The instrument  illumination  (for  dials  and 
needles)  turns on  when  the  ignition is  on 
and  the  vehicle  lights  are  turned  off.  As 
the  daylight  fades, the  illumination  of  the 
dials  likewise  dims  automatically  and wil l 
go  out  completely  when  the outside  light 
is very  low. This feature  is  meant  to  rem ind 
you  to  switch  on  the  headlights  when  out
side  light  conditions  become  poor. 
Engine coolant temperature  gauge 
The  engine  coolant  gauge CD¢ page  11,  fig.  3 
only  works  when  the  ignition  is on.  To prevent 
damage  to your  eng ine,  please  note  the fol
l owing  important  points: 
Engine cold 
If only the LEDs at  the  bottom  of  the  gauge 
turn  on,  the  eng ine has  not  reached  operating 
temperature  yet . Avoid high  engine  speeds, 
heavy  engine  loads  and  heavy throttle  applica
tions. 
Normal  temperature 
The engine  has  reached  its  operating  temper
ature  once  the LEDs  up to  the  center  of  the 
gauge  turn  on  under  normal  driving  cond i
t ions.  The LEDs  higher up  may  turn  on  when 
the  engine  is  under  heavy  load  or  the  exterior 
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  disp lay and  the  indica
tor  light . in the  instrument  cluster  display 
turn  on,  the coolant  temperature  is too  high
