A WARNING
- To reduce the risk of an accident, on ly adjust
the front seats when the vehicle is station­
ary.
- The power adjustment for the front seats al­
so works w ith the ignition switched off or
with the ignition key removed . T o reduce
the risk of injury, chi ld ren should never be
left unattended in the vehicle for this rea­
son.
- Exercise caution when adjusting the seat
height. Uns uperv ised or careless seat ad­
justment can p inch f ingers or hands, wh ich
increases the risk of injury.
- T he front seat backres ts m ust not be re­
clined too far back when driving, because
this impairs the effectiveness of the safety
belts and airbag system, which increases
the risk of injury.

Autom atic safety belt retractors
Every safety belt is equipped with an automatic
belt retractor on the shoulder belt . This feature
locks the belt when the belt is pulled out fast,
du ring hard braking and in an accident . The be lt
may a lso lock when you drive up or down a steep
h ill or th rough a sharp curve. Dur ing no rma l dr iv­
i n g the bel t lets you move freely.
Safety belt pretensioners
Safety belts w ith pretensioners help to tighten
the safety belt and remove slack when the pre­ tensioners a re
activated ¢ page 267. The func­
tion of the pretens ioner is moni to red by a w arn­

i mportant information about this feature
¢ page 305 .
A WARNING
Improperly positioned safety belts can cause
serious inj ury in an
accident ¢ page 265,
Safety belt position .
- Safety belts offer optimum protection only
when the seatback is up right and belts are
properly posit ioned on the body .
- Always make sure that the rear seat back ­
rest to which the center rear safety belt* is
at tached is securely latched whenever the
rear cen ter safety belt is being used.
If the
b ackrest is not sec urely latche d, the passen­
ger will move forward with the bac krest du r­
ing sudden b raking, in a sudden maneuver
and especia lly in a crash.
-Never attach the safety belt to the buckle
for another seat. Attaching the belt to the
wrong buckle will reduce safety be lt e ffec­
tiveness and can cause serio us personal in­
jury.
-A passenge r who is not properly restrained
can be seriously injured by the safety belt it­
self when it moves from the stronger parts
of the body into cri tical areas like the abdo­
men .
- Always lock the convertible locking retractor when yo u are securing a c hild seat in the ve­

Airbag System for the front passenger seat from
doing its job in a crash.
The front Ad vanced Airbag System con sists
o f th e follo wing :
-Cras h sensors in the front of the vehicle that
measure vehicle acceleration/deceleration to
provide information to the Advanced Airbag
System a bout the severity of the crash.
- An electronic control unit, with integrated
crash sensors for front and side impacts. The
contro l unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors . The control unit also "de­
c ides" whether the safety belt pretens ioners
shou ld be activated .
-An Advanced Airbag with gas generator for the
dr iver inside the steering wheel hub.
-An Advanced Airbag with gas generator ins ide
the instrument panel for the front passenger.
-A capac itive passenger detect io n system under­
neath the front passenger seat cover. This sys­
tem measures the elect rical capac ita nce of the
person in the seat. The info rmat ion registe red
is sent cont inuous ly to the electro nic cont rol
u nit to regula te deployment of t he front Ad ­
vanced Airbag on the passenge r side.
-An a irbag monito ring system and indica tor
li gh t in the ins trument
cluste r¢ page 281 .
-A se nso r in each front seat reg isters the dis ­
tance between the respec tive sea t and the
steering wheel or instrument pane l. The infor ­
mation registered is sent continuous ly to the
electronic control unit to regulate deployment
of the front Adv a need A irbags.
-T he PASSENGER AIR BAG OFF light comes on
and stays on in the center of the instrument
panel
¢ page 318 and tells you when the front
Advanced Airbag on the passenger side has been turned off .
-A sensor in the safety belt latch for the driver
and for the front seat passenger that senses
whether that safety belt is latched or not and
transm its this info rmat ion to the elect ronic
contro l unit.

-For adjustable head restraints: adjust or re­
move the rear seat head restraint if it is dif­
ficult to install the child seat with the head restraint in place
c> page 61 . Install the
head restraint again immediately once the
child seat is removed. Driving without head
restraints or with head restraints that are
not properly adjusted increases the risk of
serious or fatal neck injury dramatically.
- Always read and heed all WARNINGS when­
ever using a child restrained in a vehicle is
being used
c> page 260, Safety belts,
c> page 269, Airbag system and
c> page 294, Important information.
A WARNING
If exceptional circumstances require the use
of a forward-facing child restraint on the
front passenger's seat, the child's safety and
well-being require that the following special
precautions be taken:
- Make sure the forward-facing seat has been
designed and certified by its manufacturer
for use on a front seat with a passenger
front and side airbag .
- Always follow the manufacturer's instruc­ tions provided with the child safety seat or
infant carrier.
- Always move the front passenger seat to
the highest position in the up and down ad­
justment range and move it back to the
rearmost position in the seat's fore and aft
adjustment range, as far away from the air­
bag as possible, before installing the for­
ward-facing child restraint.
- Always make sure that the safety belt upper
anchorage is behind the child restraint and
not next to or in front of the child restraint
so that the safety belt will be properly posi­
tioned.
- Always make sure that nothing prevents the
front passenger's seat from being moved to
the rearmost position in its fore and aft ad­
justment range.
- Always make sure the backrest is in an up­
right position.
Child safety
-Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heater
for child seats) on the front passenger seat
if the device is connected to the 12-volt
socket or the cigarette lighter socket.
- If a seat heater has been retrofitted or oth­ erwise added to the front passenger seat, never install any child restraint system on
this seat.
- Make sure that there are no wet objects
(such as a wet towel) and no water or other
liquids on the front passenger seat cushion.
- Never place objects on the seat (such as a
laptop, CD player, electronic games device,
power inverter or seat heater for child
seats). These may influence the electrical
capacitance measured by the capacitive pas­
senger detection system and can also fly
around in an accident and cause serious per­
sonal injury.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the time
whenever the ignition is switched on.
- If the
PASSENGER AIR BAG OFF light does
not come on and stay on, immediately in­
stall the forward-facing child seat at a seat­ ing position on the rear seat and have the
airbag system inspected by your authorized
Audi dealer .
- Take the child restraint off the front passen­
ger seat and install it properly at one of the
rear seat positions if the
PASSENGER AIR
BAG OFF
light does not stay on whenever
the ignition is switched on.
