_& WARNING
Impr oper use of the vehicle jack can cause se­
rious personal injur ies.

- The factory-supp lied jack is intended only
for your vehicle mode l. Under no circum­
stances should it be used to lift heavy
veh icles or other loads; you risk injuring

Emergency assistance
"'Secure the collapsible spare tire with the hand -
whee l.
"'Fo ld the cargo floor cover back into p lace.
Snow chains
Using snow chains on the collapsible spare tire is
not permitted for technical reasons.
If you have to drive with snow chains and a front
tire fa ils, mount the collapsible spare tire in
p la ce of a rear tire. Insta ll the snow cha ins on the
rear tire that you removed, and install that in
p lace of the front tire that failed.
A WARNING
-
- Only use the collapsible spare tire in emer ­
gencies and drive very carefully, especially if
it is more than six years old .
- The compressor and the hose can become
very hot during operation which increases
the risk of burn injuries.
- After installing a collapsible spare tire, the
t ir e pressure must be checked as quickly as
poss ible to reduce the risk of an acc ident.
- Do not drive faster than 50 mph (80 km/h)
with a collapsible spare tire. Driving faster
than that increases the risk of an accident .
- Avoid full-throttle acceleration, heavy brak­
ing, and fast cornering with the collapsible
spare tire, because this increases the risk of
an accident .
- Never drive using more than one collapsible
spare tire, because this increases the risk of
an accident.
- Normal tires or winter tires must not be
mounted on the collaps ible spare tire rim.
«J:) Note
The compressor must be switched off after 12
minutes at the most to reduce the risk of
overheating . Let the compressor cool down
for several minutes before using it again.

Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any 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 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 serious cuts, parts must be
correctly taken apart and then properly put back
together to help prevent breakage of parts and
l ong term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend that you have
your author ized Audi dealer replace any bulbs for
you, s ince your dealer has the proper tools, the
correct bulbs and the expert ise.
Fuses and bulbs
Gas discharge lamps (Xenon lights) :
Due to the high e lectr ical voltage, have the bulbs
replaced by a qualified technician. Headlights
with Xenon light are identified by the high volt­
age sticker .
LED headlights*
LED headlights require no maintenance. Please
contact your authorized Audi dealer if a bulb
needs to be replaced .
.&, WARNING
Changing Xenon lamps without the necessary
equipment can cause serious personal injury.
- Bulbs are pressurized and can explode when
be ing changed. Potential risk of injury!
- On veh icles equipped with gas discharge
bu lbs (Xenon light) life-threatening injuries
can resu lt from improper handling of the
h ig h-vo ltage portions of such lamps!
- Only your authorized Audi dealer or quali­
fied workshop should change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the
bulb holders that can cause serious cuts. If
you are uncertain about what to do, have the work performed by an authorized Audi
dealer or qualified workshop. Ser ious per­
sonal injury may result from improperly per­
formed work.
(D Tips
- If you st ill prefer to replace the light bulbs
yourself, be aware that the engine compart­ ment is a hazardous area to work
in¢ A in
Working in the engine compartment on
page 323.
- It is best to ask your authorized Audi dealer
whenever you want to change a bulb .

Consumer Info rmation
today's a utomo biles, have steadily reduced the
scope of maintenance and repairs which can be
carried out by veh icle owners.
Also , sa fet y and
en vironmental
concerns place very strict limits
on the nature of repairs and adjustmen ts to en­
g ine and transmission parts wh ich an owner can
perform .
Maintenance, adjustments and repairs usually re­
qu ire special tools, testing devices and other
equ ipment available to specially trained work ­
shop personnel in order to assure proper per­
forma nce, re liability and safety of the veh icle and
its many systems .
Improper maintenance, adjustments and repairs
can impair the operation and reliab ility of your
ve hicle and eve n void your vehicle warranty .
Therefo re, proof of se rvicing in a ccordance w ith
the m aintenance sched ule may be a condition for
up ho ld ing a possible wa rranty claim made within
the wa rranty pe riod.
Above all , ope rational safety can be adversely af­
fected, cre ating unne cessa ry risks fo r you and
your passengers.
I f in doubt about any servicing, have it done by
your author ized Audi dealer or any other properly
eq uipped and qualified workshop . We strongly
urge you to g ive your author ized Audi dealer the
opportunity to perform a ll scheduled mainte ­
nance and necessa ry repairs. Your dealer has the
