Child safety
Tether anchors and tether straps
Fig. 172 Tether anchors: recess flaps behind the rear seat·
backs
The tether anchors fo r the rear seating positions
are located in recesses in the rear window shelf
~ fig. 172
A tether is a stra ight or V-shaped strap tha t at­
taches the top part of a child restra int to speci al
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 help red uce the risk of head injury
that could be caused by strik ing the vehicle inte­
rior.
Forward fac ing 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 perfo rmance requirements make a tethe r
necessary on most new child safety seats.
A WARNING
Improper installation of ch ild restraints will
increase the r isk 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 Audi .
- Improper use of child restra int anchors (in­
clud ing tether anchors) can lead to inj ury in
a collision . The ancho rs are designed to
withs tand only those loads imposed by cor­
rectly fitted child restra ints.
- Never mount two chi ld restraint systems on
one LATCH lower a nchor po int.
188
- 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 be lts or other kinds of occu­
pant restraints.
- Never secure or attach any luggage or othe r
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
PASSEN GER 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 ai rbag system
inspected by yo ur Audi dea ler.

Checking and Filling
& WARNING
AdBlue can irritate the skin, eyes and respira­tory system. If there is contact with the fluid,
flush immediately with plenty of water . Con­
sult a physician if necessary.
(D Note
- Only use Ad Blue that conforms to the
standard ISO 22241 -1. Do not mix any addi ­
tives with the Ad Blue and do not dilute it
with water.
- Do not add Ad Blue to the diesel tank or add diesel fuel to the Ad Blue tank. Do not start
the engine under any circumstances if the
wrong fuel is filled in the tank. There is a
risk of damaging the fuel tank system and
the engine. See an authorized Audi dealer or
authorized Audi Service Facility for assis­
tance.
- AdBlue attacks surfaces such as painted ve­
hicle components, plastic and carpet. Re­
move the fluid as quickly as possible with a
damp cloth and plenty of cold water. If the
Ad Blue has already crystallized, use warm
water and a sponge . AdBlue residue that is
not removed will crystallize and can damage
the affected surface.
- Do not store refill bottles or canisters per ­
manently in the vehicle. If the container
leaks, the escaping AdBlue could damage
the vehicle interior.
- Do not allow AdBlue to come into contact
with clothing. If there is contact with the
fluid , flush immediately with plenty of
wa­
ter.

Emergency assistance
-If the spare tire has to be installed in the incor ­
rect direction, use the spare tire only tempora­
rily since the tire w ill not be able to achieve its
optimum performance characteristics with re­
gard to aquaplaning, noise and wear.
- We recommend that you pay particular atten­
tion to this fact during wet weather and that
you adjust your speed to match road condi­
tions.
- Replace the flat tire with a new one and have it
installed on your vehicle as soon as possible to
restore the handling advantages of a unidirec­
tional tire .
Notes on wheel changing
Please read the informat ion ~ page 217, New
tires or wheels
if you are going to use a spare tire
which is different from the tires on your vehicle.
After you change a tire:
-Check the tire pressure on the spare tire im­
mediately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos­
sible by your authorized Audi dealer or a
qualified service station .
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of 90
ft lb
(120 Nm) .
- If you notice that the wheel bolts are corroded
and difficult to turn while changing a tire,
they should be replaced before you check the
tightening torque.
- Replace the flat tire with a new one and have
it installed on your vehicle as soon as possi­
ble. Remount the wheel cover.
Until then, drive with extra care and at reduced
