& WARNING
Improperly stored luggage or other items can fly through the
vehicle causing serious personal 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 compartment .
• Always secure objects in the luggage compartment using the
tie-down hooks and suitable straps .
& WARNING
Heavy loads will influence the way your vehicle 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 compart-
ment 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. Exceeding permissible weight standards
can cause the vehicle to slide and handle differently.
• Please observe information on safe
driving => page 166.
& 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 because the rear lid cannot be fully closed.
& WARNING (continued)
• 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 panel,
- Switch off the air recirculation,
- Set the fresh air fan to the highest speed.
& WARNING
Always make sure that the doors, all windows, the power roof*
and the read 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 especially with the rear lid
left open. A child could crawl into the vehicle through the luggage
compartment and close the rear lid becoming trapped and unable
to get out . Being trapped in a vehicle can lead to serious personal
injury.
• Never let children play in or around the vehicle.
• Never let passengers ride in the luggage compartment . Vehicle
occupants must always be properly restrained in one of the
vehicle's seating positions.
[ i] Tips
Air circulation helps to reduce window fogging. Stale air escapes to
the outside through vents in the trim panel, on the left side of the
luggage compartment. Be sure to keep these slots free and open. •

Advanced Airbag System components
The front passenger seat in your vehicle has a lot of very impo rtant
parts of the Advanced A irbag System in it . These parts include the
we ight -sensing mat , sensors, wiring, brackets , and more. The func -tion of the system in the front passenger seat is checked by the e
lec ­
tronic contro l unit w hen t he ignit ion is on . The co ntrol uni t monitors
the Advanced Airbag System and turns the airbag indicator light on
whe n a malfunction i n the system components is detected. T he
function of the airbag ind icator light is described in greater detai l
below. Because the front passenger seat contains important parts
o f the Advanced Airbag System, you must take care to prevent it
from being damaged . Damage to the seat may prevent the
Advanced Airbag for the front passenger seat from do ing its job in
a crash .
The front Adva nc ed Airbag S ystem consi sts of th e
following :
• Crash sensors in the front of the ve hicle that measure veh ic le
acce leration/deceleration to provide information to the Advanced
A irbag System about t he severity of t he crash .
• An electronic control unit, with integrated crash sensors for front
and side impacts. The control unit "dec ides" whethe r to fire the
front airbags based on the information received from the crash sensors . The control unit also "dec ides" whether the safety be lt
pretensioners should be activated.
• A dual -stage Advanced Airbag with gas generator for the driver
inside the steering wheel hub.
• A dual-stage Advanced A irbag and gas generator inside the
instrument pane l for the front passenger .
• A we ight -sensing mat under the upholstery padding of the front
passenger seat cushion that measures the tota l weight on the seat .
T he information registered is sent continuously to the electronic
control un it to regu late dep loyment of the front Advanced Airbag on
the passenger side .

Airbag system 111111
-----------------------------=--=-------
It is important to remember that while the supplemental airbag
system is designed to reduce the likelihood of serious injuries, other
injuries, for example swelling, bruising and minor abrasions, can
also happen when airbags inflate. Airbags do not protect the arms
or the lower parts of the body. Front airbags only supplement the
three point safety belts in some frontal collisions in which the
vehicle deceleration is high enough to deploy the airbags.
Front airbags
will not deploy:
• if the ignition is switched off when a crash occurs,
• in side collisions,
• in rear -end collisions,
• in rollovers ,
• when the crash deceleration measured by the airbag system is
less than the minimum threshold needed for airbag deployment as
registered by the electronic control unit.
The front passenger airbag
will also not deploy:
• when the front passenger seat is not occupied,
• when the weight on the front passenger seat as sensed by the
Advanced Airbag System indicates that the front airbag on the
passenger side has to be turned off by the electronic control unit
(the PASSENGER AIR BAG OFF light comes on and stays onl.
& WARNING
Sitting in the wrong position can increase the risk of serious injury
in crashes.
• To reduce the risk of injury when the airbags inflate, the driver
and passengers must always sit in an upright position, must not
lean against or place any part of their body too close to the area
where the airbags are located.
• Occupants who are unbelted, out of position or too close to the
airbag can be seriously injured by an airbag as it unfolds with
great force in the blink of an
eye :::::, page 189.
Controls and equip­ ment Safety first
Vehicle operation
& WARNING
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 Advanced 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 because 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 .
& WARNING
Objects between you and the airbag will increase the risk of injury
in a crash by interfering with the way the airbag unfolds or by
being pushed into you as the airbag inflates .
• Never hold things in your hands or on your lap when the vehicle
is in use.
• Never transport items on or in the area of the front passenger
seat. Objects could move into the area of the front airbags during
braking or other sudden maneuver and become dangerous projec ­
tiles that can cause serious personal injury if the airbags inflate.
• Never place or attach accessories or other objects (such as cup
holders, telephone brackets, large, heavy or bulky objects) on the
doors, over or near the area marked "AIRBAG" on the steering
wheel, instrument panel, seat backrests or between those areas
and yourself. These objects could cause injury in a crash, espe­
cially when the airbags inflate.
• Never recline the front passenger's seat to transport objects.

The side curtain airbags are located on both sides of the interior
above the front and rear side
windows => fig. 183 . They are identi ­
fied by the word "AIRBAG" on the windshield frame and the center
roof pillar.
The side curtain airbag system supplements the safety belts and can help to reduce the risk of injury for occupants' heads and upper
torso on the s ide of the vehicle that is struck in a side collision . The
side curtain airbag inflates only in side impacts and only when the
vehicle accele ra tion reg istered by the contro l unit is high enough. If
this rate is below the reference va lue programmed into the contro l
unit, the side airbags w ill not be triggered, even though the car may
be badly damaged as a result of the co llision . It is not possible to
define an airbag triggering range that will cover every possible
angle of impact, since the circumstances will vary considerably
between one collision and ano the r. Important factors include, for
example, the nature (hard or soft) of the impacting object, the angle
Safety first
Airb ag syst em
of impact, vehicle speed, etc .=> page 208, "How side curtain airbags
work".
Aside from their norma l safety function, safety belts work to help
keep the driver or front passenger in position in the event of a colli ­
s ion so that the side curtain airbags can provide protection .
The airbag system is not a substitute for your safety belt . Rather, it
is part of the overall occupant restrain t system in your veh icle.
Always remember that the airbag system can only he lp to protect
you if you are wear ing your safety belt and wear ing it properly . This
is another reason why you should always wear your safety belts, not
just because the law requires you to do so
=> page 176, "General
notes".
It is important to remember that while the side curtain airbag
system is designed to help reduce the likelihood of serious injuries,
other injuries, for examp le, swelling, bruising, and minor abrasions
can a lso be associa ted with these a irbags . Remembe r too, these
airbags will deploy only once and on ly in certain kinds of accidents
- your safety belts are always there to offer protection .
The side curta in air b ag system b asi cally consists of :
• The elec tronic co ntrol mod ule and external side impact sensors
• The side curtain airbags above the front and rear side windows
• The airbag indicator light in the instrument panel
The airbag system is monitored electronica lly to make certain it is
f u n ction ing properly at all times. Each time you turn on the ignition,
the airbag system indicator light wi ll come on for a few seconds
(se lf diagnostics).
The s ide curt ain ai rbag is not acti vated :
• if the ignition is turned off,
• in side collisions when the acceleration measured by the sensor
is too low,
• in front -end collisions,
• in rear -end collisions,
