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.
@ 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
c::> page 248.
- 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
c::> A .
Coolant temperature indicator
The coolant temperature
display @c::> page 10,
fig. 3 or c::> 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.
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-
Cockpit overview
ment cluster display turns on, the coolant tem­
perature is too high
c::> page 30.
(D 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 .
@ Tips
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.

On-Board Diagnostics
Fig. 22 Location of Data Li nk Con nec tor (DLC )
On-Board Diagnostics monitors the components
of your em ission control system. Each monitored
component in your eng ine system has been as­
signed a code. In case of a ma lfunction, the com­
ponent will be identified and the fault stored as a
code in the control module memory.
The MI L light may also illuminate if there is a
leak in the on -board fuel vapor recovery system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel filler cap is prop­ erly closed (only vehicles with gasoline engine)
¢ page 317 .
In order to make an accurate diagnosis, the stor­
ed data can only be displayed using special diag­ nostic equipment (generic scan tool for OBD) .
In order to connect the specia l diagnostic equip­
ment, push the plug into the Data Link Connector
(DLC). The DLC is located to the right of the hood
