FULL 0.5-2.5 R
112 20.7-24.7 R
The low fuel warning light operates as follows:
The combination meter CPU continually monitors the resistance signal from the fuel level sensor.
It turns on the low fuel warning light if a resistance value corresponding to the critical fuel level
(approx. 78 R) is detected successively for about 10 minutes or the period spent for driving a dis-
tance of 10 km.
This monitoring time has been decided to avoid false operation of the warning light which may
happen when a large part of remaining fuel is collected temporarily in the sub tank compartment.
