You should rather use OnPlayerEnterVehicle callback for this, since you're relating this completely to vehicles.

public OnPlayerEnterVehicle(playerid, vehicleid, ispassenger)
{
    if(GetVehicleModel(vehicleid) == 416)
    {
        SendClientMessage(playerid,Red,"Type /paramidc to start job");
    }
    return 1;
}
