HID Bulb

• Function of Left High Intensity Gas Discharge (HID) Lamp (L13) and Right High Intensity Gas Discharge (HID) Lamp (L14) can be checked using Vehicle Electrical System Control Module (J519) Output Diagnostic Test Mode (DTM). Refer to => [ Vehicle Electrical System Control Module Output Diagnostic Test Mode ] Programming and Relearning.

• Illustrations depict replacement of gas-discharge headlamp at right headlamp.

• Replacement of Left High Intensity Gas Discharge (HID) Lamp and Right High Intensity Gas Discharge (HID) Lamp is identical.

Removing:

CAUTION!
• There are pressures from 7 bar (cold) to 100 bar (hot) in the glass portion of the HID bulb. The hot glass of the bulb can reach temperatures of up to 700 degrees Celsius.

• The glass can explode and there is a danger of burning.

• When removing and installing HID bulbs, always wear safety glasses and gloves.

- Switch ignition and all electrical consumers off and disengage the key or ignition switch in position 0 (ignition off).

Installing:

Install in reverse order of removal, noting the following:

• Do not touch the glass of the HID bulb when installing. Your fingers will leave traces of grease on the glass which will evaporate and cloud the glass when the bulb is switched on.

• Do not subject the HID bulb glass to any mechanical stress. Glass cone is extremely sensitive and is also under high pressure.

• Avoid looking directly into the light beam, since the UV-rays given off by the gas-discharge lamp are approximately 2.5 times stronger than those of a halogen bulb.

• Make sure seal has proper seating when installing bracket with headlamp power output stage. It is destroyed by entry of water into headlamp.

• If a headlamp with automatic vertical headlamp aim control is removed, basic setting of headlamps must always be performed after installation.

- Insert new HID lamp so that retaining tabs lie in cut-outs in reflector.

- Check headlamp for function.

- Check headlamp adjustment and adjust headlamp if necessary.
