The most important check points .
-For safety reasons, the hood must always be
latched securely while dr iving. Because of
this, always check the hood after closing it
to make sure it is latched correctly . The
hood is latched if the front corners cannot

Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta­
tion .

in Working in the engine comportment on
page 314.
The engine oil must be changed accord ing to the
intervals specified in your Warranty
& Mainte­
nance booklet . This is very important because the
lubricat ing propert ies 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 most ly short distances, operate
the vehicle in dusty areas or under predominant ly
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 time. 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 c hanged by an authorized
A udi de aler or
a qualified service station .
