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.

Doors and windows 42Doors and windowsCentral locking systemDescriptionThe vehicle can be locked and unlocked via the central locking
system. You can use any of the following:•
Remote control key ⇒page 47
•
Door handles in conjunction with advanced key* ⇒page 47
•
Lock on driver's door ⇒page 48
•
Interior central locking switch ⇒page 49
Unlocking one side of the vehicle only
When you lock the vehicle, the central locking system will lock the
doors and the boot lid. When you unlock the vehicle, the central
locking system will unlock either the driver's door only, or all the
locks on the vehicle, depending on the setting you have selected on
the sound system or MMI* ⇒page 50.
Automatic locking function (Auto Lock)
The Auto Lock function locks the doors and the boot lid when the
vehicle exceeds a speed of about 15 km/h.
The vehicle is unlocked again when the ignition key is removed.
Alternatively, the vehicle can also be unlocked via the central
locking switch or by pulling one of the inside door handles. The Auto
Lock function can be switched on and off on the sound system or
MMI* ⇒page 50.
In the event of an accident in which the airbags inflate, the doors
will be automatically unlocked to facilitate access and assistance.
Deadlock mechanism
The central locking system is combined with a deadlock mecha-
nism. Once the vehicle has been locked from the outside, the door handles on the inside are deactivated. This makes it more difficult
to break into the vehicle.
Anti-theft alarm system*
If the anti-theft alarm system senses interference with the vehicle it
triggers an audible and visible alarm.
The anti-theft alarm system switches on automatically when the
vehicle is locked. It switches off automatically if you unlock the
vehicle using the remote control.
If you unlock the vehicle by inserting the key in the driver's door, the
ignition must be switched on within 15 seconds, otherwise the
alarm will be triggered. On some export versions, the alarm is trig-
gered immediately when you open a door.
To deactivate the alarm, press the unlock button on the remote
control key or switch on the ignition. The alarm will also switch itself
off when it comes to the end of its cycle.
Switch off the interior monitor and tow-away protection if you wish
to prevent the alarm from being triggered accidentally ⇒page 50.
Turn signals
The turn signals will flash twice when the vehicle is unlocked and
once when the vehicle is locked. If the turn signals do not flash, one
of the doors, the bonnet or the boot lid is still open.
Accidental lock-out
The central locking system prevents you from being locked out of
the vehicle in the following situations:
•
When the driver's door is open, it cannot be locked together with
the other doors by pressing the central locking switch and then
closing the door ⇒page 49.
•
On vehicles with advanced key*, the boot lid will be released
again automatically if the remote control key that was last in use is
left inside the boot when the boot lid is closed ⇒page 51.

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.
