the cps AT is equipped with intelligent sensor... "kick down" is similar like you manually change from D to 3 or 2...
the sensor will detect the sudden increase and compare it with current speed... it shift down to produce more torque...
that is why cps AT dont have any overdrive button (like myvi)
although cornering is not my cup of tea, it is normal for AT to drop gear depending your entry and exit speed...
if you are slowing down before entering a corner and pressing the pedal forcefully while exiting, the AT sensor will immediately deliver more torque by shifting down...
there is one high speed corner in putrajaya that i usually brake while entering the corner not before it and let lotus-tuned suspension perform the handling at its best...
i'm not sure about the right way to drive an AT car but from what i learned (fuel efficient drive):
1. we should be more gentle controlling the acceleration (try watch initial d 4th stage to understand the concept)
2. control when and where to brake ( unlike manual, AT will consume more fuel if you tend to brake a lot)
I learned this from those who drove perdanas for international events like NAM, ASEAN, etc and VIP chauffer
My best with CPS was 570km (from full tank till the first light came out)
myvi does have overdrive button...
...how much u corner? 100km?..hw sharp?..
