-Never place or install floor mats or other
floor coverings on top of already installed
floor mats. Additional floor mats and other
coverings w ill reduce the size of the pedal
area and inte rfere 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 veh icle is
moving . Objects can become trapped under
the brake peda l and accelerator pedal caus­
ing a loss of veh icle control.
Storing cargo correctly
Loading the luggage compartment
All luggage and other objects must be properly
stowed and secured in the luggage compart­
ment.
F ig. 22 4 Safe load position ing: place heavy objects as low
and as
far forward as possible.
L oose items in the luggage compartment can
shift sudden ly, 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 coll ision.
• Distribute the load evenly in the luggage com­
partment.
• Always place and properly secure heavy items in
the luggage compartment as far forward as
poss ib le.
• Secure luggage using the tie-downs provided
<:;> page 66 .
• Make sure that the rear seatbac k is securely
latched in place.
Dr iving safety
A WARNING
-
Improperly stored luggage or other items can
fly through the vehicle caus ing serious per­
sonal injury in the event of hard brak ing or an
accident. To help reduce the risk of serio us
pe rsonal injury:
- Always put objects, for example, l uggage or
other heavy items in the luggage compa rt­
men t.
- Always secure objects in the luggage com­
partment using the tie-down hooks and
suitable st raps.
A WARNING
H eavy loads will influen ce the way your veh i­
cle hand les. To help reduce the risk of a loss
of cont rol leading to serious personal injury:
- Always keep in m ind when transpo rting
heavy objects, that a change in the center of
gravity can also cause changes in vehicle
handling:
- Always distribute the load as evenly as
poss ible.
- Place heavy objects as far fo rwa rd in the
lu ggage compartment as possible.
- Never exceed the Gross Ax le Weight Rating
or the Gross Ve hicle Weight Rating specified
on the safety compliance s ticker on the left
door jamb. Exceeding permissible we ight
s tanda rds can cause the vehicle to slide and
h a ndle differen tly.
- Pl ease observe info rmat ion on safe driv ing
¢page 247.
A WARNING
To he lp prevent poiso nous ex ha ust gas from
being drawn into the vehicle, always keep the
r ear lid closed while driving .
- Never transport ob jects larger t han those
f itting completely into the luggage area be ­
cause the rear lid cannot be f ully closed .
- If you absolutely m ust dr ive wi th the rear lid
open, observe the following notes to reduce
the risk of poisoning:
- Close all windows,
- Close the power roof*,
253

Driving safety
-Close the power top*,
- Open all air outlets in the instrument pan-
el,
- Switch off the air recirculation,
- Set the fresh air fan to the highest speed.
.&, WARNING
-
Always make sure that the doors, all win­
dows, the power roof*, the power top* 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.
- 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
c:> page 336.

· 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 253, 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 sudden ly 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.
.&, 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.
- Never attach a child safety seat tether strap
to a tie-down.

Although your Audi is equipped with airbags, you
still hav e to wear the safety belts provided. Front
airbags, for example, are activated only in some
frontal collisions. The front airbags are not acti­
vated in all frontal collisions, in side and rear col­ lisions, in roll overs or in cases where there is not
enough deceleration through impact to the front
of the vehicle . The same goes for the other airbag
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 ar e not damag ed.
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
Safety belts
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
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

Autom ati c safet y belt retr actors
Every safety belt is equipped with an automatic
belt retractor on the shoulder belt . This feature
locks the belt when the belt is pulled out fast,
during hard braking and in an accident . The belt
may a lso lock when you drive up or down a steep
h ill or th rough a sharp curve. Dur ing no rmal driv­
ing the bel t lets you move freely.
Safe ty belt pret ension ers
The safety belts are equipped with a belt preten­
sioner that helps to t ighten the safety belt and

the important information about thi s feature
¢ page 303.
A WARNING
Improperly positioned safety belts can cause
serious injury in an accident ¢
page 263,
Safety belt position .
- Safety belts offer optimum protection only
when the seatback is upright and belts are properly posit ioned on the body .
- Always make sure that the rear seat back ­
rest to which the center rear safety belt* is
attached is securely latched whenever the
rear center safety belt is being used.
If the
backrest is not sec urely latched, the passen ­
ger will move forward with the back rest du r­
ing sudden braking, in a sudden maneuver
and especia lly in a crash.
- Never attach the safety belt to the buckle for another seat. Attaching the belt to the
wrong buckle will reduce safety be lt effec­
tiveness and can cause serio us personal in­
jury.
-A passenger who is not properly restrained
can be seriously injured by the safety belt it­
self when it moves from the stronger parts
of the body into critical areas like the abdo­
men .
-Always lock the convertible locking retractor
when you are securing a c hild safety seat in

rear seat positions if the
PASSENGER AIR
BAG OFF
light does not stay on.
- Have the airbag system inspected by your
authorized Audi dealer immediately.
(D Tips
The child safety seats listed in categories A to
C have been statically tested by Audi only for
the Advanced Airbag function.
Important safety instructions for using
child safety seats
Correct use of child safety seats substantially re­
duces the risk of injury in an accident!
As the driver, you are responsible for the safety
of everybody in the vehicle, especially children:
.,. Always use the right child safety seat for each
child and always use it properly
c::> page 298.
.,. Always carefully follow the child safety seat
manufacturer's instructions on how to route
the safety belt properly through the child safe­
ty seat .
.,. When using the vehicle safety belt to install a
child safety seat , you must first activate the
convertible locking retractor on the safety belt
to prevent the child safety seat from moving
c::> page 303.
.,. Push the child safety seat down with your full
weight to get the safety belt really tight so that
the seat cannot move forward or sideways
more than one inch (2.5 cm).
.,. Secure unused safety belts on the rear seat
c::> page 298 .
Always remember: Even though your vehicle is
equipped with an Advanced Airbag system, all
children, especially those 12 years and younger,
should always ride in the back seat properly re­
strained for their age and size.
.&, WARNING
Not using a child safety seat, using the wrong
child safety seat or improperly installing a
296
child restraint increases the risk of serious
personal injury and death.
- All vehicle occupants and especially children
must be restrained 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 during a sudden maneuver or impact .
An unrestrained or improperly restrained
child is also at greater risk of injury or death
through contact with an inflating airbag.
- Commercially available child safety seats
are required to comply with U.S. Federal
Motor Vehicle Safety Standard (FMVSS) 213
(in Canada CMVSS 213).
- When buying a child restraint, select one
that fits your child and the vehicle .
- Only use child restraint systems that fully
contact the flat portion of the seat cush­ ion. The child restraint must not tip or
lean to either side. Audi does not recom­
mend using child safety seats that rest on
legs or tube-like frames. They do not pro­
vide adequate contact with the seat.
- Always heed all legal requirements per­
taining to the installation and use of child
safety seats and carefully follow the in­
structions provided by the manufacturer
of the seat you are using.
- Never allow children under 57 inches
(1.45 meters) to wear a normal 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 older children ride in a
vehicle while 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 person could not hold the
child with the forces that exist in an acci­
dent. The child will strike the interior of
the vehicle and can also be struck by the
passenger.

Child safety
-Take the child restraint off the front passen­ger seat and install it proper ly at one of the
rear seat positions if the

A toddler or child is usually too large for an in­
fant restraint if it is more than one year old and
weighs more than 20 lbs . (9 kg).
300
Toddlers and children who are older than one
year up to about 4 years old and weigh more than
20 lbs (9 kg) up to 40 lbs. (18 kg) must always be
properly restrained in a child safety seat certified
for their size and weight
c> fig. 254 and
¢ fig. 255.
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-fac ing child safety seat .
It is a
very dangerous place for an infant or a larger
ch ild in a rearward-facing seat .
.&_ WARNING
Not using a child safety seat, us ing the wrong
ch ild safety seat or imprope rly i nstalling a
chi ld restraint increases the risk of serious
personal injury and death in a collision or oth ­
er emergency situation.
-Ch ildren on the front seat of any car, even
with Advanced Airbags, can be seriously in­
jured or even killed when an
airbag inflates .
A child in a rearward-fac ing ch ild safety seat
installed on the front passenger seat will be
serious ly injured and can be killed if the
front airbag inflates -even with an Ad­
vanced Airbag System .
-The inflating airbag will h it the chi ld safety
seat or infant carr ier with great force and
w ill smash the child safety seat and child
aga inst the backrest, center a rm rest, doo r
or roof.
-Always i nstall rear-fac ing ch ild safety seats
on the rear seat.
-I f you must install a rearwa rd facing child
safety seat on the front passenger seat be ­
cause of exceptional circ umstan ces a nd the
PASSENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rear-facing child safety seat in a rear seating position and have the airbag system
inspected by your Audi dealer .
- The rear side of the ch ild safety seat should
be positioned as close as possible to the
backrest on the veh icle seat.

Child safety
Booster seats and safety belts
Properly used booster seats can help protect
children weighing between about 40 lbs . and 80
lbs. (18 kg and 36 kg) who are less than 4
ft. 9
in. (57 inches/1.45 meters) tall .
Fig. 256 Rear seat: child properly restrained in a booster
seat
The vehicle's safety belts alone will not fit most
children until they are at least 4
ft. 9 in. (57 in­
ches/1.45 meters) tall and weigh about 80 lbs.
(36 kg). Booster seats raise these children up so
that the safety belt will pass properly
over the
stronger parts of their bodies and the safety belt
can help protect them in a crash.
• Do not use the convertible locking retractor
when using the vehicle's safety belt to restrain
a child on a booster seat.
• The shoulder belt must lie as close to the cen­
ter of the child's collar bone as possible and
must lie flat and snug on the upper body. It
must never lie across the throat or neck. The
lap belt must lie across the pelvis and never
across the stomach or abdomen . Make sure the
belt lies flat and snug. Pull on the belt to tight­
en if necessary .
• Applies to: vehicles with safety be lt height ad­
justment: If you must transport an older child
in a booster seat on the front passenger seat,
you can use the safety belt height adjustment
to help adjust the shoulder portion properly.
• Secure unused safety belts on the rear seat
qpage298 .
Children up to at least 8 years old (over 40 lbs or
18 kg) are best protected in child safety seats de­
signed for their age and weight. Experts say that
the skeletal structure, particularly the pelvis, of
302
these children is not fully developed, and they
must not use the vehicle safety belts without a
suitable child restraint.
It is usually best to put these children in appro­
priate booster seats. Be sure the booster seat
meets all applicable safety standards.
Booster seats raise the seating position of the
child and reposition both the lap and shoulder
parts of the safety belt so that they pass across
the child 's body in the right places. The routing of
the belt over the child's body is very important
for the child's protection, whether or not a boos­
