press the release button
q fig. 16 -arrow-.
Remote control key or convenience key
The convenience key is a vehicle remote con ­
trol key with special functions
q page 34,
Locking and unlocking with the convenience
key and q page 78, Star ting and stopping
the engine (vehicles with a convenience key).
With the remote control key, you can lock and
un lock the vehicle centrally and start the en­
gine.
Number of keys
You can check the number of keys assigned to
your vehicle in the MMI. This allows you to
make sure you have received a ll of the keys
when you purchase a used vehicle. Select: the
I MENU I button > Car> Systems* control but­
ton
> Programmed keys.
Replacing a key
If a key is lost, see an authorized Audi dea ler
or qualified repair facility. Have this key deac­
tivated. It is important to bring all keys with
you.
If a key is lost, you should report it to
your insurance company .
Immobilizer
The immobilizer prevents unauthorized use of
the vehicle . The vehicle may not start if anoth -

cle or a transponder is located on the key ring.
Data in the remote control key or
convenience key
While driving , service and maintenance -rele ­
vant data is continuously stored on your re­
mote control key or convenience key*. Your
Audi serv ice advisor can read out this data and
tell you about the work your vehicle needs.
_& WARNING
- Always take the vehicle key with you
when leaving the vehicle, even for a
short period of time. This applies partic­
ularly when children remain in the vehi­
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 lock
could engage sudden ly and increase the
risk of an accident.
{i) Tips
The operation of the remote control key
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:

A WARNING
- Never turn off the eng ine before the ve­
hicle has come to a complete stop . The
full function of the brake booster and the powe r steering is not guaranteed. You
must use more fo rce to turn or brake, if
necessary. Because you cannot steer and
brake as you usually would, this could
lead to acc idents and se rious injuries.
- Never remove the ign ition key from the
ign ition lock whi le the vehicle is movi ng .
Otherwise, the steering lock co uld sud­
denly engage and you would not be able
to steer the vehicle.
- Please note that the brake booster and
power steering only work when the en­
gine is runn ing. When the engine off, you
must use more force to steer or brake
the vehicle. Because t he usual steering
and braking capability is not available,
the risk of accidents or injuries increases .

when leaving the veh icle, even for a
short per iod of time. This applies partic­
ularly when chi ldren remain in the vehi­

the engine or operate electrical equip ­
ment such as power windows .
- For safety reasons, always park the vehi­
cle with the selector lever in the P posi- tion. Otherwise, there is the risk t
hat the
veh icle could roll.
- After the engine has been switched off,
the radiator fan can continue to run for
up to 10 minutes -even with the ignition
sw itched off. It can also sw itch on again
after some t ime if the coolant tempera­
ture rises as a resu lt of heat buildup or if
the engine compartment is heated by
sunlight and the engine is hot.
(D Note
- If the engine has been under heavy load
for an extended per iod of t i me, heat
builds up in the engine compartment af­
ter the engine is switched off - there is a

188 Smart Technology
Smart Technology
Information about
data recorded by
vehicle control
modules
Your vehicle is not equipped with a crash data
recorder. This device is insta lled by some vehi­
cle manufacturers to record data about crash ­
es so tha t it can be analy zed later. Crash data
recorders are also called "Event Data Record­
ers (EDR)" .
In some legal jurisdictions, it is not permitted
to access or download data recorded by pre­
installed crash data recorders in order to eval­
uate a crash without clear consent of the vehi ­
cle owner .
Your veh icle is not equipped with a crash data
recorder. However it does contain a var iety of
e lectronic control modules for various vehicle
systems such as eng ine funct ion, exhaust
treatment or airbags and safety belts .
These electron ic control modules record vehi­
cle data during normal driv ing for diagnosis
and repair purposes. The recording capab ility
of the electron ic control modules is lim ited to
data only- no sound is reco rded.
If t he control
mo dule detects a sys tem m alfu nction or other
change in sta tus, a very lim ited amount of da­
ta is recorded for an extreme ly sma ll period of
time . Data t hat is recorded in s uch a case may
include veh icle speed, driving direction, the
load on the brakes and head restraints and
performance in the event of an acc iden t or
other change in status . The stored data can
only be read o r down loaded w ith specia l dev i­
ces.
Electronic stabilization
control (ESC)
Description
The E lectronic Stabilization Cont rol (ESC) con­
tr ibutes to d river safety. It reduces the risk of
slipp ing and improves driving stability. ESC detects critical situations such as the veh
icle
oversteering and understeering or the whee ls
are spinning . The vehicle is stabilized by ap­
plying the brakes or reducing engine torq ue.
Once the ESC is activated, the ind icator light
Bl blinks in the instrument cluster .
The following systems are integrated in the ESC:
Anti -lock braking s ystem (ABS)
ABS prevents the whee ls from locking when
braking . The vehicle can still be steered even
during hard braking . App ly steady pressure to
the brake peda l. Do not pump the peda l. A
puls ing in the brake peda l ind icates that the
system is act ing to stabilize the ve hicle.
Brake assi st sy st e m
The brake assist system can decrease braking
distance .
It increases braking power when the
driver presses the brake peda l quickly in emer­
gency s ituations. You m ust press and hold the
brake pedal until the dangerous situation is
over . In vehicles with adaptive cruise control*,
the brake assist system is more sens it ive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regu lation (ASR )
ASR reduces engine power when the drive
wheels begin sp inning and adapts the force to
the road conditions. This makes it easier to
sta rt , accelerate and dr ive up inclines .
Electronic differenti al lock (EDL )
The EDL brakes whee ls that are spinning and
transfers the drive power to the other drive
wheel or wheels if the vehicle is equ ipped with
all wheel drive *). This function is not ava ilable
at h igher speeds .
In extreme cases, EDL automatically sw itches
off to keep t he b rake on the braked wheel
from overheat ing. The ve hicle is still working
co rrect ly. EDL w ill switch o n aga in automat i­
ca lly when cond itions have ret urned to no r-
mal. .,._
