On-Board Diagnostic
system (OBD)
System indicator light (MIL)
The system indicator ligh t (M IL) ¢.§ in the in ­
str ument cl uster is part of the On Board Diag­
nostic System (OBD II).
T he warni ng/i ndicator light t urns on when the
ignition is sw itched on and t urns off once the
engine is sta rted and is runn ing in id le at a
stab le speed. This indicates that the MIL is
funct ioning correct ly.
If the light does not turn off after sta rting
the engine
or turns on while driving, t his may
indicate there is a ma lfunction in the engine.
If the indicator turns on, the cata lytic convert­
er may be damaged .
Drive
with reduced engine performance
(avoid high speeds for extended periods of
time and/or fast acceleration) and have the
malfunction corrected. See an authorized Audi
dealer or author ized Audi Service Facility.
The indicator may turn on if the electronic
speed limiter is faulty. For addit ional informa­
tion, refer to Q
page 30, Electronic speed
limiter* .
The MIL may also turn on if the fuel filler cap
is not closed cor rectly
q page 212.

monitored component in your engine system
has been assigned a code . In case of a mal­
function, the component will be ident ified
and the fau lt stored as a code in the control
module memory .
The MIL light may also illuminate if there is a
leak in the on-board fue l vapor recovery sys­
tem.
If the lig ht illuminates after a refuelling ,
stop the veh icle and ma ke sure the fuel filler
cap is proper ly closed
<> page 212.

Electronic speed limiter*
Applies to vehicles: with electronic speed limiter
Your vehicle may be factory eq uipped w ith
t ir es that are rated fo r a max imum speed of

your vehicle a lso has an electronic speed limit­
er . The elec tronic speed limi ter prevents your
vehicle from going faster than the tire speed rating . For more information ¢
page 248.
If the engine control unit receives faulty veh i­
cle road speed signa ls, the Malfunction Ind i­
cator Lamp (M IL)
¢..fi will illuminate . If this
occurs, contact the nea rest authorized A udi

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 unlock
when unlocking
¢ 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 on or off* 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 ically when you lock the vehicle.

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 .
