Instruments and warning/indicator lamps 12Warning symbol in instrument cluster
If the symbol
lights up in the display, this means that either the
coolant temperature is too high or the coolant level is too low
⇒page 33.
If the needle is at the top end of the dial, this means the coolant
temperature is too high. Stop the vehicle, switch off the engine and
wait for it to cool down. If the warning lamp starts flashing again
after just a short distance, contact a qualified workshop.
WARNING
•
Before opening the bonnet and checking the coolant level,
please observe the warning information on ⇒page 255, “Working
on components in the engine compartment”.
•
Never open the bonnet if you can see or hear steam or coolant
escaping from the engine compartment; there is a risk of being
scalded. Wait until you can no longer see or hear escaping steam
or coolant.Caution
•
Additional lights and other accessories in front of the air inlet
reduce the cooling effect of the radiator. At high outside tempera-
tures and high engine loads, there is a risk of the engine over-
heating.
•
The front spoiler also ensures proper distribution of the cooling
air when the vehicle is moving. If the spoiler is damaged this can
reduce the cooling effect, which could cause the engine to overheat.
You should obtain professional assistance.
Rev counter
The rev counter indicates the number of engine revolu-
tions per minute.You should select a lower gear if the engine speed drops below
1500 rpm. The start of the red zone on the dial indicates the
maximum engine speed which may be used briefly when the engine
is warm and after it has been run in properly. However, it is advisable
to change up a gear or move the selector lever to “D” (or lift your
foot off the accelerator) before the needle reaches the red zone.
Caution
Never allow the rev counter needle ⇒page 11, fig. 2 to go into
the red zone on the dial for more than a very brief period: there is a
risk of damaging the engine. The start of the red zone on the dial is
different for some engine versions.
For the sake of the environment
Changing up a gear early will help you to save fuel and minimise
engine noise.

Driver information system 24Door catches / boot lid warning
The pictogram shows whether the doors and the boot lid,
etc. are properly closed when driving off.The door catches/boot lid warning symbol lights up if one or more
of the doors, or the bonnet or boot lid are not properly closed when
the ignition is on. The symbol also indicates which of these is not
properly closed ⇒fig. 14.
The warning symbol disappears when all the doors, the bonnet and
the boot lid are completely closed, and the driver information func-
tions selected will then be displayed again.
Service interval display
The service interval display detects when the next service
is due for your vehicle.You can see whether an oil change or service inspection is due in
the Car menu on the sound system or MMI display. There are two
display levels:•
Service reminder: When the next service date is approaching,
Service in----- km--- days ⇒fig. 15 will be shown in the instrument

Service due: When a service is due, Service due! will appear in
the display as soon as you switch on the ignition. The display reverts
back to the standard display after a short time. In addition, a tone
will sound.
Displaying distance and time to next service
In the Car menu, you can look up the distance and time remaining
until the next oil change and next service inspection. To do this,
select function selector button > Service interval display
⇒page 24, fig. 16.
The display may not be complete on new vehicles within the first
500 km.
Resetting the service interval display
Your Audi dealer resets the display after each service. You can only
reset the oil change display yourself. To do this, select function
selector button > Service interval display > Reset oil change
interval. The next oil change will be indicated as being due
15,000 km or one year (fixed service interval) after the oil change
interval is reset.Caution
The system cannot calculate the figures for the service indicator if
the battery is disconnected from the vehicle, so no service reminder
can be displayed during this time. Please remember that keeping to
the correct service intervals is most important for the service life
and residual value of the vehicle (and especially for the life of the
engine). The period between two services must never be longer
than the time specified in the Service Schedule, even if you only
cover a low mileage during this time.
Note
•
Do not reset the display between oil changes - otherwise the
display will be incorrect.
•
The information in the service interval display remains intact if
the battery is disconnected.
•
The distance to the next service cannot be called up if the system
has detected a Priority 1 fault (red symbol).
•
If the service was not performed by a qualified workshop, the oil
change interval display can only be set to “fixed service intervals” of
15,000 km. If you wish to continue with the “LongLife” service, you
will need to have the oil change interval display reset by a qualified
workshop.

Audi side assist 150
Switching on
– Press the button ⇒page 149, fig. 165. The red indicator
lamp in the button will light up.
Switching off
– Press the button again. The indicator lamp in the button
will go out.The system is designed to provide assistance on motorways and
other out-of-town roads, so it only operates at speeds above about
60 km/h.
WARNING
•
Please note that the sensors are not always able to detect all
vehicles which may represent a potential hazard (accident risk).
•
Please note that the side assist is not able to give adequate
warning of vehicles approaching very fast from behind, or vehicles
that you are overtaking rapidly.
•
The radar sensor's "field of vision" can be impaired by rain,
snow or a lot of water on the road. This results in vehicles not
being reliably recognised or, in some circumstances, not being
detected at all by the side assist. Always give your full attention to
the position of your vehicle on the road and other nearby traffic.
•
The side assist only gives a warning of approaching vehicles
and vehicles in the blind spots when road speed is above 60 km/h.
•
Please note that the side assist does not operate in tight bends
(with a radius of less than 200 metres).
•
The side assist feature is not a substitute for the full concentra-
tion of the driver. The driver is always responsible for the safety of
lane changes and other manoeuvres. Always give your full atten-
tion to the position of your vehicle on the road and other nearby
traffic.
Caution
•
To avoid impairing the function of the side assist, do not attach
any objects (e.g. stickers or bicycle carriers) in such a way that they
might interfere with the radar sensors in the rear bumper.
•
Make sure that the warning lamps on the exterior mirrors are not
obscured by stickers or other objects.Note
•
To ensure that the side assist function works properly, do not
allow snow and ice to accumulate on the rear bumper near the radar
sensors. Please observe the additional notes on ⇒page 157.
•
The side assist function will be switched off automatically when
the electrical connector for the trailer socket is plugged in on vehi-
cles with a factory-fitted towing bracket.
•
The side assist should be switched off manually when towing a
trailer if the vehicle is equipped with a towing bracket which was not
factory-fitted.
•
The side assist system will switch off automatically if it detects
an obstruction that impairs the function of the radar sensors.
•
The warning lamps on the exterior mirrors may not be properly
visible if tinted foil is affixed to the side windows on the driver's or
passenger's side.

Engine oilGeneral notesWe recommend that you have the oil change carried out by an Audi
dealership / qualified workshop according to the intervals stated in
the Service Schedule or according to the service interval display in
the instrument cluster.
Whether your vehicle is serviced at flexible service intervals or fixed
service intervals is shown in the Service Schedule.
The correct oil specifications for your engine are listed in the Te c h -
nical data section ⇒page 323, “Performance, weights and dimen-
sions”.
Check that the specifications quoted (VW standards) appear on the
container either singly or in combination with other specifications.
Flexible service intervals (Audi LongLife Service*)
Special engine oils ⇒page 323, “Performance, weights and dimen-
sions” have been developed as part of the Audi LongLife Service
(⇒“Service Schedule”).
This type of oil must be used if you intend to take advantage of the
extended maintenance intervals allowed by the Audi LongLife
Service.•
Do not mix the LongLife oil with oil intended for fixed service
intervals, as the requirements for the extended service intervals are
then no longer guaranteed.
•
In exceptional circumstances, if the engine oil level is too low
⇒page 258 and you cannot obtain the specified LongLife oil, you
can put in a small quantity of oil for fixed service intervals -
⇒page 323, “Performance, weights and dimensions”. This should not be done more than once and no more than 0.5 litres should be
used.
Fixed service intervals (Inspection Service)*
If you do not take advantage of the LongLife service for your car, you
can use the oils for fixed service intervals - ⇒page 323, “Perform-
ance, weights and dimensions”. In this case, your car must be serv-
iced after a fixed interval of 1 year / 15,000 km (9,000 miles) – see
Service Schedule.
•
In exceptional circumstances, if the engine oil level is too low
⇒page 258 and you cannot obtain the oil specified for your vehicle,
you can put in a small quantity of oil conforming to the specification
ACEA A2 or ACEA A3 (petrol engines) or ACEA B3 or ACEA B4 (diesel
engines). This should not be done more than once and no more than
0.5 litres should be used.
Vehicles with diesel particulate filter*
The Service Schedule states whether your vehicle is fitted with a
diesel particulate filter.
•
Vehicles with diesel particulate filter must only be filled with
engine oil VW 507 00. This oil can be used regardless of whether the
vehicle is serviced at flexible service intervals (Audi LongLife
Service) or fixed service intervals.
•
Avoid mixing this oil with other engine oils.
•
In exceptional circumstances, if the engine oil level is too low
⇒page 258 and you cannot obtain the oil specified for your vehicle,
you can put in a small quantity of oil conforming to the specification
VW 506 00 / VW 506 01 or VW 505 00 / VW 505 01 or ACEA B3 /
ACEA B4. This should not be done more than once and no more than
0.5 litres should be used.

Checking and topping up fluids 260
Caution•
The oil level must never be above area ⇒page 258, fig. 254,
as this may result in damage to the catalytic converter or to the
engine. On vehicles without an oil dipstick, you can check the oil
level via the sound system or MMI*. Contact a qualified workshop to
extract the engine oil if necessary.
•
No additives should be used with engine oil. Any damage caused
by the use of such additives 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 systemCoolant
The purpose of the coolant is to carry heat away from the
engine. The correct amount of anti-freeze is important to
prevent the cooling system from freezing in winter.The cooling system is filled for life at the factory, so the coolant does
not need to be changed. The coolant consists of a mixture of water
and anti-freeze additive G12++. This is a glycol-based anti-freeze
with anti-corrosion additives.
Anti-freeze additive
The amount of anti-freeze additive required depends on the temper-
atures to be expected in the winter season. If the anti-freeze concen-
tration is too low the coolant can freeze, resulting in failure of the
cooling system and heater.The cooling system is filled at the factory with the correct amount of
anti-freeze for the country concerned.
In most cases the mixture consists of 60% water and 40% additive.
This mixture gives the required anti-freeze protection at tempera-
tures down to -25 °C and protects the alloy parts of the cooling
system against corrosion. It also prevents scaling and raises the
boiling point of the coolant.
Countries with warm climate
The coolant concentration must not be reduced by adding plain
water, even in the summer or in warm climates. The concentration
of the anti-freeze additive must always be at least 40%.
Countries with cold climate
If greater anti-freeze protection is required in very cold climates, the
proportion of the anti-freeze additive G12++ can be increased. A
concentration of 60% offers protection down to about - 40 °C. The
concentration of the anti-freeze additive must not be more than
60%, otherwise this would reduce the anti-freeze protection. In addi-
tion, the cooling effect will be adversely affected.
Vehicles for export to countries with a cold climate (such as Sweden,
Norway and Finland) are supplied with antifreeze protection down
to about -35 °C. The concentration of the antifreeze additive for
these countries should always be at least 50%.
Caution
•
It is advisable to have the cooling system checked before the
winter season to make sure that the antifreeze concentration is
adequate for the conditions to be expected. This applies particularly
if you intend to take the car into a colder climate zone. If necessary,
have the anti-freeze concentration increased to 50 - 60% as required.
•
Use only anti-freeze additive G12++, an additive meeting the
specification “TL 774 G”. Other additives may give considerably
inferior corrosion protection. The resulting corrosion in the cooling
system can lead to a loss of coolant, causing serious damage to the
engine.

Changing brake fluid
When required, the brake fluid should be changed by a
competent mechanic with the proper equipment.Brake fluid gradually absorbs moisture from the atmosphere. If the
water content in the brake fluid is too high, this may cause corrosion
in the brake system over time. In addition, the boiling point of the
brake fluid will be considerably reduced. This could adversely affect
the braking ability in certain circumstances.
For this reason the brake fluid must be changed periodically.
Your vehicle's Service Schedule will tell you when the brake fluid has
to be changed.
It is advisable to have the brake fluid changed as part of a regular
Inspection Service at your Audi workshop. They are familiar with the
procedure and have the necessary special tools and spare parts as
well as the proper facilities for disposing of the old fluid.
Use only the genuine brake fluid specified by the factory Qualified
workshops know that the brake fluid “DOT 4” is approved by Audi.
The brake fluid must be fresh and unused.
WARNING
•
Brake fluid is poisonous; store it in the sealed original container
in a safe place out of 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 acci-
dent.Caution
Please note that brake fluid will attack the paintwork on contact.
For the sake of the environment
If the fluid has to be drained out of the brake system, use an appro-
priate container to catch the used brake fluid and dispose of it in the
proper manner.BatteryGeneral notes
All work on batteries requires specialist knowledge.The battery is virtually maintenance-free. It is checked as part of the
Inspection Service.
We recommend that you replace a battery once it is older than 5
years.
When an airbag is triggered, the battery will, under certain circum-
stances, be disconnected from the on-board power supply for
safety reasons ⇒ in “General notes on airbag system” on
page 201.
Disconnecting the battery
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 necessary.
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 reli-
able starting even after a long period ⇒page 226.
