A WARNING
- Always observe the warning in

and checking the engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment.
You could burn yourself. Let the engine
cool off first so that you cannot hear or
see any steam or engine coolant .
(D Note
-Mounting additional lights or accessories
in front of the air inlets reduces the cool­
ing effect of the rad iator. At high outside
temperatures or high eng ine load , the
engine could overheat.
- The front spoiler has been designed to
properly distribute the cooling air when
the veh icle is moving .
If the spoiler is
damaged , this cou ld reduce the cooling
effect and the engine co uld then over­
heat. Ask your authorized Aud i dealer for
assistance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
I f engine RPM drops below 1,500, you should
downshift to the next lower gear . T he red area

perm issible engine RPM after the break-in pe­
riod. Before reaching this area, move these­
lector lever to position 0/5 or ease your foot
off the accelerator pedal.
