-Fuel system damage and performance prob­
l ems resulting from the use of fuels differ­
ent from those specified are not the respon­
sibility of Audi and are not covered under
the New Vehicle or the Emission Control
System Warranties.
- If you experience a loss of fuel economy or
driveability and performance problems due
to the use of one of these fuel blends, we
recommend that you switch to unblended
fuel.
Gasoline additives
A majo r concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasoline grades d iffer from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vital engine parts, such as fuel injectors and intake valves . Al­
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP TIER Detergent Gas­
oline . For more information on TOP TIER Deter­
gent Gasoline, please go to the official website
(www.toptiergas.com).
After an extended period of using inadequate
fuels, built-up carbon deposits can rob your en­ gine of peak performance.

-Damage or malfunction due to poor fuel
quality is not covered by the Audi New Vehi ­
cle Limited Warranty.

A WARNING
An improper fue ling procedure and improper
hand ling of fue l can lead to explosions, f ires,
severe bu rns and other injur ies.
- Do not smoke and keep away from open
flames.
- The ignition must be switched off when re­
fueling .
- Cell phones, radio devices and other radio
equipment should always be switched
off
when refueling. Electromagnet ic rays cou ld
cause sparks and start a fire.
- If you do not insert t he fue l pump nozzle a ll
the way into the filler tube, then f ue l can
leak out. Spilled fuel can ignite and start a
fire .
- Never get into the vehicle when refueling. If
there is an exceptional situation where t he
vehicle must be entered, close the door and
touch a metal surface before touching the
fuel pump nozzle agai n. This will reduce the

fuel containers in the vehicle . Fuel could leak
out of t he container and ignite, especially dur-

- Fo r fuel con tai ners made o f me tal, the
fuel p ump nozzle must a lways maintai n
contact with the container to reduce the
risk of stat ic charge.

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
