Changing the engine oil
We recommend that hove your oil changed by on
authorized Audi dealer or a qualified service sta­
tion .
Before you check anyt hing in the engine compart ­
ment,
alw ays re ad and h eed all W ARNINGS ¢ &
in Working in the engine comportment on
page 272.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
nance booklet . This is very important because the
lubricating properties of oil diminish gradually
during normal vehicle use.
Under some circumstances the engine oi l should
be changed more frequently. Change oil more of­
ten if you drive mostly short distances, operate
the vehicle in dusty areas or under predominantly
stop-and-go traffic condit ions, or have your vehi­
cle where temperatures remain below freezing
for extended periods .
Detergent additives in the oil will make fresh oil
look dark after the engine has been running for a
short t ime . Th is is normal and is not a reason to
change the oil more often than recommended .
Because of the problem of proper disposal, along
with the special tools and necessary expertise re­
qu ired, we strongly recommend that you have
your oil changed by an authorized
A ud i d ea ler or
a qualified se rvice station .
If you choo se to chang e your o il y ou rse lf, please
note the following important information:

Check ing and F illing
- To reduce the risk of burns from hot engine
oil, let the engine cool down to the touch.
- When removing the oil drain p lug 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

- 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 children .
- Continuous contact with used engine o il is
harmful to your skin. Always protect your

the ma intenance schedule may be a condition fo r
upho ld ing a possib le warranty claim made within
the warranty period.
Above all , ope rational safety can be adversely af­
fected, creating unnecessa ry risks fo r yo u and
your passengers.
I f in do ubt about any servicing, have it done by
your author ized Audi dealer or any other prope rly
eq uipped and qua lified workshop. We strongly
u rge yo u to g ive your author ized Audi dealer the
