Fig. 163 Location of dr iver airbag: in steering whee l
Fig. 164 Location of front passenger's airbag: in the in­
strument panel
Your vehicle is equipped with an "Advanced Air­
bag System" in compliance with Un ited States
Federal Motor Vehicle Safety Standard
(FMVSS)
208, as well as Canada Motor Vehicle
Safety Standard (CMVSS)
208 as applicable at
the time your vehicle was manufactured. The
safety belts for the front seats have "pretension­
ers" that help to take slack out of the belt sys­
tem. The pretensioners are also activated by the
electronic control unit for the airbag system.
The front safety be lts also have load limiters to
help reduce the forces applied to the body in a
crash.
The airbag for the driver is in the steering wheel
hub<=>
fig . 163 and the airbag for the front pas­
senger is in the instrument panel
<=>fig. 164. The
general location of the airbags is marked "AIR­
BAG".

There is a lot you need to know about the airbags
in your vehicle . We urge you to read the detai led
i nformation about airbags, safety belts and ch ild
safety in this and the other chapters that make
up the owner's literature. Please be sure to heed
the WARNINGS -they are extremely important
for your safety and the safety of your passengers,
especially infants and small children .
.&_ WARNING -
Never rely on airbags alone for protection.
- Even when they deploy, airbags provide only
supp lemental protection.
- Airbag work most effectively when used
with properly worn safety belts .
- Therefore, always wear your safety belts and make sure that everybody in your vehicle is
properly restrained.
- Always hold the steering wheel w ith both
hands on the outside of the steering wheel
rim at the 9:00 o'clock and 3:00 o'clock po­
sitions to help reduce the risk of personal in­
jury if the driver's airbag inflates.
- Never hold the steering wheel at the
12
o'clock position or with your hands any­
where inside the steering wheel or on the
steering whee l hub. Holding the steering
wheel the wrong way increases the risk of
severe injury to the arms, hands, and head if
the driver airbag deploys.
.&_ WARNING
Objects between you and the airbag will in­
crease the r isk of injury in a crash by interfer­
ing with the way the airbag unfolds and/or by
being pushed into you as the airbag inflates.
- Always make sure nothing is in the front air-
bag deployment zone that could be struck
by the airbag when it inflates.
- Objects in the zo ne of a deploying airbag
can become projectiles when the airbag de­
ploys and cause serious personal injury.
- Never hold things in your hands or on your
lap when the vehicle is in use.
- Never place accessories or other objects (such as cup holders, telephone brackets,
note pads, navigation systems, or things
-

Convertible child safety seats
Properly used convertible child safety seats con
help protect toddlers and children over age one who weigh between 20 and 40 lbs (9 and 18 kg)
in a crash .

Fig. 1 72 Sche matic overv iew : installat ion of t he seat using
the vehicle's safety belt system
""When using the vehicle safety belt to install a
child safety seat, yo u must first act ivate the
convertib le locking retractor on the safety belt
t o prevent the chi ld safety seat from moving
¢ page 227.
"" Push the chi ld safety seat down with your full
weight to get the safety belt really tight so that
the seat cannot move forward or sideways
more than 1 in (2.S cm)¢
page 227.
A toddler or child is usua lly too large for an in­
fant restraint if it is more than one year old and
weighs more than 20 lbs (9 kg).
Toddlers and children who are older than one
year up to about 4 years old and weigh more than 20 lbs (9 kg) up to 40 lbs (18 kg) must always be
properly restrained in a child safety seat certified
for their size and we ight and ¢
fig. 172 .
A WARNING
Not using a child safety seat, using the wrong
chi ld safety seat or imprope rly installing a
chi ld restrain t inc reases the risk of ser ious
personal injury an d death in a co llision or oth­
e r emergency s ituation.
- Ch ild ren on t he front seat of a ny car, eve n
w it h Advanced Airbags, can be seriously in­
jured or even kill ed when an airbag inflates .
A child in a rearward-facing ch ild safety seat
installed on the front passenger seat will be .,.

Child safety
The vehicle's safety belts alone will not fit most
childr en until they are at least 4
ft 9 in (57 in/
1.45 m) tall and weigh about 80 lbs (36 kg) .
Booster seats raise these children up so that the
safety belt will pass properly over the s tronger
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 .
Children up to at least 8 years old (over 40 lbs or
18 kg) are best protected in child safety seats de­
signed for their age and weight. Experts say that
the skeletal structure, particularly the pelvis, of
these children is not fully developed, and they
must not use the vehicle safety belts without a
suitable child restraint.
It is usually best to put these children in appro­
priate booster seats. Be sure the booster seat
meets all applicable safety standards.
Booster seats raise the seating position of the
child and reposition both the lap and shoulder
parts of the safety belt so that they pass across
the child's body in the right places . The routing of
the belt over the child's body is very important
for the child's protection, whether or not a boos­
ter seat is used.
Never use the lap belt portion of the vehicle 's
safety belt alone to restrain any child, regardless
of how big the child is. Always remember that
children do not have the pronounced pelvic struc­
ture required for the proper function of lap belt
port ion of the vehicle's three point lap and
shoulder belts . The child's safety absolutely re­
quires that a lap belt portion of the safety belt be
fastened snugly and as low as possible around the pelvis. Never let the lap belt portion of the
226
safety belt pass over the child's stomach or abdo­
men.
In a crash, airbags must inflate w ithin a blink of
an eye and with considerable force. In order to do
its job, the airbag needs room to inflate so that it
will be there to protect the occupant as the occu­
pant moves forward into the airbag.
A vehicle occupant who is out of pos it ion and too
close to the airbag gets in the way of an inflating
airbag. When an occupant is too close, he or she
will be struck vio lently and w ill receive serious or
possibly even fatal injury.
In order for the airbag to offer protection, it is
important that all vehicle occupants , especially
any ch ildren, who must be in the front seat be­
cause of exceptional circumstances, be properly
restrained and as far away from the airbag as
possible. By keeping room between the child 's
body and the front of the passenger compart­
ment, the airbag can inflate completely and pro­
vide supplemental protection in certa in frontal
collisions.
,&. WARNING
Not using a booster seat, using the booster
seat improperly, incorrect ly installing a boos­
ter seat or using the vehicle safety belt im­
proper ly 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 . T he lap belt must lie across the pelvis
and never across the stomach or abdomen.
Ma ke sure that the be lt 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 189.
- The rear side of the chi ld safety seat should
be positioned as close as possible to the
backrest on the veh icle seat.

Checking and Filling
Audi dealer or authorized Audi Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and being pushed out of the cooling system.
A WARNING
The cooling system is pressurized and can be­
come very hot. To reduce the r isk of burns
from hot coolant:
- Do not open the coolant expansion tank cap when the eng ine is hot. This increases the
risk of burns.
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from es-
caping coolant and steam by covering the
coolant tank cap with a large, thick cloth.
- Turn the coolant tank cap counterclockwise
slowly and keep light pressure o n the cap.
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto the ex­ haust system or hot eng ine components .
T he ethylene glycol in eng ine coolant can
catch fire under certa in circumstances.
- The coo lant add itive and the coolant can be
dange rous to your health. For this reason,
keep the coolan t in the origina l container
and away from children. There is a risk of
poisoning.
- When working in the engine compartmen t,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of inj ury.
(D Note
Do not add coolant if the exp ansion 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.
