HEADLIGHTS
For additional information on headlight
bulb replacement, refer to the instructions
outlined in this section.
Replacing the halogen headlight
bulb (if so equipped)
The headlight is a semi-sealed beam type
which uses a replaceable headlight (halo-
gen) bulb. They can be replaced from inside
the engine compartment without remov-
ing the headlight assembly.
If headlight bulb replacement is required, it
is recommended that you visit a NISSAN
dealer for this service.
CAUTION
∙ Aiming is not necessary af ter replac-ing 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 enve-
lope. Touching the glass could signifi-
cantly affect bulb life and/or head-
light 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.
Replacing the LED headlight bulb
(if so equipped)
If LED headlight bulb replacement is re-
quired, it is recommended that you visit a
NISSAN dealer for this service.
