintenance .
P lease contact your authorized Audi dealer if a
bulb needs to be replaced.
A WARNING
Contact with high-voltage components of
the electrical system and improper re­ placement of gas discharge (Xenon) head­
light bulbs can cause ser ious personal in­
jury and death.
- Xenon bulbs are pressur ized and can ex­
p lode when being changed.
- Changing Xenon lamps requ ires the spe­
cial tra ining, instructions and equip­
ment.
- Only an authorized Audi dealer or other
qualified workshop should change the
bu lbs in gas discharge lamps .
_& 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 wo rk­
shop . Serious personal injury may result
from improperly performed work .
(D Tips
-If you still prefer to replace the light
bulbs yoursel f, be aware that the engine
compartment is a hazardous area to
work in
r=)poge 22Sr=) .&.
-It is best to ask your authorized Audi
dealer whenever you need to change a
bulb .

@ Tips
The discharged battery must be properly
connected to the vehicle's electrical sys­
tem. When jump starting or charging the
battery, never connect the negative
ground cable to the battery negative post
because the batte ry manager system must
be able to detect the battery 's state of
charge. Always connect the negative
ground cab le to the negative ground post
of the battery manager control unit.
Use of jumper cables
Make sure to connect the jumper cable
clamps in exactly the order described below!
