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 .

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 deact ivate this feature. If the
convert ible locking retractor is not deactivated,
the safety belt w ill gradually become tighter and
uncomfortable to wear.
_& WARNING
-
Improperly installed chi ld safety seats in­
crease the risk of serious personal injury and
death in a collision.

LATCH system (lower
anchorages and tethers
for children)
Child Restraint System anchors and how
are they related to child safety
To provide a simpler and more practicab le way to
attach the child restraint on the vehicle seat,
Federal regulations require special lower ancho­
rages in vehicles and devices on new child re­
straints to attach to the vehicle anchorages .
In the United States, the combination of the
tether anchorages and the lower anchorages is
now generally called the LATCH system for
"Lower Anchorages and Tethers for Children". In
Canada, the terms "top tether" with "lower uni­
versa l anchorages" (or "lower universal anchor­
age bars") are used to descr ibe the system .
In other countries the term "ISOFIX" is used to
describe the lower anchorages .
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 req uirements. These
new performance requirements make a tether
necessary on most new ch ild seats.
Installing a child restraint that requires a top
tethe r without one can seriously impair the per­
formance of the child restraint and its ab ility to
pro tect the child in a collision. Installing a child
restra int that requi res a top tether without the
top tether may be a violation of state law.
Child restraint manufacturers offer LATCH lower
anchorages on their child seats w ith hook-on or ..,.

Child safety
push-on connectors attached to adjustable
straps.
I n addition to the LATCH lower anchorages, these
chi ld restraint systems usually require the use of
tether straps to he lp keep the child restraint
firm ly in place.
A WARNING
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 veh icle.
- Never install a child restraint without a properly attached top tether strap if the
child restraint manufacturer's instruct ions
requ ire the top tether strap to be used.
- Improper use of child restra int LATCH lower
anchorage points can lead to injury in a colli­
s ion . The LATCH lower anchorage points a re
designed to withstand on ly those loads im­
posed by cor rect ly fitted child restraints .
- Never mount two child restraint systems on
one LATCH lower anchorage point.
- Never secure or attach any luggage or other
item to the LATCH lower anchorages.

Tether anchors and tether straps
Fig. 255 Tether anchors for second row of seats: attach·
ment hook locat ions
Fig. 256 Tet her anc hors for third row of seats: attachment
hook locat ions
The tether anchors for the rear seating positions
are located on the backside of the rear seatbacks.
A tether is a straight or V-shaped strap that at ­
taches the top part of a child restra int to specia l
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 inte­
rior .
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 safe ty seats.

feel resistance a second time.
Coolant loss usually indicates there is a leak . Im­
mediately drive your vehicle to an authorized
Audi dealer or authorized Aud i Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and being pushed out of the cooling system.
A WARNING
-The cooling system is under pressure. Do
not open the coolant expansion tank cap
when the eng ine is hot. This increases the
risk of burns .
- The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
