Automatic recirculation mode '
An air quality sensor detects increased con­
centrations of pollutants in the outside air
and automatically switches to recirculation
mode .
We recommend that you always keep auto ­
matic air recirculation ON to prevent polluted
outside air from entering the vehicle interior.
If the
air quality sensor located in the air con­
ditioning system detects polluted outside air,
the sensor decides whether the air pollution
can be reduced by the factory-installed pollu­
tant filter or whether it is necessary to switch
to air recirculation. With heavy concentrations
of pollutants, the air conditioning system is
switched automatically to recirculation mode
and the supply of outside air is blocked. As
soon as the concentration of pollutants in the
outside air drops, fresh air is supplied to the
vehicle interior again.
In the event that the windows fog up during
automatic air recirculation, you must press
the® button immediately .
Under certain operating conditions, automatic
air recirculation is switched off automatically.
With outside temperatures below about SO °F
(+10 °(), automatic air recirculation is limited
to 30 seconds. With outside temperatures be­ low about 30 °F
( - 1 °() and with the air condi ­
tioner switched off, the automatic air recircu­ lation is limited to 15 seconds.
Synchronization
One climate control setting for the driver and
front passenger seats .
With synchronization active, the driver's set­
tings are adopted for the passenger or vice
versa. All the other settings that were made
are transferred to the other seat . This in­
cludes all the climate control settings, except
for the seat heating/ventilation* .
If a different setting is selected at a
"synchronized seat ", synchronization is can­
celled.

brake and take evasive action to avoid
collisions and other accident situations.
- Never allow the closing speed between
you and other vehicles to be so high that
the adaptive cruise control may not be
able to slow your vehicle safely. If clos­
ing speed is too high, you must apply the
brakes yourself to reduce the risk of a
rear-end crash .
- Never rest your foot on the accelerator peda l, especia lly when the adaptive
cruise control is be ing used. Pressu re on
the accelerator w ill override the ACC
braking function and prevent the brakes
from being applied when ACC detects a situation when the brakes must be ap­
plied.
- Never use adaptive cruise contro l when
you cannot drive safe ly at a steady
speed, including on city streets, on wind­
ing roads or when road conditions are
poor (for example, on ice, gravel, in fog,
heavy rain or on wet roads that increase
the risk of hydroplaning) .
- The radar sensor 's
vision can be reduced
by rain, snow and heavy road spray .
T hese and sim ilar condit ions can prevent
vehicles up a head from being accurately
detected and in some cases they may not
be detected at al l. Do not use ACC when
the radar sensors cannot accurately de­
tect vehicles moving ahead of yo u in traf­
fic .
- Always turn off adaptive cruise contro l
when entering turn lanes , exit lanes and
construction zones or in similar situa­
t ions because the vehicle will automati­
cally accelerate to the stored speed when
the road ahead is clear.
- To prevent unintended operation, always
switch ACC off when it is not be ing used .
(D Tips
-For safety reasons, the stored speed is
deleted when the ignition is turned off .
- The E lectronic Stab ilizat ion Control (ESC)
i s automatically turned on when the
adaptive cruise control is turned on. You cannot switch the ESC into offroad mode

-Damage caused by accidents and some
mino r collisions can affect the radar sen­
sor settings and cause the system to
malf unction or switch off completely.
- The radar sensor cover is heated. In win ­
ter conditions, you should st ill check be­
fore dr iv ing to make sure it is free of ice
and snow. If necessary, clean the area
near the radar sensor carefully

sib le, the system cannot respond and wi ll not
react to a vehicle or someth ing else up ahead .
Open road
When the road is clear , the adaptive cru ise
control wo rks like cruise control.
It maintains
a constant target speed specified by the driv­
er.
Driving in traff ic
If a slower vehicle d riving ahead is detected,

to its speed and after adjusting,
tr ies to maintain the set distance from the ve­
h icle ahead. The vehicle may temporarily drive
slower than the set speed while adjusting
¢ .&. in Description on page 115 .
If the vehicle in front accelerates, adaptive
cru ise control also accelerates up to the speed
that you have set.
I f the vehicle ahead slows to a stop, ACC will
slow yo ur vehicle down and to a complete
stop if this is possible w ith in the system's lim­
its and capabilities. ACC will not make an
emergency stop . The text message
ACC off:
manual control! appears in the instrument
cluster display. Once the veh icle stops, you
must dep ress the brake pedal to prevent the
veh icle from mov ing forward or "creeping" .
D epressing the brake pedal turns
off ACC.
When the vehicle ahead accelerates yo u can
reactivate ACC
¢ page 120, as soon as your
vehicle has reached a speed of 1 mph (2 km/
h) .
Situat ion s requiring dri ver int ervention
In some situations you wi ll have to use the
footbrake to s low the vehicle down in order to
k eep a safe distance from vehicle in front of
you or to avo id a rear -end coll is ion. In this sit­
uation, a symbol appears and a warning tone
sounds ¢
page 126 .
Adapti ve crui se control 117
Passing another vehicle
If you move into the passing lane and no ve hi­
cle is detected ahead , the adapt ive cr uise con­
trol acce le rates to the speed you have set and
maintains it.
Overr iding ACC
You can in cr ease yo ur speed at a ny time by
stepping on the accelera tor ped al. A fter you
release the accelerator peda l, the system ad­
justs back down to the speed you prev ious ly
set .
Reducing stopp ing distance
If the radar sensor detects that the d istan ce
to the vehicle a head is less than de fined m ini­
mum distance, the brakes are automatically
prepared fo r emergency braking by the d river .
The brake pads are moved very close to the brake d iscs without actually braking the vehi­
cle. This brake assistant feature reacts more
quick ly to the dr ive r's brak ing, and also works
when adapt ive cruise control is
off . The stop­
ping distance is reduced as a result of th is ad­
vance brake p reparation . Th is fun ction does
not perform any emergency b rak ing mane u­
vers by itse lf; the dr iver mus t always apply the
brakes.
A WARNING
If ACC initiates a braking maneuver, the brake pedal w ill be retracted. Inter ference
with the brake peda l can prevent ACC from
slowing the veh icle down and cause a
crash and serious personal injury.
- Never put anything in the driver's foot­
well or let anyth ing fall into it. An object
in the driver's footwe ll can inte rfe re with
the peda ls and prevent the acce le rator
from being used to override ACC or pre­
vent ACC from being switched
off when
the brake pedal is depressed and also
prevent the vehicle from being slowed
down or stopped .
- Onl y use floor mats that keep the area
aroun d the peda ls free and that can be
securely fastened to the footwell .

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 .
