Gear Shift Indicator
The instrument cluster shows the actual gear currently
selected R, D1, D2, etc and the target gear when a
gearshift is in progress.
The instrument cluster will also show an up arrow to
indicate when a gear change should take place to obtain
better fuel economy. For example, when in seventh gear
and a higher gear needs selecting, 7^ is shown.
