1999 NISSAN FRONTIER engine

During the first 1,000 miles (1,609 km),
follow these recommendations for the future
reliability and economy of your new vehicle.
Failure to follow these recommendations
may result in vehicle damage or shortened
engine life.
IDo not run the engine over 4,000 rpm.
IDo not drive over the following speed
limits:
two-wheel drive models:
55 MPH (88 km/h)
four-wheel drive models
(2H or 4H position):
55 MPH (88 km/h)
four-wheel drive models
(4L position):
30 MPH (48 km/h)
IDo not accelerate at full throttle in any
gear.
IAvoid quick starts.
IAvoid hard braking as much as possible.
IDo not tow a trailer for the first 500 miles
(805 km).IAccelerate slowly and smoothly. Maintain
cruising speeds with a constant accelera-
tor position.
IDrive at moderate speeds on the high-
way. Driving at high speeds lowers fuel
economy.
IAvoid unnecessary stopping and brak-
ing. Maintain a safe distance behind
other vehicles.
IUse a proper gear range which suits road
conditions. On level roads, shift into high
gear as soon as possible.
IAvoid unnecessary engine idling.IKeep your engine tuned up.
IFollow the recommended periodic main-
tenance schedule.
IKeep the tires inflated to the correct
pressure. Low tire pressure increases
tire wear and wastes fuel.
IKeep the front wheels in correct align-
ment. Improper alignment increases tire
wear and lowers fuel economy.
IAir conditioner operation lowers fuel
economy. Use the air conditioner only
when necessary.
IWhen cruising at highway speeds, it is
more economical to use the air condi-
tioner and leave the windows closed to
reduce drag.
I
Use 4H or 4L position only when neces-
sary. Four-wheel drive operation lowers
fuel economy.

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. If your vehicle is
equipped with this system, follow these op-
erational cautions:
CAUTION
IThe auto-locking hubs will make a
clicking noise when engaging and
disengaging. This is normal.IAccelerating 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.
IIf the auto-locking hubs make a clat-
tering noise after shifting from four-
wheel drive to two-wheel drive, stop
and move the vehicle about 7 to 10
feet (2 to 3 m) in reverse.
IUnder 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.IIn cold weather, it may be necessary
to reduce speed or stop the vehicle
in order to shift from two-wheel drive
to four-wheel drive.
IWhen shifting into or out of four-
wheel drive while driving, do not
stop shift lever movement midway.
An incomplete 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 four-wheel
drive to stop the noise. Shift to two-
wheel drive as described.

Your NISSAN is designed for both normal
and off-road use. It has a higher ground
clearance and a narrower track to make it
suitable for off-road use. These characteris-
tics give the vehicle a higher center of
gravity than ordinary passenger cars. An
advantage of the higher ground clearance is
a better view of your surroundings, allowing
you to anticipate problems. However, avoid
driving in deep water or mud as your
NISSAN is mainly designed for leisure use,
unlike a conventional off-road vehicle.
Please observe the following precautions:
WARNING
IDrive carefully when off the road and
avoid dangerous areas. Always wear
your seat belts to help keep you and
your passengers in position when
driving over rough terrain.
IDo not drive across steep slopes.
Instead drive either straight up or
straight down the slopes. Off-road
vehicles can tip over sideways much
more easily than they can forward or
backward.IMany hills are too steep for any ve-
hicle. If you drive up them, you may
stall. If you drive down them, you
may not be able to control your
speed. If you drive across them, you
may roll over.
IStay alert when driving to the top of
a hill. At the top there could be a
drop-off or other hazard that could
cause an accident.
IIf your engine stalls or you cannot
make it to the top of a steep hill,
never attempt to turn around. Your
vehicle could tip or roll over. Always
back straight down in reverse gear.
Never back down in N (neutral) or
with the clutch depressed, using
only the brake, as this could cause
loss of control.
I
Heavy braking going down a hill could
cause your brakes to overheat and
fade, resulting in loss of control and
an accident. Apply brakes lightly and
use a low gear to control your speed.
IIf at all possible, avoid sharp turning
maneuvers, particularly at high
speeds. Your NISSAN four-wheel drive
vehicle has a higher center of gravitythan a two-wheel drive vehicle and can
tip over more easily. The vehicle is not
designed for cornering at the same
speeds as conventional two-wheel
drive vehicles any more than low-
slung sports cars are designed to per-
form satisfactorily under off-road con-
ditions. Failure to operate this vehicle
correctly could result in loss of con-
trol and/or a rollover accident.
IUnsecured cargo can be thrown
around when driving over rough ter-
rain. Properly secure it so that it will
not be thrown forward and cause
injury to you or your passengers.
IAvoid raising the center of gravity by
loading things on the roof or equip-
ping the vehicle with tires larger than
specified in this manual. This could
cause your vehicle to roll over. Put
heavy loads in the cargo area as far
forward and as low as possible.
IDo not grip the inside or spokes of
the steering wheel when driving off-
road. The steering wheel could jerk
and injure your hands. Instead drive
with your fingers and thumbs on the
outside of the rim.

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.
IHEADED DOWNHILL WITH CURB:À
1
Turn the wheels into the curb and move
the vehicle forward until the curb side
wheel gently touches the curb.
IHEADED UPHILL WITH CURB:Á
2
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
IHEADED UPHILL OR DOWNHILL, NO
CURB:Â
3
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 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 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 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.
POWER STEERING SYSTEM BRAKE SYSTEM

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
IWhile driving on a slippery surface,
be careful when braking, accelerat-
ing or downshifting. Abrupt braking
actions or sudden acceleration
could cause the wheels to skid and
result in an accident.
IIf the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.
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, youmay 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.
Using the System, 4WD Vehicles
(4 wheel ABS)
Depress the brake pedal and hold it down.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
ANTI-LOCK BRAKE SYSTEM
(ABS)
Starting and driving5-29
ZX

Using the system, 2WD Vehicles
(2 wheel rear ABS)
Depress the brake pedal and hold it down.
With the rear anti-lock brake system, the
front wheels can still lock. If this happens,
release the brake pedal slightly and then
reapply pressure.
WARNING
The anti-lock brake system is a sophis-
ticated device. But it cannot prevent
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 ABS. Stopping dis-
tances 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.
IWhen replacing tires, install the
specified size of tires on all four
wheels.
IWhen 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 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 ``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 ``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
opening the drain valves located under the
radiator and on the engine block. Refill

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
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. Use of tire
chains may be prohibited according tolocation. 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
IWet 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 a lot less traction or
``grip'' under these conditions. Try to
avoid driving on wet ice until the
road is salted or sanded.
IWhatever 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.
I
Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
IAllow greater following distances on
slippery roads.

IWatch 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
actually on the ice, and avoid any
sudden steering maneuvers.
IDo not use the cruise control on
slippery roads.
ISnow 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.
