HEADLIGHTS
Replacing
Xenon headlight bulb :
WARNING
HIGH VOLTAGE
When xenon headlights are on, they produce a
high voltage. To prevent an electric shock,
never attempt to modify or disassemble. Al-
ways have your xenon headlights replaced at
an INFINITI retailer. For additional information,
see “HEADLIGHT AND TURN SIGNAL SWITCH” in
the “2. Instruments and controls” section.
Use the same number and wattage shown in the
following chart as originally installed.
If replacement is required, see an INFINITI re-
tailer.
Fog may temporarily form inside the lens of the
exterior lights in the rain or in a car wash. A
temperature difference between the inside and
the outside of the lens causes the fog. This is
not a malfunction. If large drops of water collect
inside the lens, contact an INFINITI retailer.
