When will the anti theft ala rm system be
triggered?
When the vehicle is locked , the alarm system
monitors and protects the following parts of
the vehicle:
- engine compartment
- luggage compartment
- doo rs
- 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 ign i­
tion is turned on.
The anti-theft alarm system will also go off
when the battery is disconnected.
You can a lso trigger the alarm by pressing the
PANIC button on your remote-control key.
This will alert other people in case of emer­
gency. Press the
PANIC button again to turn
off the alarm .
How is the anti-theft alarm switched off
when triggered?
The alarm system is switched off when you
unlock the vehicle using the remote-control key or when the ignition is sw itched on . The
a larm will also switch itse lf 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 are 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 ant i­
theft alarm switched on, the emergency flash­
ers will blink only after you have closed the
door or lid.
(1) Tips
For the anti-theft alarm system to func­
tion properly, make sure all vehicle doors
and windows are closed before leaving the
vehicle.

~ page 72, fig. Bl -do not depress the gas
peda l 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 started. This is due to the hydraulic
valves bu ild ing up the oil pressure. Th is nor­
mal and no need for concern .
If the engine does not start immediately, stop
trying after 10 seconds and then try to restart
the engine about 30 seconds later.
A WARNING
-Never start or let the eng ine run in a con-
fined o r enclosed area . Exhaust fumes
from the engine co ntain carbon monoxide,
a colorless and odo rless gas. Ca rbon mon ­
oxide can be f atal if inhaled.

- Never modify t he front bumper or parts
of the veh icle body .
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­
ment upholstery ove r the front seat­
backs that have not been spec ifi cally
approved by A udi.
- Never use add itiona l seat cushions that
cover the areas whe re the side airbags
inflate .
- D amage to the o rigina l seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can be activated only once . Afte r an airbag has inf lated, it
must be replaced by an author ized Audi
dealer or qualified technic ian who has
the techn ica l information, tra ining and
special equipment necessary.
- The airbag system can be deployed only
once. After an a irbag has been deployed,
it must be replaced w ith new replace ­
ment parts designed and approved espe­
cially for your Aud i model version. Re­
placement of complete a irbag systems
or airbag componen ts must be per­
formed by qualified workshops only .

· Other things that can affect Advanced
Airbag performance
Chang ing the veh icle's suspens io n system can
change the way that the Advanced Airbag Sys­
tem perfo rms in a c rash. For examp le, using
t ir e- rim combinat ions not approved by A udi ,
lower ing the veh icle, c hanging the st iffness of
the suspens ion, including the spr ings, suspen­
sio n struts, shock absorbers etc . can change
the forces that ar e measured by the airbag
sensors and sent to the electronic contro l
unit. Some suspension changes can, for exam­
ple, increase the force levels measured by the
senso rs and make the airbag system deploy in
c rashes in which it wou ld no t deploy if the
c h anges had not been made. Other kinds of
c h anges may reduce the fo rce leve ls meas ­
u red by the sensors and p reven t the airbag
from dep loying when it should.
A WARNING
Changing the vehicle's suspension includ­
i ng use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
fo rmance and increase the r isk of serious
personal injury in a crash .
- Never install suspension components
that do not have the same performance characterist ics as the components origi ­
na lly installed on your vehicle .
- Never use tire-rim combinations that
have no t been approved by Audi.

146 Intellig ent technolog y
-If the power steering system should fail,
or if the eng ine is not running (for exam­
ple, while being towed), yo u wi ll st ill be
able to steer the veh icle. However, more
effort will be requ ired to do so .
- If the power steering system is not func­
tioning properly, contact your authorized
Audi dealer immediately .
Driving with your
quattro
App lies to vehicles: with all-wheel drive
With all-wheel drive, all four wheels are driv­
en.
General information
W ith all-whee l drive , power is distributed to
a ll four wheels . This happens automa tica lly
depending on your dr iv ing sty le and the road
conditions at the time. See also ~
page 141.
The all-wheel drive concept is designed for
high engine powe r. You r vehicle is exception­
ally powerful and has ex ce ll ent dr iving charac ­
teristics bot h under normal driving conditions
and on snow and ice. Always read and fo llow
safety precautions ¢
.&..
Winter ti re s
When dr iving in the w inte r, your ve hicle w ith
a ll-wheel d rive has an advantage, even with
regular tires . In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son tir es) for improv ed driveability and brak­
ing: these tires must be mounted on
a ll fo ur
wheels . See also ¢ page 195, Win ter tires.
Snow cha in s
Where tire chains are mandatory on certain roads, this normally a lso applies to vehicles
with a ll-wheel drive¢
page 196, Snow
chains.
Replacing whe els /t ires
Vehicles wit h all-wheel drive mus t always
have tires of the same size . Also avoid tires
with different tread depths. For details see page
q page 191, New tires and replacing
tires and wheels .
Off-Road driving ?
Your Aud i does no t have enough g round clear­
ance to be used as an off-road vehicle. It is
therefore bes t to avoid rough tracks and un­
even terrain as much as possib le . Also refer to
¢ page 150 .
A WARNING
-Always ad just your dr iv ing to road and traf-
f ic conditions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks.
- Although the all-wheel drive is very ef­
fective, always remember that braking capacity is lim ited by tire t raction . You
should therefore not d rive at excessive
speeds on icy or slippe ry road surfaces.
- On wet road surfaces, be careful not to
d rive too fast because the front whee ls
could begin to slide o n top of the water
(aquaplan ing). If th is should occur, yo u
will have no warning from a s udden in ­
crease in eng ine speed as wit h a front ­
wheel drive vehicle. Always drive at
speeds which are su ited to the road con­
d itions. -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting the engine.
If a vehicle with a conventional energy system
is not driven for a long per iod of t ime, the bat­
te ry is discharged by idling cur rent consume rs
(e .g. immobili zer) . In cert ain circumstances it
can resu lt in the re being insufficient energy
available to start the eng ine.
Intelligent energy management in you r vehi­
cle h andles the dis trib ution of e lectr ica l ene r­
gy. Start ing ability is ma rkedly improved and
the life of the battery is extended . .,._

Basically, energy management consists of
batter y di agno sis, idling cur rent man age­
ment
and d yn ami c en ergy m anagement.
Battery diagnosis
Battery d iagnosis continuously dete rmines
the state of the battery. Senso rs determ ine
battery vo ltage, battery current and battery
temperature. This determines the current
state of charge and the power of the battery.
Idling curre nt management
Idling c urrent management red uces energy
consumption while the vehicle is standing.
With the ignition switched off, it contro ls the
energy supply to the various electrica l compo­
nents . Data from battery diagnosis is consid­
ered.
Depending on the battery's state of charge,
individua l consumers are grad ually turned off
to prevent excess ive d ischarge of the battery
and thus mainta in start ing capability.
Dynam ic energ y manag em ent
While the vehicle is being driven, dynamic en ­
ergy management distributes the energy gen­
erated according to the needs of the individu­
a l components. It regu lates consumption, so
that more electrical energy is not being used
than is being generated and ensures an opti­
mal state of charge for the battery .
(D Tips
-But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are l imited.
- If starting ab ility is threatened, you are
i nformed by a warn ing
c!;> page 148,
Driver notification in the instrument
cluster display.
Int ellig ent technolog y 147
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driv ing, in city traff ic and during the cold time
of year . Abundant electrical energy is re ­
quired, but only a l ittle is generated .
It is also
c ritical if the engi ne is not running and electri­
ca l components are turned on . In this in­
stance ene rgy is be ing consumed but none is
being generated.
It i s in precise ly these situations that you will
notice ene rgy management act ive ly regu lat­
ing the d istribu tion of ene rgy.
V ehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks , e lectr ica l compo­
nents a re g radually cut back or switched off.
T his reduces energy consumption and ma in­
ta ins s tart ing capability over a longer pe riod .
Take into considerat ion that when you unlock
you r vehicle, some convenience functions,
s u ch as the remo te key o r power seat adjust­
ment, may not be available. The convenience
f unct ions wi ll be available again when you
turn on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for examp le, w ith
the engine tu rned o ff, the battery is being dis ­
charged .
If starting capabi lity is jeopardized due to en­
ergy consumption , a message appears in the
driver in formation d isplay.
You have to start t he engine to charge the
battery.
With the engine running
Although electrical energy is generated when
the vehicle is being driven, the battery can be­ come discharged . This happens mostly when
little energy is being gene rated and a great
deal consumed and the battery's state of
c h arge is not opt imal.
•
•

148 Intelligent technology
To bring the energy balance back into equili­brium, consumers which require especia lly
l arge amo unts of energy are temporari ly c ut
back or switched off. Heating systems in par­
ticular requ ire a great dea l of energy. If you
n otice, for example, that the heated seats * or
the heated rea r window a re not heating, they
have been temporar ily cut back o r switched
off. These sys tems will be ava ilable again as
soon as the energy ba lance has bee n restored.
You will also not ice that engine idle speed has
been inc reased slightly. This is no rma l and not
a cause fo r concern . By increas ing engine idle
spee d the add itiona l ene rgy required is gener ­
ated and the ba ttery 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, th is
i s shown in the instrument cluster display
with the following driver message:
(•) Low battery charge : battery will be
cha rged while dri ving
This notification reminds you that the starti ng
capability of the engine may be limited. As
soon as you start driving aga in, the battery
will be recharged and the notification will go
out .
Driv er notificat ion appears and goes out
again
If t his driver notification appears after the ig­
ni tion is turned on or while driv ing and it goes
out again after a while, the battery has been
adequately rec harged.
Driver notification appears and does not
go out again
If t his driver notification appears after the ig­
n ition is turn ed on or while driv ing and does
n ot go ou t aga in, t he battery's s tate of charge
is not i n the opt imal range. St arting ability is
restricte d. Have the bat tery checked as soon
as possible by a n authorized Audi dealer or
q ua lified workshop.
