Bulbs
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 .
T his applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment .
Sheet metal and bu lb holders can have sharp
edges that can cause serious cuts, pa rts must be
correctly taken apart and then properly put back
together to help prevent breakage o f parts and
long term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend that you have
your authorized Aud i dea ler rep lace any bulbs fo r
you, since your dealer has the proper tools, the
correct bulbs and the expertise.
Gas di schar ge la mps (Xe no n ligh ts):
Due to the high electr ical voltage, have the bulbs
rep laced by a qualified technician. Headlights
with Xenon light are identified by the hig h volt­
age st icker.
LED headlights* require no maintenance . Please
contact your authorized Audi dea ler if a bulb
needs to be replaced.
_&. WARNING
Changing Xenon lamps wi thout the necessary
equipment can cause serious personal injury .
- Bulbs are pressu rized and can explode when
be ing changed. Potent ial ris k of injury!
- On veh icles equipped with gas disc harge
bu lbs (Xenon light) life-threatening injuries
can resu lt from improper handling of the
high-vo ltage portions of such lamps!
- Only your authorized A udi dealer or quali­
f ied workshop sho uld change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the

Operating your vehicle
outside the U.S.A. or
Canada
Government regulati ons in the United States and
Canada require that automobi les meet specific
emission regulations and safety standards.
Therefore, vehicles built for the U.S.A. and Cana ­
da differ from vehicles sold in other countries.
If you plan to take your vehicle outside the conti­
nenta l limits of the United States or Canada,
there is the poss ibility that:
- un leaded fue ls for vehicles with catalytic con­
verter may not be available;
- fuel may have a considerably lower octane rat­
ing . Improper fuel may cause engine damage;
- service may be inadequate due to lack of proper
service facilities, tools or testing equipment;
- r eplacement parts may not be readily available.
- Nav igation systems for veh icles built for the
U.S .A . and Canada will not necessarily work in
Europe, and may not work in other countries
outside of North America.

Maintenance
General '
Your vehicle has been designed to help keep
maintenance requirements to a min imum. How­
ever, a certain amount of regular maintenance is
still necessary to assure your vehicle's safety,
economy and reliability . For detailed vehicle
maintena nce consult your Warranty & Mainte­
nance booklet .
Under difficult operating conditions, for exam ­
ple at extremely low outside temperatures, in
very dusty regions, whe n towing a trailer very fre­
quently, etc., some service work should be per­
formed between the intervals specified. This ap­
plies particularly to:
- oil changes, and
- cleaning or replac ing the a ir filter .
'
@) For the sake of the environment
By regularly maintain ing your vehicle, you
help make sure that em iss ion standards are
maintained, thus minimizing adverse effects
on the environment .
Important considerations for you and your
vehicle

fuel injection and emission control systems, and
the genera lly increas ing technica l complexity of ..,_

Consumer Info rmation
@ For the sake of the env ironment

affect emission levels. Th is is detrimental to
the environment and increases fuel con­
sumption.
- A lways observe environmental regu lations
when disposing of old engine o il, used brake
fl ui d, d irty engine coolant, spent batteries
or worn out tires.
- Undeployed airbag modules and pretension­
ers mig ht be classified as Perchlorate Mate­

minum/Carbon F iber (Ultra Advanced L ight
We ight Materials) are as un ique as the ir drivers.
Therefore, the availability of certain parts needed
for repair, restoration, or reconstruction will be
rest ricted, or pa rts will be unava ilable, if the ve­
h icle is not repaired at an a uth orized Aud i co lli ­
sion repair facility . This includes but is not limit ­
