Warning light in the instrument cluster
display
If the . warning light in the instrument cluster
display flashes, this can mean one of two things:
either the coolant
temperature is too high, or the
coolant
level is too low~ page 29.
If the needle is well in the upper area of the
gauge, the coolant temperature is too high.
Stop
the vehicle, switch the engine off, and allow it
to cool. If the warning light comes on again after
driving a short distance, contact an authorized
Audi dealer or other qualified workshop .
..&, WARNING
- Always observe the warning in ~ page 220,
before opening the hood and checking the
engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dr ipping from the engine compartment. You
cou ld burn yourself. Let the engine cool off
first so that you cannot hear or see any
steam or engine coo lant.
CD Note
- Mounting additional lights or accessories in
front of the air inlets reduces the cooling ef­
fect of the radiator. At high outside temper­
atures or high engine load, the engine could
overheat.
- The front spoiler has been designed to prop­
erly distribute the cooling air when the vehi­
cle is moving. If the spoiler is damaged, this
could reduce the cooling effect and the en­
gine could then overheat. Ask your author­
iz ed 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 permis­
sible engine RPM after the break-in period . Be-
~ fore reaching this area, move the selector lever U"I
..... \!) .....
Instruments and indicator lights
to posit ion D/S or ease your foot off the accelera­
tor pedal.
CD Note
The tachometer needle@~ page 10, fig. 3
should only briefly be in the red zone: you
could damage your engine! The beginning of
the red zone varies depending on the engine.
@ For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.
