lock NISSAN FRONTIER 1996 D22 / 1.G Owner's Guide

Your NISSAN is equipped with one of two
4WD systems, auto-lock free-running hubs
or manual-lock free-running hubs.
The auto-lock free-running hub is designed
to allow for automatic 4-wheel drive en-
gagement when the shift lever is moved to
the 4H or 4L position. If your vehicle is
equipped with this system, follow these op-
erational cautions:
CAUTION
cThe auto-locking hubs will make a
clicking noise when engaging and
disengaging. This is normal.cSudden acceleration from a stop af-
ter shifting from 2-wheel drive to
4-wheel drive may not allow engage-
ment 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.
cIf the auto-locking hubs make a clat-
tering noise after shifting from
4-wheel drive to 2-wheel drive, stop
and move the vehicle about 7 to 10
feet (2 to 3 m) in reverse.
cUnder 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 4-wheel drive
to warm up the vehicle and differen-
tial gear oil. Then, shift to 2-wheel
drive.

cIn cold weather, it may be necessary
to reduce speed or stop the vehicle
in order to shift from 2-wheel drive to
4-wheel drive.
cWhen shifting into or out of 4-wheel
drive while driving, do not stop shift
lever movement midway. An incom-
plete shift may cause a clattering
noise from the auto-locking hubs.
Continued use of the vehicle with
this noise may damage the hub lock.
Drive in 4-wheel drive to stop the
noise. Shift to 2-wheel drive as de-
scribed.

TRANSFER CASE:SHIFT PROCEDURE FOR AUTO-LOCK FREE-RUNNING HUBS
From 2H to 4HMove the transfer 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.
From 4H to 2HMove the transfer 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.
NOTE:
For 2-wheel drive operation, set the free-running hubs in the disengaged position. AUTO-LOCK hubs will not disen-
gage until the vehicle is moved about 3 feet (1 m) in the opposite direction of travel:
cWhen driving forward, stop and move 3 feet (1 m) in reverse.
cWhen backing up, stop and move 3 feet (1 m) forward, then move the vehicle about 3 feet (1 m) in reverse.
This will allow for better fuel economy, quieter ride and less component wear.
From 4H or 4L to 4L or
4H1. Stop the vehicle.

The manual-lock free-running hubs are de-
signed to allow you to engage or disengage
the front drive shaft to the front wheels.
Before driving, set the free-running hub to
the desired position:
c2-wheel operation Ð Turn the knob to
the FREE position.
c4-wheel operation Ð Turn the knob to
the LOCK position.
Be certain to align theSmark on the knob
with thecmark on the wheel hub.
CAUTION
cNever drive in 4-wheel drive (4H or
4L) with the free-running hubs in the
FREE position.
cDo not drive your vehicle with the
left and right free-running hub set to
different positions.
cFor the first 300 miles (500 km) it is
recommended that you drive in the
2H position, with the free-running
hubs set in the LOCK position.
cTo ensure proper lubrication of front
drive components, drive in the LOCK
position for at least 10 miles (16 km)
each month.

WARNING
The transfer control lever must
be in the 2H, 4H or 4L position to
prevent the vehicle from rolling.
Never place it in the N position. Other-
wise, the vehicle could roll unexpect-
edly even if the manual transmission is
in gear.
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.
cHEADED DOWNHILL WITH CURB:
s1
Turn the wheels into the curb and move
the vehicle forward until the curb side
wheel gently touches the curb.
cHEADED 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.
cHEADED 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.
CAUTION
cNever leave the engine running while
the vehicle is unattended.
cNever leave children unattended in
the vehicle.cDriving with 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 pres-
sure on the brake pedal will be required
to stop the vehicle and the stopping
distance will be longer.
cDriving with power assisted steering:
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.
However, much greater steering effort is
needed, especially in sharp turns or at
low speeds.
cWet 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 brakes, drive the vehicle at a safe
speed while lightly pressing the brake
pedal to heat-up the brakes. Do this until

the brakes return to normal. Avoid driving
the vehicle at high speeds until the
brakes function correctly.
cAvoid 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.
cTo help reduce brake wear and to pre-
vent the brakes from overheating, before
going down a slope or long grade, reduce
speed and downshift to a lower gear.
cWhile driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking actions or
sudden acceleration could cause the
wheels to skid.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 in the 2-wheel drive mode, the
rear anti-lock brake system controls the rear
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 rear wheels is mini-
mized. The system detects the rear wheel
rotation rate and electronically controls the
pressure applied to each rear brake. Slight
vibration on the brake pedal accompanied
by noise usually occurs while the ABS sys-
tem is operating. Such vibration and noise
encountered during abrupt braking is not a
problem, but indicates that the system is
functioning.
Even with the rear anti-lock brake sys-
tem, your front wheels can still lock. If
this happens, release the brake pedal
slightly and then reapply pressure.
Self-test feature
The rear anti-lock brake system consists of
an electronic sensor and two hydraulic so-lenoids controlled by a computer. The com-
puter has a built-in diagnostic feature that
tests the system 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 rear 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 rear
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 your NISSAN dealer for repair.
The rear anti-lock brake system
may only be effective when driving in the
2-wheel drive mode.
When driving in the 4-wheel drive mode, the
rear anti-lock brake system may not be
effective in many cases because the front
axle is connected with the rear axle through

the transfer gear. The rear wheels lock if the
front wheels lock. If this happens, the rear
anti-lock brake system may cease function-
ing but the ordinary brakes will continue to
operate normally. The ABS brake warning
light will then come on.
The above condition is not a malfunction
and the rear anti-lock brake system recov-
ers when the engine is started again. The
ABS brake warning light then goes off.
Using the System
Depress the brake pedal and hold it down.
It is not necessary to pump the brake pedal.
Doing so may result in increased stopping
distances.
WARNING
The rear anti-lock brake system is a
sophisticated device. But it cannot pre-
vent accidents resulting from careless
or dangerous driving techniques. It can
help maintain vehicle control under
some conditions, but remember that
the stopping distance on slippery sur-
faces will be longer than on normal
surfaces even with rear wheel ABS.Stopping distances may also be long-
eron 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 responsibility for safety of self and
others rests in the hands of the driver.
Tire type and condition may also affect
braking effectiveness.
cWhen replacing tires, install the
specified size of tires on all 4 wheels.
cWhen installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. See
``Tire placard'' in the ``Technical and
consumer information'' section.
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 into 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 ``Do-it-
yourself operations'' section.
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 ``Do-it-yourself
operations'' section.
Draining of coolant water
If the vehicle is to be left outside without
anti-freeze, drain the cooling system by
opening the drain valves located under the
radiator and on the engine block. Refill
