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 may reduce the life ex-
pectancy of the factory-fill coolant. For ad-
ditional information, refer to “Maintenance
and schedules” section of this manual.
If the cooling system frequently requires
coolant, have it checked. It is recom-
mended 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.VK56VD engine (non-XD model)

∙ If the battery is labeled "do not open" itis maintenance free and battery fluid
should not be checked. It is recom-
mended that you visit a NISSAN dealer
or a qualified specialist workshop to
confirm the battery’s performance.
∙ Keep the battery surface clean and dry. Clean the battery with a solution of bak-
ing soda and water.
∙ Make certain the terminal connections are clean and securely tightened.
∙ Push the ignition switch to the OFF po- sition and wait 2 minutes before dis-
connecting the battery.
∙ If the vehicle is not to be used for 30 days or longer, disconnect the nega-
tive (-) battery terminal cable to prevent
discharge.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as: 1. Installation or extended use of elec-
tronic accessories that consume bat- tery power when the engine is not
running (Phone chargers, GPS, DVD
players, etc.).
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
WARNING
∙ Do not expose the battery to flames, an electrical spark or a cigarette. Hy-
drogen gas generated by the battery
is explosive. Explosive gases can
cause blindness or injury. Do not allow
battery fluid to contact your skin,
eyes, fabrics or painted surfaces. Sul-
furic acid can cause blindness or in-
jury. Af ter touching a battery or bat-
tery cap, do not touch or rub your
eyes. Thoroughly wash your hands. If
the acid contacts your eyes, skin or
clothing, immediately flush with wa-
ter for at least 15 minutes and seek
medical attention. ∙ Do not operate the vehicle if the fluid
in the battery is low. Low battery fluid
can cause a higher load on the battery
which can generate heat, reduce bat-
tery life, and in some cases lead to an
explosion.
∙ When working on or near a battery, always wear suitable eye protection
and remove all jewelry.
∙ Battery posts, terminals and related accessories contain lead and lead
compounds. Wash hands af ter
handling.
∙ This vehicle uses a special battery. If the 12-volt battery needs to be re-
placed, use a 12-volt battery of the
same design.
∙ Keep battery out of the reach of children.
∙ Do not tip the battery. Keep the vent caps tight and the battery level.

1. Remove the vent caps with a screw-driver as shown. Use a cloth to protect
the battery case.
2. Check the fluid level in each cell. If it isnecessary to add fluid, add only dis-
tilled water to bring the level up to the
bottom of the filler opening. Do not
overfill. Reinstall the vent caps. Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.
JUMP STARTING
If jump starting is necessary, refer to “Jump
starting” in the “In case of emergency” sec-
tion of this manual. If the engine does not
start by jump starting, the battery may
have to be replaced. It is recommended
