Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers fo r the express purpose of capturing
data for retrieval after an accident or crash
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, eng ine function, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during normal vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited pe riod of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only
be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of vehicle control. It works
only when the engine is running. ESC detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering assistance to help hold the
vehicle on the driver's intended course. The in­
dicator light
G) in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
physics. It wi ll not always be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of
dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it wou ld on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered.
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations as at lower
speeds.
Always adjust your speed and driving style to
road , traffic §&and weather conditions. ESC
cannot override the vehicle's physical limits,
increase the available traction, or keep a vehi­
cle on the road if road departure is a result of
driver inattention . Instead, ESC improves the
poss ibility of keeping the vehicle under con­
t rol and on the road dur ing extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle go ing in the intended di­
rection . If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC includes and/or works togethe r with the
anti- lock brake system (ABS), brake assist sys-
tem and anti-slip regu lation (ASR). ESC is .,..

Battery diagnosi s
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 battery.
Idling current management
I dling current management reduces energy
consumption while the vehicle is standing.
With the ignition switched off, it controls the
energy supply to the various electrical compo­
nents. Data from battery diagnosis is consid­
ered.
Depending on the battery's state of charge,
individual consumers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability.
Dynamic energy management
While the vehicle is being driven, dynamic en ­
ergy management distributes the energy gen­
erated according to the needs of the individu­
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 starting ability is threatened, you are informed by a warning
~page 149,
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 cold time
of year. Abundant electrical energy is re­
quired, but only a little is generated.
It is also
critical if the engine is not running and electri- cal components are turned on.
In this in­
stance energy is being consumed but none is
being generated.
It is in precisely these situations that you will
notice energy management actively regulat­
ing 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 starting capability over a longer period.
Take into consideration that when you unlock
your vehicle, some convenience functions ,
such as the remote key or power seat adjust ­
ment, may not be available. The convenience
functions will be available again when you
turn on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for example, with
the engine turned off, the battery is being dis­
charged.
If starting capability is jeopardized due to en­
ergy consumption, a message appears in the
driver information display.
You have to start the engine to charge the
battery.
With the engine running
Although electrical energy is generated when
the vehicle is being driven, the battery can be­
come discharged. This happens mostly when
little energy is being generated and a great
deal consumed and the battery's state of
charge is not optimal.
To bring the energy balance back into equili­
brium, consumers which require especially
large amounts of energy are temporarily cut
back or switched off . Heating systems in par­
ticular 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 will be avai lable again as
soon as the energy ba lance has bee n restored.
You will also notice that engine idle speed has
been increased s lightly. This is normal and not
a cause for concern. By increasing engine idle
speed the additiona l energy required is gener­
ated and the battery is charged .
Driver notification in the instrument
cluster display
If battery power drops into the range where it
can lim it the ab ility of the engine to start, th is
i s shown in the inst rument cluster display
with the following driver message:
(•) Low battery charge : battery will be
charged while driving
This notification reminds you that the starting
capability of the engine may be l imited. As
soon as you start driving aga in, the battery
w ill be recharged and the notification will go
out.
Driver notification appears and goes out
again
If th is driver notification appears after the ig­
nition is turned on or while driving and it goes
out again after a wh ile, the battery has been
adequately recharged.
Driver notification appears and does not
go out again
If this driver notification appears after the ig­
n ition is turned on or while driving and does
not go out again, the battery's state of charge
is not in the optimal range. Starting ability is
restr icted. Have the battery checked as soon
as possible by an author ized Audi dealer or
qualified workshop.

Detergent additives in the oil will make fresh
oil look dark after the engine has been run­
n ing for a short time . This is norma l and is not
a reason to change the o il more often than
recommended.
D amage o r m alfu nctions due to lac k of
m ainten ance
It is essen tial that yo u change your oil at the
recommended inte rva ls using only engine oil
that complies with A udi oil standard
VW 502 00 . Your Lim ited New Vehicle War­
ranty does not cover damage or malfunctions
due to failure to follow recommended mainte­ nance and use requ ireme nts as set forth in
the Audi Owner 's Manual and Warranty
&
Maintenance book let . Your dea ler will have to
deny warranty coverage u nless you p resent to
the dea ler proof in the form of Serv ice or Re­
pa ir Orde rs that all scheduled maintenance
was performed in a timely manner.
Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all
of its moving ports.
I n o rder to prov ide effective l ubr ication and
cooling of internal engine components, a ll in­
ternal comb ustion engines consume a certain
amo unt of oi l. Oi l cons umption varies from
engine to engine and may change significantly
over the life of the eng ine . Typ ically, eng ines
with a specified break-in per iod (see
¢ page 150) consume more o il during the
break-in per iod than they consume after oil
consumption has stab ilized .
Under normal conditions, the rate of oil con­
sumpt io n depends on the quality and viscosity
of the oil, the RPM (revolutions per m inute) at
which the engine is ope rated, the ambient
temperature and road condi tions. Furt her fac­
tors are the amo unt of oil d ilution from wate r
condensation or fuel residue and the oxida­
tion level of the oi l. As any engine is subject to
wear as mileage bui lds up, the oil consump ­
tion may increase over time until rep lacement
of worn components may become necessary.
Checkin g and fillin g 169
With a ll these variab les coming into p lay, no
standard rate of oil consumption can be es ­
tab lished or spec ified . There is no alte rnative
to regular and frequent check ing of the o il lev­
el, see
Note .
If the yellow engine oil leve l warning symbo l
in the instrument cluster
Ill li ghts up, you
sho uld check the oil leve l as soon as possib le
with the oil dipstick¢ page 170. Top off the
o il at your earliest convenience ¢
page 170 .
A WARNING
Before you check anything i n the engine
compartment, always read and heed a ll
WAR NINGS ¢
& in Working in the engine
compor tment on page 165.
(D Note
D riving w it h an insufficient o il level is like­
l y to cause severe damage to the engine.
© Tips
- The oil pr essur e warn ing display. is
not an indicator of th e oil level. Do not
rely on it . Instead, che ck the oil level in
your engine at regu lar int ervals, pr ef­
erably e ach time you r efuel, and always
before going on a long trip .
-If you have the impression yo ur engi ne
cons umes excess ive amoun ts of oil, we
recommend that you consu lt your Aud i
dea ler to have the cause of your concern
properly d iagnosed. Keep in mind that
the accurate meas urement of o il con­
sumption requires great care and may
take some t ime . Your Audi dea ler has in­
st ruct ions about how to measure oil con­
sumption acc urately.

188 Tire s and wheel s
forget the spare tire. If the pressure in any tire
is too high when the tire is "cold," let air out
of the tire slowly with the edge of the tire
ga uge and keep checking the pressure until
you reach the pressure that is correct for the
load (passengers and luggage) and kind of
driving you plan to do.
If the pressure in any tire is too low, note the
d ifference between the pressure in the cold
tire and the pressure you need and add the air
that you need to reach the correct pressure for
the vehicle load (passengers and luggage) for
the tires on your veh icle as listed on the on
your ve hicle and in this manua l and the kind
of dr iving you p lan to do .
Never exc eed th e maximum inflati on pres­
sure listed on th e tir e s idewall for any rea ­
s on.
Remembe r that the vehicle manufacturer, not
the t ire manufactu rer, determ ines the correct
tire pressure for the t ires on your vehicle.
It is important to check the tire pressure when
the t ires a re cold .
- Read the requ ired tire press ure from the tire
pressure label located on driver's side B-pil­
lar .
- Turn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressure gauge on the valve.
- The tire pressures sho uld only be checked
and adjusted when the tires are cold. The
slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Re insta ll the valve stem cap on the valve.
Wh en should I check the tir e pr essure?
The correct tire pressure is espe cially impor ­
tant at high speeds . The pressure should
therefore be checked at least once a month
and a lways before starting a journey.
When should I ad ju st the tire pressures?
Adj ust the t ire p ressu re to the load yo u are
carry ing . After changing a wheel
or replacing whee
ls you have to adjust the tire p ressures
o n all whee ls. In addition, yo u m ust then initi­
alize the new tire press ures in the t ire pres­
s u re monitoring system¢
page 199.
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire fa ilure, loss of
control, collision, serious pe rsonal injury
or even death.
- When the warn ing symbol
RI] appears in
the instrument cluster, stop and inspect
the t ires.
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wea r and
can affect the handling of the vehicle and
s topping ability.
- I nco rrect tire pressures and/or underin­
f lation can a lso lead to s udden t ire fail­
ure, including a blowout and su dden de­
flation, ca using loss of veh icle cont ro l.
- The drive r is responsible for the co rrec t
tire pressures for all tires on the veh icle .
The applicable pressure values are loca t­
ed on a sticker on the driver's side B -pil­
lar.
- On ly when all tires on the vehicle are fil­
led to the correct pressu re, the tire pres­
sure mon itor ing system can work cor­
rectly.
- The use of incorrect tire pressu re va lues
can lead to acc idents or other damage.
Therefore it is essential that the driver
observe the spec ified t ire pressure values
for the tires and the correct pressures for
the function of the t i re p ress ure monito r­
ing system.
- Always inf late tires to the recommended
and correct t ire pressure before dr iv ing
off.
- Driving with unde rinf lated tires bend
mo re, letting them get too hot resulting
in tre ad separation, sudden tire failure
and loss of cont ro l.
- Excessive speed and/overloading can
cause heat b uild- up, sudden tire failure
and loss of cont ro l.

remain continuo usly illuminated . This se­
quence will continue upon subsequent vehicle
start-ups as long as the ma lfunction ex ists.
When the malfunction indicator is illuminat­
ed, the system may not be able to detect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea­
sons, including the installation of replace­ ment or alternate tires or wheels on the vehi­
cle that prevent the TPMS from functioning properly . Always check the TPMS malfunction
tellta le after replacing one or more t ires or
wheels on your veh icle to ensure that the re­
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
Applies to vehicles: with tire pressure monitoring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
F ig. 143 Display : underi nflat io n warn ing
Using the ABS sensors, the tire pressure moni­
toring sys tem compares the t ire tread circum­
ference and vibration characteristics of the in­
d iv idual tires . If the pressure decreases in one
or more tires, th is is indicated in the instru­
ment clus ter with a warning symbo l
ail and a
message<>
fig. 143. The dr iver message in the
display goes out after 5 seconds . The driver
message can be displayed again by pressing
the
! CHECK I button @¢ page 10, fig . 3 . If on ­
l y one tire is affected, the display will indicate
its pos ition.
The tire press ure monitoring m ust be reset in
the menu display each time the pressures are
ad justed (e.g. when switching between parti- al and fu
ll load pressure) or after changing or
replacing a tire on your vehicle<>
page 201.
The TPMS indicator only mon itors the t ire
pressure that you have previously stored . You
can find the recommended tire pressures for
your vehicle on the label on the driver's door
pillar
¢ page 185.
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the t ire pressure in one or more tires is too
low,
- the tire has structural damage,
- the tire pressure was changed, wheels rotat -
ed or replaced but the TPMS was not reset

fuses in your vehicle. Fuses with the proper
ampere ratings are available at your author ­
ized Audi dealer.
A WARNING
-
Do not repair fuses and never replace a
b lown fuse with one that has a higher amp
rating. This can cause damage to the elec­
trica l system and a fire.
