The anti-theft alarm system triggers an audi­
b le alarm and turns on the emergency flasher
if an unauthor ized interference with the vehi­
cle is sensed by the system.
How is the anti-theft alarm system
switched on?
T he anti -theft a larm system is switched on
when you lock the driver's door manually us­
ing the fold-out key, or when you use the re­
mote control. The system is activated approxi­
mately 30 seconds after the veh icle is locked .
The indicator light ~
fig. 36 starts flashing
rapidly for 30 seconds and then blinks slowly.
How is the anti-theft alarm system
switched off?
The anti-theft a larm system is switched off
on ly when you use the remote contro l to un­
lock your veh icle. If you do not open a door
within 30 seconds after you have un locked
with the remote cont ro l, the vehicle will lock
itself again automatically.
If you lock just the dr iver's doo r using your
key, the front passenger's door and the rear
lid remain locked.
When will the anti theft alarm system be
triggered?
When the vehicle is locked , the alarm system
monitors and protects the following pa rts of
the vehicle:
- engine compa rtment
- luggage compartment
- doors
- ignition
When the system is activated, the alarm will be triggered if one of the doors, the engine
hood or the rear lid are opened, or if the igni­
tion is turned on.
The anti-theft a larm system will also go off
when the battery is disconnected.
You can also trigge r the alarm by pressing the
PANIC button on your remote-control key.
This will a lert other peop le in case of emer-
Opening and closing 39
gency. Press the PANIC button again to turn
off the alarm .
How is the anti-theft alarm switched off
when trigge red?
The alarm system is switched off when you
unlock the vehicle using the remote -control
key or when the ignition is switched on . T he
alarm will also switch itself off when it comes
to the end of its cycle .
Emergency flasher
The emergency flasher will blink briefly when
the doors, engine hood and rear lid a re prop­
erly closed.
If the emergency flashers do not blink, check
the doors, engine hood and rear lid to make
sure they are properly closed. If you close a
door, the hood or the rear lid with the anti ­
theft alarm sw itched on, the emergency flash­
ers will blink only after you have closed the
door or lid .
(!) Tips
For the anti-theft alarm system to func­
tion properly, make sure all veh icle doors
and windows are closed before leaving the
vehicle.

interior lights are turned off.
When a door is open, the interior lights are
turned off after about 10 minutes to prevent battery dra ining.

you leave your veh icle . This makes a vehicle
theft even more difficult ¢ .&. .
Ignition ke y saf ety lock
After swi tching off the ignition, the ig nit ion
key can on ly be removed from the ign it ion
lock when the se lector lever is in the "P"
(Park) position . After you have removed the
key, the selector lever is locked and cannot be
moved.
Ignition on @
If it is diffic ult to turn the key after you have
inserted it into the ignition lock, turn the
steering wheel back and forth. This will take
the load
off the steering lock mechanism and
you will be able to turn the key freely and
start the engine.
Starting the engine @
In this position the engine starts . While the
engine is starting, the power supply to the headlights and other e lectrica l consumers is
temporari ly interrupted to conserve battery
power. After the engine has started, release
the key and it will return to posit ion
(D .
Before the starter can be operated again the
key must be turned back to position @. The
non -repeat loc k prevents you from damaging
the starter when the engine is runn ing .
A WARNING
-Never remove the key from the ign ition
lock whi le the vehicle is moving. The
steeri ng wheel will lock causing loss of
c ontrol.
- If you have to leave your vehicle -even
for just a m inute -always remove t he ig­
nition key and take it with you. This is es­
pecially important if you a re going to
leave ch ildren behind in the vehicle. The
children co uld start the engine or use
other vehicle controls. Unsupervised use
of vehicle controls (for examp le, power
windows) can cause serious personal in­
jur ies .
(!) Tips
If the vehicle battery has been disconnect­
ed and then reconnected, then you must
l eave the key in position
(D for about 5
seconds before you can start the engine.
Starting and stopping
the engine
Starting the engine
The engine can only be started with an origi­
nal Audi key.
.,. Set the park ing brake.
.,. Move the se lector lever to the neutral posi ­
tion (automatic transmission): selector lever
in
P or N) ¢ .&_ .
.,. On vehicles with manua l transmission, fully
depress the clutch pedal.
.,. Turn the ignition key to pos it ion @
¢ page 71, fig . 71 -do not depress the gas
pedal when starting the engine!
.,. Let go of the key as soon as the engine
starts.
A cold engine may at first be loud after it has
been sta rted. This is due to the hydrau lic
valves bu ild ing up the oil pressure. This nor­
mal and no need for co nce rn .
If the engine does not start immediately, stop
trying after 10 seconds and then try to restart
the engine abou t 30 seconds late r.
A WARNING
Neve r star t or let the eng ine run in a con­
f ined or enclosed area . Exhaust fumes
from the engine contain carbon monoxide,
a colorless and odor less gas . Ca rbon mon ­
oxide can be fatal if inhaled.
- Never leave the engine id ling unattend­
ed. An unattended veh icle w ith a runn ing
engine poses a danger of personal injury
or theft.

than is being generated and ensures an opti­mal state of charge for the battery.
@ Tips
- But even energy management cannot
negate the limits o f physics. Consider
that the power and life of a battery are
li mited.
- If starting ab ility is threatened, you are
i nformed by a warning
¢ page 157,
Driver notification in the instrument
cluster display.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the co ld time
of year. Abundant e lectrica l energy is re­
quired, but only a litt le is generated. It is also
cr itical if the engine is not run ning and electri­
cal components are turned on. In th is in­
stance energy is being consumed but non e is
be ing gene rated.
It is in precisely these situations that you w ill
notice energy management actively regulat ­
in g the distribution of energy .
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and mai n­
tains sta rting capab ility over a longer per iod.
Take into consideration that when you un lock
your ve hicle, some co nvenience functions,
such as the remote key or power seat adjust ­
ment, may not be available . The convenience
f u nctions w ill be ava ilable again whe n you
turn on the igni tion and star t the eng ine.
With the engine turned off
If you listen to the radio, for example, with
the eng ine turned off, the battery is being dis­
charged .
Intellig ent technolog y 157
If starting capability is jeo pardi zed d ue to en ­
ergy consumption, a message appears in the
drive r information d isplay .
You have to start t he engine to charge the
batte ry .
With the engine running
Although e lectrical energy is generated when
the ve hicl e is being driven, t he battery can be­
c ome disc harged. This happe ns mostly when
li ttle energy is being generated and a g reat
deal consumed and t he battery's sta te of
c h arge is not optimal.
T o b ring the energy b alance b ack into equili ­
br ium, consumers which requ ire espe cially
la rge amounts of energy a re temporari ly cut
back or switched off . Heating systems in pa r­
ticu lar require a great deal of energy. If yo u
notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been temporarily cut back or sw itched
off . These systems w ill be available again as
soon as the ene rgy balance has been restored.
You w ill also notice that engine id le speed has
been increased slightly . T hi s is normal and not
a cause for conce rn . By i ncreas ing eng ine id le
speed the additional energy r equired is gene r­
ated and the battery is charged.
Driver notification in the instrument
cluster display
If battery power drops into the range where it
can limit the ability of the engine to start, this
is shown in the instrument cluster display
with the following driver message:
(•) Low battery charge: battery will be
charged while driving
T his no tificat ion reminds yo u that the star ting
capability of the engine may be lim ited . As
soon as you sta rt dr iving again, the battery
will be recharged and the not ificat ion w ill go
out. •
