Driving and environment
- Never put too much motor oil in your engine=> page 285,
"Adding engine oil~".
- Never try to pus h- or tow-sta rt your vehicle.
The catalytic converter is an efficient "clean-up" dev ice built into the
exhaust system of the vehicle. The catalytic converter burns many of
the pollutants in the exhaust gas before they are released into the
atmosphere.
T he exclusive use of unleaded fuel is c riti cal ly import ant for the life of
the catalytic converter and proper funct io ni ng of the eng ine.
& WARNING
• Do not park or operate the vehicle in areas where the hot
exhaust sy stem may come in conta ct with dry gras s, brush, fuel
spill or other material which can cause a fire.
• Do not apply addit ional undercoat ing or rustproofing on or
near the exhaust manifold , exhau st pipes , catalytic converte r or
heat shield s. During driving, the sub stan ce u sed f or under coating
c ould o ve rheat and cause a fire.
0 Note
• Be aware that just one tank filling with leaded fuel w ill already
ser iously degr ade the performance of the ca talytic co nve rter.
• Do not exceed the correct engine oil level =>
page 285.
• Do not dr ive until the f uel tank becomes com plete ly empty . T he
engine could misfire . Unburned fuel cou ld also get into the ex ha ust
system and t his co ul d cause t he ca talyt ic converter to ove rheat .
• Do not turn off the ignition while the vehicle is moving.
• Do not continue to operate your vehicle u nder these conditions, as
otherwise f uel can reac h the c ata ly tic conve rter. This co uld res ult in
over heat ing of the converter, requir ing its replacement.
• T o ass ure eff icien t operat ion of the Emission Cont rol System: -
Have your vehicle maintained properly and in accordance with
th e se rvice reco mmend ations in your W arran ty

~ For the sake of the environment
Even when the Emission Contro l System is operat ing proper ly, the
exhaust gas can have a sulfur-like exhaust gas smell u nder some
operating states. This depends on t he sulfur content of the fue l being
used . Using a different brand of fuel may help , o r fil lin g the tank with

Observe speed limits. In some areas, speeds for vehicles towing
t railers are lowe r than for regular veh icles.
Always apply brakes early. When dr iv ing downh ill, sh ift in to a lower
gear to use the engine 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 8 must be observed care­
fully. If the needle moves close to the upper end of the scale, reduce
speed immediately and/or turn off the air conditione r.
If the coolant temperature warning light in the instrument cluster
star ts flashing
-t- , pull off the road, stop and let the engine idle for
about two minutes to prevent heat bu ild-up.
& WARNING
Anyone not properly restrained in a moving vehicle is at a much
greater risk in an accident. Never let anyone ride in your car who is
not properly wearing the restraints provided by Audi. u
Trailer towing tips
Important to know
------------
Your vehicle handles differently when tow ing a tra iler because of the
additiona l weight and different weight distribution. Safety, perfor ­
mance and economy will greatly depend on how carefu lly you load
your trailer and operate your rig .
Before you actua lly tow your trailer, practice turning, stopping and
backing up in an area away from traffic. Keep pract icing until you have
become completely familiar with the way your vehicle-t railer combi­
nation behaves and responds.
Controls and equip­
ment Safety first Vehicle operation
Backing up
is d iff icult and requ ires practice . Backing up with a trailer
generally requires steering action opposite to that when backing up
your vehicle without a trailer.
Maintain a greater distance between your vehicle and the one in front
of you. You will need more room to stop . To compensate fo r the
trailer, you will need a larger than norma l turning radius.
When passing, remember that you cannot accelerate as fast as you
normally would because of the added load. Make sure you have
enough room to pass. After passing, allow plenty of room for you r
trailer before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane changes .
[I) Tips
• Do not tow a trai ler during the break-in per iod of your vehicle.
• If you tow a tra iler, your Audi may requi re more frequent mainte­
nance due to the extra toad~
page 343. •
Parking on a slope
Do not park on a slope with a trailer. If it cannot be
avoided, do so only after doing the following:
When parking:
-Apply the foot brake.
- Have someone place chocks under both the vehicle and the
trailer wheels.
- With chocks in place, slowly release the brakes until the
wheel chocks absorb the load.
- Turn the wheels towards the curb.
- Apply the parking brake .
- Move the se lector lever to

Natural leather
Audi makes great efforts to maintain the properties,
natural look and feel of interior leather.
General
We offe r many different types of leathe r on our veh icles. Most are
different types of nappa leather, which has a smooth surface and
comes in various colors.
Th e intensity of the colo r determines the visual cha racteristics and
appearance. If the surface of the leather has a typica l natural look,
then the leather is a nap pa leather that has been left in a relatively
natural condition. This leather offers particularly good comfort and
breathes well. Fine veins, closed grains, insect bites, skin folds, and
subtle variations in color remain visible. These characteristics demon­
strate that the mater ial is natu ral.
Natural nappa leather is not covered by a color finish. It is therefore
more sensitive to soiling and wear, which is something you need to ..,_

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.
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 5W40 across all temperature ranges for normal driving condi­
tions.
However, if engine oil viscosity grade SAE 5W40 is not available, you
can also use viscosity grade SAE 5W -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 5W-
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.
For more information about engine oil that has been approved for
your vehicle, 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 old engine oil can reduce engine performance and can
lead to expensive engine repairs.
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 Advisor .
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 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 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 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 failure 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. •
Safety first
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 oil. Oil consumption varies from engine to engine
and may change significantly over the life of the engine. Typically,
engines with a specified break-in period (see~
page 250) 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 consumption
may increase over time until replacement of worn components may
become necessary.
With all these variables 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 284. Top off the oil at your earliest convenience~ page 285.

• Before winter sets in, have the coolant checked to see if th e
coolant additive in your vehicle is sufficient to meet the climate
conditions . This is especially important if you live in a region where
the winter is extremely cold .
If necessary, increase the proportion of
coola nt additive to 60% .
• When adding coolant additive to your cooling system, remember:
- We recommend using only coolant additive Gl2++ (check the
label) for your vehicle . This coolant additive is available at autho­
r iz ed Audi dealers. Other types of antifreeze can significantly
reduce corrosion protection . The resulting corrosion can cause
a
loss of coolant and serious engine damage.
• Do not add any type of radiator leak sealant to your vehicle's
eng ine coolant . Adding radiator repair fluid may adversely affect the
function and performance of your cooling system and could result in
damage not covered by yo ur New Vehicle Limited Warranty .•

The expansion tank in your vehicle is equipped with an electric coolant
level sensor.
When the coolant level is too low, the warn ing light in the Auto-Check
System ~
page 29 will blink until you add coolant and the level has
been restored to normal. Even though there is an electric coolant
level sensor, we still recommend you check the coolant level from
time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling system. In the event of
coo lant loss, the cooling system should be inspected immed iate ly by
your authorized Audi dealer .
It is not enough merely to add coolant.
In a
sealed system, losses can occur only if the boiling point of the
coolant is exceeded as a result of overheating.
& WARNING
The cooling system is under pressure and can get very hot. Reduce
the risk of scalding from hot coolant by following these steps.
• Turn off the engine and allow it to cool down.
• Protect your face, hands and arms from escaping fluid and
steam by covering the cap with a large, thick rag.
• Turn the cap slowly and very carefully in a counter-clockwise
direction while applying light, downward pressure on the top of
the cap.
• To avoid being burned, do not spill antifreeze or coolant on the
exhaust system or hot engine parts. Under certain conditions, the
ethylene glycol in engine coolant can catch fire.
0 Note
Do not add any type of radiator leak sealant to your vehicle's engine
coo lant. Adding radiator repair fluid may adverse ly affect the func­
tion and performance of your cooling system and could result in
damage not covered by your New Vehicle Limited Warranty.•

- Twist the cap on again
tightly.
Replacement engine coolant must conform to exact specifications
~ page 286, "Coolant". Even in an emergency, if coolant additive
G12 ++, G12+ or G12 is not available, do not use a different additive.
Use plain water instead until you can get the correct additive and can
restore the correct ratio. This should be done as soon as possible .
If you have lost a considerable amount of coolant, then you should
add cold antifreeze and cold water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the ''MAX" mark. Excess coolant will be
forced out through the press ure re lief va lve in the cap when the
eng ine becomes hot .

The tires and rims are essential parts of the vehicle's design . The tires
and rims approved by Audi are specially matched to the characteris­
tics of the vehicle and can make a major contribution to good road holding and safe handling when in good condition and properly
inflated
~ & .
We recommend that all work on tires and wheels be performed by an
authorized Audi dealer . They are familiar with recommended proce­
dures and have the necessary special tools and spare parts as well as
the proper facilities for disposing of the old tires.
Authorized Audi dealers have the necessary information about tech­
nical requirements for installing or changing tires and rims.
Replacing tires and wheels
Tires should be replaced at least in pairs and not individually (for
example both front tires or both rear tires together) .
Be sure to read and heed the information to the tire pressure moni­
toring system*.
Always buy replacement radial tires that have the same specifications
as the tires approved for your vehicle by Audi. Replacement tires must
always have the same load rating specification as the original equip ­
ment or approved optional tires listed in the table~
page 300.
Audi-approved specification tires are specially matched to your
vehicle and its load limits, and can contribute to the important road- holding, driving characteristics, and safety of the vehicle
. The table
(~ page 300) lists specifications of the tires approved for the Audi
models covered by your Owner's Literature.
The tire pressure label located on driver's side B-pillar (~
page 300,
fig. 228) lists the specifications of the original equipment tires
installed on your vehicle at the time it was manufactured.
Federal law requires tire manufacturers to place standardized infor­
mation on the sidewall of all tires~
page 307, fig. 231. This infor­
mation identifies and describes the fundamental characteristics, the
quality grade of the tire and also provides a tire identification number
for safety standard certification and in case of a recall.
Tire specifications
Knowledge of tire specifications makes it easier to choose the correct
tires . Radial tires have the tire specifications marked on the sidewall,
for example:
P255 / 35 R19 96Y XL
This contains the following information:
P Indicates the tire is for passenger cars (where applicable)
255 Nominal tire width in mm of the tire from sidewall edge to side-
wall edge. In general, the larger the number, the wider the tire
35 Height/width ratio in percent (aspect ratio)
R Tire construction : Radial
19 Rim diameter code (in inches)
96 Load rating code
Y Speed rating letter code
XL (or "xl", "EXTRA LOAD", or "RF" Indicates that the tire is a"Rein­
forced" or an "Extra Load" tire
M+S (or "M/S") Indicates that the tire has some mud and snow capa­
bility
The tires could also have the information of direction of rotation
