Safety belts -----------------=------
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
correctly wear safety belts 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
Vehicles with five seats: Your vehicle has two front seats and three
rear seats. Each seating position has a safety belt.
Vehicles with six seats:* Your vehicle has two front seats, two seats
in the second row and two seats in the third row. Each seating posi­
tion has a safety belt.
Controls and equip­ ment Safety first
Vehicle operation Vehicles
with seven seats:* Your vehicles has two front seats, three
seats in the second row and two seats in the third row. Each seating
position has a safety belt.
& 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,.
Your vehicle has a warning system for the driver and front
seat passenger (on USA models only) to remind you about
the importance of buckling-up.

Because the passengers of this vehicle are not using safety belts
=:>
page 232, fig. 240, they will keep moving at the same speed the
vehicle was moving just before the crash, until something stops
them -here, the wall =:>
page 232, fig. 241.
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 greater speeds, these forces are
even higher.
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. •
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!
Safety first

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. 242. 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 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=:> fig. 243. In a
frontal collision they will be thrown forward violently, where they can hit and injure the driver and/or front seat passenger. •

[ i] Tips
• The shoulder belt part should route approximately over the
middle of your shoulder -under no circumstances should it route
over your neck and throat area~
& in "Safety belt position" on
page 236.
• With the front seats, the height adjustment of the seat can also
be used to adjust the position of the safety belts. •
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 vehicle
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.

Safety be lt pretensioners
How safety belt pretensioners work
In front, side and rear-end collisions above a particular
severity and in a rollover, safety belts are tensioned auto ­
matically.
The safety belts are equipped with safety belt pretensioners . The
system is activated by sensors in front, side and rear -end collisions
of great severity and in a rollover. This tightens the belt and takes up
belt slack ~
& in "Service and disposal of safety belt pretensioner"
on
page 240. Taking up the slack helps to reduce forward occupant
movement during a collision.
0 Note
Never let the belt remain over a rear seat back that has been folded
forward.
[ i] Tips
The safety belt pretensioner can only be activated once.
• In minor frontal and side collisions, in rear -end collisions and in
accidents involving very little impact force, the safety belt preten ­
sioner are not activated .
• When the safety belt pretensioners are activated, a fine dust is
released . This is normal and is not caused by a fire in the vehicle .
• The relevant safety requirements must be observed when the
vehicle or components of the system are scrapped. An authorized ._

Airbag system
Important things to know
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 proper seating position.
For your safety and the safety of your passengers, before
driving off, always:
- Adjust the driver's seat and steering wheel properly
=>
page 222,
-Adjust the front passenger's seat properly=> page 93,
-Wear safety belts properly=> page 234,
- Always properly use the proper child restraint to protect
children =>
page 263.
In a collision, airbags must inflate within the blink of an eye and with
considerable force . The supplemental airbags can cause injuries if
the driver or the front seat passenger is not seated properly. There ­
fore in order to help the airbag to do its job, it is important, both as
a driver and as a passenger 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 =>
page 222, "Proper occupant seating positions". For
details on the operation of the seat adjustment controls=>
page 93.
It's especially important that children are properly restrained
=>
page 263.
Controls and equip­ ment Safety first Vehicle operation
There is a lot that the driver and the passengers can and must do to
help the individual safety features 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
with the safety belt properly fastened and reaching the pedals, or if
you have concerns with regard to the function or operation of the
Advanced Airbag System, please contact your authorized Audi dealer or qualified workshop, or call Audi Customer CARE at 1-800-
822 -2834 for possible modifications to your vehicle.
When the airbag system deploys, a gas generator will fill the
airbags, break open the padded covers, and inflate between the
steering wheel and the driver and between the instrument panel
and the front passenger. The airbags will deflate immediately after
deployment so that the front occupants can see through the wind ­
shield again without interruption .
All of this takes place in the 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 movement .
Together they help to prevent the driver and front seat passenger
from hitting parts of the inside of 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 airbags will not inflate in all frontal collisions. The trig­
gering of the airbag system depends on the vehicle deceleration
rate caused by the collision and registered by the electronic control
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 collision. Vehicle damage,

Child restraints on the front seat -some
important things to know
- Be sure to read the important information and heed the
WARNINGS for important details about children and
Advanced Airbags :=>
page 263.
Even though your vehicle is equipped with an Advanced Airbag
System, make certain that all children, especially those 12 years and
younger, always ride in the back seat properly restrained for their age and size . 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 child in a forward -facing child safety seat. It
can be a very dangerous place for an infant or a child in a rearward ­
facing seat.
The Advanced Airbag System in your vehicle has been certified to
comply with the requirements of United States Federal Motor
Vehicle Safety Standard 208 as applicable at the time your vehicle
was manufactured.
The Standard requires the front airbag on the passenger side to be
turned off ("suppressed") if a child up to about one year of age
restrained in one of the rear-facing or forward-facing infant
restraints listed in Federal Motor Vehicle Safety Standard 208 with
which the Advanced Airbag System in your vehicle was certified has been installed on the front passenger seat. For a listing of the child
restraints that were used to certify compliance with the US Safety
Standard =>
page 265.
The PASSENGER AIR BAG OFF light in the instrument panel tells you
when the front Advanced Airbag on the passenger side has been
turned off by the electronic control unit.
Each time you turn on the ignition, the
PASSENGER AIR BAG OFF
light will come on for a few seconds and:
• will stay on if the front passenger seat is not occupied
Controls and equip­
ment Safety first Vehicle operation
•
will stay on if there is a small child or child restraint on the front
passenger seat
• will go off if the front passenger seat is occupied by an adult as
registered by the weight-sensing mat=>
page 252, "Monitoring the
Advanced Airbag System" .
The
PASSENGER AIR BAG OFF light comes on when the control unit
detects a total weight on the front passenger seat that requires the
front airbag to be turned off.
If the total weight on the front passenger seat is more than that of
a typical 1 year-old child but less than the weight of a small adult,
the front airbag on the passenger side can deploy (the
PASSENGER
AIR BAG OFF
light does not come on). If the PASSENGER AIR BAG
OFF
light does not come on, the front airbag on the passenger side
has not been turned off by the electronic control unit and can
deploy if the control unit senses an impact that meets the condi­
tions stored in its memory.
For example, the airbag may deploy if:
• a small child that is heavier than a typical 1 year -old child is on
the front passenger seat (regardless of whether the child is in one
of the child safety seats listed=>
page 265), or
• a child who has outgrown child restraints is on the front
passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG
OFF
light comes on in the instrument cluster and stays on.
The front airbag on the passenger side may
not deploy (the
PASSENGER AIR BAG OFF light does not illuminate and stay lit) even
if a small adult or teenager, or a passenger who is not sitting upright
with their back against a non-reclined backrest with their feet on the
vehicle floor in front of the seat is on the front passenger seat
=>
page 222, "Proper seating position for the driver".
If the front passenger airbag deploys, the Federal Standard requires
the airbag to meet the "low risk" deployment criteria to reduce the risk of injury through interaction with the airbag . "Low risk" deploy­
ment occurs in those crashes that take place at lower decelerations

& WARNING (continued)
• Seat covers can prevent the Advanced Airbag System from
recognizing child restraints or occupants on the front passenger
seat and prevent the side airbag in the seat backrest from
deploying properly.
• Never use cushions, pillows, blankets or similar items on the
front passenger seat. The additional padding will prevent the
weight-sensing mat in the seat from accurately registering the
child restraint or person on the seat and prevent the Advanced
Airbag System from functioning properly .
• If you must use a child restraint on the front passenger seat
and the child restraint manufa cturer's instructions require the use
of a towel , foam cushion or something else to properly position
the child restraint, make certain that the PASSENGER AIR BAG OFF
light comes on and stays on whenever the child restraint is
installed on the front passenger seat.
• If the PASSENGER AIR BAG OFF light does not come on and stay
