-When switching the ignition on, the nee­
dles in the instrument cluster move up­
ward briefly.
- The illumination for the instrument clus­
ter lights up whenever you switch on the
i gnition with the
vehicle headlights off.
As the daylight fades, the instrument
cluster illumination likewise dims auto­
matically and will go out completely
when the outside light is very low. This
feature is meant to remind you to switch
on the headlights w hen outside light
conditions become poor .
Tachometer (engine rev counter)
The tachometer CD q page 10, fig. 3 is the left
of the two large clock-type dis plays.
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.
The tachometer indicates the engine RPM
(revolutions per minutes). The red area at the
end of the scale indicates maximum permissi­
ble engine RPM after the break-in period. Be­
fore reaching this area, move the selector lev­
er to position "D (Drive)" or ease your foot off
the accelerator pedal.
(D Note
The tachometer needle should not move into the red range . If it does, then only for
a ve ry short per iod of time. You could
damage your engine by driving at high
RPM.
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.

Instrument s and warning /indicator lights 11

tion - can turn on the display field lighting for
a few seconds .
Engine coolant temperature gauge
The engine coo lant gauge ~ page 10, fig . 3 @
only wor ks when the ign ition is on. To prevent
damage to your engi ne, please note t he fo l­
lo wing important points :
Engine cold
As long as the need le rem ains a t the left end
of the gauge, the engine s till has not reac hed
its operating temperat ure. Avoid high engine
speeds, heavy e ngine loads and heavy throt­
tle.
Normal temperature
When the engine has re ache d its ope rat ing
temperature, the need le w ill move into the
mid dle of t he gauge and rema in there .
If the
engine is working hard at high outside tem ­
peratures, the needle may turn fu rther to the
right. This is no cause for concern as long as
the . war ning light i n the inst rument cluster
does not illuminate .
When the. warning light starts to f lash,
th is can mean one of two things: either the
coolant
temperature is too high, o r the coo l­
ant
level is too low ~ page 31 .
A WARNING
--Always obs erv e the warn ing in
~ page 17 2, Engine compar tment be ­
fore opening the eng ine hoo d and check­
ing the eng ine coolan t leve l.
- N ever ope n the eng ine hood if you see or
hea r ste am, or if you see e ngine c oo la nt
dripping from t he en gine compar tment .
You could burn yourse lf . Let the engi ne
coo l off fi rst so that you can not hear or
see any steam or engine coo lant.
(D Note
- M ounting ad ditiona l lights or accessories
in front of the air inlets reduces the coo l­
ing effect of t he radiato r. At high o utside
tempe rat ures or h igh engine load, the
eng ine could overheat.
- The front spoiler has been designed to
properly d istribute the cooling a ir when
the vehicle is movi ng. If the spoiler is
damaged, this could reduce the coo ling
e ff ect a nd the eng ine could then ove r­
heat . As k yo ur au thori zed A udi deal er for

.&_ 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, especially bridges
and overpasses, could be ice covered and
slippery even at an outside temperature
above 41 °F
(+S 0
().
-Always remember, even if the "snow­
flake" symbol (ice warning) does not ap­
pear in the display, black ice could be on
the road .
- Always reduce your speed and drive with
special care in cold weather conditions
when the chance of encountering icy
road surfaces increases.
@ 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
temperature. This is caused by the heat
being radiated from the engine.
- On vehicles with Audi Nav igation sys­
tem*, the displays may differ from their
normal appearance during navigation.
