Child safety


ZA\ WARNING
Always take special precautions if you must
install a forward or rearward-facing child re-
straint on the front passenger's seat in excep-
tional situations:
— Whenever a forward or rearward-facing
child restraint is installed on the front pas-
senger 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 198, Monitoring
the Advanced Airbag System.
— If the PASSENGER AIR BAG OFF %; light
does not come on and stay on whenever the
ignition is switched on 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. Have the air-
bag system inspected immediately by your
Audi dealer.
— Improper installation of child restraints can
reduce their effectiveness or even prevent
them from providing any protection.
— An improperly installed child restraint can
interfere with the airbag as it deploys and
seriously
injure or even kill the child.
— Always carefully follow the manufacturer's
instructions provided with the child safety
seat or carrier.
— After checking to make sure that the child
restraint is properly installed, make certain
that the child restraint is correctly recog-
nized by the capacitive passenger detection
system in the front passenger seat and that
the PASSENGER AIR BAG OFF %; light sig-
nals the correct front passenger frontal air-
bag status.


ZA\ WARNING
Forward-facing child restraints:
— Always make sure the forward-facing seat
has been designed and certified by its manu-
facturer for use on a front seat with a pas-
senger front and side airbag.

— Never put the forward-facing child restraint
up, against or very near the instrument pan-
el
— Always move the passenger seat into its
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. The backrest
must be adjusted to an upright position.
— Make sure that the PASSENGER AIR BAG
OFF 3%; light comes on and stays on all the
time whenever the ignition is switched on.

ZA 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, have the air-
bag 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 restraint in
your vehicle. To activate the convertible locking
retractor:
> Place the child restraint on a seat.
> Slowly pull the belt all the way out.
221

Child safety

> Route it around or through the child restraint
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 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 pull 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 and sideways more than
lin (2.5 cm).

ZA 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 retrac-
tor is locked when installing a child safety
seat. An unlocked safety belt retractor can-
not 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 ina crash.
— Always make sure the seat backrest to which
the child restraint is installed is in an up-
right position. Otherwise, the seatback with
the child safety seat attached to it could fly
forward in the event of an accident or other
emergency situation.
— Always read and heed all WARNINGS when-
ever using a child restrained in a vehicle is
being used = page 211. Special precautions
apply when installing a child safety seat on
the front passenger seat > page 188, Child

222

restraints on the front seat - some impor-
tant things to know.
Deactivating the convertible locking
tela tel
The convertible locking retractor for child re-
straints will be deactivated automatically when
the belt is wound all the way back into the re-
tractor.

> Press the red button on the safety belt buckle.
The belt tongue will pop out of the buckle.
>» Guide the safety belt all the way back into its
stowed position.
Always let the safety belt retract completely into
its stowed position. The safety belt can now be
used as an ordinary safety belt without the con-
vertible locking retractor for child restraints.
If the convertible locking retractor should be ac-
tivated inadvertently, the safety belt must be un-
fastened and guided completely back into its
stowed position to deactivate this feature. If the
convertible locking retractor is not deactivated,
the safety belt will gradually become tighter and
uncomfortable to wear.

ZA\ WARNING
Improperly installed child safety seats in-
crease the risk of serious personal injury and
death in a collision.
— Never unfasten the safety belt to deactivate
the convertible locking retractor for child re-
straints while the vehicle is moving. You
would not be restrained and could be seri-
ously injured in an accident.
— Always read and heed all WARNINGS when-
ever using a child restrained in a vehicle is
being used > page 211. Special precautions
apply when installing a child safety seat on
the front passenger seat > page 188, Child

Fig. 172 Tether strap: proper routing and mounting (Ver-
sion B)
The tether strap anchor bracket is located behind
the front passenger's seat at the rear panel to
the engine compartment.
A tether is a straight or V-shaped strap that at-
taches the top part of a child restraint to special
anchorage points in the vehicle.
The purpose of the tether is to reduce the for-
ward movement of the child restraint in a crash,
in order to help reduce the risk of head injury that
could be caused by striking the vehicle interior.
Forward facing child restraints manufactured af-
ter September 1, 1999, are required by U.S. fed-
eral regulations to comply with new child head
movement performance requirements. These
new performance requirements make a tether
necessary on most new child safety seats.
Installing a child restraint that requires a top
tether without one can seriously impair the per-
formance of the child restraint and its ability to
protect the child in a collision. Installing a child

restraint that requires a top tether without the
top tether may be a violation of state law.

Improper installation of child restraints will
increase the risk of injury and death in a crash.
— Always follow the instructions provided by
the manufacturer of the child restraint you
intend to install in your Audi.
— Improper use of child restraint anchors (in-
cluding tether anchors) can lead to injury in
a collision. The anchors are designed to
withstand only those loads imposed by cor-
rectly fitted child restraints.
— Never attach two child restraint systems to
one tether strap or tether anchorage.
— Never use child restraint tether anchorages
to secure safety belts or other kinds of occu-
pant restraints.
— Never secure or attach any luggage or other
items to the tether anchors.
— Ifa tether or other strap is used to attach a
child restraint to the front passenger seat,
make sure that it is not so tight, that it caus-
es the weight-sensing mat to measure more
weight than is actually on the seat.
— The heavier weight registered can make the
Advanced Airbag System work as though an
adult were on the seat and deploy the Ad-
vanced Airbag when it must be suppressed
causing serious or even fatal injury to the
child.
— Never install a rearward facing child safety
seat on the front passenger seat unless the
PASSENGER AIR BAG OFF %; light comes
on and stays on. If the PASSENGER AIR
BAG OFF 3%; light does not come on and stay
on the inflating airbag will hit the child safe-
ty seat or infant carrier with great force and
will smash the child safety seat and child
against the backrest, door or roof. Have the
airbag system inspected immediately by
your authorized Audi dealer.
— Never install a child restraint without a
properly attached top tether strap if the
child restraint manufacturer's instructions
require the top tether strap to be used.

Child safety

Installing the tether strap on the
anchorage
Applies to: vehicles with Tether anchors and tether straps
Installing the tether strap
> Release or deploy the tether strap on the child
restraint according to the child restraint manu-
facturer's instructions.
> Guide the upper tether strap sideways (Version
A) > page 223, fig. 171 or under (Version B)
=> page 223, fig. 172 the head restraint.
> Remove the cover to expose the anchor bracket.
> Attach the tether strap anchorage hook into the
opening of the tether anchorage.
> Pull on the tether strap hook so that the spring
catch of the hook is engaged.
> Tighten the tether strap firmly following the
child restraint manufacturer's instructions.
Releasing the tether strap
> Loosen the tension following the child restraint
manufacturer’s instructions.
> Depress the spring catch on the hook and re-
lease it from the anchorage.
©) Note
If you leave the child restraint with the tether
strap firmly installed for several days, this
could leave a mark on the upholstery on the
seat cushion and backrest in the area where
the tether strap was installed. The upholstery
would also be permanently stretched around
the tether strap. This applies especially to
leather seats.
Using tether straps on rearward-facing
Riera)
Applies to: vehicles with Tether anchors and tether straps
Currently, few rear-facing child 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.

Z\ WARNING
A child in a rearward-facing child safety seat
installed on the front passenger seat will be

224

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 or
door.
— Never install a rearward facing child safety
seat on the front passenger seat unless the
PASSENGER AIR BAG OFF 3; light comes
on and stays on. If the PASSENGER AIR
BAG OFF ¥; light does not come on and stay
on the inflating airbag will hit the child safe-
ty seat or infant carrier with great force and
will smash the child safety seat and child
against the backrest, door or roof. Have the
airbag system inspected immediately by
your authorized Audi dealer.

Checking and Filling



— Never open the cap on the coolant expan-
sion tank when the engine is warm. The
cooling system is under pressure.
— To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
thick cloth when opening.
— Do not remove the engine cover under any
circumstances. This increases the risk of
burns.
— Due to the risk of electric shock, never touch
the ignition cable or other components in
the electronic high-voltage ignition system
when the engine is running or is starting.
— If a gear is engaged while the vehicle is sta-
tionary and the engine is running, do not
press the accelerator pedal inadvertently.
Pressing the accelerator pedal will cause the
vehicle to move, and this could result in an
accident.
— If inspections or repairs must be performed
while the engine is running, moving compo-
nents (such as the ribbed belt, generator,
and radiator fan) pose an additional risk.
— Set the parking brake first and select the
“p” (Park) selector lever position.
— Always make sure that no parts of the
body, jewelry, ties, loose clothing, and
long hair can be caught in moving engine
components. Before any work, always re-
move any jewelry and/or ties, tie back long
hair, and make sure all clothing fits close
to the body to reduce the risk of anything
becoming caught in engine components.
— Pay attention to the following warnings list-
ed when work on the fuel system or on the
electrical equipment is required.
— Do not smoke.
— Never work near open flames.
— Always have a working fire extinguisher
nearby.
— All work on the battery or electrical system
in your vehicle can result in injuries, chemi-
cal burns, accidents, or burns. Because of
this, all work must be performed only by an
authorized Audi dealer or authorized Audi
Service Facility.
— Limit your exposure to exhaust and chemi-
cals to as short a time as possible.

Driving in other
countries
Government regulations in the United States and
Canada require motor vehicles to comply with
emissions regulations and safety standards.
Therefore, vehicles that were produced for the
U.S. and Canadian markets are different from ve-
hicles produced for other countries.
If you plan to use your vehicle outside of the
United States or Canada, it is possible that:
— Fuel may have a significantly lower octane rat-
ing. Unsuitable fuels can cause engine damage.
— Proper maintenance and repair work may not
be possible because special service equipment,
tools, or measuring devices needed for your ve-
hicle may not be available.
284
— Replacement parts may not always be availa-
ble.
— Navigation systems for vehicles built for the
U.S.A. and Canada will not necessarily work in
Europe, and may not work in other countries.

and technical modifi-
cations
Note the safety precautions > page 229, General
information and > page 275, Raising the vehicle.
General information
Due to the increasing complexity of technology in
these vehicles, as well as the safety and environ-
mental standards that apply, you can only per-
form a very limited amount of repairs and modifi-
cations to the vehicle yourself.
Proof of maintenance work may be required to
submit a claim within the warranty period.
We recommend that you have your vehicle serv-
iced by an authorized Audi dealer or authorized
Audi Service Facility and that Audi Genuine Parts
and Audi Genuine Accessories are used. This
helps to ensure that your vehicle's functionality,
performance, and safety are not impaired.
Maintenance and repairs
Your vehicle was designed to help keep mainte-
nance requirements to a minimum. Some regular
maintenance is required to help ensure that your
vehicle runs in a safe, economical, and reliable
manner. Please refer to your Warranty & Mainte-
nance Booklet for more detailed information
about vehicle maintenance.
When operating the vehicle under more extreme
operating conditions, for example when outside
temperatures are very low or in very dusty envi-
ronments, certain maintenance should be per-
formed between the specified intervals.
