open gas tank AUDI TT ROADSTER 2015 Owners Manual

Many gasoline grades are blended to perform
especia lly 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.
Q;) 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 or
i ts fuel supplier .
- Do not use fuel for which 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 Vehicle or the
Emission Control System Warranties.
- If you experience a loss of fue l economy
or driveability and performance prob­ l ems 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 manufac­
turers is carbon deposit build-up caused by
the type of gasoline you use .
Although gasoline grades differ from one manufacturer to another, they have cer tain
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. Although most gasoline
brands include additives to keep engine and
fuel systems clean, they are not equally effec­
tive.
Fuel supply and filling your fuel tank 161
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 of using inadequate
fuels, built -up carbon deposits can rob your
engine of peak performance.
CJ) Note
Damage or malfunction due to poor fuel
quality is not covered by the Audi New Ve­
hicle Limited Warranty.
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 unlocking system should fail, you can
still open the flap manually -for detailed in­
structions see
~ page 163.
You can find the fuel tank capacity of your ve ­
hicle in
~page 223 .
The label on the inside of the fuel filler flap
tells you the correct fuel for your vehicle. For
more information about fuel specifications,
see
~ page 160 .
Your vehicle fuel tank has an on-board refuel­
ling 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.
A WARNING ~
Under normal operating conditions, never
carry additional fuel containers in your car.
Gas canisters and other containers used to
transport fuel can be dangerous. Such con­
tainers, full or empty, may leak and could
cause a fire in a collision . If you must
transpo rt fuel to use for your lawn mower, ..,.
