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 warranty.
∙ It is normal to add some oil between oil maintenance intervals or during
the break-in period, depending on the
severity of operating conditions.
CHANGING ENGINE OIL AND OIL
FILTER
For additional information on engine oil
and oil filter change, refer to the instruc-
tions outlined in this section.
Vehicle set-up
1. Park the vehicle on a level surface and
apply the parking brake.
2. Run the engine until it reaches operat- ing temperature.
3. Turn the engine off and wait for 15 min- utes.
4. Raise and support the vehicle using a suitable floor jack and safety jack
stands. ∙ Place the safety jack stands under the
vehicle jack-up points.
∙ A suitable adapter should be attached to the jack stand saddle.

∙ If the battery is labeled “do not open” it ismaintenance free and battery fluid
should not be checked. It is recom-
mended that you visit a NISSAN dealer
or a qualified specialist workshop to
confirm the battery’s performance.
∙ Keep the battery surface clean and dry. Clean the battery with a solution of bak-
ing 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 nega-
tive (-) battery terminal cable to prevent
discharge.
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.

If any electrical equipment does not oper-
ate, check for an open fuse.
Fuses are used in the passenger and en-
gine compartment. Spare fuses are pro-
vided and can be found in the passenger
compartment fuse box.
When installing a fuse make sure the fuse is
installed in the fuse box securely.ENGINE COMPARTMENT

WARNING
A vehicle equipped with All -Wheel Drive
(AWD) should never be tested using a
two wheel dynamometer (such as the
dynamometers used by some states for
emissions testing), or similar equip-
ment. Make sure you inform the test fa-
cility personnel that your vehicle is
equipped with AWD before it is placed
on a dynamometer. Using the wrong
test equipment may result in drivetrain
damage or unexpected vehicle move-
ment which could result in serious ve-
hicle damage or personal injury.
Due to legal requirements in some states
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.
This vehicle is equipped with an EDR. The
main purpose of an EDR is to record, in
certain collision or near collision-like situa-
tions, such as an air bag deployment or
hitting a road obstacle, 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/fastened;
∙ How far (if at all) the driver was depress- ing the accelerator and/or brake pedal;
and,
∙ How fast the vehicle was traveling.
∙ Sounds are not recorded.
These data can help provide a better un-
derstanding of the circumstances in which
collisions and injuries occur. NOTE: EDR
data are recorded by your vehicle only if a
nontrivial collision situation occurs; no data
are recorded by the EDR under normal driv-
ing conditions and no personal data (e.g.
name, gender, age and collision location)
