On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL )
The Ma lfunction Indicator Lamp (MIL) ¢• in
the instr ument cluste r is part of the On-Board
Diagnost ic (O8D
II) system .
T he warning/i ndicator light ill uminates when
the ignit ion is switched on and goes out after
the engine starts and the id le has stabilized .
This indicates that the MIL i s working proper­
ly.
If the light does not go out after the engine
is started, or illuminates while you are driv­
ing, a malfunction may exist in the engi ne sys­
tem.
If t he light illuminates, the ca talytic con­
verter could be damaged .
Continue driving
with reduced power (avo id­
ing sustained high speeds and/or rapid accel­
erations) and have the cond ition corrected .
Contact your authorized Audi dea ler .
I f the light illuminates, the electronic speed
limiter may also be malfunct io ning . For more
informa tion
c> page 30 , Electronic speed
limiter* .
If the fuel filler cap is closed incorrectly, this
may also cause the MIL to turn on
c> page208.

Electronic speed limiter*
Applies to vehicles: electro nic speed li miter
Your veh icle may be facto ry equipped with
tires that a re rated for a maxim um speed of
130 mph (210 km/h). This is less than the
maximum speed of your vehicle. To reduce the
risk of s udden tire failure and loss of control if
the vehicle is operated at excessive speeds,
your ve hicle also has an electronic speed limit­
er. The electronic speed limiter prevents your
vehicle from go ing faster than the tire speed
rating . For mo re informat io n ~
page 236 .
If the engine control unit rece ives fa ulty vehi­
cle road speed s ignals, the Malfunction Ind i­
cator Lamp (MIU
¢'4 will illuminate . If th is
occurs, con tact the nearest aut horized Aud i
dea ler for assistance.

cle. Otherwise the children could start
the engine or operate electrical equip­
ment such as power windows.
- Do not remove the key from the ignition
lock until the vehicle has come to a com­
plete stop. Otherwise, the steering col­
umn lock could engage suddenly and in­
crease the risk of an accident.
{i) Tips

can be temporarily disrupted by interfer­
ence from transmitters in the vicinity of
the veh icle working in the same frequency
range (for example, a cell phone or radio
equipment).
Central locking system description
You can lock and unlock the vehicle centrally .
There are different ways, depending on vehicle
equipment:
- Remote control key¢ page 33

32 Opening and closing
Selective unlocking
The doors and rear lid lock when they close.
You can set in the MMI whether
only the driv­
er's door or the entire vehicle should lock
when closing
c::> page 36.
Automatic locking (Auto Lock)
The Auto Lock funct ion locks all doors and the
l uggage compartment lid once the speed has
exceeded approximately 9 mph (15 km/h) .
The car is un locked again once the ignition key
is removed. In addition, the vehicle can be un­
l ocked if the opening function in the power
locking system switch is used or one of the
door handles is pulled. The Auto Lock function
can be turned off or on in the MMI
c::>page36.
In the event of a crash with airbag dep loy ­
ment, the doors automatically unlock to allow
access to the vehicle.
Anti -theft alarm system*
If the anti-theft alarm system detects a vehi­
cle break-in, audio and visual warning signa ls
are triggered .
The anti-theft alarm system turns on auto­ mat ica lly when you lock the vehicle.
It deacti­
vates when un locking using the remote con­
trol key or by touching the sensor on the door
handle (convenience key).
To switch the alarm off, press them button on
the remote control key or convenience key or
switch the ignition on . The alarm also stops
automatically after a certain amount of time.
Turn signals
The turn signals flash twice when you unlock
the vehicle and once when yo u lock the vehi­
cle.
If they do not flash, one of the doors, the lug­
gage compartment lid or the hood is not
lock ed or the ignition is still sw itched on (the
latter applies to vehicles with a convenience
key) .
Unintentionally locking yourself out
The following situat ions prevent you from
locking your remote control key in the vehicle:
- The vehicle does not lock w ith the cent ral
lock ing switc h if the driver's door is open
c::>page3 5.
-On veh icles with a convenience key*, the lug­
gage compartment lid unlocks again after
clos ing if the most recent ly used key is in
the luggage compartment.
Do not lock your veh icle w ith the remote con­
trol key or convenience key* until all doors and
the luggage compartment lid are closed. This
helps to prevent from locking yourself out ac­
cidentally .
(D Tips
-Do not leave va luab les unattended in the
vehicle. A locked vehicle is not a safe!
- If the LED in the upper edge of the driv­
er's door turns on for about 30 seconds
after the vehicle is locked, there is a mal­
function in the power locking or the anti­
theft alarm system*. Have the problem
corrected by an authorized dealer or
qualif ied repair facility.
- The interior monitor ing of the anti-theft
alarm system* only operates correctly if
the windows and the sunroof* are closed.
