Driver information system 40The tyre pressure monitoring system makes use of the ABS sensors
to compare the rolling circumference and the vibration of the
wheels. The display in the instrument cluster alerts the driver if
changes are detected on one or more wheels. If only one tyre is
affected, the display will indicate its position ⇒fig. 27.
Each time you change a tyre or the tyre pressures on your vehicle,
you must store the new tyre pressures via the sound system or
MMI* ⇒page 41.
The rolling circumference and vibration can change if:•
The tyre pressure is too low
•
The tyre has suffered structural damage
•
The air pressure in one or more tyres was changed and the new
tyre pressures were not stored ⇒page 41, “Storing the tyre pres-
sures”
•
The wheels were changed and the new tyre pressures were not
stored ⇒page 41, “Storing the tyre pressures”
•
There is a greater load on the wheels of one axle (e.g. if you are
carrying more passengers or luggage)
•
The road surface under the left wheels is different to the road
surface under the right wheels for a long period
Warning lamp
 / TPMS Tyre pressure ! System malfunction
If the warning lamp  flashes for about a minute and then remains
lit after you switch on the ignition, there is a fault in the system. TPMS (Tyre Pressure Monitoring System) Tyre pressure ! System
malfunction ⇒page 40, fig. 28 will also be displayed in the instru-
ment cluster. Please contact the nearest qualified workshop as soon
as possible.
WARNING
•
If the tyre pressure warning lamp appears in the instrument
cluster display, slow down immediately and avoid any severe
braking or steering manoeuvres. As soon as you can do so safely,
stop and check the tyres and the tyre pressures.
•
It is the driver's responsibility to ensure that the tyre pressures
are correct. For this reason you must check the tyre pressures
regularly.
•
Under certain conditions (e.g. driving at high speeds, on ice and
snow or on poor road surfaces) the tyre pressure warning lamp
may not light up immediately or not at all.
•
Please ask your Audi dealer or qualified workshop whether run
flat tyres can be used on your vehicle. Unauthorised use of these
tyres can invalidate the vehicle's type approval for use on public
roads. Furthermore, this could cause damage to your vehicle and
possibly also result in an accident.

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
