Child safety
• Pull straps tight following the child restraint
manufacturer's instructions.
Releasing
• Loosen the tension on the straps following the
child restraint manufacturer's instructions.
• Depress the spring catches to release the an­
chorage hooks from the lower anchorages.
Remember: Use tether straps to help keep the
child restraint firmly in place.
8_ WARNING
Improper use of the LATCH system can in­
crease the risk of serious personal injury and
death in an accident.
- These anchors were developed only for child
safety seats using the "LATCH" system.
- Never attach other child safety seats, belts or other objects to these anchors.
- Always make sure that you hear a click when
latching the seat in place. If you do not hear
a click the seat is not secure and could fly
forward and hit the interior of the vehicle,
or be ejected from the vehicle.
8_ WARNING
Improper installation of child restraints will
increase the risk of injury in an accident.
- Always follow the child restraint system manufacturer's instructions for proper in­
stallation of the child restraint system and
proper use of tether straps as well as the
lower anchorages or safety belts in your ve­
hicle.

Tether anchors and tether straps
Fig. 151 Tether an ch ors : recess flaps beh in d th e rear seat­
backs
The tether anchors for the rear seating positions
are located in recesses in the rear window shelf
¢fig. 151.
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 child head move­
ment performance requirements. These new per­
formance requirements make a tether necessary
on most new child safety seats.
8_ 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 .

-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 l uggage or other
items to the LATCH 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 we ight-sensing mat to measure
more we ight than is actually on the seat .
- The heav ier weight reg istered ca n make the
Advanced Airbag System work as though an
adult were on the seat and deploy the Ad­
vanced Airbag whe n it must be supp ressed
ca using se rious or even fatal injur y to the
c h ild.
- If you mu st install a rearwar d faci ng chi ld
sa fety seat on the front passenge r seat be­
cause of exceptional c ircums tances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immediate ly install
the rear-fac ing c hild safety seat in a rear
seating pos ition and have the airbag system
inspected by you r authorized Audi dea ler.

Cur rently, few rea rward-faci ng chi ld restraint sys­
tems come wit h a teth er. Please read and heed
the ch ild restraint system manufacturer's ins truc­

properly diagnosed. Keep in mind that the
accurate meas urement of oil cons umption
requires great care and may take some time.
An authorized Audi dealer has instructions
about how to measure oil consumption ac­
curately.
Checking the engine oil level
Fig. 162 MMI Disp lay: Oil level indicator
Read oil level

r:::>fig. 162. Add engine o il if the bar of the oil
level indicator is near "min"
r:::>page 195
Depending on the way the vehicle is driven and
the operating conditions, oil consumpt ion can be
up to a 1/2 quart per 600 miles (O.S liter per
1,000 km) . Consumption may be higher within
the first 3,000 miles (S,000 km).
@ Tips
The oil level indicator in the MMI* Display is
only an information disp lay. If the oil level is
too low, a minimum oil warn ing appears in
the instrument cluster. Add oil¢
