Facility immediately to have the malfunction cor­
rected. The color of the indicator light depends
on the vehicle speed.
A WARNING
-
Driving at higher speeds without the rear
spoiler deployed can impair handling charac­ teristics, making the vehicle harder to con ­
trol.
- Always make sure that the spoiler is de­
ployed when driving at speeds over 85 mph
(140 km/h). If the rear spoiler warning/indi­
cator light in the instrument cluster comes
on, the rear spoiler may not have deployed.
- Never drive at speeds higher than 85 mph
(140 km/h) if the spoiler is not deployed .
Have the spoiler inspected as soon as possi­
ble by an authorized Audi dealer or qualified
workshop.
- Always obey speed limits and other traffic
laws.
A WARNING t =
Improper operation of the rear spoiler can
cause crushing injuries.
-
- Always make sure that nobody, especially
children, is in the way when the rear spoiler
is deployed or retracted.
(D Note
- Never push on the vehicle on the rear spoil­
er. This could cause damage.
- To prevent damage to the rear spoiler do
not lean or place anything on it.
- Only operate the rear spoiler manually when
the luggage compartment lid is close and
the rear spoiler moving parts are not
blocked. Otherwise, damage could occur.
@ Tips
Clean the rear spoiler compartment every 2 to
3 months. To function correctly, the rear
spoiler must be free of ice , snow and leaves.
Intelligent Technology
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engtne.
When a vehicle with a conventional energy sys­
tem is not driven for a long time, the vehicle bat­
tery is drained by equipment (for example, the
immobilizer). In certain circumstances , there
could may not be enough energy to start the en­
gine.
Your vehicle is equipped with an intelligent ener­
gy management system for distributing electrici­
ty. This significantly improves the starting ability
and increases the vehicle battery life.
The energy management system Is made up of
battery diagnosis, idling current management
and dynamic energy management.
Battery diagnosis
The battery diagnosis determines the vehicle bat ­
tery charge level. The sensors determine the bat­
tery voltage, the battery current, and the battery
temperature. The current charge level and the
performance of the vehicle battery are deter­
mined based on this.
Idling current management
The idling current management decreases the
energy used while parked. With the engine
switched off , it manages the energy distribution
to the different electrical components. Data from
the battery diagnosis is taken into account for
this.
Depending on the vehicle battery charge level,
electrical equipment is switched off one item af­
ter the other to prevent the vehicle battery from draining and to maintain the starting ability.
Dynamic energy management
While driving , dynamic energy management dis­
tributes the appropriate amount of energy to the
electrical equipment.
It controls the battery
charge level so that the amount of energy is not ..,_
93

Intelligent Technology
greater than the amount being generated in or­
der to maintain an optimal vehicle battery charge
level.
(D Tips
- Energy management cannot overcome the laws of physics. Note that the charge level
and length of the vehicle battery life are
limited.
- When the starting ability is jeopardized, the
(•j indicator light turns on¢ page 13.
What you should know
Maintaining the starting ability is the highest
priority.
A lot of stress is placed on the vehicle battery
when driving short distances, during city driving,
and at cold times of the year. A lot of energy is
used but little is generated. It is also critical
when the engine is not running but electrical
equipment is switched on. In this case, energy is used but none is generated .
In situations like this, energy management will
actively regulate the distribution of energy.
Long periods without use
If you do not drive your vehicle for several days or
weeks, electrical equipment is gradually 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 opening with the remote control key may not be available . These convenience functions
will be available again once you switch the igni­ tion on and start the engine.
With the engine switched off
The vehicle battery will drain if you use Infotain­ ment functions such as listening to the radio
while the engine is switched off .
If the vehicle's ability to start may be impaired by
the energy use, a message will appear in the In­
fotainment system display. The message indi­ cates that the system will switch off automatical­ly soon .
If you would like to continue using the
functions, you must start the engine.
94
With the engine running
Although e lectrical energy is generated while
driving , the vehicle battery can drain . This can
happen if little energy is generated but much is
used, and the charge level of the vehicle battery
is not optimal.
To restore the balance of energy , components
that require large amounts of energy are tempo­
rarily scaled back or switched off. Heating sys­
tems in particular 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 temporarily reduced or switched off .
These systems are available again as soon as the energy supply has been restored.
In addition, you may notice that the idle speed
has slightly increased . That is normal and no
cause for concern . By increasing the idling speed ,
the additional required energy will be generated
and the vehicle battery will be charged.
Information about data
recorded by vehicle
control modules
Your vehicle is not equipped with a crash data re­
corder . This device is installed by some vehicle
manufacturers to record data about crashes so
that it can be analyzed later. Crash data record­
ers are also called "Event Data Recorders (EDR)".
In some legal jurisdictions, it is not permitted to
access or download data recorded by pre-instal­
led crash data recorders in order to evaluate a
crash without clear consent of the vehicle owner.
Your vehicle is not equipped with a crash data re­
corder. However it does contain a variety of elec­
tronic control modules for various vehicle sys­
tems such as engine function, exhaust treatment
or airbags and safety belts.
These electronic control modules record vehicle
data during normal driving for diagnosis and re­
pair purposes. The recording capability of the
electronic control modules is limited to data only
- no sound is recorded. If the control module de­
tects a system malfunction or other change in
status, a very limited amount of data is recorded .,,.

Checking and Filling Fuel
Gasoline grade
The correct gasoline grade is stated on the inside
of the fuel filler door .
The vehicle is equipped with a catalytic converte r
and must only be d riven w it h
unleaded gasoline .
Audi recommends using TOP TIER Detergent Gas­
oline. Additiona l information on TOP TIER Deter ­
gent Gasoline can be found on the offic ial web­
site (www .topt iergas.com).
The individ ua l gasoline grades a re differentiated
by
o ctane ratings . This value is given with (R +M)/
2 equating to AKI or in RON.
The fo llow ing headings ma tch the correspon ding
sticker in the fue l filler door .
UNLEADED FUEL ONLY MIN. (R+M)/2 87
Regula r/ MIN. RON
91 Regular
Use reg ular gaso line wi th minim um 87 AK I/

If premium gasoline is not availab le, yo u can also
use reg ular gasoline 87 A KI/ 91 RO N. Howeve r
this does reduce t he engine powe r sli ght ly.
CD Note
- Fill ing the tank just one t ime with lead ed
fuel or o ther meta llic additives will cause
p erm anen t de ter io rat io n to the ca taly tic
c onve rter fu nctio n.
- W hen g asoline wi th an octane ratin g th at is

Checking and Filling
{!) Tips
The vehicle may be filled with fuel t hat has a
higher octane rating than w hat is requ ired by
the eng ine .
Blended gasoline
Use of gasoline containing alcohol or MTBE (methyl tertiary butyl ether)
You may use unleaded gasoline b lended with al­
cohol o r MTBE (commonly referre d to as oxygen­
a tes) if the blende d m ixt ure meets the fo llow ing
cr it e ria :
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
-Anti-knock index must be 87 AKI or higher.
- Blend must contain no more than
3% metha-
nol.
- Blend must contain more than
2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol )
-Ant i-kno ck ind ex mus t be 87 AKI or hig her.
- Blend must not co nta in mo re than
15% etha-
nol.
Blend of gasoline and MTBE
- Anti-knoc k index must be 87 AKI or h igher .
- Blend mus t contain no t mo re than
15% M TBE .
Seasonally adjusted gasoline
Many gasoline grades are blended to pe rform es­
pecially well for w inter or s ummer dr iving . D ur ­
i ng seasonal cha nge-ove r, we sugges t that yo u
fill up a t busy gas stat ions where the seasonal
adjus tme nt is mo re li ke ly to be m ade in time .
CD Note
- Metha nol fuels which do not meet these re ­
quireme nts may cause cor rosion and dam­

Checking and Filling
-If you a re unable to determine whether or
not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resulting from the use of fuels differ­
ent from those specified are not the respon­
sibility of Audi and are not covered under
the New Vehicle or the Emission Control
System Warranties.
- If you experience a loss of fuel economy or
driveability and performance problems due
to the use of one of these fuel blends, we
recommend that you switch to unblended
fuel.
Gasoline additives
A major concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasoline grades differ from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vital engine
parts, such as fuel injectors and intake valves. Al­
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TIER Detergent Gas­
oline. For more information on TOP TIER Deter­
gent Gasoline, please go to the official website (www .toptiergas .com).
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your en­
gine of peak performance.
(D Note
Damage or malfunction due to poor fuel qual­
ity is not covered by the Audi New Vehicle
Limited Warranty.

Refueling
' Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap .
If the power locking system should fail, you can
still open the flap manually -for detailed instruc­
tions see
~ page 234.
You can find the fuel tank capacity of your vehicle in
~ page 291.
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For more in­
formation about fuel specifications, see
~ page 231.
Your vehicle fuel tank has an on board refuelling
vapor recovery system. This feature helps to pre­
vent fuel vapors from escaping from the tank and
polluting the environment while you refuel your
vehicle . In order to fill the tank properly while
protecting the environment, please follow this
refueling procedure carefully.
.8, WARNING
Under normal operating conditions, never car­
ry additional fuel containers in your car. Gas
canisters and other containers used to trans­ port fuel can be dangerous. Such containers,
full or empty, may leak and could cause a fire
in a collision. If you must transport fuel to
use for your lawn mower, snow blower, etc .,
be very careful and always observe local and
state laws regarding the use, transportation
and storage of such fuel containers. Make cer­
tain the container meets industry standards
(ANSI/ASTM F852 -86).
CI) Note
Never drive your vehicle until the fuel tank is
completely empty. The irregular supply of
fuel can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.

Fueling procedure
Fig. 174 Right rear side of the vehicle: opening the fue l
filler door
Fig . 175 Engaged fue l pump nozz le
The fuel filler door is unlocked or locked by the
central locking system .
.. Press on the fuel filler door to open
-arrow- ~
fig. 174. Your vehicle comes with a
new tank system without a cap.
.. Insert the fuel pump nozzle all the way into the
tank filler neck¢
fig. 175. Make sure it is cor ­
rectly locked in place.
• Begin fueling. Once the pump no zzle switches
off, the fuel tank is "full" . Do not fill the tank
more . Otherwise the expansion space in the
tank will be filled .
.. Pull the pump nozz le out of the tank filler neck
five seconds after it has switched off, so that
the rest of the fuel can flow out of the pump
nozzle into the filler neck.
.. Close fue l filler door until it latches.
The correct f uel type for your vehicle can be
found on a label located on the inside of the fuel
filler door. For additional information on fuel,
see ¢
page 231.
The fuel tank capacity of your vehicle is listed in
the
Technical Data section Q page 291 .
Checking and Filling
A WARNING
-Fuel ignites easily and can cause serious burns
and other injuries.
- Do not smoke or have an open flame in the
area when fueling your vehicle or filling a
fuel container because this increases the
risk of an explosion .
- Follow legal requirements when using, stor­
ing and transporting fuel containers .
- For safety reasons, we recommend not car­
rying fuel containers . The container could be
damaged in an accident and leak fuel.
- If you must transport fuel in a fuel contain­
er, note the following:
- Never fill the fuel container with fuel
while it is in or on the vehicle. Static elec­
tricity is discharged when filling which can
cause the fuel vapors to ignite and in ­
creases the risk of an exp losion . Always
place the container on the ground when
fill ing it.
- The fuel pump nozzle must be inserted as
far as poss ible into the filler opening on
the fuel container .
-If the fuel container is made of metal, the
fuel nozzle must always be in contact with
the container when filling it with fuel. This
prevents static electricity from discharg­
ing .
- Never spill fuel in the vehicle or the lug­
gage compartment. Evaporated fuel is
ex­
plosive and increases the risk of serious in­
jury or death.
(D Note
-Remove spilled fuel from vehicle pa int im­
mediately, because it can damage paint.
- Never drive until the fuel tank is completely
empty . The irregular supply of fue l that re­
sults from that can cause engine misfires.
Uncombusted fuel will enter the exhaust
system and increase the risk of damage to
the catalytic converter.
@) For the sake of the environment
Do not overfill the fuel tank, otherwise fuel
can leak out when the veh icle is warming up.

Check ing and F illing
Using the proper engine oil is impo rtant for the
functionality and service life of the engine. Your engine was facto ry-filled with a h igh-quality oi l
which can usually be used throughout the entire
year.
@) Note
Your Limited New Vehicle War ranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's
Manual and Warran ty
& Maintenance booklet.
- Use only a high quality eng ine oil t hat ex-
p ressly complies with the Audi oil qua lity
standard specified for your vehicle's engine .
Using a ny o ther oil can cause serious engine
d am age.
- D o not mix any lubricants o r other addit ives

Engine oil consumption
T he engine in your vehicle depends on an ade­
quate amoun t of oil to lubricate and cool all of
i ts moving par ts.
In order to p rovide effective lubr ication and cool­
ing of internal engine components, all interna l
combustion engines consume a cer tain amount
of oil. Oi l co nsumption varies from engine to en ­
g ine and may change significant ly over the life of
the eng ine . Typically, eng ines with a specified
238
b reak -in period (see q page 57) cons ume more
oi l during the break-in period than they consume
after o il consumption has stab ilized.
U nder normal cond itions, the ra te of oil con ­
s u mption depends on the q ua lity and viscos ity o f
the oil , the RPM (revo lutions per minute) at
which the engine is operated, the amb ient tem­
