Voltmeter
(Turbo-engine cars only)
The voltmeter indicates the voltage in the electrical system and thereby also the state of the battery. While the car is
being driven the pointer should be within the black field. Should the pointer point to the upper or lower red field when
driving, this may indicate some fault in the electrical system.
Boost gauge
( Turbo-engine cars only )
The boost pressure gauge is divided into sections.
Black section : The engine acts as a normally-aspirated engine. Best fuel economy is achieved while driving in this
range. Yellow section: The turbo is providing boost pressure.
