- Always check t hat the wiper blades are
not frozen to the glass before yo u turn
the wiper on. loosen a wiper blade which i s frozen in p lace before operating the
wipe r to preve nt damage to the wiper
blade o r the w ip er motor .
-
-Do not use the wiper to clear a frosted
window . Using the wipers as a conven ­
i ent ice sc raper will destroy the w iper
blades .

Warm and cold Climate controls
Description
The air conditioner is fully automatic and is
designed to maintain a comfortable and uni­
form climate inside the vehicle .
We recommend the following settings:
... Se lect and set a temperature between 64 °F
(+ 22 °C) and 84 °F (+28 °C).
... Press the
!AU TO ! button.
With this setting, you attain maximum com­
fort 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 distribu­
tion are automatica lly regulated to achieve
and maintain the desired passenger compart­
ment temperature as quickly as possib le.
The system automatically compensates for
changes in the outside temperature and for
the intensity of the sunlight entering the vehi­
cle. We recommend you use the
Automatic
mode c> page 81 for year-round comfort.
Please note the following:
Turn on the air conditioner to reduce humidity
in the vehicle. This also p revent the windows
from fogging up .
When the outside temperature is high and the
air is very hum id,
condensation from the
evaporator may drip under the vehicle . This is
normal and does not indicate a leak.
If the outside temperature is low, the fan nor­
mally only switches to a h igher speed once
the engine coolant has warmed up sufficient ­
ly.
Warm and cold 79
T he air conditioner temporari ly switches off
when you drive off from a standstill using full
throttle to save engine power.
T he compressor also switches off if the cool­
ant temperature is too high so that the engine
can be adequately cooled under extreme
l oads.
Air pollutants filter
T he air pollutants filter (a combined particle
filter and activated charcoa l filter) reduces or
eliminates outside air pollution (dust, or pol­
l en) from entering the vehicle .
T he air pollutants filter must be changed at
the interva ls specified in yo ur Warranty
&
Maintenance booklet, so that the air condi ­
tioner 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 authorized Audi Service Ad­
visor for advice.
Energy management
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 c> page 167. Heating systems in particular re­
quire a great deal of energy. If you notice, for
example, that the rear window heater is not
heating, then it has been temporarily cut back
o r switched off by
energy management.
These systems are available again as soon as
the energy balance has been restored.
_& WARNING
.-----
Reduced visibility is dangerous and can
cause accidents .
- For safe driving it is very important that
all windows be free of ice, snow and con-
densation.
- Fully familiarize yourself with the proper
use and function of the heating and ven­
tilation system and especia lly how to de­
fog and defrost the windows.

120 Safety belts
Safety belt preten­
sioners
How safety belt pretensioners work
In front, side ond rear end collisions above a
particular severity, safety belts are tensioned automatically.
The safety belts are equipped with safety be lt
p retensioners. The system is activated by sen ­
sors in front, side and rear-end collisions of
g reat severity. This tight ens the belt and takes
up be lt slack ~
& in Service and disposal of
safety belt pretensioner on page 120 .
Taking
up the slack helps to reduce forward occupant
movement during a collision.
Never let the be lt remain over a rear seat­
back that has been folded forward.
The safety be lt pretensioners can only be
activated once.
-In m inor frontal and side coll isions, in
rear-end collisions, in a rollover and in
accidents involving very little impact
force, the safety belt pretensioner are
not act ivated.
- When the safety belt pretensioners are
activated, a fine dust is released. This is
normal and is not caused by a f ire in the
vehicle .
- The relevant safety requirements must
be observed when the vehicle or compo­
nents of the system are scrapped . A
qualified workshop is familiar with these
r egulations and will be pleased to pass
on the information to you.
- Be sure to observe all safety, environ­
mental and other regulations if the vehi­
cle or indiv idual pa rts of the system, par­
ticularly the safety belt or airbag, are to
be disposed. We recommend you have
your a uthorized Audi dealer perform this
serv ice for you .
Service and disposal of safety belt
pretensioner
The safety belt pre-tensioners are parts of the
safety belt and installed at the outboard seat­
ing pos itions on your Audi. Installing, remov ­
ing, servicing or repairing of be lt pre-tension­
ers can damage the safety belt system and
prevent that system from working properly in
a coll is ion.
There are some important things you have to
know to make sure that the effectiveness of
the system will not be impaired and that dis­
carded components do not cause injury or pol­
lute 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
tensioner from activating when needed or
activating it unexpectedly:
- The safety be lt pre-tensioner system can
be activated on ly once. If safety belt pre­
tensioners have been activated, then
they must be replaced .
- Never repair, adjust, or change any parts
of the safety be lt system.
- Safety belt systems including safety belt
pre-tensioners cannot be repaired. Spe ­
cial procedures are required for removal,
installation and disposal of th is system.
- For any work on the safety belt system,
we strongly recommend that you see
your authorized Audi dealer or qualified
technician who has a Audi approved re­
pa ir manual, train ing and special equ ip­
ment necessary .
@ For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate

working properly in a collision.
There are some important things you have to know to make sure that the effectiveness of
the system will not be impaired and that dis­
carded components do not cause injury or pol­
lute the environment.
.&_ WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag
from deploying when needed or deploying an airbag unexpectedly:
- Never cover, obstruct, or change the steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way.
- Never attach any objects such as cup
holders 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
moi5tened with plain water. Solvent5 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
ment parts designed and approved espe­
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 .
@ 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
chlorate. When the vehicle or parts of the restraint system including airbag modules
and safety belts with pretensioners are
scrapped, all applicable laws and regula­
tions must be observed. Your authorized
Audi dealer is familiar with these require­ ments and we recommend that you have
your dealer perform this service for you.

-Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
&
Maintenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impair
the function of the emission control
system and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is
operating properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the sulfur content of the fuel being used .
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline.
Diesel particulate filter
Ap plies to vehicles: with diesel partic ul ate filter
The diesel particulate filter filters nearly al l of
the soot part icles out of the exhaust. The fi l­
ter cleans itse lf automatically under normal
driving conditions . If the fi lter cannot clean it­
self (for example, because you are only driving
short distances), the filter becomes clogged
with soot and the
II symbol for the diesel
particulate filter illuminates
c> page 22.
A WARNING
- Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the diesel par­
t icu late filter could start a fire .
- Do not apply an underbody protectant in
the exhaust system a rea or a fire could
start.
(D Tip s
-When the diesel particulate filter be­
comes saturated, the engine speed in­
creases to approximate ly 1,500 rpm
while the vehicle is in motion to init iate
the cleaning of the diesel particulate fil­
ter a utomatically without the warning
l amp lighting up . If the warning lamp
Dri vin g and en vironm ent 171
Ill sti ll appears, you shou ld drive to a
qualified workshop .
Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low -lying parts such as spo ilers and exhaust
system parts do not bottom out and get dam­
aged.
This is espec ially true for veh icles with low­
slung chassis (sports chassis) and fully loaded
vehicles.
Operate your vehicle
economically and minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise Levels.
Fuel economy, env ironmenta l impact, and
wear on your eng ine, brakes and tires largely
depend on three facto rs:
- your personal driving style
- operating conditions
- technical limitations
If you ant ic ipate wha t you need to do next and
drive economically, you can easily cut your
fuel consumptio n by 10-15 percent . This sec­
tion wi ll give you some tips on how you can
help the env ironment and your pocketbook.
(D Tips
The consumption estimates as published
by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary depending upon vehi­
cle load and speed, road and weather con­
dit ions, trip length, etc.

172 Driving and en vironm ent
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
Avoid unnecessary accelerating and braking .
Vehicles use the most fuel when they are ac­
celerati ng. If you anticipate what is go ing to
happen next, you will need to brake less and,
thus , accelerate less . let the vehicle coast
whenever poss ible -fo r example whe n you see
th at the next traffic ligh t is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
,. Try and keep well be low your car's max i-
mum speed .
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
env ironment.
Fuel consumption, ex ha ust em issions and en­
g ine no ise increase d isproportiona tely at hig h
speeds . If you dr ive at approximately three
qua rters of top speed, fuel consumption will
be reduced by one ha lf . Never dr ive faster
tha n the posted speed limit a nd weather con­
d it ions permit.
Reducing unnecessary idling
E ven when your car is just idling it burns up
fuel.
,. Shut the engine off when you a re not dr iv­
ing the vehicle.
,. Do not warm up the veh icle by letting the
engi ne run at idle.
It makes sense to shut off the eng ine in traff ic
jams, when waiting for trai ns to pass at ra il­
road cros sings, or at t raffic ligh ts that have
l ong wa its on red. Turning the engine o ff fo r
just 30 -40 seconds saves more fue l than is
bu rne d starting the engine again.
It takes a long t ime for the engine to warm up
fully when it is running at id le . However, wea r
and noxious emissions are espec ia lly high
when the eng ine is wa rm ing up. So you shou ld
drive away as soon as yo u start the engine and
avo id running at high RPMs w hile the eng ine
i s s till warm ing up .
(D Note
Do not leave engine idling unattended af­
ter start ing . If warni ng lig hts sho uld come
o n t o indicate improper ope ration, they
would go unheeded . Extended idli ng also
produ ces heat , w hich could result in ove r­
hea ting or other dam age to the veh icle or
other property .
Regular maintenance
A badly tuned engine unne cessarily wastes a
lo t of fuel.
,. Have your ve hicle serviced at reg ular inter-
vals.
By havi ng your ve hicle regu larly serv iced by an
a utho rized Aud i deale r helps to ensure that it
runs properly and econom ica lly. The cond it io n
of your ve hicle not only affe cts i ts safety and
abili ty to ho ld i ts va lue , it al so a ffects
fuel
con sumption .
Check your oil each time you fill your tank .
The amount of oi l 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 certa in
mileage has bee n driven .
You must drive your vehicle about 3,000 mi les
(S,000 kilometers) before you can properly
assess oil consumpt ion.
T his also app lies to fue l cons umption and en­
gine o utp ut.

Gasoline additives
A majo r concern among ma ny auto manufac ­
turers is carbon deposit build -up caused by
the type of gasoline you use .
A lthough gasoline grades differ from one
manuf acturer to anothe r, they h ave certa in
things in common. All gaso line g rades contain
substances that can cause deposits to co llect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline
brands incl ude additives to keep engine and fuel systems clean, they a
re not equally effec­
tive .
A udi re commends using TOP TI ER De tergent
Gasoline. For mo re info rmat ion on TO P TI ER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadeq uate
