What impairs driving safety?
Safe driving is directly related to the condition of the
vehicle, the driver as well as the driver's ability to concen­
trate on the road without being distracted.
The driver is responsible for the safety of the vehicle and all
of its occupants. If your ability to drive is impaired, safety risks for everybody in the vehicle increase and you also
Controls and equip­ ment Safety first Vehicle operation
become a
hazard to everyone else on the road =>&, .There ­
fore:
- Do not let yourself be distracted by passengers or by
using a cellular telephone.
- NEVER drive when your driving ability is impaired (by
medications, alcohol, drugs, etc .).
- Observe all traffic laws, rules of the road and speed limits
and plain common sense.
- ALWAYS adjust your speed to road, traffic and weather
conditions.
- Take frequent breaks on long trips. Do not drive for more
than two hours at a stretch.
- Do NOT drive when you are tired, under pressure or when
you are stressed.
in. WARNING
Impaired driving safety increases the risk of serious personal
injury and death whenever a vehicle is being used. •

Driving Safely -
----------------
& WARNING (continued)
• Always adjust the driver's seat and the steering wheel so that
there are at least 4 inches (10 cm) between the knees and the
lower part of the instrument panel.
• Always hold the steering wheel on the outside of the steering
wheel rim with your hands at the 9 o'clock and 3 o'clock positions
to help reduce the risk of personal injury if the driver's airbag inflates .
• Never hold the steering wheel at the 12 o'clock position or with
your hands at other positions inside the steering wheel rim or on
the steering wheel hub. Holding the steering wheel the wrong way
can cause serious injuries to the hands, arms and head if the
driver's airbag inflates
• Pointing the steering wheel toward your face decreases the
ability of the supplemental driver's airbag to protect you in a colli­
sion .
• Always sit in an upright position and never lean against or
place any part of your body too close to the area where the airbags
are located.
• Before driving, always adjust the front seats and head
restraints properly and make sure that all passengers are properly
restrained .
• Never adjust the seats while the vehicle is moving. Your seat
may move unexpectedly and you could lose control of the vehicle.
• 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 always ride in child seats=>
page 168. Special
precautions apply when installing a child seat on the front
passenger seat=>

ment Safety first Vehicle operation
Proper seating position for the front
passenger
The proper front passenger seating position is important
for safe, relaxed driving.
For your own safety and to reduce the ris k of injury in the
event of an accident, we recommend that you adjust the
seat for the front passenger to the following pos ition:
- Move the front passenger seat back as far as possible.
There must be a minimum of 10 inches (25 cm) between
the breastbone and the instrument panel =>
&.
- Adjust the angle of the seatback so that it is in an upright
position and your back comes in full contact with it
whenever the vehicle is moving.
- Adjust the head restraint so that the upper edge is as
even with the top of your head as possible but not lower
than eye level and so that it is as close to the back of your
head as possible =>
page 132.
-Keep both feet flat on the floor in front of the front
passenger seat.
- Fasten and wear safety belts correctly=>
page 141.
For detailed information on how to adjust the front passenger's
seat, see => page 87.
& WARNING
Front seat passengers who are unbelted, out of position or too
close to the airbag can be seriously injured or killed by the airbag
as it unfolds. To help reduce the risk of serious personal injury : .,

& WARNING (continued)
• Always make sure each person in the vehicle properly adjusts
their head restraint. Each head restraint must be adjusted
according to occupants' size so that the upper edge is as even
with the top of the person's head, but no lower than eye level and so it is as close to the back of to the head as possible .
• Never attempt to adjust head restraint while driving.
If you
have driven off and must adjust the driver headrest for any reason,
first stop the vehicle safely before attempting to adjust the head
restraint.
• Children must always be properly restrained in a child restraint
that is appropriate for their age and size~
page 168. •
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 injury or
death. Safety belts can only work when they are properly
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 proper seating
position. A driver is responsible for the safety of all vehicle
occupants and especially for children. Therefore:
- Never allow anyone to assume an incorrect seating posi­
tion when the vehicle is being used::::;,
&-
The following bullets list only some sample positions that will
increase the risk of serious injury and death . Our hope is that these
Controls and equip­
ment Safety first Vehicle operation
examples will make you more aware of seating positions that are
dangerous.
Therefore, whenever the
vehicle is moving:
• 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
• never rest your feet on the seat cushion or back of the seat
• never ride in the footwell
• never ride in the cargo area
& WARNING
Improper seating positions increase the risk of serious personal
injury and death whenever a vehicle is being used.
• Always make sure that all vehicle occupants stay in a proper
seating position and are properly restrained whenever the vehicle
is being used. •

& WARNING (continued)
• Never place or install floor mats or other floor coverings in the
vehicle that cannot be properly secured in place to prevent them
from slipping and interfering with the pedals or the ability to
control the vehicle .
• Never place or install floor mats or other floor coverings on top
of already installed floor mats. Additional floor mats and other
coverings will reduce the size of the pedal area and interfere with
the pedals.
• Always properly reinstall and secure floor mats that have been
taken out for cleaning.
• Always make sure that objects cannot fall into the driver foot­
well while the vehicle is moving. Objects can become trapped
under the brake pedal and accelerator pedal causing a loss of
vehicle control . •
Stovving luggage
Loading the luggage compartment
All luggage and other objects must be properly stowed
and secured in the luggage compartment.
Loose items in the luggage compartment can shift
suddenly, changing vehicle handling characteristics. Loose items can also increase the risk of serious personal injury in
a sudden vehicle maneuver or in a collision.
- Distribute the load evenly in the lugg age compartment.
- Always place and properly secure heavy items in the
luggage compartment as far forward as possible.
Controls and equip­
ment Safety first
Vehicle operation
& WARNING
Improperly stored luggage or other items can fly through the
vehicle causing serious personal injury in the event of hard braking or an accident. To help reduce the risk of serious personal injury:
• Always put objects, for example, luggage or other heavy items
in the luggage compartment .
• Always secure objects in the luggage compartment using the
tie-down eyelets and suitable straps.
& WARNING
Heavy loads will influence the way your vehicle handles. To help
reduce the risk of a loss of control leading to serious personal
injury :
• Always keep in mind when transporting heavy objects, that a
change in the center of gravity can also cause changes in vehicle
handling:
-Always distribute the load as evenly as possible.
- Place heavy objects as far forward in the luggage compart-
ment as possible.
• Never exceed the Gross Axle Weight Rating or the Gross
Vehicle Weight Rating specified on the safety compliance sticker on the left door jamb . Exceeding permissible weight standards
can cause the vehicle to slide and handle differently.
• Please observe information on safe driving=:>
page 128.
& WARNING
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

Safety belts
General notes
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety belts are necessary, how
they work and how to adjust and wear them correctly.
- Read all the information that follows and heed all of the
instruct ions and WARNINGS.
& WARNING
Not wearing safety belts or wearing them improperly increases
the risk of serious personal injury and death.
• Safety belts are the single most effective means available to
reduce the risk of serious injury and death in automobile acci­
dents . For your protection and that of your passengers , always
wear the safety belts properly when the vehicle is moving.
• Pregnant women, injured, or physically impaired persons must
also use safety belts . Like all vehicle occupants, they are more
likely to be seriously injured if they do not wear safety belts . The
best way to protect a fetus is to protect the mother -throughout
the entire pregnancy. •
Number of seats
Your Audi TI Roadster has two seating positions. Each seating posi ­
tion has a safety belt.
Controls and equip­ ment Safety first
Vehicle operation
& WARNING
Not wearing safety belts or wearing them improperly increases
the risk of serious personal injury and death .
• Never strap more than one person, including small children,
into any belt. It is especially dangerous to place a safety belt over
a child sitting on your lap.
• Never let more people ride in the vehicle than there are safety
belts available.
• Be sure everyone riding in the vehicle is properly restrained
with a separate safety belt or child restraint. •
Safety belt warning light .4

Because the occupants in th is vehicle are not using safety belts
~ page 138, fig. 122, they will keep moving at the same speed the
vehicle was moving just before the crash, un til some thing stops
them -here, the wall ~ page 138 , fig . 123.
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 , th ese forces are
even greater.
People who do not use safety bel ts 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. •
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!

wearing a safety belt is

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

Safety belts
violently into the steering wheel, instrument panel, windshield, or
whatever else is in the way ~ fig. 124 . This impact with the vehicle
interior has all the 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 o f accidents. Although your Audi is
equipped with airbags, all vehicle occupants, including the driver,
must wear safety belts correctly in order to minimi ze 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. •
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. 125 Driver is prop·
erly 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. .,.
