The headlamps are a type of high voltage discharge tube. High voltage can remain in the circuit even with the head- lamp switch off and the key removed. Because of this, you should not attempt to service a headlamp bulb yourself. If a headlamp bulb fails, take your vehicle to an authorized dealer for service.

NOTE:

On vehicles equipped with High Intensity Discharge (HID) headlamps, when the headlamps are turned on, there is a blue hue to the lamps. This diminishes and becomes more white after approximately 10 seconds, as the system charges.

Halogen Headlamps — If Equipped

NOTE:

Lens fogging can occur under certain atmospheric condi- tions. This will usually clear as atmospheric conditions change to allow the condensation to change back to vapor. Turning the lamps on will usually accelerate the clearing process.

• Open the hood.
• Access the back of the headlamp.

NOTE:
