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 229.
-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 N
8 turn on under normal driving conditions. The 0
3 Cockpit overview
LEDs higher up may turn on if the engine is under
heavy load or the outside temperature is high.
This is no cause for concern as long as the. in­
dicator light in the instrument cluster does not
turn on. If the LEDs in the upper area of the dis­
play and the. indicator light in the instrument
cluster display turn on, the coolant temperature
is too high
c::> page 31.
(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.
(D 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 .
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 permitted engine speed
for all gears once the engine has been broken in
and when it is warm . 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 accelerator pedal.
{Q) Note
The needle in the tachometer @c::> page 10,
fig. 3
or c::> page 10, fig. 4 may only be in the
red area of the gauge for a short time or there ..,.

Cockpit overview
If the light does not turn off after starting the
engine
or turns on while driving, this may indi·
cate that there is a malfunction in the eng ine. If
the indicator turns on , the catalytic converter
may be damaged.
Drive
with reduced engine performance (avoid
h ig h speeds for extended periods of time and/ or
fast acce leration) and have the malfunction cor­
rected. See an authorized Aud i dealer or author­
ized Audi Service Fac ility .
The electronic speed limiter may be faulty if the
indicator light turns on. For additional informa­
tion, refer to
¢ page 93, Electronic speed limit­
er .
The MIL indicator light may also turn on if the
fuel filler cap is not closed correctly
¢page 298.
On-Board Diagnostics
Fig . 24 Locat ion of Data Link Connector (D LC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
signed a code . In case of a malfunction, the com­
ponent w ill be identified and the fault stored as a
code in the control module memory.
The MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery system .
If the light illuminates after a refuel ing, stop the
veh icle and make sure the fue l filler cap is prop­
erly closed (on ly vehicles with gasol ine engine)
¢page 298.
In order to make an accurate d iagnosis, the stor­
ed data can only be disp layed using specia l diag­
nostic equipm ent (ge ne ric scan tool for OBD) .
26
In order to connect the special diagnostic equip­
ment, push the plug into the Data Link Connector
(DLC). The DLC is located to the r ight of the hood
release
¢ fig. 24.
Your authorized Audi dea le r or qualified work­
shop can interpret the code and perform the nec­
essary repair.
_& WARNING
Do not use the diagnostic connector for per­
sonal use. Incorrect usage can cause malfunc­
tions, which can increase the risk of a colli­
sion!
