Replacing components Replacing components Onboard toolkit Never touch the glass of new bulbs with your bare fingers, as even minute amounts 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.< A selection of replacement bulbs is available at your BMW center. Only replace bulbs when cool, as otherwise you may be burned.< The onboard toolkit is located in the luggage compartment lid. Loosen the wing nut to open. Whenever you perform any work on the electrical system, turn off the systems/ consumers involved to prevent short circuits from occurring. To avoid possible injury or equipment damage when replacing bulbs, observe any instructions provided by the bulb manufacturer.< For information on how to care for the headlamps, please follow the instructions on page 218. For bulbs for which changing is not described, and for checking and adjusting headlamp aim, please contact your BMW center.< Wiper blade replacement Light-emitting diodes LEDs 1. Fold the wiper arm out and grasp firmly. 2. Press the safety tabs together while sliding the wiper blade toward the front to disengage it. 3.

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.< Lamps and bulbs Lamps and bulbs make an essential contribution to vehicle safety. You must be duly diligent in replacing them. BMW recommends having your BMW center perform any work that you do not feel competent to perform yourself or that is not described here.
