Climate controls
Description
The air conditioner is fully automatic and is designed to
maintain a comfortable and uniform climate inside the
vehicle.
We recomme nd the following s ettings:
- Select and set a temperature between 64
°F (+22 °C) and
84 °F (+28 °C).
- Press the !AUTO
I button.
With this setting, you attain maximum comfort in the least amount
of time . Change this set ting, as desired, to mee t your pe rsonal
needs.
The climate controls are a combination of heating, venti lation and
cooling systems, which automatica lly reduce humidity and coo l the
air inside your vehic le .
The air temperature, air flow and air distribution are automatically
regu lated to achieve and maintain the desired passenger compart ­
ment temperature as quick ly as possible.
The system automatically compensates for changes in the outside
temperature and for the intensity of the sun light entering the
vehic le. We recomme nd you use the
Automati c mode~ page 99for
year -round comfort.
P lease note the following :
Turn on the air conditioner to reduce humidity in the vehic le. This
a lso prevent the window s from fogging up. When the outside temperature is high and the air is very humid,
c
ondensat ion from the evaporator may drip under the vehicle . T his
is normal and does not indicate a leak.
I f the outside temperature is low, the fan normally only switches to
a higher speed once the engine coola nt has war med u p sufficiently .
T he air conditioner temporarily sw itches off when you drive off from
a standstill using fu ll throttle to save engine power.
The comp ressor also swi tches off if the coolant temperatu re is to o
high so that the engine can be adequate ly cooled under extreme
lo ads .
Air pollutants filt er
The air po llutants fi lter (a combined partic le filter and activated
charcoal fi lter) reduces or eliminates outside air pollution (dust, or
p ollen) from en ter ing the vehic le .
The air po llutants fi lter must be changed at the intervals specified
in your Warranty
& Maintenance bo oklet, so that the ai r conditioner
can proper ly work.
I f you drive your vehicle in an area with high air pol lution, the filter
may need to be changed m ore freque ntly tha n specified in your
Audi Warranty
& Maintenance booklet. If in doubt, ask your autho­
r iz ed Aud i Service Adviso r fo r a dvice .
& WARNING
Redu ced vi sibility i s dangerou s and can cause accidents .
• For saf e driving it is very important that all window s be free of
ice , sno w and conden sation.
• Fully familiarize yourself with the proper use and fun ction of
the heating and ventil ation sy stem and especially how to defog
and defrost the windows. ...

& WARN ING (continued )
• Always make sure that the side airbag can inflate without inter­
fe rence :
- Never install seat covers or replacement upholstery over the
front seatback s that have not been spe cifically 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 system can be activated only once. After an airbag
ha s inflated , it must be replaced by an authorized Audi de aler 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 repla ced with new repla cement
parts designed and approved especially 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

Other things that can affect Advanced Airbag
performance
Changing the vehic le's suspension system can change the way that
th e Adva nced A ir b ag Sy stem per fo rms in a cras h. For exa m ple,
using tire -rim combinations not approved by Audi, lowering the
vehic le, c hanging the st iff ne ss of th e susp ens ion , incl udi ng the
spr ings, suspension struts, s hock absorbers etc . ca n chan ge the
forces that are mea su red by the air bag sensors and sent to the elec ­
tronic control unit. Some suspension chan ges can, for examp le, increase the force levels
measured by the sensors and make the
airbag sys te m d eploy in c ras hes i n wh ich i t wou ld not d epl oy i f the
changes had not been made. Other kinds of changes may reduce
t he fo rce level s measu red by the se nso rs and p reve nt the ai rbag
from dep loying when it should.
T he sensors in the safety belt buckle for the driver and front
p assenge r seat te ll the e lectro nic c ont ro l m odu le if th e safety belt is
l atched or not. If the safety belt is being used, the front airbag wi ll
d eploy at a sl igh tly higher rate o f ve hic le dece lera tio n th an if the
safety be lt is not be ing used. Therefore, in a particular coll ision, it is
p os sible that an airbag wi ll no t de ploy a t a seating position where
the safety be lt is being used but wi ll inflate at the position where the
safe ty be lt is not be ing used . It i s important tha t n othing in terfe re

i nfo rma tion abo ut safe ty belt use to the elec tro nic con trol u nit .
& WARNING
Changing the vehicle' s suspension including use of unapproved
tire -rim combinations can change Advanced Airbag performan ce
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 originally
installed on your vehi cle .
• Never use tire -rim combinations that have not been approved
by Audi.
& WARNING
Items stored between the safety belt buckle and the center
console can cause the sensors in the buckle to send the wrong
information to the electronic control module and prevent the
Advanced Airbag System from working properly .
• Always make sure that noth ing can interfere w ith the safety
belt buckles and that they are not obstructed.

The exclusive use of unleaded fuel is critically important for the life
of the catalytic converter and proper functioning of the engine.
& WARNING
• Do not park or 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 manifold, exhaust pipes, catalytic converter or
heat shields . During driving, the substance used for undercoating
could overheat and cause a fire.
0 Note
• Be aware that just one tank filling with leaded fuel will already
seriously degrade the performance of the catalytic converter.
• Do not exceed the correct engine oil level~
page 230.
• Do not drive until the fuel tank becomes completely empty. The
engine could misfire. Unburned fuel could also get into the exhaust
system and this could cause the catalytic converter to overheat.
• Do not turn off the ignition while the vehicle is moving.
• Do not continue to operate your vehicle under these conditions,
as otherwise fuel can reach the catalytic converter. This could result
in overheating of the converter, requiring its replacement.
• To assure efficient operation of the Emission Control System :
- Have your vehicle maintained properly and in accordance with
the service recommendations 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.
Controls and equip­ ment Safety first Vehicle operation
Driving and environment
<£' 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 with lead-free super grade gasoline. •
Applies to veh ic les : with diesel particulate filter
Diesel particu ate filter
The diesel particulate filter filters nearly all of the soot particles out
of the exhaust. The filter cleans itself automatically under normal
driving conditions. If the filter cannot clean itself (for example,
because you are only driving short distances), the filter becomes
clogged with soot and the symbol for the diesel particulate filter
illuminates ~
page 32.
& WARNING
• Do not park your vehicle over flammable materials such as
grass or leaves because the high temperature of the diesel partic­
ulate filter could start a fire.
• Do not apply an underbody protectant in the exhaust system
area or a fire could start.
[ i] Tips
• When the diesel particulate filter becomes saturated, the engine
speed increases to approximately 1,500 rpm while the vehicle is in
motion to initiate the cleaning of the diesel particulate filter auto­
matically without the warning lamp lighting up. If the warning lamp
still appears, you should drive to a qualified workshop. •

long waits on red. Turning the engine off for just 30 -40 seconds
saves more f ue l than i s bu rned star ting 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 em issions are especial ly
h ig h w hen the eng ine is warming up. So y ou should dr ive away as
soon as you start the engine and avoid running at high RPMs whi le
the eng ine is still warming up.
0 Note
Do not leave en gine idling unattended after starting. If warn ing
lights should come on to indicate improper operation, they would
go unheeded . Extended idling also produces heat, wh ich cou ld
result in overheating or other damage to the vehicle or other
property .
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
- Have your vehicle serviced at regu lar intervals.
By having your vehicle regu lar ly serviced by an authorized Audi
dea ler he lps to ensure that it runs properly and econo mically . The
condition of your vehicle not only affects its safety and abi lity to
hold i ts va lue, it a lso affects fuel consumpt ion .
Che ck yo ur oil ea ch t ime you fill your t ank.
T he amount of oil used is related to engine load and speed.
It is nor mal for the oil consumption of a new engine to reach its
lowest va lue after a certain mi leage has been driven.
You must drive your vehicle about 3,000 mi les (5,000 kilometers)
before you can proper ly assess oil consumption .

Fewer short trips
Fuel consump tion will always be relatively hi gh on shor t
trips.
- Try to avo id driving short dista nces wi th a cold en gine.
The engine and cata lytic c onverter have to reach their optima l oper ­
ating temperature to reduce fuel consumption and noxious emis ­
sions effective ly .
• Just after starting, a cold engine in a mid-size car burns the fuel
at a poor rate of 6 -8 miles per gallon (30 -40 11100km). Half a mi le
down the road, the mileage improves to 12 MPG (20 1/100 km). It wi ll
take the engine no less than
two and a half miles (4 km) of driving to
warm up to its proper operat ing temperature and operate at a n
economic mileage . This exp lains why taking the car for short trips is
a ra ther waste ful convenience .
• The outs ide temperat ure is also critical in this regard. Your car
consumes more fuel in the winter than in the summer .•

The engine oil used in your Audi needs the right kind of
oil.
The engine in your Audi is a sophisticated powerp lant that was built
to exacting specifications. This engine needs the right kind of
engine oil that meets specifications rega rding quality and viscosity
so that it can run smoothly and reliably. Choosing the right oil and
changing oil within the time and mileage intervals printed in your
vehic le's Warranty
& Maintenance booklet matters a lot more today
than it did years ago. Audi has developed a special quality standard
for engine oi l that will help assure that your vehicle's engine will get
the lubrication it needs for proper operation.
Modern engine lubrication has taken a quantum leap in the last few
years. Many synthetic oils available today provide better engine
lubrication that can outlast traditional petroleum -based oils,
making them a smart choice for use throughout the life of your Audi.
Whether you use synthetic or petroleum -based engine oil, the oil
that you use must conform to Audi's oi l quality standard VW 502 00
(vehicles with gasoline engine) and VW 507 00 (vehicle with diesel
engine) to help keep your vehicle's engine running smoo thly and _,..

help prevent the formation of harmful deposits, sometimes called
"s ludge," that over time can lead to expensive repairs.
At the time of printing, engine oi ls available in the U .S . and Canada
that meet the exacting specifications of Audi oil standard VW 502 00
(vehicles with gasoline engine) and VW 507 00 (vehicles with diesel
engine) are synthetic engine oils. This does not mean, however, that
every synthe tic engine oil wi ll meet Audi o il standard VW 502 00
(gasoline engines) and VW 507 00 (diesel engines). So always be
sure that you use an approved oil.
To help p reve nt th e for matio n of ha rmful d epo sit s use only oil wit h
the following sp ecific ati ons print ed on th e oil contain er:
• Gas oline engine s: Audi oil sta ndard VW 502 00
• Dies el en gin es: Aud i oil stand ard VW 507 00
O il container labels may carry the speci fication singly or in combi­
nation with other designations and oil qua lity standards.
Vi sc osity
Engine o ils are graded according to their viscosity. The proper
viscosity grade oil for your engine depends on climactic or seasona l
conditions where you drive . You can use o il with a v iscosity grade o f
SAE 5W-40 across all temperature ranges for normal driving condi­
tions.
However, if engine oil viscosity grade SAE 5W-40 is not avai lab le,
you can also use viscosity grade SAE 5W -30 or SAE 0W -40 as long as
it meets Audi oil quality standard VW 502 00 (vehicles with gaso line
engine) or VW 507 00 (vehicles with diesel engine) specifications.
Because engine oil that meets the Aud i o il standard may not be
avai lable everywhere when you need it, we strong ly recommend
that you a lways carry with you an extra quart (liter) of oil that
expressly conforms to the VW 502 00 (vehic les with gaso line engine)
or VW 507 00 (vehicles with diesel engine) specification, in case you
have to top off the oil while on the road.
Ap plie s to veh icles with g asoline eng ine onl y: Only if the level of the
oi l is at or below the min imum mark on the oil dipstick -and no oil that expressly conforms to Audi oi
l standard VW 502 00 specifica ­
tions is availab le -may you top off with a high quality e ngine oi l,
preferably synthetic-based, that meets ACEA A3, ACEA A5 or
ACEA 85 or AP I SL specifications, but even then, on ly in viscos ity
grades SAE 5W-40, SAE 5W -30, or SAE 0W-40. However, during the
entire time between oil change intervals, never top off with more
than a total of 0.5 qt/liter engine oil that does not con form to Audi
oi l specification VW 502 00 .
Applies to veh icle s with die sel eng ine only: Only if the level of the
oi l is at or below the minimum mark on the oi l dipstick -and no oil
that expressly confo rms to Aud i oi l standard VW 507 00 specifica ­
tions is available -may you top off with a high quality engine oil, that
meets ACEA C3 or API CF specifications, but even then, only in
v iscosity grades SAE 5W -40, SAE 5W -30 , or SAE 0W-40. However,
during the entire time between oi l change interva ls, never top off
with more than a total of 0.5 qt/liter engine oil that does not conform to Audi oil specification VW 507 00.
For more information abo ut engine oi l that has been app roved for
your vehicle, p lease contact either your authorized Audi dea ler or
Audi Custo mer Relations at 1 (800) 822 -2834 or visit our web site at
www.audiusa.com or www.audicanada.ca . Here you will a lso find a
current list of oils (manufacturers, brand names etc.) that conform
to Audi oi l standard VW 502 00 (vehicles with gaso line engine) or
VW 507 00 (vehicles with diese l engine) .
Changin g the engine oil
The engine oil and oil filter must be changed according to the
mi leage (ki lometers) and time in tervals specified in your vehic le's
Warranty
& Maintenance book let. Do not exceed these intervals -
harmful deposits from old engine oil can reduce engine perfor ­
mance and can lead to expensive engine repairs.
Changing the oil at the recommended intervals is so very important
because the lub ricating prope rties of oi l decrease gradua lly during
normal vehicle use . If you are not sure when you have your oil
changed, ask your authorized Audi Service Advisor . ..,.
Vehicle care I t •

-~_C_ h_e _c _ k_ i_n ...:::g::;...._ a_n_ d_ f_ i_ll _in -'g:::;.._ ___________________________________________ _
Under some circumstances the engine oil should even be changed
more frequently. Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or mostly under stop ­
and -go traffic conditions, or when you use your vehicle where
temperatures stay below freezing point for long periods .
Detergent additives in the oil will make fresh oil look dark after the
engine has been running for a short time. This is normal and is not
a reason to change the oil more often than recommended .
Damage or malfunctions due to lack of maintenance
It is essential that you change your oi l at the recommended intervals
using only engine oil that complies with Audi oil standard
VW 502 00 (vehicles with gasoline engine) or VW 507 00 (vehicles
with diesel engine). Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure to follow recom­
mended maintenance and use requirements as set forth in the Audi
Owner's Manual and Warranty
& Maintenance booklet. Your dealer
will have to deny warranty coverage unless you present to the dealer proof in the form of Service or Repair Orders that all scheduled
maintenance was performed in a timely manner .•
Engine oil consumption
The engine in your vehicle depends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to provide effective lubrication and cooling of interna l
engine components, all internal combustion engines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change significant ly over the life of the engine. Typically,
engines with a specified break -in period (see=>
page 195) consume
more oil during the break-in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil consumption depends on
the quality and viscosity of the oil, the RPM (revolutions per minute)
at which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oil dilution from water condensation or fuel residue and the oxidation level of the oil. As
any
engine is subject to wear as mileage builds up, the oil consump­
tion may increase over time until replacement of worn components
may become necessary .
With all these variables coming into play, no standard rate of oi l
consumption can be established or specified. There is no alternative
to regular and frequent checking of the oil level, see
Note.
If the yellow engine oil level warning symbol in the instrument
cluster lights up, you should check the oil level as soon as
possible
with the oil dipstick=> page 229. Top off the oi l at your
earliest convenience =>
page 230.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS
=> &. in "Work ing in the engine
compartment" on
page 224.
0 Note
Driving with an insufficient oil level is likely to cause severe damage
to the engine.
[ i ] Tips
• The oil pressure warning display~ is not an indicator of the oil
level. Do not rely on it. Instead, check the oil level in your engine at
regular intervals , preferably each time you refuel, and always before
going on a long trip.
• If you have the impression your engine consumes excessive
amounts of oil, we recommend that you consu lt your authorized
Audi dealer to have the cause of your concern properly diagnosed .
Keep in mind that the accurate measurement of oil consumption
requires great care and may take some time. Your authorized Audi
dealer has instructions about how to measure oil consumption
accurately. •
