If the engine does not start immediately, stop trying after 10 seconds
and then try to restart the engine about 30 seconds later. After a cold engine is started, there may be a brief period of
increased
noise because oil pressure must first build up in the hydraulic valve
adjusters. This is normal and not a cause for concern.

& WARNING
• You should perform braking maneuvers for the purpose of
cleaning the brake system only if road conditions permit. Other
road users must not be put at risk - you may cau se an accident!
• Before descending a steep grade, reduce speed and shift trans
mission into a lower gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or too often . This could
cause the brakes to get hot and diminish braking efficiency.
• Do not "ride the brakes " by resting your foot on the pedal when
you do not intend to brake . This may cause the brakes to overheat ,
premature wear and increased stopping distance.
• Under certain climatic and operating condition s such as
passing through water , driving in heavy rain or after washing the
& WARNING (co ntinued )
vehicle, the effectiveness of the brakes can be reduced . In winter,
ice can ac cumulate on the brake pads, linings, dis cs and drums.
Carefully apply brakes for a test. Brakes will dry and ice coatings
will be cleaned off after a few careful brake appli cations.
• Driving for an extended period of time on salt-covered roads
without u sing your brakes can also affect braking efficiency . Clean
off accumulated salt coating from b rake discs and pads with a few
careful brake applic ations.
• If you damage the front spoiler, or if you install a different
spoiler, be sure the air flow to the front brakes i s not obstructed .
Otherwise the brake system could overheat reducing the effective
ness of the entire brake system.
• Failure of one brake circuit will impair the braking capability
resulting in an increased stopping di stance. Avoid driving the
vehicle and have it towed to the nearest authorized Audi dealer or
qualified workshop.

damaged, the brake pedal mu st be pressed considerably harder to
make up for the lack of booster assistance. •

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

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.

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 power plant that was built
to exacting specifications. This engine needs the right kind of engine
oil that meets specifications regarding 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 vehicle's
Warranty
& Maintenance booklet matters a lot more today than it did
years ago. Audi has developed a special quality standard for engine oil
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 lubri
cation 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 oil quality standard VW 502 00 to help keep your vehicle's engine running smoothly and help prevent
the formation of harmful deposits, sometimes called "sludge", that
over time can lead to expensive repairs.
Safety first
At the time of printing, engine oils available in the U.S. and Canada
that meet the exacting specifications of Audi oil standard VW 502 00
are synthetic engine oils. This does not mean, however, that every
synthetic engine oil will meet Audi oil standard VW 502 00. So always
be sure that you use an approved oil.
To help prevent the formation of harmful deposits use only oil with
the following specifications printed on the oil container:
Audi oil standard VW 502 00
Oil container labels may carry the specification singly or in combina
tion with other designations and oil quality standards.
Viscosity
Engine oils are graded according to their viscosity. The proper
viscosity grade oil for your engine depends on climactic or seasonal conditions where you drive. You can use oil with a viscosity grade of
SAE SW40 across all temperature ranges for normal driving condi
tions.
However, if engine oil viscosity grade SAE SW40 is not available, you
can also use viscosity grade SAE SW-30 or SAE OW-40 as long as it
meets Audi oil quality standard VW 502 00 specifications.
Because engine oil that meets the Audi oil standard may not be avail
able everywhere when you need it, we strongly recommend that you
always carry with you an extra quart (liter) of oil that expressly
conforms to the VW 502 00 specification, in case you have to top off
the oil while on the road.
Only if the level of the oil is at or below the minimum mark - and no
oil that expressly conforms to Audi oil standard VW 502 00 specifica
tions is available -may you top off with a high quality engine oil, pref
erably synthetic-based, that meets ACEA A3, ACEA AS or ACEA BS or
API SL specifications, but even then, only in viscosity grades SAE SW-
40, SAE SW-30, or SAE OW-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 conform to Audi oil specification
vw 502 00. ..
Vehicle care Technical data

-Checking and filling
-------=----- -=-----------------------------------------
For more information about engine oil that has been approved for
your veh icle, please contact either your authorized Audi dealer or
Audi Customer Relations at 1 (800) 822-2834 or visit our web site at
www.audiusa .com or www.audicanada.ca . Here you will also find a
current list of oils (manufacturers, brand names etc.) that conform to
Audi oil standard VW 502 00 .
Changing the engine oil
The engine oil and oil filter must be changed according to the mileage
(kilometers) and time intervals specified in your vehicle's Warranty
&
Maintenance booklet . Do not exceed these intervals - harmful
deposits from o ld engine oil can reduce engine performance and can
lead to expensive engine repa irs.
Changing the oil at the recommended intervals is so very important
because the lubricating properties of oil decrease gradually during
normal vehicle use. If you are not sure when you have your oil
changed, ask your authorized Audi Service Adviso r.
Under some circumstances the engine o il should even be changed
more frequent ly. Change oil more often if you drive mostly short
distances, operate the veh icle in dusty areas or mostly under stop
and-go traffic conditions, or when you use your vehicle where temper
atures stay below freez ing po int 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 essentia l that you change yo ur oil at the recommended intervals
using only engine oil that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle Warranty does not cover
damage or malfunctions due to fa ilure to follow recommended main
tenance 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 internal
eng ine components, all inte rnal comb ustion eng ines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change sign ifican tly over the life of the engine. Typically,
engines with a specified break-in period (see~
page 246) consume
more oil dur ing the break- in period than they consume after oil
consumption has stab ilized.
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
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
cluster lights up, you should check the oil level as soon as possible
~ page 279. Top off the oil at your earliest convenience~ page 279.
