1997 NISSAN FRONTIER lock

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.

Automatic transmission models:
Move the gearshift lever to the P (Park)
position.
WARNING
Safe parking procedures require that
both the parking brake be set and the
transmission placed into P position
(automatic) or in the appropriate gear
(manual). Failure to do so could cause
the vehicle to move unexpectedly or
roll away and result in an accident.
Make sure the gear lever has been
pushed as far forward as it can go and
cannot be moved without depressing
the button at the end of the lever.
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.
WARNING
cNever leave children unattended in
the vehicle.
cNever leave the engine running while
the vehicle is unattended.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 or at low
speeds.
POWER STEERING SYSTEM
4-24
ZX

The brake system has two separate hydrau-
lic circuits. If one circuit develops a problem,
you will still have braking at two wheels.
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 the stopping distance will be
longer.
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 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.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.
WARNING
While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking actions
or sudden acceleration could cause the
wheels to skid and result in an acci-
dent.
Normal Operation
The rear anti-lock brake system does not
operate 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 throughthe 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.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
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 undersome 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 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 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 four
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. Refillbefore operating the vehicle. For details,
see ``Changing engine coolant'' in the ``Do-
it-yourself operations'' section.
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
provinces and states prohibit their use.
Check local, state and provincial 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 if desired. Use
of tire chains may be prohibited accord-
ing to location. Check the local lawsbefore installing tire chains. When install-
ing tire chains, make sure they are of
proper size for the tires on your vehicle
and are installed according to the chain
manufacturer's suggestions.Use only
SAE Class ``S'' chains.Other types
may damage your vehicle. Use chain
tensioners when recommended by the
tire chain manufacturer to ensure a tight
fit. Loose end links of the tire chain must
be secured or removed to prevent the
possibility 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.
