2002 NISSAN XTERRA check engine

If any driveability problems such as engine
stalling and hard hot starting are experi-
enced 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
refueling. Gasoline containing oxygen-
ates can cause paint damage.
After Market Fuel Additives
NISSAN does not recommend the use of
any fuel additives (i.e., fuel injector cleaner,
octane booster, intake valve deposit remov-
ers, 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
In most parts of North America, you should
use unleaded gasoline with an octane rating
of at least 87 (except supercharger) or 91
(supercharger) AKI (Anti-Knock Index).
However, you may use unleaded gasoline
with an octane rating as low as 85 AKI in
high altitude areas (over 4,000 ft [1,219 m])
such as: Colorado, Montana, New Mexico,
Utah, Wyoming, northeastern Nevada,southern Idaho, western South Dakota,
western Nebraska, and the part of Texas
which is directly south of New Mexico.
Using unleaded gasoline with an octane
rating lower than stated above 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, have an authorized NIS-
SAN dealer correct the condition. Failure
to correct the condition is misuse of the
vehicle, for which NISSAN is not respon-
sible.
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 symp-
toms are encountered, have your vehicle
checked at an authorized NISSAN dealer.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is
no cause for concern, because you get
the greatest fuel benefit when there islight spark knock for a short time under
heavy engine load.

4) Connect the tow harness connector
(SAE J1239) to your trailer.
5) Confirm proper vehicle and trailer
stop/turn lamp operation.
6) When towing is completed, disconnect
the tow harness from the trailer and the
vehicle. Store the tow harness in the
glove box. Reinstall the connector cap to
the vehicle harness.
If you need further assistance in wiring
a trailer to your NISSAN, contact an autho-
rized NISSAN dealer.
Always confirm proper vehicle and
trailer stop/turn lamp operation every
time the trailer light circuits are con-
nected for use.
Trailer brakes
If your trailer is equipped with a braking
system, make sure it conforms to Federal
and/or local regulations and that it is prop-
erly installed.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.
Pre-towing tips
OBe certain your vehicle maintains a level
position when a loaded and/or unloaded
trailer is hitched. Do not drive the vehicle
if it has an abnormal nose-up or nose-
down condition; check for improper
tongue load, overload, worn suspension
or other possible causes of either condi-
tion.
OAlways secure items in the trailer to
prevent load shift while driving.
OBe certain your outside mirrors conform
to all federal, state or local regulations. If
not, install any mirrors required for towing
before driving the vehicle.
Trailer towing tips
In order to gain skill and an understanding
of the vehicle's behavior, you should prac-
tice turning, stopping and backing up in an
area which is free from traffic. Steering,
stability and braking performance will be
somewhat different than under normal driv-
ing conditions.
OAlways secure items in the trailer to
prevent load shift while driving.
O
Avoid abrupt starts, acceleration or stops.
OAvoid sharp turns or lane changes.
OAlways drive your vehicle at a moderate
speed.
OAlways block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if
you must do so, and if your vehicle is
equipped with automatic transmission,
first block the wheels and apply the park-
ing brake, and then move the transmis-
sion shift selector lever into the P (Park)
position. If you move the shift lever to the
P (Park) position before blocking the
wheels and applying the parking brake,
transmission damage could occur.
OWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, downshift
the transmission to a lower gear and
reduce speed to reduce chances of en-
gine overloading and/or overheating.
However, for long steep grades, do not
stay in 1st or 2nd gear when driving
above 35 MPH (56 km/h).
OIf the engine coolant rises to an ex-
tremely high temperature when the air
conditioning system is on, turn off the air
conditioner. Coolant heat can be addi-
