Operation
The shift-up indicator is fitted to cars with manual transmissions delivered to the U.S.A. market. The shift-up indicator enables the driver to use the
engine characteristics in the best possible manner, thus minimising the fuel consumption. Indication is provided by a lamp which lights up when the
driver should shift up, i.e. when the engine speed and throttle setting have attained certain values.
The shift-up indicator receives its supply from fuse 4 when the ignition switch is in the drive position. Shift-up indicator relay 270 receives
information on the engine speed from ignition coil 5 (1985 models) or from ignition pulse amplifier 147 (1986 models). Vacuum switch 263 provides
information on the vacuum in the intake manifold.
When the engine speed has exceeded 1800 + 100 r/min and the vacuum is about 0.3 bar, lamp 47K in the combined instrument will light up.
To avoid incorrect indications, the system is equipped with the following switches:
Switch 264, which switches out the system when 5th gear is engaged.
Temperature switch 262, which switches out the system when the engine temperature is below about +35 °C.
Throttle contacts 203/261, which switch out the system when the throttle is in the rest position.
