Operation Driving instructions i Whenever driving in off-road mode, we recommend: Keeping doors, tailgate, windows and sliding/pop-up roof closed. Switching cruise control off. Avoid excessive engine speeds - drive at moderate engine speeds (max. 3000 rpm). Before driving through water, determine its depth. Do not stop vehicle while immersed in water, and do not shut off the engine. In sandy soil, drive at a steady speed as allowed by conditions. This helps overcome the vehicle rolling resistance and reduces the likelihood of the vehicle sinking into the ground. Do not initiate jumps with the vehicle. It interrupts the forward momentum of the vehicle. Always drive on slopes with the engine running and the vehicle in gear. Inspect the vehicle for possible damage after each off-road trip. Checklist before off-road driving Engine oil level Check the engine oil level ( page 229). The display ENGINE OIL LEVEL - OK must appear in the multifunction display. Only then can the vehicle obtain a trouble-free oil supply, even on steep gradients. Tires Check the tread depth and maintain specified tire pressure (see tire pressure label inside the fuel filler flap). Check tires for possible damage and remove foreign objects. Replace missing valve caps. ! Observe the following during off-road driving: Adjust vehicle speed to condition of terrain. The more uneven, rutty and steeper the terrain, the lower the speed should be. Drive through water slowly at an even speed, avoiding a bow wave. Be especially careful when driving in unknown territory. It may be necessary to get out of the vehicle and scout the path you intend to take. Watch out for obstacles, such as rocks, holes, tree stumps and ruts. 215
