-If you are unable to determine whether or
not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identified.
- Fuel system damage and performance prob­
lems 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 major concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasoline grades differ 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, carbon deposit build-ups can rob your
en­
gine of peak performance.
(D Note
Damage or malfunction due to poor fuel qual­
ity is not covered by the Audi New Vehicle
Limited Warranty.

Emissions control
system
Cat alytic con verter
The vehicle may only be driven with unleaded
gasoline, otherwise the catalytic converter will be
destroyed.
Never drive until the tank is completely empty .
The irregu lar supply of fuel that results from that
can cause engine misfires. Uncombusted fuel will
enter the exhaust system, which can cause over­
heating and damage to the catalytic converter .
A WARNING
The temperature of the exhaust system is
hi gh, both when driv ing and after stopping
the eng ine.
-
- Never touch the exhaust tail pipes once they
have be come hot. This cou ld resu lt in burns.
- Do not park your veh icle over flammable
mate ria ls such as grass or leaves because
the high temperature of the emissions con­
trol system could start a fire.
- Do not app ly unde rbody protectant in the
exhaust sys tem area, beca use this increases
the risk of f ire.
On Board Diagnostic
System (OBD)
The On-Board Diagnostic System monitors the
engine and transmission components that influ­
ence emissions .

cases, other parts of the ca r must fi rst be re­
moved before you a re able to get to the bu lb.
This applies espec ially 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 lde rs can have sha rp
edges that can cause ser ious cuts, parts must be
correct ly taken apart and then properly put back
together to he lp prevent breakage of parts and
long term damage from water that can enter
housings that have not been properly resea led.
