[ i J Tips
• The digital c lock 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 !CHECK] button~

eter.
• USA models - Miles
• Canada models -Kilometers
You can switch the disp lay from miles to kilometers and vice versa
via the MMI.

Upper odometer (trip odometer)
The upper odometer shows the total number of miles (kilometers)
driven since you last reset the odometer to zero. You can use this
odometer when you want to keep track of how many miles (kilome ­
ters) you have driven for a single trip or errand. The last digit indi­
cates 1/10 of a mile (100 meters).
You can reset the trip odometer to zero by pressing the Reset button
~ o.o.
Malfunction message

dEF
wil l appear in the trip odometer and will stay on . Contact your
authorized Audi dealer to have the problem corrected .

When the ignition is switched on, the data on the ignition key are
scanned automatically.
If an unauthorized key was used,
SAFE is displayed continuously in
the odometer display field. The vehicle cannot be operated

Vehicle care I I Technical data

[ i] Tips
The replacement battery must 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 elec ­
tronic immobilizer when you insert the key in the ignition lock, or on
vehicles with Advanced Key *, when the key is inside the vehicle.
When you remove the key from the ignition lock, or on vehicles with
Advanced Key, when you remove the key from the vehicle, the elec ­
tronic immobilizer is automatically activated once again .
If an unauthorized key was used , SAFE is displayed continuously in
the odometer display field.
& WARNING
Always take the key with you when you leave the vehicle. The key
can disarm the electronic engine immobilizer and permit an unau­
thorized person to start the engine and enable operation of the
vehicle systems such as power window or power sunroof* leading
to serious personal injury.
[ i] Tips
• Your engine can only be started using the factory -equipped key.
• You may no t be able to start your vehicle if an ignition key of a
different vehicle make is also located on your set of keys. •
Controls and equip ­
ment
Opening and closing
Valet key function
The valet key function prevents unauthorized persons

valet key function
Activating and deactivating the function
Insert the master key into the ignition lock and switch on
the ignition.
Press the [VALET) button~ fig. 33 to activate/ deactivate
the function as desired. The indicator light in the button
illuminates when the function is active.
- Remove the master key from the ignition lock.
Hand over only the
valet key~ page 48, fig. 29 to the
person who will take charge of the vehicle.
When the function is switched on, the buttons for opening the rear
lid and glove compartment have no function . However, please note

still open the glove compartment .
As long as the ignition is switched off, you can still open the rear lid
using the rear lid button on the master key

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 -

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 266, "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.
