2000 NISSAN FRONTIER four wheel drive

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.

CAUTION
Always use tires of the same type, 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 an
authorized 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.
Tire inflation pressure
Periodically check the pressure in all tires,
including the spare, with a gauge. Adjust to
the specified pressure if necessary. Tirepressures are shown on the tire placard
affixed to the glove box.
Tire chain
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not drive with tire chains on paved roads
which are clear of snow. Driving with chains
in such conditions can cause damage to the
various mechanisms of the vehicle due to
some overstress. When driving on clear
paved roads, be sure to change to 2WD.

Using the system (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 during
braking on slippery surfaces, but re-
member that the stopping distance on
slippery surfaces will be longer than on
normal surfaces even with the anti-lock
brake system. Stopping distances may
also be longer on rough, gravel, or
snow covered roads, or if you are using
tire chains. Always maintain a safe dis-
tance 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. For tire
placard location information, refer to
``Tire placard'' in the ``Technical and
consumer information'' section of
this manual.
For additional information, refer to²Wheels
and Tires²in the²Do-it-yourself²section of
this manual.
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

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 much 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.

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, dollies
must be used.IWhen towing with the front wheels
on the ground or with the rear
wheels on the ground (if you do not
use towing dollies): Move the trans-
fer control shift lever into the 2H
position.
IWhen towing with the front wheels
on the ground: Turn the ignition key
to the OFF position and move the
transmission shift lever to the N
(Neutral) position. To move the se-
lector lever to the N (Neutral) posi-
tion on automatic transmission mod-
els, turn the ignition key to the ACC
position. After moving the sleector
lever to the N (Neutral) position, turn
the ignition key to the OFF position
and secure the steering wheel in the
straight ahead position with a rope
or similiar device. Never place the
ignition key in the LOCK position.
This will result in damage to the
steering lock mechanism.
IWhen towing manual transmission
models with rear wheels on the
ground: Always release the parkingbrake and move the transmission
shift lever to the N (Neutral) 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
into the 2H position and the trans-
mission shift lever into the N (Neu-
tral) position.
IAlways attach safety chains before
towing.
