Working in the engine compartment
Be especially careful whenever you work in the engine
compartment.
Whenever you must perform any work in the engine compartment,
for example checking and filling different fluids, there is a risk of
injury, burns and accidents. To prevent personal injury always

Driv ing with an insufficient o il level is likely to cause severe damage
to the engine .
[ i J Tips
• The oil pressure wa rning display 9:!::r. is not an ind icator of the oil
level. Do not rely on it. Instead, check the oil level
in your engine at
r egula r inte rvals , prefe rably ea ch time you refuel , and always
before going on a long trip.
• If you have the impression your engine consumes excessive
amounts of o il, we recommend th at yo u consult an autho riz ed Aud i
dealer to have the cause of your concern properly diagnosed . Keep in
m ind that the accurate measu rement of oil consumption re quires
great care and may take some t ime. An authorized Audi dealer has
instructions about how to meas ure oil consumption accu rately .•
