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

(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 .
Shift indicator
Applies to veh icles: w ith shift indicator
This indicator can help conserve fuel.

When the selector lever is in D/S, the S tronic
transmission shifts up or down automat ica lly.
If you wish to shift the gears manually
¢ page 110, Shifting manually (tiptronic

mode), then the shift indicator can assist you
when selecting the next gear.
I n order to become familiar with the gearshift
indicator, begin driving as usual.
If the current
gear is not the best one for conserving fuel,
the indicator wi ll display the recommended
gear.
If there is no gearshift recommendation, you
are already driving in the most suitable gear .
The display is only vis ible in tip tronic mode

The service interval display works in two
stages:
- Inspection or oil change reminder: After a
specified number of miles, a message ap­
pears in the instrument cluster display when

due!.
Checking service intervals
The remaining distance or t ime to the next oil
change or to the next inspect ion can be
viewed in the MMI
c::>fig. 8. Selectthe ,...IM""" E~ N- u-1
button
> Systems or Car systems > Service &
control > Service intervals.
In new vehicles or after resetting the disp lay,
the display can be viewed after approximately
500 km.
Resetting the display
Your authorized Audi dealer or qualified facili­
ty will reset the service interval display after
the service is performed.
If you perform an oil change yourself to the
Audi specifications, you can reset you service
interval display.
To reset the display, select the !MENUI button

14 Instruments and indicator lights
> Service intervals > Reset oil change inter­
val.
(D Note
- Only reset the oil change disp lay w hen
you have completed an o il change .
- Maintain ing the service intervals is of vi­
ta l importance for the life and value of
you r vehicle espec ially the engine . Serv­
ice interva ls shou ld not be exceeded,
even by a short distance .
- If the vehicle battery is disconnected,
the timing for the next oil change wi ll be
i nterrupted.
If the vehicle is stationary
for a long time, have all scheduled serv­
ices performed.
- Even if the mileage driven is low, the
maximum period of one year from one
service to the next must not be exceed­
ed.
