A WARNING
Chi ld ren on the front seat of any car even w ith
Advanced Airbags can be seriously injured or
even killed when an airbag inflates. A child in
a rearward-facing child safety seat installed
on the front passenger seat will be seriously
injured and can be killed if the front airbag in­
flates.
- The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the ch ild safety seat and child
against the backrest, center armrest, or
door.
- Always install rear-facing child safety seats
on the rear seat.
- If you must install a rearward fac ing ch ild
safety seat on the front passenger seat in
exceptiona l circumstances and the
PA SSEN ­
G ER AIR BAG OFF
light does not come on
and stay on, immediately insta ll the rear­
facing child safety seat in a rear seating po­
sition and have the airbag system inspected
immediately by your Audi dealer.
A WARNING
If, in exceptional circumstances, you must in­
stall a forward-facing chi ld restraint on the
front passenger's seat :
- Always make sure the forward-fac ing seat
has been designed and certified by its man­
ufacturer for use on a front seat with a pas­
senger front and s ide a irbag .
- Always follow the manufacturer's instruc­
tions prov ided with the ch ild safety seat or
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
rea rmost position in the seat's fore and aft
adjustment range, as fa r away from the air­
bag as possib le, before insta lling the for­
ward-facing child restraint .
- Always ma ke sure that the safety bel t 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 posi­
t ioned.
Ch ild safety
-Always make sure that the PA SSENGER AIR
BAG OFF
light comes on and stays on all the
time whenever the ignition is switched on.
@ Tips
A lways replace child restraints that were in­
stalled in a vehicle during a crash. Damage to
a child restraint that is not v is ible could cause
i t to fai l in another collision situat ion.
Advanced front airbag system and children
Your vehicle is equipped with a front "Advanced
Airbag System" in compliance with Un ited States
Federal Motor Vehicle Safety Standa rd (FMVSS)
208, as we ll as Canada Moto r Vehicle Safety
Standard (CMVSS) 208 as app licab le at the time
your vehicle was manufactured.
T he Advanced A irbag system in you r vehicle has
been certified to meet the "low- risk" require­
ments fo r 3- and 6-year old ch ildren on the pas­
senger side and sma ll adu lts on the driver side.
T he low risk deployment criter ia are intended to
reduce the risk of injury t hrough interaction with
the airbag that can occur, for example, by being
too close to the steering wheel and instrument
panel when the airbag inflates . In addition, the
system has been cert ified to comply with the
"supp ression" requirements of the Safety Stand­
ard, to turn off the front a irbag fo r infants up to
12 months who are restrained on the front pas­
senger seat in c hild rest raints t hat are lis ted in
the Standard.
E ven though your veh icle is eq uipped wit h an Ad­
vanced Airbag system, all ch ild ren, especially
those 12 yea rs and younger, should a lways ride
in the back seat proper ly restrained for their age
and size . The airbag on the passenger side makes
the front seat a potentially dangerous place for a
child to ride. The front seat is not the safest place
for a child in a forward-fac ing ch ild safety seat. It
can be a very dangerous place for an infant or a
larger ch ild in a rearward-facing seat .

Wheels and Tires
General information
1>-(heck your tires regularly for
damage (punctures , cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­ proach the curb at an angle.
1>-Have faulty tires or rims re­
placed immediately.
1>-Protect your tires from oil,
grease and fuel.
.,. Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
1>-Lay tires flat when storing and
store them in a cool , dry location
with as little exposure to light as possible.
_&. WARNING -
-Never drive faster than the
maximum permitted speed
for your tires . This could cause
the tires to heat up too much.
This increases the risk of an
accident because it can cause
the tire to burst .
-Always adapt your driving to the road and traffic condi-
166
tions. Dr ive carefully and re ­
duce your speed on icy or slip­
pery roads. Even winter tires
can lose traction on black ice .
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical
in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months . Low
temperatures significantly de­
crease the elasticity of summ­
er tires, which affects traction
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­
aged by road salt or similar
substances.

guarantee that a tire will last for
a prescribed number of miles (kilome ters) or perform in a cer­
tain way. It simply gives tire buy­
ers add it iona l information to
combine with other considera ­
