A 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 following special
precautions 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
tions provided with the child 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 seat's fore and aft
adjustment range, as far away from the air­ bag as possible, before installing the for­
ward-facing child restraint.
-Always make sure that the safety belt upper anchorage is behind the child restraint and
not next to or in front of the child restraint
so that the safety belt will be properly posi­
tioned.
- 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.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the time
whenever the ignition is switched on.
- If the light does not stay on, perform the
checks
c:> page 2 3 7, Monitoring the Ad­
vanced Airbag System.
Child safety
- Take the child restraint off the front passen­
ger seat and install it properly at one of the
rear seat positions if the
PASSENGER AIR
BAG OFF
light does not stay on whenever
the ignition is switched on.
Booster seats and safety belts
Properly used booster seats can help protect
children weighing between about 40 lbs. and 80
lbs . (18 kg and 36 kg) who are less than 4
ft . 9
in . (57 inches/1 .45 meters) tall.
Fig. 243 Rear seat: c hild properly restrain ed in a boos ter
seat
The vehicle 's safety belts alone will not fit most
children until they are at least 4 ft . 9 in. (57 in­
ches/1.45 meters) tall and weigh about 80 lbs.
(36 kg). Booster seats raise these children up so
that the safety belt will pass properly over the
stronger parts of their bodies and the safety belt
can help protect them in a crash.
" Do not use the convertible locking retractor
when using the vehicle's safety belt to restrain
a child on a booster seat.
"The shoulder belt must lie as close to the cen­
ter of the child's collar bone as possible and
must lie flat and snug on the upper body. It
must never lie across the throat or neck. The
lap belt must lie across the pelvis and never
across the stomach or abdomen. Make sure the
belt lies flat and snug . Pull on the belt to tight­
en if necessary.
"If you must transport an older child in a boos­
ter seat on the front passenger seat, you can
use the safety belt height adjustment to help
adjust the shoulder portion properly.

Gasoline additives
Applies to: vehicles with gasoline engine
A majo r concern among many auto manufactur ­
ers is carbon deposit build-up caused by the type
of gasoline you use.
A lthough gasoline grades d iffer from one manu­
facturer to another, they have cer tain things in
common . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves . A l­
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website (www .toptiergas .com) .
Check ing and F illing
A fter an extended period of using inadequate
fuels, carbon deposit bui ld-ups can rob your en ­
gine of peak performance.
