than is being generated and ensures an optimal state of charge for the battery.
@ Tips
- But even energy management cannot
negate the limits o f physics. Consider
that the power and life of a battery are
limited.
- If starting ability is threatened, you are
i nformed by a warning
¢ page 151,
Driver notification in the instrument
cluster display.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the co ld time
of year. Abundant e lectrical energy is re
quired, but only a litt le is generated. It is also
cr itical if the engine is not runn ing and electri
cal components are turned on. In th is in
stance energy is being consumed but none is
be ing gene rated.
It is in precisely these situations that you w ill
notice energy management actively regulat
in g the distribution of energy .
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks, electrical compo
nents are gradually cut back or switched off.
This reduces energy consumption and main
tains sta rting capab ility over a longer per iod.
Take into consideration that when you unlock
your veh icle, some convenience functions,
such as the remote key or power seat adjust
ment, may not be available . The convenience
functions will be ava ilable again whe n you
turn on the igni tion and star t the eng ine.
With the engine turned off
If you listen to the radio, for example, with
the eng ine turned off, the battery is being dis
charged .
Intellig ent technolog y 151
If starting capability is jeopardized d ue to en
ergy consumption, a message appears in the
drive r information d isplay .
You have to start t he engine to charge the
batte ry .
With the engine running
Although electrical energy is generated when
the ve hicl e is being driven, t he battery can be
come disc harged. This happens mostly when
li ttle energy is being generated and a great
deal consumed and the battery's state of
c h arge is not optimal.
T o b ring the energy ba lance back into equili
br ium, consumers which requ ire espec ially
large amounts of energy are temporari ly cut
back or switched off . Heating systems in pa r
ticu lar require a great deal of energy. If you
notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been temporarily cut back or switched
off . These systems w ill be available again as
soon as the ene rgy balance has been restored.
You w ill also notice that engine id le speed has
been increased slightly . Th is is normal and not
a cause for concern . By increas ing engi ne idle
speed the additional energy required is gene r
ated and the battery 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, this
is shown in the instrument cluster display
with the following driver message:
(•) Low battery charge: battery will be
charged while driving
T his not ificat ion reminds yo u that the start ing
capability of the engine may be limited . As
soon as you sta rt driving again, the battery
will be recharged and the not ificat ion w ill go
out. •

152 Intelligent technology
Driver notification appears and goes out
again
If t his driver notification a ppears after the ig
n ition 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
ni tion is turned on or while dr iv ing and does

as po ssible by an aut hor ized Audi dealer or
qualif ied wor kshop.

• Never put too much motor oil in your engine
¢ page 180, Adding engine oil
The cata lytic converter is an efficient "clean
up" device built into the exhaust system of
the vehicle. The catalytic converter burns
many of the pollutants in the exhaust gas be
fore they are released into the atmosphere.
The exclusive use of unleaded fue l is critically
important for the life of the cata lytic convert
er and proper functioning of the engine.
A WARNING
- Do not park or operate the veh icle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel sp ill or other material which can
cause a fi re.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold, exhaust p ipes, catalytic con
verte r o r heat shie lds . D uring d riving, the
substance used for undercoating cou ld
overheat and cause a fire.
([) Note
- Be aware that just one tank f illing with
le aded fuel will already seriously de
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil leve l
¢page 180 .
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis
fire. Unburned f uel could a lso get into
the exhaust system and this could cause
the catalytic converter to overheat.
- Do not turn
off the ignition while the ve
hicle is moving .
- Do not continue to operate your vehicle
under these conditions, as otherwise fuel
can reach the catalytic converter. This
could result in overheat ing of the con
verter, requ iring its replacement.
- To assure efficient operation of the Emis sion Control System: -
Have your vehicle maintained properly
and in accordance with the service rec
ommendat ions in yo ur Warranty
&
Maintenance book let.
- Lack of proper maintenance as we ll as
improper use of the vehicle will impair
the function of the emission contro l
system and could lead to damage.
@ For the sake of the env ironment
Even when the Emission Control System is
operating proper ly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operat ing states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or fil ling the tank with lead-free super
grade gasoline.
Shutting down vehicle
If you would like your vehicle to remain inop
erative for a longer per iod of t ime, contact an
Audi or othe r specialized dealer. They can ad
vise you on necessary precautions e.g . corro
sion prevention, maintenance and storage.
Pay attention to additional informat ion con
cerning the battery. Refer to<=>
page 184.
Operation and
maintenance
Fuel economy, env ironmental impact, and
wear on your eng ine, brakes and tires largely
depend on three facto rs:
-your personal driving style
- operating conditions
- technical limitat ions
By having your veh icle regu larly se rviced by an
authorized Audi dea ler helps to ensure that it
runs properly and economica lly. The condition
of your vehicle not only affects its safety and ability to hold its va lue, it also affects
fu el
cons umpt ion.
The amount of oi l used is re lated to engine
l oad and speed.

Battery
General information
Your vehicle is equipped with a specia l bat
te ry, an
ACM battery. This ba tte ry is located
i n the luggage compartmen t an d must be re
placed with an origina l equipment battery .
U nder normal operating conditions, the bat
tery is
maintenance -free.
Have the batte ry checked when yo u take your
vehicle in for service. You are well advised to
replace a battery that is o lde r than 5 years.
Disconnecting the battery te rminals
Some vehicle fu nctions (power window reg u
lators, for ex ample) are lost if the batte ry te r
mina ls are disconnected. These f unctions have
to be relearned after the battery termina ls are
connected again. To prevent this, the battery
sho uld only be disconnected from the veh icle
electrical system when abso lutely necessary
for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period
of seve ral days or weeks , e lectrica l compo
nents are gradually cut back or switched off.
This reduces energy consumption and ma in
ta ins start ing capability over a longer period
