Child safety
-Never put the forward-facing child restraint
up, against or very near the instrument pan­
el.
- 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.
- Make sure that the
PASSENGER AIR BAG
OFF~ ;
light comes on and stays on all the
time whenever the ignition is switched on.
A 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 Ad­
vanced 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 in­
stall a rearward facing child safety seat on
the front passenger seat in exceptional cir­
cumstances .
- 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
install the rear-facing child safety seat in a
rear seating position and have the airbag
system inspected by your Audi dealer .

· 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.
- Always make sure that the safety belt re­
tractor is locked when installing a child
safety seat. An unlocked safety belt retrac­
tor 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.

Using tether straps on rearward-facing
child restraints
Currently, few rear-facing chi ld restraint systems
come with a tether. Please read and heed the
child restraint system manufacturer's instruc­
tions carefully to determine how to properly in­
stall the tether.
A WARNING
A child in a rearward-facing child safety seat
installed on the front passenger seat will be
ser iously injured and can be killed if the front
airbag inflates -even w ith an Advanced A irbag
System.
- T he inflating a irbag w ill 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, or
door.
- If you must install a rearward facing child
safety seat on the front passenger seat be­
cause of exceptiona l circumstances and the
PASSENGER AIR BAG OFF,;; light does not
come on and stay on, immed iate ly install
the rear-facing child safety seat in a rear
seat ing pos ition and have the airbag system
inspected by your Audi dealer.

General information
Unde r normal operating conditions, the battery
i n your Audi does not need any maintenance.
W ith

d rives we recommend that you have the electro­
lyte leve l checked by an a uth orized Audi dea le r or
qua lified wor kshop. The e lectroly te leve l should

Have t he battery chec ke d when yo u take yo ur ve ­
hicle in for service . You are we ll advised to re­
place a battery that is o lder than 5 yea rs .
With ce rta in types o f airbag deployment, t he
b atte ry is disconnected from the veh icle elect ri­

in Repair, care
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
energy consumpt ion and maintains start ing ca­
pability over a longer period ¢
page 138.
Some of the convenience functions may not oper­
ate, such as the inter ior lights or the power seat
adjustment . The convenience functions will be
available again w hen you turn on the ignit io n and
start the eng ine .

Dur ing the winte r months, battery capacity tends
to decrease as tempe ratures drop. This is be ­
ca use more power is also consumed while start­

etc ., are used more often.
Avo id unnecessary powe r consumption, partic u­
l a rly in city traffic or when traveling o nly short
distances . Let your author ized Audi dealer check
the capacity of the vehicle battery before win ter
sets in ¢
page 314 . A well charged battery will
n ot only p reve nt sta rting prob lems when the
we ather is co ld , but will also last longer.
