Child safety
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.
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 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 luggage 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 weight-sensing mat to measure
more weight than is actually on the seat.
- The heavier weight registered can make the Advanced Airbag System work as though an
adult were on the seat and deploy the Ad­
vanced Airbag when it must be suppressed
caus ing serious or even fatal injury to the
child .
- 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
150
seating position and have the airbag system
inspected by your Audi dealer.

Installing the tether strap
.,. Release or deploy the tether strap on the child
restraint according to the chi ld restraint manu­
facturer's instructions.
.,. Guide the upper tether strap
under the rear
head restraint and into the rear cargo area
r:::;, fig. 131 (raise the head restraint if necessa­
ry). For child restraints with V-tether straps, al­
ways make sure that the head restraint guide
rods do not interfere with any part of the top
tether strap.
.,. Slide the tether strap hook over the anchor
bracket.
.,. Pull on the tether strap hook so that the spring
catch of the hook engages .
.,. Tighten the tether strap f irmly following the
child restraint manufacturer's instructions.
Releasing the tether strap
.,. Loosen the tension following the child restraint
manufacturer's instructions.

~ Depress the spring catch on the hook and re­
lease it from the anchorage.
@ Note
If you leave the ch ild 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
Current ly, few rear-facing chi ld 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 w ill be
ser iously injured and can be killed if the front
airbag inflates -even w ith an Advanced Ai rbag
System.
- T he 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.
- A tight tether or other strap on a rearward­
f acing child restraint attached to the front
passenger seat can put too much pressure
on the weight-mat in the seat and register a
heavier weight in the Advanced Airbag Sys­
tem. The heav ier weight registered can
make the system work as though an adult
were on the seat and deploy the Advanced
Airbag when it must be supp ressed causing
serious or even fatal injury to the child.
-If you must install a rearward facing ch ild
safety seat on the front passenger seat be­
caus e of exceptiona l circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immed iate ly install
Child safety
the rear-facing child safety seat in a rear
seating position and have the airbag system
inspected by your Audi dealer.

Audi recommends having all work
on tires or wheels performed by an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper
knowledge and are equipped with
the required tools and replace­ ment parts.
.,,. New tires do not yet have the
optimum gripp ing properties .
Drive carefully and at moderate
speeds for the first 350 miles (500 km) with new tires.
.,,. Only use tires with the same de­
sign, size (rolling circumference)
and as close to the same tread
pattern as possible on all four
wheels.
.,,. Do not replace tires individually .
At least replace both tires on the
same axle at the same time.

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop.
Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden

tire failure, including a blowout
and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­
sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat­
ing
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
11>

fuel, oil, coolant and other fluids plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of
1 50 lbs. (68 kg) for each passen­
ger at a designated seating posi ­
tion and the total weight of any
luggage in the vehicle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load.
The
Gr oss Axle Weight R ating
("GAWR") is the maximum load
that can be applied at each of the
veh icle's two axles.
The fact that there is an upper limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trai ler hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as
~ luggage.

Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
- Carrying more weight than
your vehicle was designed to carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
- Tires on a vehicle that has
been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
- Always make sure that the to­
tal load being transported -
including the weight of a trail­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle heavier than the vehicle's
Gross Veh icle Weight Rating .

Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas­
sengers and luggage or other
things that you plan to transport so that you can make sure that
your vehicle will not be overload­ ed .
Steps for Determining Correct
Load Limit
1 . Locate the statement "THE
COMBINED WEIGHT OF OCCU­ PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle 's placard
(tire inflation pre ssure label)
c:::> page 176, fig. 146.
2. Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle.
3 . Subtra ct the combined weight
of the driver and passengers
from
"XXX" kilograms or " XXX"
pounds shown on the sticker
c:::> page 176 , fig. 146 .
4. The re sulting figure equals the
available amount of cargo and luggage load capacity. For ex­
ample, if the
"XXX" amount
equals 1400 lbs. and there will
180
be five 150 lbs. passengers in
your vehicle, the amount of available cargo and luggage load capacity is 650 lb s.
(1400-750 (5 X 150) = 650
lb s.)
5. Determine the combined weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex­
ceed the available cargo and luggage load capacity calculat ­
ed in Step 4 .
6. If your vehicle will be towing a trailer, load from your trailer
will be transferred to your ve­
hicle. Con sult this manual to
determine how this reduces
the available cargo and lug­ gage load capacity of your vehi­
cle .
~check the tire sidewall
(c:::> page 167, fig. 144) to deter­
mine the designated load rating
for a specific tire.
