2008 NISSAN FRONTIER ignition

REPLACING SPARK PLUGS
Platinum-tipped spark plugs (if so
equipped)
It is not necessary to replace platinum-tippedsA
spark plugs as frequently as conventional type
spark plugs because they last much longer. Fol-
low the maintenance log shown in the “NISSAN
Service and Maintenance Guide”. Do not service
platinum-tipped spark plugs by cleaning or re-
gapping.
cAlways 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.
Iridium-tipped spark plugs (if so
equipped)
It is not necessary to replace iridium-tippedsA
spark plugs as frequently as conventional type
spark plugs because they last much longer. Fol-
low the maintenance log shown in the “NISSAN
Service and Maintenance Guide”. Do not service
iridium-tipped spark plugs by cleaning or regap-
ping.
cAlways 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.

If any driveability problems such as engine stall-
ing and difficult hot-starting are experienced after
using oxygenate-blend fuels, immediately
change to a non-oxygenate fuel or a fuel with a
low blend of MTBE.
Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.
E–85 fuel
E-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV) . Do
not use E-85 in your vehicle. U.S. government
regulations require fuel ethanol dispensing
pumps to be identified by a small, square, orange
and black label with the common abbreviation or
the appropriate percentage for that region.
Aftermarket fuel additives
NISSAN does not recommend the use of any
aftermarket fuel additives (for example, fuel injec-
tor 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 solvents 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 se-
vere, 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, 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, after-run and/or overheating, which may
cause excessive fuel consumption or engine
damage. If any of the above symptoms are en-
countered, have your vehicle checked at a
NISSAN dealer.
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.
CAUTION
cYour vehicle is not designed to run on
E-85 fuel. Using E-85 fuel in a vehicle
not specifically designed for E-85 fuel
can damage fuel system components
and is not covered by the NISSAN new
vehicle limited warranty.
cE-85 is a mixture of approximately 85%
fuel ethanol and 15% unleaded
gasoline.
cU.S. government regulations require
ethanol dispensing pumps to be identi-
fied by a small, square, orange and
black label with the common abbrevia-
tion or the appropriate percentage for
that region.

Hitch ball
Choose a hitch ball of the proper size and weight
rating for your trailer:
cThe required hitch ball size is stamped on
most trailer couplers. Most hitch balls also
have the size printed on the top of the ball.
cChoose the proper class hitch ball based on
the trailer weight.
cThe 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.
cThe 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. Additionally, the ball mount should
be chosen to keep the trailer tongue level with the
ground.
Bumper towing
The genuine NISSAN step bumper has provi-
sions to install a trailer hitch ball and is designed
to tow trailers of a maximum weight of 3,500 lb
(1,588 kg) .
To install a trailer hitch ball cut out the circle in the
center of the step bumper
sA, then remove it to
install the trailer hitch ball.
Weight carrying hitches
A weight carrying or9dead weight9ball 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 ve-
hicles 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.
Another reason to have a weight distributing ball
mount is to comply with the rating on your re-
ceiver. Most receivers have a weight carrying
rating of 5,000 lbs. gross weight, 500 lbs. tongue
weight and a weight distribution rating of 10,000
lbs. gross weight, 1,000 lbs. tongue weight. This
means that without using a weight distributing
ballmount, the receiver is only designed to carry
5,000 lbs.
When hooking up a trailer using a weight distrib-
uting hitch, always refer to the hitch manufactur-
er’s instructions.
1. Park unloaded vehicle on a level surface.
With the ignition on and the doors closed,
allow the vehicle to stand for several minutes
so that it can level.

You may notify NISSAN by contacting our
Consumer Affairs Department, toll-free, at
1-800-NISSAN-1.Due to legal requirements in some states and
Canadian Provinces, your vehicle may be re-
quired to be in what is called the “ready condi-
tion” for an Inspection/Maintenance (I/M) test of
the emission control system.
The vehicle is set to the “ready condition” when it
is driven through certain driving patterns. Usually,
the ready condition can be obtained by ordinary
usage of the vehicle.
If a powertrain system component is repaired or
the battery is disconnected, the vehicle may be
reset to a “not ready” condition. Before taking the
I/M test, check the vehicle’s
inspection/maintenance test readiness condi-
tion. Turn the ignition switch ON without starting
the engine. If the Malfunction Indicator Light
(MIL) comes on steady for 20 seconds and then
blinks for 10 seconds , the I/M test condition is
9not ready9. If the MIL does not blink after 20
seconds, the I/M test condition is9ready.9If the
MIL indicates the vehicle is in a9not ready9con-
dition, drive the vehicle through the following
pattern to set the vehicle to the ready condition. If
you cannot or do not want to perform the driving
pattern, a NISSAN dealer can conduct it for you.
