Tether anchors and tether straps
Fig. 174 Te the r ancho rs: att achm ent hook locatio ns be­
hi nd the rea r seatbacks
The tether anchors for the two/three* re ar seat­
ing positions are located on the backside of the
rear seatbacks
¢ fig. 174. 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 special
anchorage points in the vehicle.
The purpose of the tether is to red uce the for­
ward movement of the child restraint in a crash,
in order to he lp reduce 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
cl uding tethe r anchors) ca n l ead to inj ury in
a collision. The anchors are designed to
withstand only those lo ads imposed by cor­
rectly f itted child restraints .
Child sa fety
- Never mount two child restraint systems on
one LATCH lower 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 compa rtment.
- 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 rea r-facing child safety seat in a rear
seating position and have the a irbag system
i n spe cted by your Audi dea ler.

Installing the tether strap
.,. Release or deploy the tether strap on the child
restraint according to the ch ild rest raint manu­
facture r's instr uctions .
.,. Guide the upper te ther s trap under or s ideways
of the rear head restraint~
fig. 175 (dependi ng
on the chi ld restraint).
.. Attach the tether strap anchorage hook into
the tether anchorage.
.,. Pull on the tether strap hook so that the spring
catch of the hook engages .
.,. Tighten the tether strap firmly following the
child restra int manufacture r's instructions . .,.

Child safety
Releasing the tether strap
.,. Loosen the tension following the child restraint
manufacturer's instructions.
.,. Depress the spring catch on the hook and re­
leas e it from the anchorage.
(D Note
If you leave the child restraint with the tether
strap firmly installed for several days, this
could leave a mark on the upholstery on the
seat cushion and backrest in the area where
the tether strap was installed. The upholstery
would also be permanently stretched around the tether strap . This applies especially to
leather seats.
Using tether straps on rearward-facing
child restraints
Currently, few rear-facing child restraint systems
come with a tether. Please read and heed the
child restraint system manufacturer's instruc­
tions carefully to determine how to properly in­
stall the tether.
A WARNING
A child in a rearward-facing child safety seat
installed on the front passenger seat will be
seriously injured and can be killed if the front
airbag inflates -even with an Advanced Airbag
System.
- The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child
against the backrest, center armrest, or
door.
- If you must install a rearward facing child
safety seat on the front passenger seat be­
cause of exceptional circumstances and the
PASSENGER 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 airbag system
inspected by your Audi dealer.

\.J ' Using the proper engine oil is important for the
functionality and s ervice life of the engine. Your
engine was factory-filled with a high -quality oil
which can usually be used throughout the entire
yea r.
Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions d ue to failure
to follow rec ommended maintenance and use
requireme nts as s et forth in the Audi Owner's
Manual and Warranty & Maintenance booklet .
- Use only a high quality engine oi l that ex-
pressly complies with the Au di oil quality
standard specified for your vehicle's engine.
Using any o ther oil can cause serious engine
damage.
- Do not mix any lubricants o r other additives
into the engine oil. Doing so can cause en­
gine damage.
@ Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
your eng ine requ ires, you may add a total of
no more than 0 .5 qt (0.5 l) of a h igh-quali ty
"synthet ic"oil that meets the following speci ­
fications.
- Applies to: gaso line engine: ACEA A3 or
API SM with a viscosity grade of SAE OW-30,
SAE 5W-30 or SAE 5W-40.
- Applies to: diesel engine: ACEA C3 or API CF
with a viscosity grade of SAE OW-30 o r
SAE 5W-30 .
- For more information about engine oil that
has been approved for your vehicle, please
contact e ither your authori zed Audi dea ler
or Audi Customer Relat ions at
1 (800) 822-2834 or visit our web site at
www .audiusa .com or www .aud ica nada.ca.
Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all of
its moving parts .
In order to provide effective lub rication and cool­
ing of in ternal engine componen ts, all internal
Ch eck ing and Filling
combustion engines consume a certain amo unt
of oil. Oil consumption vari es from engin e to en­
gine and may change s ignificantly over the life of
the engine . Typ ically, engines w ith a specified
break-in period (see¢
page 65) consume mo re
o il during the break -in per iod than they consume
after o il consumption has stab il ized .
Under normal cond itions, the rate of oil con ­
sump tion depends on the qu ality and viscos ity of
the oil, the RPM (revolutions per minute) at
wh ich the engine is operated, the amb ient tem­
perature and road co ndit ions. Further facto rs a re
the amount of oi l di lution from wate r condensa ­
tion or fuel resid ue and the oxidat ion level of the
o il. As any engine is subject to wear as mileage
builds up, the oil consumption may increase over
time unti l replac ement of worn components may
become necessary.
With a ll these variab les coming into play, no
standard rate of oil consumption can be estab ­
li sh ed or sp ecified . There is no alternative to reg­
u lar and frequent checking of the oi l level, see
Note .
If the yellow engine oil leve l warning symbo l in
the instr ument cluster
Ill lights up, yo u should
check the oi l level as soon as possible
¢
page 204. Top off the o il at your earliest con­
venience ¢
page 204 .
A WARNING
-Before you check anyt hing in the engine com -
partment, always read and heed all WARN­
INGS
¢ .&. in Working in the engine compart­
ment on page 199.
{(D Note
Driving w it h an insufficient oil level is likely to
cause severe damage to the eng ine .
(D Tips
-The oil pressure wa rn ing display. is not
an indicator of the o il leve l. Do not rely on
i t . Instead, check th e oil level in your en­
gine at regular interval s, preferably each
time you refuel, and alway s before going
on a long trip .

system
ill General notes
Each tire, including the spare (if provided),
shou ld be checked monthly whe n cold and inflat­
ed to the i nflat io n press ure recommended by the
vehicle manufacturer on the veh icle placard or
t ir e inflation pressure labe l. (If your ve hicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
bel, you should determ ine the proper tire infla­
t ion pressure for those tires).
As an added safety feature, yo ur vehicle has been
equipped with a tire pressure mon itor ing system
(TPMS) that illuminates a low tire pressure tell­
ta le when one or more of your tires is signif icant­
ly under-inflated. According ly, when the low t ire
pressure te lltale illum inates, you sho uld stop and
chec k your tires as soon as possib le, and inflate
t h em to the prope r pressure. Dr iving on a sig nifi­
ca nt ly unde r-inflated t ire causes the t ire to over ­
hea t and can lead to tire fa il ur e. Under-inflat ion
also reduces fue l effic iency and tire tread life,
and may affect the vehicle's handling and stop -
ping ability .
