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.

Some states in the USA require permits to purchase diesel fuel. Check
with your State Motor Vehicle Department.
Diesel fuel may not be available outs ide the USA and Canada. Be sure
to check before traveling to other countries .
Winter operation
At temperatures below 20° F (- 7° C), Diesel fue l No. 2 loses its fluidity
due to wax separation, which may clog the fuel filter or tank filter and
keep the engine from running.
T o help the filter from being clogged by wax, the fuel fi lter in your
vehicle is automatically preheated. Preheating the fuel filter makes
operat ion of your vehicle possib le with Diesel fuel No. 2 down to -
10° F (-24° C).
If you expect temperatures below 5° F (-15° C) ask your fuel dealer
whether their Diesel fuel No. 2 is suffic iently w interized for the
prevailing and expected temperatures.
If not winte rized or insuffic iently winterized diesel fuel has already
thickened to the extent that the engine will not start, warm the
vehicle up by leaving it in a heated garage.
It is normal that the engine noise level (dieseling) is louder during the
warm-up period in winter.
It is also normal when whitish -blue smoke
comes out of the tailpipe after start ing and during warm-up. The
amount of smoke depends on the outside temperature.
Do not let your diese l engine id le unnecessari ly after a cold start.
Driving off slowly will shorten the warm-up period.
& WARNING
• Never use "starting assist fluids." They may be potentially
explosive or cause a "run-away" engine condition. This could
result in serious engine damage and personal injury.
• Never use fuel line anti-freeze offered for gasoline engines.
Safety first
0 Note
• Your diesel engine has been specifically designed to operate only
on Ultra Low Sulfur Diesel fue l. Therefore, never use home heating oil
or regu lar gaso line. The properties of these fuels may cause serious
damage to the fuel injection system and to the engine. Using these
fue ls can cause expens ive eng ine repairs and will also adversely affect
your New Vehicle Limited Warranty.
• If diesel fuel should get on any rubber hose, it must be wiped off
immediately. Then wash the contaminated hose portion with soap
and warm water. Do not allow diesel fuel to rema in on connecting
hoses. They may deve lop leaks and cause serious damage. •
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear side panel behind the
fue l filler flap.
If the power locking system should fa il, you can still open the flap
manually - for detai led instructions see=>
page 224.
You ca n find the fuel tank capacity of your vehicle in Technical Data
=> page 296 .
The label on the inside of the fue l filler flap tells you the correct fuel
for your veh icle. For more information about fuel specifications, see
=> page 219.
Your vehicle fuel tank has an on-board refuelling vapor recovery
system . This feature helps to prevent fuel vapors from escaping from
the tank and polluting the environment while you refuel your vehicle.
In order to fill the tank properly while protect ing the environment,
please follow this refueling procedure carefully. .,,

Engine oil
Engine oil specifications
The engine oil used in your Audi needs the right kind of oil.
The engine in your Audi is a sophisticated powe rp lant t hat was buil t
to exacting spec ifications . Th is engine needs the r ight kind of engine
oil that meets specifications regarding quality and viscosity so that it
can run smoo thly a nd reliably . Choosing the right o il and chang ing oi l
w ith in the time and mileage intervals printed in your vehicle 's
W arranty
& Mainte nance booklet ma tters a lot more today than i t did
years ago. Audi has developed a special quality standard for eng ine oil
t ha t wi ll help assure tha t your veh icle's engi ne will get t he lubri cat io n
it needs for proper operation .
Modern engine lu brication has take n a quantum leap in the last few
years . Many synt het ic oils available today provide be tte r engine lub ri­
cation that can outlast tradit ional petro leum-based oi ls, making
t hem a smart choi ce fo r use througho ut the life of your Aud i.
Whether you use synthetic or petroleum-based engine oil, the oil that
you use mus t conform to A udi's oil quality standard VW 5 02 00 (veh i­
cles wit h gasoline eng ine) and VW 507 00 (vehicle with diese l
eng ine) to help keep your ve hicle's engine runn ing smooth ly and help ..,

___ C_ h_ e_c _k _i _ n _g ~ a_n _d_ f_il _l_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 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. •
