2012 AUDI Q7 Owner´s Manual

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.

fig. 147 to help the driver check
b lind spots, and see what is happen ing in traf ­
fic beh ind the veh icle
¢ page 130, fig. 150.
Signal lights are bu ilt into both outside m ir­
r ors ¢
fig. 148. The signal light on the left
outside mirror assists when moving over into
the left lane and the signal light on the r igh t
ou tside mirror assists when moving over in to
the right lane .
The s ignal light comes on to tell you that side
assis t has detec ted a vehicle on tha t side and
that t he position of this othe r vehicle should
be taken into account if yo u were to change
lanes . This is called the
informatio nal st age
sign al¢
page 131. The informat ional stage
Aud i side assist 129
signal is designed so that you notice it on ly
when you are looking in the outside mirror.
When yo u activate the turn signal and side as ­
s ist de tects a vehicle in a no table location, the
corresponding signal on the outside mi rror
flashes briefly and brightly several times. This
is the
a lert stage signal ¢ page 131 .

A WARNING
-Imp roper reliance on the side assist sys­
tem can cause collis ions and serio us pe r­
sonal injury:
- Never rely on ly on side assist when
changing lanes.
- Always check rear view mirrors to make
su re that it is safe to change lanes.
- Side assist canno t detect all veh icles un ­
de r all conditions- danger of accident!
- Side assist cannot detect vehicles in time
to a lert you w hen they app roac h from
behind at very hig h speed, or fall drop
back very qu ickly.
~

130 Audi side assist
-The radar sensor's vision can be reduced
or entirely blocked by rain, snow, and
heavy spray . This can result in side assist
not adequately detecting vehicles or, in
some cases, not detecting them at all.
Always keep an eye on the direction you
are traveling and the relevant area
around the vehicle.
- Please note that side assist indicates
there are approaching vehicles, or vehi­ cles in your blind spot, only after your ve­
hicle has reached a driving speed of at
least 19 mph (30 km/h).
- Side assist signal does not work around
tight corners (turning radius less than
328 feet, or 100 m).
- Side assist is no replacement for the driv­
er's full attention. The driver alone is re­
sponsible for lane changes and similar
driving maneuvers. Always keep an eye
on the direction you are traveling and the relevant area around the vehicle.
- To ensure that you do not adversely af­
fect side assist, do not block the area on
the rear bumper where the radar sensors
are located with foreign objects (such as
stickers or bicycle racks).
- Make sure that the signal light on the
outside mirror is not blocked by stickers
or other items.
(Di Tips
- Side assist automatically deactivates if it
detects that the radar sensors are
blocked ¢
page 135. The indicator light
on the button goes out .
- The area on the bumper where the radar
sensors are located must consistently re­
main free of snow, ice, and heavy soiling
so that side assist can function properly.
Follow the additional notes on
¢page 136.
-For vehicles with a factory installed tow­
ing hitch* or a trailer hitch* that was in­
stalled later according to factory specifi­
cations, side assist is automatically deac- tivated
as soon as the electrical connec­
tion to the trailer electrical socket is made
¢ page 135.
-For vehicles with a trailer hitch that was
not installed according to factory specifi­
cations, switch off the side assist when
towing a trailer .
- Additional tinting on the front side win­
dows can make it harder to see and cor­
rectly understand the signal light on the
outside mirror.

ill b''T -
Fig. 150 Sc hematic illustration: Sensor detectio n area
The detection ¢ fig. 150 of the radar sensor
detection area is made up of:
-
- the approach area (light red area) (D, about
230 feet (70 m) behind the vehicle, and
- the "blind spot" (dark red area) @.
The radar sensors cover the adjacent left and
right lanes. Other lanes are
not covered by the
radar sensors.
(D Tips
Side assist does not measure actual lane
width. The system assumes a fixed lane
width . Detection in the left and right lanes
is based on this assumed lane width.
When driving on narrow roads or when
driving to the left or right of the center of
a travel lane, it is possible that vehicles
will be detected that are
not in the lane

next to the lane you are using
¢page 135.
Operation
Applies to vehicles: with side assist
Side assist compares the distance and differ­
ence in speed of detected vehicles with the
speed of your vehicle . Whenever the differ­
ence in speed and d istance is registered as no­
table if you were to change lanes, a signal l ight appea rs on the respective mirror.
The signal can light up if you are passed by a
vehicle or if you are pass ing another vehicle.
If you pass another vehicle s lowly (difference
in speed less than 9 mph, or 15 km/h), the
signal light will come on as soon as the other
vehicle is in your blind spot and is detected by
side assist . When the difference in speed is
g reater, the signal light will not come on.
Informational and alert stage signals
Applies to vehicles: with side assist
Side assist has two signal stages:
- the informational stage signal, and
- the alert stage signal.
Side assist he lps you by using the appropriate
signal stage, depending on whether or not
you have activated the turn signal, and thus have indicated that you are or are not chang­
in g lanes .
Informational stage signal
As long as you have not activated the turn sig­
nal, side assist informs you of detected vehi­
cles that are registered as being in a notable locat ion if you were to change lanes. Whenev­
er the detected vehicle's difference i n speed
and distance is registered by side assist as no­
table, the signal light on the respective m irror
produces muted illuminat ion.
The br ightness of the informat ional stage sig ­
nal is designed not to be as intense, so that it
does not interfere with your view of the road
when yo u are driving and have no intention of
changing lanes. When you look i n the outside
Aud i side assist 131
mirror, you can clearly see the informational
stage signal.
Alert stage signal
When you activate the turn signal, and s ide
ass ist has detected a vehicle in a notable loca­
t ion on that part icular s ide, the signa l light on
this side mirror flashes brightly. The repeated
brief and bright flashing of the alert stage
signal reminds you to carefully check traffic to
the rear in the outside mirror and over your
shoulder, so that you can safely complete the lane change
