Anchorages provide a secure and easy-to-use at­
tachment and m inimize the possibility of improp ­
er child restraint installation.
All child restraints manufactured after Septem­
ber 1, 2002, must have lower anchorage attach-
ments for the

Tether anchors and tether straps
Fig. 147 Tether anchors: recess flaps behind the rear seat­
ba cks
The tether anchors for the rear seating positions
are located in recesses in the rear window shelf
~fig. 147
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 reduce the for­ ward movement of the child restraint in a crash,
in order to help reduce the risk of head injury that
could be caused by striking the vehicle interior.
Forward 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.
&_ 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 restraint you
intend to install in your Audi.
- Improper use of child restraint anchors (in­
cluding tether anchors) can lead to injury in
a collision. The anchors are designed to
withstand only those loads imposed by cor ­
rectly fitted child restraints .
- 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.
188
.
- 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 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
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.

Checking and Filling
"' Check the oil level again after two minutes
¢ page 203 , Checking the engine oil level.
"'Add oil, if necessary.
"'Close the engine oil filler cap and push the dip­
stick all the way in.
A WARNING
- When adding oil, do not let oil drip onto hot
engine components. There could be risk of a
fire.
- You must secure the cap on the oil filler
opening correctly so that oil does not leak
out onto the hot engine and exhaust system
when the engine is running, because this is
a fire hazard.
- Always clean skin thoroughly if it comes into
contact with engine oil.
(D Note
- Applies to vehicles with gasoline engines:
the oil level cannot be above the
0 range
¢ page 203, fig. 159, because this can
cause damage to the catalytic converter or
the engine. Contact an authorized Audi
dealer or authorized Audi Service Facility to
have excess oil extracted if necessary.
- Applies to vehicles with diesel engines: the
oil level must not be in the
(v range
¢ page 203, fig. 160 -The oil must not be
extracted, because this can damage the en­
gine. Drive to an authorized Audi dealer or
authorized Audi Service Facility immediate­ ly .
- Do not mix any additional lubricants into
the engine oil. Damage cause by such addi­
tives is not covered by the warranty.
@ For the sake of the environment
- Oil should never enter the sewer system or
come into contact with the ground.
- Pay attention to legal requirements when
disposing of empty oil containers .

· Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta­ tion.
Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS
¢ page 198.
The engine oil must be changed according to the
intervals specified in your Warranty & Mainte­
nance booklet . This is very important because the
lubricating properties of oil diminish gradually
during normal vehicle use.
Under some circumstances the engine oil should
be changed more frequently. Change oil more of ­
ten if you drive mostly short distances, operate
the vehicle in dusty areas or under predominantly stop-and-go traffic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oil will make fresh oil
look dark after the engine has been running for a
short time. This is normal and is not a reason to
change the oil more often than recommended.
Because of the problem of proper disposal, along
with the special tools and necessary expertise re­
quired, we strongly recommend that you have
your oil changed by an authorized
Audi dealer or
a qualified service station.
If you choose to change your oil yourself , please
note the following important information:
A WARNING
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
-
- To reduce the risk of burns from hot engine
oil, let the engine cool down to the touch.
- When removing the oil drain plug with your
fingers, stay as far away as possible. Always
keep your forearm parallel to the ground to
help prevent hot oil from running down your
arm.

Adding coolant
Fig. 162 Eng ine compartment: ma rkings on the coola nt
expans ion tank

checking anything in the engine compartment
r::;,page 198.
Checking the engine coolant level
.. Park your vehicle on a level surface.
.. switch the ignition off.
.. Read the coolant level on the coolant expansion
tank
r::;, fig . 162 . The coolant level must be be ­
tween the mark ings when the engine in cold .
When the engine is warm it can be slightly
above the upper marking .
Adding coolant
Requirement: there must be a residual amount of
coolant in the expans ion tank
c> Q).
.. Let the engine cool down.
.. Place a cloth over the coolant expansion tank
cap and unscrew the cap counterclockwise
<=>& .
.,. Add coolant mixed in the correct ratio
r::;, page 205 up to the upper marking .
.. Make sure that the fluid level rema ins stable.
Add more coolant if necessary.
.. Close the cap secure ly.
A coolant loss s uggests a leak. Immediate ly drive
your veh icle to an authorized A udi dealer or au­
thor ized Audi Service Facility and have the cool­
ing system inspected.
If the cooling system is not
leaking, a loss can come from the coolant boiling
206
thro ugh ove rheating and being pushed out o f the
cooling system.
A WARNING
The cooling system is pressurized and can be­
come very hot. To reduce the risk of burns
from hot coolant:
- Do not open the coolant expansion tank cap
w ith the engine hot. There is a risk of burns .
- Stop the eng ine and a llow it to cool.
- Protect your face, hands and arms from es-
caping coolant and steam by covering the
coo lant tank cap with a large, thick cloth.
- Turn the coolant tank cap counterclockwise
slowly and keep light pressure on the cap.
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto the e x­
haust system or hot engine components.
The ethy lene glycol in engine coola nt can
catch fire under certa in circumstances.
- The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the o riginal container
away from ch ildren . The re is a risk of poison­
ing .
- W hen working in the engine compartment,
remember that the rad iator fa n can switch
on ev en if the ignition is switched off, wh ich
increases the risk of pe rsonal injury.
@ Note
Do not add coolant if the expans ion tank is
empty . Air cou ld enter the cooling system and
damage the eng ine. If this is the case, do not
continue driving. See an author ized Audi deal ­
er or a uth ori zed Audi Service Facility for a ssis­
ta nce .
