vide supplemental protection in certain frontal
collisions.
.,&. WARNING
Not using a booster seat, using the booster
seat improperly, incorrectly installing a boos­
ter seat or using the vehicle safety belt im­
properly increases the risk of serious personal
injury and death in a collision or other emer­
gency situation. To help reduce the risk of se­
rious personal injury and/or death:
- The shoulder belt must lie as close to the
center 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 that the belt lies flat and snug.
Pull on the belt to tighten if necessary.
- Failure to properly route safety belts over a
child's body will cause severe injuries in an
accident or other emergency situation
¢ page 139.
-The rear side of the child safety seat should
be positioned as close as possible to the
backrest on the vehicle seat .
- For adjustable head restraints: adjust or re­
move the rear seat head restraint if it is dif­
ficult to install the child seat with the head
restraint in place
¢ page 52. Install the
head restraint again immediately once the
child seat is removed. Driving without head
restraints or with head restraints that are
not properly adjusted increases the risk of
serious or fatal neck injury dramatically.
- Never let a child put the shoulder belt under
the arm or behind the back, because it could
cause severe injuries in a crash.
- Children on the front seat of any car, even
with Advanced Airbags, can be seriously in­
jured or even killed when an airbag inflates .
- Never let a child stand or kneel on any seat,
for example the front seat.
- Never let a child ride in the cargo area of
your vehicle.
182
- Always remember that a child leaning for­
ward, sitting sideways or out of position in
any way during an accident can be struck by
a deploying airbag . This will result in serious
personal injury or death .
- If you must install a booster seat on the
front passenger seat because of exceptional
circumstances the
PASSENGER AIR BAG
OFF
light must come on and stay on, when­
ever the ignition is switched on.
- If the
PASSENGER AIR BAG OFF light does
not come on and stay on, perform the
checks described ¢
page 159, Monitoring
the Advanced Airbag System .
-Take the child restraint off the front passen­
ger seat and install it properly at one of the
rear seat positions if the

Securing child seats
Securing a child safety seat using a safety
belt
Safety belts for the rear seats and the front pas­
senger con be locked with the convertible locking
retractor to properly secure child safety seats.
The safety belts emergency locking retractors for
the rear seats safety belts and for the front pas­
senger's seat safety belt have a convertible lock­
ing retractor for child restraints. The safety belt
must be locked so that belt webbing cannot un­
reel. The retractor can be activated to lock the
safety belt and prevent the safety belt webbing
from loosening up during normal driving . A child
safety seat can only be properly installed when
the safety belt is locked so that the child and
child safety seat will stay in place.
Always remember : Even though your vehicle is
equipped with an Advanced Airbag system, all
children, especially those 12 years and younger, .,.

cle is moving .
- Do not continue to operate your vehicle un­
der these cond itions, as otherwise fuel can
reach the catalytic converter . This could re­
su lt in overheating of the converter, requ ir­
i ng its replacement .
- To assure efficient operation of the Emis­
sion Control System :
- Have your ve hicle main tained pro perly and
in accordance with the service recommen ­
dations in your Wa rranty & Maintenance
book let.

proper use of the vehicle will impair the
function of the emission cont rol system
and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is op­
erat ing properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erat ing states . This depends on the su lfur
content of the fuel be ing used . Using a differ­
ent brand of fue l may he lp, or filling the tan k

- The engine oil consumption may be up to
0.5 quart/600 miles (0.5 liter/1 ,000 km),
depending on driving style and operating
conditions . Consumption may be higher
during the first 3,000 miles (5,000 km). Be­
cause of this, the engine oil level must be
checked regularly .
It would be best to check
each time you refuel your vehicle and before
long drives .
Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta­
tion.
Before you check anything in the engine compart ­
ment ,
always read and heed all WARNINGS q .&.
in Working in the engine compartment on
page 198.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
nance booklet. This is very important because the
lubricating properties of oil diminish gradually
during normal vehicle use.
Under some circumstances the engine oil should
be changed more frequently . Change oil more of­
ten if you drive mostly short distances , operate
the vehicle in dusty areas or under predominantly
stop-and-go traffic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oil will make fresh oil
look dark after the engine has been running for a
short time. This is normal and is not a reason to
chang e the oil more often than recommended.
Because of the problem of proper disposal, along
with the special tools and necessary expertise re­
quired, we strongly recommend that you have
your oil changed by an authorized
Audi dealer or
a qualified service station .
If you choose to change your oil yourself, please
note the following important information:
204
A WARNING
-
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot engine
-
oil, let the engine cool down to the touch .
- When removing the oil drain plug with your
fingers, stay as far away as possible. Always keep your forearm parallel to the ground to
help prevent hot oil from running down your
arm .
- Drain the oil into a container designed for
this purpose, one large enough to hold at
least the total amount of oil in your engine.
- Engine oil is poisonous . Keep it well out of
the reach of children.
- Continuous contact with used engine oil is
harmful to your skin . Always protect your
skin by washing oil off thoroughly with soap
and water.
(D Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adversely affect your Audi Limited New Vehi­
cle Warranty.
@ For the sake of the environment
- Before changing your oil, first make sure you know where you can properly dispose of
the used oil.
- Always dispose of used engine oil properly .
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle used engine oil by taking it to a used
engine oil collection facility in your area, or
contact a service station .
Cooling system
Coolant
The engine cooling system is filled with a mixture
of purified water and coolant additive at the fac-
tory. This coolant must not be not changed. ..,.

Checking and Filling
_& WARNING
-The cooling system is under pressure. Do
not open the coolant expansion tank cap
when the engine is hot. This increases the
risk of burns.
- The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning .
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
CD Note
Do not add coolant if the expansion tank is
empty. Air could enter the cooling system and
damage the engine. If this is the case, do not
continue driving. See an authorized Audi deal­
er or authorized Audi Service Facility for assis­
tance .
