current list of oils (manufacturers, brand names etc.) that conform
t o Audi oi l standard VW 502 00 .
Changin g the engine oil
The engine oil and oil filter must be changed according to the
mi leage (ki lometers) and time intervals specified in your vehicle's
Maintenance
& Warranty booklet. Do not exceed these interva ls -
harmful deposits from old engine oil can reduce engine perfor­
mance and can lead to expensive engine repairs.
Changing the oi l at the recommended intervals is so very important
because the lubricating prope rties of oi l decrease gradual ly during
normal vehicle use . If you are not sure when you have your oil
changed, ask your author ized Audi Serv ice Advisor.
Under some circumstances the engine oil should even be changed
more frequently. Change oil more often if you dr ive mostly short
distances, operate the vehicle in dusty areas or mostly under stop ­
and -go t raffic conditions, or when you use your vehicle where
temperatures stay be low freezing point for long per iods.
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.
Damag e or malfunctions due to lack o f mainten anc e
It is essentia l that you change your oi l at the recommended interva ls
using on ly engine oil that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle Warranty does not cover damage or ma lfunctions due to failure to follow recommended
main tenance and use requirements as set forth in the Aud i Owner's
Manual and Maintenance
& Warranty booklet. Your dealer wi ll have
t o deny warranty cove rage unless you present to the dealer p ro o f in
the form of Service or Repair Orders that all schedu led maintenance
was pe rformed in a timely manner. •
Engine oil consumption
The engine in your vehicle depends on an adeq uate
amount of oil t o lubric ate and c ool all of its m oving parts.
In order to provide effective lubrication and coo ling of interna l
engine components, al l interna l combustio n eng ines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change significant ly over the life of the engine . Typ ically,
engines with a specified break-in period (see=> page 267) consume
more oil du ring the break-in period than they consume after oil
consumption has stabi lized .
Unde r normal conditions, the rate of oil consumption depends on
the quality and v iscosity of the oil, the RPM (revolutions per minute)
at which the engine is operated, the ambient temperature and road
cond itions. Fur ther factors are the amount of oil di lu tion from wate r
condensation or fue l residue and the oxidation leve l of the oi l. As
any engine is subject to wear as mileage bu ilds up, t he oil consump ­
tion may increase over time until replacement of worn components
may become necessa ry .
With all these variables coming into play, no standard rate o f oi l
consumption can be established or specified . There is no alternative
t o regula r and frequent checking of the oil level, see
Note .
If the yel low engine oil level warning symbo l in the instrument
clus ter lights up, yo u should check the oil level as soon as
possible with the oil dipstick=> page 301. Top off the oil at your
ea rliest convenience => page 302 .
& WARNING
Before you check anything in the engine compartment , always
read and heed all WARNING S
=> & in "Working in the engine
compartment " on
page 297.

- You must add oil. Afterwards, 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 tr ips. •

cap locat ion
Before you check anything in the engine compartment,
always read and heed all WARNINGS~ & in "Working in
the engine compartment" on
page 297.
Unscrew the cap ~ fig. 234.
Carefully top off with the appropriate o il in 0.5 liter doses.
- Check the oil level again after two minutes ~
page 301.
Top off the oil again, if necessary.
Screw the cap back on the filling hole and slide the o il
dipstick in as far as it will go.
& WARNING
• While topping off, the oil must not come in contact with hot
engine parts -fire hazard!
• The oil filler cap must be properly secured to prevent oil from
being sprayed on the hot engine and exhaust system when the
engine is running -fire hazard!
• If your skin has come in contact with the engine oil , you must
subsequently cleanse it thoroughly.
0 Note
• T he oil level must not be above range @- danger of converter or
engine damage! Contact an au thorized dealership to draw off oil, if
necessary .
• Audi does not recommend the use of oil additives. They may
damage the engine and adversely affect your New Vehicle Warranty.
• Under no circumstances can the oil come in contact with the
sewage network or the soil.
• Observe and follow legal regulations when disposing of empty
oi l containers .•
Changing the engine oil
We recommend that have your oil changed by an autho­
rized Audi dealer or a qualified service station .
Before you check anything in the engine compartment, always read
and heed all WARNINGS ~
& in "Working in the engine compart ­
ment" on
page 297.
The engine oil must be changed according to the intervals specified
in your Maintenance
& Warranty booklet. This is very important ...

Tire pressure
Incorrect tire pressure causes premature wear and can cause
sudden tire blow-out. For this reason, tire pressure must be checked
at least once a month~
page 319.
Driving style
Driving fast around curves, heavy acceleration and hard braking
increase tire wear.
Rotating tires for more even wear
For all four tires on your vehicle to have the same service life, we
recommend that the front and rear tires are rotated according to the
tire manufacturer's suggested tire rotation intervals. Please remember the following:
• Tire rotation intervals may differ from the vehicle service inter­
vals outlined in your Maintenance and Warranty Booklet.
• The longer one tire is used in one location on the vehicle, the
more it wears at certain points; therefore, we recommend that you
follow the tire manufacturer's suggested tire rotation intervals.
• Vehicles with front-wheel drive experience more tread wear on
the front wheels compared to all-wheel drive (quattro®l .
• Please rotate tires as shown ~
page 323, fig. 243.
• Extra care must be taken when rotating direction -specific tires
~ page 344.
Wheel balancing
The wheels on new vehicles are balanced. However, various situa­
tions during everyday driving can cause them to become unbal ­
anced, resulting in vibrations you can usually feel through the
steering wheel.
Unbalanced wheels must be rebalanced to avoid excessive wear on
steering, suspension and tires. A wheel must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect wheel alignment can cause excessive tire wear, impairing
the safety of the vehicle. If tires show excessive wear, have the
wheel alignment checked by an authorized Audi dealer or qualified
workshop.
All Wheel Drive
Vehicles with quattro® must always have tires of the same size, construction and tread type. For details see~
page 264.
& WARNING
Sudden tire failure can lead to loss of control, a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators.
• Worn tires are a safety hazard, they do not grip well on wet
roads and increase your risk of "hydroplaning" and loss of control.
• Always keep chemicals that can cause tire damage, such as
grease, oil, gasoline and brake fluid away from tires.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds.
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. •

standards. Therefore, vehicles built for the U.S .A. and Canada differ
from vehicles sold in other countries.
If you plan to take your vehicle outside the continental limits of the
United States or Canada, there is the possibility that
• unleaded fuels for vehicles with catalytic converter may not be
available;
• fuel may have a considerably lower octane rating. Improper fuel
may cause engine damage;
• service may be inadequate due to lack of proper service facilities,
tools or testing equipment;
• replacement parts may not be readily available .
• Navigation systems for vehicles built for the U.S.A. and Canada
will not necessarily work in Europe , and may not work in other coun­
tries outside of North America.

Maintenance
General
Your vehicle has been designed to help keep maintenance require­
ments to a minimum. However, a certain amount of regular mainte­
nance is still necessary to assure your vehicle 's safety, economy and
reliability. For detailed vehicle maintenance consult your Mainte­
nance & Warranty booklet .
Under difficult operating conditions, for example at extremely low
outside temperatures, in very dusty regions, when towing a trailer
very frequently, etc., some service work should be performed
between the intervals specified. This applies particularly to:
• oil changes , and
• cleaning or replacing the air filter.
~ For the sake of the environment
By regularly maintaining your vehicle, you help make sure that emis ­
sion standards are maintained, thus minimizing adverse effects on
the environment. •
Important considerations for you and your
vehicle
The increasing use of electronics, sophisticated fuel injection and
emission control systems, and the generally increasing technical
complexity of today's automobiles, have steadily reduced the scope
of maintenance and repairs which can be carried out by vehicle
owners. Also, safety and environmental concerns place very strict
limits on the nature of repairs and adjustments to engine and trans­
mission parts which an owner can perform.
Maintenance, adjustments and repairs usually require special tools,
testing devices and other equipment available to specially trained .,_
