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*: Make sure the drive
belts are not frayed, worn, cracked or oily.
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

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, refer to
the “Appearance and care” section of this
manual.

9-8Maintenance and schedules

NOTE:Maintenance items with “” should be performed more frequently according to the “Maintenance under severe driving conditions”.
(1) If operating mainly in dusty conditions, more frequent maintenance may be required.
(2) Request the dealer to inspect the fluid deterioration data using a CONSULT. If the deterioration data is more than 77000, replace the AT fluid.
(3) If using under severe conditions such as towing a trailer, using a car-top carrier, or driving on rough or muddy roads, change (not just inspect) oilat every
30,000 miles (48,000 km) or 24 months. NISSAN recommends using Genuine NISSAN Matic P automatic transmission fluid. Using automatic transmission
fluid that is not equivalent to Genuine NISSAN Matic P may damage the transmission or impact transmission durability. Damage caused by the use of fluid
other than as recommended is not covered under the NISSAN New Vehicle Limited Warranty.

WARNING
• It is extremely dangerous to
ride in a cargo area inside a ve-
hicle. In a collision, people rid-
ing in these areas are more
likely to be seriously injured or
killed.
• Do not allow people to ride in
any area of your vehicle that is
not equipped with seats and
seat belts.
• Be sure everyone in your ve-
hicle is in a seat and using a
seat belt properly.TERMS
It is important to familiarize yourself
with the following terms before
loading your vehicle:
• Curb Weight (actual weight of your vehicle) - vehicle weight including:
standard and optional equipment,
fluids, emergency tools, and spare
tire assembly. This weight does
not include passengers and cargo.
• GVW (Gross Vehicle Weight) - curb weight plus the combined weight
of passengers and cargo.
• GVWR (Gross Vehicle Weight Rat- ing) - maximum total combined
weight of the unloaded vehicle,

WARNING
A vehicle equipped with Four-Wheel
Drive (4WD) should never be tested us-
ing a two wheel dynamometer (such as
the dynamometers used by some
states for emissions testing), or similar
equipment. Make sure you inform the
test facility personnel that your vehicle
is equipped with 4WD before it is placed
on a dynamometer. Using the wrong
test equipment may result in transmis-
sion damage or unexpected vehicle
movement which could result in seri-
ous vehicle 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 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 obstacle, data
that will assist in understanding how a ve-
hicle's systems performed. The EDR is de-
signed to record data related to vehicle dy-
namics and safety systems for a short
period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to re-
cord such data as:
• How various systems in your vehicle were
operating;
• Whether or not the driver and passenger 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.
