Intelligent technology 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 for the express purpose of capturing
data for retrieval after an accident or crash
event. EDR's are sometimes called "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.
Although 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, engine function, emis
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l 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 period 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
skidding and loss of veh icle control. It works
only when the engine is running. ESC detects
Intelligent technology 189
certain difficult driving situations, 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 ass istance to help hold the
vehicle on the driver's intended course. The in
dicator light
JjJ 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 will 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 would 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 than at lower
speeds.
Always adjust your speed and driving style to
road, traffic and weather conditions. ESC can
not override the vehicle's physical limits, in
crease the available traction, or keep a vehicle
on the road if road departure is a result of
driver inattention. Instead, ESC improves the
poss ibility of keeping the vehicle under con
trol and on the road dur ing extreme maneu
vers by usin g the driver 's steering inputs to
help keep the vehicle going 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 together with the
anti- lock brake system (ABS), brake assist sys -
tem, anti-slip regu lation (ASR), electronic

Indicator lights
I§!/. Rear spoiler: system malfunction!
The rear spoiler may not have extended due to
a malfunction. This could change the vehicle's
driving characteristics at high speeds. Do not
exceed 85 mph (140 km/h). Drive to your au
thorized Audi dealer immed iately to have the
malfunction corrected . The co lor of the indica
tor light depends on the veh icle speed.
A WARNING
-Driving at higher speeds without the rear
spoiler deployed can impair handling char
acteristics, making the vehicle harder to
control.
-Always make sure that the spo iler is de
p loyed when driving at speeds over
85 mph (140 km/h) . If the rear spoiler
warn ing/ indicator light in the instru
ment 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 possible by an authorized Audi
dealer or qualified workshop.
- Always obey speed limits and other traf
fic laws.
A WARNING
Improper operation of the rear spoi ler 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 the vehicle or apply force to
the rear spoiler -it could be damaged.
- Only operate the rear spoiler manua lly
when the rear lid is closed . Otherwise,
damage could occur.

196 Intelligent technology
Basically, energy management consists o f
battery diagnosis, idling current manage
ment
and dynamic energy man agement.
Battery diagnosis
Battery diagnosis continuously dete rm ines
the state of the battery. Sensors determine
battery vo ltage, 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 contro ls the
energy s upply to the various e lectrica l compo
nents . Data from battery diagnosis is consid
ered.
D epending on the battery's state of charge,
individual consumers are gradually turned off
to prevent excess ive discharge of the battery
and thus mainta in start ing capability.
Dynamic energy management
While the vehicle is being dr iven, dynamic en
ergy management distributes the energy gen
erated according to the needs of the individu
a l components. It regu lates 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 ab ility is threatened, the indi
cator light (•) appears ¢
page 16.
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. Abu ndant electrical energy is re- quired, but on
ly a little is generated . It is also
critical if the engine is not running and electri
ca l components are turned on. In this in
stance energy is be ing consumed but none is
being generated .
It is in precise ly these situations that you will
notice energy management active ly regu lat
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, e lectrica l compo
nents are gradually cut back or switched off .
This reduces energy consumption and main
ta ins start ing capability over a longer period .
Some of the convenience functions may not
operate, such as the interior l ights or the
power seat adjustme nt. The convenience
funct ions will be available again when you
switch on the ignition and start the eng ine.
With the engine turned off
If you listen to the radio, for examp le, w ith
the engine turned off or use other MMI func
tions, the battery is be ing discharged .
If starting capability is jeopardized due to en
ergy consumption, the following warning ap
pears in the MMI display:
Please start the engine soon or the system
will be turned off.
The warning indicates that the system will be
turned off automatically after 3 minutes . If
you w ish to continue using the functions, you
have to start the eng ine.
With the engine running
Although e lectrical 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 opt imal.
To bring the energy ba lance back into equili
brium, consumers which requ ire espec ially
large amounts of energy are temporar ily cut
back or sw itched off. Heating systems in .,.
particular 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 availa ble again as soon as the energy balance has
been restored.
You will also notice that engine idle speed has been increased slightly. This is normal and not
a cause for concern . By increasing engine idle
speed the additional energy required is gener
ated and the battery is charged.

Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam
aged.
T his is especially true for vehicles with low
slung chassis (sports chassis) * and fully load
ed veh icles .
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- T he water must not be any h igher than the
bottom of the veh icle body.
- Do not d rive faster than wa lking speed.
..&, WARNING
After driving through wate r, m ud, slush,
etc., the brakes may be slow to take effect
because o f wet brake rotors and pads . Dry
the brakes first by braking carefully to re
store the full braking effect.
(D Note
- Vehicle components such as the eng ine,
transmission, suspension or e lectrical
system can be severely damaged by driv ing through water.
- Check the depth o f the water before driv
ing through it.
- Do not s top the veh icle, drive in reverse
or switc h the engine off when driving
through water.
- Keep in mind that oncoming vehicles may create waves that raise the water
level and make it too deep for your vehi
cle to drive through safely.
- Avoid driving thro ugh sa lt water because
it can ca use corrosion.

Warming up and
cooling down
By carefully warming up and cooling down
your vehicle, you can help ensure that it is not
overstressed unnecessar ily during sporty dr iv
ing.
When warming up, the vehicle is dr iven at a
maximum engine speed of 6000 RPM in order
to raise the engine o il temperature to a mini
mum of 140
°F (60 °() . The t ires a lso on ly
reach the ir full road holdi ng capabi lity once
they have warmed up.
The cooli ng fan can cont inue to run in your ve
hicle after the engine is switched off . Howev
er, driving the veh icle to coo l it down is pa rti c
ul arly important. Dur ing spo rty driving , the
engine and b rakes, the exhaust system, and
the transmission a ll become extremely hot.
Before you park the vehicle, you should drive
it for a few miles/kilometers at light load in
the low rpm range to allow it to cool down .
Catalytic converter
App lies to vehicles: wi th gaso line e ngi ne
It is very important that your emission con
trol system (catalytic converter) is function
ing properly to ensure that your vehicle is run
ning in an environmentally sound manner.
"' Always use lead-free gasoline c:> page 208,

@ Tips
The consumption estimates as published by ENVIRONMENTAL PROTECTION AGENCY (EPA) and Transport Canada may not corre
spond to your actual consumption on the
road, wh ich will vary depend ing upon vehi
cle load and speed, road and weather con
ditions, tr ip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac
celerating.
~ Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are ac
celerating . If you anticipate what is go ing to
h appen next, you will need to b rake less and,
thus, accelerate less. Let the vehicle coast
wheneve r poss ible -fo r example when you see
that the nex t tr affic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
~ T ry and keep well below your car's max imum
speed.
Accelerating gent ly reduces fuel consump
tion, engine wear, and does not disturb the
environment.
Fuel consumption, exhaust emissions and en
g ine no ise increase d ispropo rtionately at high
speeds. If you dr ive at approxima tely three
q uarters of top speed, fue l consumption will
be red uced by one ha lf. Never dr ive faste r
than the posted speed limit and wea ther con
d itions permit.
Reducing unnecessary idling
E ven when your car is just idling it burns up
fuel.
~ S hu t the engine off when you a re not dr iv ing
t h e vehi cle.
Dri vin g and en vironm ent 201
~ Do not warm up the vehicle by lett ing the
engine run at id le .
It makes sense to shut off the engine in traffi c
jams, when wa it ing fo r tra ins to pass at rail
road crossings, or at traffic lig hts that have
long waits on red. T urning the engine off for
just 30-40 seconds saves more fuel than is burned start ing the e ngine again.
It takes a long time for the engine to warm up
fully when it is runn ing at id le. However, wear
and noxious emissions are especia lly high
when the engine is warm ing up. So you should
drive away as soon as you start the engine and
avo id running at high rpms while the engine is
still warming up .
(D Note
Do not leave engi ne idling unattended a f
ter start ing . If warning lights sho uld come
on to i ndicate improper operat ion, they
would go unheeded. Extended idling a lso
p rodu ces hea t, w hich could re sul t in ove r
hea ting or othe r dam age to the veh icle or
other p roperty .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
~ Have your ve hicle serviced at reg ula r i nter-
vals.
By having your veh icle regula rly serviced by an
Audi deal er he lps to ensure that it runs prop
erly and economically. The condition of your
vehicle not only affec ts its sa fe ty and ability to
hold its value, it also affects
fuel con sump
tion .
Check your oil each time you fill your tank.
The amou nt of oi l used is re lated to eng ine
load and speed.
It is normal fo r th e oil consumption of a new
engine to reac h its lowest value after a certa in
mileage has bee n driven .
