seriously injured or killed by the airbag as it
unfolds. To help reduce the risk of serious per­
sonal injury:
- Passengers must always sit in an upright po­
sition and never lean against or place any
part of their body too close to the area
where the airbags are located.
- Passengers who are unbelted, out of posi­
tion or too close to the airbag can be seri­ ously injured by an airbag as it unfolds with
great force in the blink of an eye.
- Always make sure that there are at least 10 inches (25 cm) between the front pas­
senger's breastbone and the instrument panel.
- Always make sure that there are at least
4 inches (10 cm) between the front passen­
ger's knees and the lower part of the instru­
ment panel.
- 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 properly.
- For adjustable head restraints: before driv­
ing, always also adjust the head restraints
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
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 172. Special precautions apply
when installing a child seat on the front pas­
senger seat
r=> page 148.
Driving safety
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 be properly restrained whenever the ve­
hicle is 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 seat must always observe the follow­
ing :
.,. For adjustable head restraints: adjust the head
restraint so the upper edge is as even as possi­
ble with the top of your head. If that is not pos­
sible, try to adjust the head restraint so that it
is as close to this position as possible
<=>page 134 .
.,. Keep both feet flat in the footwell in front of
the rear seat .
.,. Fasten and wear safety belts properly
Qpage 143 .
.,. Make sure that children are always properly re­
strained in a child restraint that is appropriate
for their size and age
Q page 172.
A WARNING
P assengers 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 safety belts are properly posi­
tioned on the body and securely latched. By not sitting upright, a rear seat passenger in­
creases the risk of personal injury from im­ properly positioned safety belts!
- For adjustable head restraints: always ad­
just the head restraint properly so that it can give maximum protection.

Important safety instructions
App lies to vehicles: with knee airb ags
&_ WARNING
Always ma ke sure that the knee a irbag can in­
flate without interference. Objects between
yourself and the airbag can increase the r isk
of injury in an accident by interfering with the
way the airbag deploys or by being pushed in­ to you as the airbag deploys.
- No persons (chi ldren) or animals should ride
in the footwe ll in front of the passenger
seat.
If the airbag dep loys, this can result in
serious or fatal injuries.
- No objects of any kind shou ld be carried in
the footwe ll area in front of the dr iver's or
passenger's seat. Bulky objects (shopp ing
bags, for example) can hamper or prevent
proper deployment of the airbag . Small ob­

~page 130.
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 following notes to reduce
the risk of poisoning:
- Close all windows,
- Close the power roof*,
- 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, all windows,
the power roof* and the rear lid are securely
closed and locked to reduce the risk of injury
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 serious
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 hicle's seating positions.
(D Tips
- Air circulation helps to reduce window fog­
ging. Stale air escapes to the outside
through vents in the trim panel. Be sure to keep these slots free and open.
Driving safety
-The tire pressure must correspond to the
load. The tire pressure is shown on the tire
pressure label. The tire 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 ~
page 224.
' 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 136, 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 freely 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

Safety belts
Autom atic safet y belt retractors
Every safety belt is eq uipped w ith an automatic
be lt retractor on the shou lder belt. This feature
locks the belt when the be lt is pulled o ut fast,
during hard brak ing and in an accident . The belt
may also lock when you drive up or down a steep
hill or through a sharp curve. During normal driv­
ing the belt lets you move freely.
S afety belt p rete n sioner s
The safety be lts are equipped with a belt preten­
sioner that helps to t ighten the safety belt and
remove s lack when the pretensioner is activated

Safety belt posi tion.
- Safety belts offer optimum protection only
when the seatback is upright and belts are
properly positioned on the body.
- Always make sure that the rea r seat back­
rest to which t he center rear safety belt* is
attached is securely latched whenever the
rear center safety be lt is being used .
If the
backrest is not securely latched, the passen ­
ger wi ll move forward with the backrest dur­
ing sudden braking, in a sudden maneuver
and especially in a crash.
- Never attach the safety belt to the buck le
for another seat. Attaching the belt to the
wrong buckle will reduce safety be lt effec­
t iveness and can cause serious persona l in­
jury.
- A passenger who is not properly restrained can be se riously in jured by the safety belt it­
self when it moves from the stronger parts
144
of the body into critical areas like the abdo­
men.

Always remember: Even thoug h your veh icle is
eq uipped w ith an Advanced Ai rbag system, all
chi ldren, espec ia lly those 12 years and yo unger,
should always ride in the back seat properly re­
strained for their age and s ize.
A WARNING
Not using a chi ld safety seat, using the wrong
child safety seat or improperly insta lling a
child restraint increases the r isk of serious
personal injury and death .
- All veh icle occupants and especially children
must be restra ined properly whenever riding
in a vehicle. An unrestrained or improperly
restrained child could be injured by striking
the interior or by being ejected from the ve­
hicle du ring a sudden maneuver or impact.
An unrestrained or improperly restrained
child is also at greater risk of injury or death
thro ugh contact with an inflat ing airbag .
- Commercially avai lab le child safety seats
are required to comply with U.S . Fede ral Mo ­
tor Vehicle Safety Standard ( FMVSS) 213 (in
Canada CMVSS 213).
- When buying a ch ild restraint, select one
that fits your child and the vehicle.
- On ly use child restra int systems that fully
contact the flat port ion of the seat cush­
ion. The ch ild restra int must not tip o r
lean to either s ide. Audi does no t recom­
mend using child safety seats that res t on
legs o r tube -like frames. They do not pro ­
vide adequate contact with the seat.
- Always heed all legal requirements pe r­
taining to the installation and use of ch ild
safety seats and carefully follow the in-
176
str uctions provided by the manufacturer
of the seat you are using.
- Never allow children under 57 inches
(1.45 meters) to wear a norma l safety belt.
They must always be restrained by a proper
child restraint system. Otherwise, they
could sustain injuries to the abdomen and
neck areas during sudden braking maneu­
vers or accidents.
- Never let more than one child occupy a child safety seat.
- Never let babies or o lder children ride in a
veh icle wh ile sitting on the lap of another
passenger .
- Holding a child in your arms is never a sub­
stitute for a child restraint system.
- The strongest pe rson could not hold the
child with the forces that exist in an acci­
dent. The child will strike the interior of
the veh icle and can also be struck by the
passenger.
- The child and the passenger can also in­ jure each other in an accident .
- Never install rear-facing child safety seats or
infant carriers on the front passenger seat.
A child will be serious ly injured and can be
killed when the passenger airbag inflates -
even with an Advanced Airbag System .
- The inflating airbag will h it the ch ild safety
seat or infant carr ier with great force and
will smash the child safety seat and child
aga inst the backrest, center armrest, door
or roof.
- Always install rear-facing ch ild safety seats
or infant car riers on the rear sea t.
- Forwa rd-facing child safety seats instal led
on the front passenger's seat can inte rfe re
wit h the airbag when it inflates and cause
serious injury to the child. A lways install fo r­
ward-facing child sa fety seats on the rear
seat.
- If except ional circumstances req uire the use
of a fo rward-facing child restraint on the
front passenger's seat, the child's safety
and well-be ing require that the following
special precautions be taken : ..,.
