- When switching the ignition on, the nee­
dles in the instrument cluster swing 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 a nd will go out completely
when the outside light is
very low. This
feature is meant to remind you to switch
on the headlights when outside light
conditions become poor .
Engine coolant temperature gauge
The engine coolant gauge q page 10, fig. 3 CD
only works when the ignition is on. To prevent
damage to your engine, please note the fol ­
lowing important points:
Engine cold
If the needle is at or close to the bottom of
the gauge, the engine has not yet reached its
operating temperature. Avoid high engine
speeds, heavy engine loads, and heavy throt ­
tle app lications.
Normal temperature
When the engine has reached its operating
temperature, the needle will
move to the mid­
dle of the gauge and remain there . If the en­
gine is working hard at high outs ide tempera­
tures, the needle may
move higher on the
gauge. This is not a cause for concern as long
as the . warn ing light in the instrument
cluster display does not illuminate. If the.
warning light in the instrument cluster dis­
play flashes, this can mean one of two things:
either the coolant
temperature is too high, or
the coolant
level is too low¢ page 17 Ill-

A WARNING
- Always observe the warning in
c::> page 195 , 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).
I f 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.
