| Safety precautions when handling gas discharge bulbs |
| Never renew bulbs if you are not familiar with the necessary procedure, safety precautions and tools required. |
WARNING | High voltage! Danger to life! |
| t
| Always disconnect the battery earth cable before working on parts of the gas discharge headlights marked with yellow high-voltage warning symbols. |
| t
| Then switch dipped beam on and off again to dissipate any remaining voltage. |
| t
| Switch off ignition and all electrical equipment and remove ignition key. |
| t
| Never operate the gas discharge bulb control unit without a gas discharge bulb. |
| t
| The gas discharge bulb may only be operated in the headlight housing because of the high voltages (above 28,000 V when the gas discharge bulb is ignited). |
|
WARNING | Risk of injury from burns, UV radiation, dazzling and explosion. |
| t
| The gas discharge bulb may only be operated in the headlight housing because of the high temperatures, the absorption of UV radiation and to avoid dazzling. |
| t
| Never look into the light beam as this could disturb the eye sight for an extended period of time. |
| t
| Gas discharge bulbs are pressurised and can burst when they are renewed. |
| t
| Always wear safety goggles and gloves when removing and installing gas discharge bulbs. |
|
WARNING | Observe environmental requirements. |
| t
| Gas discharge bulbs are hazardous waste. They contain metallic mercury (Hg) and traces of thallium. |
| t
| Never break off gas discharge bulbs and do not touch broken glass part of bulb. |
| t
| Observe disposal regulations. Gas discharge bulbs should only be disposed of in the appropriate containers at an official collection point. |
|
Caution | t
| Do not touch the glass part of the gas discharge bulb with bare hands. The remaining fingerprint would be evaporated by the heat of the bulb when it is switched on, become deposited on the reflector and thus impair the brightness of the headlight. Wear clean fabric gloves when fitting the gas discharge bulb. |
| t
| Only replace defective gas discharge bulbs with gas discharge bulbs of the same type. The type can be found on the base of the bulb or on the glass part of the bulb. |
| t
| When installing, make sure connectors engage properly and are securely attached. |
