Gasoline additives
App lies to: vehicles with gasoline engine
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 gasolin e brands include additives to
keep engine and fuel systems clean, they are not
equally effe ctive.
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 depos its can rob your en-
gine of peak performance.

quality is not covered by the Audi New Vehi-
cle Limited Warranty .
- Do not add aftermarket

ucts to your fuel tank.
Diesel fuel
Applies to: vehicles with diesel eng ine
Always use ULSD (Ultra Low Sulfur Diesel) No.
2.
The ULSD No .
2
meets the ASTM
0975.
Diesel fuel with concentrations
of biodiesel high-
er than S % such as 811,820
or 8100 are strictly
prohibited.
Service station fuel pumps are labeled with the
correct fuel information
for easy recognition
by
the user. If the diesel fuel pump is not labeled
ask the station operator what fuel is being dis-
pensed before filling up your vehicle .
ULSD No. 2 may not be available outside the USA
and Canada. Be sure to check before traveling to
other countries.
Fuel and Refueling
ULSD No. 2 can become thicker in very cold tem-
peratures,
and this can impair the engine 's start-
ing and running. Depending on the season, gas
stations
provide ULSD No. 2 that flows better in
cold temperatures
so tha t you can continue oper-
ating your vehicle as usual.
CD
Note
- Your vehicle's diesel engine was designed
soley for use with ULSD No.
2.
Therefore,
never use gasoline, heating oil, other fuels
or flow improvers . These contain substances
that will severely damage the fuel system
and the engine. Such damage will not be
covered by your New Vehicle Limited War-
ranty.
- If you put any amount of incorrect fuel in
the fuel tank, do not start the engine under
any circumstances.
Immediately
contact the
nearest authorized
Audi dealer or author-
ized Audi Service Facility for assistance.
These fuels contain substances
that can se-
verely damage the fuel system and the en-
gine if the engine is started .
Refueling
Fuel filler neck

side panel behind the fuel filler flap.
If the power locking system should fail, you can
still open the flap manually - for detailed instruc-

Your vehicle fuel tank has an on-board refuelling
vapor recovery system. This feature helps to pre-
vent fuel vapors from escaping from the tank and
polluting the environment
while you refuel your
vehicle. In order to fill the tank properly while
protecting
the environment,
please follow this
refueling procedure carefully.
