1999 NISSAN FRONTIER warning

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.

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.
Do-it-yourself
8-35
ZX

IClean the inner side of the wheels when
the wheel is changed or the underside of
the vehicle is washed.
IDo not use abrasive cleaners when
washing the wheels.
IInspect wheel rims regularly for dents or
corrosion. This may cause loss of pres-
sure or damage the tire bead.
INISSAN recommends waxing the road
wheels to protect against road salt in
areas where it is used during winter.
Spare tire
Your vehicle may be equipped with a TEM-
PORARY USE ONLY spare tire.
To avoid property damage or personal injury
when using the TEMPORARY USE ONLY
spare tire, observe the following cautions:
WARNING
IThe spare tire should be used for
emergency use only. It should be
replaced by the standard tire at the
first opportunity to avoid possible
tire or differential damage.IDrive carefully while the TEMPO-
RARY USE ONLY spare tire is in-
stalled. Avoid sharp turns and
abrupt braking while driving.
IPeriodically check spare tire infla-
tion pressure. Always keep the pres-
sure of the T135/70R16 spare tire at
60 psi (420 kPa, 4.2 bar). For the full
size spare tire pressure, check the
tire placecard located on the inside
of the glovebox lid.
IDo not drive the vehicle at speeds
faster than 50 MPH (80 km/h).
I
When driving on roads covered with
snow or ice, the TEMPORARY USE
ONLY spare tire should be used on
the front wheels and the original tire
used on the rear wheels (drive
wheels). Use tire chains only on the
two rear original tires.
ITire tread of the TEMPORARY USE
ONLY spare tire will wear at a faster
rate than the standard tire. Replace
the TEMPORARY USE ONLY spare
tire as soon as the tread wear indi-
cators appear.IDo not use the TEMPORARY USE
ONLY spare tire on other vehicles.
IDo not use more than one TEMPO-
RARY USE ONLY spare tire at the
same time.
IDo not tow a trailer when the TEM-
PORARY USE ONLY T135/70R16
spare is installed.
CAUTION
I
The transfer control lever must
be in the 2H position to prevent the
transfer case and differential gears
from being damaged.
IDo not use tire chains on a TEMPO-
RARY USE ONLY spare tire. Tire
chains will not fit properly on a TEM-
PORARY USE ONLY spare tire and
may cause damage to the vehicle.
I
Because the TEMPORARY USE ONLY
spare tire is smaller than the original
tire, ground clearance is reduced. To
avoid damage to the vehicle, do not
drive over obstacles. Also, do not
drive the vehicle through an automatic
car wash since it might get caught.

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
when performing periodic maintenance,
cleaning the vehicle, etc.
Additional information on the following
items with an ``*'' is found in the ``Do-it-
yourself'' section of this manual.

the wipers and washer operate properly and
that the wipers do not streak.
Windshield defrosterCheck that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating the
heater or air conditioner.
Steering wheelCheck for changes in the
steering conditions, such as excessive free-
play, hard steering or strange noises.SeatsCheck seat position controls such as
seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and all
latches lock securely in every position.
Check that the head restraints move up and
down smoothly and the locks (if so
equipped) hold securely in all latched posi-
tions.
Seat beltsCheck that all parts of the seat
belt system (e.g., buckles, anchors, adjust-
ers and retractors) operate properly and
smoothly, and are installed securely. Check
the belt webbing for cuts, fraying, wear or
damage.
Accelerator pedalCheck the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort.
Keep the floor mat away from the pedal.
Clutch pedal*Make sure the pedal oper-
ates smoothly and check that it has the
proper free travel.

UNDER THE HOOD AND
VEHICLE
The maintenance items listed here should
be checked periodically (e.g., each time you
check the engine oil or refuel).
Additional information on the following
items with an ``*'' is found in the ``Do-it-
yourself operations'' section.
Windshield washer fluid*Check that there
is adequate fluid in the reservoir.
Engine coolant level*Check the coolant
level when the engine is cold.Radiator and hosesCheck the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, de-
formation, rot or loose connections.
Brake and clutch fluid levels*Make sure
that the brake and clutch fluid level is be-
tween the MIN and MAX lines on the reser-
voir.
Battery*Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Engine drive belts*Make sure the drive
belts are not frayed, worn, cracked or oily.
Engine oil level*Check the level after
parking the vehicle on a level surface with
the engine off. Wait a few minutes for the oil
to drain back into the oil pan.
Power steering fluid level* and lines
Check the level when the fluid is cold, with
the engine off. Check the lines for proper
attachment, leaks, cracks, etc.
Automatic transmission fluid level*
Check the level after putting the selector
lever in P with the engine idling at operating
temperature.
Exhaust systemMake sure there are noloose supports, cracks or holes. If the sound
of the exhaust seems unusual or there is a
smell of exhaust fumes, immediately have
the exhaust system inspected by an autho-
rized NISSAN dealer. See the carbon mon-
oxide warning in the ``Starting and driving''
section of this manual.
UnderbodyThe underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances from the underbody, otherwise rust
may form on the floor pan, frame, fuel lines
and exhaust system. At the end of winter,
the underbody should be thoroughly flushed
with plain water, in those areas where mud
and dirt may have accumulated. See the
``Appearance and care'' section of this
manual.
Fluid leaksCheck under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use is
normal. If you should notice any leaks or if
gasoline fumes are evident, check for the
cause and have it corrected immediately.

fied for the vehicle.
IGAWR (Gross Axle Weight Rating) þ

for the front or rear axle.
Determining Vehicle Load Capacity
The load capacity of this vehicle is deter-
mined by weight, not by available cargo
space. For example, a luggage rack, bike
carrier, cartop carrier or similar equipment
does not increase load carrying capacity of
your vehicle.
To determine vehicle load capacity:
Vehicle weight can be determined by using
a commercial-grade scale, found at places
such as a truck stop, gravel quarry, grain
elevator, or a scrap metal recycling facility.
1) Determine the curb weight of your ve-
hicle.
2) Compare the curb weight amount to the
GVWR specified for your vehicle to de-
termine how much more weight your
vehicle can carry.
3) After loading (cargo and passengers),reweigh your vehicle to determine if ei-
ther GVWR or GAWR for your vehicle is
exceeded. If GVWR is exceeded, re-
move cargo as necessary. If either the
front or rear GAWR is exceeded, shift the
load or remove cargo as necessary.
Loading Tips
IThe GVW must not exceed GVWR or
GAWR as specified on the FMVSS Cer-
tification Label.
IDo not load the front and rear axle to the
GAWR. Doing so will exceed the GVWR.
ILoads should be spread out, and cargo
should be properly secured. Large or
heavy objects should be placed toward
the front of the trunk box to help prevent
sliding or shifting.
SECURING THE LOAD
For your convenience, tie down hooks are
placed at each corner of the truck box.
These may be used to help secure cargo
loaded into the truck box.
WARNING
IProperly secure all cargo with ropes
or straps to help prevent it from
sliding or shifting. In a sudden stop
or collision, unsecured cargo could
cause personal injury.

WARNING
Improper loading may be dangerous. If
a load is too far back, it can affect
handling characteristics. If a load is too
far forward, the front axle may be over-
loaded.
When the truck is used to carry a slide-in
camper, the total cargo load of the truck
consists of the camper manufacturer's
weight figure, plus:
Ithe weight of installed additional camper
equipment not included in the camper
manufacturer's weight figure,
Ithe weight of camper cargo,
Iand the weight of occupants in the
camper.
The total cargo load should not exceed the
truck's cargo weight rating and the camper's
center of gravity should fall within the truck'srecommended center of gravity location
zone when installed.
WARNING
Overloading or improper loading can
adversely affect vehicle handling, brak-
ing and performance and may lead to
accidents.

Your new vehicle was designed to be used
primarily to carry passengers and cargo.
Remember that towing a trailer will place
additional loads on your vehicle's engine,
drive train, steering, braking and other sys-
tems.
ANissan Trailer Towing Guideis available
from an authorized NISSAN dealer. This
guide includes information on trailer towing
ability and the special equipment required
for proper towing.
Maximum load limits
Maximum trailer loads
Never allow the total trailer load to exceed
the value specified in the following Towing
Load/Specification Chart. The total trailer
load equals trailer weight plus its cargo
weight.
IWhen towing a trailer load of 1,000 lb
(454 kg) or more, trailers with a brake
system MUST be used.
The maximum GCWR (Gross Combined
Weight Rating) should not exceed the value
specified in the following Towing Load/
Specification Chart.
The GCWR equals the combined weight of
the towing vehicle (including passengers
and cargo) plus the total trailer load. Towing
loads greater than these or using improper
towing equipment could adversely affect
vehicle handling, braking and performance.
WARNING
Vehicle damage and/or personal injury
resulting from improper towing proce-
dures is not covered by NISSAN war-ranties. Information on trailer towing
and required towing equipment should
be obtained from dealers who special-
ize in providing trailers or other towing
equipment.
Tongue load
Keep the tongue load between 9 to 11
percent of the total trailer load within the
maximum tongue load limits shown in the
following Towing Load/Specification Chart.
If the tongue load becomes excessive, re-
arrange cargo to allow for proper tongue
load.
