_& 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.
- 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
286
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 detect ion system and can also fly
around in an accident and cause serious per­
sonal injury.
- Make sure that the

- If the

does not come on and stay on, immediately
install the forward-facing child seat at a
seating position on the rear seat and have
the airbag system inspected by your author­
ized 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

Booster seats and safety belts
Properly used booster seats can help protect
children weighing between about 40 lbs. and 80
lbs. (18 kg and 36 kg) who are less than 4
ft. 9
in. (57 inches/1.45 meters) tall.
Fig. 233 Rear seat: child p roper ly restrained in a booster
seat
The vehicle's safety belts alone will not fit most
children until they are at least 4
ft. 9 in. (57 in­
ches/1.45 meters) tall and weigh about 80 lbs.
(36 kg). Booster seats raise these ch ildren up so
that the safety belt will pass properly over the
stronger parts of their bodies and the safety belt
can help protect them in a crash.
.,. Do not use the convertible locking retractor
when using the vehicle's safety belt to restrain
a chi ld on a booster seat .
.. The shoulder belt must lie as close to the cen­
ter of the child's collar bone as possible and must lie flat and snug on the upper body. It
must never lie across the throat or neck. The
lap belt must lie across the pelvis and never
across the stomach or abdomen. Make sure the
belt lies flat and snug. Pull on the belt to tight­
en if necessary .
.,. If you must transport an older chi ld in a boos­
ter seat on the front passenger seat, you can
use the safety belt height adjustment to help
adjust the shoulder portion properly .
.. Secure unused safety belts on the rear seat
r:=>page 283.
Children up to at least 8 years old (over 40 lbs. or
18 kg) are best protected in child safety seats de­
signed for their age and we ight. Experts say that
the skeletal structure, part icularly the pelvis, of
these children is not fully developed, and they
Child safety
must not use the vehicle safety belts without a
suitable child restraint.
It is usually best to put these children in appro­
priate booster seats. Be sure the booster seat
meets all applicab le safety standards .
Booster seats raise the seating position of the
child and reposition both the lap and shoulder
parts of the safety belt so that they pass across
the child's body in the right places. The routing of
the be lt over the chi ld's body is very important
for the ch ild's protection, whether or not a boos­
ter seat is used. Children age 12 and under must
always ride in the rear seat.
Children who are at least 4
ft. 9 in. (57 inches/
1.45 meters) tall can generally use the vehicle's
three point lap and shoulder belts . Never use the
lap belt portion of the vehicle's safety belt alone
to restrain any ch ild, regard less of how big the
ch ild is. Always remember that child ren do not
have the pronounced pelvic structure required for
the proper function of lap be lt portion of the ve­
hicle's three point lap and shoulder belts. The
child's safety absolutely requires that a lap belt
portion of the safety belt be fastened snug ly and
as low as possible around the pe lvis. Never let
the lap belt portion of the safety belt pass over
the child's stomach or abdomen .
In a crash, airbags must inflate within a blink of
an eye and with considerab le force. In order to do
its job, the airbag needs room to inflate so that it
will be there to protect the occupant as the occu­
pant moves forward into the airbag .
A vehicle occ upant who is out of position and too
close to the a irbag gets in the way of an inflating
airbag. When an occupant is too close , he or she
will be struck violently and w ill receive serious or
possibly even fata l injury .
In order for the airbag to offer protect ion, it is
important that all vehicle occupants, especially
any children , who must be in the front seat be­
cause of exceptiona l circumstances, be properly
restrained and as far away from t he airbag as
poss ible. By keeping room between the child's ..,_

body and the front of the passenger compart­
ment, the airbag can inflate completely and pro­
vide supplemental protection in certain frontal
collisions.
.,&. WARNING
Not using a booster seat, using the booster
seat improperly, incorrectly installing a boos­
ter seat or using the vehicle safety belt im­
properly increases the risk of serious personal
injury and death in a collision or other emer­
gency situation. To help reduce the risk of se­
rious personal injury and/or death:
- The shoulder belt must lie as close to the
center of the child's collar bone as possible
and must lie flat and snug on the upper
body.
It must never lie across the throat or
neck. The lap belt must lie across the pelvis
and never across the stomach or abdomen .
Make sure the belt lies flat and snug. Pull on
the belt to tighten if necessary .
- Failure to properly route safety belts over a
child's body will cause severe injuries in an
accident or other emergency situation
¢ page 245.
-The rear side of the child safety seat should
be positioned as close as possible to the
backrest on the vehicle seat . 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
¢page 62. 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.
- Never let a child put the shoulder belt under
the arm or behind the back, because it could
cause severe injuries in a crash.
- Children on the front seat of any car, even
with Advanced Airbags, can be seriously in­
jured or even killed when an airbag inflates .
- Never let a child stand or kneel on any seat,
for example the front seat.
- Never let a child ride in the cargo area of
your vehicle.
- Always remember that a child leaning for­
ward, sitting sideways or out of position in
288
any way during an accident can be struck by
a deploying airbag. This will result in serious
personal injury or death .
- If you must install a booster seat on the
front passenger seat because of exceptional
circumstances the

Securing child seats
· Securing a child safety seat using a safety
belt
Safety belts for the rear seats and the front pas­
senger can be locked with the convertible locking
retractor to properly secure child safety seats.
The safety belts for the rear seats and for the
front passenger 's seat have a convertible locking
retractor for child safety seats . The safety belt
must be locked so that belt webbing cannot un­
reel. The retractor can be activated to lock the
safety belt and prevent the safety belt webbing
from loosening up during normal driving. A child safety seat can only be properly installed when
the safety belt is locked so that the child and
child safety seat will stay in place.
Always remember : Even though your vehicle is
equipped with an Advanced Airbag system, all
children, especially those 12 years and younger,
should always ride in the back seat properly re­
strained for their age and size .

· Activating the convertible locking retractor
Use the convertible locking retractor to secure a
child restraint.
Always heed the child safety seat manufacturer 's
instructions when installing a child restrain t in
your vehicle . To activate the convertible locking
retractor:
.. Place the child restraint on a seat, preferably
on the rear seat .
.. Slowly pull the belt
all the way out .
.. Route it around or through the child restraint
belt path
~ ,&. .
.. Push the child safety seat down with your full
weight to get the safety belt really tight.
.. Insert the belt tongue into the buckle for that
seating position.
.. Guide the safety belt back into the retractor un­
til the belt lies flat and snug on the child safety
seat.
.. You should hear a "clicking" noise as the belt
winds back into the inertia reel. Test the con ­
vertible locking retractor by pulling on the belt.
You should no longer be able to putt the belt
out of the retractor. The convertible locking re­
tractor is now activated .
.. Make sure that the red release button is facing
away from the child restraint so that it can be
unbuckled quickly.
.. Pull on the belt to make sure the safety belt is
properly tight and fastened so that the seat
cannot move forward or sideways more than
one inch (2 .5 cm) .
A WARNING
Using the wrong child restraint or an improp­
erly installed child restraint can cause serious
personal injury or death in a crash.

and disposal of the airbags on page 268.
Disconnecting the battery terminals
Some ve hicl e fu nctions (power window regula ­
tors, for examp le) are lost if the batte ry te rm i­
nals a re disconnected . These f unc tions have to be
relearned after the battery term inals are con­
nected again . To p revent this, the battery should
o nl y be disconnected from the vehicle electrical
system when absolute ly necessary for repairs.
Vehicles not driven for long periods
If you do not d rive yo ur vehicle ove r a period of
severa l days o r weeks, electr ica l components are
grad ua lly cut back or switched of f. T his reduces
