The headlight is a semi-sealed beam type
which uses a replaceable headlight (halo-
gen) bulb. A bulb can be replaced from in-
side the engine compartment without re-
moving the headlight assembly.
CAUTION
∙ High pressure halogen gas is sealedinside the halogen bulb. The bulb may
break if the glass envelope is
scratched or the bulb is dropped.
∙ When handling the bulb, do not touch the glass envelope.
∙ DO NOT TOUCH THE BULB WITH BARE HANDS.
∙ Use the same number and wattage as shown in the chart.
∙ Do not leave the bulb out of the head- light reflector for a long period of time
as dust, moisture and smoke may en-
ter the headlight body and affect the
performance of the headlight. ∙ 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.
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 servicing.

∙ The original tires have built-intread wear indicators. When the
wear indicators are visible, the
tire(s) should be replaced.
∙ Tires degrade with age and use. Have tires, including the spare,
over 6 years old checked by a
qualified technician because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.
∙ Improper service of the spare tire may result in serious per-
sonal injury. If it is necessary to
repair the spare tire, it is recom-
mended that you visit a NISSAN
dealer for this service.
∙ For additional information re- garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.
Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carry- ing capacity as originally equipped. For ad-
ditional information, refer to “Wheels and
tires” in the “Technical and consumer infor-
mation” section of this manual.
WARNING
∙ The use of tires other than those rec-
ommended or the mixed use of tires
of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the ride,
braking, handling, Vehicle Dynamic
Control (VDC) system, 4WD, ground
clearance, body-to-tire clearance, tire
chain clearance, speedometer cali-
bration, headlight aim and bumper
height. Some of these effects may
lead to accidents and could result in
serious personal injury.
∙ If your vehicle was originally equipped with four tires that were the
same size and you are only replacing
two of the four tires, install the new
tires on the rear axle. Placing new tires
on the front axle may cause loss of
vehicle control in some driving condi-
tions and cause an accident and per-
sonal injury. ∙ If the wheels are changed for any rea-
son, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear, de-
grade vehicle handling characteris-
tics, affect the VDC system and/or in-
terference with the brake discs. Such
interference can lead to decreased
braking efficiency and/or early brake
pad wear. For additional information
on wheel off-set dimensions, refer to
“Wheels and tires” in the “Technical
and consumer information” section of
this manual.
∙ When replacing a wheel without the TPMS such as the spare tire, TPMS will
not function and the low tire pressure
warning light will flash for approxi-
mately 1 minute. The light will remain
on af ter 1 minute. Have your tires re-
placed and/or TPMS system reset as
soon as possible. It is recommended
that you visit a NISSAN dealer for this
service.
∙ Replacing tires with those not origi- nally specified by NISSAN could affect
the proper operation of the TPMS.
