Check the power steering fluid level when
the engine is stopped.
The fluid level should be between the COLD
MAX line and the COLD MIN line on the
power steering fluid reservoir at cold fluid
temperatures of 32° - 86°F (0° - 30°C) or at
the HOT MAX line on the power steering
fluid reservoir at hot fluid temperatures of
122° - 176°F (50° - 80°C).If the fluid is cold and is at or below the
COLD MIN line, add Genuine NISSAN PSF-II
or equivalent to the COLD MAX line. If the
fluid is hot and below the HOT MAX line, add
Genuine NISSAN PSF-II or equivalent to the
HOT MAX line. Remove the cap and fill
through the opening.
CAUTION
• DO NOT OVERFILL.
• Do not reuse power steering fluid.
• Recommended fluid is Genuine
NISSAN PSF-II or equivalent For additional brake fluid specification in-
formation, see “Recommended fluids/
lubricants and capacities” (P. 10-2).
WARNING
• Use only new fluid from a sealed con-
tainer. Old, inferior or contaminated
fluid may damage the brake system.
The use of improper fluids can dam-
age the brake system and affect the
vehicle's stopping ability.
• Clean the filler cap before removing.
• Brake fluid is poisonous and should
be stored carefully in marked con-
tainers out of reach of children.
CAUTION
Do not spill the fluid on any painted sur-
faces. This will damage the paint. If fluid
is spilled, immediately wash the sur-
face with water.

unexpectedly. 1. Visually inspect the belt for signs of un-
usual wear, cuts, fraying or looseness. If
the belt is in poor condition or is loose,
have it replaced or adjusted. It is recom-
mended that you visit a NISSAN dealer
for this service.
2. Have the belt checked regularly for con- dition and tension in accordance with
the maintenance schedule found in the
"Maintenance and schedules" section of
this manual.
REPLACING SPARK PLUGS
Iridium-tipped spark plugs
It is not necessary to replace iridium-
tipped
OAspark plugs as frequently as con-
ventional type spark plugs because they
last much longer. Follow the maintenance
log shown in the "Maintenance and sched-
ules" section of this manual. Do not service
iridium-tipped spark plugs by cleaning or
regapping.
• Always replace spark plugs with rec-
ommended or equivalent ones.

Brake pedal:Check the pedal for smooth
operation. If the brake pedal suddenly goes
down further than normal, the pedal feels
spongy or the vehicle seems to take longer
to stop, have your vehicle checked imme-
diately. It is recommended that you visit a
NISSAN dealer for this service. Keep the
floor mat away from the pedal.
Brakes: Check that the brakes do not pull
the vehicle to one side when applied.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjustment, it is recom-
mended that you visit a NISSAN dealer for
this service.
Seats: Check seat position controls such
as seat adjusters, seatback recliner, etc., to
ensure they operate smoothly and all
latches lock securely in every position.
Check that the head restraints/headrests
move up and down smoothly and the locks
(if so equipped) hold securely in all latched
positions.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, anchors,
adjusters and retractors) operate properly
and smoothly, and are installed securely. Check the belt webbing for cuts, fraying,
wear or damage.
Steering wheel:
Check for changes in the
steering system, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure all
warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check
that the wipers and washer operate prop-
erly and that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel).
Battery (for maintenance free batter-
ies)*: This vehicle is equipped with a sealed
maintenance free battery. It is recom-
mended that you visit a NISSAN dealer for
service.
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.
Brake fluid level*: Make sure that the fluid
level is between the MAX and MIN lines on
the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Check engine drive
belts for wear, fraying or cracking and for
proper tension. Replace any damaged
drive belts.
9-4Maintenance and schedules

Engine oil level*:Check the level af ter
parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, immedi-
ately have the exhaust system inspected. It
is recommended that you visit a NISSAN
dealer for this service. For additional infor-
mation, see “Exhaust gas (carbon monox-
ide)” (P. 5-4).
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks af ter the
vehicle has been parked for a while. Water
dripping from the air conditioner af ter use
is normal. If you should notice any leaks or if
fuel fumes are evident, check for the cause
and have it corrected immediately.
Power steering fluid level* and lines:
Check the level when the fluid is cold, with
the engine off. Check the lines for proper
attachment, leaks, cracks, etc. Radiator and hoses:
Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, defor-
mation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances, otherwise rust may form on the
floor pan, frame, fuel lines and around the
exhaust system. At the end of winter, the
underbody should be thoroughly flushed
with plain water, being careful to clean
those areas where mud and dirt may accu-
mulate. For additional information, see
“Cleaning exterior” (P. 7-2 ).
Windshield-washer fluid*: Check that
there is adequate fluid in the reservoir. The following descriptions are provided to
give you a better understanding of the
scheduled maintenance items that should
be regularly checked or replaced. The
maintenance schedule indicates at which
mileage/time intervals each item requires
service.
In addition to scheduled maintenance,
your vehicle requires that some items be
checked during normal day-to-day opera-
tion. For additional information, see “Gen-
eral maintenance” (P. 9-2).
Items marked with
“*”are recommended
by NISSAN for reliable vehicle operation.
You are not required to perform mainte-
nance on these items in order to maintain
the warranties which come with your
NISSAN. Other maintenance items and in-
tervals are required.
When applicable, additional information
can be found in the “Do-it-yourself ” section
of this manual.
