Terrain Tackling: Rockhopping
For the novice four-wheel driver, rocky terrain is the most daunting and potentially vehicle damaging of all terrains. But it should pose no problem for a lot of 4WDs, Pajero for instance is superbly equipped to carry you through without either your heart in mouth, or your hand in wallet.
You will need low range. In the Mitsubishi Super Select system, unlike the other transmission functions, where you can swap between 2WD, 4WD open centre diff and 4WD high locked centre diff on the move at speeds up to 100km/h; engaging low range requires stopping the vehicle completely, as with any other 4WD. Low range brings a bigger set of gears into play, meaning you can approach obstacles more slowly and carefully.
Walk the section you want to traverse, committing the terrain to memory as much as is possible. This way, there'll be no panicking surprises. Back in the vehicle, select Neutral and move the transfer lever to the 4LLc position. In a Pajero, wait for the wheels in the 4WD mode indicator to stop flashing and you're set. If they continue to flash, move the vehicle forward slightly and try again.
On rocky ground, line of approach is critical. Aim to put the wheels on the highest point of the rocks to avoid hitting underbody components. If you pick the wrong line, the worst thing that can happen to you (apart from damage to bumpers or sills) is that you high-centre the vehicle, grinding to a halt on one of the diffs, bashplates or crossmembers. If this happens, you'll probably have to use the vehicle jack to be able to physically push the vehicle off the obstacle. Try to imagine where your diffs (the lowest underbody part of the vehicle) will be as you're negotiating the rocks.
In a Pajero, the active traction control will operate automatically, so you shouldn't get any wheelspin if you apply gradual pressure to the throttle, letting the vehicle crawl over the rocky ground. But if you do, back off and try again with a slightly different line. There's no shame in this. Even the most experienced four-wheel drivers often have to have a second go!
Simpatico with the vehicle is the name of the game here. Coax rather than demand. Brake gently as you crest the rocks and ease down the other side, letting engine braking do the work where possible. And in no time, with a satisfying sense of accomplishment, you'll be at the perfect campsite or ready to tackle the next instalment of the adventure.
