Removing the resonator
Remove the resonator*Aif necessary. Pull the
resonator upward to remove it. Install the
resonator securely after any inspection or
maintenance work is performed. The engine cooling system is filled at the factory
with a pre-diluted mixture of 50% Genuine
NISSAN Long Life Antifreeze/Coolant (blue) and
50% water to provide year-round anti-freeze
and coolant protection. The antifreeze solution
contains rust and corrosion inhibitors. Additional
engine cooling system additives are not neces-
sary.
WARNING
.
Never remove the radiator or cool-
ant reservoir cap when the engine is
hot. Wait until the engine and
radiator cool down. Serious burns
could be caused by high pressure
fluid escaping from the radiator.
See precautions in “If your vehicle
overheats” (P.6-12) of this manual.
. The radiator is equipped with a
pressure type radiator cap. To pre-
vent engine damage, use only a
genuine NISSAN radiator cap.
CAUTION
.Never use any cooling system ad-
ditives such as radiator sealer. Ad- ditives may clog the cooling system
and cause damage to the engine,
transmission and/or cooling sys-
tem.
. When adding or replacing coolant,
be sure to use only Genuine
NISSAN Long Life Antifreeze/Cool-
ant (blue) or equivalent. Genuine
NISSAN Long Life Antifreeze/Cool-
ant (blue) is pre-diluted to provide
antifreeze protection to −348 F
(−378C) . If additional freeze protec-
tion is needed due to weather where
you operate your vehicle, add Gen-
uine NISSAN Long Life Antifreeze/
Coolant (blue) concentrate follow-
ing the directions on the container.
If an equivalent coolant other than
Genuine NISSAN Long Life Anti-
freeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s
instructions to maintain minimum
antifreeze protection to −348 F
(−378C) . The use of other types of
coolant solutions other than Genu-
ine NISSAN Long Life Antifreeze/
Coolant (blue) or equivalent may
damage the engine cooling system.

.The life expectancy of the factory-fill
coolant is 105,000 miles (168,000
km) or 7 years. Mixing any other
type of coolant other than Genuine
NISSAN Long Life Antifreeze/Cool-
ant (blue) , including Genuine
NISSAN Long Life Antifreeze/Cool-
ant (green) , or the use of non-
distilled water will reduce the life
expectancy of the factory-fill cool-
ant. Refer to the NISSAN Service
and Maintenance Guide for more
details.

CHECKING ENGINE COOLANT LEVEL
Check the coolant level in the reservoir when
the engine is cold. If the coolant level is below
the MIN level
*2, open the reservoir cap and
add coolant up to the MAX level
*1. If the
reservoir is empty, check the coolant level in the
radiator when the engine is cold. If there is
insufficient 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
*1.
Tighten the cap securely after adding engine
coolant.
If the cooling system frequently requires
coolant, have it checked by a NISSAN
dealer.
CHANGING ENGINE COOLANT
Major cooling system repairs should be per-
formed by a NISSAN dealer. The service
procedures can be found in the appropriate
NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
. To avoid the danger of being
scalded, never change the coolant
when the engine is hot.
. Never remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping 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 reach of chil-
dren and pets.
Engine coolant must be disposed of properly.
Check your local regulations.

6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the break-
in period, depending on the severity of
operating conditions.
CAUTION
Oil level should be checked regularly.
Operating the engine with an insuffi-
cient amount of oil can damage the
engine, and such damage is not cov-
ered by the warranty.
CHANGING ENGINE OIL AND FILTER
Change the engine oil and filter according to the
maintenance log shown in the NISSAN Service
and Maintenance Guide.

conditions require an increased amount of
window washer fluid.
Recommended fluid: Genuine NISSAN Wind-
shield Washer Concentrate Cleaner & Anti-
freeze or equivalent
CAUTION
.Do not substitute engine anti-freeze
coolant for window washer solution.
This may result in damage to the
paint.
. Do not fill the window washer
reservoir tank with washer fluid
concentrates at full strength. Some
methyl alcohol based washer fluid
concentrates may permanently stain
the grille if spilled while filling the
window washer reservoir tank.
. Pre-mix washer fluid concentrates
with water to the manufacturer’s
recommended levels before pouring
the fluid into the window washer
reservoir tank. Do not use the
window washer reservoir tank to
mix the washer fluid concentrate
and water. .
Keep the battery surface clean and dry.
Clean the battery with a solution of baking
soda and water.
. Make certain the terminal connections are
clean and securely tightened.
. If the vehicle is not to be used for 30 days or
longer, disconnect the negative 7battery
terminal cable to prevent discharging it.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electro-
nic accessories that consume battery
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
or electrical sparks. Hydrogen gas
generated by the battery is explo-
sive. Do not allow battery fluid to contact your skin, eyes, fabrics or
painted surfaces. After touching a

your hands. If the acid contacts your
eyes, skin or clothing, immediately
flush with water 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 battery 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 after
