2014 AUDI A6 Owners Manual

-Never place or attach accessories or o th ­
er objects (such as cup hol ders, tele­
phone brackets, large, heavy or bulky ob­
jects) on the doors, over or near the area
marked ''AIRBAG" on the steering wheel,
instrument panel, seat backrests or be­
tween those a reas and yourself. These
objects co uld cause injury in a crash, es­
pecially when the airbags inflate .
- Never recline the front passe nger's seat
to transport objec ts. Items can also
move into the area o f the side airbag or
the front airbag during braking or in a
sudden maneuver . Objects near the air­
bags can become project iles and cause
injury, part icularly when the seat is re­
cl ined .
- Never place or transport ob jects on the
front passenger seat. Objects on the
front passenger seat could cause the ca­ pacitive senso r in the seat to s ignal to
airbag system that the seat is occupied
by a person when it in fa ct is not, o r that
the person on the se at is he avier than he
or she actually is. The change in electric
capacitance beca use of such objects can
cause the passenger front airbag to be
turned on when it sho uld be
off, or can
cause the airbag to work in a way that is
different from the way it wou ld have
worked w ithout objects on the seat.
- Always make sure that there is nothing
on the front passenger seat that will
cause the capacitive passenge r detection
system in the s eat to s ignal to the A irbag
System that the seat is oc cupied by a
pers on when it is not, or to sign al th at it
is occupied by someone who is heavier
than the pe rson actually s itting on the
seat . The presence of an object co uld
cause the passenger front a irbag to be
turned on when it sho uld be
off, or co uld
cause the airbag to work in a way that is
different from the way it wou ld have
worked w ithout the object on the seat. A

A WARNING
The fine dust created when airbags deploy
can cause breathing prob lems fo r people
with a history of as thma or other breath­
ing cond itions.
- To reduce the risk of breath ing problems,
those wi th asthma o r other respiratory
conditions s hou ld get fresh air r ight
away by get ting o ut o f the veh icle or
open ing win dows or do ors.
- If you are in a collision in which airbags
deploy, was h your ha nds and fa ce with
mild soap and wate r be fore eating.
- Be ca reful not to get the dust in to your
eyes, o r into any c uts or sc ratches.
- If the resid ue should get into your eyes,
f lus h t hem w ith wa te r.

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
-If the status of the Advanced A irbag Sys­
tem has changed wh ile the vehicle is
moving, the
PASSENGER AIR BAG OFF
light blinks for about 5 seconds to catch
the drive r's attent ion.
If this happens, al­
ways s top as soon as it is safe to do so
and check the steps described above.
- If the
PASSENGER AIR BAG OFF light
does not go off whe n an adu lt who is no t
very small is sitting on the front passen ­
ger seat after taking the steps described
above, make sure the adult is properly
seated and restrained at one of the rear
seating pos itions. Have the a irbag sys­
tem inspected by your authorized Audi
dealer before transpo rting anyone on the
front passenger seat.
A WARNING , --
An airbag system that is not funct io ning
prope rly cannot provide supplemental p ro­
tect ion in a fron tal crash.
- If the airbag indicator light ~ page 19
comes when the vehicle is be ing used,
h ave t he system inspected immedi ate ly
by yo ur authorized Aud i dea ler .
It is pos­
sible that the airbag will inflate when it is not supposed to, or will not
inflate
when it should.
A WARNING
-If the front airbag inflates, a child without
a child restraint, or in a rearward-facing
chi ld safety seat, or in a forward -facing
chi ld restraint that has not been proper ly
i nstalled w ill be seriously injured and can
b e killed.
- Even though you r vehicle is equipped
with an Adva nced A irbag System, make
certain that all children, espe cial ly 12
ye ars and you nger, always ride on the
back seat properly rest rained for their
age and size .
- Always inst all forward o r rear-fa cing
child seats on the rear sea t - even with
an Advanced A irbag System.
- If you must ins tall a rearwa rd -facing
child seat on the front passenger seat because of exceptional circumstances
and the
PASSENGER AIR BAG OFF light
does not appear and stay on, immediate ­
ly install the rear-facing child seat in a
rea r seat ing pos ition and have the airbag
sys tem inspected by you r Audi dealer .
- If, in exceptiona l circumstances, you
m ust install a forward-fac ing c hild re­
straint on the front passenger seat, al­
ways move the seat into its rearmos t po­
sition in the se at's fore and aft adjust­
men t range, as far away from the a irbag
as poss ible . The backrest mus t be ad just­
ed to an upright pos ition . Make su re that

does not go out when an adult is sitting
on the front passe nger seat after taking
the steps described above, make su re the
adu lt is prope rly seated a nd restra ined at
one o f the rea r seat ing pos itions.
~

-Have the airbag system inspected by
your Audi dealer before transporting
anyone on the front passenger seat.
(D Tips
If the capacitive passenger detection sys­
tem determines that the front passenger seat is empty, the frontal airbag on the
passenger side will be turned off, and the
PASSENGER AIR BAG OFF light will stay
on .
Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places on your Audi. Installing,
removing, servicing or repairing a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a collision.
There are some important things you have to know to make sure that the effectiveness of
the system will not be impaired and that dis­
carded components do not cause injury or pol­
lute the environment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag from deploying when needed or deploying
an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way .
- Never attach any objects such as cup
holders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de­
ploy and protect properly.
Airbag system 163
- Never repair, adjust, or change any parts
of the airbag system.
- All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including the installation of audio
equipment, cellular telephones and CB radios, etc .) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work­
shop.
- Never modify the front bumper or parts
of the vehicle body.
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can deploy only once .
After an airbag has been deployed, it
must be replaced with new replacement
parts designed and approved especially
for your Audi model version. Replace­ ment of complete airbag systems or air­
bag components must be performed by
qualified workshops only. Make sure that
any airbag service action is entered in
your Audi Warranty
& Maintenance book­
let under
AIRBAG REPLACEMENT RE­
CORD .
-For safety reasons in severe accidents,
the alternator and starter are separated
from the vehicle battery with a pyrotech­
nic circuit interrupter.
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a

- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.
@ For the sake of the environment
Undeployed airbag modu les and preten­
sioners might be classified as Perchlorate Material - special handling may apply, see
www.dtsc.ca.gov/haza rdouswaste/per­
chlorate. When the vehicle or parts of the
restraint system including airbag modules
and safety belts w it h pretens ioners are
s crapped, a ll applicable laws and regula­
tions mus t be observed. Your au thori zed
Audi dea le r is familiar with these requi re­
ments and we recommend that you have
your dea ler perfo rm this serv ice for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced A irbag Sys­
tem pe rforms in a crash. For example, us ing
tire-r im combinations not app roved by Aud i,
lowering the vehicle, ch anging the stiffness o f
the suspension, including the springs, suspen ­
sion struts, shock absorbers etc. can change
the forces that are measured by the a irbag
sensors and sent to the electronic control
un it. Some suspension changes can, for exam­
p le, increase the force levels measured by the
sensors a nd make the airbag system deploy in
crashes in w hich it would not dep loy if the
changes had not been made . Other kinds of
ch an ges may reduce the force levels meas­
u red by the sensors and prevent the airbag
from deploying when it sho uld .
The senso rs in the safety belt buckle fo r th e
d river a nd front passe nger sea t tell the elec ­
tronic control module if the safety belt is
l atched or not .
If the safety belt is being used,
the front airbag will dep loy at a slightly high­
er rate of vehicle deceleration than if the safe­
ty belt is not being used. Therefore, in a par- t
icu lar collision, it is possible that an airbag
will not dep loy at a seat ing position where the
safety belt is be ing used b ut w ill inflate at the
pos ition where the safety belt is not be ing
used. It is important that nothing interfere
with t he safety be lt buckles so that the sen ­
sors can send the correct info rmation about
safety belt use to the electronic control un it .
_&. WARNING
Changi ng the vehicle's suspension includ ­
i ng use of unapp roved tire-rim combina­
tions can change Advanced Airbag per­
formance and increase the risk of serious pe rsonal injury in a crash .
- Never install suspension components that do not have the same pe rformance
characteristics as the components o rigi­
na lly installed on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
Knee airbags
Description of knee airbags
App lies to vehicles : wi th knee airbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants .
Fig . 1 61 Dr iver 's knee a irbag
T he dr iver knee airbag is in the ins trument
pane l underneath the steering wheel
~ fig. 161, the airbag for the passenger is at
about the same height in the instrument pan-
el underneat h the glove compartment. .,.

The knee airbag offers additional protect ion
to the driver's and passenger's knees and up­
per and lower thigh areas and supp lements
the protect ion provided by the safety belts.
I f the front airbags deploy , the knee airbags
also deploy in fronta l collisions when the de ­
p loyment threshold stored in the control unit
is met c>
page 157, More important things to
know about front airbags.
In addition to their normal safety function,
safety be lts he lp keep the driver or front pas ­
senger in posit ion in a frontal coll is ion so that
the airbags can prov ide supplemental protec­
tion .
The airbag system is not a subst itute for yo ur
safety be lt. Rather, it is part of the overall oc­
cupant restraint system in your veh icle. Al­
ways remember that the airbag system can
only help to protect you if you are wea ring
your safety belt and wear ing it prope rly . Th is
i s why you shou ld always wear you r safety
be lt, not just because the law requires yo u to
do soc>
page 138, General notes.
The safety belt buck le for the dr iver and front
seat passenge r have switc hes that tell the a ir­
bag con trol mod ule if the safety belt is be ing
used or not . If the safety belt is being used,
the knee airbag will deploy at a slightly higher rate of deceleration than if the belt is not be ­
ing used. Therefore, in a particu lar 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 whe re the
safety belt is not be ing used.
Remember too, airbags will deploy only once
and only in certain kinds of accidents -your
safety belts are always there to offer protec ­
tion in those acc idents in which a irbags a re
not supposed to deploy or when they have a l­
r eady deployed, fo r example whe n your veh i­
cle strikes or is s truck by another afte r the
fi rst coll is ion .
This is just one of the reasons why an a irbag is
n ot a substi tute fo r the safety belt. The airbag
sys tem works most effective ly when used with
A irbag system 165
the safety belts. Therefore, always wear yo ur
safety belts correct ly .
I t i s important to remembe r that w hile the
s u pplementa l knee airbag system is designed
to reduce the likelihood of ser ious injuries,
other injuries, for example, swelling, bruising
and minor abrasions and friction b urns can a l­
so occur when an airbag inflates.
The knee airbag system basically consists
of:
- The e lectronic control module
- Two inflatable ai rbags (airbag and gas gen -
erator), one for the driver and one for the
front passenger
- The ai rbag indicator lig ht in the instrument
pane l
The knee airbag system will not deploy:
-when the ignit io n is switched off
- in frontal collisions when the deceleration
meas ured by t he con trol un it is too low
- in side co llisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunction (warn-
ing/ind icator light is on)
i=> page 19.
A WARNING
-Safety belts and the airbag system can
only provide protection when occupa nts
are in the proper seating position
i=>page 157.
- If the airbag ind icator light i=> page 19
comes when the veh icle is being used,
have the system inspe cted immediately
by your au thori zed A udi dealer.
It is pos­
sib le tha t the airbag will infla te when i t
is not supposed to, or will not infla te
when it should .

166 Airbag system
How knee airbags work
Applies to vehicles: with knee airbags
The risk of injury to the leg area can be re­
duced by fully inflated knee airbags.
Fig. 162 Inflated airbags protecting in a frontal colli·
s io n
The knee airbag system has been designed so
that the a irbags for the driver and front pas­
senger deploy in certain but not all frontal
collisions.
If the front airbags deploy, the knee airbags
a lso deploy in frontal collisions when the de­
ployment threshold stored in the control unit
is met .
When the system deploys, the airbags fill
with a propellant gas, and inflate between the
lower part of the instrument panel and the
driver and the lower part of the instrument
panel and the front passenger
Q page 157,
fig . 159.
Although they are not a soft pillow, they can
"cush ion" the impact and in this way they can
help to reduce the risk of injury to the lower
extremities.
All of this takes place in the blink of an eye, so
fast that many people don't even realize that
the airbags have deployed . The airbags also
inflate with a great deal of force and it is im­
portant for occupant safety that nothing
should be in their way when they deploy.
Fully inflated airbags in combination with
properly worn safety belts slow down and lim­
it the occupant's forward movement and help
to reduce the risk of injury. Important safety instructions on the
knee airbag system
Applies
to vehicles: with knee airbags
Airbags are only supplemental restraints. Al­
ways wear safety belts correctly and ride in a
proper seating position .
There is a lot that you and your passengers
must know and do to help the safety belts and
airbags to provide supplemental protection.
A WARNING
-An inflating knee airbag can cause serious injury. Wearing safety belts incorrectly and
improper seating positions increase the
risk of serious personal injury and death
whenever a vehicle is being used.
- The knee airbag system cannot protect
you properly if you are seated too close
to any of the airbag locations. When ad­
justing their seat positions, it is impor­
tant that both the driver and the front passenger keep their upper bodies and
knees at the following minimum safe
distances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instru­
ment panel.
- at least 4 inches (10 cm) between the knees and the lower part of the instru­
ment panel.
- The risk of personal injury increases if
you lean forward or to the side, or if the
seat is improperly positioned and you are
not wearing your safety belt . The risk in­
creases even more should the airbag de­
ploy .
- Always make sure that the knee airbag
can inflate without interference. Objects
between you and the airbag can increase
the risk of injury in an accident by inter­
fering with the way the airbag deploys or
by being pushed into you as the airbag
deploys.
- Never let anybody, especially children
or animals ride in the footwell in front
