Learn to drive on the first mission in Sao Paulo, Brazil. Then after Soundwave tells you that you are finished, go forward but to the right behind Grindor and Sideways. Now go to the water's edge and you will encounter an invisible wall. Keep moving left along that wall until you hit the corner by the rock. Slowly pivot around on that point until you are facing directly at the yellow highlighted area where you were going to meet the Decepticons. When you now go forward and come out of the actual water the ground will look like the sky.
