Tether anchors and tether straps
Fig. 132 Tether anchors: attachment hook locations be­
hi nd the rear seatbac ks
The tether anchors for the rear seat ing positions
are located on the backside of the rear seatbacks
¢ fig. 132.
A tether is a straight or V-shaped strap that at­
taches the top par t of a ch ild restrain t to special
anchorage points in the vehicle .
The purpose of the tether is to reduce the for­
ward movement of the child restrain t in a crash,
i n order to help reduce the risk of head injury
that cou ld be caused by striking the vehicle inte­
rior.
Forward facing child restra ints manufac tured af­
te r September 1, 1999, are requi red by U.S . fed­
era l reg ulations to comply with new child head
movement performance req uirements . These
new performance requ irements make a tether
necessary on most new child safety seats.
A WARNING
Improper installation of child restra ints w ill
increase the risk of injury and death in a
crash .
- Always follow t he i nstructions provided by
the manufacturer of the ch ild restraint you
intend to i nstall in your Audi.
- Improper use of chi ld restraint anchors ( in­
cluding tether anchors) can lead to injury in
a co llision . The anchors are designed to
w it h stand on ly those loads imposed by cor­
re ctly fi tted ch ild restraints.
- Never mo unt two ch ild rest raint systems on
one LA TC H l owe r anchor point.

-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 belts or other kinds of occu­
pant restraints.
- Never secure or attach any luggage or other
items to the LA TCH lower anchorages or to
the tether anchors.
- If a 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
causes the weight-sens ing 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 dep loy the Ad­
vanced Airbag when it must be supp ressed
ca using se rious o r even fatal injur y to the
c hild.
- If you must install a re arward fac ing ch ild
safety seat on the front passenger seat be­
cause of except io na l circumstances and the
PASSENGER AIR BAG O FF light does not
come on and stay on, immediate ly install
the rear-fac ing child safety seat in a rear
seating position and have the airbag system
inspected by your Audi dealer.

le ase it from the anchorage.
(D Note
If yo u leave the child restrai nt w ith the tethe r
strap firmly i nstalled for several days, th is
could leave a mark on the uphols tery on the
seat cushion and backrest i n the area where
the tether strap was installed. The upholstery

~ Add coolant mixed in the correct ratio
¢ page 166 up to the upper marking.
~ Make sure that the fluid level rema ins stable.
Add more coolant if necessary.
~ Close the cap securely.
Coolant loss usually indicates there is a leak. Im­
mediately drive your vehicle to an authorized
Audi dealer or authori zed Audi 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 be ing pushed out of the cooling system.
.&, WARNING
The cool ing system is pressu rized and can be­
come very hot. To reduce the r is k of burns
from hot coolant :
- Do not open the coo lant expansion tank cap
when the engine is hot. This increases the risk of burns.
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from es -
caping coolant and steam by covering the
coolant tank cap with a large, thick cloth .
- T urn the coo lant tank cap co unterclo ckwise
slowly and keep light pressu re on the cap .
- T o reduce the risk of burns , do not allow any
antifreeze o r coolant to drip onto the ex­
haust system or hot engine components.
T he ethylene glycol in engine coolant can
catch fire under certain circumstances .
- T he coo lant add itive and the coolant can be
dangerous to your health . For this 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 .
Do not add coolant if the expansion tank is
empty. Air could enter the cooling system and
damage the engine. If this is the case, do not
cont inue driv ing . See an authorized Audi deal -
Check ing and Filling
er or authorized Aud i Service Facility for assis ­
tance .
- Before the start of winter, have your author­
ized Aud i dea ler or a uthorized Audi Serv ice
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 appropr iate coo lant add itive is not
availab le in an emergency, do not add any
other additive . You could damage the en­
gine. If this happens, only use water and re­
store the correct m ixtu re ratio with the
specified coolant add it ive as soo n as poss i­
ble .
- Only refill w ith new coolant.
- Radiator sealant must not be mixed with
the coolant .
Radiator fan
T he radiator fan switches on automatically by it ­
self.
An auxiliary e lectr ic radiator fan switches on and
off depend ing on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fan c a n continue running for up to 10 m inutes - even
with the ignition off . It can even switch on aga in
later by itself ¢.& , if
- the temperature of the engine coolant rises due
to the heat build-up from the engine in the en­
gine compartment, or
- the engine compartment heats up bec ause the
veh icle is parked in in tense sunlight.
.&, WARNING
--
- To reduce the r isk of personal injury never
touch the radiator fan .
- The auxiliary e lectr ic fan is temperature
controlled and can switch on s uddenly even
when the engine is not runn ing .
- The auxiliary radiator fan sw itches on auto ­
mat ica lly when the eng ine coolant reaches a
certa in temperature and will continue to run
until the coolant temperature d rops .
