●Use the correct jack-up points. Never
use any other part of the vehicle for jack
support.
● Never jack up the vehicle more than
necessary.
● Never use blocks on or under the jack.
● Do not start or run the engine while
vehicle is on the jack. It may cause the
vehicle to move. This is especially true
for vehicles with limited slip
differentials.
● Do not allow passengers to stay in the
vehicle while it is on the jack.
● Never run the engine with a wheel(s) off
the ground. It may cause the vehicle to
move. Always refer to the proper illustrations for the
correct placement and jack-up points for your
specific vehicle model and jack type.
Carefully read the caution label attached to
the jack body and the following instruc-
tions.
1. Loosen each wheel nut one or two turns by turning counterclockwise with the wheel nut
wrench. Do not remove the wheel nuts
until the tire is off the ground. 2. Place the jack directly under the jack-up
point as illustrated so the top of the jack
contacts the vehicle at the jack-up point.

not start right away, place the ignition
switch in the OFF position and wait 3 to
4 seconds before trying again.
8. After starting the engine, carefully discon- nect the negative cable and then the positive
cable.
CAUTION
●Do not push start this vehicle. The
three-way catalyst may be damaged.
● Continuously Variable Transmission
(CVT) models and Manual Transmission
(MT) cannot be push-started or tow-
started. Attempting to do so may cause
transmission damage
● For manual transmission (MT) models,
never try to start the vehicle by towing it.
When the engine starts, the forward
surge could cause the vehicle to collide
with the tow vehicle. If your vehicle is overheating (indicated by an
extremely high temperature gauge reading) , or if
you feel a lack of engine power, detect abnormal
noise, etc., take the following steps.
WARNING
●
Do not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
● To avoid the danger of being scalded,
never remove the radiator cap while the
engine is still hot. When the radiator
cap is removed, pressurized hot water
will spurt out, possibly causing serious
injury.

should not leak water. If coolant is leaking,
the water pump belt is missing or loose, or
the cooling fan does not run, stop the en-
gine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling fan
can start at any time. 6. After the engine cools down, check the cool-
ant level in the engine coolant reservoir with
the engine running. Add coolant to the en-
gine coolant reservoir if necessary. Have
your vehicle repaired at a NISSAN dealer. When towing your vehicle, all State (Provincial in
Canada) and local regulations for towing must be
followed. Incorrect towing equipment could dam-
age your vehicle. Towing instructions are avail-
able from a NISSAN dealer. Local service opera-
tors are generally familiar with the applicable laws
and procedures for towing. To assure proper
towing and to prevent accidental damage to your
vehicle, NISSAN recommends having a service
operator tow your vehicle. It is advisable to have
the service operator carefully read the following
precautions:
WARNING
●
Never ride in a vehicle that is being
towed.
● Never get under your vehicle after it has
been lifted by a tow truck.
CAUTION
● When towing, make sure that the trans-
mission, axles, steering system and

Your NISSAN has been designed to have mini-
mum maintenance requirements with long ser-
vice intervals to save you both time and money;
however, some day-to-day and regular mainte-
nance is essential to maintain your NISSAN’s
good mechanical condition as well as its emis-
sions and engine performance.
It is the owner’s responsibility to make sure that
the scheduled maintenance, as well as general
maintenance, is performed.
As the vehicle owner, you are the only one who
can ensure that your vehicle receives proper
maintenance. You are a vital link in the mainte-
nance chain.
Scheduled maintenance
For your convenience, both required and optional
scheduled maintenance items are described and
listed in your “NISSAN Service and Maintenance
Guide”. You must refer to that guide to ensure
that necessary maintenance is performed on your
NISSAN at regular intervals.
General maintenance
General maintenance includes those items which
should be checked during normal day-to-day op-
eration. They are essential for proper vehicle op-
eration. It is your responsibility to perform these
maintenance procedures 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 you,
a qualified technician or, if you prefer, a NISSAN
dealer.
Where to go for service
If maintenance service is required or your vehicle
appears to malfunction, have the systems
checked and corrected by a NISSAN dealer.
NISSAN technicians are well-trained specialists
who are kept up-to-date with the latest service
information through technical bulletins, service
tips and in-dealership training programs. They
are completely qualified to work on NISSAN ve-
hicles
before they work on your vehicle rather
than after they have worked on it.
You can be confident that a NISSAN dealer’s
service department performs the best job to meet
the maintenance requirements on your vehicle —
in a reliable and economical way. During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smells, be sure to check for the cause or have a
NISSAN dealer do it promptly. In addition, you
should notify a NISSAN dealer if you think that
repairs are required.
When performing any checks or maintenance
work, closely observe the “Maintenance precau-
tions” in this section.
EXPLANATION OF GENERAL
MAINTENANCE ITEMS
Additional information on the following
items with“*”isfound in this section.
Outside the vehicle
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Doors and engine hood
Check that the doors
and engine hood operate properly. Also ensure
that all latches lock securely. Lubricate hinges,
latches, latch pins, rollers and links as necessary.
Make sure that the secondary latch keeps the
hood from opening when the primary latch is
released.
MAINTENANCE REQUIREMENTS GENERAL MAINTENANCE
8-2Maintenance and do-it-yourself

SeatsCheck 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 web-
bing for cuts, fraying, wear or damage.
Steering wheel Check for changes in the steer-
ing system, such as excessive freeplay, hard
steering or strange noises.
Warning lights and chimes Make sure all
warning lights and chimes are operating properly.
Windshield wiper and washer* Check that
the wipers and washer operate properly and that
the wipers do not streak.
Windshield defroster Check that the air
comes out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner (if so equipped) .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. Ve-
hicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
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 electronic accessories that consume battery power
when the engine is not running (Phone char-
gers, 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 (if so equipped) lev-
els* Make sure that the brake and clutch fluid
level is between the MIN and MAX lines on the
reservoir. Engine coolant level*
Check the coolant level
when the engine is cold.
Engine drive belts* Make sure the drive belts
are not frayed, worn, cracked or oily.
Engine oil level* Check the level after parking
the vehicle on a level surface with the engine off.
Wait more than 10 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, immediately have the exhaust
system inspected by a NISSAN dealer. For addi-
tional information, refer to the “Exhaust gas (car-
bon monoxide)” in the “Starting and driving” sec-
tion of this manual.
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 (if so equipped) after use is nor-
mal. If you should notice any leaks or if gasoline
fumes are evident, check for the cause and have
it corrected immediately.
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.
8-4Maintenance and do-it-yourself

UnderbodyThe underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances from the
underbody, otherwise rust may form on the floor
pan, frame, fuel lines and exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, in those areas
where mud and dirt may have accumulated. For
additional information, refer to “Underbody” in the
“Appearance and care” section of this manual.
Windshield-washer fluid* Check that there is
adequate fluid in the reservoir. When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING
●
Park the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. For manual transmission
models, move the shift lever to N (Neu-
tral) . For CVT models, move the shift
lever to P (Park) .
● Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
● If you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans, belts
and any other moving parts.
● It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
● Always wear eye protection whenever
you work on your vehicle. ●
If you must run the engine in an en-
closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
● Never get under the vehicle while it is
supported only by a jack. If it is neces-
sary to work under the vehicle, support
it with safety stands.
● Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
● On gasoline engine models, the fuel
filter or fuel lines should be serviced by
a NISSAN dealer because the fuel lines
are under high pressure even when the
engine is off.
● Your vehicle is equipped with an auto-
matic engine cooling fan. It may come
on at any time without warning, even if
the ignition key is in the OFF position
and the engine is not running. To avoid
injury, always disconnect the negative
battery cable before working near the
fan.
