I dunno whether i shld be the one who shld LOL... Perhaps u shld
get your facts right first b4 LOL...
The "hold" button is equivalent to overdrive...
When overdrive is off, the car will not be able to shift up to its
most efficient gear, which is the 4th gear for 4AT cars... It is
the same when u the hold button is on...
Juz click the button when u want to overtake, the gear will drop
from 4 to 3 immediately, the reaction is faster than when u fully
depress the accelerator pedal to downgear...
