refuelling AUDI A5 CABRIOLET 2017 Owners Manual

Fuel and R efue li ng
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 d iffer from one manu­
facturer to another, they have certain things in
common. All gasoline 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 addit ives to
keep engine and fuel systems clean, they are not
equally effective.
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
fue ls, built-up carbon deposits can rob your en­
g ine of peak performance.
CD Note
- Damage or ma lfunction due to poor fuel
quality is not covered by the Audi New Vehi­
cle Limited War ranty.
- Do not add afterma rket fuel add it ive prod­
ucts to yo ur fuel tank.
Refueling
Fuel filler neck
The fuel filler 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 detailed instruc­
tions see
c:> page 192 .
You can find the fuel tank capacity of your vehicle
in
c:>page 244 .
The label on the inside of the fuel filler flap tells
you the correct fue l for your vehicle. For more in­
formation about fuel specifications , see
c:>page 188 .
Your veh icle fuel tank has an on-board refuelling
vapor recovery system . This feature he lps to pre­
vent fuel vapors from escaping from the tank and
190
po lluting the environment whi le you refuel your
veh icle. In order to fill the tank proper ly while
protecting the env ironment, please follow th is
refueling procedure carefully.
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 fue l can be dangerous. Such containers,
f ull or empty, may leak and could cause a fi re
in a co llision.
If you mus t transport fuel 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 fuel containers. Make cer­
tain the container meets industry standards
(ANSI/ASTM F852 -86) .
CD Note
Never drive your vehicle until the fuel tank is
complete ly empty. The irregular supply of
fuel can cause misfiring. Gasoline could enter the exhaust system and damage the catalytic
converte r.

Refuelling proc edure
.,. Inse rt the fue l nozzle from the gasoline pump
into the fuel filler neck as far as it will go .
.,. Se lect a medium refuelling rate so that the
nozzle switches off automatically when the
tank is full.
Putting the fuel cap back on
.,. After filling your tank, tw ist the f uel cap clock-

A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe b urns.
-
- Fuel is highly flammable and can cause se­
vere burns and other injur ies .
- Failure to shut the engine off wh ile refuel ­
ing and/or to insert the pump nozz le fully
into the fuel filler neck could ca use fue l to
spray out of filler neck or to ove rflow. Fuel
spray and overflowing fue l can cause a fire.
- Never use a cellular telephone wh ile refuel­
ing. The electromagnetic radiation can
cause spa rks that can ignite f uel vapors and
cause a fire .
- Never get back into your vehicle while refu­
eling. If in except ional circumstances you
must get back in your vehicle while refuel­
ing, make certain that you close the door
and touch meta l to discha rge static ele ctric­
ity befo re touching the filler noz zle ag ain.
Fuel and R efueling
Stat ic electricity can cause sparks that can
ignite fue l vapors released during refueling.
- Never smo ke or have an open flame any ­
where in or near your vehicle when ref ueling
or filling a portable fuel container .
- For your safety, we strongly recommend
that you do not trave l with a po rtable fuel
container in your veh icle. The container, fu ll
or empty may leak and co uld cause a fire,
especially in a crash .
- If, under except ional circumstances, you
m ust transport a portable fuel container,
p lease observe the following:
- Never fill a portab le fue l conta iner while it
is anywhere in or on the vehicle (for exam­
ple, in the l uggage compa rtment, o r on
the trunk). Static electricity can build up
while filling and can ignite fuel vapors caus ing a f ire .
-Always place a portab le fue l conta iner on
the ground before fi lling .
-A lways keep the f iller nozzle comp lete ly
inside the portable container before and
during f il li ng.
- If filling a portable conta iner made of
metal, the filler nozz le must always be in
contact with the container . This will he lp
prevent stat ic elec trici ty from discharging
and ca use a fire .
- Never spill fue l inside the vehicle o r lug­
gage compartment. F uel vapors a re highly
flammable .
- Always observe loca l and state/prov incial
laws rega rding the use, storage a nd trans­
po rtation of fuel contai ners.
- Make ce rtain the f uel con tainer mee ts i n­
dust ry standards (A NSI/ AS TM F852 -86) .
(D Note
If any fuel has sp illed onto the car, it should
be removed immed iately to p revent damage
to the pa int.
@) For the sake of the environment
As soon as the correctly operated nozzle
switches off automatically for the first time,
191

Fuel and Refueling
the tank is full . Do not try to add more fuel
because fuel may spill out. In addition, the
expansion space in the fuel tank will be filled -
causing the fuel to overflow when it becomes
warm and pollute the environment.
(D Tips
- Running your engine while refuelling may
cause vapors to escape or even cause fuel to
sp ill out of the tank. This would then shut
off the fuel nozzle before the tank is full.
- Do not refuel your vehicle with the ignition
turned on. The fuel gauge may otherwise
not indicate the correct fuel level after refu­
elling.
- The fuel filler flap of your vehicle is not
l ocked when you lock the veh icle from the
inside .
Unlocking the fuel filler flap by hand
You con open the fuel filler flop by hand if the
power locking system should fail.
