Tachometer
The tachometer shows the number of engine rev­
olutions per minutes .
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
and when it is warm. You should select the "0/
S" (Drive) selector leve r position or take your foot
off the accelerator pedal before reach ing th is
area.
It is best to avoid high engine speeds, even when
driving in tiptronic mode
<=> page 87.
(D Note
The tachometer needle © c::> page 10, fig. 3
should only be in the red zone briefly:
@ For the sake of the environment
Upshifting early helps you to save fuel and re­
duce operating noise .
Odometer
Fig. S Instrument cluster : odo meter and reset button
The distance driven is shown in miles "mi" or kilo­
meters "km". The measuremen t units (miles
"mi"
I kilometers "km") can be changed in the
MMI. For more information, refer to your MMI
operat ing instructions .
Odometer/trip odometer
@-The odometer shows the total distance that
the vehicle has been driven .
@-The trip odometer shows the distance that
the vehicle has been driven since the last time
the trip odometer was reset. It can be used to
Instruments and indicator lights
measure short distances. The last digit indicates
1/10 mi les or 100 meter increments.
T he trip odometer can be reset to zero by press­
ing the
10.01 button <=> page 10, fig . 3.
Malfunction indicator
If there is a malfunct ion in the instrument clus­
ter,
DEF will appear in the tr ip odometer display .
Have the malfunction repaired as soon as poss i­
ble.
@ Tips
- When you switch the ign ition off or open
the driver's door, the odometer is disp layed
for approximately 30 seconds.
- You can also turn on the display with the
!O .O I button when the ignition is switched
off c::>
page 10, fig. 3.
Outside temperature display
The instrument cluster display shows the outside
temperature . At temperatures below 41 °F
(+ S °C), a snowflake symbol appears in front of
the temperature display .
If your vehicle is stationary or if you are driving at
very low speeds, the temperature displayed may
be slightly higher than the actual temperature
outside due to the heat radiating from the en­
gine.
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 °()
and that ice can increase the risk of accidents.
@ Tips
You can change the measurement un its, for
example for temperature or speed, in the
MMI.
Fuel level
The display @ c::>page10, fig. 3 on ly works when
the ignition is switched on. When the display has .,.
11

Instruments and indicator lights
reached the reserve mark, the bottom LED will
turn red and the
ljJ indicator light turns on
¢
page 23. The bottom LED blinks red when
the fuel level is very low.
The on-board computer shows the range based
on the fuel level¢
page 28, On-board comput­
er display.
For the tank capacity in your vehicle, refer to the
Technical Data
¢ page 260.
(D Note
Never drive until the tank is completely emp­
ty. The irregular supply of fuel that results
from that can cause engine misfires. Uncom­
busted fuel will then enter the exhaust sys­
tem. This can cause overheating and damage
to the catalytic converter.
Coolant temperature indicator
In vehicles without a coolant temperature indica­
tor, an indicator light. will turn on when the
coolant temperature is too high ¢
page 19. Re­
fer to ¢(1) .
The coolant temperature indicator @c:>
page 10,
fig . 3 only works when the ignition is switched
on . To prevent engine damage, please observe
the following notes about the temperature rang­
es.
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 accel­
erating 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 under normal driving conditions . The
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.
12
Hot range
If the LEDs in the upper area of the display and
the . indicator light in the instrument cluster
display turn on, the coolant temperature is too
high
c:> page 19 .
A WARNING
-Never open the hood if you can see or hear
steam or coolant escaping from the engine
compartment. This increases the risk of
burns. Wait until you no longer see or hear
steam or coolant escaping.
- The engine compartment in any vehicle can
be a dangerous area . Stop the engine and al­
low it to cool before working in the engine
compartment. Always follow the informa­
tion found in ¢
page 198, Working in the
engine compartment.
(D Note
- In vehicles with a boost pressure indicator* ,
this indicator replaces the temperature dis­
play. To promote a long engine service life,
avoiding high engine speeds, full accelera­
tion and heavy engine loads during approxi­
mately the first 15 minutes when the en­
gine is cold is recommended . The amount of
time until the engine is warm depends on
the outside temperature . Check the engine
oil temperature* if necessary .
c:> page 30
-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 engine
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.

!7l Engine speed limitation
A pplies to vehicles: with eng ine spee d limitat ion
(II Ma x. engine speed: XXXX rpm
The engine speed is automatically limited to the
speed displayed in the driver information system.
This protects the engine from overheat ing .
The engine speed limitation deactivates once the
engine is no longer in the critical temperature range and you have released the accelerator ped­
al once.
If the engine speed limitation was activated by
an engine control malfunction, the~ indicator
light also turns on . Make sure the engine speed
does not go above the speed d isplayed, for exam­
ple when downshifting. Drive to an author ized

System indicator light (MIL)
The system indicator light (MIL) ¢4 in the instru ­

System (OBD II).
The warning/indicator light turns on when the ig­ nition is switched on and turns off once the en­
gine is started and is running in idle at a stab le
speed. Th is ind icates that the MIL is funct ion ing
correctly .
If the light does not turn off after starting the
engine
or turns on while driving, this may indi­
cate there is a ma lfunction in the engine. If the
Instruments and indicator lights
indicator turns on, the cata lytic conve rter may be
damaged.
Drive
with reduced engine performance (avoid
high speeds for extended per iods of time and/or
f ast acceleration) and have the malfunction cor­
rected . See an authorized Audi dealer or author­
ized Audi Serv ice Facility.
T he indicator may turn on if the e lectronic speed
limiter is faulty. For add itiona l information, refer

On-Board Diagnostics
Fig. 7 Location of Data Link Connector (DLC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
s igned a code . In case of a mal function, the com­
ponent will be identified and the fault stored as a
code in the control module memory.
T he M IL light may also illuminate if there is a
leak in the on-board fuel vapor recove ry system.
If the light illuminates after a refuelling, stop the
vehicle and make sure the fuel filler cap is prop­
erly closed
qpage 192.
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 special diagnostic equip­
ment, push the plug into the Data Link Connector
(DLC). The DLC is located to the right of the hood
