Tachometer
The tachometer displays the engine speed in
revolutions per minute .
The beginning of the red zone in the tachome­
ter indicates the maximum permissible en­
g ine speed for all gears once the engine has
been broken in and when it is warmed up to
operat ing temperature. Choose the "D/S "
(Drive) selector lever position or reduce speed
before you reach the red zone .
(D Note
The speedometer needle (D c::> page 10,
fig. 3
should only briefly be in the red
zone: you could damage your engine!
@) For the sake of the environment
Upshifting early helps you to save gasoline
and reduce operating noise.
Odometer
Fig. S Instrument cl uster: odo meter an d reset button
T he distance driven is shown in miles "mi" or
in kilometers "km" . The measurement units
(mi les "mi"/kilometers "km") can be adjusted
i n the MMI. You will find more informat io n on
this in the MMI owner's manual.
Odometer/trip odometer
@-The odometer shows the total distance
that the veh icle has dr iven .
®-The trip odometer shows the distance
driven since the trip odometer was last reset .
It can be used to measure short distances .
The last digit indicates 1/10 mile or 100 me­
ters .
Instruments and indicator lights 11
The trip odometer can be reset to zero by
press ing the button
!O.O ! c::> page 10, fig. 3.
Malfunction indicator
If a malfunction occurs in the instrument pan­
el ,
DEF will appear in the trip odometer dis­
play area. You should have the malfunction
corrected as soon as possible.
a) Tips
- When you switch off the ignition or open
the driver door, the odometer is dis­
played for approximately 30 seconds.
- Yo u can also call up the display with the
!O.O ! button while the ignition is switch ­
ed off
c::, page 10, fig . 3.
Outside air temperature display
The outside air temperature is displayed in the
instrument cluster. At temperatures below
approximately41 °F ( +S °C), a snowflake sym­
bol appears in front of the temperature dis ­
play .
If your vehicle is stationary or if you are driv­
ing at
very low speeds, the temperature d is­
played may be slightly higher than the actual
temperature outs ide due to the heat rad iating
from the engine.
,&. WARNING
Never assume that the streets are free of
ice based on the outside air temperature
display. Please note that there may be ice
when the outside temperature is 41 °F (+S
°C) -there is a risk of an accident due to ice
buildup!
(D Tips
The measurement uni ts, for examp le for
the temperature or speed, can be adj usted
in the MMI.
Fuel level
The display ® c::, page 10, fig. 3 only functions
with the ignition is switched on . When the
display reaches the reserve marking, the
IJJ,,

12 Instrum ent s and indicator ligh ts
bottom LED illuminates red and the indicator
light
ti appears ¢ page 24 . The bottom
LED blinks red when the fuel level is very low.
The poss ible range based on the current fue l
leve l is shown in the on-board computer
¢ page 2 7, On-board computer display .
The fuel tank capacity of your veh icle is in the
techn ica l data ¢
page 266.
(1) Note
Never drive with the tan k completely emp­
ty. An irregu la r fuel supp ly can ca use the
eng ine to misfire. This leads to uncom­
busted fuel in the exhaust system. This
can cause overheating and damage to the
catalyt ic converter.
Engine coolant temperature gauge
The engine coolant temperature gauge@
¢
page 10 , fig . 3 only functions when the ig­
n ition is switched on . To prevent engine dam ­
age, observe the follow ing important points
concerning the temperature ranges.
Cold r ange
If only the LEDs at the bottom of the gauge
turn on, the engine has not reached operat ing
temperature yet . Avoid high eng ine speed, full
throttle, and heavy eng ine load.
Norm al ra nge
The engine has reached its operating temper­
ature once the LEDs up to the center of the
gauge turn on under normal driving condi­
tions . The LEDs higher up may turn on when
the eng ine is under heavy load or the exter ior
temperature is high . Thi s is not a cause for
concern as long as the. indicator light in
the disp lay does not turn on .
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 tempera­
ture is too h igh ¢
page 20.
A WARNING
-Always observe the warn ing in
¢
page 210 before opening the hood
a nd checking the engine coolant level.
- Never open the eng ine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment .
You could bur n yourself. Let the engine
coo l off first u ntil yo u can no longer see
or hear steam or coolant escaping.
([) Note
-Add itional headlights and other compo­
nents in front of the a ir intake reduces
affect of the eff iciency of the coolant. At
hig h ou tside air temperat ures and wi th
heavy eng ine load, there is a ris k of the
eng ine overheating .
- T he front spoiler ensures the correct dis­
tribution of cooling air while driving . If
the spoi ler is damaged, the effect of the
coolant can be reduced and there is a risk
of the engine overheating. See your au­
thorized Audi dealer or qualified repair
facility .
