Instrument s and warning /indicator lights 11
A WARNING
- Always observe the warning in
c::> page 206 , 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 .
(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).
If engine RPM drops below 1,500, you should
downshift to the next lower gear . T he red area
at the end of the scale indicates maximum
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.
@) Note
The tachometer needle@c::> page 10,
fig . 3 shou ld only briefly be in the red
zone: you could damage your engine! The
beg inning of the red zone varies depend-
ing on the engine .
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.

Auto Check Control
Some functions and vehicle components are
scanned for their operating status when you
switch the ignition on and whi le you are driv­
ing . Malfunctions or required service proce­
dures are signaled audibly and indicated by
red and yellow illuminated symbols and re­
minders in the d isplay.
A WARNING
--- Never rely exclusively on the outside
temperature display to determine if a
road surface is icy or not . Keep in mind
that road surfaces , espec ially br idges
and overpasses, could be ice covered and
slippery even at an outside temperature
above 41 °F (+S °C).
- Always remember,
even if the "snow­
flake" symbol (ice warning) does not ap­
pear in the disp lay, black ice cou ld be on
the road.
- Always reduce your speed and drive with
specia l care in cold weather conditions
when the chance of encountering icy
road surfaces increases.
¢j) Tips
If the vehicle is stationary, or if you are
driving at a very low speed, the tempera­
ture shown in the display might be slightly
higher than the actual outside tempera­
ture. This i.s caused by the heat being radi­
ated from the engine .
