The exclusive use of unleaded fuel is critically im­
portant for the life of the catalytic converter and
proper functioning of the engine.
A 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 mani­
fold, exhaust pipes, catalytic converter or
heat shields. During driving, the substance
used for undercoating could overheat and
cause a fire.
([) Note
-Be aware that just one tank filling with lead­
ed
fuel will already seriously degrade the
performance of the catalytic converter.
- Do not exceed the correct engine oil level
~page 160.
- Do not drive until the fuel tank becomes
completely empty. The engine could misfire.
Unburned fuel could also get into the ex­
haust system and this could cause the cata­
lytic converter to overheat.
- Do not turn off the ignition while the vehicle
is moving.
- Do not continue to operate your vehicle un­
der these conditions, as otherwise fuel can
reach the catalytic converter. This could re­
sult in overheating of the converter, requir­
ing its replacement.
- To assure efficient operation of the Emission
Control System:
- Have your vehicle maintained properly and in accordance with the service recommen­
dations in your Warranty
& Maintenance
booklet.
- Lack of proper maintenance as well as im­
proper use of the vehicle will impair the
function of the emission control system
and could lead to damage.
Driving and environment
{® For the sake of the environment
Even when the Emission Control System is op­
erating properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. This depends on the sulfur
content of the fuel being used. Using a differ­
ent brand of fuel may help, or filling the tank
with lead-free super grade gasoline .
Shutting down vehicle
If you would like your vehicle to remain inopera­
tive for a longer period of time , contact an Audi
or other specialized dealer. They can advise you
on necessary precautions e.g. corrosion preven­
tion, maintenance and storage. Pay attention to
additional information concerning the battery.
Refer to~
page 164.
Operation and
maintenance
Fuel economy, environmental impact, and wear
on your engine, brakes and tires largely depend
on three factors:
-your personal driving style
- operating conditions
- technical limitations
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 only affects its safety and ability
to hold its value, it also affects
fuel consump­
tion.
The amount of oil used is related to engine load
and speed.
It is normal for the oil consumption of a new en­
gine to reach its lowest value after a certain mile­
age has been driven.
You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly as­
sess oil consumption .
This also applies to fuel consumption and engine output . .,,.

Engine oil
Engine oil specificat ions
The engine oil used must conform to exact speci­
fications .
The service interval display in the instrument
cluster of your vehicle will inform you when it is
time for an oil change . We recommend that you
have your oil changed by an authorized Audi Serv­
ice Advisor.
If you have to top off the oil between oil changes,
use the Audi oil quality standard specified in the
table.
Audi oil quality standard
Gasoline
VW 502 00 or
engine vw 504 00
Using the proper engine oil is important for the
functionality and service life of the engine. Your
engine was factory-filled with a high-quality oil
which can usually be used throughout the entire
year.
(D Note
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
Manual and Warranty
& Maintenance booklet.
- Use only a high quality engine oil that ex-
pressly complies with the Audi oil quality
standard specified for your vehicle's engine .
Using any other oil can cause serious engine
damage.
- Do not mix any lubricants or other additives
into the engine oil. Doing so can cause en­
gine damage.
158
(D Tips
If you need to add oil and there is none availa­
ble that meets the Audi oil quality standard
your engine requires, you may add a total of
no more than 0.5 quart/liter of a high-quality
"synthetic"oil that meets the following speci­
fications.
- ACEA A3 or API SM with a viscosity grade of
SAE OW-30, SAE 5W-30 or SAE 5W-40.
- 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.
Engine oil consumption
The engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool all of
its moving ports.
In order to provide effective lubrication and cool­
ing of internal engine components, all internal
combustion engines consume a certain amount
of oil. Oil consumption varies from engine to en­
gine and may change significantly over the life of
the engine. Typically, engines with a specified break-in period (see
¢ page 142) consume more
oil during the break-in period than they consume
after oil consumption has stabili zed.
Under normal conditions , the rate of oil con­
sumption depends on the quality and viscosity of
the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient tem­ perature and road conditions . Further factors are
the amount of oil dilution from water condensa­
tion 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 estab­
lished or specified. There is no alternative to reg­
ular and frequent checking of the oil level, see
Note.

Tires and wheels
-The use of incorrect tire pres­sure values can lead to acci­
dents or other damage. There­
fore it is essential that the driver observe the specified
tire pressure values for the
tires and the correct pressures
for the function of the tire pressure monitoring system.
-Always inflate tires to the rec­ ommended and correct tire
pressure before driving off.
-Driving with underinflated tires bend more, letting them get too hot resulting in tread
separation, sudden tire failure
and loss of control.
-Excessive speed and/overload­
ing can cause heat build-up,
sudden tire failure and loss of
control.
-If the tire pressure is too low
or too high, the tires will wear
prematurely and the vehicle
will not handle well.
-If the tire is not flat and you do not have to change a wheel
immediately, drive at reduced
speed to the nearest service
station to check the tire pres­
sure and add air as required .

d) Note
Driving without valve stem caps
can cause damage to the tire
valves. To prevent this, always
make sure that factory instal­
led valve stem caps on all
wheels are securely mounted on the valve.
@ For the sake of the environment
Underinflated tires will also in­
crease the fuel consumption.
Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop. Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­
sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are ...

Tires and wheels
Ask your authorized Audi dealer or qualified
workshop for permitted
winter tire sizes. Use on­
ly radial winter tires.
Winter tires lose their effectiveness when the
tread is worn down to a depth of 0.157 inch
(4 mm).
Only drive with winter tires under winter condi­
tions. Summer tires handle better when there is
no snow or ice on the roads and the temperature
is above 45 °F (7 °().
Please always remember that winter ti res may
have a lower speed rating than the tires originally
installed on your vehicle at the time it was manu­
factured . Please see¢ page 189, Speed roting
(letter code) for a listing of the speed rat ing let­
ter codes and the maximum speed at which the
t ires can be driven.
The speed rating letter code(¢ page 174) is on
the side wall of the tire ¢page 186.
A WARNING
Winter tires have maximum speed limits that
may be lower than your vehicle's maximum
speed. Always know the maximum speed be­
fore driving off . Never drive faster than the
speed permitted for your specific winter tires .
This will cause damage to the tires leading to
an accident and serious personal injury to you
and your passengers.
A WARNING
Driving faster than the maximum speed for
which the winter tires on your vehicle were designed can cause tire failure including a
blowout and sudden deflation, loss of contro l,
crashes and serious personal injuries. Have
worn or damaged tires replaced immediately.
- Winter tires have maximum speed rating that may be lower than your vehicle's maxi­
mum speed .
- Never drive faster than the speed for which
the winter or other tires installed on your
vehicle are rated.

A WARNING ,_ -
Always adjust your driving to the road and
traffic conditions . Never let the good accelera ­
tion of the winter tires and all-wheel drive
tempt you into taking extra risks. Always re­
member:
- When braking, an all-wheel drive vehicle
handles in the same way as a front drive ve­
hicle.
- Drive carefully and reduce your speed on icy
and slippery roads, even winter tires cannot
help under black ice conditions.
@ For the sake of the environment
Use summer tires when weather conditions
permit . They are quieter, do not wear as
quickly and reduce fuel consumption.
, Snow chains
Snow cha ins may be fitted only to the rear
wheels , and only to certain tire sizes. Ask your au­
thorized Audi dealer on which tire sizes snow
chains can be used.
The snow chains must have low-profile links and
must not be thicker than 0.53 inch (13 .5 mm) ,
including the lock.
Remove wheel center covers before putting snow
chains on your vehicle ¢Ci) . For safety reasons
cover caps must then be fitted over the wheel
bolts . These are available from authorized Audi
dealers .
A WARNING
Using the wrong snow chains for your vehicle
or installing them incorrectly can increase the
risk of loss of control leading to serious per­
sonal injury .
- Snow chains are available in different sizes.
Always make sure to follow the instructions
provided by the snow chain manufacturer .
- When driving with snow chains, never drive
faster than the speed permitted for your
specific snow chains .
- Always observe local regulations.
