fuel AUDI S6 2014 Owner's Manual

Winter operation
At temperatures below 20° F (-7° C), Diesel
fuel No.
2 loses its fluidity due to wax separa­
tion, which may clog the fuel filter or tank fil­
ter and keep the engine from running .
To help the filter from being clogged by wax,
the fuel filter in your vehicle is automatically
preheated. Preheating the fuel filter makes
operation of your vehicle possible with Diesel
fuel No . 2 down to -10° F (-24° C).
If you expect temperatures below
5° F
(-15° C)
ask your fuel dealer whether their
Diese l fuel No.
2 is sufficiently winterized for
the prevailing and expected temperatures.
If not winterized or insufficiently winterized
Diesel fuel has already thickened to the extent
that the engine will not start, warm the vehi­
cle up by leaving it in a heated garage.
It is normal that the engine noise leve l (die­
seling) is louder during the warm-up period in
winter.
It is also norma l when whitish-blue
smoke comes out of the tailpipe after start ing
and during warm-up . The amount of smoke
depends on the outs ide temperature.
Do not let your Diese l engine id le unnecessari­
ly after a cold start. Driving off slowly will
shorten the warm-up period .
A WARNING
-Never use "starting assist fluids." They
may be potent ially explosive or cause a
"run-away" engine condition. This could
result in serious engine damage and per­
sonal injury.
- Never use fuel line anti-freeze offered for
gasoline engines .
0 Note
- Your Diesel engine has been specifically
designed to operate only on Ultra Low
Sulfur Diesel fuel. Therefore, never use
home heating oil or regular gasol ine. Th e
properties of these fuels may cause seri­
ous damage to the fuel injection system
and to the engine. Using these fuels can
-
Fuel supply and filling your fuel tank 217
cause expensive engine repai rs and will
also adversely affect your New Vehicle
Limited Warranty.
- If Diesel fuel should get on any rubber
hose, it must be wiped off immediately.
Then wash the contaminated hose por­
tion with soap and warm water. Do not
allow Diesel fuel to remain on connect­
ing hoses . They may develop leaks and
cause serious damage.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap.
If the power locking system should fail, you
can still open the flap manually -for detailed
instructions see
¢ page 220.
You can find the fuel tank capacity of your ve­
hicle in
¢ page 281.
T he labe l on the inside of the fuel fi ller flap
tells you the correct fuel for your vehicle. For
more information about fuel specifications,
see
¢ page 215.
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 refue l your vehicle. In order to fi ll the tank
properly while protecting the environment,
please follow this refueling procedure careful­
ly.
A WARNING
Under normal operating conditions, never
carry addit ional fuel conta iners 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 b lower, etc., be very careful and al­
ways observe loca l and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the

(D Note
Never drive your vehicle until the fuel tank
is completely empty. The irregular supply
of fuel can cause misfiring . Gasoline could
enter the exhaust system and damage the
catalytic converter.
Refuelling
Fig. 179 R ig ht rear v ehicl e side: Openin g th e fu el fille r
fl ap
Fig. 180 Fu el f iller flap with attached f uel cap
When activating the central locking, the fuel
filler flap is automatically unlocked or locked .
Refuel the vehicle with the ign ition switched
off .
Taking the fuel cap off
,. Press the left side of the fuel filler flap to
open it
c:> fig. 179 -arrow -.
,. Unscrew fuel filler cap counter -clockwise
and hang it on the fuel filler flap
c:> fig. 180.
,. Check the label on the inside of the fuel fill­
er flap to determine if the vehicle must be
fueled with gasoline or diesel fuel.
Refuelling procedure
,. Insert the fuel nozzle from the gasoline
pump into the fuel filler neck as far as it will
go .
,. Select a med ium r efuelling rate so that the
no zzle switches off automatically when the
tank is full.
Putting the fuel cap back on
,. After filling your tank, twist the fuel filler
cap clockwise as far as it w ill go.
,. Close the fue l filler flap.
T o avoid fuel spilling or evaporating from the
fuel tank always close fuel filler cap properly
and completely. An improperly closed fuel fill­
er cap may also cause the MIL lamp
c:> page 30
to come on.
A WARNING
Improper refue ling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel 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
fuel to spray out of filler neck or to over­
flow. Fuel spray and overflowing fuel can
cause a fire.
- Never use a cellular telephone while re­
fue ling. The electromagnet ic rad iat ion
can cause sparks that can ignite fuel va­
pors and cause a fire.
- Never get back into your vehicle whi le re­
fueling.
If in exceptional circumstances
you must get back in your vehicle while
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 your veh icle when refu-
eling or filling a portable fuel conta iner . ..,

-For your safety, we strongly recommend
that you do not travel with a portable
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 examp le, in the luggage compart­
ment, or on the trunk) . Static electrici­
ty can build up while filling and can ig­ n ite fuel vapors causing a fire .
- Always place a portable fuel container
on the ground before filling.
- Always keep the fi ller nozzle comp lete­
ly inside the portable container before
and during filling.
- If filling a portable container made of
metal, the filler nozzle must always be
in contact with the container . This will
he lp prevent static electricity from dis­
charging and cause a fire .
- Never sp ill fuel inside the vehicle or
luggage compartment. Fuel vapors are highly f lammable.
- 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
F852-86).
«I) 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 fue l because fuel may spill out. In
add ition, the expans ion space in the fuel
tank will be fi lled -causing the fue l to
Fu el su ppl y and fi lling yo ur fu el t an k 219
overflow when it becomes warm and pol­
l ute the environment .
(0 Tips
-Running your eng ine while refue lling
may cause vapors to escape or even
cause fuel 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 with 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 misfueling protector. It allows the
vehicle to be fueled only with a diesel
fuel pump nozzle. A worn or damaged nozzle or a nozzle that is too small may
not be ab le to open the diesel misfueling
protector. If this is the case, try turning
the nozzle before insert ing it in the f uel
filler neck, use a different fuel pump or
see your authorized Audi dea ler 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 . •

Selective catalytic
reduction
General information
Applies to vehicles: with diesel engine
On vehicles with selective cata lytic reduction,
an urea solution (Ad B lue) is injected into the
exhaust system before a nitrogen oxide cata­
lytic converter to reduce nitrogen emissions.
The Ad Blue is stored in a separate tank in the
vehicle. The Ad Blue usage accounts for ap­
proximately 0.5% to 1.2% of the diesel fuel
that is used.
You must refill the Ad Blue or have it refilled
by you r authorized Audi dea ler or qualified
workshop as soon as the Ad Blue refill mes­
sage appears in the instrument cluster
¢page 222.
A WARNING
-Failure to heed AdBlue refill information in
the instrument cluster can prevent the ve­
hicle from be ing started and driven . If the
vehicle cannot be driven and an emergency
arises, personal injury can occur.
- Always have the AdBlue tank refilled well
before the tank runs dry.
(D Tips
-The instrument cluster display ind icates
the distance remaining that can be driv­
en

Filling AdBlue
Applies to vehicles: with diesel engine
A special refill bottle must be used to fill the
AdBlue .
Fig. 184 Rig ht rear vehicle side: remov ing the Ad B lue
cap
Fig . 185 Ad Blue filler tube: inse rting the refill bottle
The AdBlue fi ller tube is located near the die­
sel filler tube . Always add 1.5 gallons (5. 7 lit­
ers) of AdBlue (three bottles). This is the mini­
mum amount required to ensure the system
detects the refilling and to start the eng ine.
The AdBlue tank capacity is approximately
4 .5 gal lons (17 liters).
Opening the filler tube and adding
AdBlue
Requirement : The request to add Ad Blue must
appear in the instrument cluster display.
• Switch the ignition off .
• Open the tank cover
¢page 218.
• Turn the cap counterclockw ise with the lug
wrench from the vehicle tool kit to remove it
¢fig. 184.
• Remove the cap from the refill bottle.
• Position the refill bottle on the filler tube
and turn the bottle clockwise until it stops
turning
(D ¢ fig . 185.
• Press lightly against the bottom of the bot­
tle @to empty it. Continue pressing the
bottom of the bottle until it is empty or un­
til fluid stops flowing into the tank.
• Turn the bottle to the left without pressing
on the bottom .
Closing the filler tube
• Turn the cap clockwise on the filler tube
with the lug wrench until you hear it tighten
completely .
• Close the tank cover.
After filling
The vehicle must be driven. The system may
take up to two minutes to detect that the
AdBlue has been f illed.
• If there was no Ad Blue left in the tank and a
range of
O mi (0 km) was displayed in the
instrument cluster, switch the ignition on
for about 15 seconds before starting the en­ gine.
A WARNING
= Ad Blue can irritate the sk in, eyes and res-
piratory system. If there is contact with
the fluid, flush immediately with plenty of
water. Consult a physician if necessary.
(D Note
- Only use Ad Blue that conforms to the
standard ISO 22241-1. Do not mix any
additives with the AdBlue and do not d i­
lute it with water.
-A d Blue is not a diesel add itive . Do not
add it to the diesel tank. If Ad Blue is
m ixed with diesel fuel, it can lead to
damage to the engine and the AdBlue
tank system . The Limited New Vehicle
Warranty does not cover such damage.
- Ad Blue attacks surfaces such as painted
vehicle components, plastic and carpet.
Remove the fluid as quickly as possible
w ith a damp cloth and p lenty of cold wa­
ter. If the AdBlue has already crystal-
lized, use warm water and a sponge. .,..

AdBlue residue that is not removed will
crystallize and can damage the affected
surface.
- Do not store the refill bott le in the vehi­
cle.
If it leaks, the escaping Ad Blue could
damage the vehicle interior.
- Do not allow AdBlue to come into con­
tact with clothing. If there is contact
with the fluid, flush immediately with plenty of water.
(D Tips
- You can obtain refill bott les from any au­
thorized Audi dealer or other qualified
workshop.
- Follow the AdBlue manufacturer's in­
structions for usage and storage.

.,. Raise the hood slightly¢,&. .
... Press the rocker switch under the hood up­
ward
~ fig. 187. This releases the catch.
• Open the hood.
&_ 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.
- If work on the fuel system or the electri­
cal system is necessary:

-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .

248 Tire s and whee ls
- Only when all tires on the vehicle are fi l­
led to the correct pressure, the tire pres­
sure monitoring* system can work cor­ rectly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver observe the specified tire pressure values
for the tires and the correct pressures for
the funct ion of the tire pressure mon itor­
ing system*.
- Always inflate t ires to the recommended
and correct tire pressure before driving
off.
- Driv ing with under inflated ti res bend
more, letting them get too hot resu lting
in tread separation, sudden ti re fail ure
and loss of control.
- Excess ive speed and/overloading can
cause heat bui ld -up, sudden ti re fail ure
and loss of control.
- If the tire press ure is too low or too high,
the tires wi ll wear prematurely and the
vehicle will not hand le we ll.
- If the tire is not flat and you do not have
to change a wheel immediate ly, drive at
reduced speed to the nearest service sta­
t ion to check the tire pressure and add
air as required.
Driving without va lve stem caps can cause
damage to the tire va lves. To prevent this,
always make sure that factory installed
valve stem caps on all wheels are securely mounted on the valve.
@) For the sake of the environment
Underinf lated tires will a lso increase the
fuel consumption.
Tires and vehicle load limits
There are limits to the amount of load or weight that any veh icle and any t ire ca n carry.
A veh icle that is overloaded w ill not handle
well and is more difficult to stop. Over load ing
can not on ly lead to loss of veh icle contro l, but can also damage important parts of the
vehicle and can lead to sudden tire fai lure, in­
clud ing a b lowout and sudden deflation that
can cause the vehicle to crash.
Your safety and that of your passengers also depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the veh icle. These
load lim its are technically referred to as the
vehicle's
G ro ss Vehicl e We ight R ating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of fuel, o il, coolant and other fluids plus
maximum load. The max imum load includes
the number of passengers that the vehicle is
intended to car ry ("seat ing capac ity") with an
ass umed we ight of 150 lbs (68 kg) for each
passenge r at a designated seating position
and the total weight of any luggage in the ve ­
hicle . If you tow a trai ler, the weight of the
trailer hitch and the tongue weight of the
loaded tra iler must be included as part of the
vehicle load.
The
G ro ss Axle We ight R ating ("GAWR") is
the maximum load that can be applied at each of the vehicle's two axles.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating are listed on the
safety comp liance sticker label located on the
driver's side B-pillar . Your Audi has 5 seat ing
pos itions, 2 in the front and 3 in the rear for
total seating capacity of 5 . Each seating posi­
t ion has a safety belt
Q page 138, Safety
belts.
The fact that there is an upper limit to your
vehicle's Gross Vehicle Weight Rating means
that the total weight of whatever is being car­
ried in the vehicle ( includ ing the weight of a
t ra ile r hi tch and the tongue weigh t of the
loaded tra iler) is lim ited. The more passen­
gers in the vehicle or passengers who are
heavier than the standard weights assumed
mean that less weight can be carried as lug-
gage.
