2009 AUDI TT COUPE Owners Manual

Fig. 102 The vehicle
crashes into the wall.
The physical principles are simple. Both the vehicle and the passen­
gers possess energy which varies with vehicle speed and body
weight . Engineers call this energy "kinetic energy."
The higher the speed of the vehicle and the greater the vehicle's
weight, the more energy that has to be "absorbed" in the crash.
Vehicle speed is the most significant factor. If the speed doubles
from 15 to 30 mph (25 to 50 km/h), the energy increases 4 times!
Because the occupants in this vehicle are not using safety belts
~ page 126, fig . 101, they will ke ep moving at the same sp eed the
vehicle was moving just before the crash, until something stops them -here, the wall~ fig. 102 .
The same principles apply to people sitting in a vehicle that is
involved in a frontal collision . Even at city speeds of 20 to 30 mph
(30 to 50 km/h), the forces acting on the body can reach one ton
(2,000 lbs, or 1,000 kg) or more . At higher speeds , these forces are
even greater.
People who do not use safety belts are also not attached to their
vehicle. In a frontal collision they will also keep moving forward at
the speed their vehicle was travelling just before the crash. Of
course, the laws of physics don't just apply to frontal collisions, they
determine what happens in all kinds of accidents and collisions. •

Safety belts
What happens to occupants not wearing
safety belts?
In crashes unbelted occupants cannot stop themselves
from flying forward and being injured or killed. Always
wear your safety belts!

driver
Unbelted occupants are not able to resist the tremendous forces of
impact by holding tight or bracing themselves. Without the benefit
of safety restraint systems, the unrestrained occupant will slam
violently into the steering wheel , instrument panel , windshield , or
whatever else is in the way~ fig. 103 . This impact with the vehicle
interior has all th e energy they had just before the crash.
Never rely on airbags alone for protection. Even when they deploy,
airbags provide only additional protection. Airbags are not

supposed to deploy in all kinds of accidents. Although your Audi is
equipped with airbags, all vehicle occupants, including the driver, must wear safety belts correctly in order to minimize the risk of
severe injury or death in a crash.
Remember too, that airbags will deploy only once and that your
safety belts are always there to offer protection in those accidents
in which airbags are not supposed to deploy or when they have
already deployed. Unbelted occupants can also be thrown out of the
vehicle where even more severe or fatal injuries can occur.
It is also important for the rear passengers to wear safety belts
correctly. Unbelted passengers in the rear seats endanger not only
themselves but also the driver and other passengers:::::,
page 127,
fig. 104. In a frontal collision they will be thrown forward violently,
where they can hit and injure the driver and/or front seat passenger. •
Safety belts protect
People think it's possible to use the hands to brace the
body in a minor collision. It's simply not true!
Fig . 105 Driver is prop­
er ly restrained in a
sudden braking
maneuver.
Safety belts used properly can make a big difference . Safety belts
help to keep passengers in their seats, gradually reduce energy
levels applied to the body in an accident, and help prevent the uncontrolled movement that
can cause serious injuries. In addition,
safety belts reduce the danger of being thrown out of the vehicle.
Safety belts attach passengers to the car and give them the benefit
of being slowed down more gently or "softly" through the "give" in
the safety belts, crush zones and other safety features engineered
into today's vehicles. By "absorbing" the kinetic energy over a
longer period of time, the safety belts make the forces on the body
more "tolerable" and less likely to cause injury.
Although these examples are based on a frontal collision, safety belts can also substantially reduce 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 . Acci­
dent statistics show that vehicle 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
collision . For this reason, wearing a safety belt is legally 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 activated in
all frontal collisions, in side and rear collisions, 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 every­ body in your vehicle is properly restrained! •
Important safety instruct~ons about safety
belts
Safety belts must always be properly positioned across
the strongest bones of your body.
Always wear safety belts as illustrated and described in
this chapter. _,

- Make sure that your safety be lt s ar e alw ay s re ady fo r use
a nd are not damaged.
& WARNING
Not wearing safety belts or wearing them improperly increases
the risk of ser ious personal injury and death . Safety belts can work
only when used correctly.
• Always fasten your safety belts correctly before driving off and
make sure all passengers are properly restrained .
• For maximum protection , safety belts must always be posi­
tioned correctly on the body.
• Never strap more than one person , including small children ,
into any single safety 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 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 objects in or on your
clothing, such as eye glasses, pens, keys , etc ., as these may cause
injury .
• Never wear the shoulder part of the belt under your arm or
otherwise out of position .
• Several layers of heavy clothing may interfere with correct posi­
tioning of belts and redu ce their effectiveness .
• Always keep belt buckles free of anything that may prevent the
bu ckle from latching securely .
• Never use comfort clips or devices that create slack in the
shoulder belt . However , special clips may be required for the
correct use of some child restraint systems.

& WARNING !continued)
• Never allow safety belts to become damaged by being caught
in door or seat hardware.
• Torn or frayed safety belts can tear and damaged belt hardware
can break in an accident . Inspect belts regularly . If webbing , bind ­
ings, buckles, or retractors are damaged, have belts replaced by an
authori zed 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
authorized Audi dealer or qualified workshop . Replacement may
be necessary even if damage cannot be clearly seen. Anchorages
that were loaded must also be inspected .
• Never remove , modify , disassemble, or try to repair the safety
belts yourself .
• Always keep the belts clean. Dirty belts may not work properly
and can impair the function of the inertia reel

To provide maximum protection, safety belts must always
be positioned correctly on the wearer's body.
Adjust the front seat and head restraint properly
=> page 69, "General recommendations ".
Hold the belt by the tongue and pull it evenly across the
chest and pelvis=>&.
- Insert the tongue into the correct buckle of your seat
until you hear it latch securely => page
129, fig. 106.
Pull on the belt to make sure that it is securely latched in
the buckle.
Automatic safety belt retractors
Every safety belt is equipped with an automatic belt retractor on the
shoulder belt. This feature locks the belt when the belt is pulled 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 driving the belt lets you move freely.
Safety belt pretensioners
The safety belts on the front seats are equipped with a belt preten­
sion er that helps to tighten the safety belt and remove slack when
the pretensioner is activated. The function of the pretensioner is
monitored by a warning light:::::,
page 78, "Airbag system
t!A (USA models) /!.ir (Canada models)".
Switchable locking feature
Every safety belt except the one on the driver seat is equipped with
a switchable locking feature that
must be used when the safety belt
is used to attach a child seat. Be sure to read the important informa ­
tion about this feature:::::,
page 168.
& WARNING
Improperly positioned safety belts can cause serious injury in an
accident :::::,
page 130, "Safety belt position".
• Safety belts offer optimum protection only when the seat back
is upright and belts are properly positioned on the body.
• Never attach the safety belt to the buckle for another seat.
Attaching the belt to the wrong buckle will reduce safety belt
effectiveness and can cause serious personal injury.
• A passenger who is not properly restrained can be seriously
injured by the safety belt itself when it moves from the stronger
parts of the body into critical areas like the abdomen.
• Always lock the convertible locking retractor when you are
securing a child seat in the vehicle:::::,

will increase your risk of being injured or killed .•
Improperly worn safety belts
Incorrectly positioned safety belts can cause severe inju­
ries.
Wearing safety belts improperly can cause serious injury or
death. Safety belts can only work when they are correctly positioned on the body. Improper seating positions reduce
the effectiveness of safety belts and will even increase the
risk of injury and death by moving the safety belt to critical
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
position . A driver is responsible for the safety of all vehic le
occupants and especially for children. Therefore :
- Never permit anyone to assume an incorrect sitting posi­
tion in the vehicle while traveling=>&.
& WARNING
Improperly worn safety belts increase the risk of serious personal
injury and death whenever a vehicle is being used.
• Always make sure that all vehicle occupants are correctly
restrained and stay in a correct seating position whenever the
vehicle is being used.
• Always read and heed all WARNINGS and other important infor­
mation
=> page 128. •

Safety belt pretensioners
How safety belt pretensioners work
In front and side collisions above a particular severity,
safety belts in use are tensioned automatically.
T he safety belts for the front seating positions are equipped with
safety belt prete nsioners. The system is activated by sensors in
front and side co llisions of great severity. This tightens the belt and
takes up belt slack~
& in "Se rvice and d isposal of safety belt
pretensioner". Taking up the slack he lps to reduce forward occupant
movement during a co llision .
[ i] Tip s
The safety belt p retensione r can on ly be activated once.
• I n minor frontal and side collis ions, in rear -end collisions, in a
rollover and in accidents involving very litt le impact fo rce, the safety
belt pretensioner are not activated.
• When the safety be lt pretensioner is activated, a f ine dust is
released . This is normal and is not caused by a fire in the vehicle.
• The relevant safety require ments must be observed when the
vehicle or components of the system are scrapped. A qualified deal ­
ership is fami liar with these regulat ions and wil l be p leased to pass
on the information to you.
• Be su re to observe al l safety, env ironmen ta l and othe r regula ­
tions if the vehicle or individual parts of the system, particu larly the
safety belt or airbag, are to be disposed . We recommend you have
your authorized Audi dealer perform this service for you. •
