HEADLIGHTS
Replacing
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.
Xenon headlight bulb (if so equipped) :
If replacement is required, see an INFINITI re-
tailer.
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.Halogen headlight bulb (if so equipped) :
The headlight is a semi-sealed beam type which
uses a replaceable headlight (halogen) bulb. If
replacement is required, see an INFINITI retailer
for servicing.
CAUTION
●
High pressure halogen gas is sealed inside
the bulb. The bulb may break if the glass
envelope is scratched or the bulb is dropped.
● Only touch the plastic base when handling
the bulb. Never touch the glass envelope.
Touching the glass could significantly affect
bulb life and/or headlight performance.
● Do not leave the bulb out of the headlight
reflector for a long period of time as dust,
moisture, and smoke may enter the head-
light body and affect the performance of the
headlight.
● Aiming is not necessary after replacing the
bulb. When aiming adjustment is necessary,
contact an INFINITI retailer.
