open gas tank AUDI Q3 2015 Owners Manual

176 Fuel suppl y and fillin g your fu el tank
Many gaso line grades are blended to perform
especially we ll for winter or summer driving.
During seasonal change-over, we suggest that
you fill up at busy gas stations where the sea­ sonal adjustment is more likely to be made in
time.
@ Note
- Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo ­
nents in the fuel system.
- Do not use fuels that fail to meet the
spec ified criter ia in this chapter .
- If you are unable to determine whether
or not a particular fuel blend meets the
spec ificat ions, ask your service station o r
i ts fuel supplier .
- Do not use fuel for wh ich the contents
cannot be identified .
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the respons ibility of Audi and are not
covered under the New Ve hicle or the
Emission Control System Warranties.
- If you experience a loss of fue l economy
or driveabil ity and performance prob­
l ems due to the use o f one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
A major concern among many auto manufac­
turers is carbon deposit build-up caused by
the type of gasoline you use .
A lthough gasoline grades diffe r from one
manufac turer to another, they have certa in
things in common. All gasoline grades contain
substances that can cause depos its to collect
on vital engine parts, such as fuel injectors
and intake valves . Although most gasoline
b rands include additives to keep eng ine and
fuel systems clean , they are not eq ua lly effec­
tive. Audi recommends using
TOP TIER Detergent
Gasoline . For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas .com) .
After an extended period o f using inadeq uate
fuels, built-up carbon deposits can rob your engine of peak performance.
(D Note
- Damage or malfunction due to poor fuel
quality is not covered by the Audi New
Vehicle Limited Warranty .
- Do not add afte rmarket fuel additive
produc ts to your f uel tank .
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
s ide panel behind the fuel filler flap.
If the power locking system should fail, you
can still open the flap manually -for detailed
instruct ions see o page 178.
You can find the fuel tank capacity of your ve­
hicle in
o page 235 .
The label on the inside of the f uel fi ller flap
te lls you the correct fue l for your vehicle. For
more information about fue l specifications,
see
c:;, poge 175.
Your vehicle fue l tank has an on -board refuel­
ing vapor recovery system . This feature helps
to prevent fuel vapors from escaping from the
tank and pollut ing the environment while you
refuel your vehicle. In order to fill the tank
properly while protecting the environment,
please follow this refueling procedure careful­
ly.
.&_ WARNING

cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injur ies .
