•Do not attempt to top off the fuel
tank af ter the fuel pump nozzle
shuts off automatically. Continued
refueling may cause fuel overflow,
resulting in fuel spray and possibly a
fire.
• Use only an original equipment type
fuel-filler cap as a replacement. It has
a built-in safety valve needed for
proper operation of the fuel system
and emission control system. An in-
correct cap can result in a serious
malfunction and possible injury. It
could also cause the
Malfunc-
tion Indicator Light (MIL) to come on.
• Never pour fuel into the throttle body
to attempt to start your vehicle.
• Do not fill a portable fuel container in
the vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable
fuel containers:
– Always place the container on the
ground when filling.
– Do not use electronic devices
when filling. –
Keep the pump nozzle in contact
with the container while you are
filling it.
– Use only approved portable fuel
containers for flammable liquid.
CAUTION
• Do not use a fuel containing more
than 15% ethanol in your vehicle. For
additional information, refer to “Fuel
recommendation” in the “Technical
and consumer information” section
of this manual.
• The LOOSE FUEL CAP warning will ap-
pear if the fuel-filler cap is not prop-
erly tightened. It may take a few driv-
ing trips for the message to be
displayed. Failure to tighten the fuel-
filler cap properly af ter the LOOSE
FUEL CAP warning appears may
cause the
Malfunction Indicator
Light (MIL) to illuminate. •
Failure to tighten the fuel-filler cap
properly may cause the
Mal-
function Indicator Light (MIL) to illu-
minate. If the
light illuminates
because the fuel-filler cap is loose or
missing, tighten or install the cap and
continue to drive the vehicle. The
light should turn off af ter a few
driving trips. If thelight does not
turn off af ter a few driving trips, have
your vehicle inspected. It is recom-
mended that you visit a NISSAN
dealer for this service.
• For additional information, refer to
“Malfunction Indicator Light (MIL)” in
the “Instruments and controls” sec-
tion in this manual.
• If fuel is spilled on the vehicle body,
flush it away with water to avoid
paint damage.
3-14Pre-driving checks and adjustments

WARNING
• Do not leave children or adults who
would normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
• Properly secure all cargo with ropes
or straps to help prevent it from slid-
ing or shif ting. Do not place cargo
higher than the seatbacks. In a sud-
den stop or collision, unsecured
cargo could cause personal injury.
EXHAUST GAS (carbon monoxide)air recirculation but-
ton to off and the fan control dial
to high to circulate the air.
• If electrical wiring or other cable con-
nections must pass to a trailer
through the seal on the lif tgate or the
body, follow the manufacturer's rec-
ommendation to prevent carbon
monoxide entry into the vehicle. •
The exhaust system and body should
be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involv- ing damage to the exhaust sys-
tem, underbody, or rear of the
vehicle.
• If a special body, camper, or other
equipment is added for recreational
or other usage, follow the manufac-
turer's recommendation to prevent
carbon monoxide entry into the ve-
hicle. Do not occupy these areas
while the engine is running even if
the vehicle is parked. Some recre-
ational vehicle appliances such as
stoves, refrigerators, heaters, etc.
may also generate carbon monoxide.
PRECAUTIONS WHEN STARTING AND
DRIVING
5-2Starting and driving

•When driving on roads covered with
snow or ice, the TEMPORARY FULL
SIZE spare tire should be used on the
front wheels and the original tire
used on the rear wheels. Use tire
chains only on the drive wheels.
• Do not use the TEMPORARY FULL SIZE
spare tire on other vehicles.
• Do not use more than one TEMPO-
RARY FULL SIZE spare tire at the same
time.
• Do not tow a trailer when the TEMPO-
RARY FULL SIZE spare tire is installed.CAUTION
• Do not use tire chains on a TEMPO-
RARY FULL SIZE spare tire. Tire chains
will not fit properly and may cause
damage to the vehicle.
• Use of the TEMPORARY FULL SIZE
spare tire on a vehicle that has tires
larger than were originally equipped
can affect the 4WD System. This may
result in a circumference difference
between tires on front and rear axles
which can cause the 4WD system to
automatically place the vehicle in
2WD and flash the 4WD light. When
the TEMPORARY FULL SIZE spare tire
is replaced with a tire that matches
all other tires on the vehicle, and all
tires are properly inflated the 4WD
system will operate normally.
8-42Do-it-yourself

To help ensure smooth, safe and economi-
cal driving, NISSAN provides two mainte-
nance schedules that may be used, de-
pending upon the conditions in which you
usually drive. These schedules contain
both distance and time intervals, up to
120,000 miles (192,000 km)/96 months. For
most people, the odometer reading will in-
dicate when service is needed. However, if
you drive very little, your vehicle should be
serviced at the regular time intervals
shown in the schedule.
Af ter 120,000 miles (192,000 km)/96
months, continue maintenance at the
same mileage/time intervals.
ADDITIONAL MAINTENANCE ITEMS
FOR SEVERE OPERATING
CONDITIONS
Additional maintenance items for severe
operating conditionsshould be per-
formed on vehicles that are driven under
especially demanding conditions. Addi-
tional maintenance items should be per-
formed 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 temperatures re-
maining below freezing.
• Operating in hot weather in stop-and-go “rush hour” traffic.
• Extensive idling and/or low speed driving for long distances, such as police, taxi or
door-to-door delivery use.
• Driving in dusty conditions.
• Driving on rough, muddy or salt spread roads.
• Towing a trailer, using a camper or using a car-top carrier.
NOTE:
For vehicles operated in Canada, both
standard and severe maintenance items
should be performed at every interval. The following tables show the standard
maintenance schedule. Depending upon
weather and atmospheric conditions,
varying road surfaces, individual driving
habits and vehicle usage, additional or
more frequent maintenance may be re-
quired.
Af ter 120,000 miles (192,000 km)/96
months, continue maintenance at the
same mileage/time intervals.
MAINTENANCE SCHEDULES
STANDARD MAINTENANCE
Maintenance and schedules9-7

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.
(4) Af ter 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace the drive belts if found damaged.
(5) First replacement interval is 105,000 miles (168,000 km) or 84 months. Af ter first replacement, replace every 75,000 miles (120,000 km) or 60 mont hs.
(6) Use only Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent with proper mixture ratio of 50% antifreeze and 50% demineralized or di stilled
water. Mixing any other type of coolant or the use of non-distilled water may reduce the life expectancy of the factory fill coolant.
(7) Periodic maintenance is not required.
(8) Periodic maintenance is not required. However, if valve noise increased, inspect valve clearance.
(9) Replace spark plug when the plug gap exceeds 0.053 in (1.35 mm) even if within specified replacement mileage.
(10) For additional information on tire rotation, refer to “General maintenance” in the section.
(11) If towing a trailer, using a car-top carrier or driving on rough or muddy roads, change (not just inspect) oil at every 20,000 miles (32,000 km) or 24 months.
* Maintenance items and intervals with “*” are recommended by NISSAN for reliable vehicle operation. The owner need not perform such maintenance in
order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and intervals are required.

Change intervals
The oil and oil filter change intervals for
your engine are based on the use of the
specified quality oils and filters. Using en-
gine oil and filters that are not of the speci-
fied quality, or exceeding recommended oil
and filter change intervals could reduce
engine life or cause severe damage to the
engine. Damage to the engine caused by
improper maintenance or use of incorrect
oil and filter quality and/or viscosity is not
covered by the NISSAN New Vehicle Limited
Warranty.
Your engine was filled with a high-quality
engine oil when it was built. You do not have
to change the oil before the first recom-
mended change interval. Oil and filter
change intervals depend upon how you
use your vehicle.
NISSAN recommends the use of Genuine
NISSAN parts or equivalent. The use of
parts that do not meet or exceed NISSAN
specifications, can cause damage to your
vehicle, and have an effect on your war-
ranty coverage. It is recommended that
you visit a NISSAN dealer parts department
who can provide information on the proper
parts for your vehicle.Operation under the following conditions
may require more frequent oil and filter
changes:
• repeated short distance driving at cold
outside temperatures
• driving in dusty conditions
• extensive idling
• towing a trailer
• stop and go commuting
For additional information, refer to the
“Maintenance and schedules” section of
this manual.
AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your
NISSAN vehicle must be charged with the
refrigerant HFC-134a (R-134a) and
NISSAN A/C system oil Type PAG (DH-PR)
or the exact equivalents.
CAUTION
The use of any other refrigerant or oil
will cause severe damage to the air
conditioning system and will require
the replacement of all air conditioner
system components. The refrigerant HFC-134a (R-134a) in your
NISSAN vehicle does not harm the earth's
ozone layer. Although this refrigerant does
not affect the earth's atmosphere, certain
government regulations require the recov-
ery and recycling of any refrigerant during
automotive air conditioner system service.
A NISSAN dealer has the trained techni-
cians and equipment needed to recover
and recycle your air conditioner system re-
frigerant.
It is recommended that you visit a NISSAN
dealer when servicing your air conditioner
system.
