The instrument  cluster  illuminates  whenever  you  switch  on  the  igni
tion  with  the 
vehicle  headlights  off. The  instrument  cluster  illumina 
tion  dims  automatically  as the  daylight  begins  to  fade  away.  It goes 
out  completely  when  the  outside  light is very  dim.  The  reason  for 
this  is to  remind  you  to  turn  on  the  headlights  when  the  light  condi
tions  become  poor. • 
Engine  coolant  temperature  gauge 
The engine  coolant gauge~ page  12, fig.  2 G) only  works  when  the 
ignition  is  on . To prevent  damage  to  your  engine,  please  note  the 
following  important  points: 
Engine  cold 
As  long  as  the needle  remains  at  the left  end  of the  gauge,  the 
engine  still  has  not  reached  its  operating  temperature . Avoid  high 
engine  speeds,  heavy  engine  loads  and  heavy  throttle. 
Normal  temperature 
When  the  engine  has reached  its  operating  temperature, the needle 
will  move  into  the  middle  of  the  gauge  and  remain  there.  If the 
engine  is working  hard  at  high  outside  temperatures,  the needle 
may  turn  further  to  the  right . This  is no cause  for  concern  as  long as 
the 
- F-warning  light  in  the  instrument  cluster  does  not  illuminate. 
When  the 
-L warning  light starts  to  flash,  this can mean  one of  two 
things:  either  the  coolant 
temperature is too  high,  or  the  coolant 
level is too  low~ page  31. 
_& WARNING 
• Always  observe  the  warning  in ~ page  242, "Engine  compart
ment"  before  opening  the  engine  hood  and  checking the  engine 
coolant  level. 
•  Never  open  the  engine  hood  if you  see or  hear  steam,  or  if you 
see engine  coolant  dripping  from  the  engine  compartment.  You

ment

& WARNING  (continued) 
could burn yourself.  Let the  engine cool off first  so that  you cannot 
hear  or  see any steam  or  engine  coolant. 
0 Note 
•  Mounting  additional lights or accessories  in front  of  the air  inlets 
reduces  the  cooling  effect  of  the  radiator.  At  high  outside  tempera
tures  or high  engine  load,  the engine  could  overheat. 
•  The  front  spoiler  has  been  designed  to  properly  distribute  the 
cooling  air  when  the vehicle  is moving.  If  the spoiler  is damaged, 
this  could  reduce  the  cooling  effect and  the  engine  could  then  over
heat.  Ask your  authorized  Audi  dealer  for assistance. • 
Tachometer  (engine  rev  counter) 
The tachometer  indicates  the  engine  RPM (revolutions  per 
minutes). 
The  tachometer ®~ page  12, fig.  2 is the  left one  of  the two  large 
clock -type  displays. 
The  engine  turns at  a speed 
1,000 times the  single  digit in  the 
display,  e.g.  if  the  needle  points  at the  "2",  the  engine  turns  at 
2,000  RPM. 
If the  engine  RPMs drop  below  1,500, you  should  downshift to the 
next  lower  gear. The red  area  at  the  end  of  the  scale  indicates 
maximum  permissible  engine  RPMs after  the  break-in period. 
Before  reaching  this  area,  you  should  either  shift  into  the  next 
higher  gear or ease your  foot off  the  accelerator  pedal. 
0 Note 
The  tachometer  needle  should  not move into the  red  range. If it 
does,  then  only  for  a very  short  period  of  time.  You could  damage 
your  engine  by  driving at high  RPM!  _.
