Tether anchors and tether straps
Fig. 178 Tethe r ancho rs: attachment hook locat io ns
behind the rea r sea tbacks
The tethe r anchors for the rear sea ting posi­
tions are located on the backside of the rea r
seatbacks
~ fig. 178.
A tether is a straight or V-shaped strap that
attaches the top part of a child restraint to
specia l anchorage points in the veh icle.
The purpose of the tether is to reduce the for·
ward movement of the ch ild restra int in a
crash, in order to he lp reduce the r isk of head
in ju ry that could be ca used by s tri king the ve­
hicle interior.
Forward facing child restra ints manufactured
after September 1, 1999, a re required by U .S .
federal regulations to comply with new child
head movement performance requirements.
These new performance requ irements make a
tether necessary on most new chi ld safety
seats.
A WARNING
Improper insta llation of chi ld restraints
w ill increase the risk of injury and death in
a crash.
- Always follow the instructions prov ided
by the manufacturer of the ch ild re­
st ra int you intend to install in your Audi.
- Improper use of c hild restra int anchors
(including tether anchors) can lead to in ·
jury in a co llision. Th e anchors are de·
sign ed to withstand only those loads im­
posed by cor rect ly fi tted ch ild restraints.
- Never mou nt two chi ld restraint systems
on one LA TCH lower anchor po int. -
Never attach two child restraint systems
to one tether strap or tether ancho rage.
- Never attach a tether strap to a tie-down
hook in the luggage compartment.
- Never use child restraint tether ancho­
rages to secure safety belts or other
kinds o f occupant restraints.
- Never secure or attac h any luggage or
other items to the LATCH lower ancho­
rages or to the tether anchors.

(D Note
When adding flu ids, always make sure that
they are poured into the proper conta iner
or f iller opening, otherwise serious dam­
age to vehicle systems w ill occur.
® For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regularly. If
you see spots from oil or other ve hicle flu­
i ds, have yo ur vehicle inspected by a n au­
thori zed Audi dea le r.
Closing the engine hood
.,. Pull the hood down un til the pressure from
t he struts is reduced.
.,. Let the hood drop down and latch in p lace .
Do not try to push it shut; it may fail to en­
gage ¢&_ .
A WARNING
-
A hood that is not completely latched
could fly up and b lock your view while dr iv­
ing.
- When you close the engine hood, check it
to make sure the safety catch has p roper­
ly engaged. The hood sho uld be flush
with the surrou nding vehicle body pa rts.
- If you notice while driv ing t hat the hood
is not s ecured prope rly, stop at onc e and
close it.

240 Tires and wheels
the driver observe the speci­
fied tire pressure values for
the tires and the correct pressures for the function of
the tire pressure monitoring
system.
-Always inflate tires to the
recommended and correct
tire pressure before driving
off.
-Driving with underinflated tires bend more, letting
them get too hot resulting
in tread separation, sudden
tire failure and loss of con­
trol.
-Excessive speed and/over­
loading can cause heat
build-up, sudden tire failure
and loss of control.
-If the tire pressure is too low or too high, the tires
will wear prematurely and
the vehicle will not handle
well.
-If the tire is not flat and you do not have to change a
wheel immediately, drive at reduced speed to the near­
est service station to check
the tire pressure and add air
as required.
(D Note
Driving without valve stem
caps can cause damage to
the tire valves. To prevent
this, always make sure that
factory installed valve stem
caps on all wheels are secure­ly mounted on the valve.
@ For the sake of the environment
Underinflated tires will also
increase the fuel consump­
tion.
Tires and vehicle load limits
There are limits to the amount
of load or weight that any vehi­
cle and any tire can carry. Ave­ hicle that is overloaded will not
handle well and is more diffi­
cult to stop. Overloading can
not only lead to loss of vehicle
control, but can also damage
important parts of the vehicle
and can lead to sudden tire fail­
ure, including a blowout and
sudden deflation that can cause
the vehicle to crash.
Your safety and that of your passengers also depends on
making sure that load limits are~

254 Tire s and wheel s
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the
factory installed rims. If different rims are fit­
ted, the correct wheel bolts with the r ight
length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
secure ly and that the brake system funct ions
correctly .
In ce rtain circumstances, you may not use
wheel bolts from a different vehicle -even if it
i s the same mode l
~page 284.
_& WARNING
Improperly tig htened o r maintained whee l
bolts can become loose ca using loss of
contro l, a co llision and serious persona l in­
jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­
erly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can
become loose while driving if greased or
oiled, even if tightened to the specif ied
torque.
- Only use wheel bolts that belong to the
rim being installed.
- Never use different wheels bolts on your
vehicle.
-Always maintain the correct tighten ing
torque for the wheel bo lts to reduce the
risk of a wheel loss. If the tightening tor­
que of the wheel bolts is too low, they
can loosen and come out when the veh i­
cle is moving. If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel can be­
come loose.
@ Note
The spec ified torque fo r the wheel bo lts is
90 ft lb (120 Nm) w ith a tolerance of± 7,4
ft lb(± 10 Nm). Torque wheel bo lts diago- nally
. After changing a whee l, the torque
must be checked as soon as possible with a
torque wrench -preferably by an author­
i zed Audi dealer or qualified workshop.
Low aspect ratio tires
Your Audi is factory-equ ipped w ith low aspect
ratio tires . These tires have been thoroughly
tested and been selected specifically fo r your
model for their superb perfo rmance, road fee l
and hand ling under a variety of d riving cond i­
tions . As k your au thor ized A udi dealer for
more details .
T he low aspect ratio of these tires is ind icated
by a numera l of
55 or less in the tire's s ize
designation. The numera l represen ts the ratio
of the tire's sidewall height in relation to its
tread width expressed in percentage . Conven­
tiona l tires have a height/width ratio of 60 or
more.
The perf orm ance of low- aspect-r atio tire s is
p ar ticu larly s ensitive to improper infl ati on
press ure . It is t here fore im portant that low
as pect rat io tires are infl ated to the spe cified
pre ssure and that the infl ation pressu re is
r e gularl y che ck e d and mainta in ed. Tire pre s­
su res should b e check ed at least onc e a
month and alwa ys bef ore a long trip
~page 237, Checking tire pressure.
What you can do to a void tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact w it h potholes, curbs, gull ies
o r r idges on the road, pa rticularly if the tire is
u nderinfla ted .
In order to minimize the occurrence of impact
damage to the tires of you r vehicle, we recom­
mend that you observe the follow ing p recau­
tions:
- Always ma inta in recommended inflation
pressures. Check your tire pressure eve ry
2,000 miles (3,000 km) and add air if neces­
sary .
- Dr ive carefully on roads with potholes, deep
gullies o r ridges. The impact from dr iv ing ..,.
