Installing a child safety
seat
Securing a child safety seat using a
safety belt
Safety belts for the rear seats and the front
passenger can be locked with the convertible
locking retractor to properly secure child
safety seats.
The safety belts emergency lock ing retractors
for the rear seats safety belts and for the
fro nt passenger's seat safety belt have a con­
vertible locking retracto r fo r child restra ints .
The safety belt must be locked so that belt
webbi ng cannot unreel. The retracto r can be
activ ated to lock t he safety be lt and p revent
t he safe ty belt webbing from loosening up
d uring normal driving . A child sa fety seat can
only be properly installed when the safety belt

is loc ked so that the chi ld and child sa fety
seat wi ll stay in place.
A lw ays remember: Even tho ugh yo ur vehicle is
equipped with an Advanced Airbag system, all
c hi ldren, especially those 12 years and young ­
er, sho uld always ride in the back seat prope r­
l y restrained for the ir age and size.
A WARNING
Imp roperly installed chi ld safety seats in­
crease the risk of serious personal injury
and death in a co llision.
- Always make sure that the safety belt re­
tracto r is locked when insta lling a child
safety seat. An unlocked safety belt re­
trac to r cannot hold the child safety seat
in place dur ing norma l dr iving o r in a
crash.
- Always buckle the child saf ety seat firmly
in place even if a ch ild i s not si tt ing in it.
A lo ose child safe ty seat can fly aroun d
du ring a sudden stop or in a collision .
- Always ma ke sure tha t the rear seat
backrest to which the center rear safety
belt is attached is securely latched when ­
eve r the rear center safety belt is being
used to secure a ch ild restra int .
- I f the backrest is not securely la tched,
the child and the child restraint will be
thrown forward togethe r with the bac k­
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 ca rrie rs on the front pas­
senger seat. A child will be serious ly in­
jured and can be killed when the passen­
ge r airbag inflates.

188 Child Safety
-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 177 . Special
precautions apply when installing a child
safety seat on the front passenger seat
c::;, page 155, Child restraints on the front
seat -some important things to know.
.&_ 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 164, 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 reg is- 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
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 de­ploy 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 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¢&_ .
.,. 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
Child Safety 189
seat cannot move forward or sideways more
than one inch (2.5 cm).
A 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 .

(D Note
If you leave the c hild restraint with the
tether strap firmly installed for several
days, th is could leave a mark on the up­
holstery on the seat cushion and backrest
i n the area where the tether strap was in­
stalled. The upholstery would also be per­ manently stretched around the tether
strap. This app lies especia lly to leather
seats.
Using tether straps on rearward-facing
child restraints
Currently, few rear-facing child restraint sys­
tems come with a tether. Please read and
heed the child restraint system manufactur­
er's instructions carefully to determine how to
properly install the tether .
A WARNING ,.;; -
A child in a rearward-facing ch ild safety
seat installed on the fron t passenger seat
will be ser io usly injured and ca n be killed if
the front airbag inflates -even with an Ad ­
vanced Airbag System.

temperature. This determines the current
state of charge and the power of the battery.
Idling current management
Idling current management reduces energy
consumpt ion while the vehicle is stand ing.
With the ignition switched off, it contro ls the
energy supply to the various e lectrica l compo ­
nents . Data from battery diagnosis is consid­
ered.
D epending on the battery's state of charge,
individua l consumers are gradua lly turned off
to prevent excessive discharge of the battery
and thus maintain starting capability.
Dynamic energy management
While the veh icle is being driven, dynamic en­
ergy management dist ributes the energy gen­
erated according to the needs of the individu­
a l components . It regu lates consumption, so
that more electrical energy is not being used
than is being generated and ensures an opti­
mal state of charge for the battery.
- But even energy management cannot negate the limits of physics. Consider
that the power and life of a battery are
limited.
- If starting ab ility is threatened, the indi­
cator light(•) appears
c> page 16, D
Battery.
What you should know
The highest priority is given to maintaining
starting capability .
The battery is severely taxed in short-distance
driving, in city traffic and during the co ld time
of year. Abundant electrical energy is re­
qu ired, but only a little is generated. It is also
cr itica l if the engine is not running and electri­
cal components are turned on. In th is in­
stance energy is being consumed but none is
be ing generated .
Intelligent technology 205
It is in precisely these situations that you will
notice energy management active ly regu lat­
ing the distribution of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks, e lectrica l compo­
nents are gradually cut back or switched off.
This reduces energy consumption and main­
tains starting capability over a longer period .
Some of the convenience functions may not
operate, such as the interior lights or the
power seat adjustment . The convenience
functions will be available again when you
switch on the ignition and start the eng ine.
With the engine turned off
If you listen to the radio, for example, with
the engine turned off or use other MMI func­
tions, the battery is being discharged.
If starting capability is jeopardi zed due to en­
ergy consumption, the following warning ap­
pears in the MM I display:
Please start the engine soon or the system
will be turned off.
The warning indicates that the system will be
turned off automatically after 3 minutes. If
you w ish to continue using the functions, you
have to start the engine.
With the engine running
Although electrical energy is generated when
the vehicle is being driven, the battery can be­
come discharged. This happens mostly when
li ttle energy is being generated and a great
deal consumed and the battery's state of
charge is not optimal.
T o b ring the energy ba lance back into equili­
brium, consumers wh ich requ ire espe cially
large amounts of energy are temporarily cut
back or switched off . Heating systems in par­
ticular require a great deal of energy. If you
notice, for examp le, that the heated seats* or
the heated rear window are not heating, they
have been temporarily cut back or switched .,.

210 Driving and environment
The consumption estimates as published
by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehi ­
cle load and speed, road and weather con­
ditions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
• Avoid unnecessary accelerating and braking.
Vehicles use the mo st fuel when they are ac­
celerating. If you anticipate what is going to happen next, you will need to brake less and,
thus , accelerate less. Let the vehicle coast
whenever possible -for example when you see
that the next traffic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
• Try and keep well below your car's maximum
speed .
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment .
Fuel consumption, exhaust emissions and en­
gine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
ditions permit.
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
• Shut the engine off when you are not driving
the vehicle. •
Do not warm up the vehicle by letting the
engine run at idle.
The idling phase is automatically reduced for
vehicles with the Start/Stop system. It is effi­
cient to switch off the engine in vehicles with­
out the Start-Stop-System when stopped at
railroad crossings and long red lights. Turning
the engine off for jus t 30-40 seconds saves
more fuel than is burned by starting the en-
. . gme again.
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions are especially high
when the engine is warming up . So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up.
W Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which could result in over­
heating or other damage to the vehicle or
other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
• Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
Audi dealer helps to ensure that it runs prop­
erly and economically. The condition of your
vehicle not only affects its safety and ability to
hold its value, it also affects
fuel consump­
tion.
Check your oil each time you
fill your tank.
The amount of oil used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven . ..,.
