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.
Topping up coolant
Fig. 214 Engine compartment: Cap of coolant expansion
tank
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 .

Fig. 215 Engine compartment: Cap of brake fluid reservoir
Checking brake fluid level
The brake fluid Level must be between the MIN
and MAX marks on the reservoir ¢ page 222,
Fig. 211.
If the Level goes down noticeably in a short time,
or drops below the MIN mark, there may be a
Leak in the brake system. Obtain professional as­
sistance. The brake fluid Level is also monitored
via a warning Lamp on the infotainment display
¢page 11.
In right-hand drive vehicles the brake fluid reser­
voir is on the other side of the engine compart­
ment.
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
Lock if the brake fluid is left in the system
for too Long. This would seriously affect the
efficiency of the brakes and the safety of the
car -risk of accident!
226 CD
CAUTION
Brake fluid must not be allowed to come into
contact with the vehicle's body, otherwise it
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

.... Wheels
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):
DOT ... 2214 ...
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
retailer will be glad to provide more information . ..,..

- If the tyre is too badly damaged, you should
seek professional assistance.
(f!j} For the sake of the environment
A used can of sealing compound can be re­
turned to your qualified workshop for dispos­
al.
ij) Note
After repairing a tyre, remember to buy a new
tyre sealant can at a qualified workshop.

CD CAUTION
When removing/fitting the wheel the rim may
hit and damage the brake disc. For this rea­
son, please take care and get a second person
to assist you.
Tyres with directional tread pattern
A directional tread pattern can be identified by
arrows on the sidewall that point in the direction
of rotation. Always note the direction of rotation
indicated when mounting the wheel. This is im­
portant so that these tyres can give maximum
grip and avoid excessive noise, tread wear and
aquaplaning.
If you ever have a puncture and need to fit the
spare wheel* in the wrong direction, please drive
with extra care because the tyre will not give op­
timum performance in this situation. Bear this in
mind particularly when driving on wet roads.
To benefit from the advantages of tyres with this
type of tread pattern, the defective tyre should
be replaced and refitted as soon as possible so
that all tyres again rotate in the correct direction.
After changing a wheel
.,. Fit the hubcap or wheel bolt caps back on, as
required.
.,. Put the tools and jack back in the luggage com­
partment.
.,. If the replaced wheel will not fit into the spare
wheel well, stow it safely in the luggage com­
partment ¢ page 201.
.,. Check
the tyre pressure of the fitted wheel as
soon as possible.
.,. Adjust the tyre pressures and store them via
the infotainment system.
.,. The wheel bolts should be tightened to 120
Nm. Have this checked as soon as possible with
a torque wrench. Until then, drive with caution.
.,. Have
the flat tyre replaced as quickly as possi­
ble. Mobility

- Keep sparks, flame and lighted cigarettes
away from batteries: the gases given off can
cause an explosion.
- If jump-starting another vehicle, position
the jump Leads in such a way that they can­
not come into contact with any moving
parts in the engine compartment of the oth­
er vehicle.
CD CAUTION
Please note that the above method of con­
necting the Leads is intended for jump-start­
ing your vehicle. If jump-starting another ve­
hicle, you should not connect the negative
lead (-) to the negative terminal of the dis­
charged battery, but directly to the engine
block or a solid metal part bolted to the en­
gin e block. If the battery of the other vehicle
does not have a gas vent, there is a risk that a
mixture of oxygen and hydrogen gas can accu­
mulate and cause an explosion.
@ Note
- The battery is vented to the outside to pre­
vent gases entering the vehicle's interior.
- Connect the battery clamps so they have
good metal-to-metal contact with the bat­
tery terminals.
Tow-starting / towing
away
General notes
Some experience is required to tow or tow-start a
vehicle, especially when using a tow-rope. Both
drivers should be familiar with the technique re­
quired for towing. Inexperienced drivers should
not attempt to tow-start or tow away another ve­
hicle.
Do not pull too hard with the towing vehicle and
take care to avoid jerking the tow-rope. When
towing off-road, there is always a risk that the
anchorage points may be overloaded.
Tow-bar / tow-rope
It is easier and safer to tow the vehicle with a
tow-bar. You should only use a tow-rope if you do
250 not
have a tow-bar. It is advisable to use a tow­
rope made of elastic synthetic fibre or similarly
elastic material.
Notes on towing vehicles
The vehicle can be towed with a tow-bar or tow­
rope. When the engine is not running, the gear­
box will not be adequately Lubricated if the fol­
lowing speed/distance restrictions are not ob­
served:
- The vehicle must not be towed faster than
SO km/h.
- The vehicle must not be towed further than
50km.
Additi onal notes on towing by breakdown
truck
If one of the axles has to be raised in order to tow
the vehicle, please refer to the following table to
determine the appropriate axle for your gearbox/
drive combination:

Automatic gearbox Front
axle Front axle
Four-wheel drive: If the vehicle is to be towed
with one of the axles raised, the ignition must be
switched off; otherwise the drive train can be
damaged.
Notes on tow-starting
Automatic gearbox: For technical reasons, your
vehicle must not be tow-started.
Manual gearbox: As a general rule, tow-starting
is not recommended. If the engine will not start,
it is best to try starting it using the battery of an­
other vehicle ¢ page 248 before attempting to
tow start. If this is not possible, you can try to
push-star t or tow-start the vehicle ¢ page 251,
