¢ fig. 166.
The a irbag on the passenger side makes the front
seat a potentia lly dangerous p lace for a child to
ride . The front seat is not the safest place for a
child in a forward-facing chi ld seat. It is a very
dangerous place for an infant or a larger child in
a rearward-facing seat .
A WARNING
Not using a child safety seat, using the wrong
child safety seat or improperly installing a
child restra int increases the r isk of serious
personal injury and death in a crash .
- Never install rear -facing child safety seats
or infant carriers on the front passenger
seat -even with an Advanced Airbag System.
A ch ild will be seriously injured and can be
killed when the inflating airbag hits the
child safety seat or infant carrier with great
force and smashes the child safety seat and
child against the backrest, center armrest
'
door or roof c> page 149, Child restraints on
the front seat -some important things to
know .
-Always install rear-facing child safety seats
or infant carriers on the rear seat.
- Never install a rear-facing child restraint in the forward-facing direction. Such restraints
are designed for the spec ial needs of infants
and very small children and cannot protect
them properly if the seat is forward-facing .
- If you must install a rearward facing ch ild
safety seat on the front passenger seat be­
cause of exceptiona l circumstances and the
PAS SENGER AIR BAG OFF light does not
come on and stay on, immed iate ly install
the rear-facing child safety seat in a rear
seating position and have the airbag system
inspected by your Audi dealer .
- Never place or use any electrical device (such as a laptop, CD player, electronic
games dev ice, power inverter or seat heater
for child seats) on the front passenger seat
if the device is connected to the 12-volt
socket or the cigarette lighter socket .
Child safety
-If a seat heater has been retrofitted or oth­
erwise added to the front passenger seat,
never install any child restra int system on
this seat .
- Make sure that there are no wet objects
(such as a wet towel) and no water or other
liquids on the front passenger seat cush ion.
- Never place objects on the seat (such as a
laptop, CD p layer, electronic games device,
power inverter o r seat heater for ch ild
seats) . These may influence the electrical
capacitance measu red by the capacitive pas­
senger detect ion system and can also fly
aro und in an accident and cause serious per­
sonal injury .

&_ WARNING
If exceptional circumstances require the use
of a forward-facing child restraint on the
front passenger's seat, the child's safety and
well-being require that the follow ing spec ial
precaut ions be taken:
- Make sure the forward-facing seat has been
designed and certified by its manufacturer
for use on a front seat with a passenger
front and side airbag .
-Always follow the manufacturer 's instruc­
t ions prov ided with the ch ild safety seat or
infant carrier.
- Always move the front passenger seat to
the highest position in the up and down ad­
justment range and move it back to the
rearmost position in the se at's fore and aft
adjustment range, as far away from the air­
bag as possib le, before insta lling the for ­
ward-facing child restra int .
- Always make sure that the safety belt upper
anchorage is behind the child restraint and
not next to or in front of the chi ld restraint
so that the safety belt will be properly pos i­
t ioned.
- Always make sure that nothing prevents the
front passenger's seat from being moved to
the rearmost position in its fore and aft ad­
justment range.
- Always make sure the backrest is in an up­
right position.
Ch ild safety
-Never p lace or use any e lectrica l device
(such as a laptop, CD player, e lectron ic
games device, power inverter or seat heater
for child seats) on the front passenger seat if the device is connected to the 12-volt
socket or the cigarette lighte r socket.
- If a seat heater has been retrofitted or oth­
erwise added to the front passe nger seat,
never install any child restra int system on
this seat.
- Make sure that the re are no wet objects
(such as a wet towel) and no wate r o r other
liqui ds on t he front passenger seat cush ion.
- Never p lace objects on the seat (such as a
laptop, C D playe r, electro nic games device,
power inverter o r seat heater fo r ch ild
seats). These may influence the electri cal
capacitance measu red by the capacitive pas­
senger detect ion system and can also fly
aro und in an accident and cause serious per­
sonal injury.
- Make sure that the

Child safety
-Always make sure the seat backrest to which
the child restraint is installed is in an up­
right position and securely latched into
place and cannot fold forward. Otherwise,
the seatback with the child safety seat at­
tached to it could fly forward in the event of
an accident or other emergency situation.

Deactivating the convertible locking
retractor
The convertible Locking retractor for child re­
straints will be deactivated automatically when
the belt is wound all the way bock into the re­
tractor .
~ Press the red button on the safety belt buckle .
Th@ belt tongue will pop out of the buckle.
~ Guide the safety belt all the way back into its
stowed position .
Always let the safety belt retract completely into
its stowed position . The safety belt can now be
used as an ordinary safety belt without the con­
vertible locking retractor for child restraints .
If the convertible locking retractor should be ac­
tivated inadvertently, the safety belt must be un­
fastened and guided completely back into its
stowed position to deactivate this feature. If the
convertible lock ing retractor is not deactivated,
the safety belt will gradually become tighter and
uncomfortable to wear.
A WARNING
-
Improperly installed child safety seats in­
crease the risk of serious personal injury and
death in a collision.
- Never unfasten the safety belt to deactivate
the convertible locking retractor for child re­ straints while the vehicle is moving . You

LATCH system (lower
anchorages and tethers
for children)
' Child Restraint System anchors and how
are they related to child safety
To provide a simpler and more practicable way to
attach the child restraint on the vehicle seat, Federal regulations require special lower ancho­
rages in vehicles and devices on new child re­
straints to attach to the vehicle anchorages .
In the United States, the combination of the
tether anchorages and the lower anchorages is
now generally called the LATCH system for
"Lower Anchorages and Tethers for Children" . In
Canada, the terms "top tether" with "lower uni­
versal anchorages" (or "lower universal anchor­
age bars") are used to describe the system .
In other countries the term "ISOFIX" is used to
describe the lower anchorages .
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 seats.
Installing a child restraint that requires a top
tether without one can seriously impair the per­
formance of the child restraint and its ab ility to
protect the child in a collision. Installing a child
restraint that requires a top tether without the
top tether may be a violation of state law.
Child restraint manufacturers offer LATCH lower
anchorages on their child seats with hook-on or ...

Catalytic converter
Applies to: vehicles with gasoline engine
It is very important that your emission control
system (catalytic converter) is func tioning prop­
erly to ensure that your vehicle is running in an
environmentally sound manner .
~ Always use lead-free gasoline c> page 191, Fuel
supply .
~ Never run the tank down all the way to empty.
~ Never put too much motor o il in your engine
c> page 204, Adding engine oil.
~ Never try to push- o r tow-start your vehicle .
The catalytic converter is an efficient "clean -up "
device built into the exhaust system of the veh i­
cle. The catalyt ic converter b urns many of the
po llutants in the exhaust g as befo re they are re­
l eased into the atmosphere.
The exclusive use of un leaded fuel is critically im­
po rtant fo r the life of the catalytic converte r and
prope r funct io ni ng of the engine.
_&. WARNING
The temperat ure of the exhaus t sys tem is
high, both when driv ing and a fter stopping
the engine.
-
- Never tou ch the exhaust tail pipes once they
have become hot. This cou ld resu lt in burns.
- D o not p ark or operate the vehicle in ar eas
where the hot exhaust system may come in
contact with dry g rass, brush, fuel spi ll or
other mate rial which can ca use a fire.
- Do not apply additiona l undercoating or
rustp roofing on or near the exhaust mani­
fold, exha ust pipes, cata lytic conve rter or
heat shields . D uring driving, the substance
used for unde rcoat ing could overheat and
cause a fire .

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
150 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
Gross A xle Weight Rating
("GAWR") is the maximum load
that can be appl ied at each of the
vehicle's two axles.
The fact that there is an upper
limit to your vehicle's Gross Vehi ­
c le Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a tra iler 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.

_& WAR NING
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal in jury, 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 Vehicle 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)
¢ page 221, fig. 192.
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
¢ page 221 , fig. 192 .
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
226
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
(¢ page 211, fig. 190) to deter­
mine the designated load rating
for a specific tire.

(D Note
Vehicles with an automat ic transmission can­
not be started by pushi ng or towing.
Starting with jumper
cables
If necessary, the engine con be started by con­
necting it to the battery of another vehicle .
If the engine should fail to start because of a dis ­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumper cables to start the engine.
Jumper cables
Use only jumper cables of suffic iently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use on ly jumper cables with
insulated term inal
clamps which are distinct ly marked :
plus(+ ) cable in most cases co lored red
minus (-) cable
in most cases colored black .
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal in­
jury. Follow the instructions below for safe hand Ling of your veh icle's batte ry .
- Always shield your eyes and avo id leaning
over the battery whenever possible.
- A dead battery can freeze at temperatures
around 32 °F (0 °C). If the vehicle battery is
frozen, you must thaw it before connecting
the jump start cables.
If you do not, this in-
254
creases the risk of an explosion and chemi­
cal burns. After jump starting the vehicle,
drive to an authorized Audi dealer or author­
ized Audi Service Fac ility immediately to
have the vehicle battery checked.
- Do not allow battery acid to contact eyes or
skin . Flush any contacted area with water
immed iately.
- Improper use of a booster battery to start a
veh icle may cause an explosion .
- Vehicle batteries generate explosive gases.
Keep sparks, flame and lighted cigarettes
away from batter ies .
- Do not try to jump start any vehicle with a
low acid level in the battery .
- The voltage of the booster battery must also
have a 12-volt rat ing. The capacity (Ah) of
the booster battery should not be lower
than that of the discharged battery. Use of
batter ies of different voltage or substantial­
ly different "Ah" rating may cause an exp lo­
sion and persona l injury.
- Never cha rge a frozen battery. Gas trapped
in the ice may cause an explosion.
- Never cha rge o r use a battery that has been
frozen . The battery case may have be weak­
ened.
- Use of batter ies of different voltage or sub­
stantially diff erent capacity (Ah) rating may
cause an explosion and injury . The capacity
(Ah) of the booster battery should not be
lower than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
