Toyota Land Cruiser Prado Forum : “Please tell me the function of 2nd start button”

Dunno, but if you have an owners manual it should say.

It is for starting off in second gear. If you require a greater amount of torque so your wheels do not spin.

it is a back up in case the keyswitch goes bad,same back up is on the 4- runner.

It is for starting off in second gear. If you require a greater amount of torque so your wheels do not spin. I used it and it helped when my Prado got stuck in sand dunes. Normally, the car try to start in second gear, and if for example your car is stuck in Ice, first gear will cause the wheels to spin, so in this situation, second start will assist as it will transfer the power to the wheels very smoothly, thus preventing them from spinning. I hope you understand.
