Some day-to-day and regular mainte-
nance is essential to maintain your vehi-
cle’s good mechanical condition, as well as
its emissions 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 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 re-
sponsibility to perform these 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 yourself, a qualified technician or, if you
prefer, a NISSAN dealer.
SCHEDULED MAINTENANCE
The maintenance items listed in this sec-
tion 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 recom-
mended that 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 techni-
cal bulletins, service tips and training pro-
grams. They are fully qualified to work on
NISSAN vehiclesbeforework begins.
If your vehicle is involved in a collision, it is
recommended that you ask your NISSAN
dealer where the nearest NISSAN Certified
Collision Center is located, or go to http://
collision.nissanusa.com.
You can be confident that a NISSAN deal-
er's service department can perform the
service needed to meet the maintenance
requirements on your vehicle. During the normal day-to-day operation of
the vehicle, general maintenance should
be performed regularly as prescribed in
this section. If you detect any unusual
sounds, vibrations or smells, be sure to
check for the cause or have it checked
promptly. In addition, it is recommended
that you visit a NISSAN dealer if you think
that repairs are required.
When performing any checks or mainte-
nance work, closely observe the “Mainte-
nance precautions” in the “Do-it-yourself ”
section of this manual.

9-2Maintenance and schedules

secondary latch keeps the hood from
opening when the primary latch is re-
leased.
When driving in areas using road salt or
other corrosive materials, check lubrica-
tion frequently.

specified. Check carefully for damage, cuts
or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the
TPMS transmitter grommet seal, valve core
and cap when the tires are replaced due to
wear or age. Wheel alignment and balance:
If the ve-
hicle should pull to either side while driving
on a straight and level road, or if you detect
uneven or abnormal tire wear, there may
be a need for wheel alignment. If the steer-
ing wheel or seat vibrates at normal high-
way speeds, wheel balancing may be
needed.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.
Windshield: Clean the windshield on a
regular basis. Check the windshield at least
every six months for cracks or other dam-
age. Have a damaged windshield repaired
by a qualified repair facility. It is recom-
mended that you have a damaged wind-
shield repaired by a NISSAN dealer, or a
NISSAN Certified Collision Center. To locate
a collision center in your area, refer to
http://collision.nissanusa.com.

sealed maintenance free battery. It is rec-
ommended 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 run-
ning (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 (if so equipped) fluid
level*:
Make sure that the brake and clutch
fluid levels are between the MIN and MAX
lines on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belt*: Make sure the drive belt
is not frayed, worn, cracked or oily.
Engine oil level*: Check the level af ter
parking the vehicle on a level surface with
the engine off. 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, refer to “Exhaust gas (carbon mon-
oxide)” in the “Starting and driving” section
of this manual.
9-4Maintenance and schedules

•Overloading not only can
shorten the life of your vehicle
and the tire, but can also cause
unsafe vehicle handling and
longer braking distances. This
may cause a premature tire
failure which could result in a
serious accident and personal
injury. Failures caused by over-
loading are not covered by the
vehicle’s warranty.
MEASUREMENT OF WEIGHTS
Secure loose items to prevent
weight shif ts that could affect the
balance of your vehicle. When the ve-
hicle is loaded, drive to a scale and
weigh the front and the rear wheels
separately to determine axle loads.
Individual axle loads should not ex-
ceed either of the gross axle weight
ratings (GAWR). The total of the axle
loads should not exceed the gross
vehicle weight rating (GVWR). These
ratings are given on the vehicle cer- tification label. If weight ratings are
exceeded, move or remove items to
bring all weights below the ratings.
Do not tow a trailer with your vehicle.
FLAT TOWING
Towing your vehicle with all four wheels on
the ground is sometimes called flat towing.
This method is sometimes used when
towing a vehicle behind a recreational ve-
hicle, such as a motor home.

and Canadian Provinces, your vehicle may
be required to be in what is called the
“ready condition” for an Inspection/
Maintenance (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 ve-
hicle.
If a powertrain system component is re-
paired or the battery is disconnected, the
vehicle may be reset to a “not ready ” condi-
tion. Before taking the I/M test, check the
vehicle's inspection/maintenance 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 seconds , the I/M test
condition is “not ready”. If the MIL does not
blink af ter 20 seconds, the I/M test condi-
tion is “ready ”. It is recommended that you
visit a NISSAN dealer to set the “ready con-
dition” or to prepare the vehicle for testing.
