92 Warm and cold
Warm and cold Climate control
Description
The air conditioner is fully automatic and is
designed to maintain a comfortable and uni­
form climat e inside the vehicle .
We recommend the following sett ings :
.. Set the temperature to 72 °F (+ 22 °C).
.. Press the
!AUTO ! button.
W ith this setting, you attain maxim um com ­
fort i n the least amount of time. Change this
setting, as desired, to meet yo ur persona l
needs.
The climate controls are a combination o f
heating, venti lation and cooling systems,
which automatica lly reduce humidity and cool
the air inside your vehicle.
The air tempera ture, a ir flow and air distrib u­
tion are automatica lly regu lated to achieve
and maintain the desired passenger compart­
ment temperature as quick ly as possib le.
The system a utomatically compensates for
changes in outside temperature and for the
intensity of the sunlight entering the ve hicle .
We recommend you use the
Automati c mode
¢ page 95 for year-round comfort.
Please note the following:
Turn on the ai r cond itione r to reduce hum idity
i n the vehicle . Thi s also p revents the w indows
from fogging up .
When the outside temperature is high and the
a ir i s very hum id,
c ondensation from the
evapo rator may drip unde r the ve hicle. This is
norma l and does not indicate a leak.
I f the outside temperatu re is low, the fan nor­
mally only switches to a h igher speed once
the eng ine coolan t has warmed up sufficient­
l y.
The air conditioner tempora rily switches off
when you d rive off from a s tandstill using full
thro ttle to s ave eng ine power. T
he compressor a lso switches off if the coo l­
ant temperature is too high , so that the en­
gine can be adequately cooled under extreme
l oads.
Air pollutant s filter
The air pollutan ts f ilter (a comb ined particle
filte r and activated charcoa l filter) reduces o r
prevents outside air po llution (dust, or pollen)
from enter ing the veh icle. The air is a lso fil­
tered in a ir recirculation mode .
The air pollutants fi lter m ust be changed at
the interva ls specified in yo ur War ranty
&
Maintenance booklet, so that the a ir cond i­
tioner can properly work.
If you drive your vehicle in an area with high
air poll ution, the filter may need to be
changed more frequently than specif ied in
your Audi Warranty
& Maintenance book let. If
in doubt, ask your authorized Audi Service Ad­
visor for advice .
Key coded settings
The air conditioner settings selected are auto­
matically stored and assigned to the key be ing
used. When the vehicle is started, the air con­
ditioner automa tically selects the settings as­
s igned to that key . This way every driver will
mainta in his/her own pe rsonal settings and
does not have to reset them manually .
If a different dr iver uses your key and changes
the a ir cond itione r settings, the latest adjust ­
ments will e rase and replace the sett ings you
have stored.
Energy man agement
To prevent the battery from being discharged
and to restore the ba lance of energy, compo­
nents which require large amounts of energy
are temporarily cut back or switched off
¢ page 229. Heating systems in pa rticular re­
quire a grea t deal of ene rgy.
If yo u notice , fo r
example, that the seat* or rear window hea t­
ing is not heating, they have been temporar ily
cut back or switched off by
energy manage­
ment .
These systems are availab le aga in as
soon as the energy balance has been restored . .,.

Improperly worn safety belts
Incorrectly positioned safety belts can cause
severe injuries .
Wearing safety belts improperly can cause se­
rious 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 mov­
ing the safety belt to critical areas of the
body . Improper seating positions also in­
crease the risk of serious injury and death
when an airbag deploys and strikes an occu­
pant who is not in the correct seating posi­
tion . A driver is responsible for the safety of
all vehicle occupants and especially for chil­
dren . Therefore:
... Never permit anyone to assume an incorrect
sitting position in the vehicle while traveling
¢ ,& .
A 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 occu­
pants are correctly restrained and stay in
a correct seating posit ion whenever the
vehicle is be ing used.
- Always read and heed all WARNINGS and
other important information

Safety belt preten­
sioners
How safety belt pretensioners work
In front, side and rear -end collisions above a
particular severity and in a rollover, safety
belts are tensioned automatically.
The safety belts are equipped with safety belt
pretensioners . The system is activated by sen­
sors in front, side and rear-end collisions of
great severity and in a rollover. This tightens
the belt and takes up be lt sla ck

page 182.
Taking up the slack helps to reduce
forward occupant movement dur ing a colli­
sion.
@ Note
Never let the belt remain over a rear seat­
back that has been fo lded forward.
(D Tips
The safety belt pretensioner can only be
activated once.
- In minor frontal and side collisions, in
rear-end collisions and in accidents in­
volving very little impact force, the safe­
ty belt pretensioner are not activated.
- When the safety belt pretensioners are
activated, a fine dust is re leased. This is
normal and is not caused by a fire in the
vehicle.
- The re levant safety requirements must
be observed when the vehicle or compo­
nents of the system are scrapped. An au­
thorized Audi dealer or qualified work­
shop is familiar w ith these regulations
and w ill be pleased to pass on the infor­
mation to you.
- Be sure to observe all safety, env iron­
menta l and other regulations if the veh i­
cle or ind ividual parts of the system, par­
ticularly the safety belt or airbag, are to
be disposed. We recommend you have
your authorized Audi dealer perform this
service for you.
Service and disposal of safety belt
pretensioner
The safety belt pretens ioners are parts of the
safety belts on your Audi. Insta lling, remov­
ing, servic ing or repair ing of belt pretension­
ers can damage the safety belt system and
prevent it from working correctly in a colli­
s ion .

the system will not be impaired and that dis­
carded components do not cause injury or pollute the environment .
.&_ WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing a safety belt
pretensioner from activating when needed
or activating it unexpectedly:
- The belt pretensioner system can be acti­
vated only once . If belt pretensioners
have been activated, the system must be
replaced.
- Never repair, adjust, or change any parts
of the safety belt system.
- Safety belt systems including safety belt
pretensioners cannot be repaired. Spe­
cial procedures are required for removal,
installation and disposal of this system.
- For any work on the safety belt system,
we strongly recommend that you see
your authorized Audi dealer or qualified
technician who has an Audi approved re­
pair manual, training and special equip­
ment necessary.
@) 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/haza rdouswaste/per­
chlorate. When the vehicle or parts of the restraint system including airbag modules

@ For the sake of the environment
Undep loyed airbag modu les and preten­
sioners might be classified as Perchlorate Material -special handling may app ly, see
www.dtsc.ca.gov/haza rdouswaste/per­ chlorate. When the vehicle or parts of the
restraint system including airbag modules
and safety belts w ith pretens ioners are

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-r im combinations not approved by Aud i,
l owering the vehicle, changing the stiffness o f
the suspension, including the springs, s uspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic control
un it. Some suspension changes can, for exam­
ple, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in wh ich it would not deploy if the
changes had not been made. Other kinds of
changes may reduce the force levels meas ­
u red by the sensors and prevent the airbag
from deploying when it should .
The sensors in the safety belt buckle for the
driver and front passenger sea t tell the elec­
tronic control module if the safety belt is
latched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high­
er rate of vehicle deceleration than if the safe­
ty belt is not being used. Therefore, in a par­
ticular collision, it is possible that an airbag
will not deploy at a seating position where the safety belt is being used but will inflate at the
position where the safety belt is not being
used.
It is important that nothing interfere
with the safety belt buckles so that the sen- sors can send the correct info
rmation about
safety belt use to the electronic control unit.
.&_ WARNING
-
Changing the vehicle's suspension includ- ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
formance and increase the risk of serious
personal injury in a crash.
- Never install suspension components
that do not have the same performance
characteristics as the components origi­
nally installed on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
&_ WARNING
--
Items stored between the safety be lt
buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the e lectronic con­
trol module and prevent the Advanced Air ­
bag System from working properly.
- Always make sure that nothing can inter­
fere with the safety belt buckles and that
they are not obstructed.
Side airbags
Description of side airbag s
The airbag system can provide supplemental
protection to properly restrained occupants.
Fig. 211 Side airbag location in th e drive r's seat
The side airbags are located in the sides of the
front seat backrests

Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
11-Shut the engine off when you are not driving
the vehicle.
11-Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traffic
jams, when waiting for trains to pass at rail­
road cross ings, or at traffic lights that have
long waits on red. Turning the engine
off for
just 30-40 seconds saves more fuel than is
burned starting the engine again.
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up .
(D Note
Do not leave engine idling unattended af­
ter starting. If warning lights should come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over­
heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel .
11-Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
authorized Audi dealer helps to ensure that it
runs properly and economically. The condition
of your vehicle not only affects its safe ty and
ab ility to hold its value, it also affects fuel
consumption .
Check your oil each time you fill your tank.
Driving and environment 235
The amount of oil used is re lated to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven.
You must drive your vehicle about 3,000 miles
(S,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(D Note
- Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
t enance booklet. Lack of prop er mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission cont ro l system and could lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
11-Try to avoid driv ing short distances w ith a
cold engine.
T he engine and cata lytic converter have to
reach their optimal operating temperature to
reduce fuel consumpt ion and noxious emis­
s ions effectively .
Just after starting, a co ld engine in a mid-size
car on ly achieves a fuel economy of 6-8 mi les
per gallon (30-40 l/l00km). After about a
half a mile, fuel economy climbs to 12 mpg
(20 l/100 km). After about
2 .5 miles (4 km), liJI,

250 Fuel supply and filling your fuel tank
-Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
especially well for winter or summer driving. During seasonal change-over, we suggest that
you fill up at busy gas stations where the sea­
sonal adjustment is more likely to be made in
time.
(CT) Note
- Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system.
- Do not use fuels that fail to meet the
specified criteria in this chapter.
- If you are unable to determine whether
or not a particular fuel blend meets the
specifications, ask your service station or
its fuel supplier.
- Do not use fuel for which the contents cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility of Audi and are not
covered under the New Vehicle or the
Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob­ lems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
Applies to vehicles: with gasoline engine
A major concern among many auto manufac­
turers is carbon deposit build-up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another, they have certain
things in common. All gasoline grades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline brands include additives to keep engine and
fuel systems clean, they are not equally effec­
tive.
Audi recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your
engine of peak performance.
(D Note
Damage or malfunction due to poor fuel
quality is not covered by the Audi New Ve­
hicle Limited Warranty.
Diesel fuel
Applies to vehicles: with diesel engine
Always use ULSD (Ultra Low Sulfur Diesel) sul­
fur content 15 ppm or less.
The ULSD (Ultra Low Sulfur Diesel) meets the
ASTM-D-975 (grade 2).
Diesel fuel with a higher concentration than
ULSD-Diesel No. 2 ASTM D975 and Bio-die­
sel with a higher concentration than 5
% like
811, 820 or 8100 are strictly prohibited.
Service station fuel pumps are labeled with
the correct fuel information for easy recogni­
tion by the user. If the diesel fuel pump is not
labeled ask the station operator what fuel is
being dispensed before filling up your vehicle.
Service stations offering Diesel fuel are gener­
ally located on truck routes or major high­
ways. Directories of Diesel fuel stations are usually available at Diesel fuel stations.
Some states in the USA require permits to
purchase Diesel fuel. Check with your State
Motor Vehicle Department.
Diesel fuel may not be available outside the
USA and Canada. Be sure to check before trav-
eling to other countries.
