2015 AUDI A5 CABRIOLET open gas tank

Fuel and R efue lin g
Gasoline additives
A major concern among many auto manufactur­
ers is carbon deposit build- up ca used by the type
of gasoline you use.
Although gasoline grades differ from one manu­
facturer to another, they have certa in things in
common. All gaso line grades contain substances
that can cause deposits to collect on v ita l engine
parts, such as fue l 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 T IER Detergent Gas­
oline. For more information on TOP TIER Deter­
gent Gasoline, please go to the officia l website
(www.toptiergas.com).
After an extended period of using inadequate
fue ls, built-up carbon deposits can rob your en­
g ine of peak performance .
CD Note
-Damage or ma lf u nction due to poor fuel
quality is not covered by the Aud i New Vehi­
cle Limited Warranty .
- Do not add aftermarket f uel addit ive prod­
ucts to your fuel tank.
Refueling
Fuel filler neck
The fuel f iller neck is located on the r ight rear
side panel behind the fuel f iller flap .
If the power Locking system should fail, you can
still open the flap manually -for deta iled instruc­
tions seer:>
page 194.
You can find the fue l tank capacity of your vehicle
in r:>
page 246 .
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For more in­
formation about fue l specifications, see
c:> page 190 .
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
192
po lluting the environment while you refuel your
vehicle. In order to fi ll the tank properly while
protecting the environment, please follow this
refueling procedure carefu lly.
A WARNING
Under normal operating conditions, never car­
ry additional fuel containers in your car. Gas
can isters and other containers used to trans­
port fuel can be dangerous. Such containers,
fu ll or empty, may leak and could ca use a fire
in a co llision.
If you must tra nsport f uel to
use for your lawn mower, snow blower, etc.,
be very careful and always observe local and
state laws regarding the use, transportation
and storage of such fue l containers . Make cer­
tain the container meets industry standards (ANSI/ASTM F852 -86).
CD Note
Never drive your vehicle until the fue l tank is
complete ly empty. The irregular supply of
f u el can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.

A WARNING
Improper refueling or handling of fue l can
cause fire, exp losion and severe burns.
-
- Fuel is highly flammable and can cause se­
vere burns and other injuries.
- Failure to shut the engine off whi le refuel­
ing and/or to insert the pump nozzle fu lly
into the fuel filler neck could cause fue l to
spray out of f iller neck or to overflow. Fuel
spray and overflow ing fuel can cause a fire.
- Never use a cellular telephone wh ile refuel­
ing. The electromagnetic radiation can
cause sparks that can ignite fuel vapors and
cause a fire.
- Never get back into your vehicle while refu­
eling. If in exceptional c ircumstances you
must get back in your vehicle while refuel­
ing, make certain that you close the door
and touch meta l to discharge static e lectric­
ity before touching the filler nozzle again.
Fu el and R efu elin g
Static electricity can cause sparks that can
ignite fue l vapors released during refue ling.
- Never smoke or have an open f lame any­
where in or near your vehicle when refueling or filling a portable fuel conta iner .
- For your safety, we strongly recommend
that you do not travel with a portable f uel
container in your veh icle. The container, full
or empty may leak and cou ld cause a fire,
especially in a crash .
- If, under exceptional c ircumstances, you
must transport a portab le fuel container,
please observe the following:
- Never fill a portable fuel container while it
is anywhere in or on the vehicle (for exam­
ple, in the l uggage compartment, or on
the trunk). Static e lectric ity can build up
while filling and can ignite fuel vapors
caus ing a fire .
-Always place a portab le fue l conta iner on
the ground before fill ing .
- Always keep the filler nozzle completely
inside the portable container before and
during f il li ng.
- If filling a portab le container made of
metal, the f iller nozzle must always be in
contact with the container. This will help prevent static electricity from d ischarging
and cause a fi re.
- Never spill fuel inside the vehicle or lug­
gage compartment. Fuel vapors are highly
flammable.
- Always observe local and state/provincial
laws regarding the use, storage and trans­
po rtation of fue l conta iners.
- Make certain the fuel conta iner meets in­
dustry standards (ANSI/ AS TM F852 -86).
(D Note
If any fuel has sp illed onto the car, it should
be removed immediately to prevent damage
to the pa int.
