Replacing components Protect valve stems with valve stem seal caps from dirt and contamination. Dirt in valve stems is a frequent source of gradual air loss.< 4. Reinitialize the Flat Tire Monitor* or reset the Tire Pressure Monitor*, refer to pages 54, 55. Do not initialize the Flat Tire Monitor when driving with a compact wheel.< 5. Replace the defective tire as soon as possible and have the new wheel/tire balanced. Do not continue driving if the V-belt is defective. The engine could be damaged due to overheating. Moreover, an increased amount of force is required for steering if there is a sharp drop in the onboard supply voltage.< Charging battery Charge the battery in the vehicle only when the engine has been switched off. For connections, refer to Jump starting on page 121. Driving with compact wheel Drive reservedly and do not exceed a speed of 50 mph/80 km/h. Mounting the compact wheel can change the driving characteristics. For example, it can reduce tracking stability during braking, extend braking distances, and alter self-steering characteristics in the limit range. With winter tires, these characteristics are more pronounced. Only one compact wheel may be mounted. You should re-equip with wheels and tires of the original size as soon as possible.< Disposal Have old batteries disposed of following replacement at your BMW Sports Activity Vehicle Center or bring them to a collection point. Maintain the battery in an upright position for transport and storage. Always secure the battery to prevent it from tipping over during transport.< Power failure After a temporary power supply interruption, some equipment is subject to limited use and must be reinitialized. Individual settings are also lost and must be updated again: > Panorama glass sunroof It may be only possible to raise the sunroof.
