3. Check and correct the tire inflation pressure at the earliest opportunity. Protect valve stems with valve screw caps against dirt and contamination. Dirt in valve stems is a frequent source of gradual air loss.< 4. Initialize the Flat Tire Monitor, refer to page 92, or reset the Tire Pressure Monitor, refer to page 94. 5. Replace the damaged tire as soon as possible and have the new wheel/tire balanced. 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 restrain the battery to prevent it from tipping over during transport.< Power failure After a temporary power loss, the functioning of some equipment may be limited and require reinitialization. Individual settings are also lost and must be updated: > Seat, mirror and steering wheel memory The positions must be stored again, refer to page 44. > Time and Date The values must be updated, refer to pages 81, 82. > Radio Stations must be stored again if necessary, refer to page 168. > Navigation system Wait until the system starts, refer to page 159. Drive reservedly and do not exceed a speed of 50 mph/80 km/h. The driving characteristics change, for example reduced track stability on braking, extended braking distance, and altered self-steering characteristics in the limit range. In conjunction with winter tires, these characteristics are more pronounced. Only one compact wheel may be mounted. Restore the wheels and tires to their original size as quickly as possible. Failure to do so is a safety risk.< Vehicle battery Battery care The battery is 100% maintenance-free, i.e., the electrolyte will last for the life of the battery when the vehicle is operated in a temperate climate. Your BMW Sports Activity Vehicle Center will be glad to advise in all matters concerning the battery. Fuses Never attempt to repair a blown fuse and do not replace a defective fuse with a substitute of another color or amperage rating, as this could lead to a circuit overload, ultimately resulting in a fire in the vehicle.< Spare fuses, a pair of plastic tweezers and information on the fuse assignment are located near the fuses in the cargo bay. Charging battery Only charge the battery in the vehicle via the terminals in the engine compartment with the engine switched off.
