of your passengers and others . We have summar­
ized here what you need to know about safety
belts, airbags, child restraints as well as child
safety. Your safety is for us
priority number 1. Al­
ways observe the information and warnings in
this section - for your own safety as well as that
of your passengers.
The information in this section applies to all
model versions of your vehicle. Some of the fea­
tures descr ibed in this sections may be standard
equipment on some models, or may be optional
equipment on others. If you are not sure, ask
your authorized Audi dealer.
A WARNING
- Always make sure that you follow the in­
structions and heed the WARNINGS in this
Manual. It is in your interest and in the in­
terest of your passengers .
-
-Always keep the complete Owner's Litera­
ture in your Audi when you lend or sell your
vehicle so that this important information
will always be available to the driver and
passengers.
- Always keep the Owner's literature handy so
that you can find it easily if you have ques­
tions.
Safety equipment
The safety features are part of the occupant re­
straint system and work together to help reduce
the risk of injury in a wide variety of accident sit­
uations.
Your safety and the safety of your passengers
should not be left to chance. Advances in tech­
nology have made a var iety of features available
to help reduce the risk of injury in an accident.
Driving safety
The following is a list of just a few of the safety
features in your Audi:
- sophisticated safety belts for driver and all pas-
senger seat ing pos itions,
- be lt force limiters for the front seats,
- belt pretensioners for the seats,
- head restraints for each seating position,
- front airbags,
- side airbags in the front seats,
- side curtain airbags,
- specia l LATCH anchorages for child restraints,
- adjustable steering column.
These individual safety features, can work to­ gether as a system to help protect you and your
passengers in a w ide range of accidents. These
features cannot work as a system if they are not
always correctly adjusted and correctly used.
Safety is everybody's responsibility!
Important things to do before driving
Safety is everybody's job! Vehicle and occupant
safety always depends on the informed and care­
ful driver.
For your safety and the safety of your passen­
gers,
before driving always:
.. Make sure that all lights and signals are operat­
ing correctly.
.. Make sure that the tire pressure is correct.
.. Make sure that all windows are clean and afford
good visibility to the outside .
.. Secure all luggage and other items carefully
c:::>page 65.
.. Make sure that nothing can interfere with the
pedals .
.. Adjust front seat, head restraint and mirrors
correctly for your height.
.. Instruct rear seat passengers to adjust the
head restraints according to their height.
.. Make sure to use the right child restraint cor­
rectly to protect children
c:::> page 158, Child
safety .
.. Sit properly in your seat and make sure that
your passengers do the same
c:::> page 59, Seats
and storage.

Driving safety
-Each passenger must always sit on a seat of
their own and properly fasten and wear the
safety belt belonging to that seat.
- Before driving, always adjust the front pas­
senger seat and head restraint properly.
- Always keep your feet on the floor in front
of the seat. Never rest them on the seat in-
'
strument panel, out of the window, etc. The
airbag system and safety belt will not be
able to protect you properly and can even in­
crease the risk of injury in a crash.
- Never drive with the backrest reclined or
tilted far back! The farther the backrests are
t il ted 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 safety
seats ¢
page 158. Special precaut ions ap­
ply when installing a child safety seat on the
front passenger seat¢
page 138.
Proper seating positions for passengers in
rear seats
Rear seat passengers must sit upright with both
feet on the floor consistent with their physical
size and b e properly restrained wh enever the ve­
hicle i s in use.
To reduce the risk of injury caused by an incorrect
seating position in the event of a sudden braking
maneuver or an accident, your passengers on the
rear bench sea t must always observe the follow­
ing:
... Make sure that the seatback is securely latched
in the upright position ¢
page 69.
... If there is a passenger on the rear center seat­
ing position, slide the center head restra int up­
ward at least to the next notch .
... Keep both feet flat in the footwell in front of
the rear seat.
.,. Fasten and wear safety be lts properly
¢ page 133.
... Make sure that children are always properly re­
strained in a child restraint that is appropriate
for their size and age¢
page 158.
124
A WARNING
Passengers who are improperly seated on the
rear seat can be seriously injured in a crash.
- Each passenger must always sit on a seat of
their own and properly fasten and wear the
safety belt belonging to that seat .
- Safety belts only offer maximum protection
when the seatback is securely latched in the
upright position and the safety belts are
properly positioned on the body . By not sit­
ting upr ight, a rear seat passenger increases
the risk of personal injury from improperly
positioned safety belts!
-Always adjust the head restraint properly so
that it can give maximum protection.
Proper adjustment of head restraints
Applies to vehicles: with adjustable head restra ints
Correctly adjusted head restraints are an impor­
tant part of your vehicle's occupant restraint sys­
tem and can help to reduce the risk of injuries in
accident situations.
Fig. 139 He ad restraint : viewe d from t he front
The head restraints must be correctly adjusted to
achieve the best protection .
... Adjust the head restraints so the upper edge is
as even as possible with the top of your head . If
that is not possible, try to adjust the head re­
straint so that it is as close to this position as
possible ¢
fig. 139 .
... If there is a passenger on the rear center seat­
ing position, slide the center head restraint up­
ward at least to the next notch .
Adjusting head restraints¢

0 ::..:: co ,...., & WARNING
All seats are equipped with head restraints. Driving without head restraints or with head
restraints that are not properly adjusted in­
creases the risk of serious or fatal neck injury
dramatically. To help reduce the risk of injury:
-Always drive with the head restraints in
place and properly adjusted.
- Every person in the vehicle must have a
properly adjusted head restraint.
- Always make sure each person in the vehicle
properly adjusts their head restraint. Adjust
the head restraints so the upper edge is as
even as possible with the top of your head.
If that is not possible, try to adjust the head
restraint so that it is as close to this position
as possible.
- Never attempt to adjust head restraint
whi le driving. If you have driven off and
must adjust the driver headrest for any rea­
son, first stop the vehicle safely before at­
tempting to adjust the head restra int.
- Children must always be properly restrained
in a child restraint that is appropriate for
their age and size
q page 158.
Examples of improper seating positions
-
The occupant restraint system con only reduce
the risk of injury if vehicle occupants ore properly
seated.
Improper seating positions can cause serious in­
jury or death. Safety belts can only work when
they are properly positioned on the body. Im­
proper seating positions reduce the effectiveness
of safety belts and will even increase the risk of
injury and death by moving the safety belt to crit­
ical 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 occu­
pants and especia lly for children. Therefore:
.. Never allow anyone to assume an incorrect
seating position when the vehicle is being used
q& ,
Driving safety
The following bulletins list only some sample po ­
sitions that will increase the risk of serious injury
and death. Our hope is that these 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
A 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.
Pedal area
Pedals
The pedals must always be free to move and
must never be interfered with by a floor mot or
any other object.
Make sure that all pedals move freely w ithout in­
terference and that nothing prevents them from
returning to their original positions .
Only use floor mats that leave the pedal area free
and can be secured with floor mat fasteners .
If a brake circuit fails, increased brake pedal trav-
el is required to bring the vehicle to a fu ll stop . .,._
125

Driving safety
_& WARNING
Pedals that cannot move freely can cause loss
of vehicle control and increase the risk of seri·
ous injury .
- Never place any objects in the driver's foot­
well. An object could get into the pedal area
and interfere with pedal function . In case of
sudden braking or an accident, you would
not be able to brake or accelerate!
-Always make sure that nothing can fall or
move into the driver 's footwell.
Floor mats on the driver side
Always use floor mats that can be securely at­
tached to the floor mat fasteners and do not in­
terfere wi th the free movement of the pedals .
.,. Make sure that the floor mats are properly se­
cured and cannot
mov e and interfere with th e
pedals
c:> ,& .
Use only floor mats that leave the pedal area un­
obstructed and that are firmly secured so that
they cannot slip out of position. You can obtain
suitable floor mats from your authori zed Audi
dealer .
Floor mat fasteners are installed in your Audi.
Floor mats used in your vehicle must be attached
to these fasteners. Properly securing the floor
mats will prevent them from sliding into posi­
tions that could interfere with the pedals or im­
pair safe operation of your vehicle in other ways.
A WARNING
Pedals that cannot move freely can result in a
loss of vehicle control and increase the risk of
serious personal injury .
- Always make sure that floor mats are prop­
erly secured.
- 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 ped­ als or the ability to control the vehicle.
- Never place or install floor mats or other
floor coverings on top of already installed
126
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 footwell while the vehicle is
moving. Objects can become trapped under
the brake pedal and accelerator pedal caus­ ing a loss of vehicle control.
Storing cargo correctly
Loading the luggage compartment
All luggage and other objects must be properly stowed ond secured in the luggage compart­
ment .
Fig. 140 Safe load positioning : place heavy ob jects as low
and as far forward as poss ib le.
Loose items in the luggage compartment can
shift suddenly, changing vehicle handling charac­
teristics. Loose items can also increase the risk of
serious personal injury in a sudden vehicle ma­
neuver or in a collision .
.,. Distribute the load evenly in the luggage com­
partment.
.,. Always place and properly secure heavy items in
the luggage compartment as low and as far for­
ward as possible
c:> fig. 140 .
.,. Secure the load with the cargo net* or with
non-elastic straps secured to the tie -downs*
c:> page 71 c:>page 72.
.,. Make sure that the rear seatback is securely
latched in place.

..... N
0 ::..:: co ..... ..... A WARNING
Improperly stored luggage or other 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 secure objects in the luggage com­
partment using the tie-down eyelets and
suitable straps.
A WARNING
Heavy loads will influence the way your vehi­
cle 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 compartment 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. Exceed ing permissible weight
standards can cause the veh icle to slide and
hand le differently.
- Please observe information on safe driving
qpage 121.
A 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 into the luggage area be­
cause the rear lid cannot be fully closed.
- If you absolutely must drive with the rear lid
open, observe the fo llowing notes to reduce
the risk of poisoning:
- Close all windows,
- Close the sunroof,
Driving safety
-Open all air outlets in the instrument pan­
el,
- Switch off the air recirculation
,
- Set the fresh air fan to the highest speed .
A WARNING
=
Always make sure that the doors, a ll win-
dows, the sunroof and the rear lid are secure­
ly closed and locked to reduce the risk of in­
jury when the vehicle is not being used.
- After closing the rear lid, always make sure
that it is properly closed and locked .
- Never leave your vehicle unattended espe­
cially with the rear lid left open . A child
could crawl into the vehicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out . Be­
ing trapped in a vehicle can lead to ser ious
personal injury.
- Never let children play in or around the vehi­ cle .
- Never let passengers ride in the luggage
compartment . Vehicle occupants must al­
ways be properly restrained in one of the ve­
h icle 's seat ing positions.
(D Tips
-Air circulation helps to reduce window fog­
ging . Stale air escapes to the outs ide
through vents in the tr im panel. Be sure to
keep these slots free and open.
- The tire pressure must correspond to the
load. The t ire pressure is shown on the tire
pressure label. The tir e pressure label is lo­
cated on the driver's side B-pillar . The tire
pressure label lists the recommended 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 man­
ufactured. For recommended tire pressures
for normal load conditions, please see chap­
ter

Driving sa fe ty
Tie-downs
Applies to vehicles: with 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 126, 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 ser ious in­
jury. Items in the veh icle possess energy which
vary with vehicle speed and the weight of the
item . Veh icle speed is the most s ignificant facto r.
For examp le, in a frontal collision at a speed of
30 mph (48 km/h), the forces act ing on a 10-lb
(4 .5 kg) object are about 20 times the normal
weight of the item. Th is means that the weight
of the item would suddenly be about
200 lbs . (90 kg). You can imagine the injuries
that a 200 lbs. (9 0 kg) item flying free ly through
the passenger compartment could cause in a co l­
lision like this.
/1. WARNING
Weak, damaged or improper straps used to secure items to tie-downs can fail d uring hard
brak ing or in a collision 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 forwa rd as dan­
gerous missiles .
- When the rear seat backrest is folded down, always use suitab le mounting straps and
prope rly secure items to the tie-dow ns in
the luggage compartmen t to help p reve nt
items from f lying forwa rd as dangerous
missiles into the passenger compartment .
- Never a ttach a child safe ty seat tether strap
to a tie-down.
