child restraint on the front passenger's
seat in exceptional situations:
- Whenever a forward or rearward-facing
child restraint is installed on the front
passenger seat, the
PASSENGER AIR
BAG OFF
light must come on and stay on
whenever the ignition is switched on .
-If the PASSENGER AIR BAG OFF light
does not come on and stay on, perform
the checks described
~ page 141, Moni­
toring the Advanced Airbag System .
- Take the child restraint off the front pas­
senger seat and install it properly at one
of the rear seat positions if the
PASSEN·
GER AIR BAG OFF
light does not stay on
whenever the ignition is switched on.
- Improper installation of child restraints
can reduce their effectiveness or even
prevent them from providing any protec­
tion.
- An improperly installed child restraint
can interfere with the airbag as it de­
ploys and seriously injure or even kill the
<;hild.
- Always carefully follow the manufactur­
er's instructions provided with the child
safety seat or carrier.
- Never place additional items on the seat
that can increase the total weight regis­
tered by the weight-sensing mat and can cause injury in a crash.
_&. WARNING
Forward-facing child restraints:
- Always 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.
- Never put the forward-facing child re·
straint up, against or very near the in­
strument panel.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible before installing
the forward-facing child restraint. The
Child Safety 163
backrest must be adjusted to an upright
position.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched
on .
_&. WARNING
"' Rearward-facing child restraints:
-A child in a rearward-facing child safety
seat installed on the front passenger
seat will be seriously injured and can be
killed if the front airbag inflates - even
with an Advanced Airbag System .
- The inflating airbag will hit the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the backrest, center
armrest, door or roof.
-Always be especially careful if you must
install a rearward facing child safety seat
on the front passenger seat in exception­
al circumstances.
-A tight tether strap on a rearward-facing
child restraint attached to the front pas­
senger seat can put too much pressure
on the weight-mat in the seat and regis­
ter a heavier weight in the Advanced Air­ bag System. The heavier weight regis­
tered can make the system work as
though an adult were on the seat and de­
ploy the Advanced Airbag when it must
be suppressed causing serious or even
fatal injury to the child.
- 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, immedi­
ately install the rearward-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer. •

164 Child Safety
Activating the convertible locking retractor
Use the convertible locking retractor to se­
cure a child restraint.
Always heed the child safety seat manufactur­
er's instructions when installing a child re­
straint in your vehicle. To activate the conver­
tible locking retractor:
• Place the child restraint on a seat, prefera­
bly on the rear seat.
• Slowly pull the belt
all the way out.
• Route it around or through the child re­
straint belt path¢.&_ .
• Push the child safety seat down w ith 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
until 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
convertible locking retractor by pulling on
the belt. You should no longer be able to
pull the belt out of the retractor. The con­
vertible locking retractor is now activated.
• Make sure that the red release button is fac­
ing away from the child restraint so that it
can be unbuckled quickly .
•Pullon 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).
.&_ WARNING
Using the wrong child restraint or an im­
properly installed child restraint can cause
serious personal injury or death in a crash.
- Always make sure that the safety belt re-
tractor is locked when installing a child
safety seat. An unlocked safety belt re­
tractor cannot hold the child safety seat in place during normal driving or in a
crash .
- Always buckle the child safety seat firmly
in place even if a child is not sitting in it.
-
A loose child safety seat can fly around
during a sudden stop or in a crash.
- Always make sure the seat backrest to
which the child restraint is installed is in
an upright position and securely latched
into place and cannot fold forward. Oth­
erwise, the seatback with the child safety
seat attached to it could fly forward in
the event of an accident or other emer­
gency situation.
- Always read and heed all WARNINGS
whenever using a child restrained in ave­
hicle is being used
¢page 152. Special
precautions apply when installing a child
safety seat on the front passenger seat
¢ page 132, Child restraints on the front
seat -some important things to know.
'
Deactivating the convertible locking
retractor
T he convertible locking retractor for child re­
strain ts will be deactiva ted automatically
when the bel t is wound all the way back in to
the retractor .
• Press the red button on the safety belt buck­
le . The belt tongue will pop out of the buck­
le .
• Guide the safety belt all the way back into
its stowed position .
Always let the safety bel t retract completely
into its stowed position . The safety belt can
now be used as an ordinary safety belt with­
out the convertible locking retractor for child
restraints.
If the convertible locking retractor should be
activated inadvertently, the safety belt must be unfastened and guided completely back in­
to its stowed position to deactivate this fea­
ture. If the convertible locking retractor is not
deactivated , the safety belt will gradually be-
come tighter and uncomfortable to wear.

212 Tires and wheels
-If you notice unusual vibra­
tion or if the vehicle pulls to
one side when driving, al­
ways stop as soon as it is
safe to do so and check the
wheels and tires for dam­
age.
0 Note
-Please note that summer and winter tires are de­
signed for the conditions
that are typical in those sea­
sons. Audi recommends us­
ing winter tires during the
winter months. Low tem­ peratures significantly de­
crease the elasticity of
summer tires, which affects
traction and braking ability. If summer tires are used
in
very cold temperatures, cracks can form on the tread
bars, resulting in perma­
nent tire damage that can
cause loud driving noise and
unbalanced tires. Audi is not
responsible for this type of
damage.
-Burnished, polished or chromed rims must not be used in winter road condi­
tions. The surface of the
rims does not have suffi­
cient corrosion protection
for this and could be perma­
nently damaged by road salt
or similar substances.

tory-installed equipment (whether installed or not).
Aspect ratio
