Warning light in th e instrument clus ter
di splay
If the . warning light in the instrument cluster
display flashes , this can mean one of two th ings:
either the coolant
t emperature is too high, or the
coolan t
level is too low 9 page 29.
If the needle is well in the upper area of the
gauge, the coo lant temperature is too high.
S top
the veh icle , switc h the engin e off, and allo w i t
to coo l.
If the warning light comes on again after
driving a short distance , contact an authorized
Aud i dealer or other q ualified workshop .
..&, WARNING
-Always observe the warni ng i n 9 page 221,
before opening the hood and chec king the
engine coolan t level.
- Never open the engine hood if you see o r
hear steam, or if you see engine coolant
dr ipping from the engine compartmen t. You
cou ld burn yourself . Let the engine cool off
first so that you cannot hear o r see any
steam or engine coo lant.
CD Note
- M ount ing additional lights or accesso ries in
front of the air inlets red uces the cooling ef ­
fect of the radiator . At high outside temper ­
atures or high engine load, the eng ine could
overheat .
- The front spoiler has been designed to prop­
erly distribute the cooling air when the veh i­
cle is moving . If the spoiler is damaged, this
could reduce the cooling effect and the en­
gine could then overheat. Ask your author ­
i zed Audi dealer for assistance .
Tachometer (engine rev counter )
The tachometer indicates the engine RPM (revo ­
lutions per minutes) .
If engine RPM drops below 1,500 , you should
downshift to the next lower gear. The red area at
~ the end of the scale indicates max imum perm is -co
~ sible eng ine RPM after the break- in period . Be-
