& WARNING
Do not assume the roads are free of ice based
on the outside temperature display. Be aware
that there may be ice on roads even when the
outs ide temperature is around 41 °F ( +S °C)
and that ice can increase the risk of accidents .
@ Tips
-Depending on vehicle equipment, the in­
strument illumination (needles and gauges)
may turn on when the lights are off and the
i gnition is sw itched on . The illumination for
the gauges reduces automat ically and even ­
tually turns off as brightness outside in­
creases . This funct ion reminds the driver to
turn the low beams on at the app ropr iate
time .
- You can se lect the u nits used for tempe ra­
tu re , speed and othe r measureme nts in the
Infotainment system¢
page 249.
-If your vehicle is stationary or if yo u are driv­
i ng at very low speeds, the temperat ure dis­
played may be s ligh tly higher than the ac­
tua l tempe ra ture outside due to the heat ra ­
diating from the engine.
- At temperatures below 41 °F (+S °C), a
snowflake symbol appears in front of the
temperature display¢.&. .
Coolant temperature indicator
The coolant tempe rature display (D ¢ page 10,
fig . 3
or ¢ page 10, fig. 4 only funct ions when
the ignition is switched on . To prevent engine
damage, please observe the follow ing notes
about t he temperature ranges.
Cold r ange
If only the L EDs at the bottom of the gauge turn
on, the engine has not reached operating tem­
perature yet . Avo id h igh engine speeds, full ac ­
celerat ion and heavy engine loads .
Normal range
~ The engine has reached its operating temper a-,.....
~ ture once the L EDs up to the center of the gauge
8 turn on . If the . indicator light in the instru-o :E: ' Coc kpit o ve rv iew
ment cluster d isp lay turns on, the coo lant tem ­
peratur e is too high
¢ page 26.
(D Note
-Aux iliary headlights and ot her a ccesso ries in
front o f the coo ling -air intake impa ir the
cooling effect of the coolant . This increases
the risk of the engine overheating dur ing
high outside temperat ures and heavy en­
gine load.
- The front spoiler a lso helps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the r isk of the eng ine over ­
heating will increase . See an authorized
Audi dealer or author ized Audi Service Fa­
cility for assistance .
@ Tips
Diesel engines: due to the h igh efficiency of
these engines, the engine may not a lways
r each operat ing temperatu re in cold outside
temperat ures . This is norm al and no t a cause
f or concern.
Tachometer
The ta chometer displays the engine speed in rev­
olutions per minute (RPM).
T he beg inning of t he red zone in the tachometer
indica tes the maxim um permissible engi ne speed
f o r all gea rs once the engi ne h as bee n broken in.
Be fore reach ing t his zone, you shou ld shift into
the next h ighest gear, select the D/S se lector lev­
er posit io n, or remove yo ur foot from the acc eler­
ator pedal.
(D Note
The need le in the tachometer @¢ page 10,
fig . 3
or ¢ page 10, fig . 4 may on ly be in t he
r ed area of the gauge for a sho rt time or there
i s a risk of engine damage . The location where
the red zone begins varies depending on the
engine.
