THREE-WAY CATALYST
The three-way catalyst is an emission control
device, installed in the exhaust system. In the
converter, exhaust gases are burned at high
temperatures to help reduce pollutants.
IThe exhaust gas and the exhaust sys-
tem are very hot. While the engine is
running, keep people or flammable
materials away from the exhaust sys-
tem.
IDo not stop or park the vehicle over
flammable materials, such as dry
grass, waste paper, or rags as they
may burn easily.
To help prevent damage
IDo not use leaded gasoline.
Deposits from leaded gasoline will seri-
ously reduce the three-way catalyst's
ability to help reduce exhaust pollut-
ants.
IKeep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, orelectrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if noticeable
loss of performance or other unusual
operating conditions are detected. Have
the vehicle inspected promptly by an
authorized NISSAN dealer.
IAvoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
IDo not race the engine while warming it
up.
IDo not push or tow your vehicle to start
the engine.Utility vehicles have higher ground clearance
than passenger cars and a narrower track to
make them capable of performing in a wide
variety of off-road applications. Specific design
characteristics give them a higher center of
gravity than ordinary cars. An advantage of
higher ground clearance is a better view of the
road, allowing you to anticipate problems.
They are not designed for cornering at the
same speeds as conventional 2-wheel drive
vehicles any more than low-slung sports cars
are designed to perform satisfactorily under
off-road conditions. If at all possible, avoid
sharp turns or abrupt maneuvers. As with
other vehicles of this type, failure to operate
this vehicle correctly may result in loss of
control or vehicle rollover.
Be sure to read the driving safety precautions
later in this section.
ON-PAVEMENT AND OFF-ROAD
DRIVING PRECAUTIONS
4-3
Z01.2.1/R50-DX
When replacing a tire, use the same size and
load carrying capacity as originally equipped.
Recommended types and sizes are shown in
ªwheels and tiresº in the ªTechnical informa-
tionº section. 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 ad-
versely affect the ride, braking, handling,
ground clearance, body- to-tire clearance,
snow chain clearance, speedometer calibra-
tion, headlight aim and bumper height. Some
of these effects may lead to accidents and
could result in serious personal injury.
Changing tires and wheels
When replacing a tire, use the same size,
speed rating and load carrying capacity as
originally equipped. Recommended types and
sizes are shown in ªWheels and tiresº in the
ªTechnical informationº section. The use of
tires other than those recommended or the
mixed use of tires of different brands, con-
struction (bias, bias-belted or radial), or tread
patterns can adversely affect the ride, braking,
handling, ground clearance, body-to-tire clear-
ance, snow chain clearance, speedometer
calibration, headlight aim and bumper height.
Some of these effects may lead to acci-
dents and could result in serious personal
injury.If the wheels are changed for any reason,
always replace with wheels which have the
same offset dimension. Wheels of a different
offset could cause early tire wear, possibly
degraded vehicle 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.
Do 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 warning.
4-WHEEL DRIVE MODELS
Always use tires of the same size, brand,
construction (bias, bias-belted or ra-
dial), 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 dam-age 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 cor-
rected as necessary. Contact your NISSAN
dealer.
ONLY use spare tires specified for each
4-wheel drive model.
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 balancing
the front wheels on the vehicle could lead to
transmission damage.
