Operation Driving instructions 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 240). 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 inflation pressure (a placard with the recommended tire inflation pressures is located on the driver's door B-pillar ( page 251)). Check tires for possible damage and remove foreign objects. Replace missing valve caps. Rims Dented or bent rims can cause tire inflation pressure loss and damage the tire beads. For this reason, check and, if necessary, change rims before driving off-road. Vehicle tool kit Check if the vehicle jack is functional. In all cases take the vehicle tool kit, a strong tow rope, a shovel and a small plank (to put under the vehicle jack on sandy soil) with you. 225
