Deluxe automatic climate control
plus
App lies to veh icles: w ith De luxe automatic climate control plus
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 75 °F (+23 °C).
- Press the
[AUTO) button.
With this setting, you attain maximum comfort in the least amount
of time. Change this setting, as desired, to meet your personal needs.
Controls and equip­
ment Safety first
The climate controls are a combination
of heating, ventilation and
coo ling systems, which automatically red uce humidity and cool the
air inside your vehicle .
The climate control automatically maintains a temperature once it
has been set. The temperature of the air from the vents, fan speed
(air volume) and air distribution are also automatically adjusted. The
system a lso takes into account strong sunsh ine so that man ual
adjustment is not necessary. So in almost all cases,
automa tic mo de
offers the best condit ions for the comfort of the occupants at all
times of the year~
page 104.
Please note the following:
T urn on the a ir cond itioner 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,
condensati on 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 normally only switches to a
higher speed once the engine coolant has warmed up sufficiently.
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 coolant temperature is too
high, so that the engine can be adequately cooled under extreme
loads.
Du st a nd p ollen filt er
The dust and pollen filter (a combined particle fi lter and activated
charcoal filter) reduces or prevents outside a ir po llution (dust, or
pollen) from entering the vehicle.
T he dust and pollen filter must be changed at the intervals specified
in your Maintenance booklet, so that the air conditioner can properly
work.
If you drive your vehicle in an area with a high degree of air pollution,
the filter may need to be changed more frequently than specified in .,.

Repairs to the Audi a ir conditioner require special techn ica l knowl­
edge and special tools . Co ntact an a uth orized Audi dealer fo r assis­
tance .
(I] Tips
• To avoid adversely affecting heating and cooling performance and
to prevent condensation on the windows, the air intake in front of the
w indshield must be free of ice, snow and leaves.
• Th e air flowing out of the vents and througho ut the veh icle's
entire inter ior is discharged at the rea r of the vehicle . Make su re that
the o utlet s lots are not covered by clothing, etc.
• Climate control works most effective ly if the windows and the
panoramic sliding/tilt ing sunroof * are closed. However, if the interior
of a parked vehicle is extremely hot from the sun, briefly opening the
windows can speed up the cooling process. •

& WARNING (co ntinued )
• Always make sure that the side airbag can inflate without
interference:
-Never install se at covers or replacement upholstery over the
front seatbacks 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 airbag module must always be repaired immedi­
ately by an authorized Audi dealer.
• The airbag sy stem 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 sy st e m can be deployed only onc e. After an airbag
has been deployed, it must be replaced w ith new replacement
parts de signed and approved es pecially for your Audi model
version . Replacement of complete airbag systems or airbag
components must be performed by qualified workshops only.
Make sure that any airbag service action is entered in your Audi
Warranty
& Maintenance booklet under AIRBAG REPLACEMENT
RECORD.
• In accidents when an airbag is deployed, the vehicle battery
separates the alternator and the starter from the vehicle electrical
system for safety reason s with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circu it interrupter must only be
performed by a qualified dealer -risk of an a ccident!
- If the vehicle or the circu it interrupter is scrapped, all appli­
cable safety precautions must be followed .

Driving and environment
The catalytic converter is an effic ient ''clean-up" dev ice built into the
ex hau st system of the ve hicle. The c ata ly tic converter bu rns many of
the pollutants in the exhaust gas before they are released into the
atmosphere.
T he exclusive use of unleaded fuel is c rit ical ly import ant for the life of
the cata lytic converter and proper funct ioning of the eng ine.
& WARNING
• Do not park or operate the vehicle in areas where the hot
e xhaust system may come in contact with dry grass, brush, fuel
spill or other material which can cause a fi re.
• Do not apply additional undercoating or rustproofing on or
near the e xhaust man ifold , exhaust pipes , catalytic converte r or
heat shields . During driving, the substance used for undercoating
could overheat and cause a fire.
0 Note
• Be aware that j ust one tank filling with leaded fuel will already
seriously degrade the performance of the ca talytic conve rter.
• Do not exceed the correct engine oil level =>
page 279.
• Do not dr ive until the fuel tan k becomes complete ly empty . The
engine could misfire . Unburned fuel cou ld also get into the exha ust
system and th is cou ld cause the catalyt ic converter to overheat .
• Do not tu rn o ff the igni tion while t he vehi cle is moving.
• Do not contin ue to operate your vehicle under these conditions, as

overheat ing of the converter, requir ing its replacement.
• T o ass ure eff icient ope ra ti on of the Emiss ion Cont rol System:
- Have your vehicle maintained properly and in accordance with
the se rvice recommendations in your Wa rranty

<£> For the sake of the environment
Even when the Emiss ion Control System is operating p roperly, the
exhaust gas can have a s ulfur -like exhaust gas smell under some
operat ing states . This depends on the sulfur content of the fu el being
used. Using a different brand of fuel may help, or filling the tank with
lead -free supe r grade gasoline. •

Driving and environment
------------------------------------------------'
depending upon vehicle load and speed, road and weather conditions,
trip length, etc. •
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are accelerating .
-Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are accelerating. If you antici­
pate what is going to happen next, you will need to brake less and,
thus, accelerate less. Let the vehicle coast whenever possible - for
example when you see that the next traffic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
- Try and keep well below your car's maximum speed.
Accelerating gently reduces fuel consumption, engine wear, and does
not disturb the environment .
Fuel consumption, exhaust emissions and eng ine noise increase
disproportionately at high speeds . If you drive at approximately three
quarters of top speed, fuel consumption will be reduced by one half.
Never drive faster than the posted speed limit and weather condi­
tions permit. •
Reducin~ unnecessary idling
Even when your car is just idling it burns up fuel.
-Shut the engine off when you are not driving the vehic le .
- Do not warm up the vehicle by letting the engine run at
idle.
Controls and equip­ ment Safety first Vehicle operation It makes sense to shut off the engine in traffic jams, when waiting for
trains to pass at railroad crossings, 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 t ime for the engine to warm up fully when it is running
at idle. However, wear and noxious emissions are especia lly high
when the eng ine is warming up. So you should dr ive away as soon as
you start the engine and avoid running at high rpms while the engine
is still warming up.
0 Note
Do not leave engine idling unattended after starting . If warning
lights should come on to indicate improper operation, they would go
unheeded. Extended idling also produces heat, which could result in
overheat ing or other damage to the vehicle or other property. •
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel .
- Have your vehic le serviced at regular intervals .
By having your vehicle regularly serviced by an authorized Audi dealer
helps to ensure that it runs properly and economically . The condit ion
of your vehicle not on ly affects its safety and ability to hold its val ue,
it also affects fuel consumption.
Check your oil each time you fill your tank.
Th e amount of oil used is related 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 dr ive your veh icle about 3,000 miles (5,000 kilometers)
before you can properly assess oi l consumption .
Thi s also applies to fuel consumption and eng ine output.

0 Note
• Have your vehicle mainta ined properly and in accordance w ith the
service recommendations in your Warranty
& Maintenance booklet.
Lack of proper maintenance as well as improper use of the vehicle w ill
impair the function of the emission control system and could lead to
damage.
• Do not alter or remove any component of the Emission Control
System unless approved by the manufacturer.
• Do not a lter or remove any device, such as heat shields, switches,
ignition w ires, va lves, which are designed to protect your vehicle 's
Emission Control System and other important vehicle components .•
Fewer short trips
Fuel consumption will always be relatively high on short
trips .
-Try to avoid driving short distances with a cold engine.
The engine and catalytic converter have to reach their optimal oper­
ating temperature
to reduce fuel consumption and noxious emis ­
sions effectively.
Just after starting, a cold engine in a mid-size car only achieves a fuel economy of 6-8 miles per ga llon (30-40 l/100 km). After about a half
a mile, fuel economy climbs to 12 mpg (20 l/100 km). After about
2.5 miles (4 km), the engine is at its proper operating temperature
and fuel economy has reached a normal level. So you can see that you
sho uld avoid short trips whenever poss ible.
The
outside temperature is also cr it ical in this regard . Your car
consumes more fue l in the winter than in the summer.
