REPLACING SPARK PLUGS
If replacement is required, it is recom-
mended you visit a NISSAN dealer for this
service.
Iridium-tipped spark plugs
It is not necessary to replace the iridium-
tipped spark plugs as frequently as the
conventional type spark plugs since they
will last much longer. Follow the main-
tenance schedule shown in the “9. Main-
tenance and schedules” section, but do
not reuse them by cleaning or regapping.
Always replace spark plugs with recom-
mended or equivalent ones.

To remove the filter, release the lock pinsand pull the unit upward.
The filter element should not be cleaned
and reused. Replace it according to the
maintenance schedule shown in the “9.
Maintenance and schedules” section.
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 air
cleaner removed can cause you
or others to be burned. The air
cleaner not only cleans the air, it stops flame if the engine back-
fires. If it isn’t there, and the
engine backfires, you could be
burned. Do not drive with the air
cleaner removed, and be careful
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 re-
moved. Doing so could result in
serious injury.

It is recommended you visit a NISSAN
dealer if checking or replacement is
required.If the brakes do not operate properly,
have the brakes checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjust-
ing brakes.
The disc-type brakes self-adjust every
time the brake pedal is applied.
WARNING
Have your brake system checked if
the brake pedal height does not
return to normal. It is recommended
you visit a NISSAN dealer for this
service.
BRAKE PAD WEAR WARNING
The disc brake pads have audible wear
warnings. When a brake pad requires
replacement, it will make a high pitched
scraping sound when the vehicle is in
motion. This scraping sound will first
occur only when the brake pedal is
depressed. After more wear of the brake
pad, the sound will always be heard even
if the brake pedal is not depressed. Have
the brakes checked as soon as possible if
the wear warning sound is heard.Under some driving or climate conditions,
occasional 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 infor-
mation, see the maintenance schedule
shown in the “9. Maintenance and sche-
dules” section.
BRAKE BOOSTER
Check the brake booster function as
follows:
1. With the engine off, depress and release the foot brake pedal more
than 20 times. When the foot 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 foot brake pedal, start the engine.
3. With the foot brake pedal depressed, stop the engine. Keep the pedal de-
pressed for about 30 seconds.
4. Run the engine for 1 minute without depressing the foot brake pedal, then
turn it off. Depress the foot brake
pedal several times. The pedal travel
distance will decrease gradually with

TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit and the “Tire Pressure
Low Add Air” warning appears in the
vehicle information display, one or more
of your tires is significantly under-inflated.
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, see “Low tire pressure
warning light” (P.2-15), “Tire Pressure Mon-
itoring System (TPMS)” (P.5-5) and “Tire
Pressure Monitoring System (TPMS) ” (P.6-
3).
Tire inflation pressure
Check the pressure of the tires
(including the spare) often and al-
ways prior to long distance trips.
The recommended tire pressure
specifications are shown on the
Tire and Loading Information label
under the “Cold Tire Pressure”
heading. The Tire and Loading In-
formation label is affixed to the
driver side center pillar. Tire pres-
sures 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 curb while 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 moderate speeds.
TPMS with Easy Fill Tire Alert pro-

outside the vehicle for inflating the
tires to the recommended COLD
tire pressure. (See “TPMS with Easy
Fill Tire Alert” (P.5-8).)
Incorrect tire pressure, including
under inflation, may adversely
affect tire life and vehicle hand-
ling.
WARNING
.Improperly inflated tires can
fail suddenly and cause an
accident.
. The Gross Vehicle Weight
rating (GVWR) is located on
the F.M.V.S.S./C.M.V.S.S. cer-
tification label. The vehicle
weight capacity is indicated
on the Tire and Loading In-
formation label. Do not load
your vehicle beyond this ca-
pacity. 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. Loading
beyond the specified capa-
city may also result in failure
of other vehicle compo-
nents.
. Before taking a long trip, or
whenever you heavily load
your vehicle, use a tire pres-
sure gauge to ensure that
the tire pressures are at the
specified level.
. For additional information
regarding tires, refer to “Im-
portant Tire Safety Informa-
tion” (US) or “Tire Safety
Information” (Canada) in the
Warranty Information Book-
let.

Checking the tire pressure
1. Remove the valve stem cap fromthe 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 pres-
sure, reposition the gauge to
eliminate this leakage. 3. Remove the gauge.
4. Read the tire pressure on the
gauge stem and compare it to
the specification 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. Recheck 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.
8. Check the pressure when driv- ing the vehicle at speeds of 100
MPH (160 km/h) or higher where
it is legal to do so.
WARNING
. Driving at high speeds, 100 MPH
(160 km/h) or higher sustained
where it is legal to do so, can
cause tires to have excessive heat build up, which may result in a
tire failure causing loss of control,
crash, injuries or even death.
Some high-speed rated tires re-
quire inflation pressure adjust-
ment for high-speed operation.
When speed limits and road con-
ditions allow vehicle driving at
high speeds, make sure tires are
rated to support high speed op-
eration, tires are in optimal con-
ditions and pressure is adjusted
to correct cold inflation pressure
for high speed operation.
. Tires require adjustment to the
inflation pressure when driving
the vehicle at speeds of 100 MPH
(160 km/h) or higher where it is
legal to do so. See recommended
tire inflation chart for correct
operating pressure.
. After vehicle high speed opera-
tion has ended, readjust the tire
pressure to the recommended
cold inflation pressure. (See
“Checking the tire pressure” (P.8-
31).)
