Warm and cold
Climate controls
Description
A pplies to vehicles: with three-zone cl imate cont ro l or
four-zone a uto mat ic climate contro l
The climate control system warms, cools and
adds humidity to the air in the vehicle interior. It is the most effective when the windows and
sunroof* are closed .
If the temperature inside
the parked veh icle becomes very warm, open ­
ing the w indow br iefly will speed up the cool­
ing process.
In all heating mode functions except
defrost,
the blower on ly switches to a highe r speed
once the engine coolant has reached a certain
temperature.
Condensat ion from the cooling system can
d rip and form a puddle of wate r under the ve­
h icle. This is normal and does not mean there
is a leak .
Pollutant filt er
The pollutant filter removes pollutants such
as dust and po llen from the air.
The air pollutants filter must be changed at
the intervals spec ified in your Warranty
&
Maintenance booklet, so that the air condi­
tioner can properly work .
If you drive your vehicle in an area with high
a ir pollution, the filter may need to be
changed more freq uently than specified in
your Aud i Warranty & Ma intenance booklet. If
i n doubt, as k your author ized Audi Se rvice Ad­
visor for adv ice.
K ey coded setting s
Three-zone climate control: The blower set­
ting and air distribution are stored automati­
cally and assigned to the remote control key
that is in use.
Four-zone automatic climate control: The cli­
mate control settings are automatica lly stor­
ed and assigned to the remote control key
that is in use.
A 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
densat ion .
- Comp lete ly fami liarize yourse lf with the
proper use and funct ion of the heat ing
and ventilation system and especially
how to defog and defrost the w indows.
- Never use the windshield wiper/washer system in freez ing weather unt il you
have wa rmed the windshie ld first, using
the heating and ventilation system. The
washer sol ution may freeze on the w ind­
shie ld and red uce visib ility.
(D Note
- If you suspect that the air conditioner
has been damaged, switch the system
off to avoid further d amage and have i t
inspected by a q uali fied dealership .
- Repairs to the Audi air conditioner re­
quire speci al technical know ledge and
special tools. Contact an authorized Audi
dea ler fo r ass istance.
@ For the sake of the environment
By reducing the amount of f uel you use,
you also red uce the amount of pollutants
emitted into the air.
(D Tips
- Keep the air intake s lo ts (in front o f the
windshield) free from ice, snow and de ­
bris in order to maintain the proper func­
tion of the climate control system.
- The energy management system may
switch the seat heating* or rear window
defroster off temporar ily. These systems
are available again as soon as the energy
balance has been restored .
-Air escapes through vents under the rear
w indow. When plac ing items of cloth ing
on the luggage compartment cover, en­
sure that the openings are not covered.

-Have the airbag system inspected by
your Audi dealer before transporting
anyone on the front passenger seat.
(D Tips
If the capacitive passenger detection sys­
tem determines that the front passenger
seat is empty, the frontal airbag on the
passenger side will be turned off, and the
PASSENGER AIR BAG OFF light will stay
on .
Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places on your Audi. Installing,
removing, servicing or repairing a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
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.
A 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
moistened with plain water. Solvents 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.
Airbag system 161
- 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 deploy only once .
After an airbag has been deployed, it
must be replaced with new replacement
parts designed and approved especially
for your Audi model version. Replace­ ment of complete airbag systems or air­
bag components must be performed by
qualified workshops only. Make sure that
any airbag service action is entered in
your Audi Warranty
& Maintenance book­
let under
AIRBAG REPLACEMENT RE­
CORD .
-For safety reasons in severe accidents,
the alternator and starter are separated
from the vehicle battery with a pyrotech­
nic circuit interrupter.
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a
qualified technicians who have the ...

@ Tips
-ABS and ASR on ly work correctly when
all four wheels are equipped w ith identi­
cal tires. Different tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems
described are working.
- If the indicator light
DJ or 11:11 (USA

The following examples are unusual situa­
tions where it may make sense to switch sport
mode on in order to allow the wheels to spin:
- Rocking the vehicle back and forth when it is
stuck
- Driving in deep snow or on loose ground
- Driving with snow cha ins
Switching sport mode off
Press the 1.$ OF FI button again. The I indica­

A WARNING
-
-Drive wheels can spin and you can lose
control of the vehicle more easily when
ASR and ESC are in sport mode, especial­
ly when the road is slippery.
- Sw itch to sport mode only when your
driving skills, traffic and weather condi­
tions permit.
@ Tips
You cannot sw itch sport mode on when
adaptive cruise control* is working.
Braking
General information
What affects braking efficiency?
-
Operating conditions and driving habits
The brakes on today's automobiles are still
subject to wear, depending largely on operat­
ing condit ions and driving hab its
c::> .&. . On
vehicles that are either driven most ly in stop­
and-go city t raff ic or are driven hard, the
brake pads should be checked by your author­
ized Audi dea ler more often than specified in
the
Warranty & Maintenance booklet. Failure
to have your brake pads inspected can result
in reduced brake performance .
On steep slopes, you should use the braking
effect of the engine . This way, you prevent un­
necessary wear on the brake system. If you
must use your brakes, do not hold the brakes
down continuously. Pump the brakes at inter­
vals .
Moisture o r road salt
Under certain conditions, for example, when
driving through water or very heavy rain, or
even after washing your vehicle, the braking
effect can be reduced due to moisture (or in .,,_

200 Driving and en vir onm ent
Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner .
• Always use lead-free gasoline¢ page 220,
Fuel supply.
• Never run the tank down all the way to
empty .
• Never put too much motor oil in your en-
gine ¢
page 230, Adding engine oil~-
., Never try to push- or tow -start your veh icle.
The catalytic converter is an eff ic ient "clean­
up" device built into the exhaust system of
the vehicle. The catalytic converter burns many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critically
important for the life of the cata lytic conve rt­
e r and proper functioning of the engine.
& WARNING
-
- Do not park o r operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold, exhaust p ipes, catalytic con­
verter or heat shields . During driving, the
substance used for undercoating could
overheat and cause a fire .
@ Note
-Be aware that just one tank filling with
leaded fuel will already seriously de­
grade the performance of the catalytic
conve rter .
- Do not exceed the correct engine oil level
¢ page 230.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis­
fire . U nburned f uel could a lso get into the exhaust system and this co
uld cause
the cata lytic converter to overheat .
- Do not switch off the ignition while the
vehicle is moving .
- Do not continue to ope rate your veh icle
under these conditions, as otherwise fuel
can reach the catalytic converter. This
cou ld result in overheating of the con­
verter, requir ing its replacement.
- To assure efficient operation of the Emis ­
sion Control System:
- H ave your vehicle maintained properly
and in accordance w it h the service rec­
ommendat ions in your Warranty &
M ain tenance book let.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle will impair
the function of the em iss ion contro l
system and could lead to damage .
@ For the sake of the environment
Even when the Emiss ion Control System is
operat ing proper ly, the exha ust gas can
have a sul fur -li ke exhaust gas smell under
some operating states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or f il li ng the tank with lead-free super
grade gasoline .
Avoid damaging the
vehicle
When you are d rivi ng on poor roads, or over
c u rbs, steep ramps, etc., ma ke certai n that
low- ly ing parts s uch as spoilers and exha ust
system parts do not bottom o ut and get dam ­
aged.
T his is espe cially true for ve hicles with low­
s lung chassis (spor ts chassis)* and fully load­
ed vehicles .

202 Driving and environment
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
.,. Try and keep well below your car's maxi-
mum speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment.
Fu el consumption, exhaust emissions and en ­
gine 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 con­
ditions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
.,. Shut the engine off when you are not driv­
ing the vehicle .
... Do not warm up the veh icle by letting the
engine run at idle .
The idling phase is automat ically reduced for
vehicles w ith the Start/Stop system .
It is effi ­
cient to switch
off the engine in vehicles with­
out the Start-Stop-System when stopped at
railroad crossings and long red lights . Turning
the engine
off for just 30-40 seconds saves
more f uel than is burned by starting the en­
gine again.
It takes a long time for the engine to wa rm 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.
([) Note
Do not leave engine idling unattended af­
ter starting. If warning lights should come
on to indicate improper operation, they would
go unheeded. Extended idling also
produces heat, which could result in over­
heating or other damage to the veh icle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
.,. Have your vehicle serviced at regu la r inter-
vals .
By having your veh icle reg ularly se rviced by an
Audi dealer he lps to ensure that it runs prop­
erly and economically. The condition of your
vehicle not only affects its safety and ability to
ho ld its value, it also affects
fuel consump ­
tion .
Check your oil each time you fill your tank.
The amou nt of oi l 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 drive your veh icle about 3,000 miles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fuel 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
tenance booklet. Lack of proper ma inte­
nance as well as improper use of the ve­
hicle will impair the function of the
em ission control system and could lead
to damage.
- Do not alter or remove any component of
t he 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

206 Trailer towing
Always apply brakes early. When driving
downhill, shift into a lower gear to use the en­
g ine braking effect to slow the vehicle . Use of
the brakes alone can cause them to overheat
and fail.
Coolant temperature
The coolant temperature gauge¢ page 11
must be observed carefully. The coolant tem­
perature can increase if you drive on long in­
clines in a low gear at high engine speeds. Re­
duce your speed immediately if the LEDs in
the top part of the display turn on .
For more information about indicator lights,
refer to. ¢
page 16 .
A WARNING
Anyone not properly restrained in a mov­
ing vehicle is at a much greater risk in an
accident . Never let anyone r ide in your car
who is not properly wear ing the restraints
provided by Aud i.
Trailer towing tips
Important to know
Your vehicle handles differently when towing
a trailer because of the additional weight and
different weight distribution . Safety, perform­
ance and economy w ill greatly depend on how
carefully you load your trailer and operate
your rig .
Before you actually tow your trailer, practice
turn ing, stopp ing and back ing up in an area
away from traffic. Keep practicing until you
have become comp lete ly familiar with the way
your ve hicle-trai ler comb ination behaves and
responds.
Backing up is difficult and requires practice .
Backing up with a tra iler generally requi res
steering act ion opposite to that when backing
up your vehicle without a trailer.
Maintain a greater distance between your ve­
hicle and the one in front of you. You will need
more room to stop. To compensate for the trailer, you wi
ll need a larger than normal
turning radius.
When passing, remember that you cannot ac­
celerate as fast as you norma lly would be­
cause of the added load. Make sure you have
enough room to pass . After passing, a llow
plenty of room for your trailer before chang ­
ing lanes again.
Avoid jerky starts , sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the extra load¢
page 285.
Parking on a slope
Do not park on o slope with a trailer. If it can­
not be avoided, do so only after doing the fol­
lowing:
When parking:
.,. App ly the foot brake .
.. Have someone pla ce chocks under both the
vehicle and the trailer wheels.
.. With chocks in place, slowly release the
brakes until the whee l chocks absorb the
load .
.. Turn the wheels towards the curb .
.. Apply the parking brake.
.. Select the P selector lever posit ion .
When restarting after parking:
.. Apply the foot brake.
.. Start the engine.
.. Select the D/S selector lever position .
.. Release the parking brake and slowly pull
out and away from the wheel chocks .
.,. Stop and have someone retr ieve the wheel
chocks .
Ill-
