CAUTION
• Do not push start this vehicle. The
three-way catalyst may be
damaged.
• Automatic transmission models can-
not be push-started or tow-started.
Attempting to do so may cause
transmission damage.WARNING
• Do not continue to drive if your ve-
hicle overheats. Doing so could cause
engine damage or a vehicle fire.
• To avoid the danger of being scalded,
never remove the radiator or coolant
reservoir cap while the engine is still
hot. When the radiator or coolant res-
ervoir cap is removed, pressurized
hot water will spurt out, possibly
causing serious injury.
• Do not open the hood if steam is
coming out.
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.
1. Move the vehicle safely off the road, ap- ply the parking brake and move the shif t
lever to P (Park).
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed. 3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the ra-
diator before opening the hood. If steam
or coolant is escaping, turn off the en-
gine. Do not open the hood further until
no steam or coolant can be seen.
4. Open the engine hood.

WARNING
Do not allow wet seat belts to roll up in
the retractor. NEVER use bleach, dye or
chemical solvents to clean the seat
belts, since these materials may se-
verely weaken the seat belt webbing.MOST COMMON FACTORS
CONTRIBUTING TO VEHICLE
CORROSION
Most vehicle corrosion is caused by:
• The accumulation of moisture-retaining dirt and debris in body panel sections,
cavities, and other areas.
• Damage to paint and other protective coatings caused by gravel and stone
chips or minor traffic collisions.
ENVIRONMENTAL FACTORS
INFLUENCE THE RATE OF
CORROSION
Moisture
Accumulation of sand, dirt and water on
the vehicle body underside can accelerate
corrosion. Wet floor coverings will not dry
completely inside the vehicle and should
be removed for drying to avoid floor panel
corrosion.
Relative humidity
Corrosion will be accelerated in areas of
high relative humidity, especially those ar-
eas where the temperatures stay above
freezing and where atmospheric pollution
exists and road salt is used.
Temperature
High temperatures accelerate the rate of
corrosion to those parts which are not well
ventilated.
Air pollution
Industrial pollution, the presence of salt in
the air in coastal areas, or heavy road salt
use accelerates the corrosion process.
Road salt also accelerates the disintegra-
tion of paint surfaces.
PROTECT YOUR VEHICLE FROM
CORROSION
• Wash and wax your vehicle of ten to keepthe vehicle clean.
• Always check for minor damage to the paint and repair it as soon as possible.
• Keep drain holes at the bottom of the doors open to avoid water accumulation.
• Check the underbody for accumulation of sand, dirt or salt. If present, wash with
water as soon as possible.

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir
when the engine is cold. If the coolant
level is below the MIN level
OB, add coolant
to the MAX level
OA. If the reservoir is empty,
check the coolant level in the radiator
when the engine is cold. If there is insuffi-
cient coolant in the radiator, fill the radiator
with coolant up to the filler opening and
also add it to the reservoir up to the MAX
level
OA. This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue). The life ex-
pectancy of the factory-fill coolant is
105,000 miles (168,000 km) or 7 years. Mixing
any other type of coolant or the use of
non-distilled water will reduce the life ex-
pectancy of the factory-fill coolant. For ad-
ditional information, refer to the "Mainte-
nance and schedules" section of this
manual.
If the cooling system frequently requires
coolant, it is recommended that you visit
a NISSAN dealer for this service.
For additional information on the location
of the engine coolant reservoir, refer to “En-
gine compartment check locations” in this
section.
CHANGING ENGINE COOLANT
A NISSAN dealer can change the engine
coolant. The service procedure can be
found in the NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine over-
heating.
WARNING
• To avoid the danger of being scalded,
never change the coolant when the
engine is hot.
• Never remove the radiator or engine
coolant reservoir cap when the en-
gine is hot. Serious burns could be
caused by high pressure fluid escap-
ing from the radiator.
• Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand
cleaner as soon as possible.
• Keep coolant out of the reach of chil-
dren and pets.
Engine coolant must be disposed of prop-
erly. Check your local regulations.
LDI2831

CAUTION
Be careful not to burn yourself, as the
engine oil is hot.
WARNING
• Prolonged and repeated contact
with used engine oil may cause skin
cancer.
• Try to avoid direct skin contact with
used oil. If skin contact is made, wash
thoroughly with soap or hand
cleaner as soon as possible.
• Keep used engine oil out of reach of
children.
4. Loosen the oil filter with an oil filter wrench by turning it counterclockwise.
Remove the oil filter by turning it by
hand.
5. Wipe the engine oil filter mounting sur- face with a clean rag.

If the fluid is cold and is at or below the
COLD MIN line, add Genuine NISSAN PSF-II
or equivalent to the COLD MAX line. If the
fluid is hot and below the HOT MAX line, add
Genuine NISSAN PSF-II or equivalent to the
HOT MAX line. Remove the cap and fill
through the opening.
CAUTION
Do not spill the fluid on any painted sur-
faces. This will damage the paint. If fluid
is spilled, immediately wash the sur-
face with water.
BRAKE FLUID
Check the brake fluid level in the reservoir. If
the fluid level is below the MIN line
OBor the
brake warning light comes on, add Genu-
ine NISSAN Super Heavy Duty Brake Fluid or
equivalent DOT 3fluid up to the MAX line
OA.
If fluid must be added frequently, the sys-
tem should be checked. It is recom-
mended that you visit a NISSAN dealer for
this 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.
WARNING
• Do not expose the battery to flames,
an electrical spark or a cigarette. Hy-
drogen gas generated by the battery
is explosive. Explosive gases can
cause blindness or injury. Do not al-
low battery fluid to contact your skin,
eyes, fabrics or painted surfaces. Sul-
furic acid can cause blindness or in-
jury. Af ter touching a battery or bat-
tery cap, do not touch or rub your
eyes. Thoroughly wash your hands. If
the acid contacts your eyes, skin or
clothing, immediately flush with wa-
ter for at least 15 minutes and seek
medical attention.
• When working on or near a battery,
always wear suitable eye protection
and remove all jewelry.
• Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands af ter
handling.
• Keep battery out of the reach of
children.
• Do not tip the battery.

TPMS will activate only when the vehicle is
driven at speeds above 16 mph (25 km/h).
Also, this system may not detect a sudden
drop in tire pressure (for example, a flat tire
while driving).
For additional information, refer to “Low tire
pressure warning light” in the “Instruments
and controls” section, “Tire Pressure Moni-
toring System (TPMS)” in the “Starting and
driving” section, and “Flat tire” in the “In case
of emergency” section of this manual.
Tire inflation pressure
Check the tire pressures (including the
spare) of ten and always prior to long dis-
tance trips. The recommended tire pres-
sure specifications are shown on the
F.M.V.S.S./C.M.V.S.S. certification label or the
Tire and Loading Information label under
the “Cold Tire Pressure” heading. The Tire
and Loading Information label is affixed to
the driver side center pillar. Tire pressures
should be checked regularly because:
• Most tires naturally lose air over time.
• Tires can lose air suddenly when drivenover potholes or other objects or if the
vehicle strikes a curb while parking. The tire pressures should be checked
when the tires are cold. The tires are con-
sidered COLD af ter the vehicle has been
parked for 3 or more hours, or driven less
than 1 mile (1.6 km) at moderate speeds.
Incorrect tire pressure, including under
inflation, may adversely affect tire life
and vehicle handling.
WARNING
• Improperly inflated tires can fail sud-
denly and cause an accident.
• The Gross Vehicle Weight Rating
(GVWR) is located on the F.M.V.S.S./
C.M.V.S.S. certification label. The ve-
hicle weight capacity is indicated on
the Tire and Loading Information la-
bel. Do not load your vehicle beyond
this capacity. Overloading your ve-
hicle may result in reduced tire life,
unsafe operating conditions due to
premature tire failure, or unfavorable
handling characteristics and could
also lead to a serious accident. Load-
ing beyond the specified capacity
may also result in failure of other ve-
hicle components. •
Before taking a long trip, or when-
ever you heavily load your vehicle,
use a tire pressure gauge to ensure
that the tire pressures are at the
specified level.
• For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
