Loose items in the luggage compartment can
shift s udden ly, changing vehicle handling charac
ter istics. Loose items can also increase the risk of
serious personal in jury in a sudden vehicle
ma
neuver or in a coll is ion.

A WARNING
Improperly stored luggage or othe r items can
fly through the vehicle causing serious per
sonal 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 compart
ment.
- Always sec ure objects in the luggage com
partment using the tie-down eyelets and
s u itable straps.
A WARNING
Heavy loads will influence the way your vehi
cle handles. To he lp reduce the r isk of a loss
of contro l leading to serious pe rsonal i njury:
- Always keep in mind when transporting heavy objects, that a change i n the center of
grav ity can also cause changes in vehicle
hand ling:
- Always distr ibute the load as even ly as
possible.
- Place heavy objects as far forward in the
luggage compartment as poss ible.
- Never exceed the Gross Axle Weight Rating
o r the Gross Vehicle Weight Rating specified
on the safety compliance sticker on the driv
er's side B-pillar respective ly on the front
end of the driver's door. Exceeding permissi
ble weight standards can cause the veh icle
to slide and handle differently .

-Please observe info rmation on safe driving
¢page 254.
A WARNING
To he lp prevent po isonous 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 dr ive with the rear lid
open, observe the following notes to reduce
the risk of poisoning :
- C lose all windows,
- Close the s unroof*,
- Open all a ir outlets in the instrument pan-
el,
- Switc h off the air reci rculat ion,
- Set the fresh air fan to the highest speed.
A WARNING
-
Always make sure that the doo rs, all win
dows, the sunroof * an d the rear lid are se
curely closed and locked to red uce the risk of
i n jury when the veh icle is not being used.
- After closing the rear lid, always make sure
that it is properly closed and locked.
- Never leave your ve hicle unattended espe
cially with the rear lid left open. A child
co uld crawl into the vehicle th rough the lug
g age com partment an d close the rea r lid
be
coming tr apped and unab le to ge t out . Be
ing trapped in a vehicle can lead to ser ious
pe rsonal i nju ry.
- Never let c hild ren p lay in or around the vehi
cle.
- Never let passengers ride in the luggage
compa rtment. Vehicle occupants mus t
al
ways be p roperly restrained in one of the ve
hicle's seat ing pos itions.
(D Tips
- Air circul ation helps to reduce w indow fog
ging . Stale ai r escapes to the o uts ide
t h roug h vents in the trim panel. Be sure to
keep these slots free and open.

-The tire pressure must correspond to the
load. The tire pressure label lists the recom
mended 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 manufactured. For recommend
ed tire pressures for normal load condi
tions, please see chapter
c:> page 345.
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
c:> page 259, 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 -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
that a 200 lbs. (90 kg) item flying free ly through
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 braking or in a collision and cause serious per
sonal injury.
- Always use suitable 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 .
-When the rear seat backrest is folded down,
always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help prevent
items from flying forward as dangerous
missiles into the passenger compartment .
-
Driving safety
-Never attach a child safety seat tether strap
to a tie-down.

Safety belts
General information
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety belts 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 single most effective
means available to reduce the risk of serious
injury and death in automobile accidents.
For your protection and that of your passen
gers, always correctly wear safety belts
when the vehicle is moving.
- Pregnant women, injured, o r physically
im
paired 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 has a total of five seating positions:
two in the front and three in the rear. Each seat
ing position has a safety belt.
A WARNING
Not wearing safety belts or wearing them im
properly increases the risk of serious personal
injury and death.
- Never strap more than one person, includ
ing small children, into any belt.
It is espe
cially dangerous to place a safety belt over a
~ child sitting on your lap.
~ -Never let mo re people ride in the vehicle
:::l than there are safety belts available. 0 0

Safety belts
Why use safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for peo
ple riding in vehicles .
Fig. 228 Unbelted occupants in a veh icle headi ng fo r a wall
Fig. 229 T he vehicle c rashes into the wall
The physical principles are simple. Both the vehi
cle and the passengers possess energy which var ies w ith vehicle speed and body weight . Engi
neers call this energy "k inetic 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 passengers of this vehicle are not us
ing safety
belts ~ fig. 228, they will keep moving
at the same speed the vehicle was moving just
before the crash, unti l something stops them -
here, the
wall ~ fig. 229.
The same principles apply to people sitting in a
vehicle that is involved in a frontal collision . Even
at c ity speeds of 20 to 30 mph (30 to 50 km/h),
the forces acting on the body can reach one ton
264 (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 in
jured or killed . Always wear your safety belts!
Fig. 230 A drive r not wea ring a safety belt is vio len tly
t hrow n fo rward
Fig. 231 A rear passe nge r not wear ing a sa fety belt will f ly
forward an d str ike the driver
Unbelted occupants are not able to res ist the tre
mendous forces of impact by holding tight or
bracing themselves. Without the benefit of safe
ty restraint systems, the unrestra ined occupant
will slam violently into the steering wheel, in
strument panel, windshield, or whatever e lse is
in the
way ~ fig. 230. T his impact with the vehi
cle interior has all the energy they had just be-
fore the crash.
liJJ,-
Page 266 of 403
Never rely on airbags alone for protection. Even
when they deploy, airbags provide on ly additional
protection. Airbags are not supposed to dep loy in
all kinds of accidents. A lthough your Audi is
equipped with 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, that airbags will deploy only
once and that your safety belts are always there
to offer protect ion in those accidents in w hich
a ir bags are not supposed to deploy or when they
have already deployed. Unbelted occupants can
also be thrown o ut of the vehicle where even
more severe or fatal injur ies can occur.
It is also important for the rear passengers to
wear safety belts correctly . Unbelted passengers
in the rear seats endanger not only themse lves
but also the driver and other passengers
¢ fig. 231. 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. 232 Driver is correct ly restra ined in a sudden b rak ing
maneuver
Safety belts used properly can make a big differ
ence. Safety belts he lp to keep passengers in
thei r seats, gradually reduce energy leve ls ap
plied to the body in an acciden t, and help prevent
the uncontrolled movement that can cause seri
ous injuries. In addition, safety belts reduce the
danger of being thrown out of the vehicle.
Safety belts
Safety belts attach passengers to the car and give
them the benefit of being slowed down more
gently or "softly" through the
"give" i n the safety
belts, crush zones and other safety features engi
neered into today's vehicles. By "absorbing" the
kinetic ene rgy over a longer period of time, the
safety belts make the forces on the body more
"tolerab le" and less likely to ca use injury .
Although these examples are based on a frontal collision, safety be lts can also substantially re
duce the r isk of injury in other k inds of crashes.
So, whether you're on a long trip or just go ing to
the corner store, always buckle up and make sure
others do, too. Acciden t statist ics show that vehi
cle 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 supp lemental airbags to do their job in a col
lision. For this reason, wearing a safety belt is le
gally required in most count ries including much
of the United States and Canada .
Although your Aud i 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 act i
vated in all frontal collisions, in side and rear col
lisions , in rollovers or in cases where there is not
enough deceleration through impact to the front
of the vehicle. The same goes for the other air bag
systems in your Audi . So, always wear your safety
belt and make sure everybody in your vehicle is
properly restrained!
Important safety instructions about safety
belts
Safety belts must always be correctly positioned
across the strongest bones of your body.
.,. Always wear safety belts as illustrated and de
scribed in this chapter.
.,. Make sure that your safety belts are always
ready for use and are not damaged.

_& 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-
266
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 , disassemble, 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 reel¢

l ocks the belt when the belt is p ulled out fast,
during hard braking and in an accident. The belt may also lock when you drive up or down a steep
h ill or through a sharp curve. During normal driv
ing the belt lets you move freely .
Safety be lt pret en sioner s
The safety belts are equipped with a belt preten
sioner that helps to tighten the safety belt and
remove slack when the pretensioner is activated
