On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL )
The Ma lfunction Indicator Lamp ( MIL ) ¢'4 in
the instr ument cluster is part of the On-Board
Diagnostic (OBD II) system .
T he wa rni ng/indicator light ill uminates when
the ignit io n is switched on and goes out after
the engine sta rts and the id le has stab ilized.
This indicates that the MIL is working proper­
ly .
If the light does not go out afte r th e en gine
is started, or illuminates while you are dr iv­
ing, a mal function may exist in the engine sys ­
tem.
If the lig ht illum inates, the catalyt ic con­
verter could be damaged .
Contin ue driving
with reduced power (avoid­
ing s ustained high speeds and/or rapid accel­
erations) and have the cond ition corrected.
Contact your aut horized Audi dea ler.
If the light illuminates, the e lectronic speed
limiter may also be malfunct ioning . For more
information
c> page 30, Electronic speed
limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
c> page 216.
On-Board Diagnostics
Fig. 1 6 Location o f Data Li nk Co nnector (D LC)
On-Board Diagnostics monitors the com po­
nents of your emission cont ro l system. Each
monitored component in your engine system
Iii>-

30 Instruments and warning /indicator lights
has been assigned a code. In case of a ma l­
function, the component will be identified
and the fault stored as a code in the contro l
module memory.
The MIL light may a lso illuminate if there is a
leak in the on-board fue l vapor recovery sys­
tem .
If the light illuminates after a refue lling,
stop the vehicle and make sure the fuel filler
cap is properly closed ¢
page 216.
In order to make an accurate diagnosis, the
stored data can only be displayed using spe­
cial diagnostic equipment (generic scan tool
for OBD) .
In order to connect the special diagnostic
equipment, push the plug into the Data L ink
Connector (DLC). The DLC is located to the
right of the hood release¢
fig. 16.
Your authorized Audi dealer or a qualified
service station can interpret the code and per­
form the necessary repair .
A WARNING
Do not use the diagnostic connector for
personal use . Incorrect usage can cause
malfunctions, which can increase the risk
of a coll ision!
Electronic speed limiter
-
Your veh icle may be factory equipped with
tires that are rated for a maximum speed of
130 mph (210 km/h). This is less than the
maximum speed of you r vehicle. To reduce the
risk of sudden tire failure and loss of control if
the vehicle is operated at excessive speeds,
your veh icle also has an electronic speed limit­
er. The electronic speed limiter prevents your
vehicle from go ing faster than the tire speed
rating. For more informat ion ¢
page 257 .
If the engine control unit receives faulty vehi­
cle road speed s ignals, the Malfunction Indi­
cator Lamp (MIU
¢'4 will illuminate. If this
occurs, contact the nearest authorized Aud i
dealer for assistance. S models
Your
vehicle's top speed is elect ron icall y limit­
ed to 155 mph (250 km/h).
If the engine control unit receives faulty veh i­
cle roadspeed signals, the Malfunction Indica­
tor Lam p (MIL)
¢'4 will illuminate . If this oc­
curs, contact the nearest authorized Audi
dealer for assistance.
_& WARNING
-= -
Always observe the posted speed limits
and adjust your speed to suit prevailing
road, traffic and weather cond itions. Never
drive your vehicle faster than the maxi­
mum speed rating of the tires installed .

Power locking system
General description
The power locking system locks or unlocks all
doors and the rear lid simultaneously.
You can lock and unlock the vehicle centrally.
You have the following choices:
- Remote master key¢
page 34,
- Door handles with convenience key*
¢page 35 ,
- Lock cylinder at the driver's door
¢page 36, or
- Power locking switch inside¢
page 36.
Selective unlocking
When you lock the vehicle, the power locking
system will lock the doors and the rear lid.
When unlocking, you can set in the MMI
whether only the driver's door or the entire
vehicle should be unlocked
¢page 34.
Automatic locking
The automatic locking feature locks all the ve­
hicle doors and the rear lid when you drive
faster than 9 mph (1S km/h).
T he car is unlocked again, when the opening
function in the power locking system switch
or at one of the door levers is actuated .
Anti-theft alarm warning system
If the anti-theft alarm warning system de­
tects a break-in into the vehicle, acoustic and
visual warning signals are triggered .
T he anti-theft warning system is activated au­
tomatically when you lock the vehicle . It is de­
activated when unlocking using the remote key, with the mechanical key, and when you
switch the ignition on.
The alarm also turns off when the alarm cycle has expired .
Opening and closing 33
Turn signals
When you unlock the vehicle, the turn signals
flash twice. When you lock the vehicle the
turn signals flash once. If they do not flash ,
one of the doors, the rear lid or the hood is not locked.
Unintentionally locking yourself out
In the following cases there safeguards to
prevent you locking your remote master key in
the vehicle:
- The vehicle does not lock with the central
locking switch¢
page 36 if the driver's
door is open.
- On vehicles with convenience key*, if the
most recently used master key is in the lug­
gage compartment, the rear lid is automati­
cally unlocked again after it is closed.
Do not lock your vehicle with the
remote mas­
ter key or convenience key*
until all doors
and the rear lid are closed. In this way you
avoid locking yourself out accidentally.
Power side door closer*
The vehicle doors are equipped with a power
side door closer. When closing a door, you on­
ly have to let it fall lightly into the latch. The
door will then automatically close by itself
¢..1, .
A WARNING
-

nobody -especially children -should re­
main inside the vehicle. Remember,
when you lock the vehicle from the out­
side the windows cannot be opened from

the ignition key with you . This will pre­
vent passengers (children, for example) from accidentally being locked in the ve­
hicle should they accidentally press the
power locking switch in the doors.
- Do not leave children inside the vehicle
unsupervised. In an emergency it would
be impossible to open the doors from
the outside without the key.
