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

If you choose to change your oil yourself , please note the following
im portant info rmat io n:
& WARNING
To reduce the risk of personal injury if you must change the engine
oil in your vehicle yourself:
• Wear eye protection .
• To reduce the risk of burns from hot engine oil, let the engine
cool down to the touch .
• When removing the oil drain plug with your fingers , stay as far
away as possible. Always keep your forearm parallel to the ground
to help prevent hot oil from running down your arm.
• Drain the oil into a container designed for this purpose, one
large enough to hold at least the total amount of oil in your
engine .
• Engine oil is poisonous . Keep it well out of the reach of chil­
dren.
• Continuous contact with used engine oil is harmful to your
skin. Always protect your skin by washing oil off thoroughly with
soap and water .

W For the sake of the environment
• Before changi ng yo ur oil, fir st ma ke s ure you know w here you c an

• Always dispose of used eng ine o il prope rly . Do no t dump it on
garden soi l, wooded areas, into ope n streams o r down sewa ge dr ains.
• Recycle used engin e oil by taking it to a used eng ine oi l collect ion
facility in your area, or contact a serv ice station .•

page 280 .
- Read the bra ke flu id level from the bra ke fluid reservoir
~ page 29 0, fig . 224. The bra ke fluid level must be
between the "MI N" and " MAX" m ark ings.
T he bra ke fluid reservoir is located at the rear partition of the engine
compartmen t on the left side=> page 281 .
The flu id level may drop slightly after some time due to the auto­
m atic adjus tment o f th e br ake pad s. This is no t ca use for alarm.
If the b ra ke fl uid leve l falls considerably below the "MIN" mark, t he
brake warn ing/i nd icator light ( U.S. models:

& WARNING (continued)
• 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.
& WARNING
California Proposition 65 Warning:
• Battery posts, terminals and related accessories contain lead
and lead compounds, chemicals known to the State of California
to cause cancer and reproductive problems. Wash hands after
handling.
0 Note
• Do not disconnect the vehicle battery when the ignition is
switched on or when the engine is running, otherwise, you will
damage electronic components in the electrical system.
• If your vehicle is going to stand for a long period of time without
being driven, protect the battery from "freezing", otherwise it will be
damaged and will then have to be replaced. •

- Remove the cover over the positive terminal in the plenum
chamber.
- Open the red cover on the positive pole::::;, fig. 225.
- Connect the charger connectors according to the instruc-
tions to the jump start bolts . (Bolts under the red cover=
"pos itive", Bolts with hex head = "negative").

A discharged battery can freeze at tempe ra tu res of only 3 2 °F ( 0 °C) .
Allow a froze n battery to thaw comp lete ly before attempt ing to
charge it~ & . H owever, we recommend not using a thawed batte ry
again because the battery casing can be c rack ed d ue to ice format ion
and can lea k battery acid.
Battery charging (Maximum charging rate of 30
amps/14.8 Volt)
Wh en charging a t /ow voltages (e.g. with a trickle charger), t h e
battery cables do not have to be disconnected first. The battery caps
should not be opened w hen c ha rging a ba ttery.
It is not necessary to remove the battery from the luggage compart ­
me nt.
Fast charging the battery (charging rate above 14.8
Volts)
For technical reasons do not use a battery cha rger that uses voltage
grea ter than 14.8 Vol ts to cha rge yo ur vehicle's batte ry.
& WARNING
Charging a battery can be dangerous .
• Always follow the operating instructions provided by the
battery charger manufacturer when charging your battery .
• Never charge a frozen battery . It may explode because of gas
trapped in the ice. Allow a frozen battery to thaw out first.
& WARNING (c on tinued )
• Do not reuse batteries which were frozen. The battery housing
may have cracked and weakened when the battery froze.
• Charge the battery in a well ventilated area. Keep away from
open flame or electr ical spark . Do not smoke . Hydrogen gas gener­
ated by the battery is explosive .
• To reduce the danger of explosion, never connect or disconnect
charger cable s while the charger i s operating.
• Fast charging a battery is dangerous and should only be
attempted by a competent technician with the proper equipment .
• Battery acid that may spill during charging should be washed
off with a solution of warm water and baking soda to neutralize
the ac id.
0 Note
N ever use a fast charger as a booster to start the engine. This w ill seri·
ously d amage sens it ive e lec tronic components, suc h as con trol units,
