cAiming is not necessary after replac-
ing the bulb.
cDo not leave the bulb out of the
headlight reflector for a long period
of time as dust, moisture, and smoke
may enter the headlight body and
affect the performance of the head-
light.
Before adjusting the headlights, make sure
all of the tires are properly inflated, the
vehicle is on level ground and there is no
excess weight in the vehicle that would
affect the level of the vehicle.
First, open the hood.
The vertical adjustment bolt is behind the
headlight. Turn the adjustment bolt clock-
wise to raise the headlight beam. Turn the
adjustment bolt counterclockwise to lower
the headlight beam.
The horizontal adjustment bolt is also be-
hind the headlight. Turn the adjustment bolt
clockwise to turn the headlight beam left,and turn it counterclockwise to turn the
headlight beam right.

If you have a flat tire, see the ``In case of
emergency'' section of this manual.
Maximum inflation pressure
Do not exceed the maximum inflation pres-
sures shown on the side wall of the tire.
Tire inflation pressure
Periodically check the tire pressure (including
the spare). Incorrect tire pressure may ad-
versely affect tire life and vehicle handling. Tire
pressure should be checked when tires are
COLD. Tires are considered COLD after the
vehicle has been parked for three or morehours, or driven less than 1 mile (1.6 km).
COLD tire pressures are shown on the tire
placard affixed to the driver's door center pillar.
WARNING
c
The vehicle weight capacity is indi-
cated on the tire placard. Do not load
your vehicle beyond this capacity.
Overloading your vehicle may result
in reduced tire life, unsafe operating
conditions due to premature tire fail-
ure, or unfavorable handling charac-
teristics and could also lead to a
serious accident. Loading beyond the
specified capacity may also result in
failure of other vehicle components.
cBefore taking a long trip, or when-
ever you have loaded your vehicle
heavily, use a tire pressure gauge to
ensure that the tire pressure is at the
specified level.
cDo not drive your vehicle over 85
MPH (140 km/h) unless it is equipped
with high speed capability tires.
Driving faster than 85 MPH (140
km/h) may result in tire failure, loss
of control and possible injury.
Types of tires
WARNING
When changing or replacing tires, be
sure all four tires are of the same type
(i.e., Summer, All Season or Snow) and
construction. An authorized NISSAN
dealer may be able to help you with
information about tire type, size, speed
rating and availability. Replacement
tires may have a lower speed rating
than the factory equipped tires, and
may not match the potential maximum
vehicle speed. Never exceed the maxi-
mum speed rating of the tire.
All Season tires
NISSAN specifies All Season tires on some
models to provide good performance all
year round, including snowy and icy road
conditions. All Season tires are identified by
``ALL SEASON'' and/or ``M&S'' on the tire
sidewall. Snow tires have better snow trac-
tion than All Season tires and may be more
appropriate in some areas.

WHEELS AND TIRES
Do-it-yourself8-33
ZX

Summer tires
NISSAN specifies summer tires on some
models to provide superior performance on
dry roads. Summer tire performance is sub-
stantially reduced in snow and ice. Summer
tires do not have the tire traction rating
``M&S'' on the tire sidewall.
If you plan to operate your vehicle in snowy
or icy conditions, NISSAN recommends the
use of ``SNOW'' tires or ``ALL SEASON''
tires on all four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rating
to the original equipment tires. If you do not,
it can adversely affect the safety and han-
dling of your vehicle.
Generally, snow tires have lower speed
ratings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed the maximum speed
rating of the tire.
If you plan to operate your vehicle in snowy
or icy conditions, NISSAN recommends the
use of ``SNOW'' tires or ``ALL SEASON''
tires on all four wheels.
For additional traction on icy roads, studdedtires may be used. However, some U.S.
States and Canadian Provinces prohibit
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.
Tire chains
Use of tire chains may be prohibited accord-
ing to location. 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 manufacturer's sug-
gestions.Use only SAE class ªSº chains.
Other types may damage your vehicle. Use
chain tensioners when recommended by
the tire chain manufacturer to ensure a tight
fit. Loose end links of the tire chain must be
secured or removed to prevent the possibil-
ity of whipping action damage to the fenders
or underbody. If possible, avoid fully loading
your vehicle when using tire chains. In ad-
dition, drive at a reduced speed. Otherwise,
your vehicle may be damaged and/or ve-
hicle handling and performance may be
adversely affected.
Never install tire chains on a T-type spare
tire. Do not use tire chains on dry roads.
Tire rotation
NISSAN recommends rotating the tires
every 7,500 miles (12,000 km).
See ``Flat tire'' in the ``In case of emergency''
section for tire replacing procedures.
As soon as possible, tighten the wheel
nuts to the specified torque with a nut
tightening torque:
72 to 87 ft-lb (98 to 118 Nzm)
The wheel nuts must be kept tightened to
specifications at all times. It is recom-
mended that wheel nuts be tightened to
specification at each tire rotation interval.

ZX

WARNING
cAfter rotating the tires, adjust the tire
pressure.
cRetighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
cDo not include the T-type spare tire
in the tire rotation.
Tire wear and damage
WARNING
c
Tires should be periodically inspected
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.
cThe original tires have a built-in
tread wear indicator. When the wear
indicator is visible, the tire should be
replaced.
c
Improper service for a T-type spare tiremay result in serious personal injury. If
it is necessary to repair the T-type
spare tire, contact your 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'' of the ``Technical and
consumer information'' section of this
manual.
WARNING
c
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.

cIf 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.
cDo 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.
cThe use of retread tires is not recom-
mended.
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 per-
formed with the wheels off the vehicle. Spin
balancing the front wheels on the vehicle
could lead to transmission damage.
Care of wheels
cWash the wheels when washing the
vehicle to maintain their appearance.
cClean the inner side of the wheels when
the wheel is changed or the underside of
the vehicle is washed.
cDo not use abrasive cleaners when
washing the wheels.
cInspect wheel rims regularly for dents or
corrosion. Such damage may cause
loss of pressure or poor seal at the tire
bead.
cNISSAN recommends waxing the road
wheels to protect against road salt in
areas where it is used during winter.
Spare tire (T-type spare tire)
Observe the following precautions if the T-type
spare tire must be used, otherwise your vehicle
could be damaged or involved in an accident:
CAUTION
cThe T-type spare tire should be used
only for emergency. It should be re-
placed by the standard tire at the
first opportunity.cDrive carefully while the T-type
spare tire is installed. Avoid sharp
turns and abrupt braking while driv-
ing.
cPeriodically check tire inflation pres-
sure, and always keep it at 60 psi
(420 kPa, 4.2 bar).
cDo not drive your vehicle at speeds
faster than 50 MPH (80 km/h).
cDo not use tire chains on a T-type
spare tire. Tire chains will not fit
properly on the T-type spare tire and
may cause damage to the vehicle.
cWhen driving on roads covered with
snow or ice, the T-type spare tire
should be used on the rear wheel
and the original tire used on the front
wheels (drive wheels). Use tire
chains only on the front two original
tires.
cTire tread of the T-type spare tire will
wear at a faster rate than the original
tire. Replace the T-type spare tire as
soon as the tread wear indicators
appear.

Your new NISSAN has been designed to
have minimum maintenance requirements
with longer service intervals to save you
both time and money. However, some day-
to-day and regular maintenance is essential
to maintain your NISSAN's good mechani-
cal condition, as well as its emission and
engine performance.
It is the owner's responsibility to make sure
the specified periodic maintenance, as well
as general maintenance, is performed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
proper maintenance. You are a vital link in
the maintenance chain.
General maintenance
General maintenance includes those items
which should be checked during normal
day-to-day operation of the vehicle. They
are essential if your vehicle is to continue to
operate properly. It is your responsibility to
perform these maintenance procedures
regularly as prescribed.
These checks or inspections can be done
by yourself, a qualified technician or, if you
prefer, an authorized NISSAN dealer.
Periodic maintenance
The maintenance items listed under peri-
odic maintenance are required to be ser-
viced at regular intervals.
However, under severe driving conditions,
additional or more frequent maintenance is
required.
Where to go for service
If maintenance service is required or your
vehicle appears to malfunction, have the
systems checked and tuned by an autho-
rized NISSAN dealer.
NISSAN technicians are well-trained spe-
cialists who are kept up to date with the
latest service information through technical
bulletins, service tips, and in-dealership
training programs. They are completely
qualified to work on NISSAN vehiclesbe-
forethey work on your vehicle, rather than
after they have worked on it.

may be a need for a wheel alignment.
If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing
may be needed.
Windshield wiper blades* ÐCheck for
cracks or wear if they do not wipe properly.
Doors and hood ÐCheck that all doors
and the hood operate properly. Also ensure
that all latches lock securely. Lubricate
hinges, latches, rollers and links if neces-
sary. Make sure the secondary latch keeps
the hood from opening when the primary
latch is released.
When driving in areas that use road salt or
other corrosive materials, check lubrication
frequently.
Lights* ÐMake sure the headlights, stop
lights, tail lights, turn signal lights, and otherlights 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
