LATCH system (lower
anchorages and tethers
for children)
Child Restraint System anchors and how
are they related to child safety
To p rovide a simp ler and mo re practicab le way to
attach the ch ild restraint on the vehicle seat,
Federal regulations require spec ia l lower ancho­
rages in vehicles and devices on new ch ild re­
straints to attach to the vehicle anchorages .
In the United States, the combination of the
tethe r ancho rages and the lower anchorages is
now generally called t he LATCH system for
" Lower Anchorages and Tethers for Children" . In
Canada, the terms
" top tet her" wi th "lower u ni­
versa l anchorages" (o r "lowe r universa l anchor­
age bars") a re used to des cribe the system .
In other co untries the term
"ISOFIX" is used to
desc ribe the lower anchorages .
Fo rward-facing chi ld restraints manufactured af­
ter September
1, 1999, are required by U.S . fed­
era l regulations to comply with new child head
movement performance req uir ements . These
new performance requ irements make a tether
necessary on most new ch ild sea ts.
Installing a ch ild restraint that requires a top
tether wi thout one can se riously impair the per­
fo rmance of the c hild rest raint and its ab ility to
pro tect the ch ild in a co ll ision. I nstalling a ch ild
r es trai nt th at r equi res a top te ther wi tho ut the
top tether may be a vio lation o f st ate law.

Fig. 172 Te the r ancho rs: att achm ent hook locatio ns be­
hi nd t he rea r seatbacks
The tether anchors for the two/three* rear seat­
ing positions are located on the backside of the
rear seatbacks
¢ fig. 172. Vehicles with two rear
seating positions are equipped with two tether
anchors.
A tether is a straight or V-shaped strap that at­
taches the top part of a child restraint to specia l
anchorage points in the vehicle.
The purpose of the te ther is to red uce the for­
ward movement of the child restraint in a c rash,
in order to he lp red uce the risk of head injury
that could be caused by striking the vehicle inte­ rior .
F orward 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 .
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 restra int you
intend to install in your Aud i.
- Improper use of child restra int anchors (in­

Cat alytic converter
The vehicle may only be driven w ith unleaded
gaso line, otherwise the catalytic converte r will be
dest royed.
Never dr ive until the tank is completely empty.
The irregular supply of fuel that results from that
can cause engine misfires. Uncombusted fuel will
enter the exhaust system, which can cause over­
heating and damage to the catalytic converter.
&_ WARNING
The temperat ure of the exhaust system is
h igh, both when drivi ng and a fter stopp ing
the engine.
-
- Never tou ch the exhaust tail pipes once they
have become hot. This cou ld resu lt in burns.
- Do not park your vehicle over flammable
materials s uch as grass or leaves because
the hig h temperature of the emissions con­
trol system could start a fire .
- Do not apply unde rbody protectant in the
exhaust system area, beca use this increases
