Vehicle care I I irechnical data

If the indicator goes all the way to the right side inside the coolant
temperature gauge, then the engine coolant temperature is too
high.
Pull off the road to safe location, turn off the engine and let it
cool down.
If the warning light comes on again after you have driven
a short distance, contact a qualified workshop.
& WARNING
• Always observe the warning in :::::, page 299, "Engine compart­
ment", 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 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.
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 0:::::, page 12, fig. 2 is the left 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 is pointing at the "2" the engine is turning
at 2,000 RPM.
Controls and equip­ ment
Instruments and warning/indicator lights
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 maximum
permissible engine RPM after the break-in period . Before reaching
this area, move the selector lever to position "D (Drive)" 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.
<£> For the sake of the environment
Upshifting early saves fuel and reduces engine noise.•
