CAUTION:
lWhen removing accelerator cable, mark location to indicate lock nut's initial position.
lCheck that throttle valve is completely open when accelerator pedal is fully depressed. Check
that throttle valve returns to idle position when accelerator pedal is released.
lCheck accelerator control does not interfere with any adjacent parts.
lWhen connecting accelerator cable, be careful not to twist or scratch cable.

OUTLINE OF MODIFICATIONS
GENERAL
lVarious running changes on engine control system, electrical systems, body etc. Note that the introduc-
tion timing of some of the running changes may not be entirely in line with the above mentioned VIN.
lFor some running changes, the VIN (Vehicle Identification Number) is mentioned to specify the timing
of the change implemention.
The VIN No. may not be an exact number, there is an error range of approx.  50 cars.
