2014 AUDI TT ROADSTER open gas tank

162 Fuel supply and filling your fuel tank
Many gasoline grades are blended to perform
especially well 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
specified criteria in this chapter .
- If you are unable to determine whether
or not a particular fuel blend meets the
specifications, 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 responsibility 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
lems 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 diffe r from one
manufac turer 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. Although most gasoline
brands include additives to keep engine and
fuel systems clean, they are not equally 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 of using inadequate
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 Ve­
hicle Limited Warranty.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side 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 164.
You can find the fuel tank capacity of your ve­
hicle in~
page 224 .
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 161 .
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 polluting 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 ~
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
transport fuel to use for your lawn mower, ..,.

snow blower, etc., be very careful and al­
ways observe local and state laws regard­
ing the use, transportat ion and storage of
such fuel containers. Make certain the con­ t ainer meets industry standards (ANSI/
AS TM F8S2 -86).
(D Note
Never drive your vehicle unti l the fuel tank
is completely dry. The irregular supply of
fue l can cause misfir ing. Gasoline cou ld
enter into the exhaust system and damage
the cata lytic conve rter.

Refuelling procedure
.,. Insert the fuel nozzle from the g asoline
pump into the fuel fi ller neck as far as it wi ll
go .
.,. Select a med ium refuelling rate so that the
nozz le switches off automatically when the

A WARNING
Improper refue ling or handling of fuel can
cause fire, explosion and severe burns.
- Fue l is highly flammable and can cause
severe burns and other injur ies.
- Failure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fue l to spray o ut of filler neck or to over­
flow. Fue l spray and overflowing fuel can
cause a fire.
- Never use a ce llu lar telephone while re­
fue ling. The electromagnet ic rad iat ion
can cause sp arks that can ignite fuel va­
pors and cause a fire.
- Never get back into yo ur vehicle while re­
fue ling.
If in excep tional circumstances
you must get back in your vehicle while ref ueling, make certain that you close
the door and touch metal to discharge
static electricity before touching the fill­
er nozzle again. Static electr icity can
cause sparks that can ignite fuel vapors
released during refue ling.
- Never smoke or have an open flame any­
where in or near your veh icle when refu­
eling or filling a portab le fuel conta iner.
- For your safety, we strongly recommend
that you do not t ravel with a portable
