- 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!

© CAUTION
Do not add coolant if the expansion tank is
empty. Air could have got into the cooling
system - risk of engine damage! In this case,
do NOT drive on. Obtain professional assis­

tance.

- 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.

In right-hand drive vehicles the brake fluid reser­
voir is on the other side of the engine compart­
ment.
Changing brake fluid
Have the brake fluid changed regularly by a quali­
fied workshop.
WARNING
-If the brake fluid Level is under the MIN
mark, the effectiveness of the brakes and
therefore the safety of the vehicle may be
impaired - risk of accident! Do not drive on.
Obtain professional assistance.
- Heavy use of the brakes may cause a vapour
lock if old brake fluid is left in the system.
This would seriously impair the effective­
ness of the brakes and the safety of the car
- risk of accident!

General warnings for batteries
Because of the complexity of the power supply,
any battery work, such as disconnection, replace­
ment, etc. must be carried out by
a
qualified
workshop
^A-

The term "vehicle battery" refers to the 12 Volt
battery in your vehicle.
Explanation of warnings on vehicle battery:

m

Wear safety glasses!
Battery acid is extremely corrosive. Wear
protective gloves and safety glasses.

A

Keep open flames, sparks, uncovered
Lights and lit cigarettes away from the
battery!
A highly explosive mixture of gases may

~\
be given off when the battery is under
charge!
Keep children away from batteries and
battery
acid.

A WARNING
Any work on the batteries and electrical sys­
tem in your vehicLe entails a risk of injury and
chemical burns in addition to danger of
acci­

dent or fire. For this reason, you must have
the work carried out by a qualified workshop.

CA UTION

If the car is left standing for long periods,
protect the battery from frost. The battery
will be damaged irreparably if it is allowed to
freeze

Vehicle battery

The
term "vehicle battery" refers to the 12 Volt
battery in your vehicle.
If the vehicle 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
149. 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 auto­
matically, certain electrical equipment continues
to draw current even when the ignition is off. If
the vehicLe is left standing for long periods, this
can result in total battery discharge. If the
vehi­

cle battery is allowed to discharge completely, an
internal
chemicaL
reaction damages the battery
irreparably. To avoid this, the vehicle battery
should be recharged at Least once a month

^>page
303. PLease contact a qualified workshop
if
you
have any questions.
Winter conditions
Cold weather is very hard on the vehicle battery.
The starting capacity may be reduced as a result.
For this reason, you should have the vehicle bat­
tery checked by
a
qualified workshop before the
start of winter.

ventilated area.
- When it is discharged the vehicle battery
can freeze at temperatures around 0°C. You
must not use a vehicle battery which has

frozen,
even after it has thawed, because
the ice may have cracked the battery casing
and allowed the battery acid to escape - risk
of explosion and chemical burns! Please
contact
a
qualified workshop if
you
have any
questions.
- Do not connect or disconnect the charging
cables during the charging process - risk of

explosion!

Checking and topping up fluids
© CAUTIO
-The anti-freeze concentration must be
matched to the climate of the country in
which you are driving. If the concentration
is too
high,
damage to the car may result.
- Never put in radiator anti-freeze or other
additives.
- Never use washer fluid which contains paint
thinners or solvents as it can damage the
paintwork.
Service interval display

The
service interval display detects when the
next
service
is due
for
your vehicle.
There are two service interval dispLay levels:
- Inspection or oil change reminder: After a cer­
tain mileage, a service reminder will appear in
the instrument cluster dispLay each time the ig­
nition is switched on/off. The distance or time
remaining will be shown briefly.
- Inspection or oil change due: When your
vehi­

cle is due for an inspection, oil change or
both,

the corresponding reminder Inspection
due!,

Oil change due! or Oil change and inspection

due!
will appear briefly after you switch the ig­
nition on/off.
Checking the service intervals
On the infotainment system, you can look up the
distance and time remaining until the next oil
change or next service inspection. Select the
fol­

lowing on the infotainment system:
|MENU|
but­
ton > Car

Service intervals.

Applies
to: vehicles with flexible oil change service
You cannot check the service interval on a new
vehicle until it has been driven for about 500 km.
Qualified workshops reset the service interval af­
ter the oil is changed. The distance to the next oil
change is initially displayed based on the driving
profile prior to the oil change. Your own personal
driving profile is used subsequently to calculate
the remaining distance. Frequent cold starts or
short trips place extra demands on the engine oil
with the result that the oil has to be changed
more often.
Resetting the display
Your qualified workshop resets the service inter­
val display after each service.
It is very important that you reset the oil change
dispLay if
you
change the oil yourself. The
next
oil
change will be due after
a
fixed service interval.
To reset the display, select the following on the
infotainment system:

Reset oil change interval.

(J) CAUTION

- Do not reset the oil change interval display
unless you have changed the oil.
- Keeping to the correct service intervals is
crucial for the operation, service life and re­
sidual value of the vehicle (and especially
for the life of the engine). Services must al­
ways be carried out promptly, even if the
mileage is Low.

WheeLs

Tyres and rims
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.

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 in addition to trained personnel.

•
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
<=> /\.

The sizes of the rims and tyres approved
for
your
vehicle are listed in the vehicle's documents (e.g.

EC
Certificate of Conformity or COC
document1)).

The vehicle documents vary depending on the
country in which the vehicle is registered.
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.
Applies to vehicles with four-wheel drive: All four
wheels must always be fitted with tyres of the
same type, make and tread pattern, as the drive-
line could otherwise be damaged by variations in
the wheel speeds. For the same reason, only use
a spare wheel* which has the same rolling cir­
cumference as the normal road wheels.
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 2016.
Audi Genuine Tyres
Audi Genuine Tyres with the marking "AO" are
specially matched to your Audi. When used prop­
erly, these tyres meet the highest standards in
safety and handling. Your specialist retailer will
be glad to provide more information.
Tyre wear / damage

A
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 effective tyre size can differ signifi­
cantly from the nominal dimensions, even
though the tyres have the same size desig­

nation.
Inadequate tyre clearance can result
in damage to the tyres or the vehicle, caus­
ing 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!

Fig.
252 Tyre tread: Tread wear indicators
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.
252 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
depth1)
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.

Please observe the applicable regulations in the country in
which you are travelling.

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.
A WARNING
Insufficient tread depth or different tread
depths on different wheels reduce safety. This
is particularly evident in vehicle handling,
when there is a risk of aquaplaning in deep
puddles of water and when driving through
corners. Braking is also adversely affected -
risk of accident!

Checking / adjusting the tyre pressures

•
Check the tyre pressures at least once a month

and,
in addition, before starting a long journey.

•
The tyre pressures should only be checked
when the tyres are cold. The slightly raised
pressures of warm tyres must not be reduced.

•
Refer to the sticker

tyre pressures according to the load the vehicle
is carrying.

•
If necessary, adjust the tyre pressure.
• Applies to vehicles with tyre pressure loss

• Check the pressure of the spare
wheeLVcom-

pact temporary spare wheel*. Keep the spare
tyre inflated to the highest pressure approved
for the tyre.
WARNING
Always adjust the tyre pressures to match
your driving style and the load the vehicle is

carrying.

- Excessive Loads can cause you to Lose control
of the vehicle - risk of accident!
- Under-inflated tyres flex more and can over­
heat at high speeds or when the vehicLe is
carrying a heavy Load. This could cause a
tyre blow-out and you could lose control of
the vehicle - risk of accident!
