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
Camera-based traffic
sign recognition
Description
Applies to: vehicles with camera-based traffic sign recogn i­
tion
F ig. 21 Instrument cluster: traffic sign recognition
Fig. 22 Windshield: camera window fo r tra ffic sign recog­
nit ion
Traffic sign recognit ion assists you when driving
by displaying detected speed limits or signs pro­
hibiting passing in the instrument cluster disp lay
~fig . 21. Within the limits of the system, the le­
gal speed limits in school zones are detected and
displayed.
General information
Traffic sign recognit ion can detect standard
speed limit signs that are within the camera's vis­
ual field. With assistance from navigation data,
detected speed limits are evaluated and shown in
the display. The traffic sign for the current de­
tected speed limit will blink in the display if you
exceed the warning threshold set in the Infotain­ ment system
~ page 2 5 .
The traffic sign recognition is subject to certain
system limitations and may be unavailable or on­
ly partially available in the following situations:
24
-when visibility is poor, such as in snow, rain,
fog or heavy spray .
-when there is glare, for example from oncom­
ing traffic or the sun.
- at high speeds.
- if the camera's visual field
~ fig. 22 is covered,
for examp le by dirt or st ickers. For info rmation
on cleaning, refer to
c::> page 33 7.
- if the traffic signs are completely or partially
covered, for examp le by trees, snow, dirt or
other vehicles.
- if speed traffic signs do not conform to the
standards.
- if traffic signs are damaged or bent.
- if traffic signs are d isplayed on sign holders
w ith electronic signs.
- if the traffic signs or the configuration of the
road have changed (navigation data is no lon­
ger up-to-date) .
.&_ WARNING
Pay attention to traffic and the area around
your vehicle when traffic sign recognition is
turned on . The traffic signs installed on the
road always take precedence over the display.
The driver is always responsible for correctly
assessing the traff ic situation.
- Under some circumstances, traffic sign rec­
ognition may not detect traffic signs cor­
rectly or detect them at all. As a result, the
system may not display the correct speed
lim it or any speed limit.
- Traff ic sign recognit ion does not adapt your
veh icle's speed to match the speed limit!
- The display in the instrument cluster is
based on the units of measurement used for
speed in that country. As a result, the dis­
play
SO in the instrument cluster can mean
eithe r km/h or mph, depending on the coun­
try.
