The instrument cluster illuminates whenever you switch on the igni­
tion with the
vehicle headlights off. The instrument cluster illumina ­
tion dims automatically as the daylight begins to fade away. It goes
out completely when the outside light is very dim. The reason for
this is to remind you to turn on the headlights when the light condi­
tions become poor. •
Engine coolant temperature gauge
The engine coolant gauge~ page 12, fig. 2 G) only works when the
ignition is on . To prevent damage to your engine, please note the
following important points:
Engine cold
As long as the needle remains at the left end of the gauge, the
engine still has not reached its operating temperature . Avoid high
engine speeds, heavy engine loads and heavy throttle.
Normal temperature
When the engine has reached its operating temperature, the needle
will move into the middle of the gauge and remain there. If the
engine is working hard at high outside temperatures, the needle
may turn further to the right . This is no cause for concern as long as
the
- F-warning light in the instrument cluster does not illuminate.
When the
-L warning light starts to flash, this can mean one of two
things: either the coolant
temperature is too high, or the coolant
level is too low~ page 31.
_& WARNING
• Always observe the warning in ~ page 242, "Engine compart­
ment" before opening the engine hood 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
Controls and equip ­
ment

& WARNING (continued)
could burn yourself. Let the engine cool off first so that you cannot
hear or see any steam or engine coolant.
0 Note
• Mounting additional lights or accessories in front of the air inlets
reduces the cooling effect of the radiator. At high outside tempera­
tures or high engine load, the engine could overheat.
• The front spoiler has been designed to properly distribute the
cooling air when the vehicle is moving. If the spoiler is damaged,
this could reduce the cooling effect and the engine could then over­
heat. Ask your authorized Audi dealer for assistance. •
Tachometer (engine rev counter)
The tachometer indicates the engine RPM (revolutions per
minutes).
The tachometer ®~ page 12, fig. 2 is the left one of the two large
clock -type displays.
The engine turns at a speed
1,000 times the single digit in the
display, e.g. if the needle points at the "2", the engine turns at
2,000 RPM.
If the engine RPMs drop below 1,500, you should downshift to the
next lower gear. The red area at the end of the scale indicates
maximum permissible engine RPMs after the break-in period.
Before reaching this area, you should either shift into the next
higher gear or ease your foot off the accelerator pedal.
0 Note
The tachometer needle should not move into the red range. If it
does, then only for a very short period of time. You could damage
your engine by driving at high RPM! _.
