sensor AUDI Q7 2012 Owner´s Manual

-Prior to using a car wash, the windshield
wiper system must be switched
off (lever
i n position 0) . This helps to prevent unin ­
tentiona l switching on and damage to
the windshie ld w iper system .
@ Tips
-The windshield wipers are switched off
when the ignition is turned off. Activate
the w indshield w ipers after the ignit ion
i s switched back on by moving the wind­
sh ield wiper lever to any pos ition.
- Worn or dirty windshield wiper blades
cause smearing which can affect the op­
eration of the rain sensor . Check the con­
dit ion of yo ur windshield wipe r blades
regularly.
- The rain sensor is part of the interval
wiping system. Turning
off the ignition
will a lso deact ivate the rain sensor. To re­
activate the sensor, sw itch
off the inter­
va l w iping function, then switch it back
on again.
- Make sure the washer fluid reservoir in
the engine compartment is topped
off
before going on a long trip . Look up
c:;, page 2 73 for checking and fi lling the
washer container.
Rear window wiper
The wiper lever is also used to operate the
rear window wiper and the automatic wiper/
washer function.
Fig. 66 Wiper lever: activati ng th e rear window w iper
and washer
The rear window wiper and the automatic wip­
er/washer functions are activated as follows:

Intermittent wiping
.,. Push the wiper lever forward to the first po­
sition @
c:;, fig. 66. Th e rear window wiper
w ill wipe the window approx. every four sec­
onds.
Automatic wiper /washer function
.,. Push the wiper lever fo rward to the second
stop,
position (J) , and hold it there for as
long as you want the rear wiper/washer to
operate.
.,. Release the lever again. the wiper will keep
running for approx. four seconds.
Switching intermittent wiper action off
.,. Pull the lever all the way back to the origi-
nal position .
As soon as the reverse gear is engaged and
the front w ipers are turned on and operating
at the same time, the rear w iper also turns on
automatically.
A WARNING
Wiper blades are crucial for safe driving!
Only in good condit ion are they able to
clear the w indows properly to provide un­
restricted visib ility. Worn or frayed w iper
blades are a safety hazard!
c:;, page 66,
Replacing windshield wiper blades
(D Note
In freezing or near freezing conditions:
- Always check that the w iper b lades are
not frozen to the g lass before you turn
the wiper on. Loosen a wiper blade which
is frozen in place before operat ing the
w iper to prevent damage to the wiper
blade or the wiper motor.
- Do not use the w iper to clear a frosted
w indow . Us ing the wipers as a conven­
ient ice scrape r will destroy the wiper
blades.

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 a ir recirculation ON to p revent polluted
outside air from enteri ng the veh icle inter ior.
If the
a ir qu ality sensor l ocated in the air con­
ditioning system detects polluted outs ide a ir,
the sensor dec ides whether the air pollut ion
can be reduced by the facto ry-installed pollu­
ta nt fi lter or whethe r it is necessary to switc h
to air recirc ulation. With heavy conce ntra ti ons
of pollu tants, the a ir condit ion ing system is
switched automatica lly to recirc ulation mode
and the supp ly 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 aga in.
In the event that the windows fog up during
automat ic air rec irculat ion, you must press
the® button immediately.
Under certa in ope rating cond itions, a utomatic
air recirculation is switched off automatica lly.
With outside temperatures be low about 50 °F
(+10 °C), automatic air rec irculat ion is limited
to 30 seconds. W it h outside temperatures be­
low about 30 °F ( -1 °C) a nd with the air condi­
tione r switched off, the a utomatic air recircu­
l ation is limited to 15 seconds.
Synchronization
One climate control setting for the driver and
front passenger seats .
With synchro nization active, the driver's set­
tings a re adopted for the passenger o r vice
versa . All the othe r setti ngs that were made
are t ransferred to t he other seat . This in­
cl udes all the cl ima te co ntro l settings, excep t
for the se at heating/ven tilat ion* .
If a different setting is selected at a
"synchron ized seat ", synchronization is can­
c e lled.

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 ility Contro l (ESC) and
the Anti-Slip Regulat ion (ASR) cannot be
deact ivated when the adaptive cruise control is switched on
. If the ESC and the
Anti-Slip Reg ulation (ASR) has been de­
act ivated and you then switch on the
adaptive cru ise contro l, the ESC function
w ill also be act ivated automatically.
- Damage caused by accidents and some m inor collisions can affect the radar sen­
sor settings and cause the system to
ma lf u nction 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 su re it is free of ice
and snow. If necessary, clean the a rea
nea r the radar sensor ca refully
¢ fig. 126.
- To ensure that the radar sensor is not
bloc ked, foreig n objects (e.g. s tickers,
larger license plate mount s, add -on
par ts) mus t not cover the area near the
radar sensor ¢
fig. 126 . The area near
the radar sensor must not be pa inted, ei­
ther.

How does adaptive cruise control work?
Applies to vehicles : wit h adaptive c ruise contro l
Vehicles traveling ahead are detected with
the aid of a radar sensor .
Fig. 1 27 Bas ic pri ncip le d iag ram : Radar sensor meas ­
urement range
Adaptive cruise control uses a rada r senso r in
t h e front of the vehicle ¢
fig. 12 7. The system
has limitat ions ¢
page 125. Things that are
not moving in your lane and in your direction
of travel will not be detected. The sensor
measures the distance to reflect ive surfaces ..,.

that must have a certain size. The system re­
sponds only after the distance measurement has been made. If a measurement is not pos­
sible, the system cannot respond and w ill not
react to a vehicle or someth ing else up ahead.
Open road
When the road is clear, the adaptive cruise
contro l works like cr uise control. It maintains
a constant target speed specified by the driv­
er.
Driving in traff ic
If a slowe r vehicle driving ahead is detec ted,
the adaptive cruise contro l decelerates (within
the limits of the system)

to its speed and after adjust ing,
tr ies to maintain the set distance from the ve­
h icle ahead. The vehicle may temporarily drive
slower than the set speed while adjust ing
¢ & in Description on page 113 .
If the vehicle in front accelerates, adaptive
cruise control also accelerates up to the speed
that you have set.
If the vehicle ahead slows to a stop, ACC will
slow your 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 c ontrol!
appears in the instr ument
cluster display . Once the veh icle stops, you
must depress the brake pedal to prevent the
vehicle from moving forward or "creeping". Depressing the brake pedal turns
off ACC.
When the veh icle ahead accelerates you can
reactivate ACC
¢ page 118, as soon as your
ve hicle has reached a speed of 1 mph (2 km/
h) .
Situ ation s re quiring dri ver int ervention
In some s ituations you w ill have to use the
footbrake to s low the vehicle down in order to
keep 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 124.
Ada pti ve crui se control 115
Passing another vehicle
If you move in to the passing lane and no ve hi­
cle is detected ahead, the adaptive 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 istance
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 driver .
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 interfe 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 .
- On ly use floor mats that keep the area
around the peda ls free and that can be
securely fastened to the footwell .

System limitations
General information
Applies to vehicles: with adaptive cruise control
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 s ight distance . In some situations ACC
may react unusually or late from the driver's
point of v iew. Therefore, a lways be attent ive
to what is happening around you and always be ready to intervene, if necessary:
- when driving around curves ¢page 125
- when vehicles up front are not in line with
you r vehicle ¢ page 125
- when other vehicles are changing lanes
¢ page 126
- when other vehicles are difficult to detect
¢ page 126
- when vehicles up ahead are not moving or
obstacles are in your travel lane ¢page 126
A WARNING
The radar sensor's function and ra nge can
be reduced by rain , snow and heavy spray.
Moving veh icles up ahead may not be
prompt ly detected or may not be detected
at all.
- Always pay ca reful attention to the traf­
fic s ituation and be ready to intervene
and be rea dy to take comp lete cont rol
whenever necessary.

den by depressing the ac ce lera tor pedal.
Leaving a curv e
At the end of very long curves, ACC's predic­
tive lane reading can cause ACC to react to an­
other vehicle in the next lane and apply the
brakes on your vehicle~ fig . 140. The braking
action can be overr idden by depressing the ac­
ce le rator pedal.
Vehicles offset to one side

Vehicles that are difficult to detect
Applies to vehicles: with adaptive cruise control
Fig . 143 Two-wheeled vehicle driving ahead
Some vehicles moving up ahead in your lane
of travel are difficult to detect, for example
two-wheeled vehicles, vehicles with high

Audi braking guard
Description
Applies to vehicles: with adaptive cruise control
Audi braking guard warns you of a possible
collision with a moving vehicle up ahead.
Fig . 146 D isplay in the instrument cluste r

The Audi braking guard is active from a speed
of approx. 20 mph (30 km/h) and works with­
in the system limits
¢ page 125 even when
the adaptive cruise contro l is deact ivated.
A radar senso r is bui lt into the front of the ve­
hicle
¢ page 114, fig. 127. 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 measurement has been taken, the
system can recognize a poss ibly hazardous sit ­
uation, for example, when a vehicle up ahead
in your lane of travel suddenly brakes or when
your ow n ve hicle is moving at high speed to­
wards a much s lowe r vehicle up ahead . As
soon as the system senses that a possible co l­
l ision with the vehicle up ahead can only be
avoided by immediate full brake appl ication or
by an avoidance maneuver, a warning appears .
The system has a defau lt response time to be
ab le to sig na l befo re a col lision occu rs. This
system response time is a utomat ica lly re­
d uced if you acce lerate actively, for example
to join a highway. Braking, transverse acce ler­
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.
The system can make yo u aware of two differ­
ent hazardo us situations:
Distance
The distance warn ing is g iven if the sys tem
calc ulates that the re is not enough d istance
to the vehicle up ahead a period of more than 5 seconds. If the distance is less than 30 feet
(9 meters) at SO mph (80 km/h), for example,
an optical d isplay comes on in the instrument
cluster
c> fig . 146.
If the vehicle ahead brakes sharply, A udi brak­
ing guard cannot help you to avoid a co llision,
even in the case of an immediate response.
Take immediate act ion to avoid the collision
and increase the distance to the vehicle up
ahead .
Adapti ve crui se control 127
Speed
If there is a much slowe r vehicle mov ing up
ahead in your lane, or if the vehicle ahead brakes sharply, the Audi brak ing guard calcu­
lates the point from which a collision can only
be avoided by f ull braking or by an avo idance
maneuver . If a warning does sound, a possible
collision with the veh icle in front can only be
avo ided through an evas ive maneuver or by
braking.
The warning is given in two stages:
- Pre-warnin g: A visua l display appears in the
instrument cluster and a warning tone
sounds.
- Acute w arning : If you do not respond to the
pre-warning, 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 assistant
i=> page 114 also helps you benefit from maxi­
mum brak ing eff ic iency.
_& WARNING
Inattention can cause collisions, other ac­
cidents and ser ious personal inju ries.
- Always pay close attent ion to the traffic,
even when the Audi braking guard is
sw itched on. The Audi braking guard pro­
vides a wa rning but does not brake the
car for you. You must app ly the brakes
yourse lf!
- Always keep the safe and lega l distance
between yo ur vehicle and vehicles up
ahead.
- Aud i brak ing g uard wor ks within lim its
and will no t respond outside the system
limits, fo r example when approach ing a
stopped vehicle or stationary obstacle (end of a traffic jam or vehicle that has
broken down in traffic).
- Always remember that the radar sensor
for the Audi braking guard works within
defined detect ion and range limits that
may prevent the proper detection of oth­
er vehicles .

128 Adapti ve crui se co ntrol
-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.
