INVECS-III CVT is still CVT(using torque converter)!
It's correct to drive your vehicle using D Mode after a complete stop. Trying to understand INVECS-III CVT how to work, then you wouldn't shift into "Sports Mode" to keep vehicle stopping on an uphill.
The “Sports Mode” is not a really MT(Manual Transmission).
p.s. SST is better than CVT, and thanks gladiator for translation.
