The  instrument  illumination  (for  dia ls and 
needles)  t urns on when  the  ignition  is  on 
a nd the  vehicle  lights  are tur ned off.  As 
the  daylight  fades,  the  illumination  of  t he 
dia ls likewise  dims  automatica lly and w ill 
go o ut  comple tely when  the o utsi de light 
i s  very  low. Th is feature  is meant  t o rem ind  you 
to sw itch  on the  head ligh ts when  o ut
s id e light  condi tions  become poor . 
Engine  coolant  temperature  gauge 
The engine coolant  gauge (!) ¢ poge 10, fig. 3 
only works  when the  ignition  is  on. To prevent 
damage  to your  engine,  please note  the fol
lowing  important  po ints: 
Engine  cold 
If only  the  LEDs at  the bottom  of  the  gauge 
turn  o n, the  engine has not  reached operating 
temperature  yet.  Avoid hig h engine  speeds, 
heavy engine  loads and  heavy  throttle applica
tions . 
Normal  temp erature 
The eng ine has reached  its  operating  temper-
at ure once the  LEDs up to  the  center  of  the  .,.  
Page 13 of 314

Instrument s and  warnin g/indic ator  ligh ts 11 
gauge turn  on under  normal  d riving  condi 
tions . The LEDs higher  up may turn  on when 
the  eng ine  is under  heavy  load or the  exter ior 
temperature  is high . This  is no need to  worry 
as long  as  the. warning  light  in the  instru
ment  cluster  does not  illuminate . If  the  LEDs 
in the  upper  area of  the  display  and the  ind ica
tor  light . in the  instrument  cluster  d isplay 
turn  on, the  coolant  temperature  is too  high 
¢ page  16. 
A WARNING 
-Always observe the  warning  in 
~ page  231,  Working  in the  engine 
compartment, 
before  opening  the  hood 
and checking the  engine  coolant  level. 
- Never open the  engine  hood  if you  see or 
hear steam,  or  if  you see engine  coolant 
dr ipping  from  the  engine  compartment. 
You could  burn  yourself.  Let the  engine 
cool off  first  so that  you  cannot  hear or 
see any steam  or  engine  coolant . 
(D Note 
- Mounting additional  lights  or  accessories 
in front  of  the  a ir inlets  reduces the  cool
i ng effect  of  the  rad iator . At  h igh outside 
temperatures  or  high  eng ine load,  the 
engine  co uld  overheat. 
- The front  spo ile r  has been designed  to 
properly  distrib ute  the  cooling  air when 
the  veh icle is moving.  If  the  spoiler  is 
damaged,  this  cou ld red uce the  cooling 
effect  and t he engine  co uld  then  over
heat . Ask your  aut ho rized Audi  dea le r for 
ass istance. 
Tachometer  (engine  rev counter) 
The tachometer  indicates  the  engine  RPM 
(revolutions per minutes). 
If engine  R PM drops be low  1,500,  you should 
downshift  to  the next  lower  gear.  The red a rea 
at  the  end of  the  sca le ind icates maxim um 
perm iss ible engine  RPM after  the  break-in  pe
riod.  Before  reaching this  area, move these
lector  lever to  position  "D (Drive)"  or ease 
your  foot  off  the  accelerator  pedal. 
@ Note 
The tachometer  need le should  only  briefly 
be  in the  red zone: yo u could  damage your 
engine!  The beg inning  of  the  red zone var 
i es dependi ng on the  engine. 
@ For the  sake of  the  environment 
Upsh ifting  early  saves fuel  and  reduces en 
gine  noise. 
Fuel gauge 
The fuel  gauge only  works  when  the  ignition  is 
o n. 
If the  fue l level  drops  below  4  gallons  (15 
l ite rs), the  bottom  LE D tu rns red and the  indi
cator  light~ turns  on 
c::> page  21. The bot
tom  LED b link s red when  the  fue l level  is very 
l ow . 
The possible  range based on the  current  fuel 
level  is shown  in  tab@~ 
page  24,  fig.  4. 
(D Note 
Never run the  ta nk complet ely dry.  An ir
regular  supply  of  f uel  can cause engine 
misfiring  and fuel  cou ld enter  the  exha ust 
system.  The  cata lytic  converter  could  t hen 
overheat  and be damaged .
