Headlamp: Service Precautions

HID Headlamps

CAUTION:
- HIGH VOLTAGE.
- Always disconnect negative (-) battery terminal prior to servicing any parts of the HID lamp system marked with the yellow "HIGH VOLTAGE." symbol.
- After disconnecting battery, briefly turn headlamps on and off order to discharge any residual voltage.
- The physical and mechanical properties of HID bulbs are very sensitive. Internal pressure of HID glass bulb may exceed 100 bar (in operation). Bulb temperature may exceed 700 degrees Celsius.
- The control modules for HID lamps must never be operated (headlamps turned on) without an HID lamp.
- HID bulbs must only be operated (headlamps turned on) when installed in the headlamp housing.
- Always wear safety glasses and gloves when removing and installing HID bulb.
- Never look directly at an operating HID bulb. The UV emissions of an HID bulb are approximately 2.5 times that of a comparable halogen bulb.
