1999 NISSAN FRONTIER service

When towing your vehicle, U.S. States, Ca-
nadian provinces and local regulations for
towing must be followed. Incorrect towing
equipment could damage your vehicle. Tow-
ing instructions are available from an autho-
rized NISSAN dealer. Local service operators
are generally familiar with the applicable laws
and procedures for towing. To assure proper
towing and to prevent accidental damage to
your vehicle, NISSAN recommends having a
service operator tow your vehicle. It is advis-
able to have the service operator carefully
read the following precautions:
WARNING
INever ride in a vehicle that is being
towed.
INever get under your vehicle after it
has been lifted by a tow truck.
CAUTION
IWhen towing, make sure that the
transmission, axles, steering system
and powertrain are in working con-
dition. If any unit is damaged, a dolly
must be used.IWhen towing with the front wheels
on the ground:
Turn the ignition key to the OFF
position and secure the steering
wheel in a straight-ahead position
with a rope or similar device. Never
place the ignition key in the LOCK
position. This will result in damage
to the steering lock mechanism.
IWhen towing with the rear wheels on
the ground:
Release the parking brake and move
the gearshift lever to the N (Neutral)
position.
On automatic transmission models,
to move the shift lever to N (Neutral),
turn the ignition key to the ACC po-
sition. After moving the shift lever to
N (neutral), be sure to turn the igni-
tion key to the OFF position.
IFor four-wheel drive models:
Set the free-running hubs to the free
position. See ``
Auto-lock free-
running hubsº or ``Manual-lock
free-running hubsº as appropriate in
the ``Starting and driving'' section.Move the transfer case shift lever

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
IPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
N (Neutral). For an automatic trans-
mission, move the shift lever to P
(Park).
IBe sure the ignition key is OFF when
performing any parts replacement or
repairs.
IIf you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts, and any other moving
parts.
IIt is advisable to remove ties and any
jewelry, such as rings, watches, etc.,
before working on your vehicle.IAlways wear eye protection when-
ever you work on your vehicle.
IIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases.
INever 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.
IKeep smoking materials, flame and
sparks away from fuel and battery.
IOn gasoline engine models with the
Multiport Fuel Injection (MFI) sys-
tem, 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
IDo not work under the hood while
the engine is hot. Turn the engine off
and wait until it cools down.INever connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion is on.
IAvoid contact with used motor oil.
Improperly disposed motor oil
and/or other vehicle fluids can hurt
the environment. Always conform to
local 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.

IImproper service for a TEMPORARY
USE ONLY spare tire may result in
serious personal injury. If it is neces-
sary to repair the TEMPORARY USE
ONLY spare tire, contact an autho-
rized NISSAN dealer.
Changing tires and wheels
When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. Recom-
mended types and sizes are shown in
``Wheel/tire size'' in the ``Technical and con-
sumer information'' section of this manual.
WARNING
I
The use of tires other than those
recommended or the mixed use of
tires of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the ride,
braking, handling, ground clearance,
body-to-tire clearance, snow chain
clearance, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to
accidents and could result in serious
personal injury.IIf the wheels are changed for any
reason, always replace with wheels
which have the same offset dimen-
sion. Wheels of a different offset
could cause early tire wear, poor ve-
hicle handling characteristics and/or
interference with the brake discs/
drums. Such interference can lead to
decreased braking efficiency and/or
early brake pad/shoe wear.
IDo not install a deformed wheel or
tire even if it has been repaired. Such
wheels or tires could have structural
damage and could fail without warn-
ing.
IThe use of retread tires is not recom-
mended.
FOUR-WHEEL DRIVE
MODELS
CAUTION
Always use tires of the same size,
brand, construction (bias, bias-belted
or radial), and tread pattern on all four
wheels. A spare tire of same size,
brand, construction and tread pattern
must also be used.Failure to do so may result in a circum-
ference difference between tires on the
front and rear axles which will cause
excessive tire wear and may damage
the transmission, transfer case and dif-
ferential gears.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked
and corrected as necessary. Contact an
authorized NISSAN dealer.
Wheel balance
Unbalanced wheels may affect vehicle han-
dling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
Wheel balance service should be performed
with the wheels off the vehicle. Spin balanc-
ing the front wheels on the vehicle could
lead to transmission damage.
Care of wheels
IWash the wheels when washing the ve-
hicle to maintain their appearance.

Your new NISSAN has been designed to
have minimum maintenance requirements
with longer service intervals to save you
both time and money. However, some day-
to-day and regular maintenance is essential
to maintain your NISSAN's good mechani-
cal condition, as well as its emission and
engine performance.
It is the owner's responsibility to make sure
that the specified maintenance, as well as
general maintenance, is performed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
proper maintenance. You are a vital link in
the maintenance chain.
General maintenance
General maintenance includes those items
which should be checked during normal
day-to-day operation of the vehicle. They
are essential if your vehicle is to continue to
operate properly. It is your responsibility to
perform these maintenance procedures
regularly as prescribed.
These checks or inspections can be done
by yourself, a qualified technician or, if you
prefer, an authorized NISSAN dealer.
Periodic maintenance
The maintenance items listed under peri-
odic maintenance in this section are re-
quired to be serviced at regular intervals.
However, under severe driving conditions,
additional or more frequent maintenance
will be required.
Where to go for service
If maintenance service is required or your
vehicle appears to malfunction, have the
systems checked and tuned by an autho-
rized NISSAN dealer.
NISSAN technicians are well-trained spe-
cialists who and are kept up to date with the
latest service information through technical
bulletins, service tips, and in-dealership
training programs. They are completely
qualified to work on NISSAN vehicles
beforethey work on your vehicle, rather
than after they have worked on it.
You can be confident that an authorized
NISSAN dealer's service department per-
forms the best job to meet the maintenance
requirements on your vehicle Ð in a reliable
and economic way.During the normal day-to-day operation of
the vehicle, general maintenance should be
performed regularly as prescribed in this
section. If you detect any unusual sounds,
vibrations or smells, be sure to check for the
cause or have an authorized NISSAN
dealer do it promptly. In addition, you should
notify an authorized NISSAN dealer if you
think that repairs are required.
When performing any checks or mainte-
nance work, closely observe the precau-
tions in the ``Do-it-yourself'' section of this
manual.
OUTSIDE THE VEHICLE
The maintenance items listed here should
be performed from time to time, unless
otherwise specified.
Additional information on the following
items with ``*'' is found in the ``Do-it-
yourself'' section of this manual.

GENERAL MAINTENANCE
9-2Maintenance
ZX

To ensure smooth, trouble-free, safe and
economical driving, NISSAN provides two
periodic maintenance schedules that may
be used, depending upon the conditions in
which you usually drive. These schedules
contain both distance and time intervals, up
to 60,000 miles (96,000 km)/48 months. For
most people, the odometer reading will in-
dicate when service is needed. However, if
you drive very little, your vehicle should be
serviced at the regular time intervals shown
in the schedule.
After 60,000 miles (96,000 km)/48
months, continue periodic maintenance
at the same mileage/time intervals.
SCHEDULE ONE
Follow Periodic Maintenance Schedule one
if your driving habits frequently include one
or more of the following driving conditions:
I
Repeated short trips of less than 5
miles (8 km).
I
Repeated short trips of less than 10
miles (16 km) with outside tempera-
tures below freezing.
I
Operating the vehicle in hot weatherduring stop-and-go ``rush hour'' traf-
fic.
I
Extensive idling and/or low speed
driving for long distances, such as
police, taxi or door-to-door delivery
use.
I
Driving in dusty conditions.
I
Driving on rough, muddy, or salt
spread roads.
I
Towing a trailer, using a camper or a
car-top carrier.
SCHEDULE TWO
Follow Periodic Maintenance Schedule two
if none of the driving conditions shown in
Schedule one apply to your driving habits.
Maintenance for off-road driving
(
only)
Whenever you drive off-road through sand,
mud or water as deep as the wheel hub,
more frequent maintenance may be re-
quired of the following items:
¶Brake pads and rotors
¶Brake linings and drums
¶Brake lines and hoses
¶Wheel bearing grease and free-running
hub grease
¶Differential, transmission and transfer oil
¶Steering linkage
¶Propeller shafts and front drive shafts
¶Air cleaner filter
These items should be checked frequently
to assure safe and proper operation of your
vehicle.

FUEL RECOMMENDATION
Your vehicle is designed to operate on
unleaded gasoline with an octane rating
of at least 87 AKI (Anti-Knock Index)
(Research octane number 91).
CAUTION
IUsing a fuel other than that specified
could adversely affect the emission
control devices and systems, and
could also affect the warranty cover-
age.
IUnder no circumstances should a
leaded gasoline be used, since this
will damage the three-way catalyst.
Reformulated Gasoline
Some fuel suppliers are now producing re-
formulated gasolines. These gasolines are
specially designed to reduce vehicle emis-
sions. NISSAN supports efforts towards
cleaner air and suggests that you use refor-
mulated gasoline when available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE andmethanol with or without advertising their
presence. Nissan does not recommend the
use of fuels of which the oxygenate content
and the fuel compatibility for your NISSAN
cannot be readily determined. If in doubt,
ask your service station manager.
If you use oxygenate-blend gasoline, please
take the following precautions as the usage
of such fuels may cause vehicle perfor-
mance problems and/or fuel system dam-
age.
IThe fuel should be unleaded and
have an octane rating no lower than
that recommended for unleaded
gasoline.
IIf an oxygenate-blend, excepting a
methanol blend, is used, it should
contain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)
I
If a methanol blend is used, it should
contain no more than 5% methanol
(methyl alcohol, wood alcohol). It
should also contain a suitable
amount of appropriate cosolvents
and corrosion inhibitors. If not prop-
erly formulated with appropriate co-solvents and corrosion inhibitors,
such methanol blends may cause fuel
system damage and/or vehicle perfor-
mance problems. At this time, suffi-
cient data is not available to ensure
that all methanol blends are suitable
for use in NISSAN vehicles.
If any driveability problems such as engine
stalling and hard hot starting are experi-
enced after using oxygenate-blend fuels,
immediately change to a non-oxygenate
fuel or a fuel with a low blend of MTBE.
Take care not to spill gasoline during
refueling. Gasoline containing oxygen-
ates can cause paint damage.
After Market Fuel Additives
NISSAN does not recommend the use of
any fuel additives (i.e., fuel injector cleaner,
octane booster, intake valve deposit remov-
ers, etc.) which are sold commercially. Many
of these additives intended for gum, varnish
or deposit removal may contain active sol-
vents or similar ingredients that can be
harmful to the fuel system and engine.
