Speed warning system
Overview
The speed warning system helps you to keep
your driving speed below a set speed limit.
Fi g. 22 Display: speed warning system
The speed warning system warns the drive r if
he exceeds a previo usly stored max imum
speed. A warning tone will sound as soon as
the vehicle speed exceeds the set speed by
about 3 mph (3 km/h). At the same time, a
warning symbol appears in the display
q fig. 22.
The speed warning system has two warning
t hr es hol ds
that function independently of
each other and that have somewhat different
purposes:
' 8/8 ( Canad a model s) Sp eed warn ing 1
You can use speed warning 1 to set the maxi ­
mum speed while you are driving. This setting
will remain in effect until you turn
off the igni­
tion, assuming that you have not changed or reset the setting.
The speed warning symbol
Ci] ; [i (Canada
models) in the warning 1 disp lay appears
when you exceed the maximum speed.
It goes
out when the speed falls below the stored
maximum speed .
The speed warning symbol will also go out if
the speed
exceeds the stored maximum speed
by more than about 25 mph (40 km/h) for at
least 10 seconds. The stored maximum speed
is de leted.

~ To fold the key out and back in place, press
the re lease button~
fig. 26.
The transmitter and battery are located in the
h ead of the remote control. The receiver is lo­
cated inside the vehicle. The maximum effec­
tive range depends on seve ral things. Remem­
ber, if the battery is weak, the effective range
decreases.
If you need to replace the remote control, or if
you need to have it repaired, you must see
your authorized Audi dealer. Only then can
you use the key again.
@ Tips
- If the ignition is sw itched on, the remote
control system is deactivated.
- The remote control system can be affect­
ed by other systems operating in the
same frequency range close to the vehi­
cle, such as mobi le telephones, te levi­
s ion broadcasting stations, etc.

Electronic immobilizer
The immobilizer helps to prevent unauthor­
ized use of your vehicle .
A computer chip inside your key automat ica lly
deactivates the e lectronic immobilizer when
you insert the key in the ignition lock . When
you remove the key from the ignition lock, the e lectronic immobilizer is a utomatica lly acti­
vated once again.
@ Tips
- The vehicle cannot be started if an unau­
thorized key is used. The vehicle may not
start if another radio device such as a key
for another vehicle or transponder is lo­
cated on the key ring.

A WARNING
- Never use dayt ime running lights to see
where you are going. They are not bright
enough and w ill not let you see far
enough ahead for safety, especially at
dusk or when it is dark. Always switch on
the low beams at dusk or when it is dark.
- Automatic headlights are only intended
to assist the dr iver . They do not relieve
the driver of his responsibility to check
the headlights and to tu rn them on man­
ually according to the current light and
visibili ty cond itions. Fo r example, fog
and rain cannot be detected by the light
sensors . So a lways switch on the head­
lights under these weather cond itions
and when driving in the dark
io.
- Crashes can happen when yo u cannot see
the road ahead and when you cannot be seen by other motorists .
- Always turn on the headlights so that
you can see ahead and so tha t others
can see yo ur car from the bac k.
- With the switch in
AUTO front fog lights
ca nnot be t urned on in addition .
- The light sensor fo r headlight contro l is
l ocated in the rear view m irror mount .
Do no t apply any stickers to the w ind- shield in this area to prevent malfunc
­
tions or fa ilures.
- Some exter io r light ing funct ions can be
adjusted in the driver informat ion sys­
tem
~ page 2 7.
- If you remove the ignition from the igni ­
tion lock while the headlights are still
on, a buzzer will so und as long as the
dr iver's door is open to rem ind you to
turn off the lights.
- Always observe the specif ic loca l regula­
tions for your area as to when to use your
lights.
- With automatic headlights, the high­
beam funct ion is also available, but wit h
one restrict ion: If you have not switched
the high beams back to low beams dur­
ing automatic headlight operation (fo r
example, after d riving through a tunnel) ,
only the low beams come on the nex t
t ime au tomati c headlights are swi tc h ed
on. To use the high beams, you first have
to pull the high beam lever back and
then push the lever fo rward again.
- In cool or damp weather , the inside of
the headlights, turn signals and tail lights can fog over due to the tempera­
ture difference between the inside and
outside. They w ill clear shortly after
switching them on. This does not affect
the se rv ice life of the lighting .
- Frequent use of the coming home/leav ­
ing home function for app roach ing and
depa rting a vehicle parked in the da rk
w ill strain the battery . Thi s ap plies pa r­
tic ular ly if only short distances a re d riven
between stops . Occasionally drive longer
dis tances to make sure the battery is re ­
charged sufficiently.
