2001 NISSAN XTERRA fuel

OKeep your engine tuned up.
OFollow the recommended periodic main-
tenance schedule.
OKeep the tires inflated to the correct
pressure. Low tire pressure increases
tire wear and wastes fuel.
OKeep the front wheels in correct align-
ment. Improper alignment increases tire
wear and lowers fuel economy.
OAir conditioner operation lowers fuel
economy. Use the air conditioner only
when necessary.
OWhen cruising at highway speeds, it is
more economical to use the air condi-
tioner and leave the windows closed to
reduce drag.
O
Use 4H or 4L position only when neces-
sary. Four-wheel drive operation lowers
fuel economy.
TRANSFER CASE SHIFTING
PROCEDURES
CAUTION
Do not drive on dry, hard surface roadsin four-wheel drive. Driving on dry
hardsurfaces in 4H or 4L may cause
unnecessary noise, tire wear and in-
creased fuel consumption. NISSAN
recommends driving in the 2H position
under these conditions.
WARNING
OWhen parking the vehicle, apply the
parking brake and shift the transfer
control lever into the 2H, 4H or 4L
position.
ODo not leave the transfer control le-
ver in the N (Neutral) position. Oth-
erwise, the vehicle could roll unex-
pectedly even if the manual
transmission is in any gear or the
automatic transmission is in the P
(Park) position. If the ATP light is on,
this indicates that the automatic
transmission P position will not
function and the transfer control le-
ver is in the N position.

TO SHIFT
TRANSFER CASE:SHIFT PROCEDURE FOR AUTO-LOCK FREE-RUNNING HUBS
From 2H to 4HMove the transfer case shift lever to 4H at speeds below 25 MPH (40 km/h). It is not necessary to depress the clutch pedal. Perform
this operation when driving straight, not while cornering.
From 4H to 2H1. Move the transfer case shift lever to 2H. This can be done at any speed, and it is not necessary to depress the clutch pedal. Per-
form this operation when driving straight, not while cornering.
2. Disengage the AUTO-LOCK hubs following the procedure outlined below.
NOTE:
The 4WD indicator light may not turn off immediately under certain driving conditions, such as when the vehicle is driven
uphill. This is normal and it will shut off as the vehicle is driven further.
AUTO-LOCK HUB DISENGAGEMENT (FREE MODE)
The AUTO-LOCK hubs will not disengage until the vehicle is completely stopped and is then moved in a straight line, approximately
7-10 feet (2-3 m), in the opposite direction of travel. For example:
If you were driving the vehicle forward, stop and move the vehicle 7-10 feet (2-3 m) backward.
If you were driving the vehicle in reverse, stop and move the vehicle 7-10 feet (2-3 m) forward.
It is not necessary to immediately return the AUTO-LOCK hubs to FREE MODE when shifting from 4H to 2H. The vehicle may be
operated under normal 2H conditions with the AUTO-LOCK hubs engaged. However, disengaging the AUTO-LOCK hubs will allow
for better fuel economy, quieter ride and less component wear. Leaving the hubs locked while driving in 2H may be desirable so that
you can easily shift to 4H at speeds greater than 25 MPH (40 km/h).
From 4H to 4L or 4L to
4H1. Stop the vehicle.
2. Depress the clutch pedal, or place the transmission selector lever in the N (Neutral) position.
3. Depress the transfer case shift lever and move it to the 4L or 4H position. Change gears quickly and smoothly.
From 2H to 4L1. Stop the vehicle.
2. Depress the clutch pedal, or place the transmission selector lever in the N (Neutral) position.
3. Depress the transfer case shift lever and move it to the 4L position. Change gears quickly and smoothly.
From 4L to 2H1. Stop the vehicle.
2. Depress the clutch pedal, or place the transmission selector lever in the N (Neutral) position.
3. Depress the transfer case shift lever and move it to the 2H position. Change gears quickly and smoothly.
4. Disengage the AUTO-LOCK hubs following the procedure outlined above.

CAUTION
ONEVER remove dirt, sand or other
debris from the passenger compart-
ment by washing it out with a hose.
Remove dirt with a vacuum cleaner
or broom.
ONever allow water or other liquids to
come in contact with electronic com-
ponents inside the vehicle as this
may damage them.
Chemicals used for road surface de-icing
are extremely corrosive. They accelerate
corrosion and deterioration of underbody
components such as the exhaust system,
fuel and brake lines, brake cables, floor pan
and fenders.
In winter, the underbody must be
cleaned periodically.
For additional protection against rust and
corrosion, which may be required in some
areas, consult an authorized NISSAN
dealer.
7-6Appearance and care
ZX

When performing any inspection or mainte-
nance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
OPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For manual trans-
mission models, move the shift lever
to N (Neutral). For automatic trans-
mission models, move the shift lever
to P (Park).
OBe sure the ignition key is in the OFF
or LOCK position when performing
any parts replacement or repairs.
ONever leave the engine or automatic
transmission related component
harnesses disconnected while the
ignition switch is in the ON position.
ONever connect or disconnect the bat-
tery or any transistorized compo-
nent while the ignition switch is in
the ON position.O
If you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans,
belts, and any other moving parts.
OIt is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
OAlways wear eye protection when-
ever you work on your vehicle.
OIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
ONever get under the vehicle while it
is supported only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
OKeep smoking materials, flame and
sparks away from the fuel tank and
battery.
OOn gasoline engine models with the
multiport fuel injection (MFI) system,
the fuel filter or fuel lines should be
serviced by an authorized NISSAN
dealer because the fuel lines are
under high pressure even when the
engine is off.
CAUTION
ODo not work under the hood while
the engine is hot. Turn the engine off
and wait until it cools down.
ONever connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion is on.
OAvoid contact with used engine oil
and coolant. Improperly disposed
engine oil, engine coolant and/or
other vehicle fluids can damage the
environment. Always conform to lo-
cal regulations for disposal of ve-
hicle fluid.
This ``Do-it-yourself'' section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect your warranty coverage.If in
doubt about any servicing, have it done
by an authorized NISSAN dealer.
