Loose items in the luggage compartment can
shift suddenly, chang ing vehicle handling charac­
ter istics . Loose items can also increase the risk of
serio us personal inj ury in a sudden vehicle ma­
ne uver 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 ible.
• Secure luggage using the tie-downs provided
¢ page 63.
• Make sure that the rear seatback is securely
latched in place .
A WARNING
Improperly stored luggage or other items can
fly through the vehicle causing serio us per­
sonal injury in the event of hard braking or an
accident . To help reduce the risk of serious
personal injury:
- Always put objects, fo r example, luggage o r
other heavy items in the luggage compart­ ment.
- Always sec ure objects in the luggage com­
partment using the tie-down hooks and
s u itable straps .
Driving safety
A WARNING
Heavy loads will influence the way your vehi­
cle handles. To help reduce the risk of a loss
of control lead ing to serious personal injury:
- Always keep in m ind when transport ing
heavy objects, that a change in the center of
gravity can a lso 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 Ax le Weight Rating
or the G ross Vehicle Weight Rating specified
on the safety compliance sticker on the left
door jamb. Exceeding permissible we ight
standards can cause the vehicle to slide and handle differently.
- Please observe information on safe driving
¢page 249 .
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 fu lly closed.
- If you absolutely must dr ive with the rear lid
open, observe the following notes to reduce
the risk of poisoning:
- Close all windows,
- Close the power roof*,
- Close the power top*,
- Open alt a ir outlets i n the instrument pan-
el,
- Switch off the air rec irculat ion ,
- Set the fresh air fan to the highest speed.
A 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
r educe the risk of injury when the vehicle is
n ot being used.

- After closing the rear lid, a lways make sure
that it is properly closed and locked.
- Never leave yo ur vehicle unattended espe­
c ia lly w ith the rear lid left open. A ch ild
could crawl into the ve hicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out . Be­
ing t rapped in a veh icle can lead to se rious
persona l injury.
- Never let children play in or around the veh i­
cle .
- Never let passengers ride in the luggage
compartment. Ve hicle occupants m ust al­
ways be prope rly rest ra ined in one of the ve­
hicle's seating posi tions.
(D Tips
- A ir c irculat io n helps to reduce window fog­
g ing . Stale air escapes to the outside
th rough vents i n the t rim panel. Be s ure to
k eep these slots free and open.
- The t ire pressu re must correspond to the
l oad. The tire p ressure is shown on the tire
p ressure labe l. Th e tire pressu re labe l is lo ­
ca ted on t he driver 's s ide B-p illar. The tir e
p ressure labe l lists the recommended cold
tire inflation pressures for the vehicle at its max imum capacity weig ht and the t ires t hat
were on your vehicle at the t ime it was man­
ufactured. For recommended tire pressures
for normal load cond itions, please see chap­
ter
¢ page 341.
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 proper ly
¢ page 255, Loading the luggage compartment.
In a col lision, the laws of p hysics 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 t he ve hicle possess energy which
vary with vehicle speed and the weight of the item . Veh icle speed is the most s ignificant factor .
For examp le, in a frontal collision at a speed of
30 mph (48 km/h), the forces act ing o n a 10-lb
256
(4.5 kg) object are about 20 times the normal
weight of the item . This means that the weight
of the item would s udden ly be about
200 lbs. (90 kg). You can imag ine the in juries
that a 200 lbs. (90 kg) item flying freely through
the passenger compartment could cause in a col­
l is ion like t his.
A WARNING
Weak, damaged or imp roper straps used to
secure items to tie-downs can fa il dur ing hard
b raking or in a coll is ion and cause ser io us pe r­
sona l injury .
- Always use s uitable mo unt ing st raps and
p roper ly sec ure i tems to the t ie -downs in
the l uggage compa rtment to help preven t
items from shifting or flying forward as dan ­
ge rous missi les .
- W hen the rear seat backrest is fo lded down,
a lways use s uitable mo unting straps and
properly sec ure items to the tie-downs in
the luggage compartment to help prevent items from flying forward as dangerous
m iss iles into the passenger compartment.
- Never attach a child safety seat tether strap
to a t ie-down.

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 chi ldren:
~ A lways use the right chi ld safety seat for each
c h ild and a lways use it properly
c::> page 300.
~ 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 be lt to insta ll a
c hi ld safety seat , you must first activate the
conve rtible locking retractor on the safety be lt
to prevent the child safety seat from mov ing
c::> page 305 .
~ Push the child safety seat down wit h your fu ll
weight to get the safety be lt 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 300 .
Always remember: Even though your vehicle is
equ ipped w ith an Advanced Airbag system, all
children, especially those 12 years and younger,
should always r ide in the back seat prope rly re­
stra ined fo r th eir age and size.
_& WARNING
N ot using a c hild safety seat, usi ng the w rong
c hild safety seat or imp roper ly installing a
298
chi ld restraint increases t he risk of serious
personal injury and death.
- All vehicle occ upants and especially children
must be restra ined properly whenever rid ing
in a vehicle. An unrestrained or improperly
restrained child cou ld be injured by strik ing
the inter ior or by being ejected from the ve­
h icle dur ing a sudden maneuve r o r i mpact.
An unrest rained or imprope rly rest rai ned
child is a lso at g rea ter r is k of inj ury o r death
through con ta ct w it h an infl ati ng a irbag.
- Commerc ia lly availab le child safety seats
a re requ ired to comply with U.S. Federal
Motor Vehicle S afety Standard ( FMVSS) 2 13
(in Canada CMVSS 213).
- When buying a child restra int, select one
that fits your chi ld and the vehicle .
- Only use child restra int systems that fully
contact the flat port ion of the seat cush­
i o n. The ch ild restraint must not tip or
lean to e ither side . Audi does not recom­
mend using child safety seats that rest on
l egs or tube -like frames. They do not p ro­
v ide adequate cont act wi th t he seat.
- Always heed all lega l req uirements per­
ta in ing to the inst allation and use of child
sa fe ty seats and caref ully follow the in ­
str uctions provided by the manufact urer
of the seat you are using .
- Never a llow children under 5 7 inc hes
( 1. 45 meters) to wear a normal safety be lt.
They must a lways be restrained by a proper
child restraint system. Otherwise, they
could sustain injuries to t he abdomen and
neck areas dur ing sudden brak ing maneu­
vers or accidents .
- Never let more than one c hild occupy a chi ld
safety seat.
- Never let babies or o lder ch ildren ride in a
ve hicle w hile sitting on the lap of a nother
passenger.
- Holding a c hild in your a rms is never a s ub­
stitute fo r a ch ild restraint system .
- The s tronges t person cou ld no t hold the
c hil d with the forces tha t exist in an acc i­
dent. The c hild will strike the inte rior of
the ve hicle and can also be struck by the
passenger.

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

A WARNING
A child in a child safety seat installed with the
LATCH lower anchorages or with the standard
safety belt or a child in a booster seat on the
rear seat could play with unused rear seat
safety belts and become entangled. This
could cause the child serious personal injury
and even death.
-Always secure unused rear seat safety belts out of reach of children in child seats such
as by properly routing them around the
300 head restraint of the seat where the child
restraint is installed .
- Never activate the convertible locking re­
tractor when routing the safety belts around
the head restraints.
-Never let anyone sit at the center rear seat­
ing position* if the center rear safety belt
has been routed around a rear head re­
straint.
Child safety seats
Infant seats
Babies and infants up to about one year old and
20 lbs. or
9 kg need special rearward-facing
child restraints that support the back, neck and
head in a crash.

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).
302
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. 249 and
c:> fig. 250 .
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 -facing child safety seat . It is a
very dangerous place for an infant or a larger
child in a rearward-facing seat .
.&_ WARNING
Not using a child safety seat, using the wrong
child safety seat or improperly installing a
child restraint increases the risk of serious
personal injury and death in a collision or oth­
er emergency situation.
-Children 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-facing child safety seat
installed on the front passenger seat will be
seriously injured and can be killed if the
front airbag inflates - even with an Ad­
vanced Airbag System .
-The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child
against the backrest, center arm rest, door
or roof.
-Always install rear-facing child safety seats
on the rear seat.
-If you must install a rearward facing child
safety seat on the front passenger seat be­
cause of exceptional circumstances and 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 child safety seat should
be positioned as close as possible to the
backrest on the vehicle seat.

chi ldren un til they are at least 4 ft. 9 in. (57 in­
ches/1. 45 meters) ta ll and weigh about 80 lbs.
(36 kg). Boos ter sea ts raise these chi ld ren up so
that t he safety bel t will pass properly over the
stronger parts of their bodies and the safety belt
can help protect them in a crash.
.. Do no t use the conve rtible locking retra ctor
when using the vehicle's safety belt to rest rai n
a chi ld on a booster seat.
.. The shoulder be lt must lie as close to the cen­
ter of the child's collar bone as possible and must lie flat and s nug on the upper body. It
must never lie across the throat or neck . The
lap belt must lie across the pelv is and never
ac ross the stomach or abdomen . Make sure the
belt lies flat and snug. Pull on the belt to tight­
en if ne cessa ry .
.. Applies to: vehicles with safety be lt height ad­
justment: If yo u must t ransport an older child
in a booster seat on the front passenger seat,
yo u can use the safety belt he ight adjustment

Ch ild ren up to at least 8 years old (over 40 lbs or
18 kg) are best protected in ch ild safety seats de­
signed fo r thei r age and we ight . Experts say that
the skeleta l struct ure, particularly the pelvis, of
304 t
h ese children is not fully developed, and they
must not use the vehicle safety belts without a
s ui tab le child restraint .
It is usually best to put t hese chi ld ren in appro­
priate booste r seats. Be sure the booste r seat
meets a ll applicab le safety standards .
Booster sea ts raise the seating posi tion of the
c hi ld a nd reposi tion both the lap and shoulde r
parts of the safety belt so that t hey pass across
the child 's body in the rig ht places. The routing of
the be lt over the ch ild's body is very important
for the chi ld's protection, whether o r not a boos­
ter seat is used. C hildren age 12 and under must
always ride in the rear seat .
Children who are at least 4 ft. 9 in. (57 inches/
1.45 meters) tall can generally use the vehicle 's
three point lap and shoulder belts. Never use the
l ap belt portion of the veh icle's safety belt a lone
to restra in any ch ild, regard less of how big t he
c hil d is . Always remember that chi ldren do not
h ave t he p ronounced pelvic str ucture required fo r
the p roper function of lap be lt po rtion of the ve­
hicle's three point la p and shoulder belts. The
c hil d's safety abso lutely requi res that a lap belt
portion of the safety belt be fastened snug ly and
as low as possib le aro und the pe lvis. Never let
the lap belt portion of the safety be lt pass over
the child's stomach or abdomen .
In a crash, airbags must inflate within a blink of
an eye and with considerab le force. In order to do
its job , the airbag needs room to inflate so that it
will be there to protect the occupant as the occu­ pant moves forward into the airbag .
A vehicle occupant who is out of pos it ion and too
close to the a irbag gets in the way of an inflating
airbag. When an occupant is too close, he or she
will be struck vio lent ly and w ill rece ive serio us or
possibly eve n fatal injury .
In order for the a irbag to offer protect ion, it is
importa nt that all vehicle occupants, especially
any ch ildren, who must be in the front seat be ­
cause of exceptiona l cir cumstances, be prope rly
r estra ined and as far aw ay from the a irbag as
poss ible. By keeping room between the chi ld's
body and the fron t of the passenger compa rt-
ment, the a irbag can inflate completely and
