2. Add distilled water up to the UPPERLEVELline.
If the side of the battery is not clear,
check the distilled water level by
looking directly above the cell; the
condition
indicates OK and the
conditionsneeds more to be added.
3. Tighten cell plugs
.
Vehicles operated in high temperatures
or under severe conditions require fre-
quent checks of the battery fluid level.
JUMP STARTING
If jump starting is necessary, see “Jump
starting” (P.6-15). If the engine does not
start by jump starting, the battery may
have to be replaced. It is recommended
you visit a NISSAN dealer for this service.CAUTION
. Do not ground accessories di-
rectly to the battery terminal.
Doing so will bypass the variable
voltage control system and the
vehicle battery may not charge
completely.
. Use electrical accessories with
the engine running to avoid dis-
charging the vehicle battery.
The variable voltage control system mea-
sures the amount of electrical discharge
from the battery and controls voltage
generated by the generator.

9-2Maintenance and schedules
Some day-to-day and regular mainte-
nance is essential to maintain your vehi-
cle in good mechanical condition, as well
as its emission and engine performance.
It is the owner’s responsibility to make
sure that the scheduled maintenance, as
well as general maintenance, is per-
formed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
the proper maintenance. You are a vital
link in the maintenance chain.
GENERAL MAINTENANCE
General maintenance includes those
items which should be checked during
normal day-to-day operation. They are
essential for proper vehicle operation. It is
your responsibility to perform these pro-
cedures regularly as prescribed.
Performing general maintenance checks
requires minimal mechanical skill and
only a few general automotive tools.
These checks or inspections can be done
by yourself, a qualified technician or, if you
prefer, a NISSAN dealer.
SCHEDULED MAINTENANCE
The maintenance items listed in this
section are required to be serviced at
regular intervals. However, under severe
driving conditions, additional or more
frequent maintenance will be required.
WHERE TO GO FOR SERVICE
If maintenance service is required or your
vehicle appears to malfunction, have the
systems checked and serviced. It is re-
commended you visit a NISSAN dealer for
this service.
NISSAN technicians are well-trained spe-
cialists and are kept up to date with the
latest service information through tech-
nical bulletins, service tips and training
programs. They are completely qualified
to work on NISSAN vehiclesbeforework
begins.
You can be confident that a NISSAN
dealer’s service department can perform
the service needed to meet the mainte-
nance requirements on your vehicle. During the normal day-to-day operation
of the vehicle, general maintenance
should be performed regularly as pre-
scribed in this section. If you detect any
unusual sounds, vibrations or smells, be
sure to check for the cause, or it is
recommended to have a NISSAN dealer
do it promptly. In addition, it is recom-
mended you visit a NISSAN dealer if you
think that repairs are required.
When performing any checks or mainte-
nance work, closely observe “Mainte-
nance precautions” (P.8-2) of this manual.
EXPLANATION OF GENERAL MAIN-
TENANCE ITEMS
Additional information on the following
items with “*” is found in the “8. Do-it-
yourself” section of this manual.
Outside the vehicle
The maintenance items listed here should
be performed from time to time, unless
otherwise specified.
Doors and engine hood:
Check that all
doors and the engine hood, operate
properly. Also ensure that all latches lock
securely. Lubricate hinges, latches, latch
pins, rollers and links if necessary. Make
sure that the secondary latch keeps the
hood from opening when the primary
latch is released.
MAINTENANCE REQUIREMENT GENERAL MAINTENANCE

9-4Maintenance and schedules
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 conditions, such as excessive
free play, hard steering or strange noises.
Warning lights and chimes: Make sure
that all warning lights and chimes are
operating properly.
Windshield defroster: Check that the air
comes out of the defroster outlets prop-
erly and in sufficient quantity when oper-
ating the heater or air conditioner.
Windshield wiper and washer*: Check
that the wipers and washer operate
properly 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*: Check the fluid level in each cell.
It should be between the MAX and MIN
lines. Vehicles operated in high tempera-
tures or under severe condition require
frequent checks of the battery fluid level. NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start condi-
tions such as:
1.
Installation or extended use of elec-
tronic 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.
Brake and clutch fluid levels*: Make sure
that the brake and clutch fluid levels are
between the MAX and MIN lines on the
reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no
belt is frayed, worn, cracked or oily.
Engine oil level*: Check the level after
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, im- mediately have the exhaust system in-
spected. It is recommended you visit a
NISSAN dealer for this service. (See “Pre-
cautions when starting and driving” (P.5-
2) for exhaust gas (carbon monoxide).)
Fluid leaks:
Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use
is normal. If you should notice any leaks
or if gasoline fumes are evident, check for
the cause and have it corrected immedi-
ately.
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,
deformation, 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
substances, otherwise rust will 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 accumulate. For additional informa-
tion, 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 op-
eration. Refer to “General maintenance”
(P.9-2).
Items marked with “*” are recommended
by NISSAN for reliable vehicle operation.
You are not required to perform main-
tenance on these items in order to
maintain the warranties which come with
your vehicle. Other maintenance items
and intervals are required.
When applicable, additional information
can be found in the “8. Do-it yourself”
section of this manual.
NOTE:
NISSAN does not advocate the use of
non-OEM approved aftermarket flush-
ing systems and strongly advises
against performing these services on a
NISSAN product. Many of the aftermar-
ket flushing systems use non-OEM ap-
proved chemicals or solvents, the use of
which has not been validated by
NISSAN.For recommended fuel, lubricants,
fluids, grease, and refrigerant, refer to
“Capacities and recommended fluids/
lubricants” (P.10-2) of this manual.
EMISSION CONTROL SYSTEM MAIN-
TENANCE
Drive belts*:
Check engine drive belts for wear, fraying

are a different size from the rear tires and
the direction of wheel rotation is fixed in
each tire.
Transmission fluid/oil, differential oil:
Visually inspect for signs of leakage at
specified intervals.
To help ensure smooth, safe and eco-
nomical driving, NISSAN provides two
maintenance schedules that may be
used, depending upon the conditions in
which you usually drive. These schedules
contain both distance and time intervals,
up to 120,000 miles (192,000 km)/144
months. For most people, the odometer
reading will indicate when service is
needed. However, if you drive very little,
your vehicle should be serviced at the
regular time intervals shown in the sche-
dule.
After 120,000 miles (192,000 km)/144
months, continue maintenance at the
same mileage/time intervals.
ADDITIONAL MAINTENANCE ITEMS
FOR SEVERE OPERATING CONDI-
TIONS
Additional maintenance items for se-
vere operating conditions;
should be
performed on vehicles that are driven
under especially demanding conditions.
Additional maintenance items should be
performed if you primarily operate your
vehicle under the following conditions:
. Repeated short trips of less than 5
miles (8 km).
. Repeated short trips of less than 10
miles (16 km) with outside tempera-
tures remaining below freezing.

vent or similar ingredients that can be
harmful to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended above
can cause persistent, heavy spark
knock. (Spark knock is a metallic rap-
ping noise.) If severe, this can lead to
engine damage. If you detect a persis-
tent heavy spark knock even when
using gasoline of the stated octane
rating, or if you hear steady spark knock
while holding a steady speed on level
roads, it is recommended you have a
NISSAN dealer correct the condition.
Failure to correct the condition is mis-
use of the vehicle, for which NISSAN is
not responsible.
Incorrect ignition timing will result in
knocking, after-run or overheating. This
in turn may cause excessive fuel con-
sumption or damage to the engine. If any
of the above symptoms are encountered,
have your vehicle checked at a NISSAN
dealer or other competent service facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is
no cause for concern, because you get
the greatest fuel benefit when there is
light spark knock for a short time underheavy engine load.

and Canadian Provinces, your vehicle may
be required to be in what is called the
“ready condition” for an Inspection/Main-
tenance (I/M) test of the emission control
system.
The vehicle is set to the “ready condition”
when it is driven through certain driving
patterns. Usually, the “ready condition”
can be obtained by ordinary usage of
the vehicle.
If a powertrain system component is
repaired or the battery is disconnected,
the vehicle may be reset to a “not ready
condition”. Before taking the I/M test,
check the vehicle’s inspection/mainte-
nance test readiness condition. Place the
ignition switch in the ON position without
starting the engine. If the Malfunction
Indicator Light (MIL) comes on steady for
20 seconds and then blinks for 10 sec-
onds, the I/M test condition is “not ready”.
If the MIL does not blink after 20 seconds,
the I/M test condition is “ready”.
It is recommended you visit a NISSAN
dealer to set the “ready condition” or to
prepare the vehicle for testing.This vehicle is equipped with an Event
Data Recorder (EDR). The main purpose of
an EDR is to record, in certain crash or
near crash-like situations, such as an air
bag deployment or hitting a road obsta-
cle, data that will assist in understanding
how a vehicle’s systems performed. The
EDR is designed to record data related to
vehicle dynamics and safety systems for a
short period of time, typically 30 seconds
or less. The EDR in this vehicle is designed
to record such data as:
.
How various systems in your vehicle
were operating;
. Whether or not the driver and passen-
ger safety belts were buckled/fas-
tened;
. How far (if at all) the driver was
depressing the accelerator and/or
brake pedal; and,
. How fast the vehicle was traveling.
. Sounds are not recorded.
These data can help provide a better
understanding of the circumstances in
which crashes and injuries occur. NOTE:
EDR data are recorded by your vehicle
only if a nontrivial crash situation occurs;
no data are recorded by the EDR under
normal driving conditions and no perso-
nal data (e.g. name, gender, age and crash
location) are recorded. However, other
parties, such as law enforcement, could
