and cooling
To prevent the front side windows from misting
up in wet weather, it's a good idea to open the
side air outlets and point them to the side.
� Switching air recirculation on/off
The air recirculation mode can be switched on
manually or automatically*.
- To switch the manual air recirculation mode on/
off, press the G;J button.
- The automatic* air recirculation function must
be activated on the infotainment system. Se­
lect the following on the infotainment system:
I MENU I
button > Car > Left control button > Ve­
hicle settings > A/C > Auto recirculation. The
air quality sensor, which is designed for the de­
tec tion of diesel and petrol exhaust fumes, au­
tomatically switches the air recirculation mode
on or off depending on the Level of pollution in
the outside air.
In air recirculation mode, the air from the interior
of the vehicle is filtered and recirculated. This
setting prevents fumes etc. from entering the in­
terior. We recommend switching on the air recir­
culation mode when driving through a tunnel or
in traffic
queues ¢ A.
The air recirculation mode is switched off when
the G;J or I AUTO
I or I
� M
AX
I button is pressed.
Iii) MAXI Switching
the defroster on/off
The windscreen and side windows are defrosted
or demisted as quickly as possible. Most of the
air comes out of the outlets below the wind­
screen. The air recirculation mode is deactivated.
The temperature is regulated automatically.
The defroster is switched off when the !AUTO!
button is pressed.

Switching the rear window heating
on/off
If rear window heating is activated with the igni­
tion switched on, the battery management deter­
mines whether or not the battery charge Level is
sufficient for the rear window heating to be
switched on. Otherwise the rear window heating
operates when the engine is running, and
switches off automatically after about
56 10
-20 minutes, depending on the outside tem­
perature.
To switch on the rear window heating permanent­
ly, press and hold the Imo RE A
R! button for at Least
two seconds. This setting will be stored for ap­
proximately 15 minutes after the ignition is
switched off.
A WARNING
For reasons of safety you should not Leave the
air recirculation switched on for too Long. This
mode prevents fresh air from entering the ve­
hicle, so the windows can mist over if the air
cooling is switched off. Bad visibility can cause
an accident.

Never spill fluids on a hot engine. These flu­
ids can cause a fire (e.g. radiator anti­
freeze).
- Take care not to cause short circuits in the
electrical system, especially when working
on the battery.
- 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!
- Do not unscrew the cap on the expansion
tank when the engine is hot. The cooling
system is under pressure.
- Protect face, hands and arms by covering
the cap with a large, thick rag to protect
against escaping coolant and steam.
- Never remove the engine cover panel -risk
of burns!
- If any tests have to be performed with the
engine running, there is an extra safety risk
from the rotating parts, such as the drive
belts, alternator and radiator fan, etc., and
from the high-voltage ignition system.
- Vehicles with automatic gearbox: Never
open the throttle inadvertently (for instance
by hand from the engine compartment) if a
gear is engaged while the vehicle is station­
ary with the engine running. The vehicle
could otherwise start moving immediately
and possibly cause an accident.
- Observe the following additional warnings if
work on the fuel system or the electrical
system is necessary:
- Always disconnect the battery.
- Do not smoke.
- Never work near naked flames.
- Always keep an approved fire extinguisher
immediately available.
CD CAUTION
When topping up fluids make sure the correct
fluid is put into the correct filler opening. This
can otherwise cause serious malfunctions or
engine damage. Checking
and topping up fluids
® For the sake of the environment
Inspect the ground underneath your vehicle
regularly so that any leaks are detected at an
early stage. If you find spots of oil or other
fluids, have your vehicle inspected in the
workshop.

Depending on how you drive and the conditions
in which the car is used, oil consumption can be
up to 0.5 Ltr./1000 km. Oil consumption is Likely
to be higher for the first 5000 km. For this rea­
son the engine oil Level must be checked at regu­
lar intervals, preferably when filling the tank and
before a journey.

dipstick all the way in.
_& WARNING
- Ensure that no oil comes into contact with
hot engine components when topping up:
this could cause a fire.
- Wash your skin thoroughly if it comes into
contact with engine oil.
CD CAUTION
- The oil Level must never be above area 0, as
this may result in damage to the catalytic
converter or to the engine. Contact a qua Li-
224 fied
workshop to extract the engine oil if
necessary
- No additives should be used with engine oil.
Any damage caused by the use of such addi­
tives would not be covered by the factory
warranty.
@ For the sake of the environment
- Never pour oil down drains or into the
ground.
- Always observe statutory requirements
when disposing of empty oil canisters.
Cooling system
Coolant
The engine cooling system is filled at the factory
with a mixture of conditioned water and coolant
additive. This coolant must not be changed.
The coolant Level is monitored via a warning Lamp
on the infotainment display ¢page 12. However,
we re com mend that it shou Ld be checked occa­
sionally.
If you do need to top up the coolant, use a mix­
ture of water and coolant additive. We recom­
mend mixing coolant additive with distilled wa­
ter .
Coolant additive
The coolant additive contains anti-freeze and cor­
rosion protection agent. Only use one of the fol­
lowing coolant additives. It is possible to mix
these additives.
Coolant additive Specification

ble: G12+
The amount of coolant additive which needs to
be mixed with the water depends on the temper­
atures to be expected in the winter season. If the
anti-freeze concentration is too Low, the coolant
can freeze and cause engine damage.

CD CAUTION
- Have your qualified workshop check the
cooling system before the winter season to
make sure that the anti-freeze concentra­
tion is adequate for the conditions to be ex­
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.

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 .

Downloaded from www.Manualslib.com manuals search engine Wheels
and tyres
& WARNING
- Use only tyre/rim combinations and match­
ing wheel bolts approved by Audi. Otherwise
damage to the vehicle and an accident could
result.
- For technical reasons, it is not possible to
use wheels from other vehicles. In certain
cases, it is not even possible to use wheels
from another vehicle of the same model.
- It is very important to ensure that the tyres
you have chosen have adequate clearance.
When selecting replacement tyres, do not
rely entirely on the nominal tyre size marked
on the tyre; with some makes of tyre the ef­
fective tyre size can differ significantly from
the nominal dimensions, even though the
tyres have the same size designation. Inade­
quate tyre clearance can result in damage to
the tyres or the vehicle, causing a serious
safety risk.
- Avoid running the car on tyres that are more
than 6 years old. If you have no alternative,
you should drive slowly and with extra care
at all times.
- The use of run-flat tyres on your vehicle is
NOT authorised! Unauthorised use can cause
an accident or damage your vehicle.
- If wheel trims are fitted after the car is pur­
chased, ensure that there is an adequate
flow of air for cooling the brakes -risk of ac­
cident!
Tyre wear / damage
Fig. 219 Tyre tread: Tread wear indicators
l l
Please observe the applicable regulations in the country in
which you are travelling.
232 Tyre
wear
Inspect the tyres regularly for damage.
- The wear on under or over-inflated tyres is sig­
nificantly higher.
- Fast cornering, heavy acceleration and hard
braking all increase tyre wear.
- If you notice excessive tyre wear, have the
wheel alignment checked by a qualified work­
shop.
- Have your tyres rebalanced if steering wheel vi­
brations indicate an imbalance. Otherwise, the
tyres and other parts of the vehicle may wear
faster.
Tread wear indicators
The original tyres on your vehicle have 1.6 mm
high tread wear indicators ¢ Fig. 219 running
across the tread at regular intervals. The letters
"TWI" or triangles on the sidewall indicate the
positions of the tread wear indicators.
The minimum tread depth 1
) is reached at the lat­
est when the tread is worn down to the tread
wear indicators. Replace the tyres with new ones
¢ ,&..
Changing wheels round
Wheels should be changed round regularly to en­
sure that the wear is equal on all tyres. Fit the
wheels from the rear axle on the front axle and
vice-versa. All the tyres will then last for about
the same time.
On tyres with a directional tread pattern, note
the direction of rotation indicated on the sidewall
¢page 247.
Concealed damage
Damage to tyres and rims is often not readily visi­
ble. If you notice unusual vibrations or the car
pulling to one side, this may indicate that one of
the tyres is damaged. Reduce your speed imme­
diately. Inspect the tyres for damage. If no exter­
nal damage is visible, drive slowly and carefully
to the nearest qualified workshop and have the
car inspected.
