Checking and topping up fluids
A WARNING
- To avoid the risk of being scalded, never
open the bonnet if
you
see steam or coolant
escaping from the engine compartment.
Wait until no steam or coolant can be seen
before opening the bonnet.
- For safety reasons the bonnet must always
be completely closed when the vehicle is

moving.
After closing it always check that it
is properly secured. It should not be possi­
ble to
lift
the front edges of the bonnet.
Should you notice that the bonnet is not
safely secured when the vehicle is moving,
stop the vehicle immediately and close the
bonnet properly, otherwise it could cause an
accident.

- 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!
Brake fluid
© 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.

you
have any questions.
Battery
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

tery.

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.

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.

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

Care of vehicle and cleaning

A.
WARNING
- Follow the rules and recommendations of
the car wash operator and do not wash the
vehicLe with the ignition switched on - risk
of accident!
- To avoid cutting yourself on sharp metal

parts,
always wear suitable protection when
cleaning the underside of the car or inside
the wheel arches.
- After the car has been washed, the full brak­
ing effect can be delayed by moisture (or in
winter by ice) on the discs and brake pads -
risk of accident! The brakes should be dried
by pressing the pedal to restore full braking
effect.
© CAUTION
- Before washing the vehicle in an automatic
car wash, please make sure to retract the
exterior mirrors to prevent damage. Always
use the electrical power controL to fold the
mirrors in/out on vehicles with electrically
retractable exterior mirrors*.
- Do not wash the vehicle in direct sunlight -
otherwise the paint can be damaged.
- Do not use insect sponges or abrasive
household sponges, etc. - they can damage
the surfaces.
- Matt-painted vehicle parts:
- Do not use polish or wax - otherwise the
paintwork can be damaged.
- Never use car-wash programmes that in­
clude wax coatings. This could spoil the
matt finish.
- Do not attach any stickers or magnet la­
bels to matt-painted parts as these could
damage the paintwork when they are re­

moved.

® For the sake of the environment
The car should only be washed in special wash

bays.
This prevents oily water from getting in­
to the public drains.
