Electronic immobilizer
The immobilizer prevents your vehicle from
being start ed by unauthorized persons .
Inside the key there is a comp uter c hip. This
c hi p a utomat ically activates/deactivates the
electron ic immobilizer .
Applies to vehicles with ignition lock:
The electronic immobilize r deact ivates auto­
matically when yo u inse rt the remote contro l
key into the ignition lock . It activates again
automat ica lly when you remove the remote
control key from th e i gnition lock.
Applies to vehicles with convenience key:
If the remote control key is located inside the
vehicle and you press the
I S TA RT ENGINE STOPI button, the electro nic
i mmob ilizer deactivates automat ica lly. If you
switch the ig nition off and remove the remote
IJ,,

control key from the vehicle, the electronic
immobilizer activates again automatically.
.&_ WARNING -
Always take the key with you when you leave the vehicle. The key can disarm the
electronic engine immobilizer and permit
an unauthorized person to start the engine
and enable operat ion of the vehicle sys­
tems such as power window or power sun­
roo f leading to ser ious personal inju ry.
@ 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
fo r another vehicle o r a transpo nder is
l oca ted on the key r ing.

- Afte r closing the rear lid, always pull up
on it to make sure that it is p roperly
closed. Othe rwise it could ope n suddenly
when the vehicle is moving.
- To help pr eve nt poisono us exhaust gas
from be ing drawn into t he vehicle, al­
ways keep the rear lid closed wh ile driv­
ing . Never tra nsp o rt objects larger than
those which fit complete ly into the lug­
gage area, beca use the n the rear lid can­
not be f ully closed.
- Never leave your vehicle unattended es­
pecia lly with the rear lid left open. A
chi ld cou ld craw l into the car through the
luggage compartment and pu ll the lid
shut, becoming trapped a nd unable to
get out. To reduce the risk of personal i n­
jury, never let children play in or a round
your veh icle. Always keep the rea r lid as
well as the vehi cle doors closed when not
in use.
- A lways ensure that no one is wi thin
range of the re ar lid when it is moving, in
particular close to the hinges - fingers or
hands can be pinched .

Replacing wheels /tire s
Vehicles w ith all-wheel drive mus t always
h ave tires o f the same size. Also avoid t ires
with different tread depths. For details see
page
c::> page 206, New tires and replacing
tires and wheels.
A WARNING
Always adjust your driving to road and traf­
fic condit ions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks.
- Although the all-wheel dr ive is very ef­
fective, always remember that braking capacity is limited by t ire traction . You
should therefore not dr ive at excess ive
speeds on icy or slippery road surfaces.
- On wet road surfaces, be careful not to
dr ive too fast because the front wheels
c ou ld beg in to s lide on top of the water
(aquaplaning). If this sho uld oc cur, you
will have no warning from a sudden in­ crease in engine speed as with a front­
wheel drive vehicle. A lways drive at
speeds which are suited to the road con ­
ditions -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 period of time , the bat­
tery is discharged by idling cu rrent consumers
(e.g. immobilizer). In ce rtain c ircumstances it
can result in there being insufficient energy
M avai lab le to start the engine . N

Intelligent energy management in your veh i­
cle handles the d istribution of elec trical ener­
gy . Starting abi lity is markedly improved and
the life of the battery is extended .
Intellig ent technolog y 159
Basica lly, energy management consists of
b att ery diag nosis , id lin g cur rent man age­
ment
and dyn amic en ergy m anag ement.
Batte ry diagnosis
Battery diagnosis continuously determines
the state of the battery . Sensors determine
battery voltage, battery current and battery
temperature . This determines the current
state of charge and the power of the batte ry .
Idlin g current manag ement
Id ling current management reduces energy
consumption while the vehicle is standing.
With the ig nition switched off, it controls the
energy supply to the various electrical compo­ nents. Data from battery diagnosis is cons id­
ered.
Depending on the battery's state of charge ,
individual consumers are gradually turned off
to prevent excessive discharge of the batte ry
and thus maintain starting capability .
Dynamic energy manag ement
While the vehicle is being driven, dynamic en­
ergy management distributes the energy gen ­
erated according to the needs of the individ u­
al components . It regulates 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
limited.
- If start ing ability is threatened, the indi­
cator light (•) ;ippears

What you should know
The highest priority is given to maintaining
starting capability .
The battery is severe ly taxed in short-distance
driving , in ci ty traff ic and during the cold time
of year . Abundant electrical energy is .,.

240 Consumer Information
Technical Modifications
Our guidelines must be complied with when technical modifications are made .
Always consult an authorized Audi dealer be­
fore starting work on any modifications.
This will help ensure that vehicle function,
performance and safety are not impaired
¢ &. .
Attempting to work on electronic components
and the software used with them can cause
malfunctions. Because of the way electronic
components are interconnected with each
other, such malfunctions can also have an ad­
verse affect on other systems that are not di­
rectly involved. This means that you risk both
a substantial reduction in the operational
safety of your vehicle and an increased wear of
ve hicle parts ¢
A:,..
Author ized Audi dealers will perform th is
wo rk in a professiona l and competent manner
or, in special cases, refer you to a professional
company that specializes in such modifica­
tions .
A WARNING
Improper repairs and modifications can
change the way vehicle systems work and
cause damage to the veh icle and serious
personal injury.
-
If emergency repairs must be performed
elsewhere, have the vehicle examined by
an authorized Audi dealer as soon as possi­
ble.
