A 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
outside temperature is around 41 °F (+5 °C)
and that ice can increase the risk of accidents .
(D Tips
- Depending on vehicle equipment, the in-
strument illumination (needles and gauges)
may turn on when the lights are
off and the
ignition is switched on . The illumination for
the gauges reduces automatically and even-
tually turns off as brightness outside in-
creases. This function reminds the driver to
turn the low beams on at the appropriate
time.
- You can select the units used for tempera-
ture, speed and other measurements in the
Infotainment system ¢
page 245.
- If your vehicle is stationary or if you are driv-
ing at very low speeds, the temperature dis-
played may be slightly higher than the ac-
tual temperature outside due to the heat ra-
diating from the engine.
- At temperatures below 41 °F (+5 °C), a
snowflake symbol appears in front of the
temperature display ¢ ,&..
Coolant temperature indicator
The coolant temperature display @ ¢ page 10,
fig . 3
or ¢ page 10, fig . 4 only functions when
the ignition is switched on. To prevent engine
damage, please observe the following notes
about the temperature ranges.
Cold range
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem-
perature yet . Avoid high engine speeds, full ac-
celeration and heavy engine loads.
Cockpit overview
Normal range
The engine has reached its operating tempera-
ture once the LEDs up to the center of the gauge
turn on. If the. indicator light in the instru-
ment cluster display turns on, the coolant tem-
perature is too high ¢
page 22.
@ Note
- Auxiliary headlights and other accessories in
front of the cooling-air intake impair the
cooling effect of the coolant. This increases
the risk of the engine overheating during
high outside temperatures and heavy en-
gine load .
- The front spoiler also helps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over-
heating will increase. See an authorized
Audi dealer or authorized Audi Service Fa-
cility for assistance.
{D Tips
Applies to: vehicles with diesel engines
Due to the high efficiency of these engines,
the engine may not always reach operating
temperature in cold outside temperatures.
This is normal and not a cause for concern.
Tachometer
The tachometer displays the engine speed in rev-
olutions per minute (RPM).
The beginning of the red zone in the tachometer
indicates the maximum permissible engine speed
for all gears once the engine has been broken in.
Before reaching this zone, you should shift into
the next highest gear, select the "D/S" selector
lever position, or remove your foot from the ac-
celerator pedal.
@ Note
The needle in the tachometer @ ¢ page 10,
fig. 3
or ¢ page 10, fig. 4 may only be in the
red area of the gauge for a short time or there
is a risk of engine damage . The location where .,.
