2018 AUDI A8 Owners Manual

Tie-downs
The luggage compartment is equipped with four
tie-downs to secure luggage and other items .
Use the tie-downs to secure your cargo properly
¢ page 213, Loading the luggage compartment.
In a collision, the laws of physics mean that even
sma ller items that are loose in the vehicle will
become heavy missiles that can cause ser ious in­
jury . Items in the ve hicle possess energy which
vary with vehicle speed and the weight of the item . Veh icle speed is the most s ignif ica nt factor .
For example, in a frontal collision at a speed of
30 mph (48 km/h), the forces act ing o n a 10-lb
(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
t hat a 200 lbs. (9 0 kg) item flying freely throug h
the passenger compartment could cause in a col­
lision like this.
A WARNING
Weak, damaged or improper straps used to
secure items to tie-downs can fail during hard
brak ing or in a col lision and cause serious per­
sonal injury .
- Always use suitab le mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help prevent
items from shifting or flying forward as dan­
gerous missiles .
- Never attach a child safety seat tether strap
to a tie-down .

General information
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety be lts are neces­
sary, how they work and how to adjust and wear
them correctly.
~ Read all the information that follows and heed
all of the instructions and WARNINGS.
A WARNING
Not wearing safety belts or wearing them im­
properly increases the risk of serious personal
injury and death.
- Safety belts are the s ingle most effective
means ava ilable to reduce the risk of serious
injury and death in automobi le accidents.
For your protection and that of your passen­
gers, always co rrect ly wea r safety be lts
w hen the veh icle is mov ing.
- Pregnant wome n, in ju red, o r physically im­
paired persons mus t also use safety be lts.
Lik e al l vehicle oc cupan ts, they are mo re
li kely to be serio usly injured i f th ey do no t
wear safety be lts . The best way to protect a
fetus is to protect the mothe r -throug hout
the ent ire pregnancy.
Number of seats
Your Aud i has a total of five seating positions:
two in the front and three in t he rear. In some
veh icles, there are four seat ing positions: two in
the fro nt and two in the rear . Each seati ng posi­
tion has a safety belt.
A WARNING
N ot we aring safety bel ts or wear ing them im­
pro perly in cre ases the risk of ser io us pe rsonal
inju ry and dea th.
- Never st rap more th an one pe rso n, includ ­

Safe ty belts
-Failure to pay attention to the warning light
that come on, could lead to personal injury.
Why use safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for peo­
ple riding in vehicles.
F ig. 220 Unbe lted occupants in a vehicle heading for a wall
Fig . 221 The veh icle crashes into the wall
The physical principles are simple . Both the vehi­
cle and the passengers possess energy which var­
ies with vehicle speed and body weight. Engi­
neers call this energy "kinet ic energy."
The higher the speed of the vehicle and the greater the vehicle 's we ight, the more energy
that has to be "absorbed" in the crash.
Vehicle speed is the most significant fac tor. If
the speed doubles from 15 to 30 mph (25 to SO
km/h), the energy increases 4 times!
Because the passengers of th is veh icle are not us­
ing safety
belts<=> fig. 220, they will keep mov ing
at the same speed the ve hicle was moving just
before the crash, u nti l something stops them -
here, the wall<=>
fig. 221.
220
The same principles apply to people s itting in a
vehicle that is involved in a fronta l 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 a lso not
attached to their vehicle. In a frontal coll is ion
they will also keep mov ing forward at the speed
their vehicle was travelling just befo re the crash.
Of course, the laws of physics don't just apply to
frontal collisions, they determine what happens
i n a ll kinds of accide nts and co lli sions.
What happens to occupants not wearing
safety belts?
In crashes unbelted occupants cannot stop
themselves from flying forward and being in­
jured or killed. Always wear your safety belts!
Fig. 222 A driver not wearing a safety belt is violently
thrown forward
F ig. 223 A rear passenger not wearing a safety belt will fly
forwa rd a nd strike the driver
Unbelted occ upants are not ab le to res ist the tre­
mendous forces of impact by holding tight or
braci ng themselves . Without the benefit of safe ­
ty restraint systems, the unrestra ined occupant
will slam violently into the steering wheel,

in the way ¢
fig. 222. This impact w ith the vehi­
cle interior has all the energy they had just be­
fore the crash.
Never rely on airbags alone fo r protection . Even
when they deploy, airbags provide on ly additiona l
protection. Airbags are not supposed to dep loy in
all kinds of accidents. A lthough your Audi is
equ ipped w ith airbags, all vehicle occupants, in­
cluding the dr iver , must wear safety belts cor ­
rectly in order to minimize the risk of severe in­
jury or death in a crash .
Remember too, tha t airbags will deploy only
once and that your safety belts are always there
to offer protec tion in those acc idents in w hich
airbags are not supposed to deploy or when they
have a lready deployed. Unbel ted occupants can
also be thrown o ut of the vehi cle where even
more severe or fatal injur ies can occur .
It is also important for the rear passenge rs to
wear s afety bel ts corre ctly . U nbel ted passengers
in the re ar seats endanger no t onl y themse lves
but also the driver and ot her passengers
¢ fig . 223. In a fronta l collision they will be
thrown forward violently, where they can hit and
in jure the driver and/or front seat passenger .
Safety belts protect
People think it's possible to use the hands to
brac e the body in a minor collision . It 's simply
not true!
F ig . 2 24 Drive r is correctly rest ra ined in a sudde n brak ing
m aneuver
Safety belts used properly can make a big d iffer­
ence. Safety belts he lp to keep passengers in
their seats, gradually reduce energy leve ls ap-
Safet y bel ts
plied to the bo dy i n an accident, and help prevent
t h e uncontrolled movement that can cause seri­
ous injuries. In addition, safety belts reduce the
danger of be ing th rown out of the vehicle.
Safety be lts attach passengers to the car and g ive
them the benefit of be ing s lowed down more
gently or "soft ly" th rough the "give" in the safety
belts, crush zones and other safety features engi­
neered into today's vehicles. By "absorbing" the
k inetic ene rgy over a longer period of t ime, the
sa fe ty belts make the fo rces on the body more
"tolerab le " and less likely to ca use in jury.
Although these examples are based on a frontal collision, safety be lts can also substa ntia lly re ­
duce the r is k of injury in ot her k inds of crashes .
So, whethe r you're on a long tr ip or just go ing to
t h e cor ner store , a lways b uck le up and make sure
othe rs do, too. A cciden t st atis tic s show tha t ve hi­
cl e occupan ts properly wea ring safety bel ts have
a lower risk of be ing injured and a muc h better
chance of surviving an acci dent . Properly using
sa fety belts also great ly increases the ability of
the supp lemental airbags to do their job in a col­
lis ion. For this reason, wearing a safety belt is le­
gally required in most count ries includ ing much
of the United States and Canada .
Although your Aud i is equipped with airb ags, you
still have to wear the safety belts provided. Front airbags, for example, are activated only in some
frontal collisions. The front airbags a re not ac ti­
vated in a ll frontal collisions , in side and rear co l­
li sio ns, in roll overs or i n cases where the re is not
eno ugh deceleration throug h impact to the front
of the veh icle. The same goes for the other a irbag
systems in your Audi . So, always wear your safety
belt and make sure everybody in your vehicle is
properly rest rained !
Important safety instructions about safety
belts
Safe ty belts must always be correctly posi tioned
across the strongest bones of your body.
.. Always wear safety belts as illustrated and de­
scribed in this chapter .
.. Make sure that your safety be lts are always
ready for use and are not damaged.

Safety belts
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.
-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-
222
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 , d isassemble, or try
to repair the safety belts yourself .
-Always keep the belts clean. Dirty belts may not work properly and can impair the func­
tion of the inertia
