Simply in 3 quick actions (all buttons are defined by default):
- A/ Crouch & run (on the ground) [Press "Shift" and "Z" ]
B/ Jump (arched backwards ) [always "Z" button pressed: now release "Shift" & press "Spacebar"]
C/ Crouch (magnetize the wall)[always "Z" button pressed (or not): now release "Spacebar" & press "Shift"]

In details:
- On the ground: taking enough distance (of at least the size of a vehicle) relative to the forward wall; preparing the jump: press "crouch" to lower the vehicle, then move towards to the wall; jump: at a distance of a half-vehicle: release the "crouch" and press "space" to make one jump-arched backwards; finaly magnetize: the vehicle -in vertical position at present wheel on the wall- release the "space" & magnetize the wall with "crouch" and run!
Now: your turn to understand how to access a horizontal surface :}
Note: it's impossible to magnetize ceilings (the véhiciles are too heavy).
I hope this topic help somebody, demand me here if U've any question
