Go to Youku and find a radish to report. There is a video about Qi Jun climbing Hero Slope. There are detailed steps to start the four-wheel drive. This four-wheel drive is designed to take a bad road. It is strong in off-road vehicles, but it can't be compared with hard-core off-road vehicles. Don't lock Panshan Highway when the road conditions are good, it's just a waste of gasoline. You can use it if you can't pass by. Hard-core off-road vehicles, four-wheel drive locked can not turn. Remember.
