Warm and cold
Climate control
Description
The air conditioner is fully automatic and is designed to
maintain a comfortable and uniform climate inside the
vehicle.
We recommend the following settings:
- Set the temperature to 72 °F (+22 °C).
- Press the [AUTO
I button.
With this setting, you attain maximum comfort in the least amount
of time. Change this setting, as desired, to meet your personal
needs .
The climate controls are a combination of heating, ventilation and cooling systems, which automatically reduce humidity and cool the
air inside your vehicle.
The air temperature, air flow and air distribution are automatically
regulated to achieve and maintain the desired passenger compart
ment temperature as quickly as possible.
The system automatically compensates for changes in outside
temperature and for the intensity of the sunlight entering the
vehicle. We recommend you use the
Automatic mode:::::, page 126
for year -round comfort.
Please note the following:
Turn on the air conditioner to reduce humidity in the vehicle. This
also prevents the windows from fogging up.
When the outside temperature is high and the air is very humid,
condensation from the evaporator may drip under the vehicle . Th is
is normal and does not indicate a leak.
Controls and equip
ment
If the outside temperature is low, the fan normally only switches to
a higher speed once the engine coolant has warmed up sufficiently.
The air conditioner temporarily switches off when you drive off from
a standstill using full throttle to save engine power.
The compressor also switches off if the coolant temperature is too
high, so that the engine can be adequately cooled under extreme
loads.
Air pollutants filter
The air pollutants filter (a combined particle filter and activated
charcoal filter) reduces or prevents outside air pollution (dust, or
pollen) from entering the vehicle. The air is also filtered in air recir
culation mode.
The air pollutants filter must be changed at the intervals specified in your Warranty
& Maintenance booklet, so that the air conditioner
can properly work.
If you drive your vehicle in an area with high air pollution, the filter
may need to be changed more frequently than specified in your
Audi Warranty
& Maintenance booklet . If in doubt, ask your autho
rized Audi Service Advisor for advice.
Key coded settings
The air conditioner settings selected are automatically stored and assigned to the key being used. When the vehicle is started, the air
conditioner automatically selects the settings assigned to that key.
This way every driver will maintain his/her own personal settings
and does not have to reset them manually.
If a different driver uses your key and changes the air conditioner
settings, the latest adjustments will erase and replace the settings
you have stored. _.,

What impa
irs 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
become a hazard to everyone else on the road :::>& .There
fore:
- Do not let yourself be distracted by passengers or by
using a cellula r 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 .
& WARNING
Impaired driving safety increases the risk of serious personal
injury and death whenever a vehicle is being used. •

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 deploys .
• 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 safety seats

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 risk 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 225.
-Keep both feet flat on the floor in front of the front
passenger seat.
- Fasten and wear safety belts correctly=:>
page 235.
For detailed information on how to adjust the front passenger's
seat, see
=> page 92.
& WARNING
Front seat passengers who are unbelted, out of position or too
close to the airbag can be seriously injured or killed by the airbag

Proper adjustment of head restraints
Correctly adjusted head restraints are an important part
of your vehicle's occupant restraint system and can help
to reduce the risk of injuries in accident situations.
Fig. 237 Correctly
adjusted head restraint
viewed from the side
The head restraints must be correctly adjusted to achieve
the best protection.
-Adjust the head restraint so that the upper edge of the
restraint is level with the top of your head, but no lower
than eye level and so it is as close to the back of your
head as possible ~
page 225, fig. 237.
Adjusting head restraints=> page 101.
& WARNING
Driving without head restraints or with improperly adjusted head
restraints increases the risk of serious injuries in a collision . To
help reduce the risk of injury :
• Always drive with the head restraints in place and properly
adjusted.
• Every person in the vehicle must have a properly adjusted head
restraint.
Controls and equip ment Safety first Vehicle operation
& 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 263. •
Examples of improper seating positions
The occupant restraint system can only reduce the risk of
injury if vehicle occupants ore 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 bulletins list only some sample positions that will
increase the risk of serious injury and death. Our hope is that these .,_

Safety be lt pretensioners
How safety belt pretensioners work
In front, side and rear-end collisions above a particular
severity and in a rollover, safety belts are tensioned auto
matically.
The safety belts are equipped with safety belt pretensioners . The
system is activated by sensors in front, side and rear -end collisions
of great severity and in a rollover. This tightens the belt and takes up
belt slack ~
& in "Service and disposal of safety belt pretensioner"
on
page 240. Taking up the slack helps to reduce forward occupant
movement during a collision.
0 Note
Never let the belt remain over a rear seat back that has been folded
forward.
[ i] Tips
The safety belt pretensioner can only be activated once.
• In minor frontal and side collisions, in rear -end collisions and in
accidents involving very little impact force, the safety belt preten
sioner are not activated .
• When the safety belt pretensioners are 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. An authorized ._

Airbag system
Important things to know
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints. For airbags to
do their job, occupants must always properly wear their
safety belts and be in a proper seating position.
For your safety and the safety of your passengers, before
driving off, always:
- Adjust the driver's seat and steering wheel properly
=>
page 222,
-Adjust the front passenger's seat properly=> page 93,
-Wear safety belts properly=> page 234,
- Always properly use the proper child restraint to protect
children =>
page 263.
In a collision, airbags must inflate within the blink of an eye and with
considerable force . The supplemental airbags can cause injuries if
the driver or the front seat passenger is not seated properly. There
fore in order to help the airbag to do its job, it is important, both as
a driver and as a passenger to sit properly at all times.
By keeping room between your body and the steering wheel and the
front of the passenger compartment, the airbag can inflate fully and
completely and provide supplemental protection in certain frontal
collisions =>
page 222, "Proper occupant seating positions". For
details on the operation of the seat adjustment controls=>
page 93.
It's especially important that children are properly restrained
=>
page 263.
Controls and equip ment Safety first Vehicle operation
There is a lot that the driver and the passengers can and must do to
help the individual safety features installed in your Audi work
together as a system .
Proper seating position is important so that the front airbag on the
driver side can do its job. If you have a physical impairment or
condition that prevents you from sitting properly on the driver seat
with the safety belt properly fastened and reaching the pedals, or if
you have concerns with regard to the function or operation of the
Advanced Airbag System, please contact your authorized Audi dealer or qualified workshop, or call Audi Customer CARE at 1-800-
822 -2834 for possible modifications to your vehicle.
When the airbag system deploys, a gas generator will fill the
airbags, break open the padded covers, and inflate between the
steering wheel and the driver and between the instrument panel
and the front passenger. The airbags will deflate immediately after
deployment so that the front occupants can see through the wind
shield again without interruption .
All of this takes place in the blink of an eye, so fast that many people don't even realize that the airbags have deployed. The airbags also
inflate with a great deal of force and nothing should be in their way
when they deploy. Front airbags in combination with properly worn
safety belts slow down and limit the occupant's forward movement .
Together they help to prevent the driver and front seat passenger
from hitting parts of the inside of the vehicle while reducing the
forces acting on the occupant during the crash. In this way they help
to reduce the risk of injury to the head and upper body in the crash.
Airbags do not protect the arms or the lower parts of the body.
Both front airbags will not inflate in all frontal collisions. The trig
gering of the airbag system depends on the vehicle deceleration
rate caused by the collision and registered by the electronic control
unit. If this rate is below the reference value programmed into the
control unit, the airbags will not be triggered, even though the car
may be badly damaged as a result of the collision. Vehicle damage,

Child restraints on the front seat -some
important things to know
- Be sure to read the important information and heed the
WARNINGS for important details about children and
Advanced Airbags :=>
page 263.
Even though your vehicle is equipped with an Advanced Airbag
System, make certain that all children, especially those 12 years and
younger, always ride in the back seat properly restrained for their age and size . 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
can be a very dangerous place for an infant or a child in a rearward
facing seat.
The Advanced Airbag System in your vehicle has been certified to
comply with the requirements of United States Federal Motor
Vehicle Safety Standard 208 as applicable at the time your vehicle
was manufactured.
The Standard requires the front airbag on the passenger side to be
turned off ("suppressed") if a child up to about one year of age
restrained in one of the rear-facing or forward-facing infant
restraints listed in Federal Motor Vehicle Safety Standard 208 with
which the Advanced Airbag System in your vehicle was certified has been installed on the front passenger seat. For a listing of the child
restraints that were used to certify compliance with the US Safety
Standard =>
page 265.
The PASSENGER AIR BAG OFF light in the instrument panel tells you
when the front Advanced Airbag on the passenger side has been
turned off by the electronic control unit.
Each time you turn on the ignition, the
PASSENGER AIR BAG OFF
light will come on for a few seconds and:
• will stay on if the front passenger seat is not occupied
Controls and equip
ment Safety first Vehicle operation
•
will stay on if there is a small child or child restraint on the front
passenger seat
• will go off if the front passenger seat is occupied by an adult as
registered by the weight-sensing mat=>
page 252, "Monitoring the
Advanced Airbag System" .
The
PASSENGER AIR BAG OFF light comes on when the control unit
detects a total weight on the front passenger seat that requires the
front airbag to be turned off.
If the total weight on the front passenger seat is more than that of
a typical 1 year-old child but less than the weight of a small adult,
the front airbag on the passenger side can deploy (the
PASSENGER
AIR BAG OFF
light does not come on). If the PASSENGER AIR BAG
OFF
light does not come on, the front airbag on the passenger side
has not been turned off by the electronic control unit and can
deploy if the control unit senses an impact that meets the condi
tions stored in its memory.
For example, the airbag may deploy if:
• a small child that is heavier than a typical 1 year -old child is on
the front passenger seat (regardless of whether the child is in one
of the child safety seats listed=>
page 265), or
• a child who has outgrown child restraints is on the front
passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG
OFF
light comes on in the instrument cluster and stays on.
The front airbag on the passenger side may
not deploy (the
PASSENGER AIR BAG OFF light does not illuminate and stay lit) even
if a small adult or teenager, or a passenger who is not sitting upright
with their back against a non-reclined backrest with their feet on the
vehicle floor in front of the seat is on the front passenger seat
=>
page 222, "Proper seating position for the driver".
If the front passenger airbag deploys, the Federal Standard requires
the airbag to meet the "low risk" deployment criteria to reduce the risk of injury through interaction with the airbag . "Low risk" deploy
ment occurs in those crashes that take place at lower decelerations
