REPLACING SPARK PLUGS
Platinum-tipped spark plugsIt is not necessary to replace the platinum-tippedAspark plugs as frequently as the conventional
type spark plugs since they will last much longer.
Follow the maintenance log, but do not reuse
them by cleaning or regapping.
If replacement is required, see a NISSAN dealer
for servicing.
Always replace with recommended
platinum-tipped spark plugs.To remove the filter from the air cleaner, push
down the lock pins
1
and pull the unit upward
2.
The filter element should not be cleaned and
reused. Replace it according to the maintenance
log shown in the separate Service and Mainte-
nance Guide. When replacing the filter, wipe the
inside of the air cleaner housing and the cover
with a damp cloth.
WARNING
Operating the engine with the aircleaner removed can cause you or
others to be burned. The air cleaner
not only cleans the air, it stops the
flame if the engine backfires. If it isn’t
there, and the engine backfires, you
could be burned. Do not drive with
the air cleaner removed, and be care-
ful when working on the engine with
the air cleaner removed.
Never pour fuel into the throttle body
or attempt to start the engine with
the air cleaner removed. Doing so
could result in serious injury.

The disc-type brakes self-adjust every time the
brake pedal is applied.
WARNING
See a NISSAN dealer and have it
checked if the brake pedal height does
not return to normal.Brake pad wear indicatorsThe disc brake pads on your vehicle have au-
dible wear indicators. When a brake pad re-
quires replacement, it will make a high pitched
scraping or screeching sound when the vehicle
is in motion whether or not the brake pedal is
depressed. Have the brakes checked as soon as
possible if the wear indicator sound is heard.
Under some driving or climate conditions, occa-
sional brake squeak, squeal or other noise may
be heard. Occasional brake noise during light to
moderate stops is normal and does not affect
the function or performance of the brake system.
Proper brake inspection intervals should
be followed.For additional information, see the
separate Service and Maintenance Guide.
BRAKE BOOSTERCheck the brake booster function as follows:
1. With the engine off, depress and release the
brake pedal several times. When brake pedal
movement (distance of travel) remains the
same from one pedal application to the next,
continue on to the next step.
2. While depressing the brake pedal, start the
engine. The pedal height should drop a little.
3. With the brake pedal depressed, stop the
engine. Keeping the pedal depressed for
about 30 seconds, the pedal height should
not change.
4. Run the engine for one minute without de-
pressing the brake pedal, then turn it off.
Depress the brake pedal several times. The
pedal travel distance will decrease gradually
with each depression as the vacuum is re-
leased from the booster.
If the brakes do not operate properly, see a
NISSAN dealer.Some vehicles are equipped with engine com-
partment and passenger compartment fuse
boxes that use only type
A
fuses. Other ve-
hicles are equipped with typeA
fuses in the
engine compartment fuse box and type
Bfuses
in the passenger compartment fuse box.
Type
Afuses are provided as spare fuses. They
are stored in the passenger compartment fuse
box.
Type
A
fuses can be installed in the engine
compartment and passenger compartment fuse
boxes.

WARNINGHIGH VOLTAGE
When xenon headlights are on, they
produce a high voltage. To prevent an
electric shock, never attempt to modify
or disassemble. Always have your xe-
non headlights replaced at a NISSAN
dealer. For additional information, see
“Headlight and turn signal switch” in
the “Instruments and controls” section.
Halogen headlight bulb:
The headlight is a semi-sealed beam type which
uses a replaceable headlight (halogen) bulb. If
replacement is required, see a NISSAN dealer.
CAUTION
High pressure halogen gas is sealed
inside the halogen bulb. The bulb
may break if the glass envelope is
scratched or the bulb is dropped.
When handling the bulb, do not touch
the glass envelope.
Do not touch the bulb.
Use the same number and wattage as
originally installed:

TIRE PRESSURE
Tire pressure monitoring system
(TPMS) (if so equipped)This vehicle is equipped with the tire pressure
monitoring system (TPMS). It monitors tire pres-
sure of all tires except the spare. When the low
tire pressure warning light is lit, one or more of
your tires is significantly under-inflated. If
equipped, the system also displays pressure of
all tires (except the spare tire) on the display
screen by sending a signal from a sensor that is
installed in each wheel.
The 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 more details, refer to “Low tire pressure
warning light” in the “2. Instruments and con-
trols” section, “Tire pressure information” in the
“4. Display screen, heater, air conditioner and
audio systems” section, “Tire pressure monitor-
ing system (TPMS)” in the “5. Starting and
driving” section, and “Flat tire” in the “6. In case
of emergency” section.

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
FMVSS label and/or the Tire and Loading
Information label under the “Cold Tire
(Inflation) Pressure” heading. The Tire
and Loading Information label is affixed to
the driver side center pillar. Tire pres-
sures should be checked regularly be-
cause:
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 mile (1.6 km) 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 is located on the FMVSS
label. The vehicle weight capac-
ity is indicated on the Tire and
Loading Information label. Do
not load your vehicle beyond
this capacity. Overloading your
vehicle may result in reduced
tire life, unsafe operating con-
ditions due to premature tire
failure, or unfavorable handling
characteristics and could also
lead to a serious accident.
Loading beyond the specified
capacity may also result in fail-ure of other vehicle compo-
nents.
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
85 MPH (137 km/h) unless it is
equipped with high speed rated
tires. Driving faster than 85
MPH (137 km/h) may result in
tire failure, loss of control and
possible injury.

garding tires, refer to “Impor-
tant Tire Safety Information”

WARNING
When changing or replacing tires, be
sure all four tires are of the same
type (for example, Summer, All Sea-
son or Snow) and construction. A
NISSAN dealer may be able to help
you with information about tire type,
size, speed rating and availability.
Replacement tires may have a lower
speed rating than the factory
equipped tires, and may not match
the potential maximum vehicle
speed. Never exceed the maximum
speed rating of the tire.
Replacing tires with those not origi-
nally specified by NISSAN could af-fect the proper operation of the tire
pressure monitoring system (TPMS).
(if so equipped)
For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
All season tiresNISSAN specifies All Season tires on some
models to provide good performance for use all
year, including snowy and icy road conditions.
All Season tires are identified by ALL SEASON
and/or M&S on the tire sidewall. Snow tires have
better snow traction than All Season tires and
may be more appropriate in some areas.Summer tiresNISSAN specifies summer tires on some models
to provide superior performance on dry roads.
Summer tire performance is substantially re-
duced in snow and ice. Summer tires do not
have the tire traction rating “M&S” on the tire
sidewall.
If you plan to operate your vehicle in snowy or icy
conditions, NISSAN recommends the use ofSNOW tires or ALL SEASON tires on all four
wheels.
Snow tiresIf snow tires are needed, it is necessary to select
tires equivalent in size and load rating to the
original equipment tires. If you do not, it can
adversely affect the safety and handling of your
vehicle.
Generally, snow tires will have lower speed
ratings than factory equipped tires and may not
match the potential maximum vehicle speed.
Never exceed the maximum speed rating of the
tire.
If you operate your vehicle in snowy or icy
conditions, NISSAN recommends the use of
snow or all season tires on all four wheels.
For additional traction on icy roads, studded tires
may be used. However, some U.S. states and
Canadian provinces prohibit their use. Check
local, state and provincial laws before installing
studded tires. Skid and traction capabilities of
studded snow tires on wet or dry surfaces may
be poorer than that of non-studded snow tires.

CHANGING WHEELS AND TIRES
Tire rotationNISSAN recommends rotating the tires
every 7,500 miles (12,000 km).
See “Flat tire” in the “6. In case of
emergency” section of this manual for tire
replacing procedures.
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.Wheel nut tightening torque:
80 ft-lb (108 N⋅m)
The wheel nuts must be kept tight-
ened to specifications at all times. It
is recommended that wheel nuts be
tightened to specification at each
tire rotation interval.
WARNING
After rotating the tires, check
and adjust the tire pressure.
Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).
Do not include the spare tire in
the tire rotation.
For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”

WARNING
Tires should be periodically in-
spected for wear, cracking,
bulging or objects caught in the
tread. If excessive wear, cracks,
bulging or deep cuts are found,the tire(s) should be replaced.
The original tires have built-in
tread wear indicators. When the
wear indicators are visible, the
tire(s) should be replaced.
Improper service of the spare
tire may result in serious per-
sonal injury. If it is necessary to
repair the spare tire, contact a
NISSAN dealer.

Replacing wheels and tiresWhen replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. Recommended types and
sizes are shown in “Wheels and tires” in the
“Technical and consumer information” section of
this manual.
WARNING
The use of tires other than those
recommended 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, ground clearance,
body-to-tire clearance, tire chain
clearance, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to
accidents and could result in serious
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 and/or interference with the
brake discs/drums. Such interfer-
ence can lead to decreased braking
efficiency and/or early brake
pad/shoe wear. Refer to “Wheels and
