Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta­
tion .
Before you check anyt hing in the eng ine compart ­
ment,
alwa ys read and heed all WARNING S¢.&.
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 .

Cooling system
Coolant
The eng ine cooling system is fi lled w ith a mixture
of purified water and coolant additive at the fac­

T he coo lant level is monitored through
the . in­
