1999 NISSAN FRONTIER 4WD

CAUTION
IDo not drive on dry hard surface
roads in four-wheel drive.IDriving 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
IWhen parking the vehicle, apply the
parking brake and always make sure
to shift the transfer control lever into
the 2H, 4H or 4L position.
IDo not leave the transfer control le-
ver in the N (Neutral) position. Oth-
erwise, the vehicle could roll unex-
pectedly even if the manual
transmission is in gear or the auto-
matic transmission is in the P (Park)
position.
IFailure to engage the transfer con-
trol lever in 2H, 4H, or 4L could result
in the vehicle moving unexpectedly,
which in turn could result in serious
personal injury or property damage.
2HÐ (2WD, high range) Only the rear
wheels are driven. Use when driving underthe 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 provides
maximum power and traction. Avoid raising
vehicle speed excessively, as the maximum
speed is approximately 30 MPH (48 km/h).
NÐ No wheels are driven. Always keep the
transfer lever out of the N (Neutral) position.
Shift the lever quickly and smoothly when
moving across the N (Neutral) position with
the vehicle stopped.
Your NISSAN is equipped with one of two
4WD systems, auto-lock free-running hubs
or manual-lock free-running hubs.ASD1022

IBefore operating the vehicle, ensure
that the driver and all passengers
have their seat belts fastened.
IAlways drive with the floor mats in
place as the floor may become very
hot. Particular care should be taken
if you are barefoot.
ILower 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.
IDo not drive beyond the perfor-
mance of the tires even with 4WD.
IAccelerating quickly, steering or
braking may cause loss of control.
IInstall the same size of winter tires
on all four (four) wheels (such as
studless tires) or install tire chains
to the rear wheels when driving on
slippery roads (e.g., after a snow)
and drive carefully using 4WD.
IBe sure to check the brakes immedi-
ately after driving in mud or water asspecified in ``Wet brakes'' under the
heading ``Brake system,'' later in this
section.
IAvoid 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.
IWhenever 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''
section of this manual.
Checking water entry
If you have driven in deep water or mud,
check water entry in the clutch housing by
removing the blind plug at the bottom of the
transmission case. After checking, be sure
to reinstall the plug.

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.

Tire rotation
NISSAN recommends rotating the tires ev-
ery 7,500 miles (12,000 km) for 2WD ve-
hicles and every 3,750 miles (6,000 km) for
4WD vehicles.
See ``Flat tire'' in the ``In case of emergency''
section for tire replacing procedures.
Wheel nut tightening torque:
87 to 108 ft-lb (118 to 147 N×m)
WARNING
IAfter rotating the tires, adjust the tire
pressure.
IRetighten the wheel nuts after the
wheels have been run for the first
600 miles (1,000 km) (also in cases of
a flat tire, etc.).
IDo not include the TEMPORARY
USE ONLY spare tire in the tire rota-
tion.
Tire wear and damage
WARNING
ITires should be periodically in-
spected for wear, cracking, bulging
or objects caught in the tread. If
excessive wear, cracks, bulging or
deep cuts are found, the tire should
be replaced.
IThe original tires have a built-in
tread wear indicator. When the wear
indicator is visible, the tire should be
replaced.

sure no wheel nuts are missing, and check for
any loose wheel nuts. Tighten if necessary.
Tire rotation*Tires should be rotated every
7,500 miles (12,000 km) for 2WD vehicles
and 3,750 miles (6,000 km) for 4WD ve-
hicles.
Wheel alignment and balanceIf the ve-
hicle should pull to either side while driving
on a straight and level road, or if you detect
uneven or abnormal tire wear, there may be
a need for wheel alignment.
If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing
may be needed.
Windshield wiper blades*Check for
cracks or wear if they do not wipe properly.
Doors and hoodCheck that all doors and
the hood operate properly. Also ensure that
all latches lock securely. Lubricate hinges,
latches, rollers and links if necessary. Make
sure that the secondary latch keeps the
hood from opening when the primary latch
is released.
When driving in areas using road salt or
other corrosive materials, check lubrication
frequently.Lights*Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.
INSIDE THE VEHICLE
The maintenance items listed here should
be checked on a regular basis, such as

Secure loose items to prevent weight shifts
that could affect the balance of your vehicle.
When the truck camper is loaded, drive to a
scale and weigh the front and the rear
wheels separately to determine axle loads.
Individual axle loads should not exceed
either of the gross axle weight ratings
(GAWR). The total of the axle loads should
not exceed the gross vehicle weight rating
(GVWR). These ratings are given on the
vehicle certification label that is located on
the driver's door lock pillar. If weight ratings
are exceeded, move or remove items to
bring all weights below the ratings.
