2017 AUDI TT COUPE ECU

Safety belts
Although these examples are based on a frontal
collision, safety belts can also substantially re­
duce the risk of injury in other kinds of crashes.
So, whether you're on a long trip or just going to
the corner store, always buckle up and make sure
others do, too . Accident statistics show that vehi­
cle occupants properly wearing safety belts have
a lower risk of being injured and a much better
chance of surviving an accident. Properly using
safety belts also greatly increases the ability of
the supplemental airbags to do their job in a col­
lision. For this reason, wearing a safety belt is le­
gally required in most countries including much
of the United States and Canada .
Although your Audi is equipped with airbags, you
still have to wear the safety belts provided. Front
airbags, for example, are activated only in some
frontal collisions. The front airbags are not acti­
vated in all frontal collisions, in side and rear col­
lisions, in roll overs or in cases where there is not
enough deceleration through impact to the front
of the vehicle. The same goes for the other airbag
systems in your Audi . So, always wear your safety
belt and make sure everybody in your vehicle is
properly restrained!
Important safety instructions about safety
belts
Safety belts must always be correctly positioned across the strongest bones of your body.
.. Always wear safety belts as illustrated and de­
scribed in this chapter.
.. Make sure that your safety belts are always
ready for use and are not damaged.
A WARNING
Not wearing safety belts or wearing them im­
properly increases the risk of serious personal
injury and death. Safety belts can work only
when used correctly.
- Always fasten your safety belts correctly be­
fore driving off and make sure all passen­
gers are correctly restrained.
- For maximum protection, safety belts must
always be positioned properly on the body.
192
- Never strap more than one person, includ­
ing small children, into any belt.
- Never place a safety belt
over a child sitting
on your lap.
- Always keep feet in the footwell in front of
the seat while the vehicle is being driven.
- Never let any person ride with their feet on
the instrument panel or sticking out the
window or on the seat.
- Never remove a safety belt while the vehicle
is moving. Doing so will increase your risk of
being injured or killed.
- Never wear belts twisted.
- Never wear belts over rigid or breakable ob-
jects in or on your clothing, such as eye glasses, pens, keys, etc ., as these may cause
injury.
- Never allow safety belts to become dam­
aged by being caught in door or seat hard­
ware.
- Do not wear the shoulder part of the belt
under your arm or otherwise out of position.
- Several layers of heavy clothing may inter­
fere with correct positioning of belts and re•
duce the overall effectiveness of the system.
- Always keep belt buckles free of anything
that may prevent the buckle from latching
securely.
- Never use comfort clips or devices that cre­
ate slack in the shoulder belt. However, spe­
cial clips may be required for the proper use
of some child restraint systems .
- Torn or frayed safety belts can tear and
damaged belt hardware can break in an acci­
dent. Inspect belts regularly. If webbing,
bindings, buckles, or retractors are dam­
aged, have belts replaced by an authorized
Audi dealer or qualified workshop.
- Safety belts that have been worn and loaded
in an accident must be replaced with the
correct replacement safety belt by an au­
thorized Audi dealer. Replacement may be necessary even if damage cannot be clearly
seen . Anchorages that were loaded must al­
so be inspected.
- Never remove, modify, disassemble, or try
to repair the safety belts yourself.

Automatic safety belt retractors
Every safety belt is equipped with an automatic
belt retractor on the shoulder belt . Th is feature
l ocks the belt when the be lt is p ulled out fast,
during hard braking and i n an accide nt. T he belt
may a lso lock when you drive up or down a steep
hi ll or through a sharp curve . During no rma l driv­
ing the be lt lets you move freely.
Safety belt pretensioners
The safe ty belts on the front sea ts are equipped
with a be lt pretensione r that helps to t igh ten the
Safet y bel ts
safety belt and remove s lack when the preten­
sioner is activated. The function of the preten­
s ioner is monitored by a warn ing light ¢

Convertible locking retractor
Eve ry safe ty belt except the one on the drive r
seat is equipped with a convertible loc king retrac­
tor that
must be used when the safety be lt is
u sed to attach a child seat. Be sure to read the
impo rtant information about this feature
¢ page 232.
A WARNING
-Improperly positioned safety belts can cause
serious injury in an accident¢
page 194,
Safety belt position.
- Safety belts offer optimum protection on ly
when the seatback is upright and belts are properly posit ioned on the body .
- Always make sure that the rear seat back ­
rest is secu rely latched whenever the rear
safety belt is being used . If the backrest is
not securely latched, the passenge r will
move forw ard with the backrest during s ud­
den braking, in a sudden mane uver and es­
pecia lly in a crash.
- Neve r attach the safety bel t to the buckle
for anot her seat . Attac hing the be lt to the
wrong buckle will reduce safety be lt effec ­
tiveness and can cause serious personal in­
jury.
- A passenger who is not properly rest rained
can be seriously injured by the safety belt it­
self when it moves from the stronger parts
of the body into critical areas like the abdo­
men .
- Always lock the convertible locking retractor
when yo u are securing a c hild seat in the ve­
h icle

Correct belt position is the key to getting maxi­
mum protection from safety belts.
Fig . 157 Safety belt pos ition
A WARNING
Improperly positioned safety belts can cause
ser ious personal injury in an accident.
- The shoulder belt should lie as close to the
center of the collar bone as possible and
should fit well on the body. Hold the belt above the latch tongue and pull it evenly
across the chest so that it sits as low as pos­
sible on the pelvis and there is no press ure
on the abdomen. The belt should always fit
snugly ¢

@ Tips
The chi ld seats listed in categories A to C have
been statically tested by Audi only for the Ad­
vanced Airbag function .
Important safety instructions for using
child safety seats
Correct use of child safety seats substantially re­
duces the risk of injury in an accident!
As the driver, you are responsible for the safety
of everybody in the vehicle, especially children:
~ Always use the right child safety seat for each
child and a lways use it properly~
page 22 7.
~ Always carefully follow the child safety seat
manufacturer's instructions on how to route
the safety belt properly through the child safe­
ty seat .
~ When using the vehicle safety be lt to install a
child safety seat , you must first activate the
convertible locking retractor on the safety be lt
to prevent the child safety seat from moving
~ page 232.
~ Push the child safety seat down w ith your full
weight to get the safety be lt rea lly t ight so that
the seat cannot move forward and sideways more than 1 in (2 .5 cm).
~ Secure unused safety belts on the rear seat
~ page 227.
Always remember: Even though your vehicle is
equipped with an Advanced Airbag system, all
children, especially those 12 years and younger,
should always ride in the back seat properly re­
stra ined for their age and size.
_&, WARNING
Not using a ch ild safety seat , using the w rong
child sa fety seat or imp roperly installing a
child restraint increases the risk of serious
personal injury and death.
- All vehicle occupants and especia lly children
must be restrained properly whenever riding
in a vehicle . An unrestrained or improperly
restrained child could be injured by striking
the interior or by being ejected from the ve­ hicle during a sudden maneuver or impact.
Ch ild safety
An unrestrained or improperly restrained
child is also at greater r isk of injury or death
through contact with an inf lating airbag.
- Commercially available child safety seats
are required to comply with U.S . Federal
Motor Vehicle Safety Standard (FMVSS) 213
(in Canada CMVSS 213) .
- When buying a child restra int, select one
that fits your chi ld and the vehicle.
- Only use child restraint systems that fully
contact the flat portion of the seat cush­
ion . The child restraint must not tip or
lean to either side. Audi does not recom­
mend using child safety seats that rest on
legs or tube-like frames. They do not pro­
vide adequate contact with the seat.
- Always heed all lega l requirements per­
ta ining to the insta llation and use of child
safety seats and carefully follow the in­
structions provided by the manufacturer
of the seat you are using .
- Never allow children under 4 ft
9 in (57 in/
1.45 m) to wear a normal safety belt . H ow­
eve r, the rear seat in the TT Coupe is de­
signed to permit children who are between
4 ft 3 in (1.3 m) and 4
ft 9 in (57 in/1.45 m)
tall to use the available three-point lap and
shoulder safety belts.
- Never let more than one child occupy a chi ld
safety seat .
- Never let babies or o lder children ride in a
veh icle while sitting on the lap of another
passenger.
- Holding a child in your arms is never a sub­
stitute for a child restraint system .
- The strongest person cou ld not ho ld the
ch ild with the forces that exist in an acci­
dent . The child will strike the interior of
the vehicle and can also be struck by the passenger.
- The child and the passenger can also in­
jure each other in an accident.
- Never install rear-fac ing child safety seats
or infant car riers on the front passenger
seat. A child w ill be seriously injured and
can be killed when the passenger a irbag in­
flates -even with an Advanced Airbag Sys­
tem .

A toddler or child is usually too large for an in­
fant restraint if it is more than one year old and
weighs more than 20 lbs (9 kg) .
T oddlers and children who are o lder 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 ch ild safety seat cert ified
for the ir s ize and weight ¢

¢ fig. 173 .
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
chi ld in a fo rward-facing chi ld safety seat. It is a
ve ry dangero us p lace for an infant or a la rger
ch ild in a rearward -facing seat.
_.6 WARNING
-Not using a ch ild safety seat, using the wrong
child safety seat or improper ly installing a
child restraint increases the risk of serious
personal injury and death in a collis ion or oth­
er emergency situation.
- Children on the front seat of any car, even
with Advanced Airbags, can be seriously in­
jured or even killed when an a irbag inflates.
A ch ild 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 inflates - even with an Ad­
vanced Airbag System.
- T he inflating a irbag w ill hit the child safety
seat or infant carrier with great force and
will smash the ch ild safety seat and chi ld

If exceptional c ircumstances req uire the use
of a forward -facing chi ld restraint on the
front passenger's seat, the child's safety and
well-being req uire that the following special
precautions be taken:
- Make sure the forward-fac ing seat has been
des igned 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 into
the rearmost pos ition of the passenger
seat's fore and aft adjustment range, and as
far away from the airbag as possible before installing the ch ild rest raint .
- Always make sure that nothing prevents the
front passenger's seat from being moved to
the rea rmost pos ition in its fore and aft ad­
justment range.
- Always make sure the backrest is in an up­
right position.
- Never p lace or use any electr ica l device
(such as a laptop, CD player, e lectron ic
games device, power inve rter or sea t hea ter
for child seats) on the front passenger seat
if the device is connected to the 12-volt

- Make sure that there are no wet objects
(such as a wet towe l) and no water or other
liquids on the front passenger seat cushion .
- Never place objects on the seat (such as a
laptop, CD player, electronic games device,
power inverter or seat heater for child
seats) . These may influence the e lectr ica l

Booster seats and safety belts
Properly used booster sea ts 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 in/1 .45 m) tall.

The vehicle's safety belts alone wi ll not fit most
children 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 be lt 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 convertib le locking retractor
when us ing the ve hicle's safety belt to restra in
a child on a booster seat .
.., The shoulder belt must lie as close to the cen­
ter of the child's collar bon e as possib le and
must l ie flat and snug on the uppe r body.
It
must never lie across the throat or neck. The
lap belt must lie ac ross the pelvis and never
across t he stomach or abdomen . Make sure the
belt lies flat and snug. Pu ll on the belt to tight­
en if necessary.
.. Secure unused safety belts on the rear seat
¢page 227.
Children up to at least 8 years o ld (over 40 lbs or
18 kg) are best protected in child safety seats de ­
s igned for their age and weight. Experts say that
the skeletal structure, part icu larly the pelvis, of
these children is not fully developed, and they must not use the vehicle safety belts without a
su itab le child restra int.
It is usually best to put these children in appro­
pr iate booster seats . Be sure the booster seat
meets a ll applicab le safety standards .
Booster seats raise the seating position of the
c hi ld and reposition both the lap and shoulder
parts of the safety belt so that they pass across
the chi ld's body in the right places . The rou ting of
the be lt over the ch ild's body is very important
fo r the child's protection, whet he r or not a boos ­
ter seat is used. C hildren age 12 and under m ust

Never use the lap belt port ion of the vehicle's
safety belt alone to restra in any child, regard less
of how b ig the child is. A lways remember that
c hi ldre n do not have the pronounced pe lvic struc ­
ture requ ired for the proper function of lap belt

A WARNING
-The rear seat area is too small to safe ly
transport passengers taller than 4 ft 9 in
(57 in/1.45 m).
-
- Persons taller than 4 ft 9 in (57 in/1.45 m) as well as children in booster seats who are
too close to the rear window and roof can
suffer severe head and neck injur ies when
the rear lid is closed o r in a crash.
- The m inimum clearance betwee n the pas­
sengers' heads and the rear window must
never - under any circumstances - be less
than 1 in ( 2.5 cm) whe n the passenge rs s its
f ully up right .
- Always make sure tha t the rear seat passen­

cl osed.
Booster seats on the front seat
Ch ild ren aged about 7 years and older and weigh ­
ing more than 55 lbs (25 kg) who are between
4 ft 3 in (5 1 in/1.30 m) and 4 ft 9 in (57 in/
1.45 m) tall may in exceptional circumstances
ride on the front passenger's seat. Children less
than 4 ft 9 in (57 in/1.45 m) tall must s it on a
certified booster seat and properly wear the vehi ­
cle 's three-poin t lap and shoulder safety be lt .
Always securely latch the passenger seat at t he
