Technical data To prevent yourself from being locked out, do not lock the vehicle
with the remote control key before closing the doors or boot lid. If
you accidentally press the locking button on your remote control
key when any of the doors (except for the driver's door) are open,
then put the key down inside the car and forget to take it with you
when you close the doors, you can still open the doors for about one
minute before the vehicle is locked.
WARNING
Do not leave anyone (especially children) in the car if it is locked
from the outside and the deadlock mechanism is activated: the
doors and windows cannot then be opened from the inside.
Locked doors could delay assistance in an emergency, potentially
putting lives at risk.
Note
•
Never leave any valuable items in the vehicle unattended. Even a
locked vehicle is not a safe.
•
If the diode on the driver's window sill lights up for about
30 seconds when the vehicle is locked, the central locking system or
anti-theft alarm* is not working properly. Please have the malfunc-
tion repaired by an Audi dealer or qualified workshop.
•
The interior monitor of the anti-theft alarm* system will only
function as intended if the windows and the tilting panorama roof*
are closed.
Set of keys Remote control key
The remote control key will lock and unlock the car and start the
engine.
Spare key
The spare key is intended for temporary use only and should be
used only in an emergency. Keep it in a safe place and do not carry
it on the keyring.
Replacing a key
If you should lose a key, please contact an Audi dealer. Have the
remote control coding for that key deactivated. For this purpose you
should bring all available keys with you. It is also important to notify
your insurance company if a key has been lost.
Electronic immobiliser
The immobiliser is designed to prevent unauthorised persons from
driving the vehicle. If an uncoded key is used, SAFE will appear in
the mileage recorder display.
It may not be possible to start the engine with the key if there is
another ignition key from a different make of vehicle on the same
key ring.

Doors and windows 44Data stored on remote control key
Data related to the service and maintenance of the vehicle are
stored continuously on your remote control key. Your Audi dealer
can read out the data and will then be able to tell you what service
work is required. This also applies to vehicles with advanced key.
Personal convenience settings
If two people use the same car regularly, it is a good idea for each
person to have his or her “own” remote control key. When you
switch off the ignition or lock the vehicle, your personal settings for
the following convenience features are stored and assigned to the
remote control key:•
Air conditioner
•
Central locking system
•
Windows
•
parking system*
•
adaptive cruise control*
•
Audi drive select*
•
Seat memory*
The stored settings are then recalled automatically the next time the
vehicle is unlocked, the doors are opened or the ignition is switched
on.
WARNING
•
Always 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 injuries.
•
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 45. The instrument cluster
display also shows the symbol
 and the following message if the
battery is exhausted:
Please change key battery

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 95.
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 226. 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.
WARNING
For safety reasons it is important that all the windows are kept
free of ice, snow and condensation. These can cause poor visibility
