Replacing components Onboard tool kit When working on the lighting system, you should always switch off the lights affected to prevent short circuits. To avoid possible injury or equipment damage when replacing bulbs, follow any instructions provided by the bulb manufacturer.< When maintaining the headlamps, please follow the instructions in the separate Caring for your vehicle brochure. Light-emitting diodes LEDs The onboard toolkit is located in the luggage compartment lid. Loosen the wingnut to open. The adapter for the spare key can be stored beneath the open-ended wrenches. Light-emitting diodes installed behind translucent lenses serve as the light source for many of the controls and displays in your vehicle. These light-emitting diodes, which operate using a concept similar to that applied in conventional lasers, are officially designated as Class 1 lightemitting diodes. Do not remove the covers, and never stare into the unfiltered light for several hours, as irritation of the retina could result.< Windshield wiper blades To replace the blades, start by folding the wipers out and away from the windshield, refer to page 66. Xenon lamp* The service life of these bulbs is very long and the probability of a failure is very low, provided that they are not switched on and off an unusual number of times. In the unlikely event that one of these lamps should fail, you can respond by switching on your fog lamps and proceeding carefully, where allowed by law. Only have work on the xenon lighting system including bulb changes carried out by a BMW center or a repair shop that works in accordance with BMW guidelines and uses appropriately trained personnel. Due to the high voltage involved, there is a danger to life and limb when work is carried out improperly.< For checking and adjusting headlamp aim, please contact your BMW center.< Lamps and bulbs Lamps and lights contribute significantly to road safety. Therefore, comply fully with the following instructions during bulb replacement. BMW recommends that you entrust corresponding procedures to your BMW center if you are unfamiliar with them or they are not described here. Never touch the glass of new bulbs with your bare fingers, as even minute traces of contamination will burn into the bulb's surface and reduce its service life. Use a clean cloth, napkin, etc., or hold the bulb by its metal socket.< You can obtain a selection of replacement bulbs at your BMW center. 213 Online Edition for Part no. 01 41 0 013 316 - © 02/07 BMW AG Reference Mobility Communications Entertainment Navigation Driving tips Controls At a glance
