The pollutant filter (particle filter) ensures that contaminants in the
outside air (such as dust or po llen) are grea tly reduced or stopped.
T he air is also filtered in recirculation mode.
The pollutant fil ter e lement must be changed according to the inter ­
vals specified in the maintenance schedu le so that the air condi­
tioning system's performance is not adversely affected.
If the fil ter's effectiveness is weakened by driving the vehicle in
areas with heavi ly polluted outside air, the filter element should also
be changed in between the listed services .

the event of malfunct ions.
[ i ] Tip s
• To avoid adversely affecting heating and cooling performance
and to prevent condensation on the windows, the air intake in front
of the windsh ield must be free of ice, snow, and leaves.
• The air coming from the vents and circu lating through the en tire
interior is extracted through the out let slots in the side panels in the
luggage compartment. Make sure that the outlet slots are not
covered by clo th ing, etc.
• Climate control works most effectively if the windows are closed .
However , if the interior o f a parked vehicle is extremely hot from the
sun's rays, briefly opening the windows can speed up the cooling
process. •

What impairs driving safety?
Safe driving is directly related to the condition of the
vehicle, the driver as well as the driver's ability to concen­
trate on the road without being distracted.
The driver is responsible for the safety of the vehicle and all
of its occupants. If your ability to drive is impaired, safety risks for everybody in the vehicle increase and you also
Controls and equip­ ment Safety first Vehicle operation
become a
hazard to everyone else on the road =>&, .There ­
fore:
- Do not let yourself be distracted by passengers or by
using a cellular telephone.
- NEVER drive when your driving ability is impaired (by
medications, alcohol, drugs, etc .).
- Observe all traffic laws, rules of the road and speed limits
and plain common sense.
- ALWAYS adjust your speed to road, traffic and weather
conditions.
- Take frequent breaks on long trips. Do not drive for more
than two hours at a stretch.
- Do NOT drive when you are tired, under pressure or when
you are stressed.

Driving Safely -
----------------
& WARNING (continued)
• Always adjust the driver's seat and the steering wheel so that
there are at least 4 inches (10 cm) between the knees and the
lower part of the instrument panel.
• Always hold the steering wheel on the outside of the steering
wheel rim with your hands at the 9 o'clock and 3 o'clock positions
to help reduce the risk of personal injury if the driver's airbag inflates .
• Never hold the steering wheel at the 12 o'clock position or with
your hands at other positions inside the steering wheel rim or on
the steering wheel hub. Holding the steering wheel the wrong way
can cause serious injuries to the hands, arms and head if the
driver's airbag inflates
• Pointing the steering wheel toward your face decreases the
ability of the supplemental driver's airbag to protect you in a colli­
sion .
• Always sit in an upright position and never lean against or
place any part of your body too close to the area where the airbags
are located.
• Before driving, always adjust the front seats and head
restraints properly and make sure that all passengers are properly
restrained .
• Never adjust the seats while the vehicle is moving. Your seat
may move unexpectedly and you could lose control of the vehicle.
• 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 168. Special
precautions apply when installing a child seat on the front
passenger seat=>

Proper seating position for the front
passenger
The proper front passenger seating position is important
for safe, relaxed driving.
For your own safety and to reduce the ris k of injury in the
event of an accident, we recommend that you adjust the
seat for the front passenger to the following pos ition:
- Move the front passenger seat back as far as possible.
There must be a minimum of 10 inches (25 cm) between
the breastbone and the instrument panel =>
&.
- Adjust the angle of the seatback so that it is in an upright
position and your back comes in full contact with it
whenever the vehicle is moving.
- Adjust the head restraint so that the upper edge is as
even with the top of your head as possible but not lower
than eye level and so that it is as close to the back of your
head as possible =>
page 132.
-Keep both feet flat on the floor in front of the front
passenger seat.
- Fasten and wear safety belts correctly=>
page 141.
For detailed information on how to adjust the front passenger's
seat, see => page 87.

& WARNING (continued)
• Always make sure each person in the vehicle properly adjusts
their head restraint. Each head restraint must be adjusted
according to occupants' size so that the upper edge is as even
with the top of the person's head, but no lower than eye level and so it is as close to the back of to the head as possible .
• Never attempt to adjust head restraint while driving.
If you
have driven off and must adjust the driver headrest for any reason,
first stop the vehicle safely before attempting to adjust the head
restraint.
• Children must always be properly restrained in a child restraint
that is appropriate for their age and size~
page 168. •
Examples of improper seating positions
The occupant restraint system can only reduce the risk of
injury if vehicle occupants are properly seated.
Improper seating positions can cause serious injury or
death. Safety belts can only work when they are properly
positioned on the body. Improper seating positions reduce
the effectiveness of safety belts and will even increase the
risk of injury and death by moving the safety belt to critical
areas of the body. Improper seating positions also increase
the risk of serious injury and death when an airbag deploys
and strikes an occupant who is not in the proper seating
position. A driver is responsible for the safety of all vehicle
occupants and especially for children. Therefore:
- Never allow anyone to assume an incorrect seating posi­
tion when the vehicle is being used::::;,
&-
The following bullets list only some sample positions that will
increase the risk of serious injury and death . Our hope is that these
Controls and equip­
ment Safety first Vehicle operation
examples will make you more aware of seating positions that are
dangerous.
Therefore, whenever the
vehicle is moving:
• never stand up in the vehicle
• never stand on the seats
• never kneel on the seats
• never ride with the seatback reclined
• never lie down on the rear seat
• never lean up against the instrument panel
• never sit on the edge of the seat
• never sit sideways
• never lean out the window
• never put your feet out the window
• never put your feet on the instrument panel
• never rest your feet on the seat cushion or back of the seat
• never ride in the footwell
• never ride in the cargo area
& WARNING
Improper seating positions increase the risk of serious personal
injury and death whenever a vehicle is being used.
• Always make sure that all vehicle occupants stay in a proper
seating position and are properly restrained whenever the vehicle
is being used. •

coverings will reduce the size of the pedal area and interfere 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 foot­
well while the vehicle is moving. Objects can become trapped
under the brake pedal and accelerator pedal causing a loss of
vehicle control . •
Stovving luggage
Loading the luggage compartment
All luggage and other objects must be properly stowed
and secured in the luggage compartment.
Loose items in the luggage compartment can shift
suddenly, changing vehicle handling characteristics. Loose items can also increase the risk of serious personal injury in
a sudden vehicle maneuver or in a collision.
- Distribute the load evenly in the lugg age compartment.
- Always place and properly secure heavy items in the
luggage compartment as far forward as possible.
Controls and equip­
ment Safety first

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.

Improperly worn safety belts
Incorrectly positioned safety belts can cause severe inju­
ries.
Wearing safety belts improperly can cause serious injury or
death. Safety belts can only work when they are correctly positioned on the body. Improper seating positions reduce
the effectiveness of safety belts and will even increase the
risk of injury and death by moving the safety belt to critical
areas of the body. Improper seating positions also increase
the risk of serious injury and death when an airbag deploys
and strikes an occupant who is not in the correct seating
position. A driver is responsible for the safety of all vehicle
occupants and especially for children. Therefore:

tion in the vehicle while traveling~&.
& WARNING
Improperly worn safety belts increase the risk of serious personal
injury and death whenever a vehicle is being used.
• Always make sure that all vehicle occupants are correctly
restrained and stay in a correct seating position whenever the
vehicle is being used.

Safety belt tensioners
How safety belt pretensioners work
In front and side collisions above a particular severity,
safety belts in use are tensioned automatically.
The safety belts are equipped with safety belt pretensioners . The
system is activated by sensors in front and side collisions of great
severity . This tightens the belt and takes up belt slack=>&. in
"Service and disposal of safety belt pretensioner". Taking up the
slack helps to reduce forward occupant movement during a colli­
sion.
[ i] Tips
The safety belt pretensioner can only be activated once.
• In minor frontal and side collisions, in rear-end collisions, in a
rollover and in accidents involving very little impact force, the safety
belt pretensioner are not activated.
• When the safety belt pretensioner is activated, a fine dust is
released. This is normal and is not caused by a fire in the vehicle.
• The relevant safety requirements must be observed when the
vehicle or components of the system are scrapped . A qualified deal­
ership is familiar with these regulations and will be pleased to pass
on the information to you.
• Be sure to observe all safety, environmental and other regula ­
tions if the vehicle or individual parts of the system, particularly the
safety belt or airbag, are to be disposed. We recommend you have
your authorized Audi dealer perform this service for you. •
