CAUTION
• Do not ground accessories directly to
the battery terminal. Doing so will
bypass the variable voltage control
system and the vehicle battery may
not charge completely.
• Use electrical accessories with the
engine running to avoid discharging
the vehicle battery.
NOTE:
If the battery is dead the transmission
will not manually shif t into another
position.
Your vehicle is equipped with a variable
voltage control system. This system mea-
sures the amount of electrical discharge
from the battery and controls voltage gen-
erated by the generator.
The current sensor is located near the bat-
tery along the negative battery cable. If you
add electrical accessories to your vehicle,
be sure to ground them to a suitable body
ground such as the frame or engine block
area.

REPLACING SPARK PLUGS
Iridium-tipped spark plugs
It is not necessary to replace iridium-
tipped spark plugs as frequently as con-
ventional type spark plugs because they
last much longer. Follow the maintenance
log shown in the “Maintenance and sched-
ules” section of this manual. Do not service
iridium-tipped spark plugs by cleaning or
regapping.
•Always replace spark plugs with rec-
ommended or equivalent ones.
WARNING
Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.
CAUTION
Be sure to use the correct socket to re-
move the spark plugs. An incorrect
socket can damage the spark plugs.
If replacement is required, it is recom-
mended that you visit a NISSAN dealer for
this service.

•Improper service of the spare
tire may result in serious per-
sonal injury. If it is necessary to
repair the spare tire, it is rec-
ommended that you visit a
NISSAN dealer for this service.
• For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.
Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. Rec-
ommended types and sizes are shown in
“Wheels and tires” (P. 8-35).
WARNING
• The use of tires other than those rec-
ommended or the mixed use of tires
of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the
ride, braking, handling, Vehicle Dy-
namic Control (VDC) system, 4WD,
ground clearance, body-to-tire clear-
ance, tire chain clearance, speedom-
eter calibration, headlight aim and
bumper height. Some of these ef-
fects may lead to accidents and
could result in serious personal
injury.
• If your vehicle was originally
equipped with four tires that were
the same size and you are only re-
placing two of the four tires, install
the new tires on the rear axle. Placing
new tires on the front axle may cause
loss of vehicle control in some driving
conditions and cause an accident
and personal injury. •
If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear, de-
grade vehicle handling characteris-
tics, affect the VDC system and/or in-
terference with the brake discs. Such
interference can lead to decreased
braking efficiency and/or early brake
pad/shoe wear. For additional infor-
mation on wheel-off set dimensions,
see “Wheels and tires” (P. 10-9).
• When using a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire
pressure warning light will flash for
approximately 1 minute. The light will
remain on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN
dealer for this service.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
• The TPMS sensor may be damaged if
it is not handled correctly. Be careful
when handling the TPMS sensor.
Do-it-yourself8-45

•When replacing the TPMS sensor, the
ID registration may be required. Con-
tact a NISSAN dealer for ID
registration.
• Do not use a valve stem cap that is
not specified by NISSAN. The valve
stem cap may become stuck.
• Be sure that the valve stem caps are
correctly fitted. Otherwise the valve
may be clogged up with dirt and
cause a malfunction or loss of
pressure.
• Do not install a damaged or de-
formed wheel or tire even if it has
been repaired. Such wheels or tires
could have structural damage and
could fail without warning.
• The use of retread tires is not
recommended.
• For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.Four-wheel drive models
CAUTION
Always use tires of the same type, size,
brand, construction (bias, bias-belted
or radial), and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tires
on the front and rear axles which will
cause excessive tire wear and may
damage the transmission, transfer
case and differential gears.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked
and corrected as necessary. It is recom-
mended that you visit a NISSAN dealer for
this service.
Wheel balance
Unbalanced wheels may affect vehicle
handling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle. Spin balancing the wheels on the vehicle
could lead to mechanical damage.
•
For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
Care of wheels
• Wash the wheels when washing the ve- hicle to maintain their appearance.
• Clean the inner side of the wheels when the wheel is changed or the underside of
the vehicle is washed.
• Do not use abrasive cleaners when washing the wheels.
• Inspect wheel rims regularly for dents or corrosion. Such damage may cause loss
of pressure or poor seal at the tire bead.
• NISSAN recommends waxing the road wheels to protect against road salt in ar-
eas where it is used during winter.
Spare tire (FULL SIZE TEMPORARY
USE ONLY spare tire)
When replacing a wheel without the TPMS
such as the spare tire, the TPMS will not
function.
