Basics
Safe driving habits
Please remember -safety first!
This chapter contains important information,
tips, instructions and warnings that you need to
read and observe for your own safety, the safety
of your passengers and others. We have summar­
ized here what you need to know about safety
belts, airbags, child restraints as well as child
safety. Your safety is for us priority number 1. Al­
ways observe the information and warnings in
this section -for your own safety as well as that
of your passengers.
The information in this section applies to all
model versions of your vehicle. Some of the fea­
tures described in this sections may be standard
equipment on some models, or may be optional
equipment on others. If you are not sure, ask
your authorized Audi dealer.
A WARNING
---Always make sure that you follow the in-
structions and heed the WARNINGS in this
Manual. It is in your interest and in the in­
terest of your passengers.
-Always keep the complete Owner's Litera­
ture in your Audi when you lend or sell your
vehicle so that this important information
will always be available to the driver and
passengers.
-Always keep the Owner's literature handy so
that you can find it easily if you have ques­
tions.
Safety equipment
The safety features are part of the occupant re­
straint
system and work together to help reduce
the risk
of injury in a wide variety of accident sit­
uations.
Your safety and the safety of your passengers
should not be left to chance. Advances in tech­
nology have made a variety of features available
to help reduce the risk of injury in an accident .
Safe driving
The following is a list of just a few of the safety
features in your Audi:
-
sophisticated safety belts for driver and all pas-
senger seating positions,
-
safety belt pretensioners,
-safety belt force limiters for the front seats,
-front airbags,
- knee airbags for the front seats*
-side airbags in the front seats,
-side curtain airbags with ejection mitigation
features,
-special LATCH anchorages for child restraints,
-adjustable steering column.
These indiv idual safety features, can work to­
gether as a system to he lp protect you and your
passengers in a wide range of accidents. These
features cannot work as a system if they are not
always correctly adjusted and correctly used.
Safety is everybody's responsibility!
Important things to do before driving
Safety is everybody's job! Vehicle and occupant
safety always depends on the informed and care­
ful driver.
For your safety and the safety of your passen­
gers, before driving always:
... Make sure that all lights and signals are operat­
ing correctly .
... Make sure that the tire pressure is correct.
... Make sure that all windows are clean and afford
good vis ibility to the outside.
... Secure all luggage and other items carefu lly
c::> page 176, c::> page 48.
... Make sure that nothing can interfere with the
pedals .
... Adjust front seat and mirrors correctly for your
height.
... Make sure to use the right child restraint cor­
rectly
to protect chi Id ren Q page 212, Child
safety.
... Sit properly in your seat and make sure that
your passengers do the same Q page 44, Seats
and storage. ..,.

... Fasten your safety belt and wear it properly . Al­
so instruct your passengers to fasten their
safety belts properly ¢ page 180.
What impairs driving safety?
Safe driving is directly related to the condition of
the vehicle, the driver as well as the driver 's abili­
ty to concentrate on the road without being dis­
tracted .
The driver is responsible for the safety of the ve­
h icle
and all of its occupants. If your ability to
drive is impaired, safety risks for everybody in the
veh icle increase and you also become a hazard to
everyone else on the road ¢.&,.Therefore :
... Do not let yourself be distracted by passengers
or by using a cellular telephone .
... NEVER drive when your driving ability is im­
paired (by medications, alcohol,
drugs, etc.).
... Observe all traffic laws, rules of the road and
speed limits and plain common sense.
... ALWAYS ad just you r speed to road, traffic and
weather cond itions.
... Take frequent breaks on long trips. Do not drive
for
more than two ho urs at a stretch.
... Do NOT drive when you are tired, under pres­
sure or when you are stressed.
A WARNING
Impaired dr iv ing safety increases the risk of
serious personal injury and death whenever a
vehicle is
being used.

Correct passenger
seating positions
Proper seating position for the driver
The proper driver seating position is important
for safe, relaxed driving.
Fig. 142 Correct seating pos it ion
For your own safety and to reduce the risk of in­
jury
in the event of an acc ident, we recommend
that you adjust the driver's seat to the following
position:
... Adjust the driver's seat so that you can easily
push the pedals all the way to the floor while
keeping
your knee(s) slightly bent¢.&,.
... Adjust the angle of the seatback so that it is in
an
upright position so that your back comes in
full contact with it when you drive.
... Adjust the steering wheel so that there is a d is­
tance of at least 10 in (25 cm) between the
steering wheel and your breast bone ¢fig. 142.
If not possible, see your authorized Audi deal­
ership about adaptive equipment .
... Adjust the steering wheel so that the steering
wheel and airbag cover points at your chest and
not at your face .
... Grasp the top of the steering wheel with your
elbow(s) slightly bent .
... Fasten and wear safety belts correctly
¢ page 184 .
... Always keep both feet in the footwell so that
you are in control of the vehicle at all times.
For detailed information on how to adj ust the
driver's seat, see¢ page 44, Seats and storage. ....

- Before driving, always
adjust the front pas­
senger seat properly.
- Always keep
your feet on the floor in front
of the seat. Never rest them on the seat, in­
strument panel, out of the window, etc. The
airbag
system and safety belt will not be
able to protect you properly and can even in­
crease the risk of injury in a crash.
- Never drive with
the backrest reclined or
tilted far back! The farther the backrests are
tilted back, the greater the risk of injury due
to incorrect positioning of the safety belt
and improper seating position.
- Children
must alw ays ride in child seats
¢page 212. Special precautions apply
when installing a child seat on the front
passeng er seat¢ page 188.
Proper seating positions for passengers in
rear
seats
Rear seat passengers must sit upright with both
feet on the floor consistent with their physical
size
and be properly restrained whenever the ve­
hicle is in use.
To reduce the risk of injury caused by an incorrect
seating position in the event of a sudden braking
maneuver or an accident, your passengers on the
rear bench seat must always observe the follow­
ing:
.. Make sur e that the seatback is securely latched
in the upright position ¢ page 50.
.. Keep both feet flat in the footwell in front of
the rear seat .
.. Fasten and wear safety belts properly
¢ page 184.
• Make sure that children are always properly re­
strained in a child restraint that is appropriate
for their size and age ¢ page 212.
.&. WARNING
r-= ~
Passengers who are improperly seated on the
rear seat can be seriously injured in a crash.
-Each passenger must always sit on a seat of
their own and properly fasten and wear the
safety belt belonging to that seat.
174
-Safety belts only offer maximum protection
when the seatback is securely latched in the
upright position and the safety belts are
properly positioned on the body. By not sit­
ting upright, a rear seat passenger increases
the risk of personal injury from improperly
positioned
safety belts!
Examples of improper seating positions
The occupant restraint system can only reduce
the risk of injury if vehicle occupants are properly
seated.
Improper seating positions can cause serious in­
jury
or death. Safety belts can only work when
they are properly positioned on the body. Im­
proper seating positions reduce the effectiveness
of safety belts and will even increase th e risk of
injury and death by moving the safety belt to crit­
ical
areas of the body. Improper seating positions
also i
ncrease the risk of serious injury and death
when an airbag deploys and strikes an occupant
who is not in the proper seating position. A driver
is responsible for the safety of all vehicle occu·
pants and especially for children. Therefore:
.. Never allow anyone to assume an incorrect
seating position when the vehicle is being used
c:>A.
The following bulletins list only some sample po­
sitions that will increase the risk of serious injury
and
death. Our hope is that these examples will
make you more aware of seating positions that
are dangerous.
The refore, whe never th e ve hicle is mov ing :
-never stand up in the vehicle
- never
stand on the seats
-never kneel on the seats
-never ride with the seatback reclined
- never lie down on
the rear seat
-never lean up against the instrument panel
-never sit on the edge of the seat
- never sit sideways
- never lean
out the window
- never
put your feet out the window
- never
put your feet on the instrument panel

r:;. page 171.
A WARNING
r-=-
To help prevent poisonous exhaust gas from
being drawn into the vehicle, always keep the
rear lid closed while driving.
- Never
transport objects larger than those
fitting completely into the luggage area be­
cause the rear lid cannot be fully closed.
-
If you absolutely must drive with the rear lid
open, observe the following notes to reduce
the risk of poisoning:
-
Close all windows,
-
Open all air outlets in the instrument pan-
el,
-Switch off the air recirculation,
-
Set the fresh air fan to the highest speed.
A WARNING
Always make sure that the doors, all windows
and the rear lid are securely closed and locked
to reduce the risk of injury when the vehicle is
not being used.
- After closing
the rear lid, always make sure
that it is properly closed and locked.
- Never leave your vehicle
unattended espe­
cially with the rear lid left open. A child
could crawl into
the vehicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out. Be­
ing trapped in a vehicle can lead to serious
personal injury.
- Nev er
let children play in or around the vehi­
cle.
- Never
let passengers ride in the luggage
compartment. Vehicle occupants must al­
ways be properly restrained in one of the ve­
hicle's seating positions.
(D Tips
-Air circulation helps to reduce window fog­
ging. Stale air escapes to the outside
through vents in the trim panel, on the left
side of the luggage compartment. Be sure
to keep these slots free and open.
Safe driving
-The tire pressure must correspond to the
load. The tire pressure is shown on the tire
pressure label. The tire pressure label is lo­
cated on the driver's side B-pillar. The tire
pressure label lists the recommended cold
tire inflation
pressures for the vehicle at its
maximum capacity
weight and the tires that
were on your vehicle at the time it was man­
ufactured. For recommended tire pressures
for normal load conditions, please see chap­
ter r:;. page 261.
Tie-down s
The luggage compartment is equipped with four
ti e-downs to secure luggage
and other items.
Fig. 144 Location of the tie-downs in the luggage com­
partment
Use the tie-downs to secure your cargo properly
r:;. page 176, Loading the luggage compartment.
In a collision, the laws of physics mean that even
smaller items that are loose in the vehicle will
become heavy missiles that can cause serious in­
jury . Items in the vehicle possess energy which
vary with vehicle
speed and the weight of the
item. Vehicle speed is the most significant factor.
For example, in a frontal collision at a speed of
30 mph (48 km/h), the forces acting on a 10 lbs
(4.5 kg) object
are about 20 times the normal
weight of the item. This means that the weight
of the item would suddenly be about
200 lbs (90 kg). You can imagine the injuries that
a 200 lbs (90 kg) item flying freely through the
passenger compartment could cause in a colli­
sion like this.

gers, always co rre ctly wea r safety belts
when the vehicle is moving.
-
Pregnant women , inju red, or physically im­
paired
persons must also use safety belts.
L
ike all vehicle occupants, they are more
likely to
be serio us ly injured if they do not
wea r safety belts. The best way to protect a
fetus is to protect the mother -throughout
the entire pregnancy.
Number of seats
Your Audi TI Coupe has two seating positions in
the front and two height-limited seating posi­
tions in the rear . Each seating position has a safe­
ty
belt. T he rear seat area in your Audi TT Coupe
does not have enough room fo r passengers of all
sizes. For
reasons of safety, no person taller than
4 ft 9 in (S 7 i n/1.45 m) should ever ride in the
rear seat area.
A WARNING
t--=
Not wear ing safety belts or wearing them im-
properly
increases the risk of serio us personal
injury and death.
180
- Never strap more than one person, includ­
ing
small children, into any belt. It is espe­
cially dangerous to place a safety be lt over a
child
sitting on your lap.
- Never
let more people ride in the vehicle

Automatic safety belt retractors
Every safety belt is equipped with an automatic
belt retractor on the shoulder belt. T his feature
locks the belt when the belt is pul led out fast,
during hard braking and in an accident. The belt
may also lock when you drive up or down a steep
hill or through a sharp curve. During normal driv­
ing
the belt lets you move freely.
184
Safety belt pretensioners
The safety belts on the front seats are equipped
with a belt pretensioner that helps to tighten the
safety belt and remove slack when the preten­
sioner is activated. The function of the preten­
sioner is monitored by a warning light c::> page 15.
Convertible locking retractor
Every safety belt except the one on the driver
seat is equipped with a convertib le locking retrac­
tor that must be used when the safety belt is
used to attach a child seat. Be sure to read the
important information about this feature
c::>page223 .
.&. WARNING
Improperly positioned safety belts can cause
serious injur y in an accident .:::>page 185,
Safety belt position.
-Safety belts offer optimum protection only
when the seatback is upright and belts are
properly positioned on the body .
- Always
make sure that the rear seat back­
rest to which the center rear safety belt* is
attached is securely latched whenever the
rear center safety belt is being used. If the
backrest is not securely latched, the passen­
ger will move forward with the backrest dur­
ing
sudden braking, in a sudden maneuver
and especiall y in a crash .
- Always
make sure that the rear seat back­
rest is securely latched whenever the rear
safety belt is being used. If the backrest is
not securely latched, the passenger will
move
forward with the backrest during sud­
den braking, in a sudden maneuver and es­
peciall y in a crash.
- Never
attach the safety belt to the buckle
for
another seat. Attaching the belt to the
wrong buckle will reduce safety belt effec­
tiveness and can cause serio us personal in­
jury.
- A
passenger who is not properly restra ined
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.

Improperly worn safety belts
a
~ 0 ± .. QJ
Incorrectly positioned safety belts can cause se­
vere injuries .
Wearing safety belts improperly can cause seri­
ous injury or death. Safety belts can only work
when they are correctly positioned on the body.
Improper seating positions reduce the effective­
ness of safety belts and wil l even increase the
risk of injury and death by mov ing the safety belt
to crit ica l areas of the body. Improper seating
positions also increase the risk of serious injury
and death when an airbag deploys and strikes an
occupant who is not in the correct seating posi­
tion. A driver
is responsible for the safety of all
vehicle
occupants and especially for children.
Therefore:
.. Never permit anyone to assume an incorrect
seated position in the vehicle while traveling
QA .
186
A WARNING
Improperly worn safety belts increase the risk
of serious personal injury and death whenever
a veh icle is being used.
- Always
make sure that all veh icle occupants
are corr ectly restrained and stay in a correct
seated position whenever the vehicle is be­
ing
used.
- Always read and follow all WARNINGS and
other important information Q page 183.
Safety belt tensioner
How safety belt pretensioners work
In front, side and rear-end collisions above a
particular severity
and in a rollover, safety belts
are tensioned automatically .
Pyrotechnic safety belt pretensioners
The safety belts for the front seati ng pos it io ns
are equipped with safety belt pretensioners. The
system is acti va ted by sensors in front, side and
r
ear-end collisions of great seve rity and in a roll­
over. This
tightens the belt and takes up belt
s lack ~ .& in Service and disposal of safety belt
pretensioner on page 187. Taking up the slack
helps
to reduce forward occupant movement dur­
i ng a collis ion.
A WARNING
-It is possi ble for the pretensioners to deploy
incorrect ly .
- The pyrotechnic
system can only provide
protection for one collision. If th e py rotech­
nic pretensioners deploy, the pretensioning
sys tem must be replaced.
(!) Tips
The pyrotechnic safety belt pretensioners can
o nl y
deploy once .
- The
safety belt pretensioners do not deploy
in minor frontal, side and rear-end colli­
sions .
- A
fine dust is re leased when the pyrotechnic
safety belt pretensioners deploy . This is no r­
mal and is not caused by a fire in the veh i­
cle.

Airbag system
Important information
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints. For
airbags to do their job, occupants must always
properly wear their
safety belts and be in a prop­
er seating position.
For your safety and the safety of your passen­
gers, before driving off, always:
,. Adjust the driver's seat and steering wheel
properly<::;> page 172,
,. Adjust the front passenger's seat properly
¢page 44,
,. Wear safety belts properly ¢page 183,
,. Always properly use the proper child restraint
to protect children ¢page 212.
In a collision airbags must inflate within the blink
of an eye and with considerable force. The sup­
plemental airbags can cause injuries if the driver
or the front seat passenger is not seated proper·
Ly. Therefore in order to help the airbag to do its
job, it is important, both as a driver and as a pas­
senger to sit properly at all times.
By keeping room between your body and the
steering wheel and the front of the passenger
compartment, the airbag can inflate fully and
completely and provide supplemental protection
in certain frontal collisions r=.> page 172, Correct
passenger seating positions . For details on the
operation of the seat adjustment controls
¢page45.
It's especially important that children are proper­
ly restrained¢ page 212.
There is a lot that the driver and the passengers
can and must do to help the individual safety fea­
tures installed in your Audi work together as a
system.
Proper seating position is important so that the
front airbag on the driver side can do its job. If
you have a physical impairment or condition that
prevents you from sitting properly on the driver
seat wi th the safety belt properly fastened and
188
reaching the pedals, or if you have concerns with
regard to the function or operation of the Ad­
vanced Airbag
System, please contact your au­
thorized Audi
dealer or qualified workshop, or
call Audi Customer Relations at 1-800-822-2834

When the airbag system deploys , a gas generator
will fill the airbags, break open the padded cov­
ers, and inflate between the steering wheel and
the driver and between the instrument panel and
the front passenger. The airbags will deflate im­
mediately after deployment so that the front oc­
cupants can see through the windshield again
without interruption.
All of this takes place in th e blink of an eye, so
fast that many people don't even realize that the
airbags have deployed. The airbags also inflate
with a great deal of force and nothing should be
in their way when they deploy . Front airbags in
combination with properly worn safety belts slow
down
and limit the occupant's forward move­
ment. Together they help to prevent the driver
and front seat passenger from hitting parts of
the inside the vehicle while reducing the forces
acting on the occupant during the crash. In this
way they help to reduce the risk of injury to the
head and upper body in the crash. Airbags do not
protect the arms or the lower parts of the body.
Both
front a irbags will not inflate in all frontal
collisions. The triggering of the airbag system de­
pends on the vehicle deceleration rate caused by
the collision and registered by the electronic con­
trol unit. If this rate is below the reference value
programmed into the control unit, the airbags
will not be triggered, even though the car may be
badly
damaged as a result of the co llision. Vehi ­
cle
damage, repair costs or even the lack of vehi­
cle
damage is not necessarily an indication of
whether an airbag should inflate or not.
Since the circumstances will vary considerably
between one collision and another, it is not possi ­
ble to define a range of vehicle speeds that will
cover every possible kind
and angle of impact
that will always trigger the airbags. Important
factors include, for example, the nature (hard or
soft) of the object which the car hits, the angle of
impact, vehicle speed, etc. The front airbags will Iii>
