Driver messages

If the indicator lamp  lights up and a corre-

sponding message appears, you should add fuel

to the vehicle’s tank.

The fuel tank flap is unlocked/locked automati-

cally by the central locking system. The fuel tank

flap is not locked when you lock the vehicle from

the inside by pressing the central locking switch.

 Tank system malfunction! Please contact

workshop

There is a malfunction in the tank system. Drive

to a qualified workshop without delay and have

the fault rectified.

Preparing to fill the fuel tank

►

Switch the drive system off.

Vehicle refuelled. Reset km/miles now?

►

Press the left side of the flap to open it

ðFig. 120.

Select Yes if you want to reset the trip recorder

to zero.

Putting fuel in the fuel tank

The display of this message depends on the

amount of fuel in the tank and the amount of

fuel added.

►

Unscrew the tank cap anti-clockwise.

Hook the cap onto the open flap ðFig. 121.

Insert the filler nozzle into the fuel filler neck

►

as far as the stop.

►

Filling the fuel tank

Start refuelling. The filler nozzle cuts out as

soon as the fuel tank is full ð

►

When the fuel filler pump switches itself off,

wait for 5 seconds before pulling out the filler

nozzle so that any remaining fuel can flow into

the tank opening.

►

Screw on the tank cap clockwise until it clicks

audibly.

Press the left side of the flap to close it (you

should hear it click into place).

The correct fuel grade for your vehicle is given on

a sticker on the inside of the fuel tank flap. Fur-

ther notes on fuel ðpage 225.

The tank capacity of your vehicle is given in the

Technical data section ðpage 288. The maxi-

mum possible amount of fuel that can be added

depends on the amount remaining in the tank.

Checking and topping up fluids

To prevent fuel and vapours from escaping, make

sure that the fuel tank is properly sealed; other-

¹⁾

– The filler nozzle cuts out as soon as the fuel

tank is full. Do not try to put in more fuel af-

ter the nozzle cuts out, as this will fill the

expansion chamber in the fuel tank. Do not

try to put in more fuel after the automatic

filler nozzle has switched off; this may cause

the fuel to overflow if it becomes warm, po-

tentially at a later point in time. This can

cause explosion, fire and serious or fatal in-

juries.

wise the indicator lamp

will light up.

Information on vehicles with diesel engine

– Diesel vehicles are equipped with an incorrect

fuelling protection system . This system en-

sures that the tank can only be fuelled from a

diesel filler nozzle.

– If the filler nozzle is old, damaged or too small,

it may not be able to open the protection mech-

anism on the fuel tank. In this case, try turning

the filler nozzle before inserting it in the fuel

filler neck, use a different filling pump or seek

professional assistance.

WARNING

Audi recommends you NOT to carry a spare

fuel canister in the vehicle. Fuel could escape

from the canister and catch fire, particularly

in the event of an accident. Fire, explosions

and injuries could result.

– The protection mechanism will not open if you

try to add fuel from a spare fuel canister. You

can get round this simply by adding the diesel

slowly.

– If, in exceptional circumstances, you have to

carry a spare fuel canister, please observe

the following warnings:

WARNING

– Always place the spare fuel canister on the

ground before filling it. Never fill fuel into

the spare fuel canister with the canister

placed in or on top of the vehicle. Electro-

static electricity can build up while filling

the canister and ignite the fuel vapours.

– When using metal fuel canisters, always

keep the filler nozzle in contact with the

canister to prevent the build-up of static

electricity.

Improper refuelling and improper handling of

fuel can cause explosions, fire, serious burns

and other injuries.

– Do not smoke. Keep naked flames away

from the vehicle.

– The ignition must be switched off when re-

fuelling.

– Mobile phones and radio equipment must

always be switched off when refuelling.

Electromagnetic radiation can cause sparks

which could start a fire.

– Keep the filler nozzle inserted as far as

possible into the filler opening while fill-

ing the canister.

– The auxiliary heating must be switched off

when refuelling.

– Observe all relevant local regulations on

using, storing and transporting spare fuel

canisters.

– Fuel can escape if you do not insert the filler

nozzle all the way into the filler neck. Escap-

ing fuel can ignite and cause a fire.

– Never get into the vehicle while refuelling. If

you do have to get into the vehicle in excep-

tional circumstances, close the door and

touch a metal surface before handling the

filler nozzle again. This will discharge any

static electricity which could generate

sparks. Sparks can start a fire when refuel-

ling.

CAUTION

– If fuel overflows onto the vehicle, remove it

completely straight away to prevent dam-

age to the vehicle.

– Never run the tank completely dry. If there

is an irregular fuel supply, misfiring can oc-

cur. As a result unburnt fuel can enter the

exhaust system and cause damage to the

catalytic converter(s).

It is not sufficient to simply have AdBlue refilled

when the vehicle is serviced because this may be

necessary more often than services are due or be-

tween service intervals.

– Vehicles with diesel engine: When filling

the fuel tank after having run it completely

dry, the ignition must be switched on for at

least 30 seconds without starting the en-

gine. When you then start the engine it may

take longer than normal (up to one minute)

for the engine to start firing. This is because

air needs to be bled from the fuel system

while starting.

As soon as a message appears in the instrument

cluster display reminding you to refill AdBlue,

you must refill the AdBlue tank or have this done

by a qualified workshop ðpage 230.

Checking range

The AdBlue consumption depends on the ambi-

ent and operating temperature and on how the

vehicle is driven. The estimated remaining range

can be viewed in the instrument cluster display

For the sake of the environment

– Do not try to put in more fuel after the au-

tomatic filler nozzle has switched off; this

may cause the fuel to overflow if it becomes

warm.

ðpage 17, Instrument cluster controls and

ðpage 17, Fig. 3.

Legal information

– Never pour fuel down drains or into the

ground.

– It is not permitted to make technical changes

to the emission control system which have an

effect on the exhaust gas treatment using

AdBlue.

Having the fuel tank flap released

manually

– Audi has approved this vehicle for use only with

AdBlue corresponding to ISO-22241-1, for

which the Certificate of Conformity for this type

of vehicle has been issued.

►

If you cannot open the fuel tank flap, seek pro-

fessional assistance.

Then drive to a qualified workshop and have the

fault rectified.

►

– It may be a crime to operate the vehicle without

the AdBlue which corresponds to ISO-22241-1.

– If the emission control system is not operated

as intended, the exhaust emissions may wor-

sen.

Selective catalytic

reduction (AdBlue/DEF)

Introduction

– The use of AdBlue for the operation of this vehi-

cle is required by law.

On vehicles with selective catalytic reduction, a

urea solution (AdBlue/DEF) is injected into the

exhaust system upstream of a NOx catalytic con-

verter in order to reduce nitrogen oxide emis-

sions. The catalytic converter changes nitrogen

oxides into nitrogen and water with the help of

the urea solution AdBlue/DEF. The urea solution

is known as AdBlue or DEF (Diesel Exhaust Fluid).

The term AdBlue is used below.

Information on AdBlue

– The instrument cluster display will tell you how

far you can drive before the tank runs dry

ðpage 230, Low AdBlue level. If the AdBlue

tank runs dry, the engine cannot be started

again after you switch off the ignition. Never

run the AdBlue tank completely dry.

– Please follow the AdBlue manufacturer's in-

structions for storage and use.

The AdBlue is held in a separate tank in the vehi-

cle. AdBlue consumption is normally between

1.0 ltr. – 2.5 ltr./1000 km. In individual cases,

the consumption may be different as a result of

how the vehicle is driven along with the operat-

ing and ambient temperature.

– Restrictions may be encountered when refilling

in very cold temperatures, because the freezing

point of AdBlue is -11 °C.
