-Never open the  engine  hood  if  you see or 
hear steam,  or  if  you see engine  coolant 
dripping  from  the  engine  compartment. 
You could  burn yourself . Let the  engine 
cool off  first  until  you  can no longer  see 
o r  hear steam  or  coo lant  escaping. 
@ Note 
- Mounting  additional  lights  or  accessories 
i n 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  could  overheat. 
- The front  spo iler  has been designed  to 
proper ly distribute  the  cooling  air when 
t h e ve hicle is moving. 
If the  spoiler  is 
dam aged,  th is co uld  red uce the  cooling 
effect  and the  engine  co uld  then  over
heat . Ask your  authorized  Audi  dea ler for 
assistance . 
Tachometer  (engine  rev counter) 
The tachometer  indicates  the  engine RPM 
(revolutions  per  minutes). 
If engine  RP M drops be low  1,500,  yo u should 
downshift  to  the  next  lower  gear.  The red a rea 
at  the  end of  the  sca le indicates  maximum 
perm iss ib le engine  RPM after  the  break-in  pe
riod.  Before  reaching this  area, move these
lector  lever to  position  D/S (Drive) or  ease 
your  foot  off  the  accelerator  pedal. 
(D Note 
The tachometer  needle  should  on ly br iefly 
be in  the  red zone: you  could  damage your 
engine!  The beginn ing of  the  red zone var
ies depending  on the  engine . 
@ For the  sake of the  environment 
Upshifting early saves fuel  and  reduces en
gine  noise. 
Fuel gauge 
The fuel  gauge  only works  when  the  ignition  is 
on . 
If the  fuel  level  d rops below  2 . 6 ga llons  (10  liters),  the  bottom  LED turns  red and the 
indicator  light 
Em turns  on
¢ page 22. The 
bottom  LED blinks  red when  the  fuel  level  is 
very  low. 
T he possible  range based on the  current  fuel 
level  is shown  in  tab@<=> 
page  24,  fig . 4 . 
(D Note 
Never run  the tank  completely  dry.  An ir 
r egular  supply  of  f uel  can cause engine 
misfiring  and fuel  could  enter  the  ex ha ust 
system . The catalytic  converter  could  then 
overheat  and  be damaged.
