2009 AUDI S6 immobilizer

Instruments and warning /indicator lights
[ i J Tips
• The digital clock and the odometer are turned on for about 30
seconds when the driver's door is opened.
• When the ignition is turned off, the odometer reading and the
digital clock with date display can be switched on for about
30 seconds by pressing the
I CHECK) button => page 15, fig. 5. •
Speedometer with odometer
The speedometer shows you the vehicle speed, and the
odometer shows you how many miles (kilometers) you
have driven.
Fig . 4 Instrument
c luster Odometer and
reset button
The odometer and trip odometer are located inside the speedom­
eter.
• USA models -Miles
• Canada models -Kilometers
You can switch the display from miles to kilometers and vice versa
via the MMI.
Lower odometer
The lower odometer shows the total number of miles (kilometers)
driven. Upper
odometer (trip odometer )
The upper odometer shows the total number of mil·es (kilometers)
driven since you last reset the odometer to zero. You can use this
odometer when you wan t to keep track of how many miles (kilome ­
ters) you have driven for a single trip or errand. The last d igit indi­
cates 1/10 of a mile (100 meters) .
You can reset the trip odometer to zero by pressing the Reset button

Malfunction message
If there is a malfunction somewhere in the instrument cluster,
dEF
wi ll appear in the trip odometer and will stay on. Contact your
authori zed Audi dealer to have the prob lem corrected .
Immobilizer
When the ignition is switched on, the data on the ignition key are scanned automatically.
If an unauthorized key was used,
SAFE is disp layed continuously in
the odometer display field . The vehicle cannot be operated

message
Please refuel. There are approximately between 1.8 and 2.4 .,_

Openin g a nd clo sin g
- Place the cover w ith the new battery on the key base and
press both parts together.
c£> For the sake of the environment
Dispose of dead batteries properly so as not to pollute the environ ­
men t.
[ i J Tip s
The replacement battery mus t be the same specification as the
original. •
Electronic immobilizer
The immobilizer helps to prevent unauthorized use of
your vehicle.
A computer chip inside your key automatically deactivates the e lec ­
tronic immobilizer when you inser t the key in the igni tion lock, or on
vehic les with Convenience key *, when the key is inside th e vehicle.
When you remove the key from the ignition lock , or on vehic les with
Conv enience key, when you r emove the key from the vehicl e, the
e lectronic immobil izer is automatically activated once again .
If an unau thorized key was used, SAFE is displayed continuous ly in
the odometer disp lay field .
& WARNING
Always take the key with you when you leave the vehicle . The key
ca n dis arm the el ectronic eng ine immobili zer and pe rm it an u nau­
thori zed per son to start the engine and enable op era tion of the
v ehi cle sys tem s such as po wer w ind ow or p ower s unroof* lead ing
to seriou s per son al injur y.

• Your engine can only be started using the factory -equipped key .
• You may not be able to start your vehicle if an ignition key of a
differen t vehicle make is also located on your set of keys.

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 period of time, the battery is discharged by idling current
consumers (e.g. immobilizer). In certain circumstances it can resu lt
in there being insufficient energy available to start the engine .
Intelligent energy management in your vehicle handles the distribu ­
tion of electrical energy . Starting ability is markedly improved and
the life of the battery is extended.
Basical ly, energy management consists of
battery di agn osis, idling
current mana gement
and dynami c en ergy management .
Batter y diagn osis
Battery diagnosis continuously deter min es the state of the battery.
Sensors determine battery vo ltage, battery current and battery
temperature . This determines the cu rrent state of charge and the
power of the battery .
Idling c urrent man ag em en t
Idling current management reduces energy consumption while the
vehicle is standing. With the ign it ion switched off, it controls the
energy supply to the various electrical components. Data from
battery diagnos is is considered .
Depending on the battery's state of charge, individual consumers
are gradually turned off to prevent excessive discharge of the
battery and thus maintain starting capability.
Dynamic energ y managem ent
While the vehic le is being driven, dynamic energy management
distributes the energy gene rated acco rding to the needs of the indi -
Controls and equip­
ment Safety first Vehicle operation
In
te llig ent tec hn olo gy
vidual components . It regulates consumption, so that more e lec­
trical energy is not being used than is being ge nerated and ensures
an optimal state of charge for the battery.
[ i ] Tips
• But even energy management cannot negate the limits of
physics. Consider that the power and life of a battery are limited .
• I f starting ability is threatened, you are informed by a warning
=> page 270, "Drive r notifica tion i n the instrument cluster
display" .•
What you should know
The highes t pri ority is given to main tain ing starting capa ­
bility.
The battery is severe ly taxed in short-distance driving, in city traffic
and during the co ld time of year. Abundant electrical energy is
required, but only a little is generated. It is also critical if the engine
is not running and elect rica l components are turned on. In this
instance energy is being consumed but none is being generated .
I t is in precisely these situations that you will notice energy manage ­
ment active ly regula ting the distr ibut ion of energy.
Vehicle stands fo r an extended period
If you do not drive your vehicle over a period of several days or
weeks, electrical components are gradually cut back or switched off.
This reduces energy consumption and maintains starting capability
over a longer period.
Take into considerat ion that when you un lock your veh icle, some
convenience functions, such as the remote key or power seat
adjustment, may not be availab le . T he conven ience functions will be
available again when you turn on the ignition and start the engine.
