If the symbol lights up, even when there is ample fue l in the tank, and
the text
Tank system malfunction! Please contact workshop appears
in the display, there is a fault in the system. Contact a qualified work­
shop to have the fault rectified .•

Th e eng ine speed is limited to the speed displayed in the driver infor­
mation system. Keep in mind that the engine speed will not exceed
the value disp layed in the driver information system, for example
when downshifting .
Please go to an authorized Audi dealer or other qualified workshop to
have the malfunction repai red. •
App lies to vehicles: with diesel eng ine and diesel particulate filter
Diesel particulate filter clogged
Particulate filter ! See owner's manual
If the indicato r light in the instrum ent cluster comes on, the
diesel particulate filter has become blocked with soot as the result of
constant short -distance driving. When the symbol illuminates,
you can alter your driving style to assist the filter self-cleaning
process. Drive for approximately 15 minutes in 4th or 5th gear (auto­
matic transm ission w ith the selector lever in the 5 posit ion) at a min
imum speed of 37 mph (60 km/h) and an engine speed of approx­
imate ly 2,000 RPM. The temperature increase that will result from
this can burn off the soot in the f ilter. The symbol will switch off when
the cleaning is successful. After a successfu l cleaning, there is no
need to bring the car to an authorized dealer or qualified workshop
because this is part of normal vehicle operation.
If the symbol does not switch off, see your authorized dealer or
other qualified workshop to have the problem corrected.
As long as the indicator light remains on (diese l particulate filter
plugged), you can expect increased fuel consumption and poss ibly
also a loss of engine performance.
For more information on the diesel particulate filter, refer to
=;, page 199.
& WARNING
Always adapt your speed to the current weather, road and traffic
conditions . You should never disobey traffic laws in order to
follow driving recommendations. •

Roof rack* installation
First things first
A roof rack can be used to carry additional luggage on the
roof There are two different roof rack systems.
Separate roof racks are needed for vehicles without roof rails.
Vehicles with standard roof rails* need additional cross bars
to carry cargo. Both types of additional equipment are avail­
able at your authorized Audi dealer.
- Always read and follow th e instructions provided by the
roof rack manufacturer when the roof rack system must
be installed.
If a roof rack or similar luggage carrying equipment is to be installed,
please note the following:
Vehicles without roof rails
• Your vehicle has aerodynamic rain gutters molded into the roof.
Th at is why only roof racks specially designed for the roof can be used. We recommend using roof racks from the Audi orig
inal accessories
program.
• These roof racks are the basis for a complete roof rack system. For
safety reasons, some additional attachments are necessary to trans­
port luggage, bicycles, surf boards, skis and small boats safely. All
these components are available at your author ized Audi dealer.
Vehicle with roof rails
• The vehicle is equ ipped with integrated roof railings, which can be
covered into roof rack by installing cross bars. Only install cross bars
specifically designed for this vehicle.
• These bars are the basis for a complete roof rack system. Addi­
tional attachments are necessary to safely transport luggage, bicy­
cles, surf boards, skis or small boats.
• All necessary hardware for these systems is available from your
authorized Audi dealer.
When should the roof rack be removed?
• Before going through an automatic car wash (it is best to ask the
car wash operator)
• When not in use (reduce fuel consumption, reduce wind noise and
guard against theft)
& WARNING
• Use of an unapproved roof rack or incorrect mounting of an
approved roof rack can cause the roof rack or the items carried on
it to fall off the roof onto the road .
• Objects falling from the roof of a vehicle can cause a crash and
personal injury.
• Only mount the system between the markings shown in
=> page 87, fig . 88 or=> page 88, fig . 89.
• The roof rack system must be installed exactly according to the
in structions provided . .,_

Fig. 102 Instrument panel: air outlet locations and airflow directions
The air outlets (D and @on top of the instrument panel are
fixed. Outlets ® and © can be adjusted.
Adjusting air outlets ® and ©
-Turn the vertical thumbwheel beside the outlet to
increase, reduce or shut down the airflow from that
outlet.
- Move the small tab in the center of the outlet louver side­
ways and up or down to adjust the level and direction of
airflow .
Contro ls a nd e quip ­

OP-eration
The supply of a ir to the outlets is controlled either automat ically or
manually depend ing on the operation mode selected. The airflow
from all outlets can be heated, unheated or cooled .
The heater outlets for the rear footwells are located under the front
seats. When you select outlets@, air is also directed to the rear foot­
wells.
[I) Tips
• When defrosting/defogging the windows, air flows from outlets
(D ,@ and @. To defrost or defog the windows as rapidly as poss ible,
air outlets ® should be opened
fully with the adjuster wheels.
• When the air conditioner is working, cooled air w ill flow primarily
from outlets @,® and @. To assure adequate cooling, outlets ®
and © should never be completely closed.•
Using the climate controls economically
Using the climate controls prudently can help save fuel .
When you use the air conditioner, engine power is reduced
and fuel consumption increases. To save fuel, you should use
the air conditioner only when necessary. Also please note the
following points:
- If you want to save fuel, switch off the air conditioner .
- If you are going to drive with the windows open, switch off
the air conditioner.
By reducing the amount of fuel you use, you also reduce the amount
of polluta nts emitted into the air. •

Driving and environment
This is especially true for vehicles 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 exhaust and noise levels.
Fuel economy, env ironmental impact, and wear on your eng ine,
brakes and tires largely depend on three factors:
• your personal driving style
• operat ing conditions
• technical lim itations
If you anticipate what you need to do next and drive economically,
you can easily cut your fuel consumpt ion by 10-15 percent. This
sect ion wi ll g ive you some tips on how you can help the environment
and your pocketbook.
[I) Tips
The consumption estimates as published by ENVIRONMENTAL PROTECTION AGENCY (EPA) and Transport Canada may not co rre­
spond to your actual consumption on the road, which will vary
depending upon vehicle load and speed, road and weather conditions,
trip length, etc. •
Drive smoothl} 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 go ing 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 d isturb the env ironment.
Fuel consumption, exhaust emissions and engine 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 perm it. •
Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
- Shut the engine off when you are not driving the vehicle .
- 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 railroad crossings, or at traffic lights that have long
wa its on red. Turn ing the eng ine 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 espec ially high
when the engine is warming up . So you shou ld drive away as soon as .,_

Driving and environment
------------------------------------------------'
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 vehicle 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 condition
of your vehicle not on ly affects its safety and ability to hold its value,
it also affects
fuel consumption .
Check your oil each time you fill your tank.
The 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 mi leage has been driven.
You must drive you r vehicle about 3,000 miles (5,000 kilometers)
before you can properly assess oil consumption.
Thi s also applies to fuel consumption and engine output.
0 Note
• 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
impa ir the function of the emission control system and could lead to
damage.
Controls and equip­ ment Safety first Vehicle operation
•
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 shie lds, switches,
ignition w ires, va lves, which are designed to protect your vehicle 's
Emission Control System and other important vehicle components.
Fewer short tr ips
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 eng ine in a mid-size car burns the fuel at
a poor rate of 6-8 miles per gallon (30-40 l/l00km). Half a mile down
the road, the mileage improves to 12 MPG (20 l/100 km). It will 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 an
economic mileage . This explains why taking the car for sho rt trips is a
rather wasteful convenience .
• Th e
outside temperature is also critical in this regard . Your car
consumes more fuel in the winter than in the summer.

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 traff ic conditions, or when you use your vehicle where temper­
atures stay below freezing point for long periods .
Detergent additives in the oil will make fresh oil look dark after the
engine has been run ning 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 essentia l that you change your oi l at the recommended intervals
using only engine oil that complies with Audi oi l 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 recommended maintenance
and use requirements as set forth in the Audi Owner's Manua l 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 internal
engine components, all internal combustion engines consume a
certain amount of o il. Oil consumpt ion varies from engine to engine
and may change significant ly over the life of the eng ine. Typically,
engines with a specified break- in period (see~
page 197) consume
more oi l during the break-in period than they cons ume after oil
consumption has stabilized.
Under normal cond itions, the rate of oil consumpt ion depends on the
quality and vis cosity of the oil, the RPM (revol utions pe r minute) at
which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oi l dilution from water condensation or fuel residue and the ox
idation level of the o il. As any
eng ine is subject to wear as mileage builds up, the oil consumption
may increase over time until replacement of worn components may
become necessary.
With all these variab les coming into play, no standard rate of oil
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
cl uster .... lights up, you should check the oil level as soon as possible
with the oil dipstick~ page 231. Top off the o il at your earliest
convenience ~
page 232.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS~
& in "Work ing in the engine
compartment" on
page 226.
0 Note
Driving with an insufficient oil level is likely to cause severe damage
to the engine .
[ i ] Tips
• The oil pressure warning display 't::r. 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 alway s
before going on a long trip.
• If you have the impression your eng ine consumes excessive
amounts of oi l, we recommend that you consu lt your authorized Audi
dea ler 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 dea le r has
instructions about how to measure oil consumption accurately. •

engine run at idle and then shut it off.
- Wait approx . two minutes.
Vehicle OP-eration
-Pull out the oil dipstick. Wipe off the oil dipstick with a
clean cloth, and slide it back in as far as it will go.
- Pull it back out and read off the oil level~ fig. 163 or
~ fig. 164. Top off the engine oil, if applicable
~ page 232 .
Oil level w ithin range @
- Do not add oil.
Oil level within range®
- You can add oil. A~erwards, the oil level should be within
range @.
Oil level within range ©
-You must add oil. A~erwards, the oil level should be
within range @.
The oil level needs to be checked at regular intervals. The best times
to do this are whenever you refuel and prior to long trips.
Depending on the way the vehicle is driven and the operating condi­
tions, oil consumption can be up to 1/2 quart per 600 miles (0.5 liter
per 2,000 km). Consumption may be higher within the first 3,000
miles (5,000 km). •
