AMI AUDI Q7 2012 Owner´s Manual

Rearv iew cam era c overage a rea
The MM I display shows the area covered by
the rearview camera c:>
fig. 166 (!). Objects
that are not in the area covered @are not
shown on the MMI display .
We recommend that yo u practice parking with
the rearview camera in a traffic-free location
or parking lot to become familiar with the sys ­
tem, the orientation lines, and their function.
When do ing th is, there should be good light
and weather conditions.
I n the MMI disp lay, objects or vehicles appear
closer or further away if:
- you are driving in reverse gear from a level
s u rface onto an incline, or a downward
s lope,
- you are driving in reverse gear toward pro ­
truding objects,
- the vehicle is carrying too much load in the
rear .
The accuracy of the or ientat ion lines and blue
surfaces dimin ishes if:
- the Adaptive A ir Suspension* is faulty or the
dynamic, offroad or lift mode is on,
- the rearv iew camera does not provide a reli­
able image, for example, in poor visibility
cond it ions or if the lens is dirty,
- the image on the screen is not visible due to sun glare and reflection.
Ca ring for the rear view c amer a len s
The rearview camera is located above the rear
license plate bracket . For the parking system
to operate, the lens
c:> fig. 167 must be kept
clean:
- Dampen the lens with a househo ld alcoho l­
based glass cleaner, and then wipe the lens
clean with a dry cloth c:>0 .
- Remove snow with a hand brush and ice
preferably with a de-icing spray
c:> ([).
A WARNING
-The parking system cannot rep lace the
dr iver's attention. The driver alone is re-
-
Par king system 145
sponsib le for parking and simi lar d riving
maneuvers.
- Sensors have blind spots in which objects
cannot be detected. Pay spec ia l attention
to small children and an imals because
the sensors cannot always detect them.
-Always keep your eyes on the vehicle's surroundings, us ing the rearview mirror
as well.
- Do not allow yourself to be distracted
from traffic by the rearv iew camera pic­
tures .
- If the position and the installation angle
of the camera has changed, for example,
after a rear end collision, do not continue
to use the system for safety reasons.
H ave it checked by a qualified dea le rship.
(D Note
- Low obstacles a lready s ignaled by a
warning can disappear from the system's
detect ion range as they are approached
and w ill not continue to be s ignaled. Ob­
jects such as ba rr ie r chains, trai le r d raw
bars, thin painted vert ica l poles or fen­
ces may not be detected by the system,
posing r isk of damage .
- Never use warm or hot wate r to remove
snow or ice from the rearview camera
lens -this could cause the lens to crack!
- When cleaning the lens, never use prod ­
ucts that are ab rasive.

150 Adapti ve Air Susp en sion
Adaptive Air
Suspension
Air suspension and damping
Description
App lies to vehicles: with Adapt ive Air Suspe nsion
Air suspension and damping can be adjusted
separately.
Adaptive Air Suspension is an electronically
controlled springing and damping system .
This chassis system makes it easier on the
driver by adapt ing to the particular situat ion
through imperceptible control processes.
The
Ad apti ve Air Su sp ension component reg ­
ulates ground clearance depending on vehicle
speed and driver input. It functions independ­
ently from the load condition . Accelerating to
a speed above a predetermined limit will make the vehicle lower itself . On the other
hand, driving more slowly results in the vehi­
cle raising aga in at specific speeds.
The
d am ping component provides individual
control of the damping forces. For example,
with damping characterist ics set to prov ide
greater comfort, damping is set somewhat
harder for a brief per iod only as required, for
example, when going around a curve or when brak ing .
Set tings
Adapt ive A ir Suspension provides the driver
with the opportun ity to set the chassis charac­
teristics also to their individual prefe rence.
W ith the dr iv ing modes
Comfort, Automatic
and Dynamic the driver has three chassis set ­
tings available, ranging from comfort to spor­
ty. The
Offrood mode can be selected for driv­
ing on poor quality stretches of road. In addi­
tion,
Lift provides a fifth mode, which can be
selected when exceptionally high ground
clearance is needed
c::> page 150, Chassis con ­
trols.
The modes are set in MMI r:::;, poge 152.
A WARNING
The height of the parked vehicle can
change due to temperature fluctuations or
changes in load.
([) Note
- Whenever you park your vehicle, a lways
make sure there is adequate clearance
above and below the vehicle. The he ight
of the parked vehicle can change as the
result of temperature f luctuations,
changes in load cond ition and changes in
the driving mode (ground clearance).
- If the vehicle is being t ransported (e.g.
by tow truck, train, sh ip, etc.), mount the
tie-down chains/cables over the running
surface (circumference) of the tires. Nev­
er secure the vehicle by the axle, the sus­
pension struts or the front or rear tow­
line eye. For technical reasons, the pres­
sure in the suspens ion struts may change
during the transport, which could result
in the vehicle no longer be ing secured
properly .
- If you are going to tow a trailer with a trailer hitch that was
not installed ac­
cording to factory specif ications, you
must activate the tra iler operation mode
manually
c;, page 154.
(D Tips
- Before you can raise your vehicle us ing
the vehicle jack (for example, when
changing a f lat t ire) or a veh icle lift, yo u
must activate the jac king mode
c::>poge 154.
-On some mode ls, the vehicle can reach
its maxim um speed only in the
Automat ­
ic
and Dynamic modes.
Chassis controls
Applies to vehicles: wit h Adaptive A ir Suspensio n
Five different driving modes con be set by the
driver.
The automatic control processes are speed­
and t ime -dependent . Fo r example, it is not

possible to raise the suspension to a high leve l
above certain speeds .
When a speed of about 75 mph (120 km/h) is
exceeded for more than 30 seconds, the vehi­
cle is automatically lowe red to
low level when
in comfort and automatic mode. Ground
clearance is about 0.6 inch (15 mm) less,
compared to the
normal level.
When a speed of about 100 mph (160 km/h)
is exceeded for more than 20 seconds , the ve­
h icle is automat ica lly lowered to
highway lev­
el
when in automatic and dynamic mode.
Ground clearance is about 1.4 inches (35 mm)
less, compared to the
normal level. Road
holding is opt imized as a result of the lower
center of gravity, and fuel consumption is re­
duced as a result of reduced wind resistance .

Automatic
Select the automatic mode if you prefer a bal­
anced, comfortable suspension setting . The
damping characteristics are adjusted accord­
ingly.
- Automatic lowe ring: When a speed of
about 75 mph (120 km/h) is exceeded for
more than 30 seconds, the vehicle is auto­
matically lowered by about 0.6 inch (15
mm) to the
low level, wh ich is more suitable
for highway speeds. Road hold ing is opti ­
mized as a result of the lower center of grav-

ity and fuel consumption is reduced as a re ­
sult of reduced wind resistance . When a
speed of about 100 mph (160 km/h) is ex ­
ceeded for more than 20 seconds, the veh i­
cle is automatically lowered by an addit ional
0 .8 inch (20 mm) to
highway level.
- Automat ic raising: When the vehicle is at
highway level and the speed falls below
about 80 mph (130 km/h) for more than 20
seconds, the vehicle is automatically raised
to
low level. T he ve hicle is automat ica lly
ra ised aga in to
normal level if the speed
fa lls below abo ut 44 mph (70 km/h) for a
period of 2 minutes . The vehicle is raised im ­
mediately when speed fa lls below abo ut 22
mph (35 km/h).
Dynamic
Se lect the dynamic mode if you prefer a spo r­
ty suspension setting. In t his mo de, the veh i­
cle is lowered to
low level while it is still sta­
tionary and sporty damping characteristics
are se lected . The warning light
Ill in the in­
strument cl uster will come on for a few sec­
onds just to rem ind you of the reduced ground
clearance .
If you switc h off the engine whi le the vehicle
is in the dynamic mode and then switch on the
ignition once aga in, the
Ill warning light will
also come on aga in for a few seconds as a re­
minder .

mu st be se lect­
ed so that the ve hicle can be at normal level
¢ page 152, MMI settings .
-If driving in dynamic mode is desired, this
mode
mu st be selected before hitching up
the trailer and before ad justing the tongue
weight. However, note that your vehicle is lowered and ground clearance is reduced.
- If you have to drive under difficult road con­
ditions, you can select offroad or lift mode,
after hitching up the trailer or after adjust­ ing the tongue weight .
- If the veh icle is at
normal level, and you se­
lect offroad mode wh ile traveling at speeds
higher than 22 mph (35 km/h), the veh icle
w ill not be ra ised . Offroad mode will appear
as the active mode in the MM I Disp lay.
- If the veh icle is in offroad mode at

Rest rictions when ope rating with a tr ailer
When operating w ith a trailer, the lift mode
can on ly be selected up to about 12 mph (20
km/h). Lift mode is automatically cance led
again w hen a speed of about 25 mph (40 km/
h) is exceeded.
If t he vehicle is in au toma tic , comfo rt, offroad
or lift mode before the trai ler towing mode is
activated, the dynamic mode cannot be acti­
vated.
If t he vehicle is in dynamic mode before tow -
ing opera tion is activated, it can be driven in

this mode. If the suspension is switched from
this mode to another mode, dynamic mode
cannot be re-se lected .
{D) Tips
-For vehicles with a factory installed tow­
ing hitch or a trailer hitch that was in­
stalled later accord ing to factory specifi­
cations, the system recognizes "Trailer
tow ing mode" and activates this special
mode automatically, as soon as the elec­
trical connection on the trailer socket is
connected . The mode ceases automat i­
cally when the elect rical connection to
the trailer socket is d isconnected.
- If the tra iler towing mode has been act i­
vated, the vehicle will not drop to the l ow or highway level.

Stowing luggage
Loading the luggage compartment
All luggage and other objects must be prop­ erly stowed and secured in the luggage com ­
partment.
Fig . 184 Safe load pos ition ing: place heavy objects as
low and as far forward as possible.
Loose items in the luggage compartment can
shift suddenly, changing vehicle handling
characterist ics . Loose items can also increase
the r isk of serious personal injury in a sudden
vehicle maneuver or in a collision .
,. Distribute the load evenly in the luggage
compartment .
,. Always place and properly secure heavy
items in the luggage compartment as low
and as far forward as poss ible
¢fig. 184.
,. Secure luggage using the tie-downs provid­
ed
¢ page 80.
,. Make sure that the rear seatback is securely
latched in place .
A WARNING
Improperly stored luggage or other items
can fly through the vehicle caus ing serious
personal inj ury in the event of hard brak­
ing or an acc ident. To help reduce the r isk
of serious persona l injury:
- Always put objects, for example, luggage
or other heavy items in the luggage com­
partment.
- Always secu re objects in the luggage
compartment us ing the tie-down eye lets
and suitable straps.
A WARNING
-Heavy loads wi ll influence the way your ve-
h icle ha ndles. To help reduce the risk of a
loss of control leading to serious personal
i njury:
-Always keep in mind when transporting
heavy objects, that a change in the cen­
ter of gravity can also cause changes in
veh icle handling:
- Always distribute the load as evenly as
poss ible.
- Place heavy objects as far forward in
the luggage compartment as possible.
- Never exceed the Gross Axle We ight Rat­
ing or the Gross Vehicle Weight Rating
specif ied on the safety compliance stick­
er on the left door jamb. Exceed ing per­
miss ible weight standards can cause the
veh icle to slide and handle differen tly.
- Please observe information on safe dr iv­
ing
¢page 160.
A WARNING
-
To help prevent poisonous exhaust gas
from being drawn into the vehicle, a lways
keep the rear lid closed while driving.
- Never transport objects larger than those fitting comp letely into the luggage
area because the rear lid cannot be ful ly
closed.
- If you absolutely m ust dr ive wi th the rear
lid open, observe the following notes to
red uce the risk of poisoning:
- Close all windows,
- Close the Panoramic sliding sunroof *,
- Open all air outlets in the instrument pane l,
- Switc h off the air recirculat ion,
- Set the fresh air fan to the highest
speed.

Improperly worn safety belts
Incorrectly positioned safety belts can cause
severe injuries .
Wearing safety belts improperly can cause se­
rious injury or death. Safety belts can only
work when they are correctly positioned on the body . Improper seating positions reduce
the effectiveness of safety belts and will even increase the risk of injury and death by mov­
ing the safety belt to critical areas of the
body . Improper seating positions also in­
crease the risk of serious injury and death
when an airbag deploys and strikes an occu­
pant who is not in the correct seating posi­
tion . A driver is responsible for the safety of
all vehicle occupants and especially for chil­
dren . Therefore:
... Never permit anyone to assume an incorrect
sitting position in the vehicle while traveling
¢ ,& .
A WARNING
Improperly worn safety belts increase the
risk of serious personal injury and death
whenever a vehicle is being used.
- Always make sure that all vehicle occu­
pants are correctly restrained and stay in
a correct seating posit ion whenever the
vehicle is be ing used.
- Always read and heed all WARNINGS and
other important information

Safety belt preten­
sioners
How safety belt pretensioners work
In front, side and rear -end collisions above a
particular severity and in a rollover, safety
belts are tensioned automatically.
The safety belts are equipped with safety belt
pretensioners . The system is activated by sen­
sors in front, side and rear-end collisions of
great severity and in a rollover. This tightens
the belt and takes up be lt sla ck

page 178.
Taking up the slack helps to reduce
forward occupant movement dur ing a colli­
sion.
@ Note
Never let the belt remain over a rear seat­
back that has been fo lded forward.
(D Tips
The safety belt pretensioner can only be
activated once.
- In minor frontal and side collisions, in
rear-end collisions and in accidents in­
volving very little impact force, the safe­
ty belt pretensioner are not activated.
- When the safety belt pretensioners are
activated, a fine dust is re leased. This is
normal and is not caused by a fire in the
vehicle.
- The re levant safety requirements must
be observed when the vehicle or compo­
nents of the system are scrapped. An au­
thorized Audi dealer or qualified work­
shop is familiar w ith these regulations
and w ill be pleased to pass on the infor­
mation to you.
- Be sure to observe all safety, environ­
menta l and other regulations if the veh i­
cle or ind ividual parts of the system, par­
ticularly the safety belt or airbag, are to
be disposed. We recommend you have
your authorized Audi dealer perform this
service for you.
Service and disposal of safety belt
pretensioner
The safety belt pretens ioners are parts of the
safety belts on your Audi. Insta lling, remov­
ing, servic ing or repair ing of belt pretension­
ers can damage the safety belt system and
prevent it from working correctly in a colli­
s ion .

.&_ WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing a safety belt
pretensioner from activating when needed
or activating it unexpectedly:
- The belt pretensioner system can be acti­
vated only once . If belt pretensioners
have been activated, the system must be
replaced.
- Never repair, adjust, or change any parts
of the safety belt system.
- Safety belt systems including safety belt
pretensioners cannot be repaired. Spe­
cial procedures are required for removal,
installation and disposal of this system.
- For any work on the safety belt system,
we strongly recommend that you see
your authorized Audi dealer or qualified
technician who has an Audi approved re­
pair manual, training and special equip­
ment necessary.

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem pe rforms in a crash. For example, using
tire-r im combinations not app roved by Aud i,
lowe ring the vehicle, ch anging the stiffness of
the suspension, incl uding the springs, s uspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the ai rbag
sensors and sent to the electronic control
un it. Some suspension changes can, for exam­
p le, increase the force levels measured by t he
sensors and make the airbag system deploy in
crashes in wh ich it would not dep loy if the
cha nges had not been made. Other k inds of
cha nges may reduce the force levels meas­
ure d by the sensors and preven t the a irbag
from deploying when it sho uld .
The senso rs in the safety belt buckle fo r th e
d river and front passe nger sea t tell the elec­
tronic control module if the safety belt is
l atched or not. I f the safety belt is being used,
the front airbag will deploy at a slightly high­ er rate of vehicle deceleration than if the safe­
ty belt is not being used. Therefore, in a par­
ticular collision, it is poss ible that an airbag
will not deploy at a seating position where the safety belt is being used but will inflate at the position where t
he safety be lt is not being
used. It is important that nothing interfere
with the safety be lt b uckles so that the sen­
sors can send the correct information about
safety belt use to the electronic control un it.
A WARNING
=
Changi ng the veh icle's suspension includ-
i ng use of unapp roved tire-rim combina­
tions can change Advanced Airbag per­
fo rma nce and increase the r is k of seri ous
personal injury in a cra sh.
- N ever install suspension components
that do no t have the same pe rformance
chara cter istics as the compone nts o rigi­
na lly ins talled on your vehicle .
- Never use tire-rim combinations that
have not been approved by Audi.
A WARNING
= -
It ems stored between the safety be lt
bu ckle and the cente r console can cause
the sensors in the b uckle to send the
wrong information to the e lectronic con­
trol module and prevent the Advanced Air­ bag System from working prope rly.
- Always make sure that nothing can inter­
fere with the safety belt buckles and that they are not obstructed .

226 Intelligent technology
can result in there being insufficient energy
avai lab le to start the engine .
I ntell igent energy management in your vehi­
cle handles the distribution of electrical ener­
gy . Starting abi lity is markedly improved and
the life of the battery is extended .
Basically , energy management consists of
battery diagnosis , idling current manage­
ment
and dynamic energy management.
Battery diagnosis
Battery diagnosis continuously determines
the state of the battery. Sensors determine
battery volta ge, battery current and battery
temperature. This determines the current
state of charge and the power of the battery.
Idling current management
Idling current management reduces energy
consumption while the vehicle is stand ing.
With the ignition switched off, it contro ls the
energy supply to the various e lectrica l compo­
nents. Data from battery diagnosis is consid­
ered.
Depending on the battery's state of charge,
individua l consumers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability.
Dynamic energy management
While the vehicle is being dr iven , dynamic en­
e rg y management distributes the energy gen­
erated according to the needs of the individu­
a l components. It regulates consumption, so
that more ele ctrical energy is not being used
than is being generated and ensures an opti­ mal state of cha rge for the battery.
{D) Tips
- But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are
limited .
- If starting ab ility is threatened, you are
i nformed by a warn ing
c> page 22 7,
Driver notification in the instrument
cluster display .
What you should know
The highest priority is given to maintaining
starting capability .
The battery is seve rely taxed in shor t-distance
driving, in city tra ffic and dur ing the cold time
