REPLACING SPARK PLUGS
Iridium-tipped spark plugs
It is not necessary to replace iridium-
tipped
Aspark 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.
WARNING
∙ Operating the engine with the air cleaner filter off can cause you or oth-
ers to be burned. The air cleaner filter
not only cleans the intake air, it also
stops the flame if the engine back-
fires. If the air cleaner is not installed
and the engine backfires, you could be
burned. Never drive with the air
cleaner filter off. Be cautious working
on the engine when the air cleaner is
off. ∙ 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.
To remove the filter from the air cleaner,
push the tabs
Aand pull the cover up-
ward.
The viscous paper type filter element
should not be cleaned and reused. Replace
the air filter according to the maintenance
log shown in the "Maintenance and sched-
ules" section of this manual.
When replacing the air filter, wipe the inside
of the air cleaner housing and the cover
with a damp cloth.
NOTE:
Af ter installing a new air cleaner, make
sure the air cleaner cover is seated in the
housing and latch the clips

Af termarket fuel additives
NISSAN does not recommend the use of
any af termarket fuel additives (for ex-
ample, fuel injector cleaner, octane
booster, intake valve deposit removers,
etc.) which are sold commercially. Many of
these additives intended for gum, varnish
or deposit removal may contain active sol-
vents or similar ingredients that can be
harmful to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended can
cause persistent, heavy “spark knock.”
(“Spark knock” is a metallic rapping
noise.) If severe, this can lead to engine
damage. If you detect a persistent heavy
spark knock even when using gasoline
of the stated octane rating, or if you hear
steady spark knock while holding a
steady speed on level roads, it is recom-
mended that you have a NISSAN dealer
correct the condition. Failure to correct
the condition is misuse of the vehicle, for
which NISSAN is not responsible.Incorrect ignition timing may result in
spark knock, af ter-run and/or overheating,
which may cause excessive fuel consump-
tion or engine damage. If any of the above
symptoms are encountered, have your ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for servicing.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not
a cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.

WARNING
Trailer hitch components have specific
weight ratings. Your vehicle may be ca-
pable of towing a trailer heavier than
the weight rating of the hitch compo-
nents. Never exceed the weight rating
of the hitch components. Doing so can
cause serious personal injury or prop-
erty damage.
Hitch ball
Choose a hitch ball of the proper size and
weight rating for your trailer:∙ The required hitch ball size is stamped on most trailer couplers. Most hitch
balls also have the size printed on the
top of the ball.
∙ Choose the proper class hitch ball based on the trailer weight.
∙ The diameter of the threaded shank of the hitch ball must be matched to the
ball mount hole diameter. The hitch ball
shank should be no more than 1/16”
smaller than the hole in the ball mount. ∙ The threaded shank of the hitch ball
must be long enough to be properly
secured to the ball mount. There should
be at least 2 threads showing beyond
the lock washer and nut.
Ball mount
The hitch ball is attached to the ball mount
and the ball mount is inserted into the
hitch receiver. Choose a proper class ball
mount based on the trailer weight. Addi-
tionally, the ball mount should be chosen to
keep the trailer tongue level with the
ground.
Weight carrying hitches
A weight carrying or “dead weight” ball
mount is one that is designed to carry the
whole amount of tongue weight and gross
weight directly on the ball mount and on
the receiver.
Weight distribution hitch
This type of hitch is also called a “load-
leveling” or “equalizing” hitch. A set of bars
attach to the ball mount and to the trailer
to distribute the tongue weight (hitch
weight) of your trailer. Many vehicles can’t
carry the full tongue weight of a given
trailer, and need some of the tongue weight transferred through the frame and
pushing down on the front wheels. This
gives stability to the tow vehicle.
A weight-distributing hitch system (Class
IV) is recommended if you plan to tow trail-
ers with a maximum weight over 5,000 lbs.
(2,268 kg). Check with the trailer and towing
equipment manufacturers to determine if
they recommend the use of a weight-
distributing hitch system.
NOTE:
A weight-distributing hitch system may
affect the operation of trailer surge
brakes. If you are considering use of a
weight-distributing hitch system with a
surge brake-equipped trailer, check with
the surge brake, hitch or trailer manufac-
turer to determine if and how this can be
done.
Follow the instructions provided by the
manufacturer for installing and using the
weight-distributing hitch system.
General set-up instructions are as follows:
1. Park unloaded vehicle on a level sur- face. With the ignition on and the doors
closed, allow the vehicle to stand for
several minutes so that it can level.
Technical and consumer information10-23

∙ NISSAN recommends that the cruisecontrol not be used while towing a
trailer.
∙ Some states or provinces have specific regulations and speed limits for ve-
hicles that are towing trailers. Obey the
local speed limits.
∙ Check your hitch, trailer wiring harness connections, and trailer wheel lug nuts
af ter 50 miles (80 km) of travel and at
every break.
∙ When launching a boat, don’t allow the water level to go over the exhaust tail
pipe or rear bumper.
∙ Make sure you disconnect the trailer lights before backing the trailer into the
water or the trailer lights may burn out.
When towing a trailer, final drive gear oil
should be replaced and transmission
oil/fluid should be changed more fre-
quently. For additional information, refer
to the “Do-it-yourself ” section in this
manual.
Tow mode
Using tow mode is recommended when
pulling a heavy trailer or hauling a heavy
load. Press the TOW MODE switch to acti- vate tow mode. The indicator light on the
TOW MODE switch illuminates when tow
mode is selected. Press the TOW MODE
switch again to turn tow mode off. Tow
mode is automatically canceled when the
ignition switch is turned off.
Tow mode includes the following features:
∙ Grade logic — Adjusts transmission shif ts when pulling a trailer or hauling a
load up a grade.
∙ Downhill Speed Control (DSC) — auto- matically downshif ts when driving
down a grade with a trailer or heavy
load to help control vehicle speed.
Driving the vehicle in the tow mode with no
trailer/load or light trailer/light load will not
cause any damage. However, fuel
economy may be reduced and the
transmission/engine driving characteris-
tics may feel unusual.
When towing a trailer, final drive gear oil
should be replaced and transmission
oil/fluid should be changed more fre-
quently. For additional information, refer
to the “Do-it-yourself ” section of this
manual.
FLAT TOWING FOR 4–WHEEL DRIVE
VEHICLE (if so equipped)
Towing your vehicle with all four wheels on
the ground is sometimes called flat towing.
This method is sometimes used when
towing a vehicle behind a recreational ve-
hicle, such as a motor home.
CAUTION
∙ Failure to follow these guidelines can result in severe transmission damage.
∙ Never flat tow your 4-wheel drive (4WD) vehicle.
∙ DO NOT tow your 4-wheel drive (4WD) vehicle with any wheels on the
ground. Doing so may cause serious
and expensive damage to the
powertrain.
∙ For emergency towing procedures re- fer to “Towing recommended by
NISSAN” in the “In case of emergency ”
section of this manual.
