2008 AUDI TT ROADSTER airbag off

___ C_h_ i_ ld _ S_ a_ f_ e_ t_y ____________________________________________ _
Children up to about 40 lbs (18 kg) are best protected in child safety
seats designed for their age and weigh t. Experts say that t he skel ­
eta l structure, part icularly the pelv is, of these ch ildren is not fully
developed, and they s hou ld not use the vehicle sa fe ty be lts
::::>fig .140 .
Children who weigh more than 40 lbs . (1 8 kg) may generally use the
available three point combinat ion lap and shou lder belts when t hey
sit on an appropriate booster seat. Be sure the booster seat meets
all applicable safety sta ndards .
Booster seats raise the seating position of the ch ild and reposition
both the lap and s hou lder par ts of t he safety belt so tha t they pass
across the c hild's body in the right places. The routing o f the belt
over the child's body is very important for the child 's p rotection.
This app lies whenever a ch ild uses the vehicle's safety bel ts, even
when the child is big enough to use them without a booster seat.
In a crash, air bags must inflate with in a blink o f an eye and with
considerable force . In order to do its job, the airbag needs room to
inf late so tha t it wi ll b e there to pr otec t th e occ up ant as the occu ­
pant moves forward into the airbag .
A vehic le occupant including a child who is out of position and too
close to the airbag ge ts in the way of an inflati ng airbag. When an
occupant is too close , he or she will be struck vio lent ly and will
receive serious or p ossi bly eve n fatal injury.
In order for the airbag to offer protect ion , it is important that all
veh ic le occupan ts, especia lly any c hild ren, who mu st be in the fron t
seat in exceptional circumstances , be properly restrained and as far
away from the airbag as possible. By keeping room between the
child's or othe r occupant's body and the front of the passenger
compartment, the airbag can inflate fully and comp letely and
provid e supp lemental pro tec tion in cer tain fro ntal crashes.
& WARNING
Not using a booster seat , using the booster seat improperly , incor ­
rectly installing a booster seat or using the vehicle s afety belt
& WARNING (continued )
improperly in creases the r isk of serious personal injur y and death
in a collision or other emergency situation . To help reduce the risk
of ser ious p ersonal injury and /or death :
• Alway s make sure to position the shoulder portion of the three­
point belt over the middle of child's shoulder .
• Never let the shoulder portion of the belt rest against or acro ss
the neck , face , chin , or throat of the child .
• Always make sure the lap belt portion of the three -point belt is
worn snug and passes as low as possible across the child's pelvis .
Never let the belt pass o ver the soft abdomen.
• Failure to properly route safety belts over a child's body will
cause severe injuries in an accident or other emergency situation
=> page 137 .
• Children on the front seat of any car , even with 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 pa ssenger seat will be seriously injured and can be killed
if the front airb ag 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 .
• Alway s remembe r that a child leaning forward , sitting side­
ways or out of po sition in any way during an accident can be
s truc k by a deploy ing airb ag. This will result in serious personal
injury or death .
• If you must install a rearward facing child safety 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 swit ched on .

on whenever the ignition is switched on the inflating airbag will
hit the child safety seat or infant carrier with great force and will
smash the child safety seat and child against the backrest, door or
roof. Have the airbag system inspected immediately by your Audi
dealer.

Child Safety
& WARNING
Using wrong child restraints or improperly installed child
restraints can cause serious personal injury or death in a crash.
• Failure to properly route safety belts over a child's body will
cause severe injuries in a crash. The lap belt portion of the three
point belt must always pass as low as possible across the pelvis,
never over the stomach or abdomen.
• An improperly worn safety belt will not provide the best protec­
tion in a crash and may cause serious personal injury. Always
make sure that children and other vehicle occupants properly
wear available restraint systems. Carefully follow the instructions provided by the manufacturers of child restraints. •
Installing a child safety seat
Securing a child safety seat using a safety
belt
Safety belts for the front passenger can be locked with the
convertible locking retractor to properly secure child
safety seats.
The safety belts emergency locking retractors for the front
passenger's seat safety belt have a convertible locking retractor for
child restraints. The safety belt must be locked so that belt webbing
cannot unreel. 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, a child should always ride in the seat properly restrained for its age and size. .,_

get the safety belt really tight.
- Insert the belt tongue into the buckle for that seating
position .
- Guide the safety belt back into the retractor unt il the belt
lies flat and snug on the child safety seat.
- You should hear a "clicking" noise as the belt winds back
into the inertia reel. Test the convertible locking retractor
by pul ling on the belt. You should no longer be able to
pull the belt out of the retractor. The convertible locking
retractor is now activated .
- Make sure that the red release button is facing away from
the child restraint so that it can be unbuckled quickly.

Natural leather
Aud i m akes gre at effo rts to maint ain th e pr oper ties,
n atur al look and feel of interi or le ather.
Gener al
We offe r many d ifferent types of leathe r on our vehicles. Mo st are
different types of nappa leather , which has a smooth surface and
comes in various co lo rs.
The intensity o f the color determ ines the visua l characteristics and
appearance. If the surface of the leather has a typical natura l look,
then t he leather is a nappa lea ther that has bee n left in a re latively
natura l condition. This leather offers particu lar ly good comfort and
b reathes well. Fi ne veins, closed g ra ins, insect bites, skin folds, an d
subtle variations in co lor remain visib le. These characteristics
dem onstrate that the mater ial is natural.
Natura l nappa leather is not covered by a co lor finish . It is therefore
more sensitive to soil ing and wear, which is something you need to
consider if chi ldren, animals or other fac tors might prove to be
particularly hard on the leather.
By con trast, leather types that are covered by a colo red fin ish layer
are more durable. This has a positive effect on the leather's resis ­
tance to wea r and s oiling i n daily use . On the ot her hand, the typical
characteristics of natura l leather are barely or not apparent .
However, this does not mean that the leather itself is of inferior
qua lity .
Care and handling
Because of the exclusive nature of the types of leather that Audi
u ses and thei r unique p rope rties (suc h as sens it ivity to oi ls, g rease,
soi ling, etc .), you wi ll need to be somewhat careful w ith these
leathers, and a certain type of care is required. For example, dark .,.
