176 Child Safety
younger, should always ride in the back seat properly restrained for their age and size.
A WARNING
Improperly installed child safety seats in­
crease the risk of serious personal injury
and death in a collision .
-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 collision.
- Always make sure that the rear seat
backrest to which the center rear safety
belt is attached is securely latched when­
ever the rear center safety belt is being
used to secure a child restraint.
- If the backrest is not securely latched,
the child and the child restraint will be
thrown forward together with the back­ rest and will strike parts of the vehicle
interior. The child can be seriously in­
jured or killed.
- Never install rear-facing child safety
seats or infant carriers on the front pas­ senger seat . A child will be seriously in­
jured and can be killed when the passen ­
ger airbag inflates .
- 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 install rear-facing child safety
seats or infant carriers on the rear seat.
- Forward-facing child safety seats or in­
fant carriers installed on the front pas­
senger's seat may interfere with the de­
ployment of the airbag and cause serious
injury to the child.
- It is safer to install a forward-facing
child safety seat on the rear seat. -
Always read and heed all WARNINGS
whenever using a child restrained in ave­
hicle is being used
c> page 166. Special
precautions apply when installing a child
safety seat on the front passenger seat
c:> page 144, Child restraints on the front
seat -some important things to know.
A WARNING
-
Always take special precautions if you
must install a forward or rearward-facing
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
c> page 153, 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
child.
- 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.
A 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
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.
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 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 .
Child Safety 177
-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 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 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
¢ _A .
.. 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
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 .
.. 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). .,._

Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
te cts the engine from freezing in the winter .
The cooling system is sealed and generally re­
qu ires little attention .
The cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly ­
col-based coolant additive G13 ant ifreeze
w ith anticorrosion add itives (SO% fo r USA
models; 60% for Canad ian models). This mix­
ture bot h assu res the ne cessary frost protec­
tion and protects metal components in the
engine's coo ling system from corrosion and
scaling. It also raises the boili ng po int of t he
coolant.
D o not red uce the concentration o f the coo l­
ant in the summer by adding plain water .
The
proportion of coolant addit ive must be at
least 50% but not mo re than 60 %
to main­
tain antifree ze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant cou ld freeze and damage the veh i­
cle heating and eng ine cooling system .
For year-round driving, antifree ze is added at
the factory for temperatures down to:
- -3 1°F (-3S°C)USA
- -40 ° F ( - 4 0 °C) Canada.
