The ratio of the distance driven using only power charged from an
external power source against other driving conditions is displayed
on the EV driving ratio screen. Two separate EV driving ratios can be
used: EV driving ratio (1) and EV driving ratio (2).
On the plug-in effect screen, the amount of CO
been reduced by repeatedly recharging from an external power
source is symbolized by adding trees, flowers and animals to the dis-
play.
Calculation can be started or finished at any time via the reset operation.
