corrosive materials, check lubrication frequently.
Lights*:
Clean the headlights on a regular basis. Make
sure that the headlights, stop lights, tail lights,
turn signal lights, and other lights are all operat-
ing properly and installed securely. Also check
headlight aim.
Road wheel nuts (lug nuts)*:
When checking the tires, make sure no wheel
nuts are missing, and check for any loose wheel
nuts. Tighten if necessary.
Tire rotation*:
Tires should be rotated every 7,500 miles
(12,000 km). However, the timing for tire rotation
may vary according to your driving habits and
road surface conditions.
Tires*:
Check the pressure with a gauge often and
always prior to long distance trips. If necessary,
adjust the pressure in all tires, including the
spare, to the pressure specified. Check carefully
for damage, cuts or excessive wear.
Tire, wheel alignment and balance:
If the vehicle should pull to either side while
driving on a straight and level road, or if you
detect uneven or abnormal tire wear, there maybe a need for wheel alignment.
If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
For additional information regarding tires, refer to
“Tire Safety Information” in the Warranty Infor-
mation Booklet (Canada).
Windshield:
Clean the windshield on a regular basis. Check
the windshield at least every six months for
cracks or other damage. Have a damaged wind-
shield repaired by a qualified repair facility.
Windshield wiper blades*:
Check for cracks or wear if they do not wipe
properly.
Inside the vehicleThe maintenance items listed here should be
checked on a regular basis, such as when
performing periodic maintenance, cleaning the
vehicle, etc.
Accelerator pedal:
Check the pedal for smooth operation and make
sure the pedal does not catch or require uneven
effort. Keep the floor mats away from the pedal.Brake pedal and booster*:
Check the pedal for smooth operation and make
sure it has the proper distance under it when
depressed fully. Check the brake booster func-
tion. Be sure to keep floor mats away from the
pedal.
Brakes:
Check that the brakes do not pull the vehicle to
one side when applied.
Parking brake*:
Check that the lever has the proper travel and
make sure that the vehicle is held securely on a
fairly steep hill when only the parking brake is
applied.
Seat belts:
Check that all parts of the seat belt system (for
example, buckles, anchors, adjusters and retrac-
tors) operate properly and smoothly, and are
installed securely. Check the belt webbing for
cuts, fraying, wear or damage.
Seats:
Check seat position controls such as seat ad-
justers, seatback recliner, etc. to ensure they
operate smoothly and that all latches lock se-
curely in every position. Check that the head
restraints move up and down smoothly and that

HEADLIGHT AIMThe aim of the headlights may require adjust-
ment when replacing the headlight assembly or
when the vehicle’s front body has been repaired.
When the adjustment is required, follow these
procedures, or have them adjusted by a NISSAN
dealer.
Before performing the headlight aim adjustment:

Check the pressure of all tires for the correct
inflation pressure.

Check that the tools and spare tire are
stowed securely.
Check that the fuel and lubricants levels are
filled to correct capacities.

Unload all luggage and other items, which
may influence the vehicle’s height level.

Load a weight on the driver’s seat that is
equivalent to the weight of a driver.
Stopping the vehicle1. Park the vehicle on a level surface vertical to
the wall or screen to which the headlights will
be projected.
2. Move the vehicle close to the wall to deter-
mine the point P as shown in the illustration.The point P must be:
“H” is the distance between the headlight
center point to the level surface.
“W
L” is the distance between the left and
right headlight centers.
3. Mark point P on the wall or screen.
4. Back up the vehicle 5,000 mm (197.0 in,
16.4 ft) straight away from the wall or screen.
“L” is the distance between the wall or screen
to the vehicle’s front bumper.
5. Apply the parking brake.

TIRE PRESSURE
Tire inflation pressureCheck the tire pressures (including the
spare) often and always prior to long
distance trips. The recommended tire
pressure specifications are shown on the
F.M.V.S.S./C.M.V.S.S. label or the Tire
and Loading Information label (if so
equipped) under the “Cold Tire Pres-
sure” heading. The Tire and Loading In-
formation 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
driven over potholes or other objects
or if the vehicle strikes a curbwhile
parking.
The tire pressures should be checked
when the tires are cold. The tires are
considered COLD after the vehicle has
been parked for 3 or more hours, or
driven less than 1.6 km (1 mile) at mod-
erate speeds.Incorrect tire pressure, including un-
der inflation, may adversely affect
tire life and vehicle handling.
WARNING

Improperly inflated tires can fail
suddenly and cause an acci-
dent.

The Gross Vehicle Weight Rat-
ing (GVWR) is located on the
F.M.V.S.S./C.M.V.S.S. label. The
vehicle weight capacity is indi-
cated on the Tire and Loading
Information label (if so
equipped). Do not load your ve-
hicle beyond this capacity.
Overloading your vehicle may
result in reduced tire life, un-
safe operating conditions due
to premature tire failure, or un-
favorable handling characteris-
tics and could also lead to a
serious accident. Loading be-yond the specified capacity may
also result in failure of other
vehicle components.

Before taking a long trip, or
whenever you heavily load your
vehicle, use a tire pressure
gauge to ensure that the tire
pressures are at the specified
level.

Do not drive your vehicle over
137 km/h (85 MPH) unless it is
equipped with high speed rated
tires. Driving faster than 137
km/h (85 MPH) may result in
tire failure, loss of control and
possible injury.

For additional information re-
garding tires, refer to “Tire
Safety Information” in the War-
ranty Information Booklet.

Checking the tire pressure1. Remove the valve stem cap from the
tire.
2. Press the pressure gauge squarely
onto the valve stem. Do not press too
hard or force the valve stem sideways,
or air will escape. If the hissing sound
of air escaping from the tire is heard
while checking the pressure, reposi-
tion the gauge to eliminate this leak-
age.3. Remove the gauge.
4. Read the tire pressure on the gauge
stem and compare it to the specifica-
tion shown on the Tire and Loading
Information label.
5. Add air to the tire as needed. If too
much air is added, press the core of
the valve stem briefly with the tip of the
gauge stem to release pressure. Re-
check the pressure and add or release
air as needed.
6. Install the valve stem cap.
7. Check the pressure of all other tires,
including the spare.

TIRE LABELINGFederal law requires tire manufacturers
to place standardized information on the
sidewall of all tires. This information iden-
tifies and describes the fundamental
characteristics of the tire and also pro-
vides the tire identification number (TIN)
for safety standard certification. The TIN
can be used to identify the tire in case of
a recall in case of recall.
1
Tire size (example: P215/65R15
95H)
1. P: The “P” indicates the tire is de-
signed for passenger vehicles. (Not all
tires have this information.)
2. Three-digit number (215): This num-
ber gives the width in millimeters of the
tire from sidewall edge to sidewall
edge.
3. Two-digit number (65): This number,
known as the aspect ratio, gives thetire’s ratio of height to width.
4. R: The “R” stands for radial.
5. Two-digit number (15): This number is
the wheel or rim diameter in inches.
6. Two- or three-digit number (95): This
number is the tire’s load index. It is a
measurement of how much weight
each tire can support. You may not
find this information on all tires be-
cause it is not required by law.
7. H: Tire speed rating. You should not
drive the vehicle faster than the tire
speed rating.

1. DOT: Abbreviation for the “Depart-
ment Of Transportation”. The
symbol can be placed above,
below or to the left or right of the
Tire Identification Number.
2. Two-digit code: Manufacturer’s identi-
fication mark
3. Two-digit code: Tire size4. Three-digit code: Tire type code (Op-
tional)
5. Three-digit code: Date of Manufacture
6. Four numbers represent the week and
year the tire was built. For example, the
numbers 3103 means the 31st week
of 2003. If these numbers are missing,
then look on the other sidewall of the
tire.
3
Tire ply composition and material
The number of layers or plies of
rubber-coated fabric in the tire. Tire
manufacturers also must indicate the
materials in the tire, which include
steel, nylon, polyester, and others.
4
Maximum permissible inflation pres-
sure
This number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure.
5
Maximum load rating
This number indicates the maximumload in kilograms and pounds that
can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.
6
Term of “tubeless” or “tube type”
Indicates whether the tire requires an
inner tube (“tube type”) or not
(“tubeless”).
7
The word “radial”
The word “radial” is shown if the tire
has radial structure.
