They could slide during sudden braking ma­
neuvers and cause injuries.
- Sharp edges on objects that are loaded
must be covered for protection.
- When releasing the rear seat backrest,
make sure there are no people or anima ls
with in its range of motion. The backrest will
fold forward automatically after it is re­ leased.

Roof rack
Applies to: vehicles without roof rail
Fig. 79 Mounting po ints for the roof rack
Applies to: vehicles with roof rail
Fig. 80 Moun ting points fo r the roof rack
If luggage or cargo is to be carried on the roof,
you must observe the following:
- Only a specially designed roof rack may be used
on your vehicle. These roof racks are the basis
for a complete roof rack system. Additional at­
tachments/carr ier systems are necessary to
transport luggage and sports equipment. We
..,.

u. 00 .-< N l'­ N .-< 0 N > 00
recommend roof racks and attachments from
the Audi Genuine Accessories program.
- When installing the roof rack, make sure that it
is mounted on ly at the designated points on
the roof ¢
fig. 79 or ¢ fig. 80.
-Note the permitted axle load, permitted tota l
weight, and permitted roof load of your vehicle
¢
page 382 . The roof load is the tota l of the
weight of the roof rack, the attachments and
the cargo you are carrying. However, you must also note the permitted load of the carr ier sys­
tem being used .
A WARNING
-Follow the installat io n instructions provided
with the roof rack system. If you do not se­
cur e the roof ra ck sys tem and objec ts on the
roof correctly, they co uld come loose from
the vehi cle and cause an accident.
- T he ris k of an a cc ident i ncreases when using
a roof rack system, because it changes the
driving characteristics by shifting the center
of gravity and/or the increasing the s urface
area exposed to wind. You may need to
adapt your driv ing style and speed to the
current conditions.
@ Note
- If you use other roof luggage rac k systems
or do not insta ll the racks as intended, any
damage to the ve hicle is not cove red by the
warranty. Carefully follow the assembly and i nsta llation instruct ions included with the
r oof rack car rier system .
- Make sure t hat the luggage compartment
l id and the pa norama glass
roof* do not
come into contact with objects on the roof
whe n they are ope n.
@) For the sake of the environment
Your veh icle w ill req uir e more fuel due to the
increased wi nd resistance. So remove th e roof
rac k after using it.
Seat s and sto rag e

Driving
When not being used, a roof rack should be re­
moved to decrease the wind resistance of the ve­
hicle. This will save you approximately 12% fuel
at speeds from 62
-75 mph (100 -120 km/h).
Save energy
The engine drives the generator, which generates
electricity; the fuel consumption also increases
with the demand for electricity. Therefore, switch
electrical equipment
off when you no longer
need it. Examples of equipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating* .
(D Note
-Do not leave engine idling unattended after
starting. If warning lights should come on
to indicate improper operation, they would
go unheeded. Extended idling also produces
heat, which could result in overheating or
other damage to the vehicle or other prop­ erty.
- Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book­
let . Lack of proper maintenance as well as
improper use of the vehicle will impair the
function of the emission control system and
could lead to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such as
heat shields, switches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other
important vehicle components.
@ Tips
The consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehicle
load and speed, road and weather conditions,
trip length, etc.

Steering
Adjusting the steering wheel position
The steering wheel position is fully adjustable up
and down and forward and back.
Fig . 83 Steering column : steering column adjustment lever
.. Tilt the lever -c> fig. 83 downward¢ ,&..
.. Bring the steering wheel into the desired posi­
tion.
.. Push the lever against the steering column un­
til it is secure.
A WARNING
Incorrect use of the steering wheel adjust­
ment and an incorrect seating position can
cause serious injuries.
- Only adjust the steering column when the veh icle is stationary so that you do not lose
control of the vehicle.
-
-Adjust the driver's seat or steer ing wheel so
that there is at least 10 inches
(25 cm) dis­
tance between your chest and the steering
wheelr::!>page250, fig. 217. If you do not
maintain this distance, the airbag system
will not be able to provide its full protec­ tion.
c:> page 250, fig. 217.
- If your physical characteristics prevent you
from sitting at least 10 inches
(25 cm) or
more away from the steering wheel, see if
an authorized Audi dealer or authorized
Audi Service Facility can provide adapters that will help.
- If your face is level with the steering wheel,
the airbag does not provide as much protec­
tion during a collision. Always make sure
that the steering wheel is level with your
chest.

Airbag syste m
-If you are unrestrained, leaning forward, sit­
t ing s ideways or out of pos ition in any way,
your risk of injury is much h igher.
- You will also receive serious injuries and
could even be killed if you are up aga inst the
airbag or too close to it when it inflates -
even with an Advanced
Airbag ¢ page 269.
A WARNING
A child in a rearward -facing child seat instal­
led on the front passenger seat will be ser i­
ously inju red and can be killed if the front air­
bag inflates - even with an Advanced Airbag
System.
- Although the Advanced A irbag System in
yo ur vehicle is designed to tu rn off the front
airbag when a rearward-facing child re­
straint has been insta lled on the front pas ­
senger seat, nobody can absolutely g uaran­
tee that deployment is impossible in all con­ ceivable s ituations that may happen during
the useful life of your vehicle.
- The inflating airbag will hit the child seat or infant carrier w ith great force and will
smash the ch ild seat and child against the
backrest, center armrest, door, or roof .
- Always install rearward-facing ch ild re­
straints on the rear seat .
- If you must install a rearward fac ing ch ild
seat on the front passenger seat because of
exceptional c ircumstances and the
PA SSEN­
GER AIR BAG OFF
light does not come on
and stay on, immediately insta ll the rear­
facing child seat in a rea r seating position
and have the airb ag system inspected by
yo ur Audi dealer .
A WARNING
If, in exceptional circumstances, you must in ­
stall a forward-facing chi ld restraint on the
front passenger's seat :
- Always make sure the forward -facing seat
has been designed and certified by its man­
ufacturer for use on a front seat with a pas­
senger front and side a irbag.
276
-
- Never put the fo rward-facing child restraint
up against or very near the instrument pan­
el.
- Always move the front passenger seat to
the highest posit ion in the up and down ad­
justment range and move it back to the rearmost posit ion in the seat's fore and aft
ad justment range, as far away from the a ir­
bag as poss ible, before installing the for­
ward-f acing chi ld restrain t.
- Always make sure that the safety be lt upper
anchorage is behind the ch ild rest raint and
not next to o r in fron t of the child rest raint
so th at the s afety be lt will be p roperly posi­
tioned.
- Always make sure th at there is noth ing on
the front passenger seat that will cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
the seat is occup ied by a person when it is
not, or to signal that it is occupied by some­
one who is heavier than the person actually
sitt ing on the seat . The presence of addi­
tional objects could cause the passenger
front airbag to be turned on when it should
be off, or could cause the airbag to work in a
way th at is differen t from the w ay it wou ld
have worked without the objec t on the seat .
- Ma ke sure th at the
PASSENGER AIR BAG
OFF
li ght comes on and stays on all the time
whenever the ignition is switched on .
Advanced Airbag System components
The front passenger seat in your vehicle has a lot
of very important parts of the Advanced Airbag
System in it. These pa rts include the capacitive
passenger detection system, wir ing, brackets,
and more . T he control unit monitors the system
o n the front passenger seat when the ignit ion is
switched on a nd turns the airbag indicato r light
o n when a malfunction in the one of the system
components is
detected ¢ page 281. Because
t h e fron t passenger sea t contains impo rtan t
parts of the Advanced Ai rbag System , you must
take care to prevent it from being damaged .
Damage to the seat may prevent the Advanced

Airbag syste m
A WARNING
A child in a rearward-facing child seat instal­
led o n the front passenger seat will be ser i­
ously injured and can be k ille d if the front air­
bag in flate s - even with an Advanced Airbag
System.
- The inflating a irbag w ill hit the child seat or
infant carrier w ith great force and will
smash the ch ild seat and child against the
backrest, cente r arm rest, door or roof.
- Always install rear-facing child seats on the
rea r seat.
- If you must install a rearward fac ing ch ild
seat on the front passenger seat because of
exceptional c ircumstances and the
PASSEN­
GER AIR BAG OFF
light does not come on
and stay on, immediately insta ll the rear­
facing child seat in a rear seating position and have the airbag system inspected by
your Audi dealer.
A WARNING
-
-
Objects between you and the a irbag w ill in­
crease the risk of in jury in a crash by interfer­
ing w ith the way the airbag unfolds or by be­
ing pushed into you as the a irbag inflates.
- Never hold th ings in your hands or on your
lap when the vehicle is in use .
- Never transport items on or in the area of
the fron t passenger seat . Objects could
move into the area of the front airbags du r­
ing bra king or other sudden maneuve rs and
become dangerous projec tiles that c an
ca use serious pe rsonal injury if the a irbags
inflate.
- Never pl ace or attach accessor ies or o ther
objects (such as cup ho lders, te lephone
brackets, large, heavy or bulky objects) on
the doors, over or nea r the area marked
"AIRBAG" on the steering wheel, instru­
ment pane l, seat backrests or between
those areas and yourself. These objects could cause injury in a crash, especially
when the airbags infla te.
- Never recline the front passenger's seat to
transport objects . Items can also move into
the a rea of the side airbag o r the front a ir-
280
bag du ring brak ing o r in a sudden maneu­
ver. Objects near the airbags can become pro jecti les and cause injury, part icularly
when the seat is reclined .
- Never p lace or transport objects on the
front passenger seat. Objects on the front passenger seat could cause the capacitive
sensor in the seat to signal to ai rbag system
that the seat is occ upied by a person when it
in fact is no t, or that the pe rson on the seat
is he avie r th an he or she act ually is. The
change in electric capacitan ce beca use of
such objects can cause the passenge r front
airbag to be turne d on when it should be
off, or can cause the airbag to work in a way
that is different from the way it would have
wo rked without objects on the seat.
- Always make sure that there is noth ing on
the front passenger seat that will cause the
capacitive passenger detection system in
the sea t to signal to the Airbag System that
the seat is occup ied by a person when it is
not, or to signal that it is occupied by some­
one who is heavier th an the person actu ally
si tting on the sea t. The presence of an o b­
ject could ca use the passenger front air bag
to be turned on when it should be off, or
could cause the airbag to work in a way that is diffe rent from the way it would have
worked without the object on the seat.
A WARNING
The fine dust created when airbags deploy can
cause breathing prob lems for people with a
h istory of asthma or othe r breath ing cond i­
tions .
- To reduce the r isk of breathing p roblems ,
those wi th asthma o r other respiratory con­
ditions sho uld get fresh a ir rig ht away by
getting out of the vehi cle or opening win­
dows or doors.
- If you are in a co llision in which airbags de­
ploy, w ash yo ur hands and f ace with m ild
soap and water be fore eating.
- Be ca refu l not to get the dust into your eyes,
or into any cuts or scratches.
- If the residue sho uld get into your eyes,
flush them w ith wate r.

Airbag system
-Damage to the original seat covers or to
the seam in the area of the side airbag module must always be repaired immedi­
ately by an authorized Audi dealer .
- Objects between you and the airbag can in­
crease the risk of injury in an accident by in­
terfering with the way the airbag unfolds or by being pushed into you as the a irbag in­
flates.
- Never place or attach accessories or other
objects (such as cup holders, telephone
brackets, or even large, bulky objects) on
the doors, over or near the area marked
"AIRBAG" on the seat backrests .
- Such objects and accessories can become
dangerous projectiles and cause injury
when the supplemental s ide airbag de­
ploys.
- Never carry any objects or pets in the de­
ployment space between them and the
airbags or allow chi ldren or other passen­
gers to travel in this posit ion.
- Always use the built-in coat hooks only for
lightweight clothing . Never leave any heavy
or sharp-edged objects in the pockets that
may interfere with side airbag deployment
and can cause personal injury in an accident .
- Always prevent the side airbags from being
damaged by heavy objects knocking against
or hitting the sides of the seatbacks.
- T he airbag system can only be triggered
once .
If the airbag has been triggered, the
system must be replaced by an authorized
Audi dealership.
- Damage (cracks, deep scratches etc.) to the
original seat covers or to the seam in the
area of the side airbag modu le must always
be repaired immediately by an authorized
Audi dealer.
-If children are seated improper ly, their risk
of injury increases in the case of an acc ident
¢ page 2 94, Child safety.
-Never attempt to modify any components of
the a irbag system in any way.
-In a side collision, side airbags w ill not func­
t ion properly if sensors cannot correctly
measure increasing air pressure inside the
290
doors when air escapes through larger, un­
closed openings in the door panel.
- Never drive with inte rior door trim panels
r emoved.
- Never dr ive when parts have been re­
moved from the inside door panel and the
openings they leave have not been proper­
l y closed.
- Never drive when loudspeakers in the
doors have been removed unless the
speaker holes have been properly closed.
- Always make certain that openings are
cove red or filled if additional speakers or
other equipment is installed in the inside
door panels .
- Always have work on the doors done by an
authorized Aud i dealer or qualified work­
shop .
