CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir
when the engine is cold. If the coolant
level is below the MIN level
B, add coolant
to the MAX level
A. If the reservoir is empty,
check the coolant level in the radiator
when the engine is cold. If there is insuffi-
cient coolant in the radiator, fill the radiator
with coolant up to the filler opening and
also add it to the reservoir up to the MAX
level
A. This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue). The life ex-
pectancy of the factory-fill coolant is
105,000 miles (168,000 km) or 7 years. Mixing
any other type of coolant or the use of
non-distilled water will reduce the life ex-
pectancy of the factory-fill coolant. For ad-
ditional information, refer to the "Mainte-
nance and schedules" section of this
manual.
If the cooling system frequently requires
coolant, it is recommended that you visit
a NISSAN dealer for this service.
For additional information on the location
of the engine coolant reservoir, refer to “En-
gine compartment check locations” in this
section.
CHANGING ENGINE COOLANT
A NISSAN dealer can change the engine
coolant. The service procedure can be
found in the NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine over-
heating.
WARNING
∙ To avoid the danger of being scalded,
never change the coolant when the
engine is hot.
∙ Never remove the radiator or engine coolant reservoir cap when the en-
gine is hot. Serious burns could be
caused by high pressure fluid escap-
ing from the radiator.
∙ Avoid direct skin contact with used coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
∙ Keep coolant out of the reach of chil- dren and pets.
Engine coolant must be disposed of prop-
erly. Check your local regulations.

sion durability, and may damage the
automatic transmission, which is not
covered by the NISSAN New Vehicle
Limited Warranty.
The specified automatic transmission fluid
is also described on caution labels located
in the engine compartment. The fluid level should be checked using the
HOT MAX range on the power steering fluid
reservoir at fluid temperatures of 122° -
176°F (50° - 80°C) or using the COLD MAX
range on the power steering fluid reservoir
at fluid temperatures of 32° - 86°F (0° - 30°C).
If the fluid is at or below the MIN line, add
Genuine NISSAN PSF-II or equivalent to HOT
MAX or COLD MAX depending on system
fluid temperature. Remove the cap and fill
through the opening.

ture ratio.
Refill the reservoir more frequently when
driving conditions require an increased
amount of windshield-washer fluid.

Antifreeze or equivalent.
CAUTION
∙Do not substitute engine antifreeze cool-
ant for windshield-washer solution. This
may result in damage to the paint.

ervoir with washer fluid concentrates
at full strength. Some methyl alcohol
based washer fluid concentrates may
permanently stain the grille if spilled
while filling the windshield-washer
reservoir.

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.

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
