area because 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 top,
- Open all air outlets in the instrument
panel,
- Switch off the air recirculation,
- Set the fresh air fan to the highest
speed.
A WARNING
Always make sure that the doors, all win­
dows, 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 es­
pecially 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.
(D Tips
- Air circulation helps to reduce window
fogging. 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 la­ bel is located on the driver's side B-pillar.
The tire pressure label lists the recom­ mended 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 manufactured.
For recommended tire pressures for nor­
mal load conditions, please see chapter
¢page 217.
Tie-downs
Applies to vehicles : wi th t ie-downs
The luggage compartment is equipped with
four tie-downs to secure luggage and other
items.
Use the tie-downs to secure your cargo prop­
erly
¢ page 118, Loading the luggage com­
partment .
In a collision, the laws of physics mean that
even smaller items that are loose in the vehi­
cle will become heavy missiles that can cause
serious injury. Items in the vehicle possess en­
ergy 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 collision like this.
A WARNING
Weak, damaged or improper straps used
to secure items to tie-downs can fail dur­ ing hard braking or in a collision and cause
serious personal injury.
- Always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help pre­
vent items from shifting or flying for­
ward as dangerous 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

-Never attach any objects such as cu­
pholders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
-All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including the installation of audio
equipment , cellular telephones and CB
radios, etc.) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work­
shop.
- Never modify the front bumper or parts
of the vehicle body .
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­
ment upholstery over the front seat­ backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can be activated only
once. After an airbag has inflated, it must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only
once. After an airbag has been deployed,
it must be replaced with new replace-

cially for your Audi model version . Re­
placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only. Make sure that any airbag service action
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- In accidents when an airbag is deployed,
the vehicle battery separates the alterna­
tor and the starter from the vehicle elec­
trical system for safety reasons with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a
qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.
@ For the sake of the environment
Undeployed airbag modules and preten ­
sioners might be classified as Perchlorate
Material -special handling may apply, see
www .dtsc.ca.gov/hazardouswaste/per-
ch lorate. When the vehicle or parts of the
restraint system including airbag modules
safety belts with pretensioners are scrap­
ped, all applicable laws and regulations
must be observed. Your authorized Audi
dealer is familiar with these requirements
and we recommend that you have your
dealer perform this service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi ,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic control unit. Some suspension changes can, for
