HEADLIGHTS
For additional information on headlight bulb re-
placement, refer to the instructions outlined in
this section.
Replacing the halogen headlight bulb
(if so equipped)

uses a replaceable headlight (halogen) bulb.
They can be replaced from inside the engine
compartment without removing the headlight as-
sembly.
If headlight bulb replacement is required, it is
recommended that you visit a NISSAN dealer for
this service.
CAUTION
●Aiming is not necessary after replacing
the bulb. When aiming adjustment is
necessary, it is recommended that you
visit a NISSAN dealer for this service.
● Do not leave the headlight assembly
open without a bulb installed for a long
period of time. Dust, moisture, smoke,
etc. entering the headlight body may
affect bulb performance. Remove the
bulb from the headlight assembly just
before a replacement bulb is installed. ●
Only touch the base when handling the
bulb. Never touch the glass envelope.
Touching the glass could significantly
affect bulb life and/or headlight
performance.
● High pressure halogen gas is sealed
inside the halogen bulb. The bulb may
break if the glass envelope is scratched
or the bulb is dropped.
● Use the same number and wattage as
shown in the chart.
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, it is recommended that you visit a
NISSAN dealer for this service.
