A WARNING
Following ot her vehicles too closely in­
creases the risk of a crash and serious per­
sonal injury .
- Following other vehicles too closely, par­
t icularly at higher speeds increases the
risk of collis ions and serious pe rsonal in­
Jury.
- Setting short distances to the traffic
ahead reduces the time and distance
available to br ing you r vehicle to a safe
stop and makes i t even mo re ne cessary
to pay close attention to traffic.
- Always select a speed and distance to
traffic ahead that is safe and appropr iate
under the prevailing traff ic, road, weath ­
er and Lighting conditions .
- Never re ly on the dis tance control fea­
ture of ACC a lone to p reven t rear -end col­
lisions. Always be prepared to brake and
take evasive act ion to avoid co llisions
and other acc ident situations.
- Never allow the closing speed between
you and other vehicles to be so h igh that
the adaptive cruise control may not be
able to slow your vehicle safe ly. If clos­
ing speed is too high, you must apply the
brakes yourself to reduce the risk of a
rear-end c rash.
- Always select a g reater following dis­
tance to the veh icle ahead on wet roads
than o n dry roads.
- Always read and heed the information

System limitations
General information
Applies to vehicles: with adaptive cruise co ntrol
The radar sensor has limits that the driver
must know to be able to use ACC properly .
The adaptive cruise control works within lim­ its that are also related to radar sensor range
and sight distance . In some situations ACC
may react unusually or late from the driver's
point of v iew. Therefore, always be attent ive
to what is happening around you and always
be ready to intervene, if necessary:
-when driving around curves ¢page 127
- when vehicles up front are not in line with
your vehicle ¢ page 128
- when other veh icles are changing lanes
i=> page 128
- when other vehicles are difficult to detect
i=> page 128
- when vehicles up ahead are not moving or obstacles are in your travel lane i=>page 128
A WARNING
The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Moving veh icles up ahead may not be
prompt ly detec ted or may not be detected
a t all.
- Always pay careful att ention to the traf­
fic s ituation and be ready to intervene
and be re ady to take comp lete cont rol
whenever necessary.

Audi braking guard
Description
Applies to vehicles: with a daptive cruise co ntrol
Audi braking guard warns you of a possible
collision with a moving vehicle up ahead .
Fig. 149 Display in the instrument cluster
The Audi braking guard is act ive from a speed
of app rox. 20 mph (30 km/h) and wor ks w ith­
in the system limits¢
page 127 even when
the adaptive cruise contro l is deactivated .
A radar sensor is bu ilt into the front of the ve ­
h icle
¢page 116, fig. 130. The system is in ­
tended to measure the distance to reflect ive
surfaces .
If a measurement is not possible,
the system does not respond.
When the meas urement has been taken, the
system can recognize a possibly hazardous sit ­
uation, for example, whe n a vehicle up ahead
in your lane of trave l sudden ly brakes or when
your own vehicle is moving at high speed to­ wards a much slower vehicle up ahead . As
soon as the system senses that a possible col­
lision with the vehicle up ahead can only be
avoided by immed iate full brake app lication or
by an avoidance maneuver, a warning appea rs.
The system has a defau lt response time to be
able to signal before a collision occurs. This
system response time is automat ica lly re­
duced if you acce lerate actively, fo r example
to join a highway . B rak ing, tra nsverse acceler­
ation and the steering ang le can lead to a re­
duced system response time. The warning is
deactivated if you begin to overtake with full
acceleration .
Adapti ve crui se control 129
The system can make you aware o f two diffe r­
ent hazardous situations:
Distance
T he distance warning is given if the system
ca lculates that there is not enough distance
to the vehicle up ahead a pe riod of more than
S seconds . If the distance is less than 30 feet
(9 meters) at SO mph (80 km/h), for examp le,
an optical display comes on in the instrument
cluster¢
fig. 149.
If the vehicle ahead brakes sharp ly, Audi brak ­
ing guard cannot help you to avoid a collision,
even in the case of an immediate response.
Take immed iate action to avoid the co llision
and increase the distance to the vehicle up
ahead.
Speed
If there is a much slower vehicle moving up
ahead in your lane, or if the vehicle ahead
brakes sharply, the Aud i brak ing guard calcu­
lates the po int from which a collision can only
be avoided by full braking or by an avoidance
maneuve r. If a warning does sou nd, a poss ible
collision with the ve hicle in front can on ly be
avo ided th rough an evas ive maneuve r or by
braking.
T he warning is given in two stages :
-Pre -warning: A visual display appears in the
instrument cluster and a warning tone
sounds.
- Acute warning : If you do not respond to the
pre-warn ing, the second stage warning is
given. A quick brake application helps to di­
rect your attention to the road and traffic
situat ion.
Under heavy braking, the brake ass istant
¢
page 116 also helps you benef it from maxi­
mum brak ing eff ic iency.
A WARNING
I nattention can cause collisions, other ac­
cidents and ser ious perso nal i nju ries.

130 Adapti ve crui se co ntrol
- Always pay close attention to the traffic,
even when the Audi brak ing guard is
switched on. The Aud i brak ing guard pro­
vides a warning but does not brake the
car for you . You must apply the brakes
yourself!
- Always keep the safe and legal distance
between your vehicle and veh icles up
ahead.
-Audi braking guard works within limits and w ill not respond outs ide the system
limits, for example when approaching a
stopped vehicle or stationary obstacle
(end of a traff ic jam or veh icle that has
broken down in traffic).
- Always remember that the radar sensor
for the A udi braking guard works within
defined detection and range limits that
may prevent the proper detection of oth­
er vehicles.
- The radar sensor's function and range
can be reduced by rain, snow and heavy
spray. Moving vehicles up ahead may not
be promptly detected or may not be de­
tected at all.
- Always pay careful attention to the traf­
fic s ituation and be ready to intervene
and be ready to take complete control
whenever necessary.
- Reflective surfaces includ ing crash barri­
ers or tunnel entrances may impair the
function of the radar sensor .

Automatic
transmission
tiptronic
Introduction
The automatic transmission is controlled elec­
tronically. The transmission upshifts or down­
shifts automatically depending on which drive
program is selected. The power is transferred
by a torque converter .
When a
mode rate d riv in g s ty le is used, the
transmission selects the most econom ica l
driving mode. It w ill then change up early and
delay the downshifts to g ive better fuel econ­
omy.
T he transmission switches to a sporty mode
after a k ick-down or when the driver uses a
spo rty driving sty le characterized by quick ac­
celerator pedal movements, heavy accelera­
tion, frequent changes in speed and traveling
at the maximum speed.
If desired, the driver can a lso select the gears
manually ( tiptronic mode ) ¢ page 142.

tions by hand
c::> page 142 .
On slopes, activate the parking brake first and
then move the selector lever to the P position.
This prevents too much stress from being
placed on the locking mechanism.
A WARNING
- Unintended vehicle movement can cause
serious injury.
- Never leave your vehicle with the engine
running while in gear.
If you must leave
your veh icle when the engine is running,
apply the park ing brake firmly and move
the selector lever to P.
- Power is still transmitted to the wheels
when the engine is running at idle. To
prevent the vehicle from "c reeping ", you
must keep your foot on the brake when
the engine is running and the selector
lever is in D, Sor R or "tiptronic" mode is
selected.
- Do not press the accelerator pedal when
changing the se lector lever position
while the vehicle is stationary and the engine is running.
- Never shift into R or P while driving.
- Before driving down a steep slope, re-
duce your speed and shift into a lower
gear with "tiptronic".
- Do not ride the brakes or press the bra ke
pedal too often or too long when driving
down a hi ll. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases braking distance or causes complete fa il·
ure of the brake system.
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it
in place with the brake pedal or parking
brake . .,..

142 Automatic tr an smis sion
- Never hold the veh icle on an incl ine with
a slipp ing clutch . The clutch opens auto­
matically when it becomes too hot from
the overload. An indicator lamp@] illu­
minates and a dr iver message appears
c!;> page 143 when the clutch is overload­
ed.
- If the engine must remain running, never
hav e any driving pos ition engaged when
che cking under the hood. Make sure the
selector lever has secure ly engaged and
is locked in P with the parking bra ke
firmly set¢
page 256. Otherwise, any
increase in engine speed may set the ve­
hicle in motion, even with the parking
brake applied.
(D Note
- When stopping on an incline, do not try
to hold the vehicle in place by pressing
the accelerator peda l while a driving gear
is selected. Th is can cause the transm is­

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. EDRs are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDRs 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 example, 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
The Electronic Stabilization Control (ESC) rein­
forces driver safety. It reduces the risk of slip ­
ping and improves driving stability. ESC de­
tects critical s ituations such as the vehicle
Intelligent technology 223
oversteering and understeering or the whee ls
spinning . The vehicle is stabilized by applying
the brakes or reducing eng ine torque . Once
the ESC is active, the indicator light
GI blinks
in the instrument cluster.
The following systems are integrated in the
ESC:
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up
when brak ing. The vehicle can sti ll be steered
even during hard braking. Apply steady pres­
sure to the brake peda l. Do not pump the ped­
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle.
Brake assist system
The brake assist system can decrease braking
distance.
It increases braking power when the
driver presses the brake peda l quickly in emer­
gency situations. You must press and hold the
brake pedal until the situation is over. In
vehicles with adaptive cruise control*, the
brake assist system is more sensitive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road conditions. This makes it easier to
start, accelerate and dr ive up hi lls.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other wheels.
This function is not available at higher speeds .
