2015 AUDI S6 fuel cap release

30 Instruments and warning /indicator lights
has been assigned a code. In case of a ma l­
function, the component will be identified
and the fault stored as a code in the contro l
module memory.
The MIL light may a lso illuminate if there is a
leak in the on-board fue l vapor recovery sys­
tem .
If the light illuminates after a refue lling,
stop the vehicle and make sure the fuel filler
cap is properly closed ¢
page 216.
In order to make an accurate diagnosis, the
stored data can only be displayed using spe­
cial diagnostic equipment (generic scan tool
for OBD) .
In order to connect the special diagnostic
equipment, push the plug into the Data L ink
Connector (DLC). The DLC is located to the
right of the hood release¢
fig. 16.
Your authorized Audi dealer or a qualified
service station can interpret the code and per­
form the necessary repair .
A WARNING
Do not use the diagnostic connector for
personal use . Incorrect usage can cause
malfunctions, which can increase the risk
of a coll ision!
Electronic speed limiter
-
Your veh icle may be factory equipped with
tires that are rated for a maximum speed of
130 mph (210 km/h). This is less than the
maximum speed of you r vehicle. To reduce the
risk of sudden tire failure and loss of control if
the vehicle is operated at excessive speeds,
your veh icle also has an electronic speed limit­
er. The electronic speed limiter prevents your
vehicle from go ing faster than the tire speed
rating. For more informat ion ¢
page 257 .
If the engine control unit receives faulty vehi­
cle road speed s ignals, the Malfunction Indi­
cator Lamp (MIU
¢'4 will illuminate. If this
occurs, contact the nearest authorized Aud i
dealer for assistance. S models
Your
vehicle's top speed is elect ron icall y limit­
ed to 155 mph (250 km/h).
If the engine control unit receives faulty veh i­
cle roadspeed signals, the Malfunction Indica­
tor Lam p (MIL)
¢'4 will illuminate . If this oc­
curs, contact the nearest authorized Audi
dealer for assistance.

Refuelling procedure
"'Insert the fuel nozz le from the gasoline
pump into the fue l filler neck as far as it will
go.
"' Se lect a medium refuelling rate so that the
noz zle switches off automatically when the
tank is full.
Putting the fuel cap back on
"'After filling your tank, twist the fuel fi ller
cap clockwise as far as it will go.
"' Close the fuel filler flap .
To avoid fuel spi lling or evaporating from the
fuel tank always close fuel fi ller cap properly
and comp letely. An improperly closed fuel fill­
er cap may also cause the MIL lamp¢
page 29
to come on.
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns .
- Fuel is highly flammable and can cause
severe burns and other injuries .
- Failure to shut the eng ine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel f iller neck could cause
fuel to spray out of filler neck or to over­
flow. Fuel spray and ove rflow ing fuel can
cause a fire.
- Never use a cellular telephone while re­
fueling. The elect romagnetic radiation
can cause sparks that can ignite fue l va­
pors and cause a fire.
- Never get back into you r vehicle while re­
fueling. If in exceptiona l circumstances
yo u must get back in your vehicle wh ile
refueling, make certain that you close
the door and touch metal to discharge
static electricity before touching the fill­
er nozzle again. Static electricity can
cause sparks that can ignite fuel vapors
released during refueling.
- Never smoke or have an open flame any­
where in or near you r vehicle when refu­
eling or filling a portable fuel container .
- For your safety, we strongly recommend
that you do not travel w ith a portable
Fuel supply and filling your fuel tank 217
fuel container in your vehicle. The con­
tainer, full or empty may leak and could
cause a fire, especially in a crash.
- If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portable fuel container
while it is anywhere in or on the vehicle
(for example, in the luggage compart­
ment, or on the trunk) . Static electrici­
ty can build up while filling and can ig­
nite fuel vapors causing a fire.
- Always place a portab le fue l conta iner
on the ground before fi lling.
- Always keep the filler nozzle complete­
l y inside the portable container before
and during filling.
- If filling a portab le container made of
metal, the fi ller nozzle must always be
i n contact with the conta iner. This will
help prevent static electric ity from dis­
charging and cause a fire .
- Never spill fuel inside the vehicle or
luggage compartment. Fuel vapors are
highly flammable .
- Always observe local and state/provin­
cial laws regarding the use, storage
and transportation of fuel containers .
- Make certain the fuel container meets
industry standards (ANSI/ ASTM
F8S2 -86) .
(D Note
If any fuel has spilled onto the car, it
should be removed immediately to prevent
damage to the paint .
@) For the sake of the environment
As soon as the correctly operated nozzle
switches off automatically for the first
time, 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 pol­
l ute the environment . •

218 Fuel supply and filling your fuel tank
@ Tips
-Running your engine while refuelling
may cause vapors to escape or even
cause fue l to spill out of the tank. This
would then shut off the fuel nozzle be­
fore the tank is full.
- Do not refuel your vehicle w ith the igni­
tion switched on. The fuel gauge may
otherwise not indicate the correct fuel
level after refuelling.
- Diesel vehicles* are equipped with a die­
sel m isfueling protector. It allows the
vehicle to be fueled only w ith a diesel
fuel pump nozzle. A worn or damaged
nozzle or a nozzle that is too small may
not be able to open the diesel misfueling
protector . If this is the case, try turning
the nozz le before inserting it in the fue l
filler neck, use a different fuel pump or see your authorized Audi dealer or au­
thorized repair facility for assistance.
- The fuel filler flap of your vehicle is not
locked when you lock the vehicle from
the inside.
Fuel filler flap emergency release
You can open the fuel filler flap by hand if the
power locking system should fail.

A WARNING
Hot engine coolant can burn you.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment . Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood .
' Working in the engine compartment
Be especially careful whenever you work in
the engine compartment.
Whenever you must perform any work in the
engine compartment, for example checking
and filling different fluids, there is a risk of injury, burns and accidents. To prevent per­
sonal injury always observe the following
WARNINGS. The engine compartment of any
vehicle is a hazardous area
¢ ,&. .
A WARNING
To help avoid injury, before you check any­
thing under the hood:
- Turn off the engine.
- Switch off the ignition .
- Apply the parking brake.
- Move selector lever to P (Park).
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment. Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood.
- Keep children away from the engine com­
partment.
- Never spill fluids on hot engine compo­
nents . They can cause a fire .
- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly .
- Never open the coolant reservoir cap
when the engine is still warm . The cool­
ant system is pressurized and hot cool­
ant could spray out.
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir.
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
