AUDI S6 2013 Repair Manual

-Any articles of cloth ing that you have
hung up must not interfere with the driv­
er's view. The coat hooks are designed
only for lightweight clothing. Never hang
any clothing w ith hard, pointed or heavy
objects in the pockets on the coat hooks. During sudden braking or in an accident -
especially if the airbag is deployed -
these objects could injure any passen­
gers inside the vehicle.
- To reduce the r isk of personal injury in an
acc ident or sudden stop, always keep the
glove compartment closed whi le driving.
- Read and fo llow all WARN INGS
~ page 167, Important safety instruc­
tions on the side airbag system.
- Hang clothes in such a way that they do
not impair the driver's v ision .
- T he coat hooks m ust only be used for
lightwe ight clothing. Do not leave any
heavy or sharp edged objects in the pock ­
ets which may interfere with the side cur­
tain a irbag deployment and can cause
persona l injury in a crash.
- Do not use coat hangers for hanging
clothing on the coat hooks as this can in­
terfere with proper deployment of the
side curtain airbags in an accident.
- Do not hang heavy objects on the coat
hooks, as they cou ld cause personal in­
jury in a sudden stop.
- For strength-related reasons, the mount­
ing hooks can only be used to secure ob­
jects weighing up to 10 lb. (5 kg). Heavi­ er objec ts will not be adequately secured
- there is a risk of injury.

Roof rack
Description and mounting locations
Additional cargo can be carried with a roof
luggage rack.
Fi g. 61 Roof r ack attac hment points
.,. Always read and follow the instructions pro­
vided by the roof rack man ufacturer when
installing the roof rack system .
If luggage or cargo is to be carried on the
roof, yo u must observe the following:
- Only use roof racks approved for your vehi­
cle. These approved roof racks a re the basis
for a comple te roof rack system. Add it iona l
attachments or ca rr ier systems a re needed
to transport luggage and sports equipment .
We recommend using roof racks from the
Audi original accessories program.
- When installing the roof rack, make sure it
is only mounted on the designated locations
on the roof
q fig. 61 .
-We recommend that you keep the installa­
tion instructions for your roof rack system
together with your Owner's literature in the
veh icle.
When should th e roof rack be removed?
- Before going through an automatic car wash
(it is best to ask the car wash operator for
advice).
- When not in use, to reduce fue l consump­
tion, wind noise and to guard aga inst theft.
A WARNING
- Use of an unapproved roof rack or incor­
rect mounting of an approved roof rack

60 Seats and storage
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 vehicle
can cause a crash and personal injury .
- Only mount the roof rack on the desig­
nated locations on the roof
c> fig. 61.
-The roof rack system must be installed
exactly according to the instructions pro­
vided.
- When driving with a roof rack system,
changes to the center of gravity and wind
resistance can change the vehicle han­
dling and lead to a collision . Always
adapt your driving and your speed to the
current conditions .
@ Note
-Your vehicle warranty does not cover any
damages to the vehicle caused by using
roof racks or mounting 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
curely tightened. If necessary, retighten
the mountings and check the entire sys­
tem from time to time.
- After mounting a roof rack system, or when you transport objects on the roof
of your vehicle, the height of the vehicle is naturally increased. Be careful when
driving under low bridges or in parking
garages for example . This could cause
damage to the load and even the vehicle itself.
- Make sure the open rear lid and the sun­
roof* do not come into contact with the
roof rack.
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
evenly .
.. Always attach items to the roof rack secure-
ly before you drive off.
The maximum permissible roof weight is
220 lb (100 kg). The roof weight is the total
of the weight of the roof rack, the attach­
ments and the cargo you are carrying. You
must also not exceed the maximum load
weight for the roof rack you are using.
When using a roof rack system which has a lower load carrying capacity, you must not use
up the total maximum permissible load carry­
ing capacity specified above. Instead, you
should 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 collision and
cause serious personal injury .
- Make sure the roof rack is installed exact­
ly as specified above
c> page 59.
-Always use suitable mounting straps for
securing items to the roof rack to help
prevent items from shifting or flying for­
ward .
- Items on the roof rack must always be
securely mounted .
- The use of a roof rack can negatively af­
fect the way a vehicle handles . Cargo
that is large, heavy, bulky, long or flat
will have a greater negative influence on
the vehicle's aerodynamics, center of
gravity and overall handling. Always
drive slowly, avoid sudden braking and
maneuvers when transporting cargo on
the roof of your vehicle.
ll>-

-Never exceed the maximum permissible
load carry ing capacity of the roof of your
vehicle, the permissible axle weights and
the permissible total weight of your vehi­ cle
c;, page 280, Weights.
@ For the sake of the environment
As a result of the increased wind resist­ance created by a roof rack, your vehicle is
using fue l unnecessarily. So remove the
roof rack after using it.

- Loose objects in the passenger compart­
ment can fly forward during abrupt ma­
neuvers or accidents and injure occu­
pants.
Seats and storage 61
-Always store objects in the luggage com­
partment and use suitable straps, partic­
ularly with heavy objects.
- When you transport heavy objects, al­
ways remember that a change in the cen­
ter of gravity may result in a change in
the vehicle's handling characteristics.
- Follow all warnings
c;, page 126, Driving
Safely.
(D Tips
The tire pressure must be adjusted to the
load - see the t ire pressure sticker located
on the driver's side 8-pillar.

Stowing luggage.
In a collision, the laws of physics mean that
even smaller items that a re loose in the vehi­
cl e w ill turn in to heavy m iss iles tha t ca n cause
serious injury. Items in the veh icle p ick up ki­
ne tic energy which varies with the vehicle and
the weight of the item . Vehicle speed is the
most sign ificant factor.
F o r ex ample, in a fro nta l collision at a speed
of 30 mph (48 km/h), the forces acting on a
10 -lb (5 kg) object are abo ut
20 times the
norma l weight of the item. This means that
the weight of the item wou ld sudden ly be the
equivalent of about 200 lbs (90 kg) . One can
easily imagi ne the injuries that an item of that
weight flying freely through the passenger ..,.

compartment can cause in a collision at a
speed considered relatively low .
A WARNING
Weak, damaged or improper straps used
to secure items to tie-downs can fail dur­
ing hard braking or in a collision and cause
serious personal injury.
- Always use suitable retaining straps and
properly secure items to the tie-downs in
the luggage compartment to help pre­
vent items from shifting or flying for­
ward.
- Never attach a child seat tether strap to
a tie-down.
- For strength-related reasons, the mount­
ing hooks can only be used to secure ob­
jects we ighing up to 10 lb. (5 kg) . Heavi­
er objects will not be adequa tely secured
- there is a risk of injury.

Climate controls
Description
A pplies to vehicles: with three-zone cl imate cont ro l or
four-zone a uto mat ic climate contro l
The climate control system warms, cools and
adds humidity to the air in the vehicle interior. It is the most effective when the windows and
sunroof* are closed .
If the temperature inside
the parked veh icle becomes very warm, open ­
ing the w indow br iefly will speed up the cool­
ing process.
In all heating mode functions except
defrost,
the blower on ly switches to a highe r speed
once the engine coolant has reached a certain
temperature.
Condensat ion from the cooling system can
d rip and form a puddle of wate r under the ve­
h icle. This is normal and does not mean there
is a leak .
Pollutant filt er
The pollutant filter removes pollutants such
as dust and po llen from the air.
The air pollutants filter must be changed at
the intervals spec ified in your Warranty
&
Maintenance booklet, so that the air condi­
tioner can properly work .
If you drive your vehicle in an area with high
a ir pollution, the filter may need to be
changed more freq uently than specified in
your Aud i Warranty & Ma intenance booklet. If
i n doubt, as k your author ized Audi Se rvice Ad­
visor for adv ice.
K ey coded setting s
Three-zone climate control: The blower set­
ting and air distribution are stored automati­
cally and assigned to the remote control key
that is in use.
Four-zone automatic climate control: The cli­
mate control settings are automatica lly stor­
ed and assigned to the remote control key
that is in use.
A WARNING
Reduced visibility is dangerous and can
cause accidents.
-
- For safe driving it is very important that
all windows be free of ice, snow and con­
densat ion .
- Comp lete ly fami liarize yourse lf with the
proper use and funct ion of the heat ing
and ventilation system and especially
how to defog and defrost the w indows.
- Never use the windshield wiper/washer system in freez ing weather unt il you
have wa rmed the windshie ld first, using
the heating and ventilation system. The
washer sol ution may freeze on the w ind­
shie ld and red uce visib ility.
(D Note
- If you suspect that the air conditioner
has been damaged, switch the system
off to avoid further d amage and have i t
inspected by a q uali fied dealership .
- Repairs to the Audi air conditioner re­
quire speci al technical know ledge and
special tools. Contact an authorized Audi
dea ler fo r ass istance.
@ For the sake of the environment
By reducing the amount of f uel you use,
you also red uce the amount of pollutants
emitted into the air.
(D Tips
- Keep the air intake s lo ts (in front o f the
windshield) free from ice, snow and de ­
bris in order to maintain the proper func­
tion of the climate control system.
- The energy management system may
switch the seat heating* or rear window
defroster off temporar ily. These systems
are available again as soon as the energy
balance has been restored .
-Air escapes through vents under the rear
