power management
While the vehicle is moving, this function distrib­
utes the available power to the various electrical
components and systems according to their re­
quirements. The power management ensures
that on-board systems do not consume more
electrical power than the alternator can supply,
and thus maintains the maximum possible bat­
tery power Level.
ijJ Note
- The power management system is not able
to overcome the given physical Limits.
Please remember that the power and Life of
the battery are Limited.
- If the indicator Lamp ril c:> page 13 appears,
the starting ability may be impaired.
Points to remember
Starting ability has first priority.
Short trips, city traffic and Low temperatures all
place a heavy Load on the battery . In these condi­
tions a Large amount of power is consumed, but
only a small amount is supplied. The situation is
also critical if electrical equipment is in use when
the engine is not running. In this case power is
consumed when none is being generated.
In these situations you will be aware that the
power management system is intervening to con­
trol the distribution of electrical power.
When the vehicle is parked for long periods
If you do not drive your vehicle for a period of
several days or weeks, the power management
will gradually shut off the on-board systems one
by one, or reduce the amount of current they are
using. This Limits the amount of power consumed
and helps to ensure reliable starting even after a
Long period. Certain convenience features, such
as remote control unlocking, may not be availa­
ble. These functions will be restored when you
switch on the ignition and start the engine. Intelligent
technology
With the engine switched off
If you Listen to the radio or use other electrical
equipment when the engine is not running, this
will discharge the battery.
A message will appear on the infotainment dis­
play before the battery power drops to a Level
where the starting ability is impaired.
This message warns you that the system you are
using will soon be switched off automatically.
You should therefore start the engine if you wish
to continue using the system.
When the engine is running
Although the alternator generates electrical pow­
er, the battery can still become discharged while
the vehicle is being driven. This can occur when a
Lot of power is being consumed but only a small
amount supplied, especially if the battery is not
fully charged initially.
To restore the necessary energy balance, the sys­
tem will then temporarily shut off the electrical
components that are using a Lot of power, or re­
duce the current they are consuming. Heating
systems in particular use a Large amount of elec­
trical power. If you notice, for instance, that the
seat heating* or the rear window heater is not
working, they may have been temporarily switch­
ed off or regulated to a Lower heat output. These
systems will be available again as soon as suffi­
cient electrical power is available.
You may also notice that the engine runs at a
slightly faster idling speed. This is quite normal,
and no cause for concern. The increased idling
speed allows the alternator to meet the greater
power requirement and charge the battery at the
same time.
Information saved in the
control units
The vehicle is fitted in the factory with electronic
control units that, among other things, control
the engine and the gearbox. The control units al­
so monitor the exhaust system and the airbags.
The control units continually analyse data rele-
vant to the vehicle while you are driving. In the

technology
event of faults or anomalies in the vehicle data,
only these data are saved. As a rule, faults are
shown by the warning lamps in the instrument
cluster.
Data saved in the control units can only be read
and analysed with special equipment.
A qualified workshop is only able to recognise
and deal with faults by using the relevant saved
data. Among other things, the saved data may
contain the following information:
- Data relating to the engine and the gearbox
-Speed
- Dire ction of travel
- Braking force
- Seat belt warning system data
The control
units
installed will not under any cir­
cumstances record conversations in the vehicle.
On vehicles with an automatic SOS dial system
via a mobile phone or another connected device,
the current location of the vehicle can be trans­
mitted. In accidents where the control units reg­
ister that airbags have been triggered, a signal
can automatically be sent by the system. This de­
pends on the service provider. The signal can only
be sent in areas with sufficient mobile phone cov­
erage.
Event data recorder
Your vehicle is not equipped with an event data
recorder.
In an event data recorder, information about the
vehicle is temporarily saved. In the event of an
accident, you can therefore obtain detailed infor­
mation about the course of events. On vehicles
with an airbag system, accident-related data such
as impact speed, seat belt status, seat positions
and trigger times can be saved. The exact infor­
mation saved depends on the manufacturer.
The installation of an event data recorder is sub­
ject to the agreement of the vehicle's owner. This
process is governed by legislation in some coun­
tries.
108 Reprogram
ming control units
All data for controlling components are saved in
the control units. Some convenience features,
such as one-touch signalling, single door unlock­
ing and display messages can be reprogrammed
using special workshop equipment. If any con­
venience features are reprogrammed, the infor­
mation in this Owner's Manual will no longer be
accurate for the features that have been
changed. We recommend having the reprogram­
ming confirmed by an Audi workshop in the
"Workshop remarks" section of your Service
Schedule.
Your Audi dealer will be able to provide you with
information about possible reprogramming op­
tions.
Event memory
There is a diagnostic connection for reading out
the event memory located in the footwell on the
driver's side of the vehicle. Information regarding
the operation and status of the vehicle's elec­
tronic control units is stored in the event memo­
ry. The event memory should only be read out
and erased by a qualified workshop.
A WARNING
The diagnostic connection must not be used
for other purposes. Incorrect use can cause
malfunctions -risk of accident!

away from batteries: the gases given off can
cause an explosion.
- If jump-starting another vehicle, position
the jump Leads in such a way that they can­
not come into contact with any moving
parts in the engine compartment of the oth­
er vehicle.
CD CAUTION
Please note that the above method of con­
necting the Leads is intended for jump-start­
ing your vehicle. If jump-starting another ve­
hicle, you should not connect the negative
lead (-) to the negative terminal of the dis­
charged battery, but directly to the engine
block or a solid metal part bolted to the en­
gin e block. If the battery of the other vehicle
does not have a gas vent, there is a risk that a
mixture of oxygen and hydrogen gas can accu­
mulate and cause an explosion.
@ Note
- The battery is vented to the outside to pre­
vent gases entering the vehicle's interior.
- Connect the battery clamps so they have
good metal-to-metal contact with the bat­
tery terminals.
Tow-starting / towing
away
General notes
Some experience is required to tow or tow-start a
vehicle, especially when using a tow-rope. Both
drivers should be familiar with the technique re­
quired for towing. Inexperienced drivers should
not attempt to tow-start or tow away another ve­
hicle.
Do not pull too hard with the towing vehicle and
take care to avoid jerking the tow-rope. When
towing off-road, there is always a risk that the
anchorage points may be overloaded.
Tow-bar / tow-rope
It is easier and safer to tow the vehicle with a
tow-bar. You should only use a tow-rope if you do
250 not
have a tow-bar. It is advisable to use a tow­
rope made of elastic synthetic fibre or similarly
elastic material.
Notes on towing vehicles
The vehicle can be towed with a tow-bar or tow­
rope. When the engine is not running, the gear­
box will not be adequately Lubricated if the fol­
lowing speed/distance restrictions are not ob­
served:
- The vehicle must not be towed faster than
SO km/h.
- The vehicle must not be towed further than
50km.
Additi onal notes on towing by breakdown
truck
If one of the axles has to be raised in order to tow
the vehicle, please refer to the following table to
determine the appropriate axle for your gearbox/
drive combination:
Front-wheel IFour-wheel
drive drive
Manual Front
or rear Front or rear
gearbox axle

Automatic gearbox Front
axle Front axle
Four-wheel drive: If the vehicle is to be towed
with one of the axles raised, the ignition must be
switched off; otherwise the drive train can be
damaged.
Notes on tow-starting
Automatic gearbox: For technical reasons, your
vehicle must not be tow-started.
Manual gearbox: As a general rule, tow-starting
is not recommended. If the engine will not start,
it is best to try starting it using the battery of an­
other vehicle ¢ page 248 before attempting to
tow start. If this is not possible, you can try to
push-star t or tow-start the vehicle ¢ page 251,
