EXPLANATION OF
MAINTENANCE ITEMS
Additional information on the following
items with an ``*'' is found in the ``Do-it-
yourself'' section of this manual.
Emission control system
maintenance
Drive belts*Check drive belts for wear,
fraying or cracking and also for proper ten-
sion. Replace any damaged drive belts.
Air cleaner filterUnder normal driving con-
ditions, the air cleaner filter should be re-
placed in accordance with the maintenance
schedule. However, driving the vehicle in
dusty areas may cause rapid clogging of the
element. Consequently, the element may
have to be replaced more frequently.
Positive crankcase ventilation (PCV) fil-
terUnder normal driving conditions, the
filter should be replaced in accordance with
the maintenance schedule. If the vehicle is
operated under extremely adverse weather
conditions or in areas where ambient tem-
peratures are either extremely low or ex-
tremely high, the filter may become cloggedmore rapidly. In such an event, replace the
filter immediately.
EVAP Vapor linesCheck vapor lines and
connections for leaks, looseness, or dete-
rioration. If leaks are found, replace the
lines.
Fuel lines (hoses, piping, connections,
etc.)Check the fuel hoses, piping and con-
nections for leaks, looseness or deteriora-
tion. Replace any damaged parts.
Fuel filterIf the vehicle is operated under
extremely adverse weather conditions or in
areas where ambient temperatures are ei-
ther extremely low or extremely high, the
filter might become clogged. In such an
event, replace the filter immediately.
Engine coolant*Flush and refill the cooling
system.
Engine oil and oil filter*Under normal
driving conditions, the engine oil and oil filter
should be replaced in accordance with the
maintenance schedule. However, under se-
vere driving conditions, they may have to be
replaced more frequently.
Spark plugs*Replace with new plugs hav-
ing the correct heat range.
Chassis and body maintenance
Brake lines and cablesCheck the brake
lines and hoses (including brake booster
vacuum hoses, connections & check valve)
and parking brake cables for proper attach-
ment, leaks, cracks, chafing, abrasion, de-
terioration, etc.
Brake pads, rotors, drums and linings
Check these and the other brake compo-
nents for wear, deterioration and leaks. Un-
der severe driving conditions, they may have
to be inspected more frequently.
Manual and automatic transmission,
transfer and differential gear oilVisually
inspect for signs of leakage and replace oil
for limited-slip differential. Under severe
driving conditions, the oil should be re-
placed at the specified interval.
Steering gear (box) and linkage, axle and
suspension parts and drive shaft boots
Check for damage, looseness and leakage
of oil or grease. Under severe driving con-
ditions, they may have to be inspected more
frequently.

prevent load shift while driving.
IBe certain your outside mirrors conform
to all federal, state or local regulations. If
not, install any mirrors required for tow-
ing before driving the vehicle.
Trailer towing tips
In order to gain skill and an understanding
of the vehicle's behavior, you should prac-
tice turning, stopping and backing up in an
area which is free from traffic. Steering,
stability and braking performance will be
somewhat different than under normal driv-
ing conditions.
IAlways secure items in the trailer to
prevent load shift while driving.
I
Avoid abrupt starts, acceleration or
stops.
IAvoid sharp turns or lane changes.
IAlways drive your vehicle at a moderate
speed.
IAlways block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if
you must do so, and if your vehicle is
equipped with automatic transmission,first block the wheels and apply the
parking brake, and then move the trans-
mission shift selector lever into the P
(Park) position. If you move the shift
lever to the P (Park) position before
blocking the wheels and applying the
parking brake, transmission damage
could occur.
IWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, down-
shift the transmission to a lower gear
and reduce speed to reduce chances of
engine overloading and/or overheating.
However, for long steep grades, do not
stay in 1st or 2nd gear when driving
above 35 MPH (56 km/h).
IIf the engine coolant rises to an ex-
tremely high temperature when the air
conditioning system is on, turn off the air
conditioner. Coolant heat can be addi-
tionally vented by opening the windows,
switching the fan control to high and
setting the temperature control to the
HOT position.
ITrailer towing requires more fuel than
normal circumstances.
IAvoid towing a trailer for your vehicle'sfirst 500 miles (805 km).
IHave your vehicle serviced more often
than at intervals specified in the recom-
mended Maintenance Schedule.
IWhen making a turn, your trailer wheels
will be closer to the inside of the turn
than your vehicle wheels. To compen-
sate for this, make a larger than normal
turning radius during the turn.
ICrosswinds and rough roads adversely
affect vehicle/trailer handling, possibly
causing vehicle sway. When being
passed by larger vehicles, be prepared
for possible changes in crosswinds that
could affect vehicle handling. If swaying
does occur, firmly grip the steering
wheel, steer straight ahead, and imme-
diately (but gradually) reduce vehicle
speed. This combination helps to stabi-
lize the vehicle. Never increase speed.
IBe careful when passing other vehicles.
Passing while towing a trailer requires
considerably more distance than normal
passing. Remember the length of the
trailer must also pass the other vehicle
before you can safely change lanes.

ZX

Due to legal requirements in some states
and Canadian provinces, your vehicle may
be required to be in the ready condition for
an Inspection/Maintenance (I/M) test of the
emission control system.
The vehicle is set to the ready condition
when it is driven through certain driving
patterns. Usually, the ready condition can
be obtained by ordinary usage of the ve-
hicle.
If a powertrain system component is re-
paired or the battery is disconnected, the
vehicle may be reset to a not ready condi-
tion. Before taking the I/M test, drive the
vehicle through the following pattern to set
the vehicle to the ready condition. If you
cannot or do not want to perform the driving
pattern, an authorized NISSAN dealer can
conduct it for you.
WARNING
Always drive the vehicle in a safe man-
ner according to traffic conditions and
obey all traffic laws.1. Start the engine when the engine coolant
temperature gauge needle points to C.
Allow the engine to idle until the gauge
needle points between the C and H (nor-
mal operating temperature).
2. Accelerate the vehicle to 55 mph (88
km/h), then quickly release the accelera-
tor pedal completely and keep it released
for at least 6 seconds.
3. Quickly depress the accelerator pedal for
a moment, then drive the vehicle at a
speed of 53 to 60 mph (85 to 97 km/h) for
at least 5 minutes.
4. Stop the vehicle.
5. Accelerate the vehicle to 35 mph (55
km/h) and maintain the speed for 20
seconds.
6. Repeat steps four through five least three
times.
7. Accelerate the vehicle to 55 mph (88
km/h) and maintain the speed for at least
3 minutes.
8. Stop the vehicle and turn the engine off.
9. Repeat steps one through eight at least
one more time.
If step one through seven interrupted, repeat
the preceding step. Any safe driving mode is
acceptable between steps. Do not stop the
engine until step seven is completed.
