Diesel can thicken at very low temperatures,
which can result in problems starting the engine
or prevent the engine from running smoothly. For
this reason, filling stations in some countries of­
fer winter-grade diesel fuel during the cold
months so that you can continue to operate your
vehicle reliably. Ask at your filling station wheth­
er the diesel fuel available there is suitable for
the current conditions and for the temperatures
which could potentially occur.
CD CAUTION
- Never use FAME fuels (biodiesel), petrol,
heating oil, thinners or any other fuels or
additives, as these could cause serious dam­
age to the fuel system and the engine.
- Never start the engine if you fill up with the
wrong type of fuel, as this could damage
the fuel system and the engine. Obtain pro­
fessional assistance.

ca �
Press the tank flap -arrow- ¢ Fig. 204 to open
it. Your vehicle has a new self-sealing fuel tank
without a tank cap.
� Insert the filler nozzle into the fuel filler neck
as far as the stop ¢ Fig. 205 and ensure it is
properly engaged.
� Start refuelling. When the automatic filler noz­
zle is operated correctly it will switch itself off
as soon as the tank is "full". Do not try to put in
more fuel after the nozzle cuts out, as this will
fill the expansion chamber in the fuel tank.
� 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.
� Close the tank flap. Make sure you hear it click
into place.
The correct fuel grade for your vehicle is given on
a sticker on the inside of the tank flap. Further
notes on fuel ¢page 217.
The tank capacity of your vehicle is given in the
Technical data section ¢ page 258.
& WARNING
Fuel is highly inflammable and can cause seri­
ous burns and other injuries.
- For safety reasons we do not recommend
carrying a spare fuel canister in the vehicle.
The canister could become damaged in an
accident and leak.
- Observe all relevant statutory regulations
on using, storing and transporting spare
fuel canisters.
- When filling your tank or a spare fuel canis­
ter with fuel, do not smoke and keep away
from naked flames -risk of explosion!
- If,
in exceptional circumstances, you have to
carry a spare fuel canister, please observe
the following warnings:
- Never fill fuel into the spare fuel canister
with the canister placed in or on top of the
vehicle. An electrostatic charge could
build up during filling, causing the fuel va­
pour to ignite -risk of explosion! Always
place the canister on the ground to fill it.
- Insert the filler nozzle as far as possible
into the spare fuel canister.

.... -
If the spare fuel canister is made of metal,
the filler nozzle must be in contact with
the canister during filling. This helps pre­
vent an electrostatic charge building up.
- Make sure you never spill fuel in the vehi­
cle or in the Luggage compartment. Fuel
vapour is explosive -danger to Life!
CD CAUTION
- Remove any fuel spills from the paintwork
immediately.
- 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
cata Lytic converter(s).
- When filling the fuel tank after having run it
completely dry on a vehicle with a diesel en­
gine 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.
(® For the sake of the environment
Do not overfill the fuel tank -this may cause
the fuel to overflow if it becomes warm.
(1j) Note
Should the fuel tank flap become frozen stuck
during inclement weather, press the middle
of the flap with the palm of the hand and try
again.
@ Note
To prevent the tank from being filled with the
incorrect type of fuel (petrol or diesel), only
suitable filler nozzles can be inserted in the
fuel filler on your vehicle.
- If the filler nozzle is old, damaged or too
small, it may not be able to open the pro­
tection mechanism on the fuel tank. In this
case, try turning the filler nozzle before in­
serting it in the fuel filler neck, use a differ- Checking

ent filling pump or seek professional assis­
tance.
- The protection mechanism will not open if
you try to add fuel from a spare fuel canis­
ter. If you need to fill the tank from a spare
fuel canister, you must use the special fun­
nel stowed in the Luggage compartment
¢page 219, Fig. 206.

systems
Catalytic converter
Applies to vehicles with petrol engine: The vehi­
cle must only be used with unleaded petrol; oth­
erwise the catalytic converter will be irreparably
damaged.
Never allow the fuel tank to run completely dry,
as the irregular supply of fuel can cause misfir­
ing. This allows unburnt fuel to enter the exhaust
system, which can cause overheating and dam­
age to the catalytic converter.
Diesel particulate filter
Applies to vehicles with diesel engine: The die­
sel particulate filter can filter out almost all soot
particles contained in the exhaust gas. In normal
driving conditions the filter is self-cleaning.
Should the self-cleaning function of the filter not
be able to operate, e.g. when the vehicle is con­
tinuously used only for short trips, the filter be-
220 comes
obstructed with soot and the symbol Cl
for the diesel particulate filter lights up
¢page 15.
A WARNING
The exhaust system is very hot when the vehi­
cle is being driven and after the engine has
been switched off.
- Never touch the tailpipes when they are hot
- risk of burns!
- Because of the high temperatures which can
occur in the emission control system (cata­
lytic converter or diesel particulate filter),
do not park the vehicle where the exhaust
can come into contact with flammable ma­
terials under the car (e.g. on grass or at the
forest edge) -risk of fire!
- Do not apply any undersea[ agents in the
area around the exhaust system -risk of
fire!
Engine compartment
Working on components in the engine

pected. This applies particularly if you drive
into a colder climate zone.
- To prevent damage to the engine, do not
use a different type of anti-freeze additive if
the approved type of additive is not availa­
ble. In this case use only water and bring
the coolant concentration back up to the
correct level as soon as possible by putting
in the specified additive.
- Always top up with fresh, unused coolant.
- Radiator sealants must not be added to the
coolant.
Topping up coolant
Fig. 214 Engine compartment: Cap of coolant expansion

Checking coolant level
.. Park
your vehicle on a level surface .
.. Switch off the ignition .
.. Read off the coolant level on the coolant expan­
sion tank ¢ page 222, Fig. 211. When the en­
gine is cold, the coolant level should be be­
tween the marks. When the engine is warm, it
may be slightly above the top mark. Checking
and topping up fluids
Topping up coolant
Impor tant: The coolant expansion tank must not
be empty ¢(D.
.. Wait for the engine to cool down.
.. Cover the cap on the expansion tank with a
cloth, and carefully unscrew the cap anti-clock­
wise ¢ .&_ .
.. Add coolant in the correct concentration
¢ page 224 up to the top mark.
.. You should make sure that the fluid level re-
mains stable. If necessary, add more coolant.
.. Screw the cap on again tightly.
Any loss of coolant normally indicates a leak in
the cooling system. Drive to a qualified workshop
without delay and have the cooling system
checked. If there are no leaks in the system, a
loss of coolant can only occur if the coolant boils
and is forced out of the system as a result of
overheating.
A WARNING
- The cooling system is under pressure. Do
not unscrew the cap on the expansion tank
when the engine is hot: you could be scal­
ded by escaping steam.
- The coolant and coolant additive can be a
health hazard. Store the coolant additive in
the original container in a safe place out of
reach of children -risk of poisoning.
- When working in the engine compartment
be aware that the radiator fan may start
running suddenly, even if the ignition is
switched off-risk of injury!
CD CAUTION
Do not add coolant if the expansion tank is
empty. Air could have got into the cooling sys­
tem -risk of engine damage! In this case, do
NOT drive on. Obtain professional assistance .

Changing brake fluid
Your vehicle's Service Schedule will tell you the
regular intervals at which the brake fluid is due
for renewal. We recommend that you have the
brake fluid changed by a qualified workshop dur­
ing a service.
A WARNING
- Brake fluid is poisonous; it must be stored in
the sealed original container in a safe place
out of the reach of children.
- Heavy use of the brakes may cause a vapour

will attack the paintwork.
Battery General notes
ALL work on batteries requires specialist knowl­
edge.
The battery is virtually maintenance-free. It is
checked as part of the Inspection Service.
When an airbag is triggered, the battery will, un­
der certain circumstances, be disconnected from
the on-board power supply for safety reasons
¢ .&.. in General notes on airbag system on
page 209.
Disconnecting the battery
The battery should always be Left connected. If
the battery is disconnected, some of the vehicle's
functions will become inoperative (e.g. electric
windows). These functions will require resetting
after the battery is reconnected. For this reason,
the battery should only be disconnected from the
vehicle's electrical system when absolutely nec­
essary.
If the vehi cle is not used for long periods
If you do not drive your vehicle for a period of
several days or weeks, the power management
will gradually shut off the on-board systems one
by one, or reduce the amount of current they are
using. This Limits the amount of power consumed
and helps to ensure reliable starting even after a
Long period ¢ page 106. Certain convenience fea­
tures, such as interior Lighting or electric seat ad­
justment, may not be available. These functions
will be restored when you switch on the ignition
and start the engine. Even though some systems
are deactivated automatically, certain electrical
equipment continues to draw current even when
the ignition is off. If the vehicle is Left standing
for several months, this can result in total bat-
tery discharge. If the battery is allowed to dis­
charge completely, an internal chemical reaction

and tyres
Wheels General notes
... Inspect the tyres regularly for damage (cuts,
cracks or blisters, etc.). Remove any foreign
bodies embedded in the treads.
... If you have to drive over a kerb or similar obsta­
cle, drive very slowly and as near as possible at
a right angle to the kerb.
... Damaged rims or tyres must be replaced imme­
diately.
... Keep grease, oil and fuel off the tyres.
... Mark
the wheels before taking them off so that
they rotate in the same direction when refitted.
... When removed, the wheels should be stored
flat in a cool, dry and preferably dark place.
CD CAUTION
- Please note that summer and winter tyres
are optimised for the prevailing road condi­
tions at different times of year. We recom­
mend that you use winter tyres during the
winter months. At low temperatures, sum­
mer tyres lose their elasticity and grip, and
braking performance also suffers as a re­
sult. Cracks can form in the tread block on
summer tyres if they are used at very cold
temperatures, and this can cause perma­
nent damage to the tyres. An increase in
rolling noise and tyre imbalance may result
from this damage.
- Machined, polished or chrome-plated rims
must not be used in winter conditions. The
process used to manufacture these types of
wheel rim does not provide adequate sur­
face protection against corrosion, and the
rims can be permanently damaged by road
salt or similar.
New wheels or tyres
It is best to have all servicing of wheels and tyres
performed by a qualified workshop, since they
have the necessary special tools and replacement
parts and trained personnel. Wheels
and tyres
... New tyres do not yet give maximum grip. When
driving with new tyres, drive at moderate
speeds and be especially careful during the first
500 km.
... All four wheels must be fitted with tyres of the
same type, size (rolling circumference) and
preferably the same tread pattern.
... Tyres should be replaced in pairs and not indi­
vidually (i.e. both front tyres or both rear tyres
together).
... We recommend the use of Audi Genuine Tyres.
If you wish to use other tyres, please note that
the actual size can differ from the nominal size
marked on the tyre ¢.&_
.
... If you wish to purchase a different combination
of rims and tyres than the ones fitted on the ve­
hicle during production, it is advisable to con­
sult a qualified workshop beforehand ¢.&_
.
On vehicles with four-wheel drive, all four wheels
must always be fitted with tyres of the same
type, make and tread pattern, as otherwise the
driveline can be damaged by variations in the
wheel speeds. For the same reason, only use a
spare wheel* which has the same rolling circum­
ference as the normal road wheels.
If the spare wheel* is not the same type as the
tyres fitted on the car (for example if the car has
winter tyres or wide-section tyres) you should on­
ly use the spare wheel* if a puncture occurs, and
then only for a short period of time. In this case,
please drive with extra care. Refit a normal road
wheel as soon as possible.
Manufacturing date
The manufacturing date is indicated on the tyre
sidewall (possibly only on the inner side of the
wheel):

means, for example, that the tyre was produced
in the 22nd week of 2014.
Audi Genuine Tyres
Audi Genuine Tyres with the marking "AO" or
"RO" are specially matched to your Audi. When
used properly, these tyres meet the highest
standards in safety and handling. Your specialist
