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
r ages 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.

A WARNING
Improper installation of c hild 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 veh icle.
- Never install a child restra int w ithout a
properly attached top tether strap if the
child restraint ma nufacturer's instruct ions
requ ire the top tether strap to be used .
- Improper use of child restra int LATC H lower
anchorage po ints can lead to injury in a colli ­
sion . The LATCH lower anchorage points a re
designed to withstand only those loads im­
posed by correc tly fi tted child res traints .
- N ever mount two chi ld restraint systems on
one LATCH lower a nchorage poin t.
- Never secure or attach a ny luggage or other
item to the LA TCH lower anc horages .

¢ fig . 170
A tether is a stra ight or V-shaped strap that at­
taches the top part of a child restra int to special
anchorage points in the vehicle.
The purpose of the tether is to red uce the for­
ward movement of the child res tra int in a crash,
in order to help red uce the risk of head injury
that could be caused by striking the veh icle inte­
rio r.
F orward facing ch ild res traints manufactured af ­

eral regulations to comply with new child head
movement performance requirements. These
new perfo rmance r equirements make a tether

A WARNING
Improper installation of child restraints will

-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
cluding tether anchors) can lead to injury in
a collision . The anchors are designed to
withstand only those lo ads imposed by cor­
rectly fitted child restra ints.
-Never mount two chi ld restraint systems on
one LATCH lower a nchor po int.
Ch ild s afe ty
-Never attach two child restraint systems to
one tether strap or tether anchorage.
-Never attach a tether strap to a tie-down
hook in the luggage compartment.
-Never use child restraint tether anchorages
to secure safety be lts or other kinds of occu­
pant restraints.
-Never secure or attach any luggage or other
items to the LATCH lower anchorages or to
the tether anchors.
-If you must install a rearward facing child
safety seat on the front passenger seat be­
cause of exceptional circumstances and the
PAS SENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rear-facing child safety seat in a rear seating position and have the a irbag system
inspected by your Audi dealer.

Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate. This is especially important
when driving in colder climates.
- If the appropriate coolant additive is not

Observe the safety precautions~ page 189,
Working in the engine compartment .
Checking the engine coolant level
• Park the vehicle on a leve l surface .
• Switch the ignition off.
• Read the coolan t leve l on the coo la nt expansion
tank~ page 192, fig . 179. The coolant level
must be between the MIN and MAX markings
196
when the engine in cold. When the engine is
warm it can be slightly above the MAX marking .
Adding coolant Requirement: there must be a residual amount of
coolan t in the expansion tan k
~CD -
• Let the engine cool down .
• Place a cloth over the coolant expansion tank
cap and unscrew the cap counterclockw ise
~ & -
... Add coo lant m ixed in the cor rect ratio
~ page 195 up to the MAX marking.
• Make sure that the fluid level remains stab le .
Add more coolant if necessary .
• Close the cap securely.
Coolant loss usually ind icates there is a leak . Im­
mediate ly drive your vehicle to an authorized
Audi dealer or authorized Audi Service Fac ility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheat ing
and being pushed out of the cooling system .
A WARNING
- The cooling system is under pressure. Do
not open the coo lant expansion ta nk cap
when the engine is hot. This increases the
risk o f bur ns.
- The coolan t addi tive and the coolant can be
dangerous to your health. For t his reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
(D Note
Do not add coolant if the expansion tank is
empty. A ir cou ld enter the cooling system and
damage the engine. If this is the case, do not
continue driving. See an authorized Audi deal­
er or authorized Audi Serv ice Facility for assis­
tance.

stances should it be used to lift heavy
vehicles or other loads; you risk injuring
yourself.
