212 Checking and Fill in g
- If you put any amount of incorrect fue l in
the fue l tank, do not start the engine un­
der any circumstances. Immediately con­
tact the nearest authorized Audi dealer
or authorized Audi Service Facility for as­
sistance. These fuels contain substances
that can severely damage the fuel sys­
tem and the engine if the engine is start­
ed.
- If the diesel fuel quality is poor, it may
be necessary to have the water drained
from the water sepa rator in the
f ue l fi l­
te r
more often than specified in the
maintenance schedu le . This can help re­
duce engine ma lfunctions

Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel fi ller flap.
If the power locking system should fail, you
can st ill open the flap manually- for detailed
instructions
seer:::.> page 214.
You can find the fuel tank capacity of your ve­
hicle in
Qpage 288.
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
c;,page 210.
Your veh icle fuel tank has an onboard refue l­
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 protect ing the env ironment,
p lease follow t his refueling procedure careful­
ly.
.&_ WARNING
Under norma l operating conditions, neve r
carry additiona l fuel containers in your car .
Gas can isters and other containers used to
transport fue l can be dangerous. Such con­
tainers, full or empty, may leak and cou ld
cause a f ire in a collision. If you must transpo
rt fuel to use for your lawn mower,
snow b lower, etc., be very careful and al­
ways observe local and state laws regard­ ing the use, transportation and storage of
such fuel containers. Make certa in the con­
tainer meets industry standa rds (ANSI/
ASTM F8S2 -86).
(D Note
Neve r drive your veh icle until the fue l tank
i s completely empty. The irregular supply
of fue l can cause misfir ing. Gasoline cou ld
enter the exhaust system and damage the
catalytic converter.

~ Close fuel filler door until it latches.
Once the pump nozzle switches off, the fuel
tank is "full". Do not fill the tank more. Other­
wise the expansion space in the tank will be
filled.
The correct fuel type for your vehicle can be
found on a label located on the inside of the
fuel filler door. For additional information on
fuel, refer to ¢
page 210.
The fuel tank capacity of your vehicle is in the
Technical Data ¢ page 288.
To 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 ¢

to come on .
A WARNING
Not paying attention when fueling or han­
dling fuel incorrectly can lead to fires, ex­
plosions or serious injuries.
- Fuel ignites easily and can cause serious
burns and other injuries.
- If you do not switch the engine off when
fueling and/or do not insert the fuel noz­
zle completely into the tank opening,
fuel can leak out or run over. Leaked fuel
can ignite and start a fire.
- Do not use the telephone while fueling.
The electromagnetic rays can cause
sparks, which can ignite fuel vapors and
start a fire .
- Do not sit in your vehicle while fueling. If
you must make an exception and enter
your vehicle again while fueling, close
the door and touch metal to discharge
static electricity before touching the fuel
nozzle. Static electricity can create
sparks, which can ignite vapors when fu­
eling.
Checking and Filling 213
- Do not smoke or have an open flame in
the area when fueling your vehicle or fill­
ing a fuel container because this increas­
es the risk of an explosion .
- For your safety, carrying fuel containers
in your vehicle is recommended. Wheth­
er full or empty, the container can leak
and cause a fire in the event of an acci­
dent.
- If you must make an exception and
transport a fuel container, note the fol­ lowing:
- Never fill the fuel container with fuel
while it is in or on the vehicle. Static
electricity is discharged when filling
which can cause the fuel vapors to ig­ nite and increases the risk of an explo­
sion.
- Always place a fuel container on the
ground before filling.
- Always hold the fuel nozzle completely
in the fuel container when filling .
- If the fuel container is made of metal,
the fuel nozzle must always be in con­
tact with the container when filling it
with fuel. This prevents static electrici­
ty from discharging.
- Never spill fuel in the vehicle or the
luggage compartment. Evaporated fuel
is explosive and increases the risk of
serious injury or death.
- Follow legal requirements when using,
storing and transporting fuel contain­
ers.
- Make sure the fuel container conforms
to industry standards (ANSI/ASTM
F8S2-86).
@ Note
- Remove spilled fuel from vehicle paint
immediately, because it can damage
paint.
- Never drive until the fuel tank is com­
pletely empty . The irregular supply of
fuel that results from that can cause the
engine to misfire. Uncombusted fuel will
enter the exhaust system and increase

Selective catalytic reduction
General information
Applies to vehicles: with diesel e ngine
In vehicles with se lective cata lytic reduction, a
urea solut ion (Ad Blue) is injected into the ex­
haust system before a nitrogen oxide catalytic
converter to reduce nitrogen -emissions .
Ad Blue is the marketing name for Diese l Ex­
ha ust Fluid (DEF) .
The AdBlue is carried in a separa te tank in t he
vehicle . The AdBl ue usage accounts for ap­
proximately 0.5% to 1.2% of the diese l fuel
that is used .
When a message abo ut refil ling the Ad Blue
appears in the inst rume nt cl uste r dis play, you
must refi ll the Ad B lue yourse lf or have it refil­
l ed by an authorized Audi dealer or aut horized
Aud i Service Facility
Q page 216.
A WARNING
Failure to heed Ad Blue refill information in
the inst rume nt cluste r can p revent the
ve­
hicle from being started and driven . If the
veh icle cannot be driven and an eme rgency
ar ises, perso na l inju ry can occur.
- Always have the Ad Blue tank refilled well
before the tank r uns d ry.
(!) Tips
- The instrument cluster display indicates
the d istance remaining that ca n be dr iv ­
en

_& WARNING
Ad Blue can irritate the skin, eyes and res­piratory 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 Ad Blue and do not di­lute it with water .
- Do not add Ad Blue to the diesel tank or
add diesel fuel to the Ad Blue tank. Mix­
ing can lead to damage to the engine
and the Ad Blue tank system. Warranty
does not cover damage caused by this.
- AdBlue attacks surfaces such as painted
vehicle components, plastic and carpet.
Remove the fluid as quickly as possible
with a damp cloth and plenty of cold wa­
ter. If the Ad Blue 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 bottle 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.
@ Tips
- You can obtain refill bottles from an au­
thorized Audi dealer or authorized Audi
Service Facility.
- Follow the AdBlue manufacturer's in­
structions for use and storage.
