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 284.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS~
& in "Working in the engine
compartment" on page
280.

Have the battery checked when you take your vehicle in for service .
You are well advised to replace a battery that is older than 5 years.
With certain types of a irbag deployment, the battery is disconnected
from the vehicle electrica l system for safety reasons~
& in "Repair,
care and disposal of the airbags" on
page 213.
Disconnecting the battery terminals
Some vehicle funct ions (power window regulators, for example) are
lost if the battery terminals are disconnected. These functions have
to be relearned after the battery termina ls are connected aga in . To
prevent this, the battery should only be disconnected from the
vehicle electr ica l system when absolute ly necessary for repairs.
Vehicles not driven for long periods
If you do not drive your veh icle over a period of several days or weeks,
electrical components are gradually cut back or switched off. This
reduces energy consumption and maintains starting capability ove r a
longer period
~ page 247.
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the master key remote function or
powe r seat adjustment, may not be available. The convenience func ­
tions will be available again when you turn on the ignition and start
the engine.
Winter operation
During the winter months, battery capacity tends to decrease as
temperatures drop. This is because more power is also consumed
while starting, and the headlights, rear window defogger, etc., are
used more often .
Avoid unnecessary power consumption, particu larly in city traffic or
when travel ing only short distances. Let your authorized Audi dealer
check the capacity of the vehicle battery before winter sets in
~ page 293. A well charged battery will not only p revent start ing
problems when the weather is cold, but will also last longer.
Safety first
(I] Tips
If your vehicle is left standing for several weeks at extremely low
temperatures, the vehicle battery shou ld be removed and stored
where it will not freeze. This will prevent it from being damaged and
having to be replaced. •
Working on the battery
Be especially careful when working on or near the
battery.
The battery is located in the luggage compartment under the
floor. Before you check anything in the lu~gage compart­
ment,
read and heed all WARNINGS =:,& .
Always heed the safety warnings, when working on the vehicle
battery or the vehicle electrical system to prevent injury .
The following WARNINGS are very important when
working on the battery:
Always heed the following WARNING SYMBOLS and safety pre ­
cautions when working on the battery.

& WARNING (co ntinued )
• When working on the battery , be sure not to short-circuit the
terminals with tools or other metal objects. This would cause the battery to heat up very quickly, which could lead to damage or
explosion and personal injury.
• When a battery is charged , it produces hydrogen gas which is
explosive and could cause personal injury.
• Always keep the battery well out of the reach of children.
• Before work is done on the electrical system, disconnect the
negative ground cable.
• Before performing any work on the electrical system, switch
off the engine and ignition as well as any electrical equipment.
The negative cable on the battery must be disconnected. If you are
just going to replace a light bulb, then it is enough to switch off
the lights.
• Before disconnecting the battery, switch off the anti-theft
alarm system! Otherwise you will set
off the alarm.
• When disconnecting the battery, first disconnect the negative
cable and then the positive cable.
• Before reconnecting the battery, make sure all electrical
consumers are switched off. Reconnect the positive cable first and
then the negative cable. Never interchange the cables· this could start a fire!
• Never charge a frozen or a thawed-out battery. It could
explode! If a battery has frozen , then it must be replaced. A
discharged battery can freeze over at 32°F (0°C).
• Make sure the vent hose is always attached to the opening on
the side of the battery .
• Never use batteries which are damaged . There is the danger of
an explosion! Always replace a damaged battery. _,.
