1997 NISSAN FRONTIER four wheel drive

cKeep your engine tuned up.
cFollow the recommended periodic main-
tenance schedule.
cKeep the tires inflated to the correct
pressure. Low pressure increases tire
wear and wastes fuel.
cKeep the front wheels in correct align-
ment. Improper alignment increases tire
wear and lowers fuel economy.
cAir conditioner operation lowers fuel
economy. Use the air conditioner only
when necessary.
cWhen cruising at highway speeds, it is
more economical to use the air condi-
tioner and leave the windows closed to
reduce drag.
c
Use 4H or 4L position only when neces-
sary. 4-wheel drive operation lowers fuel
economy.2HÐ (2WD, high range) Only the rear
wheels are driven. Use when driving under
the same conditions as standard 2WD ve-
hicle.
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 pro-
vides maximum power and traction. Avoidraising vehicle speed excessively, as the
maximum speed in 5th gear is approxi-
mately 30 MPH (48 km/h).
NÐ No wheels are driven. Always keep the
transfer lever out of the N position. Shift the
lever quickly and smoothly when moving
across the N position with the vehicle stopped.
CAUTION
cDo not drive on dry hard surface
roads in 4-wheel drive.
cDriving on dry hard surfaces in 4H or
4L may cause unnecessary noise
and tire wear. We recommend driv-
ing in the 2H position under these
conditions.
WARNING
cWhen parking the vehicle, apply the
parking brake and shift the transfer
control lever in the 2H, 4H or 4L
position.

cBefore operating the vehicle, ensure
that the driver and all passengers
have their seat belts fastened.
cAlways drive with the floor mats in
place as the floor may become very
hot. Particular care should be taken
if you are barefoot.
cLower your speed when encounter-
ing strong crosswinds. With its
higher center of gravity, your
NISSAN is more affected by gusty
side winds. Slower speeds ensure
better vehicle control.
cDo not drive beyond the perfor-
mance of the tires even with 4WD.
Accelerating quickly, steering or
braking may cause loss of control or
the vehicle to stick in the road.
cInstall the same size of winter tires
on all four (4) wheels (such as stud-
less tires) or install tire chains to the
rear wheels when driving on slippery
roads (e.g., after a snow) and drive
carefully using 4WD.
cBe sure to check the brakes immedi-
ately after driving in mud or water as
specified in ``Wet brakes'' under theheading ``Brake system,'' later in this
section.
cAvoid parking your vehicle on steep
hills. If you get out of the vehicle and
it rolls forward, backward or side-
ways, you could be injured.
cWhenever you drive off-road
through sand, mud or water as deep
as the wheel hub, more frequent
maintenance may be required. For
details, refer to ``Maintenance for off-
road driving'' in the ``Maintenance
schedule'' section.CAUTION
Always use tires of the same size,
brand, construction (bias, bias-belted
or radial), and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tires
on the front and rear axles which will
cause excessive tire wear and may
damage the transmission, transfer
case and differential 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 your
NISSAN dealer.
Snow tires
If you install snow tires, they must also be
the same size, brand, construction and
tread pattern on all four wheels.
CAUTION
ONLY use spare tires specified for each
4-wheel drive model.

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.

If you have to tow your vehicle with four
wheels on the ground or with front
wheels raised (with rear wheels on the
ground), observe the following re-
stricted towing speeds and distances:
Automatic transmission model:
cSpeed: Below 30 MPH (48 km/h)
cDistance: Less than 40 miles (64 km)
Manual transmission model:
cSpeed: Below 60 MPH (97 km/h)
cDistance: Less than 500 miles (805
km)
If the speed or distance must necessarily be
greater, remove the propeller shaft before-
hand to prevent damage to the transmis-
sion.
CAUTION
Never tow your vehicle from the rear
(i.e., backward) with four wheels on the
ground, as this may cause serious and
expensive damage to the transmission.4-WHEEL DRIVE MODELS
NISSAN recommends that a dolly be used
as illustrated when towing your vehicle.

Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front disc-type brakes self-adjust every
time the brake pedal is applied. The rear
drum-type brakes on two-wheel drive trucks
self-adjust every time the parking brake is
applied. The rear drum-type brakes on four-
wheel drive trucks self-adjust every time the
brake pedal is applied. If the brake pedal
goes down farther than normal, it may be
due to a lack of adjustment of the rear drum
brakes. Apply the parking brake several
times.
WARNING
If the brake pedal height does not re-
turn to normal, see your NISSAN dealer
and have it checked.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, it will make a high
pitched scraping or screeching sound when
the vehicle is in motion whether or not the
brake pedal is depressed. Have the brakeschecked as soon as possible if the wear
indicator sound is heard.
Under some driving or climate conditions,
occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is nor-
mal and does not affect the function or
performance of the brake system.
The rear drum brakes (if so equipped) do
not have audible wear indicators. Should
you ever hear an unusually loud noise from
the rear drum brakes, have them inspected
as soon as possible by your NISSAN
dealer.
Proper brake inspection intervals should
be followed.For more information regard-
ing brake inspections, see the appropriate
maintenance schedule information in the
``Maintenance Schedule'' section of this
manual.Check the brake booster function with the
following steps:
1. With the engine off, press and release
the brake pedal several times. When
brake pedal movement (distance of
travel) remains the same from one pedal
application to the next, continue on to
next step.
2. While depressing the brake pedal, start
the engine. The pedal height should drop
a little.
3. With the brake pedal depressed, stop the
engine. Keeping the pedal depressed for
about 30 seconds, the pedal height
should not change.
4. Run the engine for one minute without
depressing the brake pedal, then turn it
off. Depress the brake pedal several
times. The pedal travel distance will de-
crease gradually with each depression
as the vacuum is released from the
booster.
If the brakes do not operate properly, have
the brakes checked by your NISSAN dealer.

If you have a flat tire, see the ``In case of
emergency'' section.
Maximum inflation pressure
Do not exceed the maximum inflation pres-
sures shown on the side wall of the tire.
Tire inflation pressure
Periodically check the tire pressure (includ-
ing spare). Tire pressure should be checked
when tires are COLD. COLD tire pressures
are shown on the tire placard affixed to the
glove box lid.
Incorrect tire pressure may adverselyaffect tire life and vehicle handling.
COLD pressure:
After vehicle has been parked for
three hours or more or driven less
than 1 mile (1.6 km).
WARNING
cThe vehicle weight capacity is indi-
cated on the tire placard. Do not load
your vehicle beyond this capacity.
Overloading your vehicle may result
in reduced tire life, unsafe operating
conditions due to premature tire fail-
ure, or unfavorable handling charac-
teristics and could also lead to a
serious accident. Loading beyond
the specified capacity may also re-
sult in failure of other vehicle
components.
cBefore taking a long trip, or when-
ever you have loaded your vehicle
heavily, use a tire pressure gauge to
ensure that the tire pressure is at the
specified level.
cDo not drive your vehicle over 85
MPH (137 km/h) unless it is equipped
with high capability tires.Driving faster than 85 MPH (137
km/h) may result in tire failure, loss
of control and possible injury.
Types of tires
CAUTION
When changing or replacing tires, be
sure all four tires are of the same type
(i.e., Summer, All Season or Snow) and
construction. Your NISSAN dealer may
be able to help you with information
about tire type, size, speed rating and
availability. Replacement tires may
have a lower speed rating than the
factory equipped tires, and may not
match the potential maximum vehicle
speed. Never exceed the maximum
speed rating of the tire.
All season tires
NISSAN specifies All Season tires on some
models to provide good performance for
use all year around, including snowy and icy
road conditions. All Season Tires are iden-
tified by ``ALL SEASON'' and/or ``M&S'' on
the tire sidewall. Snow tires have better
DI0047
WHEELS AND TIRES

ZX

snow traction than All Season tires and may
be more appropriate in some areas.
Summer tires
NISSAN specifies summer tires on some
models to provide superior performance on
dry roads. Summer tire performance in
snow and ice will be substantially reduced.
Summer tires do not have the tire traction
rating ``M&S'' on the tire sidewall.
If you plan to operate your vehicle in snowy
or icy conditions, NISSAN recommends the
use of ``SNOW'' or ``ALL SEASON'' tires on
all four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rating
to the original equipment tires. If you do not,
it can adversely affect the safety and han-
dling of your vehicle.
Generally, snow tires will have lower speed
ratings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed the maximum speed
rating of the tire.
For additional traction on icy roads, studded
tires may be used. However, some prov-inces and states prohibit their use. Check
local, state and provincial laws before in-
stalling studded tires. Skid and traction ca-
pabilities of studded snow tires on wet or dry
surfaces may be poorer than that of non-
studded snow tires.
4-wheel drive model
If you install snow tires, they must be the
same size, brand, construction and tread
pattern on all four wheels.
CAUTION
ONLY use spare tires specified for each
4-wheel drive model.
Tire chains
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are the proper size
for the tires on your vehicle and are installed
according to the chain manufacturer's sug-
gestions.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 besecured or removed to prevent the possibil-
ity 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. Oth-
erwise, your vehicle may be damaged
and/or vehicle handling and performance
may be adversely affected.
Never install tire chains on a TEMPORARY
USE ONLY spare tire.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not use tire chains on dry roads. Driving
with chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress. When driv-
ing on clear paved roads, be sure to change
to 2WD.
