2012 AUDI A8 ECU

-When not in use, to reduce fuel consump­
tion, wind noise and to guard against theft.
A WARNING
- Use of an unapproved roof rack or incor­
rect mounting of an approved roof rack
can cause the roof rack or the items at­
tached to it to fall off the roof onto the
road .
- Objects falling from the roof of a veh icle
can cause a crash and personal injury .
- Only mount the roof rack on the desig­
nated locations on the roof
c::> fig . 70 .
-The roof rack system must be installed
exactly according to the instructions pro­
vided.
- When driving w ith a roof rack system,
changes to the center of gravity and wind
resistance can change the veh icle han­
dling and lead to a collision . Always
adapt your driv ing and your speed to the
current conditions.
0 Not e
-Your vehicle warranty does not cover any
damages to the vehicle caused by using
r oof racks or mount ing structures not
approved by Audi for your vehicle. The
same applies to damage resulting from
incorrect roof rack installation.
- Always check the roof rack mountings
and hardware before each trip and dur­
ing a trip to make sure everything is se­
cure ly tightened . If necessary, retighten
the mount ings and check the ent ire sys­
tem from t ime to t ime.
- After mounting a roof rack system, or
when you transport objects on the roof
of your veh icle, the height of the vehicle
i s naturally increased. Be careful when
driv ing under low br idges or in parking
garages for example. This could cause
damage to the load and even the vehicle
i tself.
- Make sure the open rear lid and the sun­
roof* do not come into contac t with the
roof rack .
Seat s an d sto rage 69
Loading the roof rack
Always distribute loads evenly. Make sure
anything on the roof rack is securely tied
down .
.. Always distribute the loads on the roof rack
even ly .
.. Always attach items to the roof rack secure-
ly before you d rive off .
The maximum permissible roof weight is
2 20
lb (100 kg ).
The roof weight is the total of
the weight of the roof rack, the attachments
and the cargo you a re carrying. You must also
not exceed the maximum load we ight for the
roof rack you are using .
When using a roof rack system which has a l ower load ca rrying capaci ty , you must not use
up the tota l maxim um permissible load car ry ­
i ng capacity specified above . Instead, you
sho uld load the roof rack system only to the
maximum capacity specified by the manufac ­
turer of the roof rack system.
A WARNING
---Weak, damaged or improper straps used
to secure items to the roof rack can fail
during hard braking or in a collis ion and
cause ser ious personal injury.
- Make sure the roof rack is installed exact­
ly as specified above
c::> page 68.
-Always use su itable mount ing straps for
securing items to the roof rack to help
p revent items from sh ifting or flying for­
ward.
- Items on the roof rack must always be
securely mounted.
- The use of a roof rack can negat ively af­
fect the way a veh icle hand les . Cargo
that is large, heavy, bulky, long or flat
will have a greater negat ive influence on
the vehicle's aerodynamics, center of gravity and overall handling . Always
drive s lowly, avoid sudden braking and
maneuvers when transporting cargo on
the roof of your vehicle .

- the temperature in the luggage compart­
ment is below 131 °f (55 °C). The cooler
switches off automatically if the tempera­
ture in the luggage compartment exceeds
131 °f (55 °C) . Once the temperature falls
below 131 °f (55 °C) again, the cooler
switches on aga in automatically .
- the battery is adequately charged . The cool­
er switches off automatically if the vehicle
battery voltage falls below a minimum lev­
el. This prevents the battery from discha rg­
i ng . The cooler switches back on again auto­
matically when the battery voltage increases
again (e.g . after starting the engine).
The cooler cools to 42.8 °f
(+ 6 °C) and the
freezer cools to 21.2 °f (-6 °C) in opt imum
cooling cond itions . Th e cooling performance
is affected by the temperature in the luggage
compartment. The temperature inside the
cooler will be higher if the luggage compart­
ment is hot.
A WARNING
To avoid putting the occupants at any risk,
please observe the following safety rules:
- The maximum capacity is 2.5 kg (5.5
lbs.).
- Never overload the cooler. This could
cause injury in the event of a collision or
sudden braking.
- The coo ler lid must always be kept closed
while you are driving. Make sure the re­
taining catch is securely engaged. The
contents of the coo ler could be thrown
forward into the passenger compart­
ment in the event of a collision or under
sudden braking - risk of injury!
- Inflammable liquids, gas canisters, etc.
must not be stored in the cooler -risk of
exp losion! This also includes any prod­
ucts that might emit volatile or inflam­
mable gases.
- Liquids will freeze at temperatures at or
below 32 °f (0 °C) and may cause glass
bottles to burst!
Seats and storage 73
(D Note
-The venti lation openings for the cooler
are located on the back pane l trim in the
luggage compartment and
must be kept
clear at all t imes.

- Always remember that the radar sensor
for the Audi braking guard works only
within defined detection and range limits
that may prevent the proper detection of
other 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 al l.
- Reflective surfaces includ ing crash barri­
ers or tunnel entrances may impair the
func tion of the radar sensor.

- You can cancel the braking w ith increas­
i ng force that is initiated by the system
by braking yo urself, by accelerating no­
ticeab ly or by swerving.

-Passengers must always sit in an upright
position and never lean against or place
any part of their body too close to the
area where the airbags are located.
- Passengers who are unbelted, out of po­
sition or too close to the airbag can be
seriously injured by an airbag as it un­
folds with great force in the blink of an
eye.
- Always make sure that there are at least
10 inches (25 cm) between the front
passenger's breastbone and the instru­
ment panel.
- Always make sure that there are at least
4 inches (10 cm) between the front pas­
senger's knees and the lower part of the
instrument panel.
- Each passenger must always sit on a seat
of their own and properly fasten and
wear the safety belt belonging to that
seat.
- Before driving, always adjust the front
passenger seat and head restraint prop­
er ly.
- Always keep your feet on the floor in
front of the seat. Never rest them on the
seat, instrument panel, out of the win­
dow, etc. The airbag system and safety
belt will not be able to protect you prop­
erly and can even increase the risk of in­
jury in a crash .
- Never drive with the backrest reclined or
tilted far back! The farther the backrests are tilted back, the greater the risk of in­
jury due to incorrect positioning of the
safety belt and improper seating posi­
tion.
- Children must always ride in child seats

when installing a child seat on the front
passenger seat¢

Driving Safely 127
Proper seating positions for passengers
in rear seats
Rear seat passengers must sit upright with
both feet on the floor consistent with their
physical size and be properly restrained
whenever the vehicle is in use.
To reduce the risk of injury caused by an incor­
rect seating position in the event of a sudden
braking maneuver or an accident, your pas­
sengers on the rear bench seat must always
observe the following:
.,. Adjust the head restraint so the upper edge
is as even as possible with the top of your
head. If that is not possible, try to adjust
the head restraint so that it is as close to
this position as possible¢
page 128 .
.,. Keep both feet flat in the footwell in front
of the rear seat.
.,. Fasten and wear safety belts properly
¢page 137.
.,. Make sure that children are always properly
restrained in a child restraint that is appro­
priate for their size and age
r::, page 166.
,& WARNING
..-
Passengers who are improperly seated on
the rear seat can be seriously injured in a
crash.
- Each passenger must always sit on a seat
of their own and properly fasten and
wear the safety belt belonging to that seat.
- Safety belts only offer maximum protec­
tion when the safety belts are properly
positioned on the body and securely
latched . By not sitting upright, a rear
seat passenger increases the risk of per­
sonal injury from improperly positioned
safety belts!
- Always adjust the head restraint properly
so that it can give maximum protection.
