The engine drives the generator, wh ich generates
electricity; the fue l consumption also increases
with the demand for electricity. Therefore, switch
e lectrical equipment off when you no longer
need it. Examples of equipment that use a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating*.
CD Note
Do not leave engine idling unattended after
starting. If warning lights should come on to
ind icate improper operation, they would go
unheeded. Extended idling also produces
heat, wh ich could result in overheat ing or
other damage to the vehicle or other p roper-
ty.
CD Note
-Have your vehicle maintained properly and
i n accordance with the service recommenda­
tions in your Warranty
& Ma intenance book­
l et. Lack of proper maintenance as well as
i mproper use of the vehicle will impair the
function of the emission control system and
could lead to damage.
-Do not alter or remove any component of
the Emission Control System unless ap­ proved by the manufacturer.
-Do not alter or remove any device, such as
heat shie lds, switches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other
important vehicle components .

Assistance systems
-Please note that unconsciously "resting"
your foot on the accelerator pedal prevents
the cruise control from braking. This is be­
cause pressing the accelerator pedal over­
rides the cruise control system.
- If a brake system malfunction such as over­
heating occurs when the cruise control sys­
tem is switched on, the braking function in
the system may be switched off. The rest of
the cruise control system funct ions remain
active as long as the
@;\IM~ (USA models) /
l'I (Canada models) indicator light is on.
(D Tips
The brake lights turn on when the brakes are
applied automatically.
Changing the speed
.,. To incr ease or decrease the speed in incre­
ments, tap the lever toward
010 ¢ page 93,
fig . 102.
.. To increase or decrease the speed quickly, hold
the lever in the
0 10 direction until the de­
s ir ed speed is displayed.
You can a lso press the accelerator pedal down to
increase your speed, for example if you want to
pass someone. The speed you set earlier w ill re­
sume as soo n as you release the accelerator ped­
al.
However, if you exceed your saved speed by 5
mph (10 km/h) for longer than 6 minutes, the
cru ise control system turns off temporarily.
The
green@;\1)~1~ (USA mode ls) !l'I (Canada mod ­
els) indicator light in the speedometer turns off
and the stored speed is maintained.
Preselecting a speed
You can pre-select your desired speed when the
vehicle is stationary.
.. Switch the ignition on .
.. Pull the lever into position (D i::> page 93,
fig. 102 .
.. To increase or decrease the speed, push the lev­
er toward
0 10 .

Switching off
Deactivating temporarily
.. Press the brake pedal, or
.. Press the lever into position @(not clicked into
place)
¢ page 93, fig. 102, or
.. Dr ive for longer than 5 minutes faster than 5
mph (10 km/h) above the stored speed.
Switching off completely
.. Press the lever into position@(clicked into
place), or
.. Switch the ignition off .
The speed you stored will be maintained if the
cruise contro l has been switched off temporarily .
T o resume the stored speed, release the brake
pedal and pull the lever into position

" N .... 0 0 :c ' Intelligent Technology Electronic Stabilization
Control (ESC)
Description
The ESC increases driving safety. It reduces the
risk of slipping and improves driving stability.
ESC detects critical situations such as when the
vehicle is oversteering and understeering or the
wheels are spinning. The vehicle is stabilized by
applying the brakes or reducing engine torque .
When the ESC engages,
the G1 indicator light
b links in the instrument cluster.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the whee ls from locking when brak­
ing. The vehicle can still be steered even during
hard braking. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake pedal indicates that the system is acting to
stabilize the vehicle .
Brake assist system
The brake assist system can decrease braking dis­
tance. It increases braking power when the driver
presses the brake pedal quickly in emergency sit­
uations . You must press and hold the brake pedal
until the dangerous situat ion is over . In veh icles
w ith adaptive cruise contro l*, the brake assist
system is more sensitive if the distance detected
to the vehicle dr iv in g ahead is too small. On
ve hicl es w ith activated and functioning night vi­
sion assist*, the brake assist system can respond
more sensitively if there is a warning .
Anti-Slip Regulation (ASR)
ASR reduces engine power when the drive wheels
begin spinning and adapts the force to the road
conditions. This makes it easier to start, acceler­
ate and drive up hills.
Electronic differential lock (EDL)
EDL applies the brakes to a wheel that starts
sp inn ing and transfers the drive power to the
other driving wheels. This functio n is not availa­
ble at higher speeds.
Intelligent Technology
In extreme cases, EDL automatica lly switches off
to keep the brake on the braked whee l from over ­
heating. The vehicle is still working correct ly. ED L
will switch on again automatically when condi­
tions have returned to normal.
Steering recommendation
T he ESC he lp s to stabilize the vehicle by changing
the steering torque .
In veh icles with dynamic steer ing*, ESC also
helps to stab ilize the steer ing in crit ica l situa­
tions.
Selective wheel torque control
Selective wheel torque control is used when driv­
in g on curves.
The front wheel on the inside of the curve or both
wheels on the inside of the curve are braked se­
lectively as needed. This allows more precise driv­
in g in curves . The applicable system may not acti­
vate when dr iv in g in wet or snowy conditions .
Automatic post -collision braking system
Th e "automat ic post-collis ion braking system"
can help to reduce the risk of sliding and of addi­
t iona l co llisions after an acc ident. If the airbag
control module detects a co llision above a certa in
vehicle speed, the veh icle is braked by the ESC.
The vehicle does not brake automatically if :
- the dr iver presses the acce lerator pedal, or
- the braking force generated by the pressed
brake pedal is greater than the braking force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electri ­
cal system are not functioning.
A WARNING
,--
- The ESC and its integrated systems cannot
overcome the lim its imposed by natural
p hys ical laws. This is especially important
on slippery or wet roads. If the systems be­
g in acting to stabilize your vehicle, you
should immediately alter your speed to
match the road and traffic conditions. Do
not let the increased safety provided tempt

u. co .... N
" N .... 0 0 :c ' To restore the balance of energy, components
that require large amounts of energy are tempo­
rari ly 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 defogger is not working, then it
has been temporar ily reduced or switched
off .
These systems are available again as soon as the
e n ergy supp ly 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 add itiona l required e ne rgy w ill be generated
and the vehicle battery w ill be charged.
Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
Event Data Recorder
This vehicle is equipped with an Event Data Re­
corde r (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like situa ­
tions, such as an airbag deployment or hitting a
road obstacle, data that will assist in understand ­
ing how a vehicle 's systems performed. The EDR
is designed to record data re lated to vehicle dy ­
namics and safety systems for a short period of
time, typically 30 seconds or less. The EDR in this
vehicle is designed to record such data as :
- How various systems in your vehicle were oper­
ating;
- Whether or not the driver and passenger safety
belts were buckled/fastened;
- How far (if at all) the driver was depressing the
acce lerator and/or brake pedal; and,
- How fast the vehicle was traveling.
These data can he lp prov ide a better understand­
ing of the circumstances in which crashes and in­
ju ries occur. NOTE: EDR data are recorded by your
vehicle only if a non-trivia l crash situation occurs;
no data are recorded by the EDR under normal
driving conditions and no personal data (e.g.,
name, gender, age, and crash location) are re­
corded. However, other parties, such as law en-
Intelligent Technology
forcement, could combine the EDR data with the
type of personally identifying data routinely ac­
quired during a crash investigation.
T o read data recorded by an EDR, special equip­
ment is required, and access to the vehicle or the
EDR is needed. In addition to the vehicle manu­
facturer, other parties, such as law enforcement,
that have the special equipment, can read the in ­
formation if they have access to the vehicle or the
EDR .
Some state laws restrict the retrieval or down­
loading of data stored by ED Rs installed in a vehi­
cle for the express purpose of retrieving data af­
ter an accident or crash event without the own ­
er's consent .
Audi will not access the EDR and/or simi lar data
or give it to others -
- un less the vehicle owner (or lessee if the vehi ­
cle has been leased) agrees; or
- upon the official request by the police; or
- upon the order of a court of law o r a govern-
ment agency; or
- for the defense of a lawsuit through the judicial
discovery process.
- Aud i may also use the data for resea rch about
veh icle operation and safety performance or
provide the data to a third party for research
purposes without identifying the specific vehi­
cle or information about the identity of its own­
er or lessee and only after the recorded vehicle
data has been accessed.
Vehicle control modules
Your vehicle is also equipped with a number of
electronic control modules for various vehicle
systems, such as engine management, emission
control, airbags, and safety belts .
These electronic control modu les record data
during normal vehicle operation that may be
needed by trained technicians for diagnostic and
repair purposes. The recording capability of these
modules is limited to data (no sound is record­
ed) . Only a small amount of data is actually re­
corded over a very lim ited period of time, or stor­
ed when a system fault is detected by a control
module . Some of the data stored may relate to
