 Key not in vehicle
This message will appear together with the symbol
 if the remote
control key is removed from the vehicle while the engine is running.
This is to remind you not to continue driving without the key (for
example if you change drivers).
If the remote control key is not in the vehicle you will not be able to
switch on the ignition or restart the engine after it has been
switched off. You will also not be able to lock the vehicle from the
outside.
Light sensor/ rain sensor defective

 Automatic headlights/ automatic wipers defective
If the  symbol appears, this means that the light sensor/ rain
sensor is not functioning. For safety reasons, the dipped beam
headlights will then be switched on permanently when the light
switch is set to the AUTO position. However, you can still switch the
lights on and off in the normal way with the light switch. If the rain
sensor is defective, the functions operated via the windscreen wiper
lever will still be available. You should have the light sensor/ rain
sensor checked by a qualified workshop as soon as possible.

WARNING
•
Always switch off the ignition and take the key with you when
leaving the vehicle - even if you only intend to be gone for a short
time. This is especially important if children are left in the car. They
might otherwise be able to start the engine or use power-operated
equipment such as the electric windows - this could lead to inju-
ries.
•
Wait for the vehicle to come to a standstill before removing the
ignition key from the lock. Otherwise the steering lock could
engage suddenly, causing an accident.Note
The function of the remote control key may be impaired by interfer-
ence from other nearby radio signals (for example from a mobile
telephone or TV transmitter) if these are in the same frequency
range.Indicator lamp on remote control key
The indicator lamp on the remote control key lights up
when you press the buttons.
The indicator lamp should light up once briefly when you press one
of the buttons briefly. The indicator lamp should flash when you
press and hold one of the buttons (convenience open/close).
If the indicator lamp does not light up, this means the battery is
exhausted and must be replaced ⇒page 39. The instrument cluster
display also shows the symbol
 and the following message if the
battery is exhausted:
Please change key battery
Replacing the battery for the remote control key
Each remote control key contains a round-cell battery,
located in the battery carrier.

Heating and coolingDeluxe automatic air conditionerApplies to vehicles: with deluxe automatic air conditionerDescription
The air conditioner can be used to set a comfortable inte-
rior temperature in the vehicle.The air conditioner provides heating and ventilation and also cools
and dehumidifies the air inside the vehicle.
The air conditioner is fully automatic and will maintain the desired
temperature at a constant level. To achieve this, the temperature of
the air supplied to the interior, the blower speed (volume of air
delivery) and the air distribution are regulated automatically. The
system also allows for the effect of strong sunlight, so there is no
need for manual adjustment. For these reasons it is advisable to use
the automatic mode for the comfort of all the passengers in virtually
all conditions throughout the year ⇒page 93.
Please note:
The humidity of the air is automatically reduced when the system
cools the interior of the vehicle. This helps to prevent condensation
on the windows.
If the humidity and temperature outside the vehicle are high,
condensation can drip off the evaporator in the air cooling system
and form a pool underneath the vehicle. This is normal and does not
indicate a leak.
If the outside temperature is low, the blower normally only switches
to a higher speed once the coolant has warmed up sufficiently (this
does not apply to the defrost setting).
In order to achieve maximum engine power, the air conditioner
compressor is temporarily switched off when pulling away from a
standstill with full throttle.The compressor also switches off if the coolant temperature is
excessively high, to ensure adequate engine cooling under extreme
loads.
Pollution filter
The pollution filter (a particle filter) serves as a barrier against impu-
rities in the outside air, including dust and pollen, and odours. The
air is also filtered when the air recirculation mode is activated.
For the air conditioner to work with maximum efficiency, the pollu-
tion filter element must be replaced at the intervals specified in the
Service Schedule.
If the vehicle is driven in areas with a high level of air pollution and
the filter is no longer fully effective, it may be necessary to change
the filter element more frequently.
Key-coded settings
The currently selected air conditioner settings are automatically
stored and assigned to the remote control key.
Power management
To prevent the battery from becoming discharged and to maintain
the necessary power level, the system will temporarily shut off the
electrical components that are using a lot of power, or reduce the
current they are consuming ⇒page 192. Heating systems in partic-
ular use a large amount of electrical power. If you notice, for
instance, that the rear window heater is not working, it may have
been temporarily switched off by the power management function,
or regulated to a lower heat output. These systems will be available
again as soon as sufficient electrical power is available.

Downloaded from www.Manualslib.com manuals search engine Checking and topping up fluids 228
For the sake of the environmentIf 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 166.
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 192.Please note that certain convenience features, such as the Audi
advanced key*, the remote control key or the electrical seat adjust-
ment may not be available when you unlock the vehicle. These func-
tions will be restored when you switch on the ignition and start the
engine.
Winter conditions
At low temperatures the battery has to work very hard. It also
provides only a fraction of the starting power it has at normal
temperatures.
For this reason, we recommend having the battery checked and
charged if necessary before the start of winter ⇒page 230.
WARNING
•
All work on batteries requires specialist knowledge. For queries
regarding the vehicle battery please contact an Audi dealership or
other qualified workshop (risk of chemical burns / risk of explo-
sion).
•
The battery must not be opened. Do not attempt to make any
changes to the electrolyte level of the battery. Otherwise, there is
a risk that a mixture of oxygen and hydrogen gas can accumulate
and cause an explosion.Note
If the vehicle is to be left standing for a period of several weeks at
extremely low temperatures, the battery should be removed from
the vehicle. This ensures that it cannot “freeze up” and be
damaged.
