Cockpit overv iew
CD Note
-Auxiliary headlights and other accessories in
front of the cooling-a ir intake impair the
cooling effect of the coolant. This increases
the r isk of the engine overheat ing during
high outside temperatures and heavy en-
gine load.
- The front spoiler also he lps to distr ibute
cooling air correctly wh ile driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over­
hea ting will inc re ase. See an a uthorized
A udi dealer or au thori zed A udi Service Fa­
cility for assistance .
Tachometer
The tachometer display s the engine speed in rev­
olutions per minute
(RPM).
You shou ld shift to the nex t lowest gea r whe n
the speed is below 1,500 R PM. The beginn ing of
the red zone in the t achometer indic ates the
maxim um permissible eng ine speed fo r all gears
once the engine has been broken in an d when it is
warmed up to operating temperature . Before
reaching this zone, you should shift into the next
h ighest gear, select the D selector lever pos ition,
or remove your foot from the accelerator pedal.
CD Note
The needle in the tachometer @ <=:> page 9,
fig. 3 may only be in the red area of the gauge
for a short t ime or the re is a risk of engine
damage. The locat ion where the red zone be­
gi ns varies depending on the engine.
@ For the sake of the environment
Upshifting early helps you to save fuel a nd re­
duce operating noise.
Fuel level
The display ® only works when the ignition is
sw itched on. If the fuel level d rops below 4 gal
(15
L), a red L ED will light up and the ll) ind ica­
tor light will tur n on
