Do not change wheels on uphill or downhill gradients. Contact a qualified specialist work- shop. R only position the jack at the appropriate jacking point of the vehicle.
Make sure that the jack is correctly positioned at the jack- ing point before raising the vehicle. R before raising the vehicle, secure it against rolling away by applying the parking brake and using wheel chocks. Never release the parking brake while the vehicle is raised. G WARNING If you do not position the jack correctly at the appropriate jacking point of the vehicle, the jack could tip over with the vehicle raised. There is a risk of injury. Only position the jack at the appropriate jack- ing point of the vehicle. The base of the jack must be positioned vertically, directly under the jacking point of the vehicle. R the jack must be placed on a firm, flat and non-slip surface.
