Engine does not switch off
Before and during each stop phase, the system
checks if certain conditions have been met . For
examp le, the engine will not switch off in the fol­
lowing situations:
- The engine has not reached the minimum re­
quired temperature for Start-Stop mode.
- The interior temperature selected by the A/C
system has not been reached.
- The outside temperature is extremely high/low.
- The windshield is being defrosted@.
- The parking system* is be switched on .
- The battery charge level is too low .
- The steering wheel is turned at a sharp angle or
is moving .
- After engaging the reverse gear.
- On sharp inclines.

play.
Engine automatically restarts
The standard Start-Stop mode will be canceled
during a stop phase in the following situations .
The engine restarts without any action by the driver.
Driving
- The vehicle rolls, for examp le while on a s lope.
- The interior temperature varies from the tem-
perature selected in the A/C system.
- The windshield is being defrosted@.
- The brake pedal is pressed severa l times in a
row.
- The battery charge level becomes too low.
- High power consumption.
The engine can turn off again when the condi­ tions for Start-Stop mode are met.
Ignition is switched off automatically
To prevent the battery from draining, the igni­
tion
will switch off automatically under the fol­
lowing conditions:
- The vehicle has already been driven.
- The Start-Stop-System has stopped the engine.
- The driver's door is opened .
- The driver's safety belt is removed.
- The brake pedal is not pressed down.
- The vehicle is stationary.
In this case, the activated low beam is replaced
by the parking light. The parking lights will
switch off after approximately 30 minutes or
when you lock the vehicle.
If the Start-Stop-System has not turned off the
engine or if you have switched the Start-Stop­
System off manually, the ignition will not be au­
tomatically switched off and the engine will con­
tinue to run

& WARNING
Improp er operat ion of the rear spoiler can
cause crushing injuries.
- Always make sure that nobody, espec ially
children , is in the way when the rea r spo ile r
i s deployed or retracted.
@ Note
- Neve r push on the vehicle on the rear spoi l­
er. Th is co uld cause damage .
- To prevent damage to the rear spoiler do
not lean or p lace anyth ing on it.
- Only ope rate the rear spoi ler manually when
the luggage compartment lid is close and
the rear spo iler moving parts are not
blocked . Ot herwise, damage could occur.
(D Tips
Clean the rear spoiler compartment every 2 to
3 mont hs. To function correct ly, the rear
sp oiler must be free of ice, sn ow and leav es.
Energy management
The starting ability is optimized
The energy management system manages the
ele ctrical energy distribu tion and op timi zes the
availability of elec trical energy for starting the
engine .
Whe n a ve hicle wit h a co nven tional e nergy sys ­
tem is not dr iven for a long time, the ba tte ry is
d rained by equipmen t (fo r example the immobil ­
izer). In certa in circ umstances, there cou ld may
not be eno ugh energy to start the engine .
Your veh icle i s equ ipped w ith an intellige nt ener ­
gy managemen t system for distr ibuting electr ic i­
ty . Th is significantly improves the starti ng ability
a nd increases the battery life .
T he energy m anagemen t sys tem Is made up of
battery diagno sis, idling current management
and dynamic energy management.
Battery diagnosis
T he batte ry diagnos is determines the ba tte ry
ch arge leve l. The sen sors de te ct the ba tte ry, the
194
batte ry current, an d the batte ry tempera ture.
The c urrent charge leve l and the perfo rmance of
t h e battery are determined based on th is.
Idling current management
The idling cur ren t management decr eases the
energy used wh ile pa rke d. Wi th the eng ine
switched off, it manages the energy dis trib ution
to t he d ifferent e lectr ica l components . Date from
battery diagnos is is ta ken into acco unt for this .
Depend ing on the batte ry charge leve l, elec trical
equipmen t is switched off one item afte r th e o th ­
e r, to prevent the battery from dra ining and to
r etain the starting ability.
Dynamic energy management
While driv ing , d ynam ic ene rgy man agement dis ­
t ribu tes the ap propri ate amount of energy to the
e lectrica l equ ipment. It controls the battery
c h arge level so t hat more ene rgy is not use d then
i s be ing generated in order to maintain an opti­
mal battery charge level.
(D Tips
- Energy management can not overcome the
laws of p hys ics. Note that the charge level
and length of the battery life a re limited.
- W he n the sta rting ability is endange red, the
(•j indicator light t urns on¢ page 16 .
What you should know
Maintaining the starting ability is the highest
priority .
A lot of st ress is placed on the ba ttery when dr iv ­
i ng sho rt distances, in t raff ic, and at cold t imes
of the year . A lot of ene rgy is used but little is
generated .
It is also critical when the engine is
not ru nning but e lectr ica l equipment is sw itched
o n. In th is case, energy is used but none is gener ­
ated.
In sit uat ions like this, energy ma nagement w ill
active ly regu lated the distribution of energy.
Long periods without use
If you do not drive yo ur vehicle for several days or
weeks, e lectr ica l equipment is grad ually scaled ..,.

back or switched off. This reduces energy use and
ensures the vehicle will be able to start after long
periods of time . Some convenience functions,
such as interior lighting or power seat adjust­ ment, may not be available under certa in circum­
stances . These convenience functions will be
available aga in once you switch the ignition on
and start the engine.
With the engine switched off
The battery will drain if you use functions such as
listening to the rad io while the engine is switched
off.
The vehicle's ability to start may be impaired by
the energy use, a message w ill appear in the In­
fotainment system d isp lay.
The message indicates that the system will
switch off automatically soon. If you would like
to continue using the funct ions, you must start
the eng ine.
With the engine running
Although electrical energy is generated whi le
driving, the battery can drain. This can happen
when little energy is generated, and much is used
and the charge level of the battery is not optimal.
To restore the balance of energy, components
that require large amounts of energy are tempo­
rarily sca led back or switched off . Heating sys­
tems in particu lar require a great deal of energy .
If you notice, for example, that the seat heating*
or rear window defroster is not working, then it
has been tempo rar ily reduced or sw itched off .
These systems are available again as soon as the
ene rgy balance has been restored.
In addition, you may notice that the idle speed
h as slightly increased . That is normal and no
cause for concern. Due to the increased idling
speed , the additional required energy w ill be gen ­
e rat ed and the battery will be charged.

Placing your vehicle out
of service
If you wou ld like to take your veh icle out of serv­
ice for a longer t ime, contact your authorized
Aud i dealer or authorized Aud i Service Facility.
They will advise you of important measures, such
as corrosion protection, maintenance and storage p rocedures . Also follow the informat ion about

Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels .
Fuel economy, environmental impact, and wear
on your engine, brakes and t ires largely depend
on three factors:
-your personal dr iv ing style
- operating conditions
198
- technical limitat ions
If you ant ic ipate what you need to do next and
drive econom ic a lly, you can easily cut yo ur fu el
consump tion by 10-15 percent. This section will
give you some tips on how you can he lp the envi­
ronment and your pocketbook .
(D Tips
'
The cons ump tion es tima tes as published by
EN VIRON MENTAL PRO TEC TION AGENCY ( EPA)
and T ransport Canada may not correspond to
your actual consumption on the road, which
will vary depending upon vehicle load and
speed, road and weather conditions, tr ip
l ength, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
.. Avo id unnecessary accelerating and brak ing.
Vehicles use the mos t fue l when they a re acceler ­
ating. I f yo u anticipate what is going to happen
next, you w ill need to b rake less and, thus, accel­
erate less. Let the veh icle coast whenever possi­
ble -for example when you see that the next traf­
fic light is red .
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage.
.. Try and keep well below your car's maximum
speed.
Acce lerating gently red uces fue l cons umption,
engine wear, and does not disturb the environ­
ment .
Fuel consumpt ion, exhaust emiss ions and engine
noise increase d isproportionately at high speeds .
If you drive at approximate ly three quarte rs of
top speed, fue l consumption will be reduced by
one half. Never drive faster than the posted
speed l imit and weather cond itions permit.

Checking and F ill in g
Battery
General information
Under no rmal operating conditions, the battery
in your Audi does not need any ma intenance.
W ith
high outside temperatu res or long daily
d rives we recommend that you have the electro­
lyte level checked by a service facility . The elec­
trolyte level should a lso be checked each time
the battery is charged ¢
page 230.
Have the bat tery checked when you take yo ur ve­
hicle in for service . You are we ll advised to re­
p lace a battery that is o lder than 5 years .
W ith certa in types of airbag deploymen t, the bat­
tery is disconnected from the vehicle electrica l
system for safety reasons ¢
.&. in Repair, core
and disposal of the airbags on page 158.
Disconn ecting the battery t erminal s
Some veh icle funct ions (power window regula­
tors, for examp le) are lost if the battery termi ­
na ls are disconnected. These functions have to be
re learned after the battery terminals are con­
nected aga in. To prevent this, the battery shou ld
only be disconnected from the vehicle electrical
system when absolutely necessary for repairs.
Vehicl es not driven fo r long period s
If you do not drive your vehicle over a period of
several days or weeks, e lectrica l components are
gradually cut back or switched off. This reduces
energy consumption and maintains starting ca­ pability over a longer period¢
page 194. Some
of the convenience funct ions may not operate,
such as the inter ior lights or power seat adjust­
ment. The convenience functions will be ava ilab le
again whe n you swit ch on the igni tion and sta rt
the engine.
Winte r operation
During the winter months, battery capacity tends
to decrease as temperatures drop . This is because
mo re power is also consumed w hile starting, and
the head lights, rear w indow defogger, etc ., are
used more often.
Avoid unnecessary power consumption, part icu­
larly in city traffic or when traveling only short
228
distances. Let your authorized Audi dealer check
the capacity of the vehicle battery before winter
sets in
¢ page 230 . A well charged battery will
not only prevent starting problems when the
weather is cold, but will also last longer.
(D Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the ve­
hicle battery should be removed and stored
where it will not freeze . This will prevent it
from being damaged and having to be re­
placed.
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart­
ment under the floor . Before you check anything
i n the luggage compartment,
