engine NISSAN XTERRA 2002 WD22 / 1.G Service Manual

OFailure to engage the transfer con-
trol lever in 2H, 4H, or 4L could result
in the vehicle moving unexpectedly,
resulting in serious personal injury
or property damage.
2HÐ (2WD, high range) Only the rear
wheels are driven. Use for driving under the
same conditions as standard 2WD vehicles
or state dynamometer I/M testing.
4HÐ (4WD, high range) Four wheels are
driven. Use when driving on roads where it
is difficult to drive in the 2H position (i.e.,
driving at normal speeds on snow covered,
icy, wet, muddy or sandy roads).
4LÐ (4WD, low range) Four wheels are
driven. Use when climbing or descending
steep hills, or during hard driving in sand,
mud or deep snow. The 4L position provides
maximum power and traction. Avoid raising
vehicle speed excessively, as the maximum
speed is approximately 30 MPH (48 km/h).
NÐ No wheels are driven. Always keep the
transfer lever out of the N (Neutral) position.
Shift the lever quickly and smoothly when
moving across the N (Neutral) position with
the vehicle stopped.
AUTO-LOCK FREE-
RUNNING HUBS
Your NISSAN is equipped with auto-lock
free-running hubs.
The auto-lock free-running hub is designed
to allow for automatic four-wheel drive en-
gagement when the shift lever is moved to
the 4H or 4L position. Follow these opera-
tional cautions:
CAUTION
OThe auto-locking hubs will make aclicking noise when engaging and
disengaging. This is normal.
OAccelerating quickly from a stop af-
ter shifting from two-wheel drive to
four-wheel drive may not allow en-
gagement of the auto-locking free-
running hubs and may cause a clat-
tering noise. Continued use of the
vehicle with this noise may damage
the hub lock. In such a case, release
the accelerator pedal to reduce the
engine speed or stop the vehicle.
OIf the auto-locking hubs make a clat-
tering noise after shifting from four-
wheel drive to two-wheel drive, stop
and move the vehicle in reverse
gear, in a straight line, about 7 to 10
feet (2 to 3 m).
OUnder extremely cold conditions
[below 5ÉF (-15ÉC)], the front axle
shafts may rotate even with the
transfer lever in the 2H position. If
this occurs, the auto-locking hubs
may make a clattering noise. To
avoid this, drive first in four-wheel
drive to warm up the vehicle and
differential gear oil. Then, shift to
two-wheel drive.

WARNING
ODo not park the vehicle over flam-
mable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
O
The transfer control lever
must be in the 2H, 4H or 4L position
and the parking brake set to prevent
the vehicle from rolling.
ONever place the transfer control le-
ver in the N (Neutral) position. Oth-
erwise, the vehicle could roll unex-pectedly even if the manual trans-
mission is in gear or the automatic
transmission is in the P (Park) posi-
tion. This could result in serious in-
jury or property damage.
OSafe parking procedures require that
both the parking brake be set and
the transmission placed into P (Park)
for automatic transmission models
or in an appropriate gear for manual
transmission models. Failure to do
so could cause the vehicle to move
unexpectedly or roll away and resultin an accident. Make sure the shift
lever has been pushed as far forward
as it can go and cannot be moved
without depressing the foot brake
pedal.
ONever leave the engine running while
the vehicle is left unattended.
O
Do not leave children unattended in-
side the vehicle. They could unknow-
ingly activate switches or controls.
Unattended children could become
involved in serious accidents.
OIf the ATP lamp is ON, this indicates
that the automatic transmission P
(park) position will not function and
the transfer control lever is in the N
(neutral) position. Failure to engage
the transfer control lever in the 2H,
4H or 4L position could result in the
vehicle moving unexpectedly, result-
ing in serious personal injury or
property damage.
1. Firmly apply the parking brake.

1st position.
Automatic transmission models:
Move the gearshift lever to the P (Park)
position.
3. To help prevent the vehicle from rolling
into the street when parked on an incline,
it is a good practice to turn the wheels as
illustrated.
O
HEADED DOWNHILL WITH CURB:s1
Turn the wheels into the curb and move
the vehicle forward until the curb side
wheel gently touches the curb.
OHEADED UPHILL WITH CURB:
s2
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
OHEADED UPHILL OR DOWNHILL, NO
CURB:
s3
Turn the wheels toward the side of the
road so the vehicle will move away from
the center of the road if it moves.
4. Turn the ignition key to the LOCK posi-
tion and remove the key.The power assisted steering is designed to
use a hydraulic pump, driven by the engine,
to assist steering.
If the engine stops or drive belt breaks, you
will still have control of the vehicle. How-
ever, much greater steering effort is needed,
especially in sharp turns and at low speeds.
WARNING
If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be much harder to operate.The brake system has two separate hydrau-
lic circuits. If one circuit malfunctions, you
will still have braking at two wheels.
BRAKING PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using
engine vacuum. If the engine stops, you can
stop the vehicle by depressing the brake
pedal. However, greater foot pressure on
the brake pedal will be required to stop the
vehicle and stopping distance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake linings and pads faster,
and reduce gas mileage.
To help reduce brake wear, and to prevent
the brakes from overheating, reduce speed
and downshift to a lower gear before going
down a slope or long grade.
POWER STEERING BRAKE SYSTEM
Starting and driving5-25
ZX

WARNING
OWhile driving on a slippery surface,
be careful when braking, accelerat-
ing or downshifting. Abrupt braking
or accelerating could cause the
wheels to skid and result in an acci-
dent.
OIf the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet. As a
result, your braking distance will be longer
and the vehicle may pull to one side during
braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal
to heat the brakes. Do this until the brakes
return to normal. Avoid driving the vehicle at
high speeds until the brakes function cor-
rectly.
ANTI-LOCK BRAKE SYSTEM (ABS)
Using the System
Depress the brake pedal and hold it down.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
Normal operation
The anti-lock brake system does not oper-
ate at speeds below 3 to 6 MPH (5 to 10
km/h). (The speeds vary according to road
conditions.)
When driving, the anti-lock brake system
controls the wheels so they will not lock
when braking abruptly or when braking on a
slippery road. Thus, difficult steering and
swerving of the vehicle due to locked
wheels is minimized. The system detects
the wheel rotation rate and electronically
controls the pressure applied to each brake.
Slight vibration on the brake pedal accom-
panied by noise usually occurs while the
ABS system is operating. Such vibration
and noise encountered during abrupt brak-ing is not a problem, but indicates that the
system is functioning.
Self-test feature
The anti-lock brake system consists of elec-
tronic sensors and hydraulic solenoids con-
trolled by a computer. The computer has a
built-in diagnostic feature that tests the sys-
tem each time you start the engine and
move the vehicle at a low speed in forward
or reverse. When the self-test occurs, you
may hear a ``clunk'' noise and/or feel a
pulsation in the brake pedal. This is normal
and is not an indication of any malfunction. If
the computer senses any malfunction, it
switches the anti-lock brake system off and
turns on the ABS brake warning light in the
dashboard. The brake system then operates
normally, but without anti-lock assistance.
If an abnormality occurs in the system, the
anti-lock function will cease but the ordinary
brakes will continue to operate normally. The
ABS brake warning light will then come on.
If the light comes on while you are driving,
contact an authorized NISSAN dealer for
repair.

WARNING
OThe anti-lock brake system is a
sophisticated device, but it cannot
prevent accidents resulting from
careless or dangerous driving tech-
niques. It can help maintain vehicle
control under braking on slippery
surfaces, but remember that the
stopping distance on slippery sur-
faces will be longer than on normal
surfaces even with the anti-lock
brake system. Stopping distances
may also be longer on rough, gravel,
or snow covered roads, or if you are
using tire chains. Always maintain a
safe distance from the vehicle in
front of you. Ultimately, the respon-
sibility for safety of self and others
rests in the hands of the driver.
Tire type and condition may also affect
braking effectiveness.
OWhen replacing tires, install the
specified tire size on all four wheels.
OWhen installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. For tireplacard location information refer to
``Tire placard'' in the ``Technical and
consumer information'' section of
this manual.FREEING A FROZEN DOOR
LOCK
To prevent a door lock from freezing, apply
de-icer or glycerin through the key hole. If
the lock becomes frozen, heat the key be-
fore inserting it in the key hole.
ANTI-FREEZE
In the winter when it is anticipated that the
temperature will drop below 32ÉF (0ÉC),
check anti-freeze (ethylene glycol base) to
assure proper winter protection. For details,
see ``Engine cooling system'' in the ``Main-
tenance and do-it-yourself'' section of this
manual.
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the bat-
tery fluid may freeze and damage the bat-
tery. To maintain maximum efficiency, the
battery should be checked regularly. For
details, see ``Battery'' in the ``Maintenance
and do-it-yourself'' section of this manual.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
anti-freeze, drain the cooling system by open-

ing the drain valves located under the radiator
and on the engine block. Refill before operat-
ing the vehicle. For details, see ``Changing
engine coolant'' in the ``Maintenance and
do-it-yourself'' section of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to
provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate your vehicle on snowy or icy roads,
NISSAN recommends the use on all four
wheels of MUD & SNOW or ALL SEA-
SON tires. Please consult your NISSAN
dealer for the tire type, size, speed rating
and availability information.
2. For additional traction on icy roads, stud-
ded tires may be used. However, some
U.S. states and Canadian provinces pro-
hibit their use. Check local, state and pro-
vincial laws before installing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow
tires.
3. Tire chains may be used. Use of tirechains may be prohibited according to
location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are of proper size
for the tires on your vehicle and are
installed according to the chain manufac-
turer's suggestions.Use only SAE
Class ``S'' chains.Other types may
damage your vehicle. Use chain tension-
ers when recommended by the tire chain
manufacturer to ensure a tight fit. Loose
end links of the tire chain must be se-
cured or removed to prevent the possi-
bility of whipping action damage to the
fenders or undercarriage. If possible,
avoid fully loading your vehicle when
using tire chains. In addition, drive at a
reduced speed, otherwise, your vehicle
may be damaged and/or vehicle handling
and performance may be adversely af-
fected. Never install tire chains on a
TEMPORARY USE ONLY spare tire. Do
not use tire chains on dry roads.SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
1. A scraper and stiff-bristled brush to re-move ice and snow from the windows
and wiper blades.
2. A sturdy, flat board to be placed under
the jack to give it firm support.
3. A shovel to dig the vehicle out of snow-
drifts.
4. Extra window washer fluid to refill the
reservoir tank.
DRIVING ON SNOW OR ICE
WARNING
OWet ice (32ÉF, 0ÉC and freezing rain),
very cold snow, or ice can be slick
and very hard to drive on. The ve-
hicle will have much less traction or
``grip'' under these conditions. Try to
avoid driving on wet ice until the
road is salted or sanded.
OWhatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shifting too fast, the drive wheels
will lose even more traction.
O
Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
OAllow greater following distances on
slippery roads.
5-28Starting and driving
ZX

OWatch for slippery spots (glare ice).
These may appear on an otherwise
clear road in shaded areas. If a patch
of ice is seen ahead, brake before
reaching it. Try not to brake while on
the ice, and avoid any sudden steer-
ing maneuvers.
ODo not use the cruise control on
slippery roads.
OSnow can trap dangerous exhaust
gases under your vehicle. Keep
snow clear of the exhaust pipe and
from around your vehicle.
ENGINE BLOCK HEATER (if so
equipped)
An engine block heater to assist extreme
cold temperature starting is available
through an authorized NISSAN dealer.
WARNING
Do not use your heater with an un-
grounded electrical system or two-
pronged (cheater) adapters. You can be
injured by an electrical shock if you use
an ungrounded connection.

sion into R (Reverse), or the automatic
transmission into P (Park).
WARNING
O
The transfer control lever
must be in the 2H, 4H or 4L position.
O
Do not leave the transfer control le-
ver in the N (Neutral) position. Other-
wise, the vehicle could roll unexpect-
edly even if the manual transmission
is in any gear or the automatic trans-
mission is in the P (Park) position.
This could result in serious personal
injury or property damage.

jack.
ONever use the tool tray as a jacking
surface.
ODo not allow passengers to stay in
the vehicle while it is on the jack.
ODo not start or run engine while
vehicle is on the jack. It may cause
the vehicle to move. This is espe-
cially true for vehicles with limited
slip differential carriers.
WARNING
OIncorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
ODo not use oil or grease on the wheel
studs or nuts. This could cause the
nuts to become loose.
Installing the spare tire
1. Clean any mud or dirt from the surface
between the wheel and hub.
2. Carefully put the spare tire on and tighten
the wheel nuts finger tight.
3. With the wheel nut wrench, tighten the
wheel nuts alternately and evenly until
they are tight.
4. Lower the vehicle slowly until the tire
touches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts se-
curely in the sequence as illustrated.
Lower the vehicle completely.
As soon as possible, tighten the wheel
nuts to the specified torque with a torque
wrench.
Wheel nut tightening torque:
98 ft-lb (133 Nzm)
The wheel nuts must be kept tightened to
specification at all times. It is recom-
mended that wheel nuts be tightened to
specification at each lubrication interval.
Adjust tire pressure to the COLD pres-

ORetighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
5. Securely store the flat tire and jacking
equipment in the vehicle.
WARNING
Always make sure that the spare tire
and jacking equipment are properly se-
cured after use. Such items can be-
come dangerous projectiles in an acci-
dent or sudden stop.To start your engine with a booster battery,
the instructions and precautions below must
be followed.
WARNING
OIf done incorrectly, jump starting can
lead to a battery explosion, resulting
in severe injury or death. It could
also damage your vehicle.
OExplosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away
from the battery.
ODo not allow battery fluid to come
into contact with eyes, skin, clothing
or painted surfaces. Battery fluid is a
corrosive sulphuric acid solution
which can cause severe burns. If the
fluid should come into contact with
anything, immediately flush the con-
tacted area with water.
OKeep battery out of the reach of
children.
OThe booster battery must be rated at
12 volts. Use of an improperly rated
battery can damage your vehicle.OYour vehicle has and automatic en-
gine cooling fan. It could come on at
any time. Keep hands and other ob-
jects away from it.
OWhenever working on or near a bat-
tery, always wear suitable eye pro-
tectors (for example, goggles or in-
dustrial safety spectacles) and
remove rings, metal bands, or any
other jewelry. Do not lean over the
battery when jump starting.
ODo not attempt to jump start a frozen
battery. It could explode and cause
serious injury.
WARNING
Always follow the instructions be-
low. Failure to do so could result in
damage to the charging system and
cause personal injury.
