CAUTION!
Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If the
bulb comes in contact with an oily surface, clean the
bulb with rubbing alcohol.
Low Beam Headlamp, High Beam Headlamp, and
Park/Turn Lamp – 300C
High Intensity Discharge Headlamps (HID) — If
Equipped
The headlamps are a type of high voltage discharge tube.
High voltage can remain in the circuit even with the
headlamp 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.
WARNING!
A transient high tension occurs at the bulb sockets of
HID headlamps when the headlamp switch is turned
ON. It may cause serious electrical shock or electro-
cution if not serviced properly. See your authorized
dealer for service.
NOTE: On vehicles equipped with HID headlamps,
when the headlamps are turned on, there is a blue hue to
the lights. This diminishes and becomes more white after
approximately 10 seconds, as the system charges.
Backup Lamp, Side Marker Lamp, and Tail/Stop
Turn Lamp — 300 Models
